Following yesterday's introduction of the iPhone 5s, a new GFXbench result showing partial graphic benchmarking results has appeared revealing significant improvements compared to the iPhone 5 on the Egypt HD 2.5 test (via @nerdtalker and @anexanhume).
Comparison of iPhone 5s and iPhone 5 graphics benchmarks for Egypt HD 2.5 test
Certainly there are some caveats associated with the benchmark given that it includes only a single test and a need for developers to optimize their apps for the new 64-bit A7 architecture with support for OpenGL ES version 3.0 in the iPhone 5s will undoubtedly yield differing levels of improvement in real-world situations. Still, based on this single snapshot it appears the graphics performance will indeed see a significant improvement in the new device.Article Link: Early Graphics Benchmarks Show Significant Boost for iPhone 5s
