3D performance - GLBenchmark 2.5.1
GLBenchmark 2.5 gives a good impression of the 3D performance of mobile phones. It's clear that the iPhone 5 is superior here as well. The most fair comparison is provided by the offscreen test, in which all phones render a frame buffer with 1920x1080 resolution. The phone's own resolution has no influence on the results. As you can see, the triple-core version of the PowerVR SGX543MP GPU from the iPhone 5 is much more powerful than the boosted Mali-400 MP quad-core GPU in the Samsung Galaxy S III and Note II.
CPU and memory performance - Geekbench
Geekbench is a cross-platform benchmark that tests several aspects of a phone. These include integer and floating point processor performance, memory speed and memory bandwidth. Geekbench shoes that in terms of pure processing power, the Exynos 4412 quad-core processor in the Samsung smartphones is more powerful than the dual-core Apple A6 processor. The difference isn't huge, especially considering that the Note II has twice the number of cores, and a clockspeed of 1600 MHz compared 1000 MHz of the iPhone 5.
Apple's memory and access speed are very good, indicated by the Memory and Stream benchmarks in Geekbench. The iPhone 5 remains far ahead of both Samsung models.
When we look at the total score in Geekbench, the Galaxy Note II comes out on top. The Galaxy S III and Apple are about on the same level.
We will end this first comparison with the specifications of the Note II and the iPhone 5. In the coming days both phones will receive a full in-depth review here on Hardware.Info.
