AMD Ryzen Threadripper PRO 5995WX with 64 cores, 5945WX with 12 cores have already been spotted on distributed computing project website.
Taken from Videocardz … Two Threadripper PRO products displayed AMD “Family 25” (Zen3) CPUs have shown up on MilkyWay@Home, a volunteer distributed computing platform. According to the pages, which were discovered by @Benchleaks, there were two separate nodes (computers) connected to the network, featuring Ryzen Threadripper 5995WX CPU as well as PRO 5945WX.
According to those pages, the Threadripper PRO 5995WX would offer 64 cores and 128 threads, whereas the 5945WX would feature 12 cores and 24 threads. Such specs align with previous rumors, which either means that they were correct or somebody is trying to spoof the network with fake results. But then why would this be hidden on a MilkyWay project, where probably no one would ever find it if not for BenchLeaks.
