Xilinx UltraScale Questions

Can these be used for chess engines? How much are they? Will they hook up with a HEDT? Thanks.

Sure they can. It doesn't matter how much FPGA's are. It would cost significantly more to make a functional chess engine on one. Coz:
1) Very few ppl (less than a handful) can actually do it
2) It would take a large effort to do it

In other words it's not enthusiasts kind of effort. It's an effort for the well paid experts.

Thanks. I will no longer consider it relevant for chess.

It would be interesting to know how powerful a TPU one could make from these things, for simulating neural nets.

Not enough. I did an analysis at one point after the first gen TPU appeared and you could get maybe half TOPS of the first get TPU (like around 50) with the largest Virtex Ultrascale+ chip at that time (I think it was 9P with 2.5 million LUTs and like 7k DSPs).
If you want anything competitive these days in CMOS you need at least 10nm ASIC.
There are however, other ways beyond CMOS ;).
