To answer the question once and for all, we set ourselves to a no-holds-barred dual-core desktop CPU fistfight. AMD submitted its five dual-core CPUs, and Intel matched with its lineup of four. We built two test beds as nearly identical as we could for the two platforms and ran each chip through a battery of tests. We then ran those results through our price-vs.-performance calculator to find out not only which is the best overall dual-core CPU in terms of raw performance but also which one offers the most bang for your buck. Skip ahead to the official ruling if you want, but the match itself is interesting.
