AMD's upcoming Zen 4-powered Threadripper PRO 7975WX CPU has been spotted in a Dell Precision workstation.
AMD's Zen 4 Powered Threadripper Pro 7975WX Offers 32 Cores & Huge Performance Increase Over Predecessors
The next-gen AMD Ryzen Threadripper 7000 CPU which is part of the "Storm Peak" family will be heading to the SP6 platform. The SiSoftware Sandra database lists the CPU as a 32-core chip with 64 threads, 128 MB of L3 cache, and 32 MB of L2 cache. The CPU is expected to feature a TDP of 350W and the base clock speed is reported around 4.0 GHz.
There are also performance figures but we will get to those in a bit after talking a bit about the SKUs. A recently leaked list showed that AMD's Ryzen Threadripper 7000 CPUs would include the 7995WX, 7985WX, & 7945WX chips. There could be more chips since the 7975WX was not listed in the leak.
Furthermore, the same leak mentioned that the 7995WX was going to be supported on the SP6 platform whereas another leak showed the chip housing 96 cores which is only possible with 12 Zen 4 CCDs and that's currently only possible with a Genoa SP5 configuration. We know that there are going to be two Storm Peak platforms, a higher-end Workstation and another one catering to the HEDT user base. The WS platform is supposed to feature the LGA 6096 "SP5" socket with up to 8-channel memory and 128 PCIe Gen 5 lanes support while the HEDT platform is supposed to get the LGA 4844 "SP6" socket with 4-channel memory and 64 PCIe Gen 5 lanes support.
So at the moment, the only SKUs that we know the configurations for are the 7995WX and 7975WX. The 7985WX might feature 64 cores, followed by the 7965WX or the 7955WX with 24 cores and the 7945WX with 16 cores. The configurations for these SKUs are just speculation at this point. With the configurations out of the way, we can now talk about the performance.
SiSoftware isn't the best metric for performance evaluation but to keep things plain and simple, we used their aggregated results for the Ryzen Threadripper 3970X (32-Core) Zen 2 chip since the new 5975WX isn't listed there yet.
SiSoftware Sandra Benchmark (Highest is Better)
As you can see in the benchmarks above, the AMD Ryzen Threadripper PRO 7975WX CPU can be as much as two times faster than its Zen 2 predecessor and as little as 40% faster which is still a very impressive jump. The real comparisons should be against the Zen 3 based part such as the 5975WX but seeing these scores, the new Zen 4 chips should offer at least a 20-40% boost in multi-threaded heavy applications which is simply outstanding for workstation builders.
The launch of the next-gen AMD Ryzen Threadripper 7000 "Storm Peak" CPUs is expected in late 2023 if everything goes smoothly. Expect more information in the coming months.
