Now that the NDA is over, we can finally reveal EVERYTHING we know about the new AMD Ryzen Threadripper PRO HEDT processor family!
AMD Ryzen Threadripper PRO : What Is It?
The AMD Ryzen Threadripper PRO is a new HEDT processor family, mirroring what Ryzen PRO is to Ryzen.
Unlike the Ryzen Threadripper, the Threadripper PRO is targeted at professional studios, designers, engineers and data scientists.
The AMD Ryzen Threadripper PRO series will offer these features over “regular” Threadripper processors.
- new sWRX8 socket and WRX80 chipset
- 8 DDR4-3200 memory channels, instead of just 4
- 2X memory bandwidth over 3rd Gen Threadripper
- Support for UDIMM, RDIMM, LDRIMM, 3DS RDIMM with ECC support, instead of just UDIMM with ECC
- Up to 2 TB of memory, instead of just 256 GB
- 128 PCIe 4.0 lanes, instead of just 64
- AMD PRO Technologies, including Secure Processor and Memory Guard
- 18 months of planned software stability
- 24 months of planned availability
AMD has already chalked up one design win with the Lenovo ThinkStation P620 – the world’s first and only 64-core workstation!

AMD Ryzen Threadripper PRO : Performance
Threadripper PRO 3945WX
According to AMD, the “baby” of the family will offer 12% better single-threaded performance in CINEBENCH R20, and 28% better multi-threaded performance than a competing 12-core Intel Xeon processor.
They say that this is targeted at those whose software is licensed on a per-core basis. Its high performance per core will allow for better performance, without resorting to more cores and corresponding licence fees.
Threadripper PRO 3955WX
AMD also showed how the 16-core 3955WX can render 14% faster than an 18-core Intel Xeon processor.
Threadripper PRO 3995WX
AMD compared the flagship Threadripper PRO 3995WX with its 64 cores against two Intel Xeon Platinum 8280 processors, with 56 cores.
In the SPECviewperf13 benchmark, that 8-core, 16-thread advantage gave the 3995WX a performance advantage between 4% and 37%.
