Apple iPhone 4S benchmark tests
Without going into detail, we all know how fast and responsive the iPhone 4S is already by simply playing around with the handset for a few minutes. Due to the simplistic layout and operation of iOS 5, everything moves at a responsive rate and doesn’t exhibit one shred of lag or slowdown as we quickly move around the homescreen. However, to better gauge its processing prowess, we just had to pit it up with the iPhone 4 and run a few benchmark tests to see how much better it is.

Under the hood, the iPhone 4S is packing that glistening 1GHz dual-core Apple A5 processor with 512MB of RAM. Respectable by today’s standards, some might not be all that impressed with the amount of RAM on board with the device, but then again, iOS 5 isn’t the most graphically intensive platform out there on the market.

Running the Linpack benchmark on both devices, we’re astounded by the near instant completion of the test by the iPhone 4S – while its predecessor chugs along finishing considerably longer. Specifically, the iPhone 4S is able to establish itself as the superior device between the two since it’s able to push out 138.22 Mflop/s, which is light years better than the 33.65 Mflop/s score of the iPhone 4. And honestly, the lengthy completion of the test by the iPhone 4 goes to show the speedy nature of the iPhone 4S.

Secondly, we ran a quick graphical test by using 3D Benchmark, which is a WWII style era airplane game test. Mainly due to the game’s less than stellar graphics, the final scores of both devices are relatively close to one another. In fact, the iPhone 4S is able to complete the test in 8.294952 seconds and chugs along at 60.16 FPS. In contrast, the iPhone 4 dishes up a total test time of 8.699314 seconds and an average rate of 57.36 FPS.

Next up, we ran the Comet Benchmark app that shows an animation of a comet running through its trajectory around the sun. Initially, both are able to handle a single comet on-screen at a steady rate of 60 frames per second, but as we crank it up to the maximum 10 comets, we begin to see the raw processing power of the newer handset. Even with 10 comets simultaneously loaded, the iPhone 4S is handling it effortlessly at a consistent 60 frames per second – whereas the iPhone 4 drops down under the 24 FPS mark.

Last, but certainly not least, we ran the interactive and graphically intensive demo of Epic Citadel, which truly showcases the type of experience we’ll get playing some quality games. Initially, it’s very hard to find any differences in performance, but after looking at them both meticulously, the iPhone 4S is still able to produce the smoother response. It’s not bad with the iPhone 4, but there’s a subtle amount of choppiness with its operation.

Why do you keep saying that it's a 1 ghz dual core? It's a 800mhz one. Stop hiding the facts!!

It is a 1Ghz buts its underclocked to 800Mhz.

which would make it 800mhz.

there is no "underclock/overclock" the clock is what its set at.

its only "underclocked" if you get it at 1ghz and underclock it to 800mhz yourself... which is something I do on my galaxyS since it runs smoothly for most things, even at 800mhz.. get that extra battery juice :)

they dont say "this is a 1.5ghz overclocked snapdragon dual core.. they just say its 1.5ghz.

It is still a 1GHz chip underclocked to 800Mhz. It is the exact same processor as on the Ipad.

If I overclock my 3gs, do I claim that the native speed is really the overclocked speed?

I'm the farthest thing from an apple fanboy. I actually plan to get an Android as my next phone. But current Androids running at their advertised clockspeeds, don't even match the 4S's javascript performance(except the galaxy tab). It is not hard to guess that the battery life will be far better with the underclocked 4S.

that is exactly what you are saying. If it's 800Mhz it won't be 1Ghz it's working on 800 so it's 800 not 1ghz if my C2Duo 6420 is on 3Ghz it is 3ghz if it is 2.13 it is 2.13 that's it

No, no, and no.

Snapdragon CPU (the first model, not the subsequent models), was clocked at 1Ghz. As a user there were programs that allowed you to change the multiplier of the clock or change the core clock speed. As the crystal frequency is usually based on the tolerances and build quality of that specific snapdragon CPU in your machine, it is a much safer bet to change the multiplier than to change the clock frequency. As the newer models were released the quality and improvements of that same chip allowed the frequency and multiplier to be adjusted to greater levels. All are still on the same architecture (http://en.wikipedia.org/wiki/ARM_architecture), so the chip is still a snapdragon, but with upgraded components that are rated to a higher clock frequency. It is the same architecture (which all snapdragon runs on the ARMv7 instruction set) with different semiconductor technology. So from the factory they were just improving upon existing designs with new model snapdragons, and not all snap dragons are created equal.

http://en.wikipedia.org/wiki/Snapdragon_%28system_on_chip%29


Basically, from the factory these crystals are rated for a certain frequency, and based on their ability placed into different chips. What i'm assuming apple is doing is using their lower rated CPUs for the 4s.

I wouldn't doubt if apple used batches of chips that didn't pass quality control for the ipad 2.

It does not matter that the A5 is under clocked or over clocked. It beat all phone out there with 800Mhz

lol.. i think they are having trouble remembering that apple DROPPED the mhz.. not raised them.

The fact its only a 800 mhz only makes it all the more impressive considering the scores its getting.

And just as well its not 1Ghz with the unbelievable battery drain...

I would hope that the 4S should be better than the 4. But let’s benchmark it against the Galaxy SII or Motorola Driod Razor.

No point until ICS comes out, GB doesn't utilize the dual core processor fully.

cant wait for the nexus vs droid razr comparisons since they use very similar hardware setups. that will really show any difference between ICS and gingerbread.

Plus i believe they have same processors so it should also tell us how much the 720p screen slows the nexus down. Hopefully not much at all.

Hey my dear, 4s used benchmarks that don't mean anything:

Take a look at the on screen results and you see how very little difference there is between the two. Then ICS and it should be just about neck and neck.

The A5 is a dual core 1ghz chip. Not 800 MHz. But in the iPhone 4s its under locked to 800mhz.phonearena isn't wrong, they just didn't mention the under locking.

you mean under clocked/clocking, there is no such thing as under locking a cpu clock (http://en.wikipedia.org/wiki/Clock_rate)

yes, but now he also can use the correct words, plus maybe it will help him better understand the dynamics behind a CPU.

it doesn't matter that it is underclocked it is not dual core 1ghz it is 800mhz and it won't be 1ghz that's it

The point is it doesn't matter if it's a 1GHz chip, but what it's running at. If it were the other way around and it was a 1GHz chip overclocked to 1.2GHz, you'd be jumping all over him saying that it's a 1.2 not a 1.0.

13. clevername (Posts: 1436; Member since: 11 Jul 2008)


Lol. I wasn't jumping all over him. I'm no rabid fanboy, don't even own any apple products anymore. I just wanted to set facts straight. If it was overclocked to 1.2 I'd have gladly made more of that as well. But yes you are right it matters more what it's at.

iPhone 4S has by far the best phone GPU today - a double POWER VR 543 chip.
But coupled with tiny 3.5 inch screen, it means Jack sh!t.
IPhone is NOT a device you want to play epic graphically intense fps's or rpg's on.

As for the CPU, it's just an average dual core underclocked in the name of battery efficiency.
