The P400 does not have a faster GPU though, then clock increase is limited to the CPU, so none of the main demos I am working on right now are going to be any better or worse than a standard Pi4.. Its going to take something with more CPU based needs to really get the P400 showing off what it can do.
Though if the overlcocks on the pi400 turn out to be stable, and it did seem to be ok when I ran them on the broken one.Then indeed its performance goes up quite a bit.
I had the CPU at 2200 and GPU up to 750 which was extreme, I think its 400ghz normally? It had no issues running any high end GPU demo's at all, suggesting it can comfortably cope. But I didn't have the system long enough to keep it at those rates, and generally I don't reccomend overlcocking to gain performance. Better coding is a safe solution
But it certainly suggests the Pi400 is going to be a pretty amazing machine to squeeze power out of.
Is there anyway to change the clock speed in a running program?
