AMD Ryzen Threadripper PRO 3975W 32-core CPU discovered, specifications and benchmarks leak along with four other models



More concrete evidence for the CPUs of AMD’s Ryzen Threadripper PRO series has been leaked in the form of benchmarks for the 32-core part, the Ryzen Threadripper PRO 3975WX. The benchmark discovered by TUM_APISAK shows various entries of the processor in the Geekbench 5 database in addition to its specifications and performance numbers.

We heard about the AMD Ryzen Threadripper PRO series a few days ago when we saw the first pictures of the flagship part, the Ryzen Threadripper PRO 3995WX. Now a brand new chip has leaked and this time it is the Ryzen Threadripper PRO 3975WX. The Threadripper Pro series is more suitable for workstation users, while the standard Threadripper series can be seen as an enthusiastic and prosumer-oriented family. The Ryzen Threadripper PRO family is mainly offered by OEMs and system integrators.

According to the AMD Ryzen Threadripper 3975WX specifications, the CPU has 32 cores and 64 threads. As already mentioned, the PRO series would keep the core number of standard parts. In this case, the CPU has the same core configuration as the Ryzen Threadripper 3970X. The clock rates are 3.5 GHz for the base and 4.2-4.25 GHz boost frequencies. The CPU has 128 MB L3 cache and 16 MB L2 cache. The CPU is codenamed Castle Peak and is the internal code name for the 3rd generation Threadripper family.

The platform on which the chip was presented contained an SP3 socket motherboard and 128 GB DDR4 memory. The system is part of the Lenovo wS2020 family, which could be the new line of workstations that Lenovo would introduce. In fact, Lenovo released an important announcement on July 14, which is also rumored to launch the Threadripper PRO family. Surprisingly, only 4 channels (2DPC) are mentioned in the list. It is likely that we will see both quad and octa-channel workstations from OEMs with different prices, but this has yet to be confirmed.

This could definitely be one of the various workstations that Lenovo plans to add to its launch portfolio on July 14th. With this in mind, let’s look at the performance figure of the Ryzen Threadripper 3975WX from AMD compared to the Ryzen Threadripper 3970X.

With pure performance, the AMD Ryzen Threadripper 3975WX achieves a maximum of 1270 points in single-core tests and 25519 points in multi-core tests. For comparison: The Ryzen Threadripper 3970X achieved around 1350 points in single-core tests and around 27000-2800 points in multi-core tests. This is solely due to the lower clock speeds of the parts of the Pro series. The AMD Ryzen Threadripper 3970X runs at much higher speeds of 3.7 GHz base and 4.5 GHz boost clocks.

In addition to these benchmarks, the CPU was also discovered in the user benchmark database. The CPU ran at an average clock speed of around 3.95 GHz and the same basic frequency of 3.50 GHz was reported. The CPU works a bit slower than the Ryzen Threadripper 3970X, but this is also due to the reduced clock rate of the PRO variant compared to the enthusiastic HEDT variant. Since HEDT parts are operated with TDPs of 280 W, I believe that the PRO variants could have more conservative TDPs between 180 and 250 W.

As it looks, Momomo_US has now reported that AMD will offer at least four Ryzen Threadripper PRO workstation SKUs. These include the parts AMD Ryzen Threadripper PRO 3995WX 64 Core, Ryzen Threadripper PRO 3975WX 32 Core, Ryzen Threadripper PRO 3955WX 16 Core and Ryzen Threadripper PRO 3945WX 12 Core. These parts were also mentioned by Moore’s Law is Dead in his latest video from the previous day, which you can see here.

AMD Ryzen Threadripper PRO series lineup:

CPU name CPU cores CPU thread Basic clock Boost clock L3 cache TDP price Retail launch
AMD Ryzen Threadripper 3995WX 64 core 128 threads TBD TBD 256 MB TBD TBD July 14, 2020?
AMD Ryzen Threadripper 3975WX 32 core 64 thread 3.5 4.2 GHz? 128 MB TBD TBD July 14, 2020?
AMD Ryzen Threadripper 3955WX 16 core 32 threads TBD TBD 64 MB TBD TBD July 14, 2020?
AMD Ryzen Threadripper 3945WX 12 core 24 threads TBD TBD 64 MB TBD TBD July 14, 2020?

They are supported by AMD’s new WRX80 platform, on which several board partners are currently working. Key features include 8-channel DDR4-3200 support in UDIMM, RDIMM, LRDIMM variants, 96-128 Gen4 PCIe lanes with 32 SATA switchable lanes, and some PRO features that make these chips the ultimate Workstation solution on the market.

Of course, we don’t know much about the lineup at the moment, but with the announcement of the Ryzen 4000 PRO series this month, we were definitely able to hear some details about the Ryzen Threadripper PRO series.
