The Samsung GT-I9300 Galaxy S III benchmarks were found on the website of GLBenchmark, left there by a careless tester, and snapped by a smart man. The chipset appears to be a Exynos 4412 clocked at 1.4GHz, which comes with an ARM Mali-400 GPU, but clocked at 400MHz, making it 50% faster than the current edition in the Galaxy S II.
The graphics boost is low when compared to the 5 times boost offered by the Exynos 5 chip which is being designed for the next gen of Samsung Tablets.
At the current state the benchmark results outweigh all current gen devices including the One X, S4 chipset the iPhone 4s and the iPad 3. The finalized version may further be tweaked to take on the possible next gen iPhone with the A5x chip.
