The Cell SPE has 128 registers of 128 bits.$file/CBE_Tutorial_v2.1_1March2007.pdf

"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."
