iPhone 4S Test Notes: Browser Benchmarks (Versus the Fastest Android Phones) [IPhone]

The iPhone 4S is faster than the iPhone 4. How much faster? And how much faster than its non-Apple kin? We did some benchmark bench pressing to find out. Feel the burn!

First, some synthetic benchmarks, courtesy of Sunspider. How fast could these phones crush JavaScript? We tested each phone on the same Wi-Fi network, inches away from one another. A lower score (faster) is better:

iPhone 4S: 2237.8 ms
iPhone 4: 3611.8 ms
Droid Bionic: 3963.9 ms
Samsung Galaxy S II: 3523.2 ms

The iPhone 4S is the champ by a wide stretch—and its little brother still beats the beefier Bionic.

But what about some non-synthetic testing? We loaded up two popular, image-heavy sites under the same conditions. Again, lower is better:

iPhone 4S
Awl: 6 sec
NYT: 5 sec

iPhone 4:
Awl: 7 sec
NYT: 8 sec

Droid Bionic:
NYT: 12 sec
Awl: 13 sec

Samsung Galaxy S II:
NYT: 5 sec
Awl: 8 sec

Again, the 4S crosses the finish line first. Is this a completely comprehensive test? No. Is this highly indicative? Yes.

If These Early iPhone 4S Benchmarks Are Legit, It's Pretty Fast [Guts]

AnandTech has dug up some apparent benchmarks for the iPhone 4S, which they found around different benchmarking sites and believe to be true. Judging from the numbers, it seems like it'll be one of the most powerful mobile devices around.

Overall, these early benchmarks show the iPhone 4S is less powerful than the iPad 2. But it's superior to every other smartphone—the Samsung Galaxy S II and the Motorola Droid Bionic being the best of the bunch— and equal to Samsung's Galaxy Tab 8.9.

In terms of hardware, AnandTech has determined that Apple is underclocking the A5 chipset to ~800MHz and running a slower GPU than the iPad 2. And in case you're wondering why Apple likes to underclock their chips here's why:

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.

Even with the rumored 512MB of RAM, the iPhone 4S is shaping up to be a beast. [AnandTech]
