## What is the formula of Data transfers between CPU and memory sub-system (total traffic, including L1, L2, LLC and DRAM traffic)?

I can compute GLOPS based on #instructions and instruction type.

For example, I have 17694720000 FMA3, so I have 17694720000*3*8*3*8=283GFLOPS. Great! Intel advisor gives the same number.

However, how to get Data transfers between CPU and memory sub-system (total traffic, including L1, L2, LLC and DRAM traffic)? (The number in the bottom right. It does not match with #instructions for memory load.
