AMD TRX40 Chipset Not Compatible with 1st and 2nd Gen Threadrippers

AMD is giving finishing touches to its 3rd generation Ryzen Threadripper HEDT processor lineup, and the first wave of these chips, starting with a 24-core model, will launch alongside the AMD TRX40 chipset. It turns out that the chipset won't be compatible with 1st and 2nd generation Ryzen Threadripper processors. The upcoming 3rd generation Threadripper chips won't be backwards-compatible with the AMD X399 chipset, either. We've been hearing from reliable sources rumors of this segmentation from AMD for a few days now, and tech journalist ReHWolution just tweeted its confirmation having obtained info on upcoming motherboards from a leading brand.

The underlying reason between this restriction remains a mystery. We know that the EPYC "Rome" MCM is pin-compatible with first-generation EPYC "Naples" chips due to the fact that the newer chips are drop-in compatible with older servers via a BIOS update. The TR4 socket, too, is nearly identical to SP3r2, but for four out of eight memory channels being blanked out. It remains to be seen if for TRX40 motherboards, AMD re-purposed these unused pins for something else, such as additional PCIe connectivity or more electrical pins. We'll find out in November, when AMD is expected to launch these chips.

MSI Confirms Upcoming TRX40 Platform, Lists Creator TRX40 Motherboard

MSI today inadvertently confirmed preparations for the release of TRX40-based motherboards, which will allow for AMD's next-gen, Zen 2-based Threadripper CPUs to slot in quite nicely in a bed of silicon. Via a promo page for new motherboard purchases, where MSI listed the eligible motherboards for a $25 Steam rebate after purchase, the company listed a number of their already-known motherboard quantities... And the new Creator TRX40. This is a new series of motherboards from MSI, first populated by the X299 motherboards, which caters to expandability and storage capabilities so as to accelerate content creation and production.

The reference to the Creator TRX40 has already been silently deleted in MSI's page.

AMD Updates Roadmaps to Lock RDNA2 and Zen 3 onto 7nm+, with 2020 Launch Window

AMD updated its technology roadmaps to reflect a 2020 launch window for its upcoming CPU and graphics architectures, "Zen 3" and RDNA2. The two will be based on 7 nm+ , which is AMD-speak for the 7 nanometer EUV silicon fabrication process at TSMC, that promises a significant 20 percent increase in transistor-densities, giving AMD high transistor budgets and more clock-speed headroom. The roadmap slides however hint that unlike the "Zen 2" and RDNA simultaneous launch on 7th July 2019, the next-generation launches may not be simultaneous.

The slide for CPU microarchitecture states that the design phase of "Zen 3" is complete, and that the microarchitecture team has already moved on to develop "Zen 4." This means AMD is now developing products that implement "Zen 3." On the other hand, RDNA2 is still in design phase. The crude x-axis on both slides that denotes year of expected shipping, too appears to suggest that "Zen 3" based products will precede RDNA2 based ones. "Zen 3" will be AMD's first response to Intel's "Comet Lake-S" or even "Ice Lake-S," if the latter comes to fruition before Computex 2020. In the run up to RDNA2, AMD will scale up RDNA a notch larger with the "Navi 12" silicon to compete with graphics cards based on NVIDIA's "TU104" silicon. "Zen 2" will receive product stack additions in the form of a new 16-core Ryzen 9-series chip later this month, and the 3rd generation Ryzen Threadripper family.

AMD Readies Three HEDT Chipsets: TRX40, TRX80, and WRX80

AMD is preparing to surprise Intel with its 3rd generation Ryzen Threadripper processors derived from the "Rome" MCM (codenamed "Castle Peak" for the client-platform), that features up to 64 CPU cores, a monolithic 8-channel DDR4 memory interface, and 128 PCIe gen 4.0 lanes. For the HEDT platform, AMD could reconfigure the I/O controller die for two distinct sub-platforms within HEDT - one targeting gamers/enthusiasts, and another targeting the demographic that buys Xeon W processors, including the W-3175X. The gamer/enthusiast-targeted processor line could feature a monolithic 4-channel DDR4 memory interface, and 64 PCI-Express gen 4.0 lanes from the processor socket, and additional lanes from the chipset; while the workstation-targeted processor line could essentially be EPYCs, with a wider memory bus width and more platform PCIe lanes; while retaining drop-in backwards-compatibility with AMD X399 (at the cost of physically narrower memory and PCIe I/O).

To support this diverse line of processors, AMD is coming up with not one, but three new chipsets: TRX40, TRX80, and WRX80. The TRX40 could have a lighter I/O feature-set (similar to the X570), and probably 4-channel memory on the motherboards. The TRX80 and WRX80 could leverage the full I/O of the "Rome" MCM, with 8-channel memory and more than 64 PCIe lanes. We're not sure what differentiates the TRX80 and WRX80, but we believe motherboards based on the latter will resemble proper workstation boards in form-factors such as SSI, and be made by enterprise motherboard manufacturers such as TYAN. The chipsets made their way to the USB-IF for certification, and were sniffed out by momomo_us. ASUS is ready with its first motherboards based on the TRX40, the Prime TRX40-Pro, and the ROG Strix TRX40-E Gaming.

AMD "Sharkstooth" Shows Up on Geekbench: Possible Zen 2 Threadripper

AMD is possibly testing its 3rd generation Ryzen Threadripper HEDT processors, with an interesting entry showing up on the Geekbench online database. The entry speaks of an "AMD Sharkstooth" processor with 32 cores and 64 threads, with a nominal clock speed of 3.60 GHz, and the long-form model number "AuthenticAMD Family 23 Model 49 Stepping 0." None of the 2nd generation EPYC processors correspond with these specs, and so we're almost certain this is a client-segment Ryzen Threadripper part.

The prototyping platform, which is a motherboard designed in-house by AMD to test the processor's various components and I/O capabilities, is codenamed "WhiteHavenOC-CP." In this Geekbench submission, the processor is paired with around 128 GB of memory, and tested on 64-bit Linux. The platform yields a multi-threaded score of 94,772 points, which is about 18.5 percent higher than what a Ryzen Threadripper 2990WX typically manages when tested on Linux. It is also within 5% of what the Xeon W-3175X manages (around 99,000 points). The production model could be clocked higher. AMD will also use the opportunity to launch a new motherboard chipset while maintaining backwards-compatibility with the AMD X399. This new chipset will enable PCI-Express gen 4.0 and come with stiffer CPU VRM and memory/PCIe wiring specifications to enable higher memory clocks and PCIe link stability. AMD is expected to launch its 3rd gen Ryzen Threadripper this October, to preempt Intel's next HEDT processor series.

AMD 3rd Gen Threadripper Coming This October to Take on Intel's New HEDT Lineup?

AMD is planning to surprise Intel by unveiling its 3rd generation Ryzen Threadripper HEDT (high-end desktop) processor lineup around the same time Intel launches its 10th generation Core "Cascade Lake-X" processor and the "Glacial Falls" HEDT platform, according to sources in the motherboard industry, speaking with DigiTimes. We're fairly sure the sources aren't referring to AMD's 16-core Ryzen 9 3950X processor, because it has already been announced and will be available in September.

The 3rd generation Ryzen Threadripper will likely be a derivative of the company's "Rome" multi-chip module, and compatible with existing socket TR4 motherboards with a BIOS update, although a new chipset could also be launched to enable PCI-Express gen 4.0. AMD has the option to deploy up to 64 CPU cores across eight 7 nm "Zen 2" chiplets, while the 12 nm I/O controller die will be likely reconfigured for the HEDT platform with a monolithic 4-channel DDR4 memory interface and 64 PCIe gen 4.0 lanes. It's capable of 8 memory channels on the 2nd generation EPYC.

ASUS Expands ROG Strix LC Lineup with a 360mm Model

ASUS today expanded its ROG Strix LC line of all-in-one liquid CPU coolers with a new top variant that comes with a large 360 mm x 120 mm radiator for better cooling. The ROG Strix LC series had debuted in May with 120 mm and 240 mm variants. ASUS bundles three of the same 120 mm fans it includes with the pricier Ryuo series, which take in 4-pin PWM input, spin between 800 to 2,500 RPM, pushing up to 80.95 CFM of air, with a noise output of up to 29.7 dBA, each. Characteristic to the ROG Strix LC series, the pump-block features spirally-projecting RGB LED diffusers along the sides, and an illuminated ROG logo on top. All lighting is controlled by addressable-RGB (ASUS Aura Sync RGB). The cooler supports nearly all modern CPU socket types, including AM4, LGA115x, and LGA2066. The pump-block supports the Asetek-standard AIO CLC retention module AMD Ryzen Threadripper processors include in their PIB packages.

CUK Makes a Splash This Computex

Computer Upgrade King (CUK) is a new BTO (build-to-order) gaming PC manufacturer based out of Virginia, USA. Unlike other system integrators, CUK extends component choices all the way down to the cases. At Computex, the company showed off its Stratos Mini high-end desktop (HEDT), powered by an AMD Ryzen Threadripper 2990WX processor, AMD Radeon VII graphics, 32 GB of quad-channel DDR4-3000 memory, an ASRock X399M Taichi motherboard, and a SeaSonic Prime 1300W 80 Plus Gold PSU. Also shown off was the Continuum Mini, a compact powerhouse built around a mini-ITX motherboard. Its chops include the Core i9-9900K processor seated on an MSI MPG Z390I Gaming Edge AC motherboard; GeForce RTX 2080 Ti graphics, 16 GB of dual-channel DDR4-3200 Apacer NoX memory; and a 750W power supply.

AMD's Zen 2 Threadripper Conspicuously Absent From Company's Latest Roadmaps

We've all taken a look at AMD's March 2019 product roadmap, which showed us the upcoming 2019 tech the company would be bringing to the table in its "non-stop product momentum". However, it seems that this non-stop product momentum might be coming to an unexpected twist of fate that might delay it from entering the last station - the Zen 2-based Threadripper. In the company's latest May earnings call roadmap, the company silently removed the Zen 2 Threadripper from its product roadmap - where it used to sit right after the launch of Zen 2-based Ryzen products for consumers, is now just a big crop of the space it occupied.

This might mean many things, and a mistake on someone's part while cropping the PowerPoint slide could be the only thing going on here. However, the best and most plausible speculation that can be entertained when one considers this is simple - a supply problem. With the 7 nm node being the newest, most dense fabrication process possible, and with AMD having to share TSMC's 7 nm wafer production with a number of high profile companies - such as Qualcomm, for instance - may mean that supply is simply too tight to support Zen 2-based products across so many product stacks - Ryzen and Epyc - at the same time.

Thermaltake Rolls Out Floe Riing RGB 360 TR4 Edition CPU Cooler

Thermaltake today rolled out the Floe Riing RGB 360 TR4 Edition, a variant of this closed-loop liquid CPU cooler for AMD Ryzen Threadripper processors. Although its pump-block has the same dimensions as the original Floe Riing series, the TR4 Edition features an enlarged, rectangular copper base for more coverage of the Ryzen Threadripper integrated heatspreader (IHS).

The cooler features a 360 mm x 120 mm radiator with three included Riing Plus RGB TT Premium Edition fans, which each spin between 1,000 to 2,000 RPM, pushing 26.35 to 54.42 CFM of air-flow, with a noise output ranging between 21.8 to 33 dBA. The three fans and the pump-block feature 16.7 million-color addressable RGB embellishments, which are controlled by the included addressable RGB LED controller. The cooler can handle high enough thermal loads to support 250W TDP Threadripper WX processors with high core-counts. TR4 is also the only socket type supported by this cooler. The company didn't reveal pricing.

AMD "Castle Peak," "Rome," and "Matisse" Referenced in Latest AIDA64 Changelog

FinalWire over the past week posted the latest public beta of AIDA64, which adds support for the three key processor product lines based on AMD's "Zen 2" microarchitecture. The "Matisse" multi-chip module, which received extensive coverage over the past few weeks, will be AMD's main derivative of "Zen 2," designed for the client-segment socket AM4 platform, with up to 16 CPU cores, and the initial flagship product featuring 12 cores. "Rome" is AMD's all-important enterprise-segment MCM for the SP3 platform, with up to 64 CPU cores spread across eight 8-core chiplets interfacing a centralized I/O controller die with a monolithic 8-channel memory controller. It so happens that AMD also wants to update its Ryzen Threadripper line of high-end desktop processors, with "Castle Peak."

"Castle Peak" is codename for 3rd generation Ryzen Threadripper and a client-segment derivative of the "Rome" MCM with a reconfigured I/O controller die that has a monolithic 4-channel DDR4 memory interface, and an unspecified number of CPU cores north of 24. This is for backwards compatibility with the existing AMD X399 motherboards. AMD configures core-count by physically changing the number of 8-core chiplets on the MCM, in addition to disabling cores in groups of 2 within the chiplet. The company could scale core counts looking at its competitive environment. The monolithic quad-channel memory interface could significantly improve the chip's memory performance compared to current-generation Threadrippers, particularly the Threadripper WX series chips in which half the CPU cores are memory bandwidth-starved. The AIDA64 update also improves detection of existing Ryzen/EPYC processors with the K17.3 and K17.5 integrated northbridges.

ASUS Unveils the ROG Zenith Extreme Alpha X399 Motherboard

ASUS unveiled its new flagship motherboard for the AMD platform, designed with out-of-the-box support for 2nd gen Ryzen Threadripper WX and X processors, the Republic of Gamers (ROG) Zenith Extreme Alpha. This board features an updated design aesthetic that's aligned with the company's latest ROG Extreme motherboards on Intel Z390 motherboards. The underlying PCB layout is entirely new, and different from the original Zenith Extreme, as are the heatsinks and shrouds covering various parts of the board, including a portion of its reverse side.

The I/O shroud which runs the entire length of the board is contiguous with a large RGB LED studded shroud covering the board's two M.2-2280 NVMe slots between PCIe slots. You get a U.2 port, and additional M.2 NVMe slots through the DIMM.2 riser accessory that's included with the board. ASUS has designed the CPU VRM of this board. It's still 10-phase on paper, but uses a high-end controller; and is tuned for overclocking the beastly Threadripper WX processors. Another killer feature with this board is 10 GbE wired Ethernet, driven by an Aquantia AQC-107 controller. You still get a 1 GbE driven by an i211-AT. ASUS appears to have done some cost-cutting with the WLAN card, though, which now only supports up to 1.73 Gbps 802.11ac MU-MIMO, compared to the original Zenith Extreme's 802.11ad draft controller with 4600 Mbps top-speed. The onboard audio solution is unchanged.

AMD 3rd Generation Ryzen Probable SKUs, Specs, Pricing Leaked?

One of our readers tipped us off with a very plausible looking image that drops a motherlode of information about what AMD's 2nd generation Ryzen (aka Ryzen 3000 series) processor lineup could look like. This includes a vast selection of SKUs, their CPU and iGPU core configurations, clock-speeds, and OEM channel pricing. The list speaks of a reentry for 7th generation A-series "Excavator" as Duron X4 series, followed by Duron 300GE-series based on a highly cut down "Raven Ridge," Athlon 300GE 2-core/4-thread based on an implausible "Zen+ 12 nm" APU die, followed by quad-core Ryzen 3 3000 series processors with and without iGPUs, making up the company's entry-level product lineup.

The core counts seem to jump from 4-core straight to 8-core, with no 6-core in between, for the Ryzen 5 series. This is also where AMD's new IP, the 7 nm "Zen 2" architecture, begins. There appears to be a large APU die (or a 3-chip MCM) with an 8-core CPU and 20-CU iGPU, which makes up certain Ryzen 5 SKUs. These chips are either 8-core/8-thread or 8-core/16-thread. The Ryzen 7 series is made up of 12-core/24-thread processors that are devoid of iGPU. The new Ryzen 9 series extension caps off the lineup with 16-core/32-thread SKUs. And these are just socket AM4.

ASRock Intros X399 Phantom Gaming 6 Motherboard for AMD Threadripper X

ASRock today launched the X399 Phantom Gaming 6, its latest addition to the popular Phantom Gaming series for AMD Ryzen Threadripper processors. Note that this board only supports up to 16-core Threadripper models, the 24-core and 32-core Threadripper WX series are not supported. The Phantom Gaming features premium components (power delivery is kept clean and stable with Digital PWM, 8 Power Phase & Dr. MOS)and a relatively subdued, black-gray-red design - and like most hardware these days, it's gamer-oriented and branded. 2.5 Gbps Ethernet is one of the key features as ASRock paints it, and there is a grand total of 3x Ultra M.2 connectors and a full-length 22110 (110 mm) slot with full-coverage heatsink.

GIGABYTE Intros X399 Aorus Pro Motherboard at $270

GIGABYTE began shipping its second socket AMD TR4 motherboard since 2nd generation Ryzen Threadripper launch, the X399 Aorus Pro. If you've been paying attention to GIGABYTE's new nomenclature for Aorus, the "Pro" SKU is slotted between what was "Gaming 3" and "Gaming 5," making this GIGABYTE's most affordable TR4 motherboard, positioned below the X399 Gaming 7, and a far cry from the range-topping X399 Aorus Xtreme. The board ships with out-of-the-box support for 2nd generation Ryzen Threadripper processors. GIGABYTE appears to have reused the same exact PCB as the X399 Gaming 7, but with aesthetic updates and cost-cutting. The board's design scheme (I/O shroud and heatsink designs) are somewhat aligned with its newer generation design aesthetic introduced with its Z390 Aorus family.

Cost cutting over the X399 Gaming 7 comes in the form of the I/O shroud no longer running the entire length of the PCB, only one out of three M.2 slots getting a SSD heatsink, only two out of five PCI-Express 3.0 x16 slots getting full metal reinforcement, and the lack of a WLAN module. The board draws power from a combination of 24-pin ATX, 8-pin EPS, and 4-pin ATX, and uses an 8-phase VRM to power the CPU. Expansion slot layout is unchanged from the Gaming 7, with two x16 slots running at x16, and two taking 8 lanes from them. A fifth x16 slot is gen 2.0 x4. All three M.2 PCIe slots are wired to the CPU. The onboard audio solution is carried over, with Realtek ALC1220 CODEC, WIMA capacitors, and ground-layer isolation. The sole networking interface is a 1 GbE pulled by an Intel i211-AT controller. Available now, the GIGABYTE X399 Aorus Pro is priced at $270, a whole Benjamin cheaper than what the Aorus X399 Gaming 7 launched at.

AMD Could Solve Memory Bottlenecks of its MCM CPUs by Disintegrating the Northbridge

AMD sprung back to competitiveness in the datacenter market with its EPYC enterprise processors, which are multi-chip modules of up to four 8-core dies. Each die has its own integrated northbridge, which controls 2-channel DDR4 memory, and a 32-lane PCI-Express gen 3.0 root complex. In applications that can not only utilize more cores, but also that are memory bandwidth intensive, this approach to non-localized memory presents design bottlenecks. The Ryzen Threadripper WX family highlights many of these bottlenecks, where video encoding benchmarks that are memory-intensive see performance drops as dies without direct access to I/O are starved of memory bandwidth. AMD's solution to this problem is by designing CPU dies with a disabled northbridge (the part of the die with memory controllers and PCIe root complex). This solution could be implemented in its upcoming 2nd generation EPYC processors, codenamed "Rome."

With its "Zen 2" generation, AMD could develop CPU dies in which the integrated northrbidge can be completely disabled (just like the "compute dies" on Threadripper WX processors, which don't have direct memory/PCIe access relying entirely on InfinityFabric). These dies talk to an external die called "System Controller" over a broader InfinityFabric interface. AMD's next-generation MCMs could see a centralized System Controller die that's surrounded by CPU dies, which could all be sitting on a silicon interposer, the same kind found on "Vega 10" and "Fiji" GPUs. An interposer is a silicon die that facilitates high-density microscopic wiring between dies in an MCM. These explosive speculative details and more were put out by Singapore-based @chiakokhua, aka The Retired Engineer, a retired VLSI engineer, who drew block diagrams himself.

AMD Expands 2nd Generation Ryzen Threadripper Desktop Processor Line-up, Powering Ultimate Computing Experiences, Available Today From $649

"The dramatic transformation in the HEDT and overall PC market is driven by AMD leadership and innovation, and the AMD Ryzen Threadripper family is central to this global excitement," said Saeid Moshkelani, senior vice president and general manager, Client Compute, AMD. "We are expanding this excitement while also ensuring the HEDT market remains accessible to a broader range of creators and gamers with two new Threadripper processors that start at $649."

Alpenföhn Intros Matterhorn Threadripper CPU Cooler

Alpenföhn today introduced the Matterhorn Threadripper, a variant of its popular Matterhorn series tower-type CPU air coolers, which supports AMD socket TR4 (SP3r2). The cooler comes with an enlarged copper base, which offers full coverage of the Ryzen Threadripper IHS. Six 6 mm-thick copper heat pipes convey heat from this base through the aluminium fin-stack.

The cooler ships with a re-tuned Wingboost 2 120 mm fan, which spins between 500 - 1,500 RPM, pushing up to 106 m³h of air, with noise output as low as 18.2 dBA. Both the fins and the heat pipes feature a ceramic black coating that works to increase surface area for heat dissipation. A tube of Alpenföhn Permafrost TIM comes included. Measuring 138 mm x 100 mm x 158 mm (WxDxH), the cooler weighs about 1 kg. The company did not mention the thermal load limits of the cooler, and whether it's recommended for even the 250W TDP models such as the Threadripper 2990WX. The company didn't reveal pricing.

AMD Expresses its Displeasure Over Intel's PT Benchmarks for 9th Gen Core

AMD gave its first major reaction to the Principled Technologies (PT) controversy, in which it came out strongly against the questionable methods PT employed, in its performance comparison between the Core i9-9900K and AMD Ryzen 7 2700X, in addition to certain other Ryzen Threadripper series products. In its response, AMD made its official position on controversy clear - it is not happy with PT.

AMD prepared a long list of flaws with PT's original testing, and the areas where it did not correct the mistakes in its second testing. The company also put out a list of its own "best practices" for comparative benchmarking, which prescribes "sanitizing the operating system," "sanitizing the platform" for stock vs. overclocked testing, "sanitizing the data," and to not create a vast disconnect between the test environment and the real-world.

be quiet! Announces Dark Rock Pro TR4: High-end Air Cooler for AMD Ryzen Threadripper

be quiet!, the market leader in PC power supplies in Germany for twelve consecutive years, announces Dark Rock Pro TR4, its high-end air cooler for AMD's Ryzen Threadripper processors. Dark Rock Pro TR4 is part of the Dark Rock 4 cooler family and features a large base plate, optimized for Socket TR4 CPUs. With a sleek design and smart optimizations, Dark Rock Pro TR4 targets demanding workstation users needing the best performance at extremely low noise levels.

New PT Data: i9-9900K is 66% Pricier While Being Just 12% Faster than 2700X at Gaming

Principled Technologies (PT), which Intel paid to obtain some very outrageous test results for its Core i9-9900K eight-core processor launch event test-results, revised its benchmark data by improving its testing methodology partially. Initial tests by the outfit comparing Core i9-9900K to the Ryzen 7 2700X and Ryzen Threadripper 2950X and 2990WX, sprung up false and misleading results because PT tested the AMD chip with half its cores effectively disabled, and crippled its memory controller with an extremely sub-optimal memory configuration (4-module + dual-rank clocked high, leaving the motherboard to significantly loosen up timings).

The original testing provided us with such gems as the i9-9900K "being up to 50 percent faster than 2700X at gaming." As part of its revised testing, while Principled Technologies corrected half its rookie-mistakes, by running the 2700X in the default "Creator Mode" that enables all 8 cores; it didn't correct the sub-optimal memory. Despite this, the data shows gaming performance percentage-differences between the i9-9900K and the 2700X narrow down to single-digit or around 12.39 percent on average, seldom crossing 20 percent. This is a significant departure from the earlier testing, which skewed the average on the basis of >40% differences in some games, due to half the cores being effectively disabled on the 2700X. The bottom-line of PT's new data is this: the Core i9-9900K is roughly 12 percent faster than the Ryzen 7 2700X at gaming, while being a whopping 66% pricier ($319 vs. $530 average online prices).

AMD Introduces Dynamic Local Mode for Threadripper: up to 47% Performance Gain

AMD has made a blog post describing an upcoming feature for their Threadripper processors called "Dynamic Local Mode", which should help a lot with gaming performance on AMD's latest flagship CPUs.
Threadripper uses four dies in a multi-chip package, of which only two have a direct access path to the memory modules. The other two dies have to rely on Infinity Fabric for all their memory accesses, which comes with a significant latency hit. Many compute-heavy applications can run their workloads in the CPU cache, or require only very little memory access; these are not affected. Other applications, especially games, spread their workload over multiple cores, some of which end up with higher memory latency than expected, which results in a suboptimal performance.
