"I hope AVX512 dies a painful death," Linus Torvalds said last month, "and that Intel starts fixing real problems instead of trying to create magic instructions to then create benchmarks that they can look good on."

Friday PC World published some reactions from Intel: Torvalds wasn't the only person to kick AVX-512 in the shins either. Former Intel engineer Francois Piednoel also said the special instruction simply didn't belong in laptops, as the power and die space area trade-offs just aren't worth it.
But Intel Chief Architect Raja Koduri says their community loves it because they're seeing a huge performance boost: "AVX-512 is a great feature. Our HPC community, AI community, love it," Koduri said, responding to a question from PCWorld about the AVX-512 kerfuffle during Intel's Architecture Day on August 11. "Our customers on the data center side really, really, really love it." Koduri said Intel has been able to help customers achieve a 285X increase in performance in "our good old CPU socket" just by taking advantage of the extension...

Koduri acknowledged some validity to Torvald's heat, too. "Linus' criticism from one angle that 'hey, are there client applications that leverage this vector bit yet?' may be valid," he said. Koduri explained further that Intel has to maintain a hardware software contract all the way from servers to laptops, because that's been the magic of the ecosystem. "(That's) the great thing about the x86 ecosystem, you could write a piece of software for your notebook and it could also run on the cloud," Kodori said. "That's been the power of the x86 ecosystem..."

And no, hate on AVX-512 and special instructions all you want, Intel isn't going to change direction. Koduri said it will continue to lean on AVX-512 as well as other instructions. "We understand Linus' concerns, we understand some of the issues with first generation AVX-512 that had impact on the frequencies etc, etc," he said "and we are making it much much better with every generation."
They also summarize some performance testing by blogger Travis Downs, saying it found AVX-512 "doesn't appear to enforce much of a penalty at all on a laptops. Downs' testing found the clock speed only dropped 100MHz when using one active core under AVX-512.

"At least, it means we need to adjust our mental model of the frequency related cost of AVX-512 instructions," Downs concluded. "Rather than 'generally causing significant downclocking,' on this Ice Lake chip we can say that AVX-512 causes insignificant or zero licence-based downclocking and I expect this to be true on other Ice Lake client chips as well."

Synology today added a new NAS to its lineup: "DiskStation DS1520+," with five bays. It also has two NVMe PCIe SSD slots for cache. From a report: "Featuring the Intel Celeron Processor J4125, DS1520+ provides a performance boost that sees a 126 percent increase in website responsiveness and a 19.8 percent increase in compute-tasks. The DS1520+ provides dual M.2 2280 NVMe SSD cache slots, along with four 1GbE network ports. DS1520+ comes equipped with five bays that support HDDs and SSDs of up to 16TB. If the need for storage grows, users can expand their DS1520+ using Synology expansion units (purchased separately), giving users a maximum raw capacity of 240TB," says Synology. It's priced at $700, but BetaNews, which has listed the full specs and other details, says Amazon is already selling it at $650.

InfoQ reports on a new security group that launched last week: Supported by The Linux Foundation, the Open Source Security Foundation (OpenSSF) aims to create a cross-industry forum for a collaborative effort to improve open source software security. The list of initial members includes Google, Microsoft, GitHub, IBM, Red Hat, and more.

"As open source has become more pervasive, its security has become a key consideration for building and maintaining critical infrastructure that supports mission-critical systems throughout our society. It is more important than ever that we bring the industry together in a collaborative and focused effort to advance the state of open source security. The world's technology infrastructure depends on it."

Microsoft CTO for Azure Mark Russinovich explained clearly why open source security must be a community effort:

"Open-source software is inherently community-driven and as such, there is no central authority responsible for quality and maintenance. [...] Open-source software is also vulnerable to attacks against the very nature of the community, such as attackers becoming maintainers of projects and introducing malware. Given the complexity and communal nature of open source software, building better security must also be a community-driven process."
Also joining the group are Intel, IBM, Uber, and VMWare, according to Foundation's inaugural announcement, which promises its governance and decisions "will be transparent, and any specifications and projects developed will be vendor agnostic."

Slashdot reader Tekla Perry is also senior editor at IEEE Spectrum, and brings a story about San Diego's 3,300 "smart streetlights," each one equipped with "an Intel Atom processor, half a terabyte of storage, Bluetooth and Wi-Fi radios, two 1080p video cameras, two acoustical sensors, and environmental sensors that monitor temperature, pressure, humidity, vibration, and magnetic fields."

San Diego's smart streetlights were supposed to save money and inspire entrepreneurs to use streetlight sensor data to develop apps that would make the city a better place. The money savings didn't add up and the apps never emerged. Instead, the San Diego police realized the video data, intended to be processed at the edge by AI algorithms [and deleted after 5 days], could be tapped directly for law enforcement. Now consumer groups are looking to the city to pass legislation governing the use of data, and other cities are opting to avoid such issues by leaving cameras out of future intelligent lighting systems.
The first video accessed by police exonerated a person they'd arrested for murder in August of 2018. But over the next 10 months they'd accessed 99 more videos to investigate what they called "serious" crimes, a number climbing to up to 175 videos by early 2020. "The list included murders, sexual assaults, and kidnappings — but it also included vandalism and illegal dumping, which caused activists to question the city's definition of 'serious'..." according to IEEE Spectrum. "To date, San Diego police have tapped streetlight video data nearly 400 times, including this past June, during investigations of incidents of felony vandalism and looting during Black Lives Matter protests."

Morgan Currie, a lecturer in data and society at the University of Edinburgh, tells the site it's "a classic example of how data collection systems are easily retooled as surveillance systems, of how the capacities of the smart city to do good things can also increase state and police control."

Intel on Thursday disclosed a new method for making transistors on semiconductors that its chief architect said could boost the performance Intel's next round of processors by as much as 20%. From a report: The Santa Clara, California-based company is one of the few remaining in the world that both designs and manufactures its own chips. But its manufacturing operations have become a concern among investors after Intel last month said that its next-generation chip-making process, called its 7-nanometer process node, would be delayed. Analysts believe the delays could cement the lead that rivals such as Taiwan Semiconductor Manufacturing Co have gained in making smaller, more power efficient chips. Intel's shares have fallen nearly 20% since the delays were disclosed. On Thursday, Intel sought to buck the notion that the single-number names given to each generation of chip process node tell the entire story by disclosing improvements on its existing 10-nanonmeter process node. It announced a new way of making what it now calls "SuperFin" transistors, which, along with a new material being used to improve the capacitors on chips, is expected to boost the performance of Intel's forthcoming processors, despite their still being made on 10-nanometer manufacturing lines.

As Apple's Mac computers begin their two-year transition from Intel- to Apple-developed CPUs later this year, one feature that's going away is Boot Camp -- the Mac's ability to boot directly into Windows and run PC apps natively. But Corel's Parallels Desktop will still be there to let Mac users run Windows, and in this year's version 16, it will thankfully be faster, more compatible, and easier to use than ever. From a report: Like Parallels Desktop 15, version 16 is an emulator that allows users to load a complete operating system or individual apps within macOS, treating them as windows within the Mac environment. Once again, high-end Business, mid-range Pro, and regular Standard versions are available. With the latest Business version of Parallels Desktop, an IT department can create, deploy, and remotely manage a profile-customized Windows system that Mac users download in a compact file size and expand on their own machines. A simpler Pro version includes the file-compacting feature used to more easily transfer virtual machines between computers, achieving as much as 20 times compression for Linux installs and 75% faster Linux git status executions. The standard version includes a manual Free Up Disk Space feature with archiving and space reclaiming options.

With SoftBank's Masayoshi Son trying to sell ARM, a columnist for the Observer newspaper has a suggestion for the U.K. government (and specifically Brexit Tories), calling the Cambridge-based company "a kind of public-interest commercial company: licensing state-of-the art instruction sets that can be implemented in silicon architecture by everyone. It was in nobody's pocket." Its business, as its chief founder, Tudor Brown, acknowledges, relied on it never betraying its neutrality... A future owner could almost trash Arm in the pursuit of its own commercial ends. Nvidia, reported to be in advanced talks with Son, is just such a possible owner. Rooted in the games industry, it has found to its surprise that its processing units are much in demand as artificial intelligence applications mushroom. Son wanted to sell Arm to an industry coalition that might protect the company's independence and business model. None could be found, so, desperate for cash, given a string of failed and written-down investments (WeWork, Uber etc), he is now having to sup with a buyer that can only destroy Arm.

Nvidia's ambitions are scarcely hidden. Once it owns Arm it will withdraw its licensing agreements from its competitors, notably Intel and Huawei, and after July next year take the rump of Arm to Silicon Valley, just as Google has done with the British AI company DeepMind. Arm, and Britain's hopes to be a player in hi-tech, will be dead.

Ownership is fundamental and the lesson of the story is that unless Britain creates the legal, cultural and institutional framework allowing companies such as Arm (or DeepMind) to have anchor shareholders — or simply allowing founder shareholders to have powerful differential voting rights as in the U.S. and Canada — we are condemned to inferiority. But even now Britain could act. The government could offer a foundational investment of, say, £3bn-£5bn and invite other investors — some industrial, some sovereign wealth funds, some commercial asset managers — to join it in a coalition to buy Arm and run it as an independent quoted company, serving the worldwide tech industry... if Britain is to develop an industrial strategy, this is how it must act...

A successful capitalism is always about framing innovative private dynamism within a fit-for-purpose regulatory and ownership architecture designed by the state, a reality that neither major party has ever understood. The open question is whether Brexit Tories, forced by reality, might change. This kind of audacious deal could appeal to Johnson and Cummings, a statement of intent to match China in our commitment to a decisive presence in 21st-century hi-tech.

Brexit was meant to give Britain the freedom to make this kind of move.

This week saw the release Linux 5.8, which Linus Torvalds called "one of our biggest releases of all time," reports TechRepublic: The new version of the Linux kernel brings a number of updates to Linux 5.7 spanning security, core components, drivers, memory management, networking and improvements to the kernel's design, amongst others. This includes updates for Microsoft's Hyper-V virtualization platform, Intel Tiger Lake Thunderbolt support, improvements to Microsoft's exFAT file system, and support for newer Intel and ARM chips.

Torvalds said the kernel had received over 15,000 merge requests and that around 20% of all the files in the kernel source repository had been modified. "That's really a fairly big percentage, and while some of it is scripted, on the whole it's really just the same pattern: 5.8 has simply seen a lot of development," Torvalds said.

Translated into numbers, Linux 5.8 includes over 800,000 new lines and over 14,000 changed files. It also received one of the biggest number of merge requests during its merge window — over 14,000 non-merge commits and more than 15,000 including merges, according to Torvalds. "5.8 looks big. Really big," he added.

Using millions of programs in online repositories, Intel, Georgia Tech, and MIT researchers created a tool called MISIM (Machine Inferred code Similarity) with a database of code scored by the similarity of its outcomes to suggest alternatives (and corrections) to programmers.

The hope is "to aid developers with nitty-gritty choices like 'what is the most efficient way to use this API' or 'how can I correctly validate this input',"Ryan Marcus, scientist at Intel Labs, told ZDNet. "This should give engineers a lot more time to focus on the elements of their job that actually create a real-world impact..." Justin Gottschlich, the lead for Intel's "machine programming" research team, told ZDNet that as software development becomes ever-more complex, MISIM could have a great impact on productivity. "The rate at which we're introducing senior developers is not on track to match the pace at which we're introducing new chip architectures and software complexity," he said. "With today's heterogeneous hardware — CPUs, GPUs, FPGAs, ASICs, neuromorphic and, soon, quantum chips — it will become difficult, perhaps impossible, to find developers who can correctly, efficiently, and securely program across all of that hardware."

But the long-term goal of machine programming goes even further than assisting software development as it stands today. After all, if a technology can assess intent and come up with relevant snippets of code in response, it doesn't seem far-fetched to imagine that the algorithm could one day be used by any member of the general public with a good software idea. Combined with natural language processing, for example, MISIM could in theory react to verbal clues to one day let people write programs simply by describing them. In other words, an Alexa of sorts, but for software development.

Gottschlich explained that software creation is currently limited to the 27 million people around the world who can code. It is machine programming's ultimate goal to expand that number and one day, let people express their ideas in some other fashion than code — be it natural language, visual diagrams or even gestures.
Intel currently plans to use the new tool internally.

Apple is announcing updates for both the 27-inch and 21.5-inch iMacs. It's updating the processors inside to Intel's 10th Gen Comet Lake processors and also switching out the webcam to a higher-resolution 1080p HD sensor instead of the low-res 720p found in other Macs. From a report: SSDs are now standard across the line, and there will be a bunch of new configuration options -- including a "nano-texture" version with less reflective matte glass. The 27-inch iMac starts at $1,799, is available to order today, and will ship this week. The 21.5-inch iMac starts at $1,099 and will ship next week. Apple is also giving the iMac Pro a small spec bump, making the 10-core Intel chips the new baseline for $4,999 -- also shipping next week. (Oddly, the iMac Pro is not otherwise getting updated.)

This is not the major redesign that has been rumored (and hoped for), nor is it the first ARM-based Mac. Instead, the 2020 iMacs look identical to the last generation, including the large black bezel all the way around the screen and the big metal chin at the bottom. Apple says that, as it noted at WWDC, it intends to support Intel-based Macs for many years to come. The webcam might be the biggest day-to-day upgrade for most users. It's 1080p, but Apple says that the new T2 chip enables some new features beyond the improved resolution like tone mapping, exposure control, and face detection. Apple says the improved camera features will work in any videoconferencing app, not just FaceTime.

Google and Apple, which already battle over mobile operating systems, are opening a new front in their fight. How that plays out may determine the future of the web. From a report: Google was born on the web, and its business reflects its origin. The company depends on the web for search and advertising revenue. So it isn't a surprise that Google sees the web as key to the future of software. Front and center are web apps, interactive websites with the same power as conventional apps that run natively on operating systems like Windows, Android, MacOS and iOS. Apple has a different vision of the future, one that plays to its strengths. The company revolutionized mobile computing with its iPhone line. Its profits depend on those products and the millions of apps that run on them. Apple, unsurprisingly, appears less excited about developments, like web apps, that could cut into its earnings.

The two camps aren't simply protecting their businesses. Google and Apple have philosophical differences, too. Google, working to pack its dominant Chrome browser with web programming abilities, sees the web as an open place of shared standards. Apple, whose Safari browser lacks some of those abilities, believes its restraint will keep the web healthy. It wants a web that isn't plagued by security risks, privacy invasion and annoyances like unwanted notifications and permission pop-ups. Google leads a collection of heavy-hitting allies, including Microsoft and Intel, trying to craft new technology called progressive web apps, which look and feel like native apps but are powered by the web. PWAs work even when you have no network connection. You can launch PWAs from an icon on your phone home screen or PC start menu, and they can prod you with push notifications and synchronize data in the background for fast startup. PWA fans include Uber, travel site Trivago and India e-commerce site Flipkart. Starbucks saw its website usage double after it rolled out a PWA.

The split over native apps and web apps is more than just a squabble between tech giants trying to convert our lives online into their profits. How it plays out will shape what kind of a digital world we live in. Choosing native apps steers us to a world where we're locked into either iOS or Android, limited to software approved by the companies' app stores and their rules. Web apps, on the other hand, reinforce the web's strength as a software foundation controlled by no single company. A web app will work anywhere, making it easier to swap out a Windows laptop for an iPad. "What you're seeing is the tension between what is good for the user, which is to have a flexible experience, and what's good for the platform, which is to keep you in the platform as much as possible," said Mozilla Chief Technology Officer Eric Rescorla.

Facebook in recent weeks has approached a handful of small venture capital firms to discuss becoming an investor in their funds, The Information reported Tuesday, citing people familiar with the matter. The VC strategy, which also includes direct investments in startups, aims to give the social network early, valuable insight into a wider swath of companies. From a report: To run the new investing initiative, Facebook recently appointed Sunita Parasuraman, a nine-year veteran of the company who previously ran the treasury for its embattled Libra cryptocurrency project. Former Kleiner Perkins general partner Eric Feng, now a Facebook employee, is helping approach funds, sources say. The moves come as Facebook fends off antitrust scrutiny of its acquisitions and attempts to find new ways to counter growing competitive threats like TikTok. While Microsoft, Intel and others for years have taken stakes in startups through VC subsidiaries, Facebook has shied away from adopting a formal investing program until recently. Instead, it has made one-off investments, such as its recent $5.7 billion investment in Indian tech conglomerate Jio Platforms. Google, in contrast, has multiple, long-running venture arms, including GV, which has backed big-name companies like Slack and Uber.

FallOutBoyTonto shares a report from AnandTech: Coming in the wake of last week's disclosure that their 7nm yields are roughly a full year behind schedule, Intel this afternoon has announced that they are reorganizing the technology side of the company. Key to this change is that Intel is breaking up its monolithic Technology, Systems Architecture and Client Group (TSCG) into several smaller groups, all of which will report directly to CEO Bob Swan. Meanwhile Intel's chief engineering officer, Dr. Murthy Renduchintala, who had been leading the TSCG, will be departing the company at the end of next week. The reorganization is effective immediately.

As a result of this reorganization, TSCG is being broken up into five groups focusing on manufacturing and architecture. These are:

- Technology Development: Focused on developing next-generation process nodes. Led by Dr. Ann Kelleher.
- Manufacturing and Operations: Focused on ramping current process nodes and building out new fab capacity. Led by Keyvan Esfarjani.
- Design Engineering: A recently-created group responsible for Intel's technology manufacturing and platform engineering. Led on an interim basis by Josh Walden while Intel searches for a permanent leader.
- Architecture, Software and Graphics: Developing Intel's architectures and associated software stacks. Led by Raja Koduri (continuing).
- Supply Chain: Handling Intel's supply chain and relationships with important suppliers. Led by Dr. Randhir Thakur (continuing).

If you've been following along with Intel's troubles moving away from its 14nm process to 10nm over the years, you probably won't be surprised to learn that the company is now having trouble getting its 7nm process off the ground. From a report: On its Q2 earnings call this week, Intel revealed that it's pushing back its previously planed 7nm rollout by six months -- and that yields for the process are now a year behind schedule. This means that Intel can't produce 7nm chips in an economically viable way at the moment. Intel originally expected to catch up with AMD's 7nm chips in 2021, but didn't say when in 2021. With these new delays, that puts Intel's 7nm chip debut in 2022, at the earliest. By then, AMD may already be on its Ryzen 6000 5nm chips on Zen 4 architecture, according to its roadmap -- though that's assuming AMD doesn't run into any delays itself.

However, there is some good news on the 10nm front. From Intel's Q2 2020 press release, the company says it's "accelerating its transition to 10nm products this year" and growing its portfolio of 10nm-based Intel Core processors. That includes its Tiger Lake chips and its first 10nm-based server CPU Ice Lake. Additionally, Intel said it "expects to deliver a new line of client CPUs (code-named Alder Lake), which will include its first 10nm-based desktop CPU, and a new 10nm-based server CPU (code-named Sapphire Rapids)." Intel originally announced its 10nm chips in 2015, but confirmed it was having yield issues and other problems that July.

MojoKid writes: Word across a number of business and tech press publications tonight is that NVIDIA is reportedly pursuing a possible acquisition of Arm, the chip IP juggernaut that currently powers virtually every smartphone on the planet (including iPhones), to a myriad of devices in the IoT and embedded spaces, as well as supercomputing and in the datacenter. NVIDIA has risen in the ranks over the past few years to become a force in the chip industry, and more recently has even been trading places with Intel as the most valuable chipmaker in the United States, with a current market cap of $256 billion. NVIDIA has found major success in consumer and pro graphics, the data center, artificial intelligence/machine learning and automotive sectors in recent years, meanwhile CEO Jensen Huang has expressed a desire to further branch out into the growing Internet of Things (IoT) market, where Arm chip designs flourish. However, Arm's current parent company, SoftBank, is looking for a hefty return on its investment and Arm reportedly could be valued at around $44 billion, if it were to go public. A deal with NVIDIA, however, would short-circuit those IPO plans and potentially send shockwaves in the semiconductor market.

An anonymous reader quotes a report from Motherboard: The fugitive executive of the embattled payment startup Wirecard was mentioned in a brazen and bizarre attempt to purchase hacking tools and surveillance technology from an Italian company in 2013, an investigation by Motherboard and the German weekly Der Spiegel found. Jan Marsalek, a 40-year-old Austrian who until recently was the chief operating officer of the rising fintech company Wirecard, seems to have taken a meeting with the infamous Italian surveillance technology provider Hacking Team in 2013. At the time, Marsalek is described as an official representative of the government of Grenada, a small Caribbean island of around 100,000 people, in a letter that bears the letterhead of the Grenada government. The documents were included in a cache published after Hacking Team was hacked in 2015. In recent days, Marsalek has been described as the 'world's most wanted man.'

It is unclear from the documents alone whether Marsalek played any role in the attempt to procure hacking tools, or whether his name was simply used. However, months before Marsalek appears to have contacted with Hacking Team, several websites with official sounding names such as StateOfGrenada.org were registered under the name of Jan Marsalek, as Der Spiegel reported last week. Some of the sites were registered with Marsalek's phone number and his Munich address at the time, and the servers were apparently operated from Germany. Wirecard provided digital payment services and was considered one of the most important companies in the financial tech industry. Wirecard offered a mobile payment app called Boon, which was essentially a virtual MasterCard card, it also offered a prepaid debit card called mycard2go, and worked with companies such as KLM, Rakuten, and Qatar Airways to manage their online transactions. The company suddenly collapsed in June after German regulators raided its headquarters as part of an investigation into fraudulent stock price manipulation and 1.9 billion euros that are missing from the company's books. Marsalek is now a fugitive and a key suspect in the German investigation. He reportedly fled to Belarus, and is now hiding in Russia under the protection of the FSB, according to German news reports. In the past, he was involved in other strange dealings: he bragged about an attempt to recruit 15,000 Libyan militiamen, and about a trip to Syria along with Russian military, according to the Financial Times.

MojoKid writes: Today AMD took the wraps off a new line of desktop processors based on its Zen 2 architecture but also with integrated Radeon graphics to better compete against Intel with OEM system builders. These new AMD Ryzen 4000 socket AM4 desktop processors are essentially juiced-up versions of AMD's already announced Ryzen 4000 laptop CPUs, but with faster base and boost clocks, as well as faster GPU clocks for desktop PCs. There are two distinct families AMD Ryzen 4000 families, a trio of 65-watt processors that include the Ryzen 3 4300G (4-core/8-thread), Ryzen 5 4600G (6-core/12-thread), and the flagship Ryzen 7 4700G, offering 8 cores/16 threads, base/boost clocks of 3.6GHz/4.4GHz, 12MB cache, and 8 Radeon Vega cores clocked at 2100MHz. AMD is also offering three 35-watt processors -- Ryzen 3 4300GE, Ryzen 5 4600GE, and the Ryzen 7 4700GE -- which share the same base hardware configurations as the "G" models but slightly lower CPU/GPU clocks to reduce power consumption. In addition AMD also announced its Ryzen Pro 4000 series for business desktops, which also include a dedicated security processor and support for AMD Memory Guard full system memory encryption. As you might expect, specs (core/cache counts, CPU/GPU clocks) for the Ryzen Pro 4000G (65W) and Ryzen Pro 4000GE (35W) largely line up with their consumer desktop counterparts.

"Google has decided to disable a feature in Windows 10 version 2004 that allowed Chrome and Microsoft Edge browsers to use a lot less RAM," reports ZDNet: Windows 10 gave Win32 apps including Chrome access to a 'segment heap' API to allow apps to reduce memory usage, but as Techdows spotted, Chromium engineers have decided for now to turn off the feature by default in Chrome 85 after discovering it has a negative impact on CPU usage. Chrome 85 should reach stable status in August...

The CPU issue was discovered by an Intel engineer who found that when Chrome used segment heap, it led to significant performance regression in benchmarks on a PC with an Intel Core i9-9900K processor...

Microsoft has defended the trade-off between memory and CPU but conceded it can be implemented better to reduce the impact on CPU performance. "It is common practice to trade one resource for another. More often it's increased memory usage for reduced CPU usage. In this case it's increased CPU usage for dramatically reduced memory usage, or more accurately commit," wrote a Microsoft employee... "In the short term this is a good trade-off of one resource for another as memory/commit usage is a significant pain point for browser users," argued the Microsoft employee....

However, Chromium developers want to see more evidence about the possible impact of Chrome using segment heap... "The CPU cost (10% slowdown on Speedometer 2.0, 13% increase in CPU/power consumption) is too great for us to keep."

AMD finally brings a workstation-class -- in other words, security-conscious -- processor to challenge the Intel Xeon on the desktop with its Ryzen Threadripper Pro. With up to 64 cores, the pro version of AMD's multicore powerhouse Threadripper processors incorporates essentials like support for massive amounts of memory and board-level security, critical for uses which move a ton of sensitive data, ranging from aerospace visualization to Hollywood video editing and CGI rendering. The CPU debuts in Lenovo's ThinkStation P620; Lenovo has a limited exclusive on the processor. From a report: The CPU comes in four variants: 3945WX (12 cores, with the fastest single-core speeds), 3955WX (16 cores), 3975WX (32 cores) and 3995WX (64 cores). At the moment, to achieve core counts that high with the Intel Xeon, you have to use multiple CPUs. They all come with some of the perks of AMD's architecture, including support for PCI Gen4 -- in this case, up to 128 lanes. And the Pro versions add support for more types of memory, notably RDIMM and LRDIMM, over the high-end consumer-focused Threadripper, plus 8 memory channels vs. 4, which lets it support up to 2TB of memory. On the downside, while AMD supports faster internal transfers than Intel via PCI 4, it doesn't offer any high-speed external data transfer capabilities a la Thunderbolt 3. And in fact, the ThinkStation P620's fastest connections are USB 3.2 Gen 2 and 10Gb Ethernet.
