There's a lot of speculation about the SoC used in Samsung's Galaxy S II,
thankfully through process of elimination and some snooping around we've been able to figure it out.
We know for sure it's not NVIDIA's Tegra 2 or Qualcomm. That leaves Samsung or TI.
A quick look at GLBenchmark2's output gives us the GPU string: ARM Mali 400.
TI's OMAP 4 uses a PowerVR SGX, so it's out of the running. This leaves one and only SoC:
Samsung's own Exynos 4210 (formerly Orion).
Exynos has two ARM Cortex A9 cores running at 1GHz. As a result, general performance
of the Galaxy S II is competitive with phones based on NVIDIA's Tegra 2.
The Galaxy S II runs Android 2.3.1 compared to 2.2.1 used by the Tegra 2 phones,
and as a result has better Javascript performance which we see in some of our benchmarks.

The GPU accelerated UI used in Android 2.3.1 makes the Galaxy S II feel a bit faster than the Tegra 2 phones,
however that's not always the case. While web page loading feels comparable between the Atrix 4G
and the Samsung Galaxy S II, Tegra 2 appears to handle flash a bit better than Samsung's Exynos.
This is a pretty significant difference in our Flash benchmark, however it does translate into
a somewhat less smooth experience when scrolling around web pages with Flash.
We managed to run GLBenchmark2 on the Samsung Galaxy S II and compared it to our recently
reviewed/previewed Tegra 2 smartphones.
The Mali-400 MP performs pretty well in GLBenchmark2, however it's still a bit behind NVIDIA's Tegra 2.
Note that the Galaxy S II runs at 800 x 480 so its direct competitor in this case would be the Optimus 2X.
These results don't tell us a lot about the GPU's performance other than the combination of hardware and
drivers isn't quite up to par with what NVIDIA has today - at least under GLBenchmark2.
There's so much that can be done with driver optimizations that it's difficult to draw any meaningful conclusions yet
