iOS 4.3 Beta Hints at OpenCL-Capable SGX543 GPU in Future Devices

RE: iPad
iPad 2 will have a higher display. Maybe not that of the iPhone 4, but they will definitely push closer to higher HD.

Samsung actually presented a 400 ppi screen in 2006 (640x480, 2").
Peak numbers tell very little about real world performance, though.
Are you talking about desktop GPUs? A single core SGX543 should be ahead of Tegra 2 for realistic use cases.
Apple has no reason to partner with samsung for the fab of the A5. There are probably many good reason not to if samsung are agressively pushing their product in to the same market. So apple could move to someone who can offer 32nm. Between fabless teams and licensing agreements they have all the IP covered.
Based on what information?
No one is doing 32nm but intel right now, and they offer fab services to very few outside companies, and only smaller ones.
OpenCL support is the most interesting aspect of this news not only for its relevance for iPods, iPads, and iPhones, but because with Apple showing interest in features common to both iOS and OS X, this appears to show Apple's long-term commitment to OpenCL. I wonder what Apple's commitment to OpenCL will mean for its graphics selection in the next laptop revision(s), especially in light of the limited support for OpenCL by Intel?
It would be nice if AMD would bring out a technology similar to NVidia's Optimus (I think something is slated for the near future) so Mac users could have the best of both worlds--smart graphics switching and strong OpenCL support.

Why?
Frankly if they don't have dual core in IPad 2 they ought to have Steveo tested for senility. It would be an incredible screw up not to address iPads performance issues.

Not really, at least not with todays GPUs nor those coming in the near future. It's pretty simple GPS aren't optimized to run serial code. To gain from a GPU you need a code that can exploit a GPUs highly parallel nature.

Why not 1440x1080? Sure there would be upscaling issues but those would be minor issue as developers would just update their apps for the native res. And apple could still call it a retina display because you would hold it at a distance of 18"-22".
According to the Engadget article a couple of hours ago, the new "A5" in the upcoming iPhone 5 is exactly that...a Cortex A9 based multi-core chip.

Quote from that article:
I know, not exactly 1.5x... but it doesn't have to be 2x.
1440x1080??? Sounds like a good res to me!

Interesting report! I especially like the part about an SD slot.
In any event I will restate my previously related position. Apple has mo choice but to move to at least dual core Cortex A9 in iPad2. To not too would be a major screw up that would out strip every Apple screw up to date.

Frankly, I fail to see how harnessing GPU power for consumer-oriented, general computing (not games, not scientific apps) would be of any use in today's app landscape. Please enlighten me!
You're laughing that complex linear algebra whether it's basic linear programming to advanced PDEs are somehow just going to be done for you? All the geometry and tessellations within the Shading Language doesn't solve your Finite Element Design problems.
Just like Sandy Bridge.
apple won't force developers to fix their apps for a new resolution ipad, 1440x1080 will not be done
Cause they didn't make them do it for iPhone 4? Lol.
They aren't forced to anyways, upscaling can take care of the lazy devs.
Microsoft would probably use Tegra technology over this relatively weak platform.

Actually doubling the vertical and horizontal resolution wouldn't "double" the resolution, it would improve the resolution by 4x.

I thank God everyday that you're a brilliant engineer who is well versed in displays, graphics processors, SoC's, and overall OS design. Otherwise, how would I know how awful Apple is at everything?
