RK3566 - 512KB L2 cache.
Apple M1 - 12MB L2 cache Big / 4MB L2 cache Little.
Whopping cache is one of the main reasons why M1 is so fast.
Large caches are great, there's no doubt about that, but...
Small caches are almost certainly one of the reasons why RockChip is able to make and sell relativey inexpensive SoCs. Large caches (i.e. large amounts of SRAM) require a lot of transistors and, in general, reduce the yield, which translates into much more expensive chips.
