32-Core/64-Core Zen3 for Workstation, AMD Ryzen Threadripper Pro 5975WX/5995WX : Bodnara Article

While AMD is gearing up for the launch of its Ryzen 7000 series desktop processors based on the Zen 4 architecture, there are other products for the workstation market that want more performance than desktop CPUs with up to 16 cores.

The AMD Ryzen Threadripper series is the protagonist, working in areas where multi-threaded workloads are the mainstay, with more CPU cores and threads, more memory channels, and powerful system scalability using workstation-class motherboards. efficiency can be increased.

The AMD Ryzen Threadripper Pro 5000 WX series, which we will be reviewing today, is a product that can create high-performance workstations by configuring up to 64 cores and 128 threads based on the Zen 3 core architecture, which has been well received in the desktop PC market.


Up to 64-core workstation processor based on Zen 3

AMD Ryzen Threadripper Pro 5000 WX series is a CPU made for the workstation market based on the Zen 3 core architecture that goes into the existing Ryzen 5000 series desktop processors.

The Zen 3 architecture is designed based on the integrated 8-core CCX (Core Complex) structure, and the Ryzen 5000 series desktop processors include up to two 8-core CCXs, and the 16-core CPU is the top model. Ryzen Threadripper Pro 5000 WX series can make a CPU that supports up to 64 cores and 128 threads with up to 8 of these 8-core CCXs.

In addition, Ryzen desktop and mobile processors are limited to 2-channel DDR4 memory, but the Ryzen Threadripper Pro 5000 WX series can configure 8-channel memory, which is higher than the 4-channel Ryzen Threadripper. It supports 128 PCIe 4.0 lanes and has an improved maximum boost clock compared to the previous generation, full-memory encryption, and AMD Shadow Stack security features.

Instead, the AMD WRX80 chipset-based platform with the sWRX8 CPU socket is used instead of the TRX40 platform used in the existing Ryzen Threadripper. Ryzen Threadripper CPUs and motherboards are not compatible with each other, so both the CPU and motherboard must be reconfigured rather than upgraded.

ASUS Pro WS WRX80E-SAGE SE WIFI, one of the motherboards that support Ryzen Threadripper Pro WX series, is a workstation model with an Extended ATX (EEB) form factor. Supports Intel dual 10G Ethernet, Intel Wi-Fi 6 AX200 module, dual USB 3.2 Gen2 Type-C ports, 3 M.2 PCIe 4.0 slots and 2 U.2 slots, up to 2TB of 8-channel memory and ECC memory .

Here, it features a server-grade remote management solution and various heat sinks, enhanced user convenience, comprehensive compatibility verification, and excellent durability and stability.

Although the supported platform has changed, the CPU mounting method is the same as the existing Ryzen Threadripper. Loosen the three star screws, raise the double socket cover, and then slide the Ryzen Threadripper Pro WX series processor into the guide and install it.

AMD Ryzen desktop processors support 2-channel and Ryzen Threadripper 4-channel memory, but Ryzen Threadripper Pro 5000 WX series can configure 8-channel memory, so it is recommended to use all memory slots on the motherboard. It officially supports up to DDR4-3200MHz memory, and the memory can be expanded up to 2048GB (2TB) with a 256GB module per slot.

However, even if it supports DDR4-3200MHz, if you plug in any 8 memory modules, the system stability may be lowered because the timing and setting values ​​for each memory are different. Even for products that support the memory overclock profile (XMP), XMP can be used in the BIOS as well, but there is a high possibility that other modules that do not support it may not work properly.

In the board country, there are no 8 identical modules of DDR4 memory for testing, so 8 channels were configured in this way and the memory clock was lowered to DDR4-2133MHz, but users who configure the actual Ryzen Threadripper Pro system will not install the memory in this way. .

In addition, the Ryzen Threadripper Pro does not have a basic CPU cooler, so a cooling solution must be purchased separately. The basic TDP is 280W, the same as the Ryzen Threadripper 3000 series, and as the number of cores increases, the base clock is lowered to control heat. see.

However, since the Ryzen Threadripper series CPU has a considerably larger area than the general desktop CPU, there are not many types of Threadripper-optimized coolers that can cover the entire CPU area, and it is difficult to obtain.

32- and 64-core Ryzen Threadripper Pro CPU performance?

AMD Ryzen Threadripper Pro 5000 WX series consists of 5 types starting with 12 cores and up to 64 cores. Lower models such as 12 or 16 cores do not differ in the number of cores from desktop processors, so unless you want to take advantage of 8-channel memory and workstation platform, the higher model with more than 24 cores is often selected.

The products tested by Bodnara are also the 5995WX with 64 cores and 128 threads and 5975WX with 32 cores and 64 threads, which are the top models of the Ryzen Threadripper Pro 5000 WX series.

The operating system was Windows 11 Pro 64-bit (Windows 10 Pro 64-bit) version. For general CPUs, the CPU usage rate is also displayed in the logical processor of the task manager, but the 32-core, 64-thread Ryzen Threadripper Pro 5975WX and the 64-core, 128-thread 5995WX have so many threads that they barely show the numbers.

If you run Cinebench R23, Blender, and 7-Zip benchmarks, you can see that Ryzen Threadripper Pro’s multi-core score and rendering and compression/decompression performance are higher than those of general desktop processors.

The performance difference was not as big as I thought compared to the doubled CPU cores and threads, including the lower base clock of the 5995WX with 64 cores and 128 threads, and the WRX80 test system was 8-channel memory, but the clock was DDR4 due to mixed memory modules. It seems that the low setting of -2133MHz also worked.

If you look at the V-Ray benchmark, you can see that the increased CPU cores and threads affects not just CPU rendering operations, but also GPU CUDA operations. In the GeForce RTX 3070 independent test without CPU, there was no difference in GPU rendering performance of the two systems, but rather the 5975WX side result was slightly higher. The results of the Ripper Pro 5995WX system were highly measured.

On the other hand, there was no performance difference between the two CPUs or the Ryzen Threadripper 5975WX, which had a higher base clock, scored higher in tasks where the CPU clock was more advantageous than the number of CPU multi-cores/threads.

This kind of test or use environment can be satisfied even with the Ryzen desktop processor without going to the Ryzen Threadripper Pro series, so it is only a reference.

Ryzen Threadripper Pro 5000 WX Series for Workstations

The AMD Ryzen Threadripper Pro 5000 WX series is not intended for the general desktop PC market or high-end gaming PC, but for CPU-intensive workstation environments that require more CPU cores and threads.

Workstation is an area that needs to be approached in a different way than a typical desktop PC, from CPU price to supported motherboards, number of memory, case, power, and cooling solution. This is because, if there is a difference in the manpower, time, and results that are put into work, even if the initial investment cost is high, work efficiency can be improved and it can be more profitable in the long run.

Of course, there is a big price difference between the Ryzen Threadripper Pro 5995WX and 5975WX, which is not simply a difference in product grade, but because the 5975WX, which doubles CPU cores, threads, and cache memory, has two configurations into one. . In the desktop processor market, it is about the difference between the 16-core Ryzen 5950X and the 8-core Ryzen 5700X.
