Wow...that's old. Intel scrapped the Pentium 5. It was expected to run really fast, but they decided that GHZ isn't the most important thing ever. That's why they don't label their processors by speed anymore. It's by a number sequence, for example, the Pentium 4 is the 5xx (32-bit) and the 6xx (64-bit) series. The Pentium M is the 7xx series and the dual-core Pentium D's are the 8xx series.
