W: If set, the operation is performed on 64-bit operands. R: Extends the REG field to 4 bits. X: Extends the INDEX field of the SIB byte (if present) to 4 bits. B: Extends the R/M field (or the SIB byte's BASE if MOD≠11 R/M=100) to 4 bits. There is one additional effect of a REX prefix: a REX prefix changes how byte registers are addressed.
