Isn't linear algebra one of the other things GPUs are good at?
I think you're also looking at the release prices for the CPUs rather than the current ones. Using today's prices from Newegg, the Threadripper 1950X is $699, the (newer/faster) 2950X is $859, meanwhile the i9-7900X is $1275, up from its $989 release price presumably due to Intel's current manufacturing issues. And the AMD processors have 60% more cores/threads with, avx notwithstanding, generally equivalent performance per thread.
I expect you're right that there are niche workloads where avx512 is a real advantage, but it's starting from a pretty deep hole on the price/performance front in general.
