When electronics engineers and their buddies, all working at IBM, fancy some overclocking, rest assured they'll do orders of magnitude better than anybody else on the face of the earth. They took a chip all the way to 500GHz, running it at a temperature just 4.5C above absolute zero.[The Register]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.
