I ran some GPU benchmarks between the MacBook Air 11" and MacBook Pro 13". Both have the GeForce 320M integrated GPU but the MacBook Pro runs the OpenCL and OpenGL benchmarks from 14% to 43% faster. Though the 13" MBP is running at 2.4GHz and the 11" MBA is running at 1.4GHz, these are pure GPU tests (SmallLux OpenCL benchmark and OpenGL Extensions Viewer). Both are connected to a power source so there should be no down-clocking going on to save the battery. Thoughts?
