Ok I think its x86_64 ...
There's a SSE3 emlator pdf
http://xnu-dev.googlecode.com/files/SSE3%20Emulator.pdf
It describes the preformance between Native SSE3, Maxxus (now gone
), and Voodo (faster by factor of 3).
But ever since Snow Leopard, there is no "group" of people that work on the kernel anymore (ie: voodo kernel). every SL patched kernel is made by one person, and does not have the quality/tested needed to run in SSE2 only enviroment..
So the beachballing and high cpu usage is caused by the thread race/thread locking/Grand Central Dispatch problem... I guess the SSE3 emulator was still only for the 9.x.x kernel and not 10.x.x... or its missing some other SSSE3/SSSE4 (not SSE3) emulation?

and from voodo's latest news
