Ahead of the annual Supercomputing 2018 conference next week, Intel today announced part of its upcoming Cascade Lake strategy. From a report: The company teased plans for a new Xeon platform called Cascade Lake Advanced Performance, or Cascade Lake-AP, this morning ahead of the Supercomputing 2018 conference. This next-gen platform doubles the cores per socket from an Intel system by joining a number of Cascade Lake Xeon dies together on a single package with the blue team's Ultra Path Interconnect, or UPI. Intel will allow Cascade Lake-AP servers to employ up to two-socket (2S) topologies, for as many as 96 cores per server.

Intel chose to share two competitive performance numbers alongside the disclosure of Cascade Lake-AP. One of these is that a top-end Cascade Lake-AP system can put up 3.4x the Linpack throughput of a dual-socket AMD Epyc 7601 platform. This benchmark hits AMD where it hurts. The AVX-512 instruction set gives Intel CPUs a major leg up on the competition in high-performance computing applications where floating-point throughput is paramount. Intel used its own compilers to create binaries for this comparison, and that decision could create favorable Linpack performance results versus AMD CPUs, as well.

System76 is ready to share specifics about its new computer. From a report: There are three models from which to choose, and all three can apparently be configured with with Intel or AMD processors. This is refreshing news, as historically, System76 machines were an Intel-only affair. AMD has been more friendly to the Linux community over recent years, so I am happy to see System76 giving that option too.

1. Thelio (Up to 32GB RAM, 24TB storage) treks through tasks with ease despite its compact footprint.
2. Thelio Major (Up to 128GB RAM, 46TB storage) boasts stellar performance, allowing maximum configurability with up to 4 GPUs to tackle the most astronomical projects.
3. Thelio Massive (Up to 768GB of ECC Memory, 86TB storage) is the epitome of performance among workstations, offering maximum throughput and accuracy for demanding computational workloads.

Pricing starts at $1099.99, but that will obviously increase based on the specs you choose. Keep in mind, however, the computer will not ship until December. Full specs in the story above. In a statement, the company said, "Thelio Systems are designed to be easily expandable, making personalizing the computer a tantalizingly easy process. Slip in drives, add memory, and upgrade graphics cards at will. Additionally, the open hardware design that Thelio is built upon allows the user to easily learn how their computer works and make modifications using this information. Customization is simple to ensure that the computer encompasses people's needs, as well as their personality."

MojoKid writes: AMD launched its line of second generation Ryzen Threadripper CPUs over the summer, but the company offered 16-core and 32-core versions of it only at the time. Today however, the company began shipping 12-core and 24-core versions of the high-end desktop and workstation chips, dubbed Ryzen Threadripper 2920X and 2970WX, respectively. All 2nd Generation Ryzen Threadripper processors feature an enhanced boost algorithm that came with AMD's Zen+ architecture that is more opportunistic and can boost more cores, more often. They also offer higher-clocks, lower-latency, and are somewhat more tolerant of higher memory speeds. All of AMD's Ryzen Threadripper processors feature 512K of L2 cache per core (6MB total on the 2920X and 12MB on the 2970WX), quad-channel memory controllers (2+2), and are outfitted with 64 integrated PCI Express Gen 3 lanes. The new Ryzen Threadripper 2920X has a 180W TDP, while the 2970WX has a beefier 250W TDP. In highly threaded workloads, the Threadripper 2920X outpaces a far more expensive 10-core Intel Core i9-7900X, while the 24-core / 48-thread Threadripper 2970WX is the second most powerful desktop processor money can buy right now. It's faster than Intel's flagship Core i9-7980XE, and trailed only AMD's own 32-core Threadripper 2990WX. Pricing for the new chips falls in at $649 for the 12-core 2920X and $1299 for the 24-core Threadripper 2970WX.

MojoKid writes: Intel lifted the embargo veil today on performance results for its new Core i9-9900K 9th Gen 8-core processor. Intel claims the chip is "the best CPU for gaming" due to its high clock speeds and monolithic 8-core/16-thread design that has beefier cache memory (now 16MB). The chip also has 16-lanes of on-chip PCIe connectivity, official support for dual-channel memory up to DDR4-2666, and a 95 watt TDP. Intel also introduced two other 9th Gen chips today. Intel's Core i7-9700K is also an 8-core processor, but lacks HyperThreading, is clocked slightly lower, and has 4MB of smart cache disabled (12MB total). The Core i5-9600K takes things down to 6 cores / 6 threads, with a higher base clock, but lower boost clock and only 9MB of smart cache. In benchmark testing, the high-end Core i9-9900K's combination of Intel's latest microarchitecture and boost frequencies of up to 5GHz resulted in the best single-threaded performance seen from a desktop processor to date. The chip's 8-cores and 16-threads, larger cache, and higher clocks also resulted in some excellent multi-threaded scores that came close to catching some of Intel's many-core Core X HEDT processors in a few tests. The Core i9-9900K is a very fast processor, but it is also priced as such at $488 in 1KU quantities. That makes it about $185 to $225 pricier than AMD's Ryzen 7 2700X, which is currently selling for about $304 and performs within 3% to 12% of Intel's 8-core chip, depending on workload type.

Ubuntu 18.10 Cosmic Cuttlefish, the latest version of Ubuntu, is now available to download. From a report: Under the hood, the Cosmic Cuttlefish boasts the 4.18 Linux Kernel. This updates comes with better support for for AMD and Nvidia GPU, USB Type-C and Thunderbolt, a way for unprivileged users to mount Filesystem in Userspace (FUSE) can be mounted by, and CPUfreq performance improvements. On top of this, you'll find the freshest version of GNOME 3.30. You can, of course, use other desktops, but GNOME, since Ubuntu 17.10, is Ubuntu's default desktop. You'll be glad to know that GNOME is faster than it has been for a while. That's because some nasty memory leaks have been patched. Canonical has also added some performance tweaks that didn't make it into the GNOME 3.30 upstream. Ubuntu 18.10 also comes with a new desktop theme, the Yaru Community theme installed by default, for your visual enjoyment. Further reading: Ubuntu 18.10: What's New?

On Monday, Intel unveiled the 9th Gen Core i9-9900K, which will rival AMD's Ryzen 2700X when it goes on sale in two weeks. We will soon be reading reviews of the 9th Gen Core i9-9900K, which Intel claims is the "world's best gaming processor," to see how exactly it fares against its AMD counterpart. But as reviewers test the new CPU and comply with an NDA/embargo (non-disclosure agreement) with Intel, which requires them to not share performance data of Intel's new CPU for another few days, surprisingly, one publication has already made a bold claim. In a story published this week, news outlet PCGamesN said, "Intel's Core i9 9900K is up to 50% faster than AMD's Ryzen 7 2700X in games." The publication cites data from an Intel-commissioned report [PDF] by third-party firm Principle Technologies to make the claim. TechSpot explains the issues with this: So Intel can go and publish their own "testing" done suspiciously through a third party ten days before reviews, while reviewers are prohibited from refuting the claims due to the NDA. First bad sign. Scrolling down PCGamesN says the following when looking over Intel's commissioned benchmarks. "But the real point of all this is for Intel to be able to hold out the 9900K as hands down the best gaming processor compared with the AMD competition, and in that it seems to have excelled. On some games, such as Civ 6 and PUBG, the performance delta isn't necessarily that great, but for the most part you're looking at between 30 and 50% higher frame rates from the 9900K versus the 2700X."

Right away many of the results looked very suspect to me, having spent countless hours benchmarking both the 2700X and 8700K, I have a good idea of how they compare in a wide range of titles and these results looked very off. Having spotted a few dodgy looking results my next thought was, why is PCGamesN publishing this misleading data and why aren't they not tearing the paid benchmark report apart? Do they simply not know better?

Over at the Principled Technologies website you can find the full report which states how they tested and the hardware used. Official memory speeds were used which isn't a particularly big deal, though they have gone out of their way to handicap Ryzen, or at the very least expose its weaknesses. Ryzen doesn't perform that well with fully populated memory DIMMs, two modules is optimal. However timings are also important and they used Corsair Vengeance memory without loading the extreme memory profile or XMP setting, instead they just set the memory frequency to 2933 and left the ridiculously loose default memory timings in place. These loose timings ensure compatibility so systems will boot up, but after that point you need to enable the memory profile. It's misleading to conduct benchmarks without executing this crucial step.

Microsoft unveiled a bunch of new hardware during a press event last night, but one of the most interesting announcements the company made was their new "Your Phone" app for Windows 10. Basically, the feature will let Android users mirror any app on their device to a Windows 10 desktop. The Verge's Tom Warren writes about how Microsoft is embracing Android as the mobile version of Windows: We've seen a variety of ways of bringing Android apps to Windows in recent years, including Bluestacks and even Dell's Mobile Connect software. This app mirroring is certainly easier to do with Android, as it's less restricted than iOS. Still, Microsoft's welcoming embrace of Android in Windows 10 with this app mirroring is just the latest in a number of steps the company has taken recently to really help align Android as the mobile equivalent of Windows.

Microsoft Launcher is designed to replace the default Google experience on Android phones, and bring Microsoft's own services and Office connectivity to the home screen. It's a popular launcher that Microsoft keeps updating, and it's even getting support for the Windows 10 Timeline feature that lets you resume apps and sites across devices. All of this just reminds me of Windows Phone. It's only been three years since Microsoft launched its Lumia 950 Windows 10 Mobile device at a packed holiday hardware event. Windows Phone has vanished in the last couple of years, and Microsoft finally admitted Windows Phone was dead nearly a year ago. The software maker has now embraced the reality that people don't need Windows on a phone. Instead, it's embracing Android as the mobile version of Windows.

Paul Alcorn reporting for Tom's Hardware: AMD listed the Ryzen 7 2800H and the Ryzen 5 2600H on its website. These new processors bring the inherent goodness of the Raven Ridge architecture, found in the Ryzen 5 2400G and the Ryzen 3 2200G, to gaming notebooks. As such, these processors come with AMD's Zen compute cores paired with the Vega graphics architecture, and they are also AMD's first processors to support DDR4-3200 as a base specification. Both new models feature a similar design as their desktop counterparts, albeit with slightly redesigned in frequencies to adjust for the flimsy cooling in mobile form factors and battery life limitations. That's reflected in the processors' reduced 45W TDP (thermal design power), which is much lower than the 65W TDP found on the desktop parts. AMD does give vendors some wiggle room with a configurable TDP (cTDP) range that spans between 35W and 45W.

The Ryzen 7 2800H is analogous to the 2400G, but it comes with a 3.3 GHz base and 3.8 GHz boost clocks. The four-core, eight-thread CPU is complemented by Vega graphics with 11 CU (Compute Unit) clocked up to a max of 1,300 MHz, which is a nice boost over its desktop counterpart. The Ryzen 5 2600H is similar to the 2200G, but it's four cores are hyper-threaded, which is a big bonus. The Vega graphics come with 8 CUs and boost up to 1,100 MHz.

AMD announced two new second-generation Ryzen CPUs this morning. From a report: The Ryzen 5 2500X and Ryzen 3 2300X bring Precision Boost 2 and XFR 2 to quad-core Ryzens without integrated graphics, but there's a catch: these chips appear to be available exclusively to system integrators and OEMs for use in prebuilt systems. AMD is debuting the Ryzen 5 2500X in cooperation with Acer in the form of the Nitro 50 desktop PC. AMD says the Ryzen 5 2500X and Ryzen 3 2300X each use a single enabled core complex (or CCX) from the two available on Pinnacle Ridge Zeppelin dies to get their four cores. Recall that the Ryzen 5 1500X instead used two cores from each CCX to get its core count. A consequence of this architectural change versus the Ryzen 5 1500X is that the Ryzen 5 2500X now has 8 MB of L3 cache, down from 16 MB. That puts both the Ryzen 5 2500X and Ryzen 3 2300X on par with the Ryzen 3 1300X and Ryzen 3 1200 on a cache-capacity basis.

This week in Vancouver, Linux kernel developer Greg Kroah-Hartman criticized Intel's slow initial response to the Spectre and Meltdown bugs in a talk at the Open Source Summit North America. An anonymous reader quotes eWeek: Kroah-Hartman said that when Intel finally decided to tell Linux developers, the disclosure was siloed.... "Intel siloed SUSE, they siloed Red Hat, they siloed Canonical. They never told Oracle, and they wouldn't let us talk to each other." For an initial set of vulnerabilities, Kroah-Hartman said the different Linux vendors typically work together. However, in this case they ended up working on their own, and each came up with different solutions. "It really wasn't working, and a number of us kernel developers yelled at [Intel] and pleaded, and we finally got them to allow us to talk to each other the last week of December [2017]," he said. "All of our Christmas vacations were ruined. This was not good. Intel really messed up on this," Kroah-Hartman said...

"The majority of the world runs Debian or they run their own kernel," Kroah-Hartman said. "Debian was not allowed to be part of the disclosure, so the majority of the world was caught with their pants down, and that's not good." To Intel's credit, Kroah-Hartman said that after Linux kernel developers complained loudly to the company in December 2017 and into January 2018, it fixed its disclosure process for future Meltdown- and Spectre-related vulnerabilities... "Intel has gotten better at this," he said.

An interesting side effect of the Meltdown and Spectre vulnerabilities is that Linux and Windows developers are now working together, since both operating systems face similar risks from the CPU vulnerabilities. "Windows and Linux kernel developers now have this wonderful back channel. We're talking to each other and we're fixing bugs for each other," Kroah-Hartman said. "We are working well together. We have always wanted that."

"Using the newly minted Linux 4.19 feature code, fresh benchmarks were carried out looking at the performance cost of Spectre/Meltdown/Foreshadow mitigations on Intel Xeon v. AMD EPYC CPUs," writes an anonymous Slashdot reader: Workloads affected by these CPU vulnerabilities mainly deal with I/O and frequent kernel calls while CPU bound tests are still found to be minimally impacted. When toggling these mitigations on Linux 4.19, Intel Xeon CPUs were found to be 10~15% slower with the default kernel while AMD EPYC CPUs dropped to about 5% slower.

GlobalFoundries has made a major strategy shift announcement. The contract maker of semiconductors says it is ceasing development of bleeding edge manufacturing technologies and stop all work on its 7LP (7 nm) fabrication processes, which will not be used for any client. From a report: Instead, the company will focus on specialized process technologies for clients in emerging high-growth markets. These technologies will initially be based on the company's 14LPP/12LP platform and will include RF, embedded memory, and low power features. Because of the strategy shift, GF will cut 5% of its staff as well as renegotiate its WSA and IP-related deals with AMD and IBM.

GlobalFoundries was on track to tape out its clients' first chips made using its 7 nm process technology in the fourth quarter of this year, but "a few weeks ago" the company decided to take a drastic strategical turn, says Gary Patton. The CTO stressed that the decision was made not based on technical issues that the company faced, but on a careful consideration of business opportunities the company had with its 7LP platform as well as financial concerns. On the heels of this announcement, AMD said today that it will move all of its 7nm production on both CPUs and GPUs to TSMC.

Long-time Slashdot reader Bruce Perens writes: The Register reports that Debian is rejecting a new Intel microcode update because of a new license term prohibiting the use of the CPU for benchmarks and profiling.

There is a new license term applied to the new microcode: "You will not, and will not allow any third party to (i) use, copy, distribute, sell or offer to sell the Software or associated documentation; (ii) modify, adapt, enhance, disassemble, decompile, reverse engineer, change or create derivative works from the Software except and only to the extent as specifically required by mandatory applicable laws or any applicable third party license terms accompanying the Software; (iii) use or make the Software available for the use or benefit of third parties; or (iv) use the Software on Your products other than those that include the Intel hardware product(s), platform(s), or software identified in the Software; or (v) publish or provide any Software benchmark or comparison test results." UPDATE:: Intel has reworked the license to no longer prohibit benchmarking. Imad Sousou, corporate VP and general manager of Intel Open Source Technology Center, tweeted on Thursday: "We have simplified the Intel license to make it easier to distribute CPU microcode updates and posted the new version here. As an active member of the open source community, we continue to welcome all feedback and thank the community."

MojoKid shares a report from Hot Hardware: We been hearing a lot about NVIDA's next-generation GPU architecture since late last year, and today NVIDIA is announcing the first products based on Turing. NVIDIA is targeting the professional graphics market first with its new Quadro RTX 8000, RTX 6000 and RTX 5000 GPUs. Turing GPU architecture replaces Pascal, which has served both the consumer and professional markets since 2016. But as its 8th generation GPU architecture, NVIDIA is ushering in a number of advances with Turing and it's billed as the "world's first ray-tracing GPU." When it comes to content creators, NVIDIA claims that with the power of Turing, "applications can simulate the physical world at 6x the speed of the previous Pascal generation."

Getting down to brass tacks, the entry-level Quadro RTX 5000 has 3,072 CUDA cores, 384 Tensor cores, and will come with 16GB of 14Gbps GDDR6 memory. Its ray-tracing performance is dialed in at 6 GigaRays/sec, according to NVIDIA. Both the Quadro RTX 6000 and RTX 8000 have 4,608 CUDA cores and 576 Tensor cores; the only difference between the two is that the former has 24GB of GDDR6, while the latter doubles that to 48GB. Ray-tracing performance for both of these GPUs tops out at 10 GigaRays/sec. NVIDIA is also claiming up to 16TFLOPs compute performance for the Quadro RTX 8000. NVIDIA's new Quadro GPUs will also be among the first to support both USB-C and VirtualLink for next-generation virtual reality and mixed reality headsets. Other VirtualLink backers include AMD, Oculus, Microsoft and Valve. The Quadro RTX 5000, RTX 6000 and RTX 8000 will all be available during the fourth quarter of 2018 priced at $2,300, $6,300 and $10,000 respectively.

Linus Torvalds wrote of the 4.18 final release: "It was a very calm week, and arguably I could just have released on schedule last week, but we did have some minor updates. Mostly networking, but some vfs race fixes (mentioned in the rc8 announcement as 'pending') and a couple of driver fixes (scsi, networking, i2c). Some other minor random things (arm crypto fix, parisc memory ordering fix)." In a separate article, Phoronix details all the changes and new features available in this release.

A new Intel security flaw has been discovered that potentially allows passwords to be stolen. An anonymous reader quotes Digital Journal: As EE News reports, researchers said the new flaw enables an "inverse spectre attack". According to Giorgi Maisuradze and Professor Dr. Christian Rossow a ret2spec (return-to-speculation) vulnerability with the chips allows for would-be attackers to read data without authorization. According to Professor Rossow: "The security gap is caused by CPUs predicting a so-called return address for runtime optimization."

The implications of this are: "If an attacker can manipulate this prediction, he gains control over speculatively executed program code. It can read out data via side channels that should actually be protected from access." This means, in essence, that malicious web pages could interpret the memory of the web browser in order to access and copy critical data. Such data would include stored passwords.
"At least all Intel processors of the past ten years are affected by the vulnerabilities," reports EE News, adding "Similar attack mechanisms could probably also be derived for ARM and AMD processors...."

"Manufacturers were notified of the weaknesses in May 2018 and were granted 90 days to remedy them before the results were published. That deadline has now expired."

A major virus infection forced the closure of Taiwan Semiconductor Manufacturing Company (TSMC) factories last weekend..." writes Slashdot reader Mark Wilson, noting that it's the largest semiconductor manufacturer in the world, selling chips to Apple, Nvidia, AMD, Qualcomm, and Broadcom, and "responsible for producing iPhone processors."

Now Network World reports: The infection struck on Friday, August 3, and affected a number of unpatched Windows 7 computer systems and fab tools over two days. TSMC said it was all back to normal by Monday, August 6. TSMC did not say it was WannaCry, aka WannaCrypt, in its updates, but reportedly blamed WannaCry in follow-up conference calls with the press.... The company said this incident would cause shipment delays and additional costs estimated at 3 percent of third quarter revenue. The company had previously forecast revenues of $8.45 billion to $8.55 billion for its September quarter. A 3 percent loss would mean $250 million, though actual losses may come out lower than that. Still, that's a painful hit. TSMC also said no customer data was compromised....

TSMC isn't directly to blame here; someone [an infected production tool provided by an unidentified vendor] brought WannaCry into their offices and behind their firewall, but TSMC is still culpable because it left systems unpatched more than a year after WannaCry hit.

An anonymous reader shares a report: AMD has cornered the x86 console market with its handy semi-custom mix of processors and graphics. While we slowly await the next generation of consoles from Microsoft and Sony, today AMD and Zhongshan Subor announced that a custom chip has been made for a new gaming PC and an upcoming console for the Chinese market.

The announcement states that a custom chip has been created for Subor that is based on four Zen cores running at 3.0 GHz and 24 compute units of Vega running at 1.3 GHz. The chip is supported by 8GB of GDDR5 memory, which the press release states is also embedded onto the chip, however it is likely to actually be on the package instead. [...] Assuming that this custom chip is a single chip design, with CPU and GPU, this means that AMD is handily gaining custom contracts and designing custom chip designs for its customers, even for consoles that won't have the mass western appeal such as the Xbox or Playstation.

An anonymous reader writes: "Scientists from the University of California, Riverside (UCR) have published details last week about a new Spectre-class attack that they call SpectreRSB," reports Bleeping Computer. "Just like all 'Spectre-class' attacks, SpectreRSB takes advantage of the process of speculative execution -- a feature found in all modern CPUs that has the role of improving performance by computing operations in advance and later discarding unneeded data. The difference from previous Spectre-like attacks is that SpectreRSB recovers data from the speculative execution process by attacking a different CPU component involved in this 'speculation' routine, namely the Return Stack Buffer (RSB)." In a research paper, academics say they've used SpectreRSB attacks to recover data belonging to other processes, and have even tricked the RSB into spilling SGX secrets. The attack works on Intel, AMD, and ARM processors, known to use RSB. The attack can also bypass all the mitigations put in place for the original Spectre/Meltdown flaws.
