7nm AMD EPYC "Rome" CPU w/ 64C/128T to Cost $8K (56 Core Intel Xeon: $25K-50K)
Yesterday, we shared the core and thread counts of AMD's Zen 2 based Epyc lineup, with the lowest-end chip going as low as 8 cores while the top-end 7742 boasting 64 and double the threads. Today, the prices of these server parts have also surfaced, and it seems like they are going to be quite a bit cheaper than the competing Intel Xeon Platinum processors.
The top-end Epyc 7742 with a TDP of 225W (128 threads @ 3.4GHz) is said to sell for a bit less than $8K, while the lower clocked 7702 and 7702P (single-socket) are going to cost $7,215 and $4,955 (just) respectively. That's quite impressive, you're getting 64 Zen 2 cores for just $5,000, while on the other hand Intel's 28-core Xeon Platinum 8280 costs a whopping $18K and is half as powerful.

And thus began the Core Wars. An era marked by nanometer skirmishes and many interwoven threads.

Long begun the core wars have.
Yet, it's as if millions of cores suddenly screamed alive and were instantly idled.
The Core count is quicker, easier, more seductive ... easily they start, quick to join you in a load. If once you start down the dark path forever will it dominate your destiny.

So funny! We used to play this on an old minicomputer in college (late 80's).

Now you mention threads, yesterday i learned about mimalloc [github.com], which has really good performance with threads. With this multicore processors it will have very even better performance than nowadays.
