Performance - Part I
Benchmarking the Samsung Galaxy S II
We have adopted a few benchmark tests specific to the Android platform for a few reasons. With the Google Android platform maturing so quickly, choosing a suitable phone in a growing sea of Android devices with close to identical specs is extremely difficult. To add on, with manufacturers jumping on the dual-core processing bandwagon, these results will give a gauge of how they will fare against their lesser endowed counterparts. Hopefully, these benchmarks will allow for a clearer picture on which smartphone is worth your while.
Within this page, we'll be looking at two specific benchmarks, both of which are downloadable via the Android Market.
- Quadrant: It measures the device's performance based on its CPU, I/O and GPU. Simply put, Quadrant is a benchmark that gives you a general idea of how your device performs against other Android devices.
- NeoCore: It is targeted towards the device's GPU performance. This is especially important given how smartphones of today have evolved into an alternative, high-powered device that dabbles in heavy graphical interfaces and gaming.
Do note that the above two benchmarks are not absolute in measuring performance, but they give you a good rough estimate of how the device performs. Our tests were conducted on devices from a fresh reboot on a stock firmware. To show how the Samsung Galaxy S II performed against similar smartphones, we compared its results against the following high-end Android devices - LG Optimus 2X, Motorola Atrix, and Samsung Galaxy S.
|Device||Samsung Galaxy S II||Motorola Atrix||LG Optimus 2X||Samsung Galaxy S|
|CPU||ARM Cortex-A9 Exynos
(Dual-core 1.2GHz )
|NVIDIA Tegra 2

|GPU||Mali-400MP||ULP GeForce||ULP GeForce||PowerVR SGX540|
|OS||Google Android 2.3||Google Android 2.2||Google Android 2.2||Google Android 2.1|
The Samsung Galaxy S II boasts better scores than its predecessor. No surprises there since it comes with more than twice the CPU power (dual-core vs. single core) and almost twice the RAM capacity. The Galaxy S II is also loaded with the latest Google Android 2.3 OS, which is further optimized for performance. Having the best hardware specifications out of the lot, it managed to beat the 1GHz dual-core smartphones from Motorola and the LG in the Quadrant benchmark scores. Though the Motorola Atrix came closest in terms of specs, it still lagged significantly behind the Galaxy S II.
However when we take a look at the NeoCore benchmark scores, the Galaxy S II's score is actually within the same range as the Motorola Atrix and Samsung Galaxy S, possibly due to a capped framerate. Though the LG Optimus 2X scored higher with its uncapped frame rate, this isn't a definitive indication of the graphics performance on the Galaxy S II.
Equipped with a dual-core ARM Cortex A9 1.2 GHz, the latest Mali-400MP GPU and ample amount of RAM (1GB), the Samsung Galaxy II is nothing short of a speed racer. As a result, we found no problems with its performance as it ran smooth and loads apps extremely swiftly. We experienced no lags and crashes in performance while surfing the web, navigating on the phone and running various apps during our test run.
