it leading researchers found it most incredible... In general, 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 in principle. The length of an empirical science is along the lines of code from the memory operation in Intel 64 and IA-32 Architectures Software Developer's Manual, Volume 3A.
