A deactivated iGPU will generate no heat, thus the CPU can clock (itself) higher and/or will run cooler, or am I seeing this wrong?
Ryzen has such a high thermal ceiling of 91*C that a deactivated GPU will not make any difference unless your cooler is already inadequate.
No I don't see this on my 2200G.
It hits the same speeds, but it doesn't thermal throttle ever even with the stock cooler.
AMD stock coolers are not like Intel ones and the chips don't thermal throttle.
