ASUS ROG STRIX B350-I Gaming Motherboard Revealed by Online Retailer

Swedish online retailer Inet has listed an as-yet unannounced ASUS motherboard, the ROG STRIX B350-I-Gaming. It looks to be a smaller version of the ROG STRIX B350-F GAMING, featuring similar black styling, as well as ASUS's AURA Sync RGB lighting technology, in a mini-ITX format. According to Inet, the board features the AMD B350 chipset that is the board's namesake, with AMD AM4 processor support as well as up to 32 gigabytes of DDR4 3200 MHz (OC) RAM. As with most mini-ITX gaming motherboards, a single PCI-Express x16 slot is present for graphics card connectivity. However, belying the board's small size, the B350-I-Gaming features a wealth of connectivity options, including two external USB 3.1 Generation 2 ports as well as four USB 3.1 Generation 1 ports. Additionally, one USB 3.1 Generation 1 header, and even a USB 2.0 header are available internally. Four SATA 6.0 Gbit/s headers, along with two M.2 slots round out the connectivity options, all of which is great for a board this size. Gigabit ethernet as well as built-in wifi, and SupremeFX 8-Channel High Definition Audio are also featured.

While other mini-ITX AM4 motherboards are already on the market, the ASUS ROG brand has a loyal following. ASUS fans looking to build a Ryzen-powered machine with a smaller footprint will no doubt be waiting patiently for an official announcement, as the board is of course listed as Out of Stock on the retailer's site. The amount of connectivity options on such a small board will be a compelling option for portable LAN party machines, and gamers without enough space to house a larger ATX computer, without compromising on storage or speed. Inet has listed the board with a price of 1 899 kr, equivalent to about $233.49 USD. Comparing other product prices on the site with those on Newegg reveals a difference of up to 30%, so regional prices will vary and direct currency conversion is not necessarily a good indicator of local prices.

Intel Core "Coffee Lake" Availability Scarce Until 2018: Report

Intel's 8th generation Core "Coffee Lake" 6-core processors aim to restore the company's competitiveness in the mainstream-desktop (MSDT) platform, which eroded to AMD's unexpectedly successful Ryzen. The chips will hit the stores a little later this month, at price-points very close to the outgoing 7th generation Core "Kaby Lake" processors; although a report by SweClockers predicts that the chips will be scarcely available until early-2018.

Intel is launching "Coffee Lake" desktop processor family with a rather trimmed down lineup of six SKUs, two each under the Core i7, Core i5, and Core i3 brands, with the former two being 6-core, and the Core i3 being quad-core, marking an increase in core-counts across the board. While these chips will very much be available on launch-date in the retail channel, there could be an inventory shortage running all the way till Q1-2018.

G.Skill Releases AMD Ryzen-optimized Trident Z RGB DDR4 Memory

G.SKILL International Enterprise Co., Ltd., the world's leading manufacturer of extreme performance memory and gaming peripherals, announces a new lineup of Trident Z RGB DDR4 memory kits with enhanced compatibility on the latest AMD platforms. Specifically designed for AMD Ryzen and Ryzen Threadripper platforms, now there are vibrant options up to the popular DDR4-3200MHz CL14 or the massive 128GB (8x16GB) kits at up to 2933MHz. For a full range of memory kit capacity options, the new Trident Z RGB memory kit models are available at DDR4-2400MHz in 2-, 4-, and 8-module kit configurations with 8GB and 16GB modules, which allows for 16GB, 32GB, 64GB, or 128GB memory kits for your AMD system.

AMD currently has two platform offerings, where Ryzen supports dual-channel with 2 or 4 memory modules and Threadripper supports quad-channel memory with 4 or 8 memory modules. To give a boost in memory performance to AMD number-crunching workstations and high-end graphic rendering systems, G.SKILL offers several selections for each AMD platform, including memory speeds of up to DDR4-2933MHz or ultra-high capacity at 128GB (8x16GB).

AMD to Build 2nd Gen. Ryzen and Radeon Vega on GloFo 12nm

Not to be held back by silicon fabrication process limitations like in the past, AMD will build its second-generation Ryzen CPUs and Radeon Vega GPUs on the new 12 nanometer LP (low power) FinFET process by GlobalFoundries. From the looks of it, "2nd generation Ryzen" doesn't seem to be the same as "Zen2" (a micro-architectural advancement due to be built on the 7 nm process), and is more likely an optical shrink of existing 14 nm IP to the 12 nm process, giving AMD the headroom to increase yields, and clock speeds across the board. The 12 nm switch allows AMD to roll out a new "generation" of Ryzen processors as early as the first half of 2018.

The "Vega 10" silicon could be another key piece of AMD IP on the receiving end of an optical shrink to 12 nm, which will give AMD much needed power savings, letting it increase clock speeds, and probably implement faster standards of HBM2 memory, such as 2.00 GT/s. AMD will likely label this shrunk down silicon "Vega 20." There's also the possibility of AMD building a bigger new GPUs altogether. In 2019, the company will give its CPU and GPU lineups major micro-architectural upgrades, and the switch to the 7 nm node. The new "Zen2" micro-architecture with IPC increases and new ISA instruction-sets, will be launched on the CPU side, and the new "Navi" graphics architecture will take center-stage.

Noctua Announces Two AM4-compatible Low-profile Coolers

Noctua today presented two updates to its range of quiet low-profile CPU coolers. Successors to the award-winning NH-L9a and NH-L12, the new NH-L9a-AM4 and NH-L12S models now support the AM4 socket of AMD's Ryzen processors. Whereas the NH-L9a-AM4 stands a mere 37mm tall, which makes it ideal for use in compact HTPCs or Small Form Factor cases that offer minimum clearance for CPU coolers, the slightly bigger NH-L12S comes equipped with the new NF-A12x15 PWM fan and combines excellent compatibility, surprising efficiency and remarkable flexibility.

"AMD has made a big impact on the market with its Ryzen architecture and the platform will become even more interesting for compact HTPC builds when the first Ryzen-based APUs are introduced next year," says Roland Mossig (Noctua CEO). "We're thus updating two of our award-winning low-profile models to support Ryzen's AM4 socket."

GeIL Intros Super Luce RGB Lite DDR4 Memory

GeIL today introduced the Super Luce RGB Lite DDR4 memory series. These modules are practically identical to the Super Luce RGB Sync, which the company launched earlier this month, with a few key differences. The Super Luce RGB Lite lacks software-based RGB LED management, and has a preset combination of multi-color lighting that's put out from its diffuser. It lacks any cabling to the RGB header of your motherboard or RGB controller. This is in contrast to the Super Luce RGB Sync, which comes with a thin RGB cable, and supports software such as ASUS Aura Sync, giving you control over the lighting.

Under the illuminated heatspreaders, however, the Super Luce RGB Lite is identical to its sibling. Available in speeds ranging from DDR4-2133 to DDR4-3000, these modules come in densities of 4 GB, 8 GB, and 16 GB, making up single-module and dual-channel kits of 4 GB, 8 GB (2x 4 GB), 16 GB (2x 8 GB), and 32 GB (2x 16 GB). There are also AMD Edition variants of these modules, which are individually tested by GeIL to work at their advertised speeds with AMD Ryzen processors. The modules are backed by lifetime warranties, and are expected to be about 10 to 15 percent cheaper than comparable Super Luce RGB Sync kits.

AMD Ryzen Threadripper MCM De-lidded and De-packaged

PC enthusiast Der8auer, with access to a Ryzen Threadripper processor, took it completely apart for science. It won't be the first time that a Threadripper HEDT processor was de-lidded (its integrated heatspreader removed), revealing that it has four "Zeppelin" 8-core dies, making it practically identical to AMD's 32-core Epyc processors; however, it's the first time that someone completely removed the dies from the package.

Ryzen Threadripper processors are built by completely disabling two out of four "Zeppelin" dies on an Epyc multi-chip module (MCM). Two diagonally opposite dies are disabled. The disabled dies can't be reenabled, at least not on an X399 chipset motherboard, as the Threadripper HEDT platform lacks DRAM, PCIe, and possibly even power wiring for the disabled dies.

On The Story of AMD's Ryzen Threadripper Product Development

In a Forbes interview conducted by Anthony Leather, AMD officials Senior Vice President and General Manager Jim Anderson, Corporate Vice President of Worldwide Marketing John Taylor, Sarah Youngbauer of AMD's communications team, and James Prior, AMD's Senior Product Manager, have shed some light on the development process for AMD's equivalent of a flash hit - their HEDT, HCC Threadripper chips. Threadripper, which leverages AMD's Zen architecture used in their Ryzen and EPYC processors, makes use of an MCM design with up to 16 cores and 32 threads, with AMD's svelte Zen, 8-core base units linked through the company's high speed interconnect Infinity Fabric.

This has allowed the company to scale designs from four core processors with Ryzen 3, all the way towards the current cream of the crop Threadripper 1950X. It's an extremely scalable design, which brings with it improved yields and some pretty significant cost savings for AMD due to smaller dies. This, in turn, means the company is able to more agressively price their Ryzen and Threadripper processors compared to the competition, at least when it comes to high core and thread counts for the same price bracket - and the success of that business decision is showing.

AMD Releases the Ryzen Threadripper 1900X Eight-core HEDT Processor

AMD today released the Ryzen Threadripper 1900X eight-core HEDT (high-end desktop) processor. This product is targeted at pro-sumers who could use the quad-channel memory bandwidth and added I/O which the Threadripper HEDT platform brings to the table, but can make do with 8 cores/16 threads, which is why the chip is priced just $50 higher than the 8-core/16-thread Ryzen 7 1800X, at USD $549. The Threadripper 1900X comes with higher clock speeds than the 1800X, with 3.80 GHz nominal clock-speed (compared to 3.60 GHz of the 1800X), 4.00 GHz boost, and XFR adding another 200 MHz to the boost clock, if your cooling is good enough.

The Ryzen Threadripper 1900X gives you the full quad-channel DDR4-3200 memory interface, with support for up to 2 TB memory, and ECC support. There's even unofficial RDIMM support. The chip also offers the full 64-lane PCI-Express interface, with the same PCI-Express device configurations as the higher 1920X and 1950X parts. AMD created the 1900X by disabling two cores per CCX in each of the active 8-core dies on the Threadripper MCM. The chip also only features 16 MB of L3 cache, that's 4 MB per active CCX. Its TDP continues to be rated at 180W. AMD put out its internal testing performance numbers for the 1900X.

AMD Resolves Linux Marginality Performance Issue on Newly Shipped Ryzen CPUs

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.

Zen Meeting Vega in AMD "Raven Ridge" APU Confirmed

It looks like AMD will combine its two latest intellectual properties, the "Zen" CPU micro-architecture, and the "Vega" graphics architecture into a single silicon after all, as reports citing leaked OpenCL tables confirm that the company's upcoming Ryzen "Raven Ridge" APU will feature graphics compute units (CUs) based on the "Vega" architecture. It's becoming increasingly clear, that "Raven Ridge" features a "Zen" CCX unit, and a "Vega" based graphics core with up to 12 NGCUs, making up 768 stream processors. The "Zen" CCX talks to the "Vega" graphics core using Infinity Fabric, the same interconnect used between two CCX units on the "Summit Ridge" silicon, and between two "Summit Ridge" dies on the Ryzen Threadripper MCM.

The "Raven Ridge" silicon will hence feature up to 4 CPU cores, with SMT enabling up to 8 threads, up to 8 MB of L3 cache, a "Vega" based graphics core with up to 12 NGCUs making 768 stream processors, a dual-channel DDR4 integrated memory controller, and the same integrated southbridge as "Summit Ridge," featuring two SATA 6 Gb/s ports, and USB 3.0 ports directly from the SoC. In addition, you get a PCI-Express 3.0 x16 interface for graphics, which can be split into two x8 for 2-way multi-GPU. The OpenCL listings speak about two distinct variants, one with 11 NGCUs, and another with 8. AMD plans to roll out the first "Raven Ridge" based products as Ryzen 5 series and Ryzen 7 series mobile APUs, with a desktop debut a little later.

Alphacool Presents the Eisblock Flatboy Waterblock for Socket TR4 Systems

Alphacool has been growing their product portfolio immensely as of late, and now, the company is teasing the Eisblock Flatboy, the company's specifically-designed waterblock for AMD's Ryzen Threadripper CPUs. Threadripper CPUs have one of the biggest surface areas ever encountered in a consumer processor; because of that, not all cooling solutions are appropriate to cool the up-to 16 cores and 32 threads monsters, with a higher surface area than normal being needed.

Still in the prototype phase, the Eisblock Flatboy integrates a reverse, silent flow pump system, like the company has already introduced on their Eiswolf product. The prototype as is seems to obstruct clearance for the rightmost DIMM slot to the left of the CPU socket, which shouldn't pose a problem for some people, but would be an extremely sore point for prospective buyers should that design decision overflow towards the final version.

G.SKILL Announces New DDR4 Specifications for AMD Ryzen Threadripper

G.SKILL International Enterprise Co., Ltd., the world's leading manufacturer of extreme performance memory and gaming peripherals, announces all-new DDR4 specifications and expanding the Flare X series, designed for AMD processors and platforms. Compatible with the new Ryzen Threadripper processors and AMD X399 chipset motherboards, these new DDR4 specifications are designed to achieve high frequency at DDR4-3600 MHz 32GB (8GBx4), as well as a massive total capacity at DDR4-2933 MHz 128GB (16GBx8). Included in the mix of new quad-channel DDR4 memory kits are DDR4-3200 MHz CL14 32GB (8GBx4) and DDR4-3466 MHz CL16 32GB (8GBx4).

With improved overclocking performance on the latest AMD Ryzen Threadripper processors on the X399 chipset, G.SKILL is announcing the DDR4-3600 MHz CL16-18-18-38 with 32GB (8GBx4) total capacity running in quad-channel mode, under the Flare X series. Tested for maximum stability, this kit's frequency speed marks the fastest memory kit ever released thus far for an AMD platform.

AMD Ryzen Threadripper "Summit Ridge" Dies are Heavily Binned

AMD revealed that the pair of 8-core "Summit Ridge" dies that make up the Ryzen Threadripper multi-chip module are heavily binned. AMD hand-selects the top-5% highest performing "Summit Ridge" dies for Ryzen Threadripper manufacturing, which makes these chips of a higher grade than even what AMD sets aside for Ryzen 7-series socket AM4 chips.

AMD requires the highest grade "Summit Ridge" dies to use in Threadripper chips, to keep electrical leakage to the minimum, so the chips can run as cool as possible, with the least power-draw. Choosing the best dies could also ensure that Threadripper chips have the highest overclocking-headroom taking into account other electrical and thermal constraints. A 7-series chip such as the 1800X could still achieve higher clocks than a Threadripper chip, in that sense.

Arctic Announces FREEZER 33 TR Cooler for AMD Ryzen Threadripper

Update: Corrected socket compatibility. This is a specially-designed cooler by Arctic for AMD's HEDT platform, As such, it offers limited compatibility with CPUs of lower die sizes, which means it's only compatible with TR4, AM4, LLGA2011(v3) and LGA2066 sockets.

Arctic announced the Freezer 33 TR, a tower-type CPU air cooler, designed for AMD Ryzen Threadripper processors, with out of the box support for AMD socket TR4/SP3r2. The cooler comes in two variants based on color - black with red accents, and black with silver accents. The cooler features a conventional tower-type design, in which four 6 mm-thick copper heat-pipes, which make direct contact with the CPU at the base, pass through an aluminium fin-stack, which is ventilated by an included fan.

Compared to other Freezer 33 variants, the TR variant features an elongated base, for higher coverage of the Threadripper integrated heatspreader (IHS). The aluminium fins and heat-pipes feature matte-black nickel-plating. The included fan takes in 4-pin (PWM) input, spinning between 200 to 1,800 RPM. The cooler can cope with thermal loads of up to 320W, which makes it good for CPU TDP rating up to 200W, according to Arctic. Besides socket TR4, the cooler also supports AMD's AM4 socket, while Intel support stands at their LGA2011(v3), LGA2066. Available now, and backed by a generous 10-year warranty, the Freezer 33 TR is priced at 47.99€.

Thermaltake Announces Ryzen Threadripper Support for Water 3.0 Riing AIO Coolers

Thermaltake today announced that five of its Water 3.0 Riing series all-in-one, closed-loop, liquid CPU cooler models support AMD Ryzen Threadripper processors in the new TR4 package. Among the supporting models are the Water 3.0 Riing RGB 360, Water 3.0 Riing RGB 240, Water 3.0 Riing RGB 120, Water 3.0 Riing RGB Extreme, and Water 3.0 Riing RGB Ultimate. The five coolers include brackets for socket TR4, although the company didn't mention if the circular blocks of the Water 3.0 Riing RGB series provides 100% coverage of the processors' integrated heatspreader.

AMD Ryzen Threadripper 1950X Overclocked to 4.1 GHz With Liquid Cooling

Redditor "callingthewolf" has posted what is an awe-inspiring result for AMD's Ryzen Threadripper 1950X (that's an interesting username for sure; let's hope that's the only similarity to the boy who cried wolf.) The 16-core, 32-thread processor stands as the likely taker for the HEDT performance crown (at least until Intel's 14-core plus HEDT CPUs make their debut on the X299 platform.) With that many cores, highly thread-aware applications naturally look to see tremendous increases in performance from any frequency increase. In this case, the 1950X's base 3.4 GHz were upped to a whopping 4.0 GHz (@ 1.25 V core) and 4.1 GHz (at 1.4 V core; personally, I'd stick with the 4.0 GHz and call it a day.)

The feat was achieved under a Thermaltake Water 3.0 liquid cooler, on a non-specified ASRock motherboard with all DIMM channels populated with 8 x 8 GB 3066 MHz DIMMs. At 4.0 GHz, the Threadripper 1950X achieves a 3337 points score on Cinebench R15. And at 4.1GHz, the big chip that can (we can't really call it small now can we?) manages to score 58391 points in Geekbench 3. While those scores are certainly impressive, I would just like to point out the fact that this is a 16-core CPU that overclocks as well as (and in some cases, even better than) AMD's 8-core Ryzen 7 CPUs. The frequency potential of this Threadripper part is in the same ballpark of AMD's 8-core dies, which speaks to either an architecture limit or a manufacturing one at around 4 GHz. The Threadripper 1950X is, by all measurements, an impressively "glued together" piece of silicon.

BYKSKI Showcases First Water Blocks for Ryzen Threadripper

Chinese liquid-cooling manufacturer BYKSKY has showcased what are as of yet the first waterblocks specifically engineered for AMD's HEDT X399 platform. The company has showcased a grand total of four variants for their liquid-cooling solutions, which come with accents in either Red, Silver, Red + RGB Lighting, or Silver + RGB Lighting.

Sans RGB, the blocks are expected to retail for about $58; adding a light spectacle to your water blocks, however, will seemingly increase pricing to a still very appealing $63. Even though these specific Threadripper waterblocks are for now only listed in China, expect availability to expand in the coming weeks.

AMD Confirms Ryzen Marginality Performance Issue Under Linux, TR and EPYC Clear

An issue on AMD's Ryzen performance under certain Linux workloads, which caused segmentation faults in very heavy, continuous workloads on the Ryzen silicon (parallel compilation workloads in particular) has been confirmed by AMD. Tests like Phoronix's Test Suite's stress run quickly bring the Ryzen processors to their knees with multiple segmentation faults. While this problem is easy to cause under very heavy workloads, the issue is virtually absent under normal Linux desktop workloads and benchmarking,

AMD also confirmed this issue is not present in EPYC or Threadripper processors, but are isolated to early Ryzen samples under Linux (AMD's testing under Windows has found no such behavior.) AMD's analysis has also found that these Ryzen segmentation faults aren't isolated to a particular motherboard vendor, but are problems with the processors themselves. AMD encourages Ryzen customers who believe to be affected by the problem to contact AMD Customer Care. Some of those who have contacted customer care about the segmentation faults have in turn been affected by thermal, power, or other problems, but AMD says they are committed to working with those encountering this performance marginality issue under Linux. AMD will also be stepping up their Linux testing/QA for future consumer products.
