But, as I said, I just presented one way to do it.

I still don't see it. Lets say I have a 1024x768 display and I want to display the color black over the entirety of it. You're saying that all things being equal I need 4x the power to render that same image on a 2048x1536 display? That sounds inefficient to me.

They want devs to create iPad apps and customers to use them. For those reasons I wouldn't expect any change and perhaps eventually the quite removal of iPhone apps on the iPad altogether.

That's a good point. If Apple cared about iPhone apps on the iPad they would a) use the retina-quality images instead of pixel-doubling when in 2x mode and b) rotate the darn thing when in landscape mode. About the only time I use portrait mode on my iPad is when I need to use an iPhone only app. Apple must know this (not my personal experience, just that it iPhone app in an iPad experience rather sucks), but they choose not to address it.

And looking at the state of the Android and iOS app stores for tablets I think one could argue that this decision played a role in creating a lot of quality iPad app. I certainly remember the Android 2.x tablets and people claiming that Android smartphone apps on a tablet was just as good.

Perhaps we'll get this with iOS 5.1?

I can't recall a single iPhone app I had to repurchase because of the double resolution display.

There were plenty that didn't create Universal apps to work on the iPhone/Touch and iPad but there were also plenty that did, free of change.

On top of that, there is no need to "repurchase" your apps or 'waste more money" because they will look just as good on the iPad 3 as they do on the iPad 1/2.

I don't recall ever having to do anything like this.

Some apps that I purchased on the day of the original iPad's release are still providing free updates.

Do ya want me to make a mockup? I'm in discussions with a local famous chef as well as a mental health charity. I honestly hope to publish an interactive Super-HD iBooks2 by Christmas to coincide with iPad 3 Christmas Gift Frenzy.

Played around with iBooks Author already, very naiicee.

Oh what the heck I'll proceed to make a mockup now.

They are kinda fun, and it's a very good proof-of-concept having a game rendered in vectors, with antialiasing, that doesn't peg your fancy CPU 100% like Flash. Of course, I would prefer Mass Effect 3 in SuperHD on my iPad 3, but, ah well, just a few more years. That said, if "hardcore gaming" was all we cared about, we would never have beautiful, non-violent gems like Cut The Rope.

PowerVR specs of future chips indicate that they have the same level of performance as the ps3 at the end of the year using ony a few watts.

The GPU does not need to be 4x the power, or 4x the "VRAM", because of 4x the pixels.

Because by that token, for 2D or 3D games, going from 1024x768 to 1920x1080 on a PC means you need a GPU that is 2.64 times as powerful, with 2.64 times the "VRAM". Which is certainly not the case.

The 4x only directly applies to the final framebuffer, whereby you need 12MB for the output as opposed to 3MB.

Everything else is dependent on the implementation. GPU power and "VRAM" requirements do not scale linearly with pixels pushed.

I have been so utterly looking forward to retina display since iPad 2 that it's not funny.

To hell with the incredible, gorgeous-looking games that this is going to encourage developers to create.

I'm just looking forward to reading a book on the thing!

Thanks for the post. This does get me excited.

Note the text above I bolded. There will plenty that will say magazines and other printed material has more DPI than the iPad and that iPad might be pretty decent but it's not nearly as good as printed material. Please try not to beat them with your iPad 3... I'd hate for you damage a perfectly good iPad.

Note that the screens above are generated natively from the currently-shipping iBooks Author. For several years now, Keynote has supported "SuperHD" resolutions, allowing for some digital projections of these material to be done by seamlessly combining 1080p projectors, such as for the product launch below:



Now imagine most of the Macs above replaced by an iPad 3.

Also, now that digital cinema has evolved significantly, all you would need is an iPad 3 and 4K digital projector (iPad 3 resolution sits somewhere between "2K" and "4" resolutions.

Given the Keynote/iWork software similarity to iBooks Author, Retina Display iBooks are now clearly already available in iBooks Author.

(Note that I never said anything about memory use being 4 times as much.)
And that's ofcourse a worst case scenario.

The point is that you need 4x the rendering speed for the most demanding tasks not for every rendering. But if you don't have the 4x rendering speed your game will drop frame rates (and stutter) at some points in the game, while the game with the 4 times lower resolution runs fine.
So the 4x faster is a worst case requirement and essential to have.

J, Here's what the iPad2 dualcore SGX543 does:



If the iPad3 ~must~ have 4x the performance, they would have to have 8 cores for the iPad3, or use the Rogue GPU which would have to be shown to do 4x the performance of the ~dualcore~ SGX543.

When the iPad3 comes out, if the GPU doesn't have 4x the performance of a dualcore SGX543MP4, that is, as per Wikipedia, 14.4*4 = 57.6 GFlops, I buy you a beer? If not, you buy me a beer?

Remember a GeForce 8500 GT does only 43 GFlops in singlecore. The PS3 is estimated to be around this ballpark, though graphically it is probably not as good as a 8500GT at the 1280x720 resolutions it runs at before upscaling. If the iPad 3 could do 1024x768 graphics at 8500 GT resolutions, with 1080p upscaling to HDTV, then I will be indescribably happy.

OK, final one for now:

If the numbers are correct (and I think they are) logic dictates that that is the case.
It seems a lot of graphics power, but the device would be underpowered if it wasn't that fast.
It could be ofcourse that the GFlops are close to the 57.6 GFlops needed (say 50 or so) that would be acceptable I think.
My estimate was that they had to choose the Rogue version to be able to achieve the performance needed, and this version is available.
It could also be that Apple has made an adaptation of the current version of the GPU with, say 400MHz quad cores.
We will see.

(Nice of you to show the numbers, that definitely improves the discussion.)

The RSX in the PS3 can do either 240 or 400 GFLOPS (Wikipedia says around 400, other people say around 240 GFLOPS). On top of that, the PS3's CPU can do ~150 GFLOPS (6 SPUs available for games).

However the GPU architecture in PowerVR is more efficient due to the tile based renderer, but not enough to make up for the above in raw power.

People are saying it needs 4x to match if they boost the resolution like the rumors all say. Maybe the current GPU exceeds what currently runs. If (random number use here) the system is capable of handling 1280*1024 currently before hitting slowdown, then they would only need to add 2.4x current power, not 4x. That is a big chunk cut off requirements.

I don't know how things go honestly, but it's just an example. If the current iPad 2 already outclasses its current resolution, things don't have to stretch quite as far.

Yeah, I was a bit iffy on the GFlops for the PS3, not sure where exactly I got the low number, the other estimates seem very high but in reality the graphics performance of the PS3 is not that great. So maybe not a good comparison because GFlops is not really directly related to visual performance.

In any case though that's one metric in measuring the PowerVR chips.

I put it as "3K" in quotes because it's sort of inbetween 2K and 3K resolution, plus it's 4:3.

2K video is 2048×1080 and 4K is 4096×2160. Red's "3K" Scarlet has a 3072x1620 or so sensor.

Retina Display on iPad 3 is QXGA [2048x1536], based on the evidence. The only thing is no video is made in QXGA resolution or ratio.

In my mockup above it's cropped and downscaled from a Red 4K sample to QXGA ratio.

Suffice to say if there is ever a chance of iPad 2/3/4/5 Retina Display capable of displaying QXGA video, the best results would be using a 3K or better digital camera or scanned film to have really nice video on iPad Retina. As we know, even 2K video will have to be upscaled on an iPad Retina, let alone BluRays.

Also, as shown above, for digital projections of superHD presentations if the iPad Retina can video mirror QXGA, you would need the 4K digital projector which is what I think digital cinema has standardised on (2K is too low, and there's no common 3K digital cinema projectors).

Very exciting times. The video resolution is simply insane on an iPad Retina. I forsee digital film really taking on the iPad Retina as a portable, simple monitor of sorts if it's ever able to interface with the iPad Retina. Certainly for digital still cameras no doubt the iPad will be essential for mobile viewing of high-res digital stills ~ as some have mentioned.

And if the iPad Retina can play 1080p video, you can see it in native pixels on the iPad Retina. No mean feat on 10".

I imagine as we speak China is churning out portable Blu Ray players with this kind of 10" panel technology.

Not so sure about that, even the latest Infinity Blade on iPad 2 doesn't have a freely moving user-controlled camera, so I think the iPad 2 is mostly maxxed out as it is.

Dear (jn)+,
The assertion made in your posts is that the processing required to support high resolutions is proportional to number of pixels. The evidence provided is that this is would be logical. You may or may not be aware that much of the underlying foundation for *3D* programming involves linear algebra applied to polygons. Matrix transformations can be used to determine position in a 3D space, probably to apply lighting effects, and other effects. As a result, polygons can be a constraining factor and performance specifications for 3D cards are often expressed in terms of number of polygons, more so than "pixel count". If this is wrong and your understanding of implementation and hardware requirements is more detailed, then please add to this discussion. If not, it would be much appreciated if you could refrain from saying "four times more pixels requires four times more power, of course" which may be more of a guess than carefully considered.

I'm not sure if it is an on rails game due to worries about overdoing it against the gpu or if it is b/c they had a hard time coming up w/a good way to have the look around functionality work. Probably some of both, but I don't know
