Apple iPad Air 2 to have the fast A8X processor under the hood

Apple iPad Air 2 to have the fast A8X processor under the hood
Apple has confirmed that the SoC powering the super-thin iPad Air 2 is going to be the rumored A8X chip. It's still a 64-bit architecture and it is the home of 3 billion transistors that do the calculations under the hood. Apple claims that the graphic performance of the new iPad Air 2 will be 2 and 1/2 times faster than last year's iPad Air. And, of course, it supports Apple's Metal API that was first talked about at the iPhone 6 event and is said to enable "console-level graphics" on Cupertino's latest mobile devices.

The A8X also handles an Apple-designed image signal processor, which enhances the capabilities and fluidity of editing pictures. The main processor also got an updated buddy - the M8 co-processor. Much like last year's M7, the M8 is there to track motion, location, and elevation, leaving the A8X free to work on the more serious stuff.

Even with the super-thin profile and performance boost, Apple claims that the iPad Air 2 will still allow up to 10 hours of on time.

Is Apple shy to reveal their processor speed and RAM..?

probably close to 1.9ghz and 2gb

The maths tell me 1.8 GHz.

most probably better than the denver tegra k1

How do you figure this? Do you know something we don't know?

Easilly. You got 1,4x and 2,5 x the performance compared to A7. That means it's at least just as fast as the tegra k1.

That means powerVR GX6650 on board. With ray tracing, that thing is a beast and faster than tegra k1 by a hair. The only mobile GPU that can beat GX6650 is the mali T760MP16. The note 4 rocks the MP6 variant and still matches the A8's GX6450 and adreno 420. Just imagine what MP16 can do.

I think Apple's Metal API and the 20 nm processl will allow the A8 to perform slightly better than the K1 Also the 64-bit K1 seems like a decent improvement over the 32-bit K1 Mainly in single core CPU speed, its single core geekbench is on par with the multicore of the S600http://browser.primatelabs.com/geekbench3/1014854

It's not. Apple claims the GPU in the A8X is 2.5x faster than the A7, NVidia claims the K1 is 3x faster than the A7.

The problem is, nvidia is lying, Apple is not.

You can't say Apple isn't lying because there haven't been any benchmarks yet. Nvidia did give a high estimate, but in many benchmarks the K1 manages to get about 2.5x the performance of the A7. Assuming Apple is giving a high estimate as well, which they probably are, the K1 will still come out on top by a fair margin.

Why would you even say that, don't you think that they didn't show benchmarks because it's NOT better than the competition ? Think about it...

20. Iodine

Posts: 1480; Member since: Jun 19, 2014

nVidia shows the benchmarks, and as you can see they aren't better than the competition... Why ? They always compare to last year's best chip. Apple does the same but only comparing their own chips, they don't need to shout out for 9 months and then get muffled by competition like nvidia does, you have it clear 2,5x faster GPU compared to A7. And that was beast by itself.

on the gpu side tegra is stronger in terms of raw power, but when you see games like gta, they run so much better on apple devices

Umm No. I have no clue what you are talking about.

Of course you have a clue about what he's talking about. It's called fanboyism

A couple more words, Android Run Time (ART)+Android Expansion Pack (AEP), both coming with Android L, plus the now 64 bit OS. I still don't get your point.

Please let me know when you get Android L in your latest 2014 phone... NEVER but getting metal on your 2014 iPhone, instantly

If what Apple claims is true (and they have never lied about CPU and GPU performance) the race for the "SoC of the year" is going to be really close between A8X and Tegra K1 Denver. I would put my bets on the A8X, but that it will win by a paper thin margin and just because of the 20nm vs 28nm manufacturing.

16. Alcahas

Posts: 28; Member since: Jul 24, 2014

True, but we still haven't witnessed a proper head to head battle. I believe the differences on the GPU side will be minute. Also, A8X will be SoC of the year for iOS and The Denver K1 the best SoC for Android, but that's just a thought

19. TylerGrunter

I think that is pretty much a given, the questions are which one will take the performance and the performance/watt crowns.

23. Alcahas

Posts: 28; Member since: Jul 24, 2014

The A8x gpu for sure, as to my knowlege, Nvidia hasn't yet solved the power usage problem, for mobile at least. The Desktop (maybe even mobile) Maxwell is a HUGE improvement in terms of performance/watt

17. Iodine

Posts: 1480; Member since: Jun 19, 2014

I would bet on a lot lower power compustion for A8X. Not because it's a ultra low power mobile chip like A8, but because Tegra K1 is just an power hog... I will take the more efficient chip, not the fastest.

18. TylerGrunter

Posts: 1544; Member since: Feb 16, 2012

At the same performance they have similar consumptions. That Tegra K1 is a power hog was just random sillyness from Charlie (semiaccurate.com) I think the A8 will have a bit lower power comsumption, but not that much, thanks to the half node difference in construction.

28 to 20 nm is a full node shrink. And according to GFX Bench iPhone 6 "known" (by haters) for it's "bad" battery life lasts longer than an nVidia shield tablet which got a far bigger battery, running at over 60% of K1 performance. And A8 is roughly 60% faster than A8.

Nvida Tablet has a bigger screen and we are not talking about two chips with similar performance. The A8 is moving a lot less pixels ina a smaller screen at lower FPS. So it´s not possible to compare. I´m not saying the A8X will be worse, just saying that I prefer to wait for real numbers. The rest (what you are doing now) it´s just speculation... And you are right, it´s a full node shrink.
