Aside from general improvements in speed and maybe power consumption, is there anything about zen3 that would significantly help crunching? Anything like AVX-512, or a huge increase in L3, or...?

No AVX 512 but it blows the doors off of a 2990WX because all dies have direct memory access.
I guess I am asking about how does Zen3 compare to Zen2? Is Zen3 going to be such more than Zen2 (my my 3970X)? Does Zen2 have the same problem that your Zen1 (2990WX) has?Quote:

Not yet. Still no new confirmed info. Pretty sure there won't be a core increase this time though
5950X to boost 4.9GHz. 105W TDP. 16c/32t. 64MB of L3 cache + 8MB of L2. 19% IPC improvement. Compatible with the same socket though support on 300 series boards will be sketchy. 400 and 500 series will be no problem.
Edit: BIOS updates to support Zen 3 for the 500 series motherboards should roll out on November 5th. 400 Series in January.
The new CPUs should also be available November 5th.
Interesting to me is the L3 cache structure. With Zen2, it was 16mb for each group of 4 cores. With Zen3, it is 32mb for each group of 8 cores. Same amount total. But now you can run a bigger size of task without having to go to RAM. So it should help running big PG tasks, and increasing the thread count from 4 to 8 without taking a speed hit.
Right. Pretty sure the majority of the IPC increase is due to the latency reduction from restructuring the cache this way.Quote:

C303a is sending me some Haswell boards, never know, if this looks good and I could build one of these up, my output might look so bad forever. :DQuote:

Does this mean Intel is abandoning AVX-512? Or just for some of the future CPUs? And why?Quote:

I don't know much more than that, but seems like some (most?) developers aren't too happy about the situation.Quote:

And then there's the excessive heat. With Alder Lake though, it's going to be a clusterf*ck because some of the cores on those CPUs will be regular cores while others will be Atom cores. AFAIK there will be no HT and i wish good luck on an OS trying to schedule tasks properly because of the decreased capabilities of Atom. Will be many bugs to work out, i'm sure.Quote:
