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.

actually Asrock release X570 for ryzen2 with PCIE4 and thunderbolt 3 (https://www.anandtech.com/show/14455/asrock-x570-aqua-heavie...).

I do have an AMD Hackintosh, I don't see any reason you wouldn't be able to use these as a dev Hackintosh machine. It's gorgeously fast with my Ryzen 2700x, eats compilation time like no one's business and it's stable. And it's something around 1/4th the price of the same horsepower from native Intel Macs. I can't imagine the cost delta of a EPYC Rome Hackintosh to its Intel counterpart. It's not like I cheaped out e…

Impeccable internal structure and rad RGB case lighting as well as a window.

How about those adobe applications? I heard that PS, Pr, or Ai need special patch to run on amd machines

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?

In fairness, they are in a much better situation. They could swap to AMD with no real arch changes but I imagine they also would prefer their own CPUs. The fact of the matter is that these CPUs are built on the same exact process as the A12 by the same fab. I would expect, at the scale they are working, a next Apple ARM cpu could be scaled to Rome core counts and have “close” performance at hilariously lower prices.

Thunderbolt is an open protocol now. They are not stuck.

does avx512 bring that much of a perf advantage ?

For software that takes advantage of it it does.

I appreciate your tautological answer. I was more looking at concrete examples with % differences in benches :)

Do you have drivers for everything? Do you think it would work on a Threadripper with many NVidia GPUs as well?

Many nvidia card don't have driver for mojave or catalina. No 9xx nvidia gpu or later on can work

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

Well, it includes some masking instructions that allow algorithms to use vectorization in cases where it's not natively processing vectors. The benefit should be similar to the thread-local control flow stack introduced in the Volta microarchitecture of Nvidia.
