@steve@discuss.systems @regehr@mastodon.social Anyway, take that with whatever amount of salt you want, but Intel and AMD both are strongly incentivized to seriously look at this.
They for sure would prefer to sell you x86s because they have decades of experience with that, but they're looking at what it costs them to do it both in capex and in how much it hurts the resulting designs.
And for the latter, the consistent answer has been "a bit, but not much".

@steve@discuss.systems @regehr@mastodon.social If they really felt it was a lead anchor around their necks, they would've switched. AMD did a serious push on a high-end ARM core something like 15 years(?) ago, and ultimately decided against continuing it, because they didn't think it was a compelling product. If they'd gotten magic sauce huge wins just from the different ISA, I don't think they'd have canned it.

@rygorous@mastodon.gamedev.place @steve@discuss.systems I've seen part of a convincing / complete formal spec for x86 and I would run away from any effort to validate an implementation of this
