Some of you are totally wrong about Ivi-bridge GPU. The open source driver gives an equal performance with a 500gflops Radeon with Catalyst, but that is not all. You can overclock IvyGPU almost twice 650mhz to 1250mhz, that is not possible with AMD and Nvidia mobile products because they are drain 50watts when IvyGPU drains 5-10watts, so you may have an open source Teraflop. Also Intel gives the same GPU for Celleron and Pentium to, and farther more gives CPU cores for GPU acceleration as ARM and CELL does, that is at least +200-300macGflops for every IvyCore@3ghz. SandyGPU is 2-2,5 times slower. The actual SandyGPU and IvyGPU is an Imagination PowerVR mp6-mp16 (tile graphics) based on ARMmp-Core, that is the company with OpenRL and with many ARM design. An Ivy SlimLaptop usually Celleron or Pentium probably starts from 350box at least in my country and a PicoUnit from 200box or less, so I will not buy another Nvidia or AMD GPU from now on.
