Hi Vipin, In my opinion, 3% difference is probably not something to worry about. However, there could be many reasons for the difference. As SE mode will use predefined memory address mapping, and thread schedule, that might cause differences compared to the full-system mode.

If you are using the same memory system configuration for both modes, the memory controller clock should be the same and not impact the difference you are observing (in my opinion). -Ayaz On Fri, May 26, 2023 at 7:16 AM VIPIN PATEL via gem5-users < gem5-users@gem5.org> wrote: > Hi All, > > > I ran the attached microbenchmark (test1.c) with gem5 in FS and SE mode.
