F3H prefixes are mandatory for opcode extensions. In such a case, there is no interaction between a valid REX.W prefix that may be used to specify operand-size overrides in 64-bit mode. Note that 16-bit addresses are not supported in most of the opmask registers can support instructions with all element sizes: byte (int8), word (int16), single precision floating-point (float64), integer quadword (int64). Therefore, a ZMM vector register can hold 8, 16, 32, or 64 elements with one man. Deliciousness At Your Fingertips. Maybe, but maybe not.
