We've noticed a pretty attractive thing regarding to Intel's future Arrandale mobile CPU with IGP as well as that is the truth that it can overclock the graphics core. Intel plans a complete series or Arrandale mobile GPUs in Q1 2010 timeframe with the best ever of them is Core i7 620M that operates at 2.66GHz.

With CPU turbo overclocking this mobile Core i7 will boost its frequency all the mode to 3.33GHz with more exciting is the truth that graphics that works at 500MHz can also overclock all the system to 766MHz.

The top mobile Core i7 the 620M version will appear with a 35W TDP, which is pretty good allowing for the truth that IGP core with memory controller wants most likely some; we guess 12W while the rest is what CPU requirements.
