Apple Confirms: iPad Uses PowerVR SGX Graphics Hardware

While this shouldn't be much of a surprise to most, Apple has confirmed that the iPad uses the same family of graphics chip as the iPhone and iPod Touch. According to reports, Apple's latest iPad SDK Beta 3 documentation confirms this, though falls of short of detailing exactly which chip it is:

Using OpenGL ES on iPad is identical to using OpenGL ES on other iPhone OS devices. An iPad is a PowerVR SGX device and supports the same basic capabilities as other SGX devices. However, because the processor, memory architecture, and screen dimensions are different for iPad, you should always test your code on an iPad device before shipping to ensure performance meets your requirements.

There was some confusion about the actual hardware that Apple had used due to an erroneous report by Bright Side of the News which claimed that Apple used a far less powerful ARM-based GPU.

Apple is a licensee and major investor in Imagination Technologies who creates the PowerVR SGX chips and has used them throughout the iPhone and iPod Touch designs. Apple's new A4 chip from Apple incorporates both the ARM processor as well as the PowerVR SGX GPU in a single chip.

The MaxiPad with wings... now more powerful. :D

I guess it's not an oversized iPod Touch after all.

I don't know enough about hardware to say whether this is a good or bad thing, but I like my iPhone, so... :o

It's a good thing. Something that very few other companies will be able to compete with.

but given the hardware size of iPad, cant you put more powerful chip than iPhone's. something like laptop style

Do PowerVR still use tile based rendering? I've always had a soft spot for their tech during the Kyro PC graphics cards and Dreamcast era.

Nope. Impossible with the current technology. If they were to put in a graphics card that's strong enough to compete directly with laptops, 1) it would make the iPad very thick and warm and 2) it would be very heavy. All these reasons are what make the iPad what it is - portable, thin and light.

PowerVR SGX is a family (architecture) of GPU's. It's not unreasonable to think the iPad might use a more powerful version (faster clock, more cores, etc.) than the iPhone/iPod Touch version. The fastest SGX GPU's aren't going to be as powerful as the best laptop parts, but given the size and power constraints of the device, they can be quite powerful.

I'm desperate for some more details on this, the graphics processor and the A4 chip in general- so much still unanswered- just what is the chip capable of? Are we talking netbook speeds or better? I know the iPhone OS is fairly light on demands befitting a small battery powered device. Which developers will be the first to really produce software that maximises the A4 potential?

It seems to me that this device, like the iPhone will really be a grower.

Yep. Tile-based deferred rendering, all the way. And, as of the SGX, now with OpenGL ES 2.0 (ie, fragment and vertex shaders through a high-level language).
