Ken Kutaragi is really getting around these days. He’s talking to a lot of people but only revealing new stuff a little bit at a time. In an interview with Impress PC Watch he talks of the GPU.

The Cell’s seven Synergistic Processor Elements (SPE) can be used for graphics. In fact, some of the demos at E3 were running without a graphics processor, with all the renderings done with just the Cell. However, that kind of usage is a real waste. There are a lot of other things that should be done with the Cell. One of our ideas was to equip two Cell chips and to use one as a GPU, but we concluded that there were differences between the Cell to be used as a computer chip and as a shader, since a shader should be graphics-specific.
