Researchers at UC Berkeley and UC Riverside have developed a new, ultrafast method for electrically controlling magnetism in certain metals, a breakthrough that could lead to greatly increased performance and more energy-efficient computer memory and processing technologies. The findings of the group, led by Berkeley electrical engineering and computer sciences (EECS) professor Jeffrey Bokor, are published in a pair of articles in the journals Science Advances (Vol. 3, No. 49, Nov. 3, 2017) and Applied Physics Letters (Vol. III, No. 4, July 24, 2017).

Computers use different kinds of memory technologies to store data. Long-term memory, typically a hard disk or flash drive, needs to be dense in order to store as much data as possible. But the central processing unit (CPU) - the hardware that enables computers to compute - requires its own memory for short-term storage of information while operations are executed. Random Access Memory (RAM) is one example of such short-term memory.

Watercool started development on their waterblocks for AMD Threadripper processors back in August. The brand made an announcement today on their Facebook stating that waterblocks are ready to come out of the oven. The Heatkiller IV waterblocks will come in three variants: copper, nickel, and nickel/black. All three models are available for preorder tomorrow. If you're quick enough to pull the trigger, you can also net yourself a nice 10% preorder discount. According to Watercool, the copper model ships on November 10th, while the other two remaining nickel models will start shipping on November 24th.

The full copper model is a waterblock aimed at copper lovers. It comes with an unique, huge Threadripper cooling plate made entirely of copper. The massive top is milled out of one solid block of copper. On the other hand, the nickel block caters to those who prefer a more glossy look. Both the huge cold plater and top are milled out of solid copper; then consequently nickel plated. Lastly, Watercool calls the nickel/black model the jack of all trades. The copper cold plate is nickel plated, while the top is manufactured from acrylic (Plexiglas GS) and comes with a black anodized aluminum cover. RGB lighting is present thanks to the preinstalled RGB LED strip which connects to the RGB LED headers on X399 motherboards through a black, paracord sleeved cable.

In an interview with Bit-tech, ASUS ROG motherboard product manager Andrew Wu has let the proverbial cat out of the bag: apparently, compatibility of Z270 boards with Coffee Lake processors wouldn't have been impossible after all. When asked why the new Coffee Lake CPUs aren't compatible with the previously released Z270 platform, Andrew Wu explained that it" (...) depends on Intel's decision." Andrew Wu also went on to mention that Intel's stated power delivery reasons don't "make much difference", and that ASUS themselves could make their Z270 motherboards compatible with Coffee Lake. For that, however, they'd need "(...) an upgrade from the ME [Management Engine] and a BIOS update", for which "Intel somehow has locked the compatibility."

It seems all of that extra "pin-count" doesn't really matter in the grand scheme of the current Coffee Lake lineup with up to six core processors - the CPU socket and platform as designed with Z270 would have been able to handle the increased core counts and power loads. The question gets murkier with Intel's ability to release an 8-core CPU to the Z370 platform though - that particular amount of cores might indeed prove to be too much for Z270's power delivery. Making an educated guess, it would seem that Intel could have allowed for Coffee Lake compatibility on Z270 motherboards on CPUs up to 6 cores, but would need the new revisions on the Z370 platform to allow for operation of 8-core Coffee Lake chips.

This here is an issue that this editor has been fearing for a while, and that we here at TPU have called our users' attention to in the past. It's bad enough when websites willingly implement web mining scripts absent of users' consent or simple knowledge. Opt-in mining as a contribution to a website's revenue would be the best way to go around the issue; however, absent that, a simple opt-out capability wouldn't be much worse. But if stealth usage of a site viewers' computing resources is bad, what then can be said when the site managers themselves are unaware of the implementation of a web miner?

This is what happened with Politifact, the US politics fact-checking website, which is but one of hundreds of the world's top traffic websites that have seen the stealth introduction of these web mining scripts - against the will of the site managers. In the meantime, Politifact has brought down the offending code and has vowed to investigate, but this opens up Pandora's box, really. Generally speaking, these JavaScript apps are running code hosted on another server that the end user - and sometimes even the site hosts - can't inspect or don't expect to have to inspect. And this is easier to do than one would imagine; there's a lack of protection against JavaScript routines like this one. And where there's potential for profit, there's abuse; and that's what we're seeing. It also doesn't help that injecting the necessary JavaScript into the front page of a website is much easier than a full blown hack into a website's databases; and once the code has been shoehorned into a website's code, it runs itself, hijacking users' CPU cycles and putting the resulting Monero coins into a designated wallet.

Intel is no longer going to disclose all-core Turbo Boost speeds, starting with their 8th Gen Coffee Lake processors that have just been released. The information comes straight from the blue giant. Answering a query from ExtremeTech on the matter, the company said that "[W]e're no longer disclosing this level of detail as its proprietary to Intel. Intel only specifies processor frequencies for base and single-core Turbo in our processor marketing and technical collateral, such as ARK, and not the multi-core Turbo frequencies. We're aligning communications to be consistent. All Turbo frequencies are opportunistic given their dependency on system configuration and workloads."

This decision is a rollback that does little more than rob users of another data point that has really always been there. The practical effect of this change isn't anything to write home about: Intel's Turbo Boost capabilities were never guaranteed performance levels (the fact that the advertised Turbo speeds were called "Max Turbo" implied Turbo levels could be lower.) However, there's also not much that can be said to explain this change in stance from the blue giant. If anything, this decision only opens up debate and speculation regarding the reasons why Intel is making this change: and the skeptics among us will always default to foul play or dark linings.To our Forum dwellers: this piece is marked as an Editorial

We've previously covered The Pirate Bay's usage of a web-based miner on users' machines without their knowledge or consent. We've even done a pretty extensive editorial on whether or not this could be the revenue model of the future. At the time, we came away with the conclusion that the problem isn't with the technology per se, but with the fact it's implemented by humans (and most problems do have their root cause in us humans after all, don't they?).

This seems to be such a case, since The Pirate Bay has now resumed their web-based mining activities with no Opt-out or, better yet, opt-in business model. Now, however, the code isn't being run in the site's core code, but is instead embedded on an advertisement script (yes, advertisements are still running parallel on The Pirate Bay). The most popular adblockers should be enough to stop this miner from ever running, anyway, but yes, there are still users who surf the web absent of any ad-blocking capabilities - and these should see some added processing spikes on their CPUs.

Intel is set to release its newest generation of processors, known as code name Coffee Lake in just a few days. Recent controversy has focused around the inability of newer processors to be used with motherboards supporting the previous generation CPUs. Intel has released data sheets for Coffee Lake CPUs, and images of the socket's layout support Intel's statement that Coffee Lake will indeed need a new socket design. Specifically, there are more pins responsible for delivering the main power for the CPU cores, known as VCC pins, with Coffee Lake motherboards sporting 146 VCC pins illustrated in the first image below, compared to Kaby Lake and Skylake's 128 illustrated in the second image.

With these pins responsible for delivering power to the CPU cores, this may suggest that previous generation motherboards allowed for lower power operation than is possible with the higher core count of Coffee Lake processors. Whatever the reason, it definitely confirms that Coffee Lake CPUs are hardware-incompatible with previous generation motherboards, and not simply a software or BIOS-level lock.

A recent AMD roadmap leak showed the company's "tick", process-improved plans for 2018's Zen+, as well as its painter-imbued aspirations with Zen 2 in 2019. Now, there's some new info posted by DigiTimes that's being sourced straight from motherboard makers that points to the company's Pinnacle Ridge launch being set sometime in February 2018.

This information seems to have been delivered to the motherboard makers straight from AMD itself, as a heads-up for when they should be expecting to ramp up production of next-generation chipsets. Sources report that AMD will follow their Summit Ridge, Ryzen launch, with the initial release of Pinnacle 7 in February, followed by the mid-range Pinnacle 5 and entry-level Pinnacle 3 processors in March 2018. DigiTimes also reports that AMD is expecting to see its share of the desktop CPU market return to at least 30% in the first half of 2018 which, coeteris paribus, is more of a simple mathematical progression than clarvoyance.

IBASE, a global leader in the manufacture of embedded computing and IIoT solutions, launches its new IB990 PICMG 1.3 full-size CPU card. The board supports the latest 7th/6th Generation Intel Xeon/Core i7/i5/i3 processors with speeds up to 4.0GHz. Based on the chipset family formerly known as Skylake, Intel C236 and Q170 Express chipsets, the high-performance IB990 SBC is built with two DIMM sockets to support DDR4 2133 MHz memory modules with up to 32GB in total and six superfast SATA III ports featuring RAID 0/1/5/10 and 6 Gb/s speed.

As a perfect solution for control systems in factory automation and other industrial applications, IB990 is designed for compute, data and graphics intensive applications and enables up to three independent displays via DVI-I, VGA and DVI-D interface. This long-life single board computer incorporates a rich set of I/O connectivity including two Gigabit Ethernet, four COM, two USB 2.0 and three USB 3.0 ports, plus a Mini PCI-E expansion socket for optional wireless modules. Additionally, the IB990 takes advantage of Intel AMT 11.0 for remote management and powering-on functionalities.

Overclocking poster-boy Der8auer has seemingly gotten his hands on some early samples of Intel's Skylake-X high core count (HCC)HEDT CPUs. The upcoming 12 to 18-core enthusiast-class CPUs are being launched on the same X299 platform on socket LGA 2066 that Intel has already launched 4 (Kaby Lake-X), 6, 8 and 10-core parts already, and are supposed to bring Intel towards a level playing field - and then some - with competitor AMD's Threadripper CPUs, which boast of up to 16 cores.

From this delidding process with Der8auer's own delidding tool, Delid-Die-Mate-X, seems to result a die that is much larger - as expected - than Intel's 10-core i9-7900X. At the same time, it seems that Intel is still opting, again, for not soldering its enthusiast-targeted CPUs, which would result in better temperatures and, potentially, overclocking potential. The fact that Der8auer managed to delid the i9-7920X and didn't recommend against doing it likely means that there is minimal risk of damaging your CPU while subjecting it to this process. This is something the renowned overclocker did do when he recommended that users shouldn't delid their Ryzen or Threadripper CPUs looking for better temperatures, since the fact that these were soldered would likely result in both catastrophic damage and a much diminished chance of operating temperatures improvement through the application of special purpose thermal compounds. The Facebook post from Der8auer with the delidded 7920X likely serves as an appetizer for an upcoming delid video on YouTube, as has been the overclocker's MO.

At its pre-launch media conference call for the Ryzen Threadripper 1900X, AMD mentioned that the chip has been carved out from the common 4-die EPYC MCM using a "4-0-4-0 diagonal configuration," which led to some confusion as to which cores/dies AMD disabled to carve out the $549 8-core HEDT processor. The company shed some light on this matter, responding to questions from TechPowerUp.

It turns out, that the Threadripper 1900X features an entire CCX (quad-core CPU complex) disabled per active die on the multi-chip module, so the CCX that's enabled has 8 MB of L3 cache; and access to the die's entire uncore resources, such as the dual-channel memory controller, PCIe root complex, etc. With two such active "Zeppelin" dies, the Threadripper 1900X ends up with 8 cores, 16 MB of L3 cache, a quad-channel memory interface, and 64 PCIe lanes.

Building on the global enthusiasm generated by the launch of Ryzen high-end desktop processors and EPYC server processors for the datacenter, AMD (NASDAQ: AMD) today announced broad adoption of enterprise solutions featuring AMD Ryzen PRO desktop processors. Designed for business, Ryzen PRO processors bring reliability, security, and performance to address the demands of today's compute-intensive enterprise-focused workloads. Commercially-focused desktop solutions based on these new processors are expected to be available from Dell, HP, and Lenovo in the coming weeks.

"Today's business PC users require more processing power than ever before to run increasingly demanding applications, to ensure they can multi-task without disruption, and to help protect against security threats," said Jim Anderson, senior vice president and general manager, Computing and Graphics Group, AMD. "Ryzen PRO is designed to address these needs, and we're proud to collaborate with such a strong set of industry leaders on a robust assortment of AMD-based desktop PCs that showcase the strength and flexibility of the Ryzen PRO platform."

We've brought to your attention how AMD's Ryzen architecture was encountering a bug that prevented it from successfully performing certain tasks under Linux. The issue, to which Phoronix was the first website to call attention to, was later confirmed by AMD, with a further remark from the chip designer that EPYC and ThreadRipper weren't affected by it.

AMD has now solved the Ryzen issue at a silicon level, and new revisions of the CPUs should be clear of the problems. Phoronix's Michael Larabel has confirmed that the new processor passes the previous insurmountable, crash-prone workloads with flying colors, so all in all, AMD delivered a swift response to the issue. The company is also doing good for itself in that it is open to replacing previous-batch CPUs that are affected by the issue, through a contact to its Customer Care department.

Intel has just opened the proverbial lid on their 8th Gen "Coffee Lake" family of CPUs, which should bring about a democratization of cores for the masses. Acer has been quick to jump on the 8th Gen bandwagon, by announcing their new Nitro 5 Spin laptop, which brings with it the increased performance and "UHD graphics" of Intel's 8000 series of CPUs.

The Nitro 5 Spin is being marketed as a convertible, gaming-focused laptop, whose 15.6 1920*1080 IPS panel can be rotated to multiple locking positions through a 360º hinge. The gaming part of this laptop seems a little subdued - an NVIDIA GTX 1050 graphics card is confirmed to be on board - while memory configuration, and even the specific Intel 8th Gen processor inside, are still a mystery. The company also said that 802.11ac MU-MIMO Wi-Fi will be par of the course for their new offering, and that we should expect this take on Intel's 8th Gen mobility CPUs to be available sometime in October, for a respectable $999.

Like many other manufacturers, Fractal Design isn't sleeping under the proverbial palm tree with their products. They too have sought to keep after the most promising high performance platforms for their Celsius AIOs, and have announced compatibility with Intel's latest X299 platform and AMD's X399. The S24 is one of the best 240 mm AIO coolers out there, apparently; models of this lineup feature a 12 V ceramic bearing water pump equipped with a copper cold plate. The Celsius line of coolers also come equipped with an integrated fan hub that allows end users to plug the cooler fans directly into the radiator instead of the motherboard - leaving those fan headers free for other pieces of hardware.

The compatibility will be achieved, as usual, through a separate bracket. AMD Threadripper users will be able to rest assured, since their purchase of a Threadripper CPU will already come with a Asetek retention kit inside the box (compatible with Fractal Design's coolers, naturally.) Intel X299 users will find full compatibility for the socket via the included 2011-v3 kit inside the Fractal Design Celsius AIO packaging.

There are two kinds of desktop CPU platforms. The mainstream tier runs from two cores up to eight, and it's great for gaming and general use. Its high-end sibling takes everything up a level with more cores, more memory channels, and more bandwidth for graphics and storage. A considerable upgrade in every regard, this high-end desktop platform appeals to power users, content creators, and prosumers who want to blur the line between desktop and workstation. AMD's Threadripper CPU is the latest addition to the desktop's heavyweight division, and it walks into the ring with an entourage of SocketTR4 motherboards in tow. This guide explains the ASUS and ROG family to help you pick the best X399 motherboard for your high-end desktop or gaming PC.

All of our X399 boards share core DNA that includes one-touch overclocking, refined cooling control, and improved RGB lighting. Yet they each have their own distinct flavor as well. The ROG Zenith Extreme brings Threadripper into the world of premium dream PCs with provisions for custom liquid cooling and 10G networking. With the Strix X399-E Gaming, hardcore gamers can build stylish rigs with power to spare for high-quality streaming. And then there's the Prime X399-A and its well-rounded foundation channeling the professional side of the platform's prodigious power. Which X399 motherboard should you buy for your build? Let's find out.

It has been a huge weekend of product announcements and launches from AMD, which expanded not just its client computing CPU lineup on both ends, but also expanded its Radeon graphics cards family with both client- and professional-segment graphics cards. This article provides a brief summary of everything AMD launched or announced today, with their possible market-availability dates.

BIOSTAR RACING and PRO series motherboards offer one of the widest selection of AM4 motherboards for Ryzen 3, 5, 7, Bristol Ridge and 7th Generation A-series. Gamers looking to take full advantage of the affordable AMD quad-core CPUs can select from BIOSTAR's RACING X370 series: RACING X370GTN, RACING X370GT7, RACING X370GT5 or RACING X370GT3. While anyone aiming to build a value and performance system can select from BIOSTAR's RACING B350 series: RACING B350GTN, RACING B350GT5, RACING B350GT3 and RACING B350ET2 and PRO B350 and A320 series: TB350-BTC, TA320-BTC, A320MH PRO and A320MD PRO.

AMD did not just announce retail availability on Ryzen Threadripper today, they also had some on-site and arranged for a fun LN2 overclocking event as part of Capsaicin SIGGRAPH 2017. As always, such events are to give day one estimates on the maximum performance potential of the silicon which in turn guides end users and board partners alike on the worst case scenarios as far as power draw and cooling requirements go.

Monstru from Lab501 was kind enough to share a couple of pictures of the actual event with us while AMD followed up with a Cinebench R15 screenshot as seen below. All 16 cores of the Ryzen Threadripper 1950X were overclocked to 5.2 GHz with a x52 multiplier on a standard 100 MHz bus speed. Core VID from CPU-Z is not trustworthy at these temperatures, so presumably it was more in the range of 1.6 V than 1.16 V. They did have DDR4 RAM in quad channel but at the JEDEC base of 2133 MHz to get as high a CPU frequency without the IMC being a factor. The Cinebench R15 score of 4122 cb is very impressive, given the previous high score for a 16-core CPU was 2867 cb, and it took a 28 core CPU to beat this score before. Sure, the days of high core count overclockable CPUs is only coming now but it goes to show where we were before AMD and Intel both decided to go big this generation.After the break we have some photographs of X399 motherboards from various manufacturers, so be sure to take a look.

It seems that previous rumors of AMD bundling a water cooling solution with their premium HEDT Threadripper line of CPUs both were and weren't quite close to the mark. It appears that no, there won't be a liquid cooling solution shipped with the high-performance, high core-count processors after all - as a quick look at the leaked Threadripper retail packaging might convey due to the laws of physics and size constraints.

Even so, it seems AMD will be shipping a solution for water cooling of sorts... By including an Asetek-compatible retention kit with their retail packages of Threadripper. Asetek's designs are shipped under the company's own brand, as well as in a number of recognized, high-quality brands, such as NZXT's Kraken series, EVGA's CLC Series, and some of Corsair's coolers (such as the H100iV2 and the H115i coolers.) Though with Threadripper's IHS's giant size, it is likely that most water cooling solutions currently on the market won't have a sufficiently-sized base plate to cover the entire IHS area. Effects of this on cooling performance remain to be seen, though it probably won't improve temps.

After a CPU-Z screenshot leaked of Intel's upcoming Coffee Lake hexa-core CPUs, which look to bring the fight to AMD's Ryzen, this time there are leaks of three different Intel 6-core processors. The previous CPU-Z screenshot apparently pointed towards Intel's upcoming 8700K six-core processor, with a base clock of 3.5 GHz and a boost clock of 4.3 GHz. The BCLK of the CPU was set at 100 MHz with a TDP of 80W.

In the new leak, the i7-8700K seems to have received a speed bump and accompanying TDP increase. It now sits at a reported 3.7 GHz base clock, 4 GHz boost for four and six cores, 4.2 GHz for dual-core workloads, and 4.3 GHz for single-core workloads under a 95 W TDP. The second leaked six-core processor still sits at that 95 W TDP, but has much lower core clocks than the purported 8700K: a 3.2 GHz base clock with 3.4 GHz boost for four and six cores, and a 3.6 GHz boost for one or two-core workloads. Both of these appear to be unlocked, overclockable chips (IA Overclock capable.) The last CPU in this leaked info is a 65 W chip whose clocks seem a little out of the other's league. It has a lower base clock of 3.1 GHz, granted, but a four and six core turbo up to 3.9 GHz. Dual core boost stands at 4.1 GHz, while single-core workloads see Turbo taking the ship up to 4.2 GHz. The lower base clocks and increased Turbo speeds mean that this is likely an i7 T series chip. Naturally, you should take this information with a bucket of salt.

We recently covered how users with systems powered by Intel's Clover Trail CPUs were having issues with a "Windows 10 is no longer supported on this PC" error when trying to update their machines to Microsoft's latest Windows 10 Creators Update. The systems in question - built around Intel's Clover Trail Atom processors - are generally low-cost, low-power machines (mainly 2-in-1) released between 2012 and 2015 under Windows 8 and 8.1. These systems were deemed ready to receive Windows 10; however, now it looks as if they won't ever be able to support it.

In our last piece, we wondered if this problem was only temporary; now it seems it's permanent. Microsoft has however announced that Clover Trail-based systems will still receive security updates (just not feature updates) until 2023. The issue seems to lay with Clover Trail's integrated GPU drivers; Clover Trail Atoms use GPU technology licensed from Imagination Technologies. Ars Technica's Peter Bright says that "Imagination appears unwilling, and Intel appears unable, to update the GPU drivers to meet the demands of the Creators Update. So systems built with such hardware will never be upgradable beyond the Anniversary Update."

Over at Techspot, Steven Walton managed to get a hold of Intel's new six-core, 12-thread Core i7-7800X CPU, and chose to take it for a spin over a levy of gaming benchmarks. The results don't bode particularly well for Intel's new top i7 offering, though: it is soundly beat by its smaller, svelter brother in virtually all gaming tasks.

Out-of-the-box results are somewhat in line with what we would expect: the Core i7-7700K does bring about a base clock increased by 700 MHz compared to the i7-7800X (4.2 GHz vs 3.5 GHz), and has a higher boost clock to boot (4.5 GHz vs 4 GHz.) And as we've seen over and over again, including with Intel rival AMD's Ryzen offerings, frequency usually trumps core count when it comes to performance when applications are exposed more than four cores. And this leads to Walton's results: the Core i7 7700K is still king in pure FPS terms, coming in with a much more attractive proposition than the 7800X in both minimum and maximum FPS, as well as power consumption.

In what could be a decisive response from Intel towards AMD's recent Ryzen success and core count democratization, reports are making the rounds that Intel is preparing for a shakedown of sorts of its i7 and i5 CPU line-up under the upcoming Coffee Lake architecture. We recently saw (and continue to see) AMD deliver much more interesting propositions than Intel in a pure power/performance/core ratio. And Intel seems to know that its lineup is in dire need of revision, if it wants to stop its market dominant position from bleeding too much.

A report from Canard PC claims that Intel will thoroughly revise its CPU lineup for the Coffee Lake architecture, with an i7-8700K six-core, 12-thread processor being the top offering. This 8700K is reported to deliver its 12 threads at a 3.7 GHz base clock, and a 95 W TDP. These are comparable to AMD's Ryzen 5 1600X processor, which ships with the same six cores and 12 threads under the same TDP, though it has 100 MHz less in base clock speed. However, AMD's Ryzen 5 1600X does retail for about $249 - and you can go even lower to Ryzen 5 1600's $219 - which probably won't happen with Intel's top of the line i7 offering. A slight mention towards the Ryzen 7's 95 W TDP - the same as this reported i7 8700K - even though it has 2 more physical cores, and 4 extra threads.

Amazon inventory of AMD's Ryzen 7 and Ryzen 5 processors seem to be suffering from RMA fraud, if several reddit reports and a general article from WCCFtech are to be believed. The RMA fraud appears to consist of a scheme in which an unknown party has been buying up quantities of Ryzen 7 or 5 series CPUs, and RMAing them back to Amazon with a fake CPU inside. The fake CPU appears to be an older Intel-based LGA packaged model, ironically.

The RMA gets by because the heatspreader is relabeled with an authentic looking AMD Ryzen label, which is presumably enough to fool a very PC-knowledge limited Amazon RMA check-in employee. This means the product gets sold again as an open-box item, as usually happens with RMAs.
