Yes P3MM is also scheduled for massive gains solely due to machine learning, I'll leave the other 2 I spotted here a mystery in case other user's want a go
I have not read much about deep ML applicatuions, not my thing, and that IPC gain was from the recent AMD white paper in shared L1 caches and when some applications need to go huntiing for data that is not private on L1, the benefit of a mesh like sharing of L1 would improve cache misses.
The main benefit for GAMING was BVH, allot of the deep learning stuff is other applications and not directly exciting for gaming with 16 ms frame times.
So it is unclear if the shared L1 is part of infinity cache or if its more DL application and wont be in gaming GPUs. The AMD paper has a seperate section for deep ML.
We shall see as that level of detail was not in the AMD presentation.
