Low Power cpu/mobo questions

The AMD Fusion APU C-60 is basically crap. I'm pretty sure you will have a hard time playing the Sims 3 on that thing. Forget BF3 and BF4 altogether.

I would look at mounting a laptop. It is built with relatively low power components already and there is a lot of buzz coming out regarding AMD's Richland APU and Intel's Haswell CPUs. Both are expected to have relatively decent increase in CPU processing power compared to the current generation APU / CPU. However, it is on the integrated GPU side that gets the most performance boost.

The Radeon HD 8670M is expected to be 20% to 40% more powerful than the current Radeon HD 7660M in the Trinity APU. However, just over the weekend I found info that the best performing Richland APU will come with the Radeon HD 8690M. How does it compare to the HD 8670M or the HD 7660M? I have no idea. To give you a sense of it's performance (and this is in my opinion after doing some extensive research and calculations) the desktop version of the Richland APU with the Radeon HD 8670D integrated GPU would a slightly faster (5% - 10%) than the desktop Radeon HD 5670 graphics card if the performance increase is 20%. If the performance increase is 40% then I would rate the Radeon HD 8670D at about 85% - 90% the performance of the desktop Radeon HD 6670. Not sure how the Radeon HD 8690D would rate, if such a model exists. Naturally, the mobile versions will be little slower due to power and heat restrictions.

On Intel's side there's Haswell and the mobile version will have basically 3 different integrated iGPUs; the Intel HD 4600, HD 5200, and HD 5200e. The HD 4600 is only expected to be about 20% more powerful than the current Intel HD 4000 graphics core. That makes it almost as fast as a desktop Radeon HD 5570 (probably 90% of it's performance). The Intel HD 5200 is expected to be up to 100% more powerful than the Intel HD 4000, that means it will be somewhere in between the mobile nvidia GT 625m and GT 630m. Sorry not sure what desktop Radeon HD graphics card they are equivalent to; I haven't researched that. The big surprise is the Intel HD 5200e which I heard about over the weekend. I didn't do any research 'cause I was working on my taxes and studying for an exam that is fast approaching. But rumors have it that it can rival the nVidia GT 650m. Is that true? I have no freaking idea.
