The 780G gives weak gaming power on the MINIX board supported by 128MB DDR2 sideband-memory, but compared to VIA or Intel chipsets it's way ahead.
Of course we could not resist to put an HD3870 in our board and run 3DMarks. Compared to the same tests we did with the Nano platform AMD is leading clearly; of course, we tested with the dual-core only.
While the AMD Athlon 64 2000+ is not that impressive, because there is no Cool'n'Quiet, the AMD Athlon 64 X2 3400e can match its little brother in power consumption. Both AMD processors on the 780G board have the same idle power consumption as Intel's Atom/945GC platform. Under load we did not expect AMD to catch Atom, but the single-core is quite close, the dual-core at least matchs the single-core Nano. Even with a HD3870 the AMD platform is quite close to Nano, although it's dual-core and about three times faster.
The HD3xxx tests show maximum consumption, while the others show average consumption.
