Look hard enough and there are areas in which the performance improvement can be far larger. Intel's new IGPs are armed with various OpenCL improvements, resulting in a near-20-per-cent gain in the LuxMark rendering test. Launching LuxMark on the Sandy Bridge platform resulted in a graphics driver crash; hence the no score.
