GoKawiilAMD's Athlon XP 'Performance Rating' launch turns 25
Twenty-five years ago, AMD released its Athlon XP processor line built on the Palomino core, which ran at lower clock speeds than Intel's Pentium 4 chips despite often matching or beating them in performance. To counter the industry's reliance on megahertz as a marketing yardstick, AMD introduced a Performance Rating naming scheme and the slogan 'Performance matters more than MHz.' Tom's Hardware testing at the time, led by Thomas Pabst, found Athlon XP chips beating higher-clocked Pentium 4 rivals in most benchmarks.
