I hope there will be power kernel for N9 and N950 too. And I think it will be there for sure.

But let me stress one thing: N950 works so smoothly (by that I mean almost always 60FPS capped by vsync) and reacts so fast that there is really no reason to overclock. I have my N900 overclocked to 1.15 GHz all the time and it is far far worse in terms of speed than N950.

Specs seem to be lower than competition but it is only on paper. In reality N950 is high end device. I will give one concrete example: on N900 resetting tracker database for 3GB of mp3 and 5 movies takes about 10min during which device is barely usable. On N950 the the process takes 30 seconds and there is no visible lag in UI. The only thing that lets me belive that N950 is doing tracker stuff is that tracker processes are visible in top and they eat a lot of CPU.

The GPU in N950 is also the same on paper but I can tell that it is much more powerfull. For example in picture gallery I can swipe through hundreds of pictures at 60FPS with not a single frame dropped. That is a huge bandwidth of texture uploading to GPU. This is not possible on N900 because the bandwith is very limited (I know that because I have done a lot of benchmarks during CloudGPS development).
