General discussion • Re: A Pi Pie Chart

I see that you do not have Orange Pi 5 plus listed. It appears to be slightly faster than opi5. These are the resuts:

Code:

Thanks for the report! The earlier Orange Pi 5 results were provided at

In that post it was claimed the simpler RK3588S was manufactured using a 6nm process while the RK3588 in the plus uses 7nm. My impression is they should perform the same provided the clock speeds are the same.

I wonder if the speed improvement results from a newer C compiler rather than hardware differences. The performance differences could also also result from memory allocations with unlucky cache-line alignment or noise from various Linux background tasks.
