According to Kris Ericson over at PSP World, the as-of-yet to be announced PSP2 may have found the chip company to make its GPU. Recently, a UK-based company, Imagination Technologies Group, signed an agreement with “a major consumer electronics” firm that insiders at EETimes have pegged as being Sony. Imagination Technologies Group is likely designing and building the SGX55x graphics chip for use in the upcoming PSP2. Imagination’s PowerVR MBX chip is already being used in the Apple iPhone and iPod Touch to great effect. “The SGX55x chip promises to be much more powerful than what is currently found in the PSP. At the moment, the PSP uses a proprietary GPU designed by Sony that is very similar to the older graphics processor in the PS2.” The new chip promises to deliver unified shader architecture and OpenGL 2.0 support that should make 3D rendering on the next PSP far superior than what is currently available. Below you’ll find a sample picture of texturing capabilities of current chip models as well as a comparison between the current PSP’s GPU and the SGX530. Note that the SGX55x should be more powerful. But the following specs are used as a way to give you an idea of what to expect.
PSP GPU Specifications: 166 mhz core speed 2 MB VRAM Up to 33 million polygons per second 664 million pixels per second (fill rate) PowerVR SGX530 Specifications: 200 MHz Core Speed 13.5 million polygons per second 1200 million pixels per second (fill rate) DirectX 9 Shader Model 3 support / OpenGL 2.0 128-bit color precision Multi-sampling and anti-aliasing |
