SSE4 support

I'm pretty sure that Conroe and derivatives have some SSE instructions beyond those included in SSE3. I kept hearing them called SSE3+ or similar, though.
 
The Conroes and other recent families of chips support the S-SSE3 (Supplemental Streaming SIMD Extensions) instruction set, also referred to by SSE3+, in addition to SSE/SSE2/SSE3, x86 and x86_64 (EM64T/AMD64) instruction sets.
 
Newegg confused SSSE3 with SSE4, as have lots of people. It would have been a lot simpler to just call it SSE4, and then call the extensions introduced with Penryn SSE5.

But oh well.
 
i think they called it SSSE3 because they didn't actually introduce any new instructions, they just made it so that some of the more complex SSE instructions could be executed in a single clock cycle instead of two. I definitely remember some early articles saying that Conroe had SSE4 though, so it certainly is confusing.
