Well, I originally wanted to post something new, but everything has been said, so I'd just summarize
The P10 isn't a CPU but a "VPU" as the guys over at 3DLabs would have it, or "Visual Processing Unit". Its a highly programmable graphics processor, much more so than nvidia's Vertex/Pixel Shaders, making it more general purpose.
Creative has just acquired 3DLabs, and hence while its technically correct to say that they're making the chip, its actually 3DLabs's engineers who designed it and they probably have TMSC or some other fab manufacture it. Creative is just the name behind it all.
Specs are pretty impressive and promising, but initial reviews put it behind the nvidia Quadro4 XGL750 and XGL950 in most professional benchmarks.
