Remember that challenge for a FRAPS equivalent in OS X from the rMBP review? Unfortunately neither SC2 benchmark provides particularly good results for the HD 4000. In a further bout of backwardness, our SC2 CPU tests end up being more GPU bound on the MacBook Air which yields significant performance improvements. These benchmarks only end up GPU bound at higher resolutions it seems. Starcraft 2 shows very little progress over the 2011 MacBook Air in the GPU tests, mostly because we're actually CPU limited here. Similarly strong performance is available under Half Life 2 Episode Two. More important is the fact that the 2012 MacBook Air finally delivers better GPU performance, across the board, than the 2010 MacBook Air did with its off-processor NVIDIA GPU. The bad news is neither is really fast enough to drive higher resolution external displays, but you can get reasonable performance in many of the hot titles on OS X today - at native panel resolution.īoth models deliver over 60 fps in Portal 2 at 1280 x 800. There's no real difference in GPU performance between the 11 and 13-inch MacBook Air, they both have an HD 4000 on-die and both perform pretty similarly. In these thermally constrained environments, Intel's HD 4000 does its best to shine compared to the 3000. Similar to last year, there's no discrete GPU option. All of the 2012 MacBook Air models use Intel's HD 4000 processor graphics.
