What is the highest overclock achieved by a processor?

9GHz or something in Japan??? I'm probably wrong, but I thought I heard that around here one time.

Edit: Only 2GHz off eh 🙂? At least I got the Japan part right 😀.

7.4

That says 7.132, but it's a few months old.

ya honestly think the record is gonna last 5 months?

How do super pi times usually work out? My system took 41 seconds and this seems awful fast compared to ~18 when that is the fastest cpu in the world!

Wouldn't call it the 'fastest CPU in the world'.

Assume you create a multi-threaded version of SuperPi.
Run it on an 8core processor (or7, the cell if you wish).
at 3.2Ghz a piece, it'd do the whole thing in ~4-5 seconds.

So why is it that the times don't seem to scale well? You'd think I would be getting a much higher time at such low speeds in comparison. Just seems odd.

What does a 3.5 or 3.6 GHz 2M Prescott get in Super Pi for the same test?
Is it around 40ish? Or less?

Seeing how this would be exactly half the speed the world record holder had obtained, should Super Pi scale directly with the MHz? Example, if a 3.5 Prescott ran a 40sec Super Pi run, would a 7GHz Prescott run 20 secs? Dunno.

The highest overclocks should be separated by processor architecture. I think Intel is around 7.1 and AMD is around 3.9-4.0 from what I have seen at xtremesystems

You're assuming superpi can be multithreaded that well.
You're also still guessing on the 4-5 seconds thing, though since I doubt it's a very complicated program then it probably would do well on the Cell architecture..
