The Cell SPE has 128 registers of 128 bits.

"Synergistic Processor Elements (SPEs) The eight SPEs are SIMD
processors optimized for data-rich operations allocated to them by the
PPE. Each of these identical elements contains a RISC core, 256-KB,
software-controlled local store for instructions and data, and a large
(128-bit, 128-entry) unified register file."
Yours,
