SSE4 (Streaming SIMD Extensions 4) is a SIMD CPU instruction set used in the Intel Core microarchitecture and AMD K10 (K8L).It was announced on September 27, 2006, at the Fall 2006 Intel Developer Forum, with vague details in a white paper; [1] more precise details of 47 instructions became available at the Spring 2007 Intel Developer Forum in Beijing, in the presentation.

SSE floating-point instructions operate on a new independent register set, the XMM registers, and adds a few integer instructions that work on MMX registers. SSE was subsequently expanded by Intel to SSE2, SSE3, SSSE3 and SSE4. Because it supports floating-point math, it had wider applications than MMX and became more popular.
For the first time since the release of Windows 11, version 24H2 introduces modified system requirements: A x86-64-v2 CPU supporting SSE4.2 and POPCNT CPU instructions is now required, otherwise the Windows kernel is unbootable.
SSSE3 was first introduced with Intel processors based on the Core microarchitecture on June 26, 2006 with the "Woodcrest" Xeons.. SSSE3 has been referred to by the codenames Tejas New Instructions (TNI) or Merom New Instructions (MNI) for the first processor designs intended to support it.
The updated SSE/AVX instructions in AVX-512F use the same mnemonics as AVX versions; they can operate on 512-bit ZMM registers, and will also support 128/256 bit XMM/YMM registers (with AVX-512VL) and byte, word, doubleword and quadword integer operands (with AVX-512BW/DQ and VBMI).
The SSE2 also complements the floating-point vector operations of the SSE instruction set by adding support for the double precision data type. Other SSE2 extensions include a set of cache control instructions intended primarily to minimize cache pollution when processing infinite streams of information, and a sophisticated complement of ...
However, most 32-bit applications will work well. 64-bit users are forced to install a virtual machine of a 16- or 32-bit operating system to run 16-bit applications or use one of the alternatives for NTVDM. [41] Mac OS X 10.4 "Tiger" and Mac OS X 10.5 "Leopard" had only a 32-bit kernel, but they can run 64-bit user-mode code on 64-bit processors.
SSE3, Streaming SIMD Extensions 3, also known by its Intel code name Prescott New Instructions (PNI), [1] is the third iteration of the SSE instruction set for the IA-32 (x86) architecture. Intel introduced SSE3 in early 2004 with the Prescott revision of their Pentium 4 CPU. [ 1 ]
