Not too sure that Gerard would want anything to do with Jim again. Or vice versa.
Why is that? Did I miss something?
Are they working with Apple? I thought Apple is suing them?
No. I was emphasising on the "high end ARM chip" part. Nuvia has plans to create the highest end ARM chips for data centers and such. Hopefully that trickles down to laptop size chips too one day. But "high end chips" and laptops don't go hand in hand anyway. The "regular ARM Chips" are already powerful enough to power laptop usage.
If that did happen it’d be the Nuvia ISA based on ARM no? So devices that used their chips would have their spin of the arm arch —- I read that every ARM chip is indeed an ARM chip but each vendor puts enough of their own spin on it that they are different enough — is that the case? If so, it’s unlikely that Apple will use something from them not built in house and custom to their needs imo
Never really used ARM to know whether such disparity exists. Maybe it's similar to that of AVX2 on Intel vs AMD - minor differences but generally things would work across SoCs just fine.
The ISA is defined by ARM, vendors can't directly change it. The actual properties of the chip is up to the vendor e.g. cores, caches, subsystems.
