For those who might be interested for a cheaper alternative - Intel Xeon 8280 QS is $1,800 USD each, a pair of those (56 cores) on a supermicro mb with 12 x 16G RAM is about $5k USD. It has an impressive Cinebench R15 score of 7,800+

Where do you get the $1,800 price? Intel says the recommended price is around $10,000:

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?

Huh? That Xeon in the base-spec MP is a $750 part: https://ark.intel.com/content/www/us/en/ark/products/193739/...

(As someone who buys Apple since 25+ years) Apple pricing has never been cost driven, but value and brand driven.

Games!? No Man's Sky had trouble with SSE 4.1 being a requirement, and ended up patching it out... let alone AVX, AVX2, or AVX512. Typically, games won't take advantage of new instruction sets until it's ready to be a minimum requirement, as otherwise you need to maintain two code paths, the benefit of which is only to be speeding up execution on what are already the more powerful CPUs. What games can benefit from AV…

Not now obviously as it is not mainstream yet, but AVX512 makes developer's life way easier than older AVX sets. So I see no reason why game engine developers wouldn't use them in the future. For now only some server-specific workloads use AVX512.

It's going to be a long, long time - at least a decade. I'd go as far as to say "never" is plausible, depending on how ARM penetration plays out.

If the consoles go ARM before AVX-512 has been standard on new PCs for years, it may just not be worth it.

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... ).

Now that’s some great news. I want an AMD Apple system now.

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.

That is the brilliance of Chiplet strategy. Those 74nm 7nm Die are extremely cost effective. ( For reference they are even smaller than the SoC used in iPhone ) The 14nm I/O die ( 400mm2 ) seems to be most expensive part. I wonder what cost improvement could be done in that area.

And Note: That 5K CPU has 256MB of L3 Cache. May be I could Run the OS not in RAM, but in Cache.

Except it dosent because there are 4+ mutually incompatible versions of AVX instruction sets.

Gotta love the price segmentation.

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 ?

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

It wouldn't matter. You can't look at cost / transistor without factoring in Die Size and yield. Not to mention the cost of Higher Performance and Low Power Transistor are different. And the wafer price ( Cost / Transistor ) also exclude all the design cost and tooling around the node.

And AVX512L should further improve that.

What value?
