The A15 shows that M2 should be scaring AMD/Intel. A15 performance cores had significant gains and really improved integer performance all while reducing power consumption slightly. A15 efficiency cores are even more amazing. They got something like 30-40% faster. They are now roughly as fast per clock as the big cores in x86 systems while still using only a fraction of the power of the big cores. This roughly translates into 8 full-size x86 cores, but with 4 of those being even faster. Then there's the massive cache (32mb on mobile and probably 48/64 on M2) to further push down power consumption. They'll also be bumping the GPU by 30% (more if it doesn't throttle). AMD really needs to either pick back up their ARM designs or start heavy investment into RISC-V designs.
