SSE
In February 1999, Intel released the Pentium III CPU, which includes an MMX upgrade known as Streaming SIMD Extensions (SSE). They were initially featured on the Katmai processor, which was the code name for the Pentium III, and were called Katmai New Instructions (KNI) until its introduction. There are 70 new instructions in the Streaming SIMD Extensions, including SIMD floating-point, extra SIMD integer, and cache ability control instructions. Advanced imaging, 3D video, streaming audio and video (DVD playback), and speech-recognition applications are just a few of the technologies that benefit from the Streaming SIMD Extensions. The SSEx instructions are very beneficial when decoding MPEG2 video discs, which is the industry standard.
SSE has several advantages over conventional MMX, one of which is that it allows single-precision floating-point SIMD operations, which have been an obstacle in 3D graphics processing. SIMD, like ordinary MMX, allows for the execution of several operations per CPU instruction. SSE, in particular, may do up to four floating-point operations per cycle, allowing a single instruction to work on four bits of data at the same time. There are no performance consequences when SSE floating-point instructions are combined with MMX instructions. Data prefetching, which is a means for reading data into the cache before it is needed, is also supported by SSE.
SSE2, which debuted in November 2000 alongside the Pentium 4 chip, adds 144 SIMD instructions to the processor. All previous MMX and SSE instructions are included in SSE2.
SSE3, which was released in February 2004 alongside the Pentium 4 Prescott chip, introduces 13 additional SIMD instructions to improve complicated math, graphics, video encoding, and thread synchronization. All prior MMX, SSE, and SSE2 instructions are included in SSE3.
The SSSE3 (Supplemental SSE3) instruction set was introduced in the Xeon 5100 series server CPUs in June 2006, and in the Core 2 processors in July 2006. SSSE3 enhances SSE3 by adding 32 additional SIMD instructions.
SSE4 (also known as Intel's HD Boost) was first introduced in January 2008 inversions of Intel Core 2 CPUs (SSE4.1) and was later upgraded in November 2008 in Core i7 processors (SSE4.2). SSE4 has a total of 54 instructions, with SSE4.1 having a subset of 47 instructions and SSE4.2 having all 54 instructions.
