Out of curiosity, what is your power consumption and thruput if you lock the graphics clock to base clock (nvidia-smi -lgc 1530)?

You can reset graphics clock by nvidia-smi -rgc afterwards.

This is wrong.

y does not have to divide k.

2*k*p = y(y + 2) = 2*k1*p*(y+2)
Therefore, k = k1*(y+2). i.e. Only k1 needs to divide k

p*(k/y - k1) = 1 ==> For this we need that p*k/y be an...

Current wavefront is > 5M (5.5? 6?). 5.5M FFT = 44MB + overhead. So your statement will work if it was 64MB per chiplet. Still, that ought to give non-trivial IPC improvement over Zen 2
