Retesting the 2990WX

Earlier today, NVIDIA released version 399.24 of their GeForce drivers for Windows, citing Game Ready support for some newly released games including Shadow of the Tomb Raider, The Call of Duty: Black Ops 4 Blackout Beta, and Assetto Corsa Competizione early access.

While this in and of itself is a normal event, we shortly started to get some tips from readers about an interesting bug fix found in NVIDIA's release notes for this specific driver revision.

Specifically addressing performance differences between 16-core/32-thread processors and 32-core/64-thread processors, this patched issue immediately rang true of our experiences benchmarking the AMD Ryzen Threadripper 2990WX back in August, where we saw some games resulting in frames rates around 50% slower than the 16-core Threadripper 2950X. 

This particular patch note lead us to update out Ryzen Threadripper 2990WX test platform to this latest NVIDIA driver release and see if there were any noticeable changes in performance.

The full testbed configuration is listed below:

Test System Setup
CPU

AMD Ryzen Threadripper 2990WX

Motherboard ASUS ROG Zenith Extreme - BIOS 1304
Memory

16GB Corsair Vengeance DDR4-3200

Operating at DDR4-2933

Storage Corsair Neutron XTi 480 SSD
Sound Card On-board
Graphics Card NVIDIA GeForce GTX 1080 Ti 11GB
Graphics Drivers NVIDIA 398.26 and 399.24
Power Supply Corsair RM1000x
Operating System Windows 10 Pro x64 RS4 (17134.165)

Included at the end of this article are the full results from our entire suite of game benchmarks from our CPU testbed, but first, let's take a look at some of the games that provided particularly bad issues with the 2990WX previously.

The interesting data points for this testing are the 2990WX scores across both the driver revision we tested across every CPU, 398.26, as well as the results from the 1/4 core compatibility mode, and the Ryzen Threadripper 2950X. From the wording of the patch notes, we would expect gaming performance between the 16-core 2950X and the 32-core 2990WX to be very similar.

Grand Theft Auto V

GTA V was previously one of the worst offenders in our original 2990WX testing, with the frame rate almost halving compared to the 2950X.

However, with the newest GeForce driver update, we see this gap shrinking to around a 20% difference.

AMD's Ryzen Threadripper 2950X now available for purchase for $899

Today, AMD's 2nd generation Ryzen Threadripper 2950X has finally reached retail availability. As you might remember from the launch a few weeks ago, the 32-core Threadripper 2990WX has already been on store shelves, but the 2950X was set to arrive on August 31st.

For those that need a bit of a refresher on 2nd generation Threadripper, you check out our full review of both the 2950X and 2990WX. Ultimately, we found the Threadripper 2950X is a great CPU for people looking to bridge the gap between content creation and gaming, with near top-level performance in both areas.

So far, we've spotted the 2950X on Newegg and at Microcenter, and Amazon.

The 12-core and 24-core variants of 2nd generation Threadripper processors are still set to be coming later in the year.

Vive la différence! Threadripper 2 on Linux and Windows 10

Subject: Processors | August 21, 2018 - 03:51 PM |
Tagged: 2990wx, threadripper 2, linux, windows 10, amd

Windows 10 is much better at dealing with multithreaded tasks but Linux has been optimized for both high core counts and NUMA for quite a while, so looking at the performance difference is quite interesting.  Phoronix tested a variety of Linux flavours as well as Windows 10 Pro and the performance differences are striking, in some cases we see results twice as fast on Linux as Win10.  That does not hold true for all tests as there are some benchmarks which Windows excels at.  Take a look at this full review as well as those under the fold for a fuller picture.

"Complementing the extensive Linux benchmarks done earlier today of the AMD Threadripper 2990WX in our review (as well as on the Threadripper 2950X), in this article are our first Windows 10 vs. Linux benchmarks of this 32-core / 64-thread $1799 USD processor. Tests were done from Microsoft Windows 10 against Clear Linux, Ubuntu 18.04, the Arch-based Antergos 18.7-Rolling, and openSUSE Tumbleweed."

6GHz across 32 cores, ThreadRipping mayhem

Subject: General Tech | August 16, 2018 - 02:28 PM |
Tagged: amd, threadripper 2, 2990wx, overclocking, LN2

The low cost workstation class 2990WX has been verified as running at 5.955GHz on an MSI MEG X399 Creation board, with the help of a lot of liquid nitrogen.  The Inquirer has links to the setup that Indonesian overclocker Ivan Cupa needed in order to manage this feat, which required fans to cool certain portions of the motherboard as well.  You are not likely to see this set up installed in a server room but the achievement is no less impressive as that is an incredible frequency to reach.  Check it out in all it's glory.

"So far, it would seem that AMD is on top when it comes to willy-waving, though it's worth noting that overclocked performance is a tad nebulous and real-world in-app performance is really where choosing an Intel or AMD chip comes to play."

ThreadRipper 2: Die Four Real

Tagged: Zen+, Threadripper, second generation threadripper, ryzen, Intel, Core i9, 7980xe, 7960x, 7900x, 2990wx, 2950x

The 2950X and 2990WX are both ThreadRipper 2 chips but are very different beasts under the hood.  The 2950X has two active die similar to the original chips while the 2990WX has four active die, two of which utilize an Infinity Fabric link to the other two to communicate to the memory subsystem.  The W in the naming convention indicates the 2990WX is designed for workstation tasks and benchmarks support that designation.  You will have seen our results here, but there are many other sources to read through.  [H]ard|OCP offers up a different set of benchmarks in their review, with a similar result; with ThreadRipper AMD has a winner.  The 2990WX is especially important as it opens up the lucrative lower cost workstations market for AMD.

"AMD teased us a bit last week by showing off its new 2nd Generation Threadripper 2990WX and 2950X packaging and specifications. This week AMD lets us share all our Threadripper data we have been collecting. The 2990WX is likely a lot different part than many people were expecting, and it turns out that it might usher AMD into a newly created market."

Widening the Offerings

Today, we are talking about something that would have seen impossible just a few shorts years ago— a 32-core processor for consumers. While I realize that talking about the history of computer hardware can be considered superfluous in a processor review, I think it's important to understand the context here of why this is just a momentous shift for the industry.

May 2016 marked the launch of what was then the highest core count consumer processor ever seen, the Intel Core i7-6950X. At 10 cores and 20 threads, the 6950X was easily the highest performing consumer CPU in multi-threaded tasks but came at a staggering $1700 price tag. In what we will likely be able to look back on as the peak of Intel's sole dominance of the x86 CPU space, it was an impossible product to recommend to almost any consumer.

Just over a year later saw the launch of Skylake-X with the Intel Core i9-7900X. Retaining the same core count as the 6950X, the 7900X would have been relatively unremarkable on its own. However, a $700 price drop and the future of upcoming 12, 14, 16, and 18-core processors on this new X299 platform showed an aggressive new course for Intel's high-end desktop (HEDT) platform.

This aggressiveness was brought on by the success of AMD's Ryzen platform, and the then upcoming Threadripper platform. Promising up to 16 cores/32 threads, and 64 lanes of PCI Express connectivity, it was clear that Intel would for the first time have a competitor on their hands in the HEDT space that they created back with the Core i7-920.

Fast forward another year, and we have the release of the 2nd Generation Threadripper. Promising to bring the same advancements we saw with the Ryzen 7 2700X, AMD is pushing Threadripper to even more competitive states with higher performance and lower cost.

Will Threadripper finally topple Intel from their high-end desktop throne?
