 From what I can tell it's vectorized 128-bit ops, allowing, say, 4 
floats to be added to another 4 floats in one op. Didn't we have that 
already in SSE3?  Is this just AMD's version of SSE3?  Anyone know 
what's different?

It also supports operations on 128-bit floating point values, though I 
don't know if that's mentioned in the linked article.
