Intel's having to find and fix every place their drivers assumed that the CPU's RAM and the GPU's RAM were the same pool of memory. As a result, it's completely unsurprising that they're struggling with performance in real applications and games, but it doesn't provide a reason to expect microbenchmarks such as these to run afoul of an irrelevant problem.
