It’s time to put the Exynos chipset to the test – both the CPU and the GPU. We’ll be using the Optimus 2X, which uses Tegra 2, for comparison. Both chipsets are running at 1GHz so we’re expecting similar results (the underlying ARM architecture isn't all that different between the two).
Keep in mind however that the Samsung I9100 Galaxy S II should launch with its chipset clocked at 1.2GHz, which should give it the upper hand.
We ran our standard batch of tests – here are the results.
The CPU performance of both Exynos and Tegra 2 seems pretty well matched – Exynos takes Linpack, Tegra 2 takes Benchmark Pi and they’re about equal on Quadrant.
It’s the GPU performance that surprised us though – the Mali-400MP GPU seems 20fps slower than the GeForce. We’re guessing that’s a software cap (like the one the original Galaxy S had) since the framerate always stayed at just under 60fps.
We ran a few games too – one had issues (that’s what you get for testing on pre-production software) but the other ran perfectly. The next section of this comparison has more on the real-world feel of the Samsung I9100 Galaxy S II.
