Macrumors published an Anandtech link that demonstrates the performance improvements of the A15. Apple claimed the A15 was 50% faster than the competition, and Anandtech called them out for "lying" (my word, not theirs). It turns out the A15 is actually 62% faster, not 50%. And the new GPU is "absolutely astonishing", and that is a quote!
Double system cache (same size as M1)
50% more L2 cache
Better power efficiency
New CPU microarchitectures
Downside: More throttling, but apparently the danged thing is so fast
even when throttled that it crushes the competition!
I'm super excited for the M1X / M2X or whatever Apple calls the thing we all know is coming in a few weeks.
