A question....

The eSRAM clock runs at the GPU clock or it can run async?

That is a good question. I think you have to consider both cpu and gpu. But generally it's ok if memory is faster than the fsb of cpu/gpu - it just must not be lower...

For 192GB/s you have two options... 750Mhz or 1500Mhz... but MS are saying they can read and write at the same time so that give us 750Mhz for eSRAM.

Or the eSRAM runs at lower clock of GPU.... or the GPU is running at 750Mhz too.

I think (no sure too) that the CPU runs at 2x the GPU clock in AMD APU (not a rule but in most case run in that config).
