Is the 120Hz display fully adaptive like Gsync/Freesync, or is it only at fixed rates, 120, 60, 48, etc?
Their last one only did 30 or 60.
Yeah, even accounting for the third high-low core pair it's 1.5MB a core to 2.6MB. Probably part of what allows that per-thread performance gain without hitting more battery life. And with all 3 cores performance also doubles, 30% by Apple was very conservative.
They're also sharing L2 with the GPU I think, helps there too.

A9X vs A10X.
Btw the iPhones have an L3 cache as well, 4MB L3, 3MB L2, so the A10 in the iPhone 7 was already at a staggering 7MB for a phone. If you look at big desktop CPU cores we're not incomparable anymore (at lower clocks of course).

.. So I just looked it up also, and it looks like this L2 cache has increased from 3 MB to 8 MB - this difference seems quite extreme? I read briefly about the topic, and apparently it is highly essential to performance, due to CPU speeds having developed faster than memory access speeds - sound like this boost could have quite dramatic implications for performance?
