Ah, I see that it is actually EM64T. A lot of people and sites call it EMT64.
And I\'m not saying that the processors are the same. I\'m saying that the technology is the same. The way that technology is implimented doesn\'t matter that much to how that technology performs. Sure, it might be the rest of the processor itself which is crap, but I wouldn\'t blame the technology, especially as I\'ve seen EM64T based processors beat AMD64 based over several benchmarks, both first and third hand. If you\'ve got equivilant processors, with Intels compiled with EM64T specific CFLAGS (Like -march=nocona) and AMD\'s compiled with amd64 specific CFLAGS (-march=K8), with the other hardware in the systems being the same, then you can compare. If EM64T really ran such buggy code, then I blame either the compiler, or the person compiling the code, because otherwise there would be widespread reports of the processors not working properly and they would have to be withdrawn.
