It's really fascinating to watch them capture market share as you see where Intel is still entrenched for all kinds of reasons which are not price/perf wise. For example, we can't use AWS t3a instances with EPYC Cores as our Management Provider has all their images only compiled for, optimized and tested on Intel based VMs. The difference is still not large enough to bother to look into it, but next generation I expect the difference will be so large they can't ignore it.

Another couple of differences: No support for rr because of some lack of performance counters[1]. I also found that lm-sensors can barely see my AMD Ryzen at all, missing all core temp information. I'm hoping that both of these will be fixed since it doesn't seem that AMD is missing anything intrinsicly. [1] https://github.com/mozilla/rr/issues/2034 https://github.com/mozilla/rr/issues/2034

  > I also found that lm-sensors can barely see my AMD Ryzen at all, missing all core temp information. This is fixed in Kernel 5.4, and some distros backported the fix to 5.3. I'm using Debian stable, with a kernel from buster-backports, and I can see the temperature for my CPU (Ryzen 7) and the GPU (Radeon RX 580).

  And no support for Processor Trace or Coresight or some equivalent, which are amazing debug techs. Once you have them it's hard to live without...

Intel owns their own manufacturing process so they can crank out more volume than TSMC can on the smaller process nodes. TSMC Has a roadmap to 3nm by 2023, Intel is looking at 7nm by 2021. Unless Intel manufactures on TSMC's line, AMD will have a clear, near double to triple performance advantage for the next 2 generations. You're going to see Intel become the value brand for awhile and they're trying to avoid that because they are used to a cash cow.

  > near double to triple performance advantage Not even remotely close. Really, where do you get some notion of AMD having "double" the performance of Intel? Pass the dutch, bro.

  Please keep in mind that the process names have become meaningless marketing terms. Intel is currently a bit behind due to their 10nm fiasco, but it is entirely possible that Intel's 7nm will beat TSMC 3nm process. AMD can have 10-15% advantage for the next couple years, but 2x-3x? That's never gonna happen.
