iPhone 4S Wins in most Benchmark Test compared to Samsung Galaxy, iPad 2, and Others

in iPhone 4S by

AnAndTech provided several benchmark results of iPhone 4S compared to several devices including Apple iPad 2, Samsung Galaxy S II, iPhone 4, iPhone 3GS, Nexus also several other devices.

It clearly shows that iPhone 4S vs Samsung Galaxy S II is not comparable because iPhone 4S always win in overall tests. But compared to Samsung Galaxy Tab or iPad 2, iPhone 4S was a bit lower somehow. Apple is shipping a lower A5 chip in the iPhone 4S than the A5 chip in the iPad 2 to make the iPhone 4S has a much battery life.

Note that we always run our benchmarks on a stock OS/browser configuration.

A lower clock not only means higher yields from the factory, but likely a lower operating voltage as well. Dropping a CPU’s core voltage, yields a greater-than-linear decrease in power consumption, making the marginal loss in clock speed a good choice. At a lower operating frequency than its Android competitors, Apple does have to exploit its strengths in software to avoid any tangible performance penalties. Apple has traditionally done this very well in the past, so I don’t expect the loss of frequency to be a huge deal to the few who do cross-shop iOS and Android.

Unsurprisingly, memory bandwidth doesn’t appear to have gone up either compared to the iPad 2’s A5 (taking into account scaling due to CPU clock increases). The Samsung part number on the iPad 2’s A5 indicates two LPDDR2-800 die on package, it’s safe to assume that whatever Apple clocked the memory interface at in the iPad 2 remains unchanged in the iPhone 4S.

The GPU results tell a similar story courtesy of some early GLBenchmark 2.1 results. The 960 x 640 results are useless as they are bound by vsync at ~60 fps. Luckly GLBenchmark 2.1 added an off-screen render mode at 1280 x 720 where we can really see the differences between the iPad 2 and iPhone 4S A5 implementations:

Here the iPad 2 holds a ~21% performance advantage, which once again I assume to be all related to clock speed. Also note the huge advantage over the existing iPhone 4. The GPU power in the 4S should be more than enough to run any well written, current generation title at well north of 30 fps on its display.
