Infinity Blade III (iPhone screenshot 002)

Early Geekbench benchmarks of the iPhone 5s seemingly prove Apple’s claim that the new 64-bit A7 chip provides two times greater CPU and GPU performance over its predecessor, the A6 package inside the iPhone 5. Specifically, the iPhone 5s Geekbench score (the new version of the Geekbench app supports 64-bit chips) is close to the early-2010 Mac mini model.

But how do benchmark scores translate into real-world performance in your favorite apps? Blogger Lex McFarley did an interesting head to head test using the iMovie app running on both an iPhone 5s and a previous-generation iPhone 5. Perhaps unsurprisingly, the new phone rendered the video in half the time as the iPhone 5…

As noted by Macsfuture, the A7 chip has a Geekbench score of 2552, which is “is close to the score of the early-2010 version of the Mac mini”.

Here’s the iMovie test.

The entire project runs ten minutes 55 seconds long.

It took the iPhone 5s about six minutes to render the project in full HD resolution – that’s almost two times faster than real-time rendering, which includes the time needed to copy the resulting movie back to the Camera roll.

Apple says the A7 supports OpenGL ES version 3.0 to deliver the kind of detailed graphics and complex visual effects “once possible only on Mac computers, PCs, and gaming consoles”.

The difference is amazing. Take the imaginary worlds in games, for instance. Textures and shadows look more true to life. Sunlight reflects off the water. The whole experience feels much more realistic.

A more in-depth speed comparison of the two phones follows below.

Created by Tom Rich, the following video not only covers the general speed, but gaming performance of the 64-bit and 32-bit processors and much more.

Apple now has the first 64-bit smartphone on the market running the first 64-bit operating system with all stock apps optimized for 64-bit computing.

It should be noted that while navigating the handset and launching apps appears smoother on the iPhone 5s, these common tasks don’t appear any faster versus the iPhone 5 due to timed UI animations in iOS 7.

Had Apple removed these transitions altogether, the speed increase would have been more noticeable. Of course, the difference in speed become readily apparent when running graphics-intensive apps and high-end games optimized for the A7 and the 64-bit platform, such as Infinity Blade III (pictured top of post).

Here’s Infinity Blade III demo from the keynote.

By all accounts, Apple has likely licensed the ARMv8 architecture for the CPU.

There’s little doubt left that the A7 runs a 100 percent customized CPU core, alongside what’s probably Imagination Technologies’ PowerVR Series 6 GPU code-named Rogue.

Apple holds a ten percent stake in Imagination.

The iPhone 5’s A6 chip was a break from Apple’s previous strategy of incorporating ARM’s CPU blueprints into its A-series chips on an as-is basis.


Instead of using either the ARM Cortex A9 or ARM A15 CPU core for the A6 chip, Apple had licensed the ARM v7 instruction set and produced a fully customized dual-core CPU core named Swift.

As per usual, the industry is expected to close the gap some time next year, giving Apple plenty of lead time to bank on its “the fastest smartphone” claim. Right after the keynote, Samsung co-CEO Kim Yoo-chul said future Samsung phones will have 64-bit processing functionality, although “not in the shortest time”.

  • Hmmm?

    Why do you always quote yourself.. lol? Yes, you have twitter. We know already.

    • f1ght3r

      He wants more followers…

  • omrishtam

    oh god cant wait to switch my iphone 3gs with 5s…….!!!!!

    • Saeed Ghattas

      It’s about time you upgrade lol

      • omrishtam

        believe me i know

  • TesticularFortitude

    Can someone remind me how Apple and the iPhone are doomed again?

    • mehrab

      They are not

    • Tom


    • FOFF

      its a very slow doom

  • ClaudieX X

    Us… Users, programers and tech experts… knows that iphone 5s is “THE” Phone. Apple changed the wheel again!

    • Kurt

      Samsungs Exynos 64 bit chip is in the final stages of development. Pantech Vega LTE-A UX has a fingerprint scanner and it acts as a selection tool also by swiping gestures. If the iphone 5s was 5 inches I would have stayed. It’s a great phone. But Apple didn’t reinvent the wheel. Overall, Note 3 is still better. But again, I would have stayed with iOS if they would have given us a larger screen. Hopefully next year?

      • Taf Khan

        Next year the new iPhone 6 will hopefully deliver a larger screen. The Note the is however too large, I wouldn’t want to be seen with a pan tech, no offence but not for me. As for the Exynos 64, don’t think it will stop the Samsung S5 going plastic, I would want it as much as I want the iPhone 5c, plastic is not appealing.

      • FOFF

        yes i am waiting for the i[hone 6 wit larger screen the 5 was was nice but i always really anted a proper bigger screen

      • Saeed Ghattas

        I think even if the samsung s5 or whatever it will be called, would have a 128bit processor still the iphone with half the ram and dual core (not octacore) would be faster! And we are very proud of the iphone size not a phablet!

        1st… Knowing the news doesn’t solve the problem. Android is Linux based and iOS is Unix based. So being the same kernel estructure the only reason of all the problems of Android to change to 64 bits is because android apps are not Linux native processes, they are Dalvik executables that works on a java like virtual machine, they are more JavaScript code within native JavaScript engine… Exact the same as Google ChromeOS. If you know programming just open a .dex android app and you will see what I’m talking about. So Android going to 64 bits with the ARMv8 (heart of the Cortex A57) will be a mess.

        2nd… Pantech Vega launched a couple of days before iphone 5s… quicker because is the same Pantech but with fingerprints scanner. Not new Os, Not 64 bits, nothing new… and take care… Pantech Vega fingerprints scanner tech READS A CHOMPED FINGER because it reads 3D images of the finger without touching the phone. iPhone 5s sensor is far superior and secure because it have a capacitive sensor that needs a LIVE FINGER to work… so better stay away from the Pantech new phone.

        3th… its OK if you need a bigger phone to feel good psychologically. Anybody that studied Freud knows the reason… Thats why Phablets are best sellers in Asia… its OK buddy… I undertand you…

        4th… if next year a bigger iPhone comes… there will be an iphone for everyone…

  • Dri

    off topic but does anybody else have problem getting google calendar to sync on the stock calendar app after fresh restart on IOS 7?? it work`s on IOS 6

  • Tom

    Shamsung octa cores has nothing to say. 😛

  • House4life

    This makes Samsung feel like shit , they have an octacore phone that can’t even catch up to this beauty

    In the three days that I have had my iPhone 5s, I have to say, I notice a significant increase in the overall feel of the phone. I’ve run iOS 7 on my iPhone 5 before I handed it off to my father, and it does feel much smoother on the 5s. There are still bugs which need to be addressed in iOS 7, and once Apple smooths a lot of those out, the 5s will feel very fluid and smooth itself. And the processor is definitely faster (obviously, you need 64 bit supported apps like Infinity Blade 3 to understand the 64 bit architecture as a feature), just look at burst mode taking 10 photos per second, that’s sheer raw performance coming from the A7 chip. And let’s not forget the slo-mo video which is quite the novelty feature that may come off as gimmicky to most, but still a cool feature for photographers/film makers. I thought the 5’s camera was great, but the 5s’ camera is fantastic, even with the low-light photos I’ve taken. And I have to say, the overall feel is really nice, especially the home button… although it’s new and less worn in, it still feels like it can hold up against the test of time. I really love the space gray color and have downloaded some space wallpapers in honor of the name.

    both render to damn

    Hi, I always noticed colored iphone 5 in videos. so I want to ask if someone can give me a website for such a service.
