You definitely have to spend significantly more than $170 to get any recent amd or intel cpu that can do faster 8+ multicore than dual 2696/7 v2. and even if we are talking about single cpu, you would have to spend significantly more than $80 to get any recent amd/intel cpu that can beat one 2696/7 v2 in 8+ multicore, although in this case the benefit is not as good as in the case of dual 2696/7 v2

It's really about 1-4 core performance is what make the newer cpu much better than the 2696/7 v2

That's why I purchased a 9600KF as opposed to a 9900KF. It's basically identical in performance up to 6 cores, and what most people don't really get is that you will rarely use more than 6 cores, and even if you do, it's still not going to be much slower. It's not like a 6 core CPU cant handle processing data that is more oriented for an 8 core CPU. People think that if a game uses 8 cores, it will totally suck on anything less than an 8 core CPU. This is not the case.

it seems unlikely that for double precision calculations any two v2 chips will come to anything near current ones having 2 avx512 units per core. As for bandwidth, the 10980XE has 4-channel max bandwidth 94 GB/s which is not that far from that of a pair 2697v2 while ignoring that for actual applications data may have to be pulled across qpi. even with superior combined bandwidth, v2s do not seem to have the double precision speed to compete with current ones.

for a chip to be worth considering it must have a min level of performance. cost becomes an issue once this threshold has been crossed. the way competition between intel and amd is going, v2s will probably become ignorable in the next year or two.

Have to make sure your software use avx512 though
