Re: AMD Zacate is faster than Intel Atom for MAME

> Not shocking - AFAIK Zacate's out of order, and Atom isn't

What amazes me is that in some benchmarking that I have read about on some sites, the Atom comes out ahead in certain programs. I have a strong suspicion that some programs are compiled with Intel specific optimizations for some or all of these. I prefer a test using good ol' gcc which I feel confident is not biased towards one processor or another.

I'm also surprised that hyperthreading has such a tangible benefit in multithreaded applications; the Zacate is consistently 60% - 80% faster than the Atom in MAME single threaded games, but in multithreaded games that drops to 25% or so. Since both processors have two real cores and the Atom has two additional 'fake' cores, the difference can I think be mostly attributed to the benefit of hyperthreading. I always thought of hyperthreading as kind of a gimmick; but I guess there really is something to it after all.
