CES 2021 | AMD Ryzen Threadripper PRO 3955WX, 3975WX, and 3995WX to go on store shelves soon; EPYC Milan processors vanquish Xeon Gold chips in forecasting comparison
The Ryzen Threadripper PRO 3955WX, 3975WX, and 3995WX were launched back in July 2020 (along with the 3945WX) as OEM-only parts, with devices such as the Lenovo ThinkStation P620 taking advantage of the immense SMT capabilities of these AMD workstation processors. However, it appears Team Red has now decided to let desktop PC builders get hold of one of these chips for their own DIY projects, with the Threadripper PRO SKUs expected to arrive on store shelves in March 2021.
The available series starts with the 16-core, 32-thread Ryzen Threadripper PRO 3955WX that has a total cache of 72 MB and can process at 3.9 GHz to 4.3 GHz. Next up is the Ryzen Threadripper PRO 3975WX with 32 cores and 64 threads, 144 MB cache, and clock rates from 3.5 GHz to 4.2 GHz. At the top of this particular product stack is the Ryzen Threadripper PRO 3995WX that will drive a workstation with 64 cores, 128 threads, 288 MB cache, and 2.7 GHz to 4.2 GHz clock rates. All three parts have a TDP of 280 W and offer 8-channel memory support for up to 2 TB ECC UDIMM, RDIMM, and LRDIMM.
On top of this news, AMD also teased the 3rd Gen EPYC server processors, which sport the codename “Milan”. Two 32-core pre-production EPYC 7003 chips managed to demolish an Intel server powered by two 28-core Xeon Gold 6258R processors in a weather forecast-related benchmark. Apparently, the AMD Milan parts outperformed the Intel chips by around 68%. More details about the upcoming Zen 3-based server processors, which should also include a 64-core SKU (and maybe even more), will be revealed later in the first quarter of this year.
