I type on the iPhone all the time, too! That didn't give me any excuse to use bad grammar. It definitely didn't give me any excuse to be ignorant, either.

I openly admit to being ignorant of a few things.
You do not. The word for that is pompous ;)

And BTW I'm typing on my iPhone while riding on a unicycle stoned out of my mind.

Excuse my grammar.

Mr. Touchy
 
Since the display will be using more power than the previous gen, I'd expect a modest yet substantial upgrade. As in more graphics processing, scaleable power draw, and a slightly higher clock. No use running more cores when the A5 @ 1GHz does fairly impressive work, and multitasking is still not very heavy given the OS design. Ram- yes, 1GB would help, as would a better architecture to access storage. But the A6 has to wait until the display uses less power and the battery gets an internal bump.
 
What's in a name? In the case of the A5X who knows. But ARM does make a quad-core A9. So it's not out of the realm of possibility that Apple is sticking w/ the ARM A9 & just going QC. Then save the Apple A6 for the next iPhone.
 
With the timeframe at which the iPad 3 will be released, we already knew it couldn't have a Cortex A15 quad-core processor, which will be released at the end of the year.

The choices were:

Dual-core Cortex A9 (like in the iPad 2)
Quad-core Cortex A9 (like in the PSVita)
Dual-core Cortex A15 (like the newly announced Samsung Exynos 5250, TI OMAP 5)

Given the poorer efficiency of quad-core processors in general and the better efficiency of the A15 architecture over the A9, a dual-core Cortex A15 would have performed better than a quad-core A9 that's clocked slower.

Apple usually cares more about real-world performance than about having impressive spec terms anyway. Those that would like to brag about having a quad-core phone are generally more interested in Android-based phones to begin with.

I think it's safe to assume that the A5X will not be a quad-core. The number of cores was the only "spec" Apple has talked about when they presented the A5. Now that the new A5X SoC doesn't have more cores, it's hard for them to justify an A6 being significantly better than the A5 without getting technical and explaining the architecture difference between a Cortex A9 and A12, which Apple obviously wouldn't do. A5X makes it sound like it's the same old dual-core processor, just faster (like iPhone 4S vs iPhone 4).

Now there are two possibilities:

  1. The A5X is still just an A5. It uses the same Cortex A9 architecture but it is now clocked higher. That would be weird since the iPhone 4S also uses an A5 with a different (slower) clock speed, yet they didn't rename the SoC just because of this. The "X" would basically just be a marketing term to make people feel like the CPU is new, while it's not really. All they would need is a bigger battery to compensate and good heat management, which shouldn't be a problem.

  2. The A5X is a new dual-core SoC based on the Cortex A15 architecture. It's about 50% more powerful and efficient than the A5. This would be even better than having a quad-core Cortex A9 (the only possible quad-core SoC right now) and the absolute best we could hope the iPad 3 to have. The iPhone 5 could have a new A5X as well and benefit from more power/efficiency without having a higher clock, which is desirable for a device as small as the iPhone.

tl;dr: Either the iPad 3 will just have a higher-clocked A5 and the "X" is just a marketing gimmick, or it will have a new dual-core Cortex A15 CPU which is actually more powerful and efficient (50% faster at same clock speed). No quad-core and that's a good thing.

Agreed. I reckon that this is what'll happen, i.e. dual A15, which is a great thing IMO. Also interesting to note, but first thing I thought when I saw was:
A5X = 5 + X >>> from roman numerals ala Mac OS X...
= 5 +(10)
thus A5X = A15.

More interesting I think is what graphics they're going to use. Are we going to see the 543MP4 quad core varient in this? Apple have put a large priority on graphical capabilities of there iOS devices, surprising regarding the comparisons in their other products (although last years iMacs and MBP's are hopefully an indication of more focus here). iPad and iPhone typically have graphics hardware that is class leading - who'd have thought?

This thing will likely approach graphical capability of the PSVita. Given the resolution of the display this is a great thing, imagine 2D games on that screen.
 
The two things I'd want are

(a) Retina
(b) 1g Ram

I was hesitant to buy the first iPad because the screen was terrible compared to my iPhone 4, but I decided to take the plunge, and having done so, I am very annoyed by the constant crashing of the first iPad, due to a lack of Ram, which has only become more common with the new iOS updates. I'm ready to upgrade to the new iPad only if there is enough ram to convince me it won't run into similar problems within 2 years of purchase.

Why wouldn't they include 1 gig of RAM ?

RAM is so freaking cheap as it is.

Let's hope for the best guys! you know Apple an be cruel at times, but hopefully they do know more RAM should be an obvious upgrade.

Quad-Core Cortex A9. Mark my words. Reasons:

-Apple's AX designations symbolize architecture jumps rather than more cores. So A5X would mean same A9 architecture but X probably meaning quad core variant.

-The recently leaked boot diagnostics screenshot showing 4 cores.

-Quad core support discovered in iOS recently.

-Dual core A15 would outperform quad A9. If they were going dual A15 in the iPad 3, that'd more then justify it being an A6, which as we see here, it isn't.

-It would allow the fourth iPad to bear the name 'A6', Apple always save something good for later. A6 being a Quad core cortex A15, the best of both worlds, (later when they're more available).

-Apple are said to be getting apps together that really show off the iPad 3. Apart from spectacular Infinity Blade 2 graphics which we've seen before, what else can they demo? Possible answer: apps that take advantage of quad core.


That's my theory. Whatever the case, this'll be my first iPad, been waiting long enough. You have to jump into the ever-moving 'spec river' sometime. Yea, it'll be annoying seeing the iPad 4 go Quad A15 probably, but what the hell. :p
 
I also hope it will kick the transformer prime's butt game-wise.
I watched some videos comparing it to the ipad2 and come on...the freeking prime lags sometimes in normal operations...unaccepatable. But the games that were installed were wow... I hope riptide gp will be updated for the ipad3. Then its retina screen with that game will slaughter the prime(i hope).
I guess apple knows what gpu and cpu they have chosen:) and chose them for reason.
 
iPad 2S,2X, or 3

One thing to think about is Apple's A4 used the Cortex A8, & the A5 used the Cortex A9. Going to a Cortex A15 CPU would mean Apple would have to brand their processor the A6 because it denotes a new architecture. For that reason, I don't see the A5X being based on Cortex A15.

I see the following two options;

The A5X still uses the dual-core Cortex A9 CPU, but faster clocked. The GPU still remains dual-core but uses the new PowerVR Rogue GPU architecture. That GPU alone, at the same clock speed, would be at least 5X faster than the 543MP2 GPU in the A5 processor.

In option 2, we could still see a quad-core CPU / GPU based on the Cortex A9 & SGX543MP4. Even though it's quad-core it's still using the same architecture as the Apple A5.

iPad 2S/2X/3: 32 nm Samsung A9-dual core at 1.4 GHz; 1GRAM; SGX545MP
(Ref:iPad 2 45 nm Samsung A9-dual core 1GHz; 512MRAM; SGX543MP)
Result: 30-40 % Perf increase; 25% less power/standby 30% less; more RAM for filling display fast enough.
Display and cameras significantly better
A15 not ready till next year; quad A9 too much electrical power, cost, need

Pretty much my thoughts when seeing the A5X designation. Simple and logical.

I was also thinking that using the quad core would be more power efficient which would help with the rumored LTE chip.

Well said. Definitely a very logical theory

So you're basically agreeing with me. Because in my post I mentioned, if not clearly,that the iPad won't get the Cortex A15 architecture this year - hence the A5X moniker, which is a tweak of the current Apple A5 processor.

Again, for the A5X, I see two possible options;

1. faster dual-core Cortex A9 CPU, along with a much beefier dual-core GPU using the PowerVR Rogue GPU architecture

or

2. quad-core CPU / GPU based on the current Cortex A9 CPU / SGX 543MP4 GPU
 
Quad-Core Cortex A9. Mark my words. Reasons:

How would you know?

We've only had 2 iPads so far and both had a different architecture and different number of cores, so we don't know what AX designations stand for.

To above post:

Yea I suppose you could argue it means more cores too. A4: single core A8. A5: dual core A9. A5X: the 5 obviously meaning that some aspect will remain the same as the A5, probably architecture. Like I said if A5X was a dual A15, that's basically good enough to call the A6.
 
One thing is for sure, its not going to be a Cortex A15 based chip as those won't see the light of day till late 2012/early 2013.

Unless the number doesn't represent the actual performance but what is considered better by the public. For most people, quad-core is necessarily better than dual-core.

Either way, it's hard to come to conclusions just with the "A5X" term, we'll find out soon enough what that really means anyway. :p
 
"If its not a quad core A6 then I wont buy it" complaints commence in 3... 2... 1...

Yep, funnier than watching monkeys play at the zoo. Apple products always fail the "spec police" test. The basement nerds only care about cores and such. They always declare the latest gizmo from Apple as EPIC FAIL. The gizmo sells like crazy and the saga continues. :p
 
Sooo a faster dualcore then.
*preorders cancelled :D

;)

Doesn't work like that in the Apple universe. Apple customers are interested in more important things and always have been. The spec nerds can take a hike. They are irrelevant.
 
Well, as long as it can power games on the new screen at a decent frame rate, I'm not fussy.
