No it measures CPU speed, memory, etc under the assumption that scaling these provide some kind of tangible benefit to warrant the idea that we’re getting “more computer for less money” but these benefits are clearly nowhere even close to a linear relationship with CPU speed.

Productivity was an example of a benefit I chose off the cuff but you could choose others. Are today’s video game consoles 1000X more fun than a NES? Given that many people actually prefer old NES games and are even willing to pay inflated prices to collect them suggests the answer is a resounding no.
