IBM and Georgia Tech Break Silicon Speed Record

IBM and the Georgia Institute of Technology announced today that their
researchers have demonstrated the first silicon-based chip capable of
operating at frequencies above 500 GHz -- 500 billion cycles per second
-- by cryogenically "freezing" the chip to 451 degrees below zero
Fahrenheit (4.5 Kelvins). Such extremely cold temperatures are found
naturally only in outer space, but can be artificially achieved on
Earth using ultra-cold materials such as liquid helium. (Absolute Zero,
the coldest possible temperature in nature, occurs at minus 459.67
degrees Fahrenheit).

Just a comment [sorry for the OT but has to be said].

Getting a small sample of transistors working is NOTHING like mass
producing them.

When IBM can put 250 million of them on a die, make 60K working chips a
month and do it for less than $250,000 per processor ... let me know
:-)

Yeah, but AMD would sell the same thing for $249750 and AMD's would
use 10% less power. And Oh yes, AMD's would be overclockable to
517 GHz.... but it would use a different socket. ;-)

Are you trying to say something?

So that's how you get things down to 4.5 Kelvins, just get out your jug
of liquid Helium and stick them in it. Why didn't I think of that?

A particular sample of helium may be ultra-cold... but it's just plain
wrong to describe an actual substance itself as being ultra-cold.
Give me enough pressure and I'll give you liquid helium at 500 kelvin.

But remember to put it back in the fridge when you're done.

(Well, because it's what keeps everything cold, of course! How did you
/think/ your fridge worked?)

You most certainly will not. The critical temperature of Helium is
5.2 kelvin. No amount of pressure will make it a liquid above that
temperature.

I doubt it. Look up "triple-point".
