- PPE has 128 VMX registers now, and a dot product instruction (I think).

6 SPEs are available to applications - as speculated/expected by many, a SPE is reserved by the OS.

For the first time, Sony references the architecture RSX was based on specifically - the NV47. 24 2D texture lookups simultaneously = 24 pixel pipelines. 384 flops/clock.

Two models for RSX programming:

PSGL - high level
libgcm - low level, to the metal

I'll update as I get more out of Google.

the important info is the confirmation that PS3's RSX GPU is based on the NV47 (G70)
