There are a lot of nice things in arm. Ie slightly less register renaming.
For example, Jim Keller estimates a fully developed arm chip will be 15-30% more efficient than an equivalent x86. Now, this development hasn't happened yet, but with giants like Qualcomm, it will happen eventually.
- AlphaSite 10y agoIf this was the case (and there weren't other issues e.g. insturctuon fusion etc) then wouldn't AMD be pushing K12 far harder? It's the same ceneteral core as Zen but they don't seem to have as much confidence in it.
- deepnotderp 10y agoBecause migration is super expensive and a big part of what's preventing the movement to ARM servers. Also, the aforementioned case hasn't necessarily happened, Keller has spent forever making Zen better. They are still working on K12 IIRC, but Ryzen, for good reason, is the focus. Besides, CPUs are more and more becoming simply host systems. Besides, never doubt the word of jim keller ;)
