-MMX
-Introduce eight 64 bit registers (MM0-MM7) and instructions to work with eight signed/unsigned bytes, four
-signed/unsigned words, two signed/unsigned dwords.
-
-3DNow!
-Add support for single precision floating point operand to MMX. Few operation supported, for example addition,
-subtraction, multiplication.
-
-SSE
-Introduce eight/sixteen 128 bit registers (XMM0-XMM7/15) and instruction to work with four single precision floating
-point operands. Add integer operations on MMX registers too. (The MMX-integer part of SSE is sometimes called MMXEXT,
-and was implemented on a few non-Intel CPUs without xmm registers and the floating point part of SSE.)
-
-SSE2
-Introduces instruction to work with 2 double precision floating point operands, and with packed byte/word/dword/qword
-integers in 128-bit xmm registers.
-
-SSE3
-Add a few varied instructions (mostly floating point), including a special kind of unaligned load (lddqu) that was
-better on Pentium 4, synchronization instruction, horizontal add/sub.
-
-SSSE3
-Again a varied set of instructions, mostly integer. The first shuffle that takes its control operand from a register
-instead of hard-coded (pshufb). More horizontal processing, shuffle, packing/unpacking, mul+add on bytes, and some
-specialized integer add/mul stuff.
-
-SSE4 (SSE4.1, SSE4.2)
-Add a lot of instructions: Filling in a lot of the gaps by providing min and max and other operations for all integer
-data types (especially 32-bit integer had been lacking), where previously integer min was only available for unsigned
-bytes and signed 16-bit. Also scaling, FP rounding, blending, linear algebra operation, text processing, comparisons.
-Also a non temporal load for reading video memory, or copying it back to main memory. (Previously only NT stores were
-available.)
-
-AESNI
-Add support for accelerating AES symmetric encryption/decryption.
-
-AVX Add eight/sixteen 256 bit registers (YMM0-YMM7/15).
-Support all previous floating point datatype. Three operand instructions.
-
-FMA
-Add Fused Multiply Add and correlated instructions.
-
-AVX2
-Add support for integer data types.
-
-AVX512F
-Add eight/thirty-two 512 bit registers (ZMM0-ZMM7/31) and eight 64-bit mask register (k0-k7). Promote most previous
-instruction to 512 bit wide. Optional parts of AVX512 add instruction for exponentials & reciprocals (AVX512ER),
-scatter/gather prefetching (AVX512PF), scatter conflict detection (AVX512CD), compress, expand.
-
-IMCI (Intel Xeon Phi)
-Early development of AVX512 for the first-gen Intel Xeon Phi (Knight's Corner) coprocessor.
