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.
Any idea on release dates and availability for Zen3 yet? Other than "2020", I mean?
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.
So would you say this is the one to jump in on? Good bang for the buck longevity on one of these for a long-ish range build cruncher? I might be able to get back in the game a bit eventually. 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.
