The M4A785TD-V, powered by a X3 720 processor was tested at stock speeds and
underclocked to 1.6 GHz with the lowest stable voltage possible (in our case,
1.025V — the BIOS limit). Running at 2.8 GHz, the onboard IGP breezed through
our video playback suite with CPU usage topping out at 40% during our high bitrate
VC-1 clip. Underclocked, VC-1 playback used a few more CPU cycles but the clips
were still rendered with relative ease. H.264 playback when underclocked resulted
in lower CPU usage because we disabled Cool'n'Quiet — at stock settings Cool'n'Quiet
set the clock speed lower than 1.6 GHz.

With the same hardware underneath the hood, the 785GM-E65 delivered nearly
identical results during video playback. The MSI board however exhibited much
lower power consumption, especially when idle. It also used less power when
underclocked/undervolted, though MSI's BIOS allowed us to undervolt further,
0.940V compared to 1.025V on the Asus board.
