Yep. It’s odd but with the number of required mitigations, especially in virtualization environments, they’re getting dropped fast now (they get really slow with all those turned on, and if you’re exposing at all to the web…). Plus power consumption levels have changed so much that they’re just not worth it. Especially with all the broadwell and later dropping.
Bingo. I’ve got a couple of 2690V3 if you want them - just the procs. They’ve been sitting in a static bag for two years now.
Avoid anything pre-Rome. Can’t remember where Milan fell into that.
Whacky performance issues at times. Early Epyc was not good - although the low core counts didn’t have most of the issues.
I have some piles of DDR4 I’ll sell you cheap. How much do you need?
Like literal PILES.
Early Threadripper and Epyc CPUs had lots of performance issues due to the internal latency across CCX complexes and CCDs. This was a problem with Epyc, as NUMA access was sometimes really bad because of the CCX and CCD design. It made up for it somewhat with raw memory bandwidth. Whereas Threadripper didn't have enough memory bandwidth for certain applications.
This was really apparent on CPUs like the 2970WX and heavy multithreaded workloads.
