AMD Ryzen Threadripper 2970WX and 2920X
Our test setup is as follows:
Lets start off with Cinebench. This free 3D-rendering benchmark supports up to 256 threads and really shows the strength of Threadripper. The multi-threaded scores are amazing! Intel retains the single threaded advantage, but for a rendering task you will always use as many cores as are available.
Next up is Blender. This free 3D creation suite is tailor made for high core-count processors and the results speak for themselves. Here, the Threadripper 2970WX easily pulls ahead of the 7980XE. The Threadripper 2920X puts in a strong showing too.
Consumer level video encoders generally arenít supportive of very high core counts at this time. Cinegyís Cinescore UHD benchmark tops out at 16 cores, and moving beyond that results in less CPU utilization.
7Zip is a file compression application that scales well with memory bandwidth as well as high core counts. AMD is strong here, putting up a good fight against the more expensive 7980XE.
For our game testing, we set the 2970WX to Game Mode via the Ryzen Master software. We disabled 3/4 of the 24 cores, resulting in an effective 6c/12t CPU. Games tend to handle lower core counts much better than higher counts and sometimes quite dramatically. Bear in mind that the vast majority of gamers use dual or quad core CPUs. A 16-core CPU, let alone a 24-core, represents a fraction of a fraction of a fraction of the market, so it will likely be some time before game developers really put resources into scaling with very high core counts.
3DMarkís physics test does actually react well to higher core counts but truth be told it doesnít really impact gameplay these days with modern CPUs capable of handling well coded physics implementations. Have you ever tried to play Ultimate Epic Battle Simulator though? 30,000 vs 30,000 units might be an interesting test for these CPUs!
Ghost Recon is one that didnít seem to struggle with high core counts. Here the AMD processors are all within a few percent of each other, while the Intel processors move ahead due to their superior single thread performance.
Far Cry 5 is one game that does seem to suffer with higher core counts. This is borne out with the 2970WX set to game mode. It easily pulls ahead of the 12 and 16 core Threadrippers and brings it into line with the 2700X. The 7980XE also loses performance vs the 8700K. Itís a good example of why you should use Game Mode, or a CPU with less cores and higher speeds, to improve gaming performance.
Rise of the Tomb Raider is another one that just doesnít like high core counts. The 2970WX with Game Mode enabled is a great example of this. Even the 2920X with 12 core trails well behind the 8 core Ryzen 2700X, while the 8700K is way out in front.
While ultimate gaming performance still favours Intel, particularly if youíre into competitive gaming at high refresh rates, remember, the gap is pretty slim at high resolution and detail settings. Still, you really should disable some of those cores if you switch from rendering to gaming. Itís great that AMD offers a one click feature to extract maximum performance in games, while leaving all those cores to be used only when they are needed.
