The dev kit was rumoured to run the cpu's at 2ghz but retail is expected to be 1ghz both portable and docked. If only they could push that a bit higher like 1.2 or 1.4ghz it will make a huge increase in performance. Personally while I understand its the gpu does almost all the work when increasing the resolution between portable and docked performance you'd still think docked would get a small cpu increase maybe 1.2ghz. Disappointed with the docked performance that has been shown so far.
I understand its because portable and docked must run the same games exactly apart from resolution output but with no battery power restriction its a shame there isn't a high performance mode for developers that want to use it, i.e. 2ghz cpu speed in addition to the gpu speed boost. I suspect its all going to be down to memory bandwidth which was predicted to be 25.6GB/s and shared between cpu and gpu. This might be ample for portable mode but a bottleneck for docked hence the difficulty of getting to a native 1080p for many games and so pointless increasing other clocks that puts further pressure on the low memory bandwidth.
