The Samsung Galaxy S3 is no slouch as expected and early tests show that the quad core Cortex A9 processor that powers it (as well as its Mali400/MP4 GPU) surpasses all its ARM-based competitors including its only quad core rival on the market, the HTC One X.
Tech website Anandtech put the smartphone through its paces using a number of benchmarks, namely SunSpider, Browsermark, Vellamo as well as GPU-bound GLBenchmark 2.1 and RightWare Basemark.
Browser and CPU performance are very good although some of the advantages can be attributed to tweaks made by Samsung for the phone's browser and the fact that it runs on Android 4.0.4 Ice Cream Sandwich.
The phone's real forte seems to lie in its GPU. In Anandtech's own words, the GPU of the Galaxy S3 is "insanely fast" on par wih the HTC One S and the Galaxy S2 and far ahead of the One X which uses a quad core Nvidia Tegra 3 processor and the iPhone 4S which uses a dual core PowerVR SGX543MP GPU solution.
It's likely that Samsung has significantly raised the GPU core clock speed which is made easier because it used a 32nm LP manufacturing process to fab the Exynos 4412 and it would be interesting to see how this affects battery life and power dissipation as well.
