Smartbench 2011 is one of the few synthetic benchmark tests that are able to measure multicore performance, so these results are for both CPU cores at work. The Samsung Galaxy S II steadily beats the HTC Pyramid in both the productivity (3732 vs 1898 points), and GPU tests (2431 vs 1426 points).
Bear in mind that the Galaxy S II that the test was run on, seems to be the final version, with the 1.2GHz Exynos chipset, and the HTC Pyramid was the internal name of the HTC Sensation when it was still a prototype, so we'll wait for the retail version to pass judgement on the 1.2Ghz Snapdragon chipset inside.
As you can see on the right, we tried our own preview unit of the Samsung Galaxy S, and scored 3346 on the productivity part of Smartbenchmark 2011, and 2076 on the GPU test, but it is clocked 20% lower than the retail version, at 1GHz for each core.
Thanks for the tip, Philip!
