AMD attempted to crush the 'Megahertz myth' with its Performance Rating system on this day 25 years ago
Today, a quarter of a century ago, AMD launched its AMD Athlon XP processor family and its Performance Rating (PR) naming scheme.
On this day, 25 years ago, AMD introduced its AMD Athlon XP processor family, designed to combat the widely accepted "megahertz myth" that clock speed directly determined a CPU's performance. While Intel's Pentium 4 processors dominated the MHz race, AMD aimed to shift the focus towards performance, a concept that had long been undervalued by marketers.
The company launched its Performance Rating (PR) system, which aimed to showcase the true capabilities of its processors, regardless of their raw clock speeds. AMD's PR naming system allowed the company to accurately represent the performance of its Athlon XP processors, even when their clock speeds fell short of Intel's offerings.
For instance, an AthlonXP 1800+ processor was found to outperform Intel's flagship Pentium 4 2 GHz in numerous benchmarks, demonstrating that AMD's chips were just as powerful, if not more so, than their competitors. Despite the success of the PR system, AMD eventually abandoned it five years later as the market evolved and the focus shifted towards multi-core processors.
