@XOJ many of the developers on Beyond3d have a different interpretation on the resources available on the PS3. Its not just the GPU + PPU because the PS3 could never hope to compete in multiplatform games with the Xbox 360 by utilizing one core and a weaker GPU.
To paraphrase: "Its a few SPUs for comparable CPU performance, its a few SPUs to help the GPU for comparable graphics performance after that there isn't much left"
Tease.
