AVX Extension of the SSE instruction set supporting 128- and 256-bit vector (packed) operands. See Streaming SIMD Extensions. AVX2 Extension of the AVX instruction subset that adds more support for 256-bit vector (mostly packed integer) operands and a few new SIMD instructions. See Streaming SIMD Extensions.

The SSE instruction set includes instructions originally introduced as the Streaming SIMD Extensions (Herein referred to as SSE1), and instructions added in subsequent extensions (SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, SSE4A, AES, AVX, AVX2, CLMUL, FMA4, FMA, and XOP). Collectively the SSE1, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, and SSE4A subsets are referred to as the legacy SSE instructions. All legacy SSE instructions support 128-bit vector operands. The extended SSE instructions include the AES, AVX, AVX2, CLMUL, FMA4, FMA, and XOP subsets. All extended SSE instructions provide support for 128-bit vector operands and most also support 256-bit operands. Legacy SSE instructions support the specification of two vector operands, the AVX and AVX2 subsets support three, and AMD’s FMA4 and XOP instruction sets support the specification of four 128-bit or 256-bit vector operands. Each AVX instruction mirrors one of the legacy SSE instructions but presents different exception behavior. Most AVX instructions that operate on vector floating-point data types provide support for 256-bit vector widths. AVX2 adds support for 256-bit widths to most vector integer AVX instructions. AVX, AVX2, FMA4, FMA, and XOP support the specification of a distinct destination register. This is called a non-destructive operation because none of the source operands is overwritten as a result of the execution of the instruction. The assembler mnemonic for each AVX and AVX2 instruction is distinguished from the corresponding legacy form by prepending the letter V . In the discussion below, mnemonics for instructions which have both and a legacy SSE and an AVX form will be written (V)mnemonic (for example, (
