That doesn't make sense to me. Apple was starting from scratch (well, from PA Semi, which made Power not ARM), but Intel and AMD have been designing high-performance CPUs for decades, and already changed architecture (to AMD64) successfully. On top of that, both have experience with ARM processors.
- dmitriid 4y agoIt takes around 4 to 6 years to design a new processor even if you have experience with it. A new competitive processor in an area where all you have is "some experience"... Well, I wouldn't hold my breath. If (and that's a big if) AMD and Intel started looking into ARM seriously after Apple unveiled M1, I wouldn't expect any ARM processor out of them earlier than 2025-2026. Funnily enough I'd expect Amazon to perform better in this space (Graviton has been in deployment since 2019, three years ago, and is now in its third iteration).
- fmajid 4y agoI would only take it seriously if Intel tasked this to its scrappy Israeli R&D, which saved the company from Itanic and Netburst irrelevance.
- formerly_proven 4y agoAMD had K12 (Zen for AArch64)
- dmitriid 4y agoNever released. They did have an Opteron A1100 which was 3 years later than its orginal announcement date (released in 2017, announced for 2014)... and somehow I couldn't even find proper overview of its performance. So AMD hasn't had much in the ARM department in the past 5-7 years.
- snvzz 4y agoBut we don't know what they have unless they announce it. My guess is that they kept an ARM Zen frontend working, internally. And they probably have a RISC-V frontend now, alongside many other projects. They are large enough to do so. When they perceive they can launch a successful product, they do so. Otherwise, we never know of these efforts.
