The Inquirer claims to have measured some actual numbers regarding the Prescott's power usage. The usage of a 3.4GHz Prescott CPU is 95 Watt according to them. Overclocking the chip to 4.0GHz gives a result of 135W. But this is not a fair test, because if there will be a 4.0GHz Prescott than Intel will have probably reduced its power usage by further tweaking the CPU. Also it might be possible that Intel will not introduce a 4.0GHz Prescott because the launch of the Tejas CPUs is planned at the end of this year.
WITH THE launch of Prescott just over a week away, the power FUD continues to swirl, and there appears to be no sign of it letting up.
Rather than bitch and moan like we usually do, we decided to go out and measure the power consumption.
Before you delete your bookmarks, we will get back to bitching and moaning soon, it's just that we ran out of booze, and in a moment of clarity, decided to do something useful for a change.
So, the numbers we got for a Prescott 3.4 are 95w, perilously close to the 100w ceiling for the chips. Going a little further, if you push this chip to the limit, an OC’d Prescott at 4.0GHz consumes 135w.
Before you all write, let me answer the two questions you will all ask.
The 4.0GHz model isn’t a fair test, and the power consumption will undoubtedly come down before "official" release. The next thing will be test configuration, and the simple answer here is "no".
