AMD Claims World’s Fastest Per-Core Performance with New EPYC Rome 7Fx2 CPUs

In general the 3900X is really nice, and if I did it over again, would probably do that over the 3950X.. About my only complaint is 32gb ram modules aren't available in 3000+ frequencies, so 64gb is about the max prudent amount you'll get in AM4.

It depends on what you're shoving into docker, or how much you're building in golang...

As far as gaming, all the Ryzen 3000 series perform within a couple percent of any Intel CPU close to the price point... The 10900X might do another 3-5% better for gaming, but your electricty use will nearly double for that very minor increase, not worth it imo.

You can get fast and good latency 32 GB DIMMs now. G.Skill has 4x32GB 3600 18-22-22-42, timings not the best, but tighter timings always get harder at higher speed and chips. The 3200 kits are 16-18-18-38.

Edit: Corsair also offers 3200 kits I'm pretty sure, too lazy to look up their exact specs

Yeah you can but the prices though. In my area ram prices increased about 40% since December.

Other than price, why the recommendation for the 3900x over 3950x?

I don't own either, but in researching these processors, my guess is that price, or rather value would be the biggest factor.

One of the main value propositions (for a programmer) of going from a Ryzen 5 or Ryzen 7 to a Ryzen 9 is that you get double the amount of cache (and four times the amount of an Intel Core i9-9900K).

Both the 3900X and the 3950X have that extra cache. Aside from that, the extra 4 cores are going to have diminishing returns for most programmers, and the bump in boost clocks is minimal (though the ability to achieve those clocks with the same TDP as the 3900X is impressive).
