What the [$4000 64c/128t] 3990X Brings to the Table
As of February 6th, 2020, [3990X Engineering Sample] gave the highest single-socket Cinebench R20 score in the world [31304]
The first and most important thing to understand about the 3990X is that this is not a CPU for everyone. The vast majority of applications are not designed to scale this high. Windows itself is not designed to scale this high. Microsoft’s support for more than 64 threads in Windows is a bit of a kludge.
by default, [Windows] applications can only use 50 percent of the 3990X’s 128 threads [some applications have work-arounds to use all 128]
3990X is for professionals. For now, most desktop users/gamers should not go higher than AMD Ryzen 9 3950X 16-Core/32Thread ($750).
EDIT: This article was in error. Latest W10 Pro does support full 64c/128t according to AMD. Older W10 Pro updates may not.
