![]() ![]() GLBenchmark gets around vsync by rendering offscreen, so the 4S is allowed to run as fast as it can. We have since updated the charts to reflect the 4S' actual performance. We had two sets of graphs, one internal and one external - the latter had incorrect data. The performance gains live up to Apple's expectations ( Update: our original 4S for Egypt/Pro were incorrect. ![]() While there are other reputable 3D benchmarks, GLBench remains the only good cross-platform (iOS and Android) solution we have today. GLBenchmark continues to be our go-to guy for GPU performance under iOS. The lower clocked GPU goes along with the lower clocked CPU in the 4S' version of the A5 to keep power consumption in check and because the platform doesn't need the performance as much as the iPad 2 with its higher resolution display. There are 28% more pixels to deal with on the iPad 2 vs the iPhone 4S and 9x vs 7x actually works out to be a 28% increase. The iPad 2 has both a larger battery and a higher resolution display. ![]() Apple claims the iPhone 4S can deliver up to 7x the GPU performance of the iPhone 4, down from 9x in the iPad 2 vs. The A5 in the iPhone 4S gets the same GPU, simply clocked lower than the iPad 2 version. The increase came through more execution resources and a higher GPU clock. Apple boasted a roughly 9x improvement in raw GPU compute power over the A4 into the A5. In our iPad 2 review I called the PowerVR SGX 543MP2 Apple's gift to game developers. ![]()
