  érdekesség ; AMD ( Forrest Norrod ) intervjú. ( bár 1 hónapos, nekem új )

  https://www.nextplatform.com/2022/10/03/the-steady-hand-guiding-amds-prudently-expanding-datacenter-business/

  mi a valószínűsége ARM-os AMD által gyártott szervernek?
  TLDR: nem zárja ki a lehetőséget, ha az ügyfél nagyon kéri ... de szerinte az ARM ISA-nak kb csak 5% előnye lehet, amit ellensúlyozni lehet ...

  Second bonus question: What about the people who are trying to nudge you back into making Arm server CPUs? Ampere Computing has gotten traction, AWS and Alibaba are doing their own Graviton and Yitian Arm CPUs. You can obviously do it, and do it well.

  Forrest Norrod: I’ve been highly skeptical of Arm in the datacenter for a long time. But I think that legitimately, finally, there’s growing and real interest in Arm. But I think also as well that people are starting to realize there’s no magic instruction set architecture.

  There was this long belief that Arm was substantially more power efficient than X86. Now, ARM processors tended to be designed for much lower performance. And, and I can tell you that we got pretty far along with an internal Arm design, and it was very, very clear that you if you’re delivering a certain level of performance, the delta in power driven by the ISA is like 5 percent. That’s less than the impact of the quality of the physical design team.

  But some customers want Arm as an option in their datacenter. And, we’re open to it. We’ve got a custom chip business, and we do custom chips for a variety of different folks. And, you know, we’re, we’re not wedded to be, once and for all, the X86 processor company. We had to make tough choices eight or nine years ago because we could not divide our focus. We would not have gotten to where we are right now – absolutely – if we had not focused.

  If customers really wanted an Arm server chip from us, we’re not opposed. We have done it, and we know how to make it not only do the core, but more importantly, we know how to make an ARM core fit into our ecosystem. And we deploy plenty of Arm. In the there’s a lot of Arm cores in our game console chips. There’s a lot of ARM cores now in our Pensando DPUs and our Xilinx FPGAs. Arm is a good partner and we’re going to use Arm wherever it makes sense. And if customer demand is there, I have no problem with supporting whatever instructions set architecture customers want.
