E-Core equivalent for P-Core's MEM_LOAD_RETIRED.L3_MISS

Hello!

I was wondering, what is the closest I can get to a P-Core's MEM_LOAD_RETIRED.L3_MISS event count, from an E-Core?

I am checking perfom , but given my noobness, I am a bit lost:

Would this be correct:
MEM_UOPS_RETIRED.ALL_LOADS - MEM_LOAD_UOPS_RETIRED.L3_HIT

Thank you!

Hi again!

 

I realized I was mistaken in my initial post. Just because a uop is not an L3 hit, it doesn’t necessarily mean it’s an L3 miss. There could be other reasons, such as the data being loaded from L2.

What I was actually looking for was MEM_LOAD_UOPS_RETIRED.DRAM_HIT

Sorry for wasting your time
