...investigation of the bug showed it could be replicated on AMD chips if a person runs cmd as an admin and then pastes in the following command line, "bcdedit /set {current} useplatformclock No". However, the bug on AMD only affects the Windows 8 PC during its next boot. After that, the OS resets the "useplatformclock" choice back to "Yes". This apparently does not occur when used on a Windows 8 PC with an Intel processor.
This new information was apparently enough for HWBot to ban all Windows 8 AMD benchmark scores. In fact, the only scores that will be allowed in their database will be from "non-overclockable notebooks"; Microsoft has yet to comment on HWBot's decision.
HWBot now banning Windows 8 benchmarks from AMD as well.
