PS2 had Vector Units: VU0 and VU1
VU0 2.44 GFLOPS
VU1 3.08 GFLOPS (with Internal 0.64 GFLOPS EFU)
PS3 had the SPE's 
" In 2000, IBM, Toshiba and Sony collaborated to create the Cell processor, consisting of one scalar processor and eight vector processors, which found use in the Sony PlayStation 3 among other applications."
that was 25.6 GFLOPS each 6 = 153.6 GFLOPS of vector processing from the SPEs (not counting the 7th SPE that was used for the OS)
PS4 = ???   only the Jaguar Cores  & GPGPU Compute?  maybe but this just doesn't fit with all the other PlayStation Home Consoles  so I'm holding out hope that their is a Vector Co-Processor in the PS4.
