AMD Ryzen Threadripper 2970WX Review: 24 Cores on a Budget

VRMark, 3DMark, AotS: Escalation and Dawn of War III

Test Notes

Unlike AMD's previous-gen Threadripper models, the WX-series CPUs include a Game Mode preset in the Ryzen Master software that disables three of four dies. Company representatives tell us this facilitates optimal performance in games. But AMD also provides toggles that allow experimentation with two- and four-die configurations. For this review's gaming benchmarks, we tested the Threadripper processors with Game Mode enabled. Ryzen Threadripper 2970WX consequently becomes a 6C/12T CPU for those tests.

Dynamic Local Mode is a new feature that debuts with the 2970WX, and it only applies to the WX-series models. We include a second bar chart for each game to quantify performance with this feature enabled or disabled at stock settings (labeled Creator/DM).

Gaming performance is measured at 1920x1080, minimizing graphics bottlenecks. Of course, as you step up to 2560x1440 or 3840x2160, the differences between processors shrink.

We have application test results with an overclocked Ryzen Threadripper 2920X, but weren't able to run that chip in its tuned state through our game benchmarks before it stopped working. Once we're able to get it back up and running, we'll update the gaming charts.

VRMark, 3DMark

We aren't big fans of using synthetic benchmarks to measure performance, but 3DMark's DX11 and DX12 CPU tests provide useful insight into the amount of horsepower available to game engines.

Ryzen Threadripper 2970WX's Game Mode drops the 24-core chip's count down to six active cores, but also prevents bandwidth-starved execution resources from handicapping performance during the DX11 and DX12 tests. Nevertheless, the 2970WX drops to the bottom of our chart. A dual-die 2920X easily beats the 2970WX, so it's clear that the quad-die CPU's topography is the issue.

UL's VRMark test lets you gauge your system's suitability for use with the HTC Vive or Oculus Rift, even if you don't currently own an HMD. UL defines a passing score as anything above 109 FPS. Precision Boost Overdrive yields a 13.6 FPS gain for the Threadripper 2970WX.

Ashes of the Singularity: Escalation

Ashes of the Singularity: Escalation is a computationally intense title that normally scales well with thread count.

Again, Ryzen Threadripper 2920X facilitates better performance than the 2970WX at stock settings. If there's a silver lining here, it's that PBO pushes today's subject beyond a stock 2990WX.

The second slide shows us that Dynamic Local Mode, which we used in tandem with Creator mode, imposes a slightly lower frame rate. Dynamic Local Mode's background process avoids shuffling threads that fully utilize the CPU's resources. Ashes of the Singularity does this, so the result isn't entirely surprising.

It is clear, however, that the 2970WX doesn’t scale linearly as cores and threads are added in Creator mode. You'll get similar (or better) performance in Game mode with just six cores active.

Threadripper processors perform well in this title. The 2970WX lands close to the top with PBO enabled, though the much cheaper Ryzen 7 2700 isn’t far behind.

The 2970WX in Game mode is faster than the same chip in Creator mode, even after we enable AMD's new Dynamic Local Mode. The company touted that switch's ability to improve performance "up to 49%,” but remember that those gains happen in Creator mode. You probably don't want to game in Creator mode.

    Threadripper and Cake or Death!
    I'll have the Threadripper please.
    Very well! Give him Threadripper!

    This would be ideal for me, but it is pricey for now.

    Basin Falls may be soldered, but considering that the solder in the 9000-series doesn't seem to do as much as people had hoped, we should be prepared for there not to be a lot of OC headroom.

    If you can't afford it, you don't need it. Anyone who can make actual use of this CPU is using it in a business which is generating the money necessary to pay for it.

    Exactly, if I were in a business to generate content I would take the 24 core TR4 CPU over the 18 core Intel equivalent for less money any day of the week. Not everything is made to play games on it.

    Looks like the I9-9900K is the best bang for the buck.

    I would be able to make some money with that for sure. fine, now where is that business plan?
