I don't agree, the Broadcom GPU may be fast when it comes to actual rendering, but it is a LOT less capable than any PowerVR SGX core because of memory issues.

On Symbian^3 devices the broadcom chip only has 32 MB video memory, and because of the hardware accelerated GUI of Symbian^3 some 10 MB is permanently in use, leaving only 22MB for actual textures that can be used inside games.

A PowerVR SGX core has shared memory with the RAM, and is MUCH better suited to play games. The Broadcom was chosen as a cheap solution to make a relatively underpowered phone do video and image processing well. It was never chosen for its gaming/OpenGL capabilities, and that is the whole point of the PowerVR core. For video acceleration maemo uses a different DSP core on the Omap3, that is not PowerVR related.

I would prefer the PowerVR core in the N900 to the Broadcom chip used in Symbian^3 devices.
