AMD Ryzen Threadripper 3990X Windows Performance
First, we are going to move through our Windows suite before we proceed to our Linux testing. Instead of focusing on lower-end mainstream products, we are going to focus on higher-end parts.
AMD Ryzen Threadripper 3990X AIDA64 Memory Test
AIDA64 memory bandwidth benchmarks (Memory Read, Memory Write, and Memory Copy) measure the maximum achievable memory data transfer bandwidth.
This is actually a bigger deal here than when we saw it on the lower-core count parts. With 64-cores, having only 4-channel memory bandwidth means that the bandwidth per core goes down considerably. More cores may sound great, but effectively these 64-core high-frequency parts have similar memory bandwidth as the AMD EPYC 7002 4-channel optimized parts (8-16 core) at DDR4-3200. We discussed this in an article here, and a video:
For many applications, that is not exactly a balanced look. Intel is offering more bandwidth for fewer cores with the Xeon W-3200 line. In that article/ video, we discuss that there are applications such as in-memory databases and HPC applications such as ANSYS Fluent that are extremely sensitive to memory bandwidth. For those, the Ryzen Threadripper 3990X is probably not the optimal choice. There are other applications that are fine with this, and a great example is rendering.
AMD Ryzen Threadripper 3990X Cinebench R15
Here are our Cinebench R15 results:
With 64 cores, we get a good result.
AMD Ryzen Threadripper 3990X Cinebench R20
We have started running Cinebench R20 in our workstation reviews as it is a much larger test. We have run these in up to 128 core/ 256 thread systems as you can see in Crushing Cinebench V5 AMD EPYC 7742 World Record Edition.
AMD Ryzen Threadripper 3990X Geekbench 4
Geekbench is a popular Windows benchmark. Soon we will start using Geekbench 5 as well.
Geekbench, especially in Windows, starts to struggle at higher core counts. We saw this in our 128 core Geekbench 4 2P AMD EPYC 7742 Sets World Record piece several months ago. Here, we also see the impact of having to lower the per-core clock speeds to fit 64 cores onboard.
AMD Ryzen Threadripper 3990X 3DMark PCI Express Bandwidth
3DMark feature tests are special tests designed to highlight specific techniques, functions or capabilities. The 3DMark PCI Express feature test is designed to measure the bandwidth available to your GPU over your computer’s PCI Express interface.
The test aims to make bandwidth the limiting factor for performance. It does this by uploading a large amount of vertex and texture data to the GPU for each frame. The result of the test is the average bandwidth achieved during the test.
Next, we are going to look at our SPECworkstation results before finishing with our Windows performance results and then transitioning to Linux benchmarks.
