Troubleshooting • Re: Pi5 8GB memory bandwidth significantly lower than Pi5 4GB

Still about 10% slower than the 4GB pi5
Using single threaded runs (non OMP).
Can you explain what you ran?
After the busybox command I'm not really seeing a difference in 4G and 8G for either:

Code:

gcc -O3 -march=native -mtune=cortex-a76  -fopenmp stream.c -o streamomp.10Mtaskset -c 0-0 ./streamomp.10M 
or

Code:

gcc -O3 -march=native -mtune=cortex-a76  stream.c -o stream.10M./stream.10M 
There's some noise on the measurements, but it's hard to say which one is consistently higher.
