Probably because it's (much) better binned than the 74F3Since the the 16-core Epyc 73F3 has a higher list and street price than the otherwise similar 24-core Epyc 74F3, I would reserve the former for some ultra-niche applications.
What do you mean? We have 1536 machines with Xeon Gold 6248 (61,440 cores) and 576x2 machines with Xeon Gold 6138 (23,040x2 cores). When I run models, I can ask Nastran to use upto 256 machines (40 cores each) and the solver uses DMP and SMP to split the work load. There's a lot of overhead to split the model over multiple machines (nodes) so it's never worth it so far.How did you test 400 cores?
Your statement of anything above 8 cores not paying back dividends smells like RAM is the bottleneck here. If that is the case, you have to look into acceleration with GPUs if software supports it (like 4x 3090 in the system), or, implement a compute cluster with more than one machine.
Where do you see the street price from? I just searched newegg and amazon and came up empty.Since the the 16-core Epyc 73F3 has a higher list and street price than the otherwise similar 24-core Epyc 74F3, I would reserve the former for some ultra-niche applications.
The current TR pro is the 39xx series. Are you saying that I should skip 2 generations (wait for the 5xxx chip)?2 EPYC EPYC 73F3 (16C) + all channels populated with Dual-Ranked DDR4-3200 DIMMs should give you a nice performance boost!
I wouldn't go with the 72F3 (8C), that might actually be not enough cores.
Higher clock, more modern µArch, 33% more memory channels (8 instead of 6), much higher memory clock (3200 instead of 2666), two CPUs instead of one
If you want to stay with single socket, you might try Threadripper Pro (but wait for the 5000 line to be released), because with TR Pro you can overclock memory. If you're willing to work without ECC and do some work on the overclocking, you might be able to get 8 Channels @ 3600Mhz with much lower timings than ECC DIMMs (CL14 or CL16 instead of CL22)

AMD is skipping a thousand in their naming scheme. TR 5000 (Zen3 architecture) will be the direct successor to TR 3000 (Zen2).The current TR pro is the 39xx series. Are you saying that I should skip 2 generations (wait for the 5xxx chip)?
