I had been reading a little about the CPUs that has build in graphics capabilities (GPU) and have a doubt:

that integration does not means more heat generation in the CPU?

Are not they going again to the heat disipation limit in this integrated CPU/GPU?

something like the practical speed limit of the Prescott one core CPUs that ends up in the bird of the multicore processors due to the high consuming - hugh heat generation of the extremely integrated one core CPUs

Look at a lot of game consoles.. like Play Station and Xbox. No dedicated graphics processor, all done with a multi-core CPU.
And for any motherboard with on-board video system, the CPU does double duty if only one core.. disseminating and routing data, and also rendering video.
Thermal sensors and limiters are integrated into the core of a CPU. If limits are reached, the core will throttle back.

If there had been no advance in the transistor-fabrication techniques, yes, we would be seeing something like that happen again. However, it would be perfectly possible to build even faster Prescott one-core CPUs with the transistors that we have today. They are that more efficient.
