So the smart move here for AMD would have been to bin the chips differently according to their tested stability for power usage, like Intel T SKUs. It’s the same chip, but the “X” versions are running at full power (with bios options to turn it down to be more efficient, or aggressively scale power delivery, or what have you), and “E” versions that just always run at lower voltages and currents.

I agree that cutting TDP nearly in half while STILL pulling out a perf gain is remarkable, but also not something most gamers are going to care much about in the context of a desktop system.
