Jaguars have their own FPU. It's a big improvement over bobcat, but not sure if bobcats were sharing fpu resources between cores before. Maybe that's a reference to another architecture.
Well, the vg leaks report mentioned custom hardware for audio, data decompression and video...things which would use SPU jobs on PS3. So that helps.
If there's a further 'compute module' per Eurogamer's suggestion, that too could help, sure. But as they say themselves, I'm not sure what the gain would be over devs just using GPGPU (asides, obviously, from sparing the GPU...). We'll see what that thing actually turns out to be. Maybe it's an amalgamation of the hardware vg leaks mentioned or maybe it is something less fixed function.
But with or without any of this stuff, Orbis would have plenty of fp compute in its GPU if devs want that. It's the best place for it to be since a lot of devs end up just using that on CPU for graphics related tasks anyway...
