Hello,

I am evaluating two packages, name them program A and program B. In program A, Intel Advisor reveals a DRAM roof with bandwidth 39.98 GB/s. In program B, I see a DRAM roof with bandwidth 21.12 GB/s. My laptop computer has an Intel i7 11800H, which has a peak bandwidth of 51.2 GB/s. My first query is, why is Advisor measuring completely different bandwidths for various packages? Should not this simply be a characterization of my laptop computer, and never this system? Second, ought to these measured portions be nearer to the rated peak of 51.2 GB/s?

I connected screenshots of program A and program B beneath, titled program_A.png and program_B.png, respectively.
