to add to AVX-512. This has led them to define a new prefix called EVEX. Compared to VEX, EVEX adds the following benefits: Expanded register encoding...

shipped in 2013. AVX-512 expands AVX to 512-bit support using a new EVEX prefix encoding proposed by Intel in July 2013 and first supported by Intel...

with the EVEX prefix, but none of the instructions in those maps are VEX-encodable. The VEX2 prefix is a 2-byte variant of the VEX3 prefix, that differs...

in the ModR/M byte of an AVX-512 or AVX10 instruction encoded with an EVEX prefix, the displacement encoded in the instruction's disp8 byte will be scaled...

instructions are encoded with the VEX or EVEX prefixes – on the form VEX.66.0F38 xy /r or EVEX.66.0F38 xy /r. The VEX.W/EVEX.W bit selects floating-point format...

2-byte REX2 prefix, while new instructions and extended operands for existing AVX/AVX2/AVX-512 instructions are encoded with extended EVEX prefix which has...
