Hi there.
MC uses MMX heavily.
The big plus for MC is getting a dual-core CPU. MC is heavily threaded in every core area of the program.
Just got my new core duo notebook. That's probably why MC works so well.
Does it need to? SSE performance improvements are typically targeted at applications that do a lot of "heavy" floating point math.
It would most probably improve or better speed up tasks in the DSP area. Isn't MC DSP module working with float math.
Just for better understanding:
Don't you need just a compiler, which is supporting sse3? You don't need new commands or code!?!
The question is just if the compiled programme would be downward compatible on processors not suporting sse3, right?
which is only supported on a small subset of newer Intel and AMD processors)?
New Core Duo PCs are all supporting sse3, as far as I understood. There are not that many new processors not supporting sse3.
Anyhow.
Interesting to know, that MC wouldn't benefit much of sse3.
