I would assume that 256-bit vector processing is much faster on x86 hardware already since that really isn't a thing on mobile hardware. There are also scenarios where AMD's implementation of SMT in particular makes Zen2 much more attractive. For example, I can easily clear an MT score of 14000 in Geekbench 5 on a 3900x with clockspeeds sitting in, I dunno, the 4.2 GHz range? An A13 with 2 Lightning (2.66 GHz) and 4 Thunder (??? GHz) cores scores a measily GB5 MT score of 3400-3500 (varies). I have twice the cores and . . . I guess ~57% (or more) of the clockspeed of an A13, but better than 400% the MT performance. Take two A13s, jack up their clockspeeds by +57%, and you get an MT score of around 11k (hypothetically). Yeah my 3900x sucks power, but big deal. Let's see Apple scale that A13 up to a 95W TDP (or higher).how is it possible for current x86 models (zen 3k, cfl, next icelake which is better) to reach the IPC of a13 while maintaining like 4GHz freq
That ST score is scary, and the MT score may be more a result of throttling than anything else. So A13 deserves a lot of credit. Just not all the credit.
