iPad Air graphics rated up to 70% faster than iPad 4

Apple claims the A7 chip inside the iPad Air provides two times faster performance over its predecessor, the fourth-generation iPad driven by the A6X chip, in both CPU and GPU department. The claim exasperated disbelief among some watchers who questioned and dismissed Apple’s ‘two times faster’ mantra as pure marketing talk with strings attached.

Per early GeekBench scores, the iPad Air is over 80 percent faster than the iPad 4, close enough to Apple’s advertised 2x CPU gain. But what about graphics?

Putting the device through a barrage of specialized and industry-standard benchmarks, AnandTech’s Anand Lal Shimpi found the iPad Air outperforming its predecessor in terms of graphics by a significant margin.

Specifically, the device is between 40 to 70 percent faster in GPU tests versus the previous generation. Th exact speed gain is dependent on a number of conditions like workload, the type of apps, APIs, software optimizations and lots more.

While only a triangle rate performance came in slightly lower, the iPad Air’s GPU outshone its predecessor  in the 3DMark Ice Storm benchmark (36 percent better), T-Rex HD game simulation benchmarks (a whopping 75 percent better) and 3D Mark (60 percent better).

What’s remarkable is that the A7 achieves this level of performance gains despite having a narrower 64-bit memory bus than the iPad 4’s 128-bit memory interface on the A6X chip.

For those wondering, AnandTech identified the A7’s CPU section as two 1.4GHz 64-bit Apple-designed “Cyclone” processing cores with 128KB L1s (64KB I$ + 64KB D$) per core, a shared 1MB L2 cache and a 4MB L3 cache that services the entire chip.

The GPU is Imagination Technologies’ PowerVR G6430 “Rogue” part, estimated to have a peak clock frequency of 450 Mhz.

Bottom line: the iPad Air leaves all prior iPads in the dust.

It’s a screamer for graphics-heavy apps and games and based on the real-world numbers. If these benchmarks are an indication, Apple’s ‘up to two times faster’ claim does in fact hold up – and that’s a reassuring thought.

I was taken aback learning the iPad Air has the A7 chip.

What I was expecting was a souped up A7 variant – the A7X if you will. That’s what Apple did with the iPhone 4S (A5) / iPad 3 (A5X) and the iPhone 5 (A6) / iPad 4 (A6X). On the other hand, when the original iPad launched in 2010, it ran the A4 chip that a few months later was found inside the iPhone 4 as well.

What does the fact that Apple deployed the A7 across the iPhone 5s, iPad Air and Retina iPad mini mean? For starters, it gives developers a single chip platform to target for all new devices, simplifying development and reducing time to market.

More importantly – and I know this because I yesterday read AnandTech’s ridiculously exhaustive review – Apple very intentionally architected the A7 to support iPhones and iPads. Disregarding a couple tweaks on the iPhone side – such as a narrower thermal footprint, lower-clocked CPU/GPU and other power-related optimizations – your iPhone 5s basically enjoys the same CPU/GPU power as the iPad Air.

Maybe the A7 will pop up next inside an upcoming Apple TV hardware?

It would make a lot of sense.

Instead of tweaking the silicon to produce multiple chip SKUs for the iPhone, iPad, iPod touch and Apple TV devices, Apple can now develop a single piece of silicon and only marginally optimize it in software for its devices, essentially giving each the same lowest common denominator as an app platform.

And given Apple’s volume needs (between 250 and 285 million iOS devices should be shipped in fiscal 2014) and economies of scale, the unified A7-for-all approach really is a no-brainer.

    “I’m still vetting other SoCs, but so far I haven’t come across anyone in the ARM camp that can compete with what Apple has built here. Only Intel is competitive.”

    Best line of the whole review. Everyone else is racing to put quad cores in their phones and here Apple is thinking ahead and looking to the future.

    but where is A7X???

    • Jonathan

      Why would they release it just a couple months after the A7?

    • Maxim∑

      Apple changed the naming scheme. A6 and A6X were the exact same chips but the A6X has a different GPU. This time the GPU’s are the same but iPad air has a higher clock rate so since it’s not different apple just named it A7

      • NSA

        A7 is 90% faster than older models

    • NSA

      No need for it because A7 64 bits has been used in ipad Air, which is really fast. So I don’t think A7X will have a much better in speed than A7. Definitely there will be difference but not huge…

    • mehrab

      The a7 on the ipad air is clocked at higher speeds then the 5s you can even see that it scroed much more then it

    • hkgsulphate

      you know what that x means? probably 0.2 more GHz + heat spreader

      • Salamihawk

        Actually the X meant a better GPU, since the older GPUs couldn’t drive a 2048×1536 display. Now it seems that the A7 has more than enough power to drive the iPad’s display, yet it’s efficient enough to use in the iPhone. Win/win.

    This is really good, advancement in graphics, let’s hope we actually see many developers make use of the extra capability of the A7 before the introduction of the A8..

  • n0ahcruz3

    Ipad 2 & ipad mini = ripoff
    Ipad air & ipad mini retina = worth every penny

    • Osama Muhammed

      I’m still with ipad 2, I’ve never wanted to upgrade.. Long live big boss

  • Svs

    I think x as in a6x and a5x is for quad core graphic and since the a7 already has the quad core graphic the dont need to name it a7x anymore .and this is just a guess :D
