If you need AVX/AVX2/AVX512 then go intel. Otherwise this AMD chip would be my choice for most applications.

Didn‘t intel start segmenting their processor on avx support? So only the expensive processors get avx512?

Note that the 1P variant costs only $4,955, or under $80 per core. The consumer chips cost roughly $50/core, making this the flattest ramp I can personally remember.

Does anyone have a graph of recent $/transistor progress?

Its obvious that moore's law is stagnant, and clock speed is dead, etc, etc.

But are we at least getting the same core size at a lower cost ?

What software is typically able to take advantage of these instructions?

My use case is solving large LP/MIP problems for power markets, do those algorithms benefit?

Back in the early 2000s Apple was getting crushed because Moto/IBM's PowerPC couldn't keep up with the 880lb gorilla Intel. Who could have predicted even a few years ago Apple would wind up in a similar situation, yet this time for having bet on Intel? Could the 8 core Mac Pro have been $3650 with a $650 Rome CPU, vs. the reality of $6k with a $3k Xeon?

I doubt Apple pays anything close to list price for CPUs.

Earlier quoted context omitted.

does avx512 bring that much of a perf advantage ?

For software that takes advantage of it it does.

Any commonly used software that benefits from AVX-512?

Not serve-y but RPCS3 benefits a lot from those.

No, bad idea. Test or check reviews for your common workloads first, then choose. New Zen cores quite powerful and there are many gotchas with AVX execution. In most cases I can see AMD would be better overall or offer good value.

I suspect apple will release comps with amd cpus, but hackintosh with amd is already good to go

They are stuck with intel because of thunderbolt.
