For a short time today I was excited to be the owner of a 120Mhz Pentium. This went beyond my standard run-of-the-mill exuberance because I thought, for a little while anyway, that I was using a machine with one of the best clock-to-power ratios on record.
Or I did, anyway. Now I’m not so sure. If I understand that chart correctly (and it’s always possible that I don’t), my lowly CPU draws around 12 watts, and cranks out CPU speed at a factor of roughly 10 times that number.
It looked good, but then I noticed that most of the rest of the page uses an inversion of that ratio to show its calculations — watts to Mhz or watts to Ghz, as opposed to the opposite. Since I’m not so much a hardware geek as to trust my ability to calculate for myself, I am either excited to own a Pentium … or now on the lookout for a 233Mhz Klamath Pentium II, since it apparently weighs in at the other end of the scale. And so I remain somewhat confused, but no less proud of my P1.
Not that it matters much, since a Pentium is still a Pentium, and knowing its power draw-to-clock frequency ratio doesn’t make it any faster. But in a day and age when people demand four, six or even 10 hours of battery life from a laptop, it’s interesting to consider where mine stands.
Now I just need to get out a calculator, and think these things through logically. …
