x86 architecture
3 byte opcodes




note: A leading bold V indicates that the instruction can be VEX-encoded, in which case it may have additional operands.
note: A leading bold ! indicates that the 256-bit version was only introduced with AVX2 and that it can only be VEX-encoded.

note: AVX10.1 is comprised of AVX512{F,CD,BW,DQ,VL,IFMA,VBMI,VNNI,BF16,VBMI2,BITALG,VPOPCNTDQ,FP16} and
of the EVEX-encoded variants of VAES, GFNI, and VPCLMUL, but not AVX512{PF,ER,QFMA,QVNNIW,VP2INTERSECT}.
AVX512QVNNI didn't ship in KNM as originally planned. AVX512DFMA and AVX512BITALG2 were specified but didn't ship.

note: AVX10.2 is comprised of {BF16,COMX,CVTFP8,DP,SAD,MINMAX,CVTS,VMOV} and 256-bit {er} and {sae} variants.
note: A leading bold !! indicates that the 256-bit {er} or {sae} variant, encoded with U=0, was only introduced with AVX10.2.
note: Although SM4-EVEX, VMOVRS* from MOVRS, and AMX-AVX512 depend on AVX10.2, they are not part of AVX10.2.

notes descriptions
#1 The use of Rb=AH/CH/DH/BH results in SPL/BPL/SIL/DIL. Without a REX.40 prefix, in case of the SSE version.
#2 The zero match codes are TD, TD (alias), MO, and MZ. They are encoded as the zzzz field of the Ib, using 0...3h.
#3 The condition codes are EQ/LT/LE and NEQ/NLT/NLE. They are encoded as the Ib, using 00h...02h and 04h...06h.
#4 The condition codes are EQ/LT/LE/FALSE and NEQ/NLT/NLE/TRUE. They are encoded as the Ib, using 00h...07h.
#5 The condition codes are EQ, LT, LE, UNORD, NEQ, NLT, NLE, and ORD. They are encoded as the Ib, using 00...07h.
With EVEX, there also are: EQ_UQ, NGE, NGT, FALSE, NEQ_OQ, GE, GT, TRUE (08...0Fh),
EQ_OS, LT_OQ, LE_OQ, UNORD_S, NEQ_US, NLT_UQ, NLE_UQ, ORD_S (10h...17h), and
EQ_US, NGE_UQ, NGT_UQ, FALSE_OS, NEQ_OS, GE_OQ, GT_OQ, TRUE_US (18...1Fh).
