Depends how you define "performant". :) I don't really know enough to make a great argument but I consider that between AMD and Intel, AMD was first to commit to 64-bit and the first to say that clock speed wasn't the only consideration. Arguably they have other firsts (first to dedicated co-CPU for graphics, etc). But AMD is a fierce and creative competitor and Intel has always been big on raw power, IMO. I bet others here can add good stuff about AMD. Anyone?
