This was clearly not a very well functioning sample system. It's no surprise that the GPU results look unimpressive if memory bandwidth drops by 20%. But also you can't expect miracles -- HD4600 appears to only have a 25% increase in the silicon budget over HD4000. (I am a bit bummed that the earlier rumors of GT3 being mobile only appear to really be true.)
