Boffins from IBM and the Georgia Institute of Technology (GIT) have produced what they claim is the world's fastest silicon chip thanks to what must be the acme of overclocking. The researchers reached a clock speed of 500GHz by reducing it's temperature to just 4.5° above absolute zero.

The feat was part of the team's exploration of fourth-generation Silicon-Germanium (SiGe) devices, which IBM and GIT are investigation for future comms chip applications. The scientists wanted to see just how fast such a chip could be persuaded to run without malfunctioning or, in extreme cases, melting.

If cooling a machine down to -268.5°C seems a trifle impractical, take heart from the boffins' other efforts, which saw the chip running at 350GHz at room temperature - rather better than the 2GHz commercial products for communications applications typically run at today. ®

Does it do hyperthreading?? :)

Quite amazing, I wonder how many decades or centuries it takes for something of that speed to get down to the mainstream? It'll probably need a big PSU....

you know 10 second superpi has been and gone already don't ya?

also, this isn't a desktop cpu overclocked, its going to be a very very very basic, little logic, possibly even just a single transistor. people have been making very basic things and seeing how far they can whack the speed up to find out theoretical limits.

whats the point of a transistor turning on and off at 500Ghz, if the logic can't work out how to add two numbers together.

anyway, stuff like this eventually leads to findings that help advance desktop/server and other chips but in and of itself means very little.

Uh oh, someone didn't spot the humour in this thread :p

Yes we all know the chip can probably barely do multiplication. That it couldn't run any modern OS. That it would be useless for pretty much any real world usages.

*News just in*

Take a look @ the 1st Psu's to power these cpu's
