Architecturally Power7 has 64 unified VSX Registers for floating point and vector processing versus 16 for SSEx. It also has 2x thread count per core than newest Intels, so in total number of architectural registers usable for FP Power7 wins 8x per core.

But it's likely contemporary scores can't utilize this fully yet.

VSX

Power ISA v2.06 introduces the new VSX vector-scalar instructions which extend SIMD processing for the Power ISA to support up to 64 registers, with support for regular floating point, decimal floating point and vector execution. POWER7 is the first Power Architecture processor to implement Power ISA v2.06.
