SSE3?

[Demo24]

What in the world is SSE3? Or for that matter what in the world are the 2 that come before it? What do they do and why are they important?

thanks!

Here is a piece of intels def

Overview
Single Instruction Multiple Data (SIMD) has industry-wide acceptance as a technology that increase performance on a wide variety of applications. Intel® Streaming SIMD Extensions (SSE) are sets of instructions that Intel introduced with the Intel® Pentium® III processor. This technology was the first major expansion of the Intel® instruction set since the introduction of Intel® MMX? technology in 1995. With the launch of the Intel® Pentium® 4 platform, SSE was supplemented by SSE2. SSE/SSE2 can dramatically enhance software performance in a wide range of applications, from secure communication to speech recognition and synthesis, and from 3D visualization and video processing to realistic physics modeling.

i dont think sse3 is important its just them 12 operations that the prescott has that the northwood doesnt have tho i think also called prescott new instructions. i might be wrong tho.

When correctly programmed for MMX, SSE, and 3Dnow all offer ways of making the processor more efficient and thus faster. A lot of programs especially games get a lot of added performance from these instruction sets.
