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.

Yes. They've been edging towards 3-D chips since the early 80's, perhaps earlier. But I'm not sure (yet) that this "stacking" is primarily aimed at increasing 3-Dness. It seems like it may be aimed more at increasing the percentage of good chips.
