A4 Specs

Wikipedia now has a page on the Apple A4 SOC (system on a chip) with some specifics. It appears that it's a ARM-A9 multi-core chip combined with a PowerVR VXD. The article seems to suggest that OpenGL ES 3.x and OpenCL are both possibilities with this chipset.

No matter how you slice it, it's pretty fast for a mobile device and this bodes well for the next generation of iPhones if they can scale the A4 to the iPhone.

It is based on this article:

The Cortex 9 part seems very likely but the Mail-50 GPU doesn't make sense at all.
Unless they simply mixed up their numbers, Mali-55 is GLES 1.x only GPU about as fast as the original MBX ( iPhone 3G)

The article it is based on is all based on guesses and just plain wrong information. In an update, the article even admits "We were told that the ARM licensed its CPU and GPU technology to Apple. That's it." Everything else is just guesses based on that fact. And I wouldn't trust their guesses, based on mistaken facts they list, such as the nVidia Tegra and Qualcomm Snapdragon using the Cortex A9 (those use the A8)
