That information changes with every application. Literally every single program in the world has its own cache characteristics.

I suggest learning to read performance counters, so that you can get information like this yourself! L3 cache is a bit difficult for AMD processors (because many cores share the L3 cache), but L2 cache is pretty easy to work with and profile.

General memory-reads / memory latency is pretty easy to read with various performance counters. Given the amount of latency, you can sorta guess if its in L3 or in DDR4.
