AMD claims +35% IPC improvement in AES subtest of Geekbench 6. It's not the entire Geekbench 6 CPU suite. It's deceptive.

Overall GB6 improvement is likely around 10-15% only because that's how much IPC improved while clock speed remains the same.

Apple themselves have around 10% IPC uplift with M4 too.

The real issue is that most code people run doesn't use very much SIMD and even less uses AVX-512.
