Developing chip muscle through strain

The experiment is part of a project to explore the ultimate speed limits of silicon-germanium (SiGe) chips. SiGe chips are similar to standard silicon chips, but they also contain germanium for better performance and lower power consumption.
Adding germanium, however, increases the price of producing wafers and chips that come out of the wafers, so SiGe chips are typically only found in a few select markets. IBM has sold hundreds of millions of SiGe chips since it began selling them in 1998, but the cell phone industry gobbles up billions of plain silicon chips annually. (Germanium is sprinkled into standard silicon chips: Intel adds minute amounts of the element to create strained silicon in its processors).
At room temperature, the IBM-Georgia Tech chip operates at 350GHz, or 350 billion cycles per second. That's far faster than standard PC processors today, which range from 3.8GHz to 1.8GHz. But SiGe chips can gain additional performance in colder temperatures.
To that end, IBM and Georgia Tech scientists turned down the temperature and cryogenically froze the chip at minus 451 F. It's about as cold as things get. An extremely cold temperature like that is found naturally only in outer space, but can be artificially achieved on Earth using ultracold materials such as liquid helium. Absolute zero comes at minus 459 F.
SiGe chips, the scientists theorized, could eventually hit 1 terahertz, or 1 trillion cycles a second.
Ultimately, high-performance SiGe chips could be used in defense systems, space exploration vehicles and remote sensing. Conceivably, you could also build a computer for Ted Williams and other cryogenically frozen celebrities.

irrelevant.
No software maker on the planet is going to write software that
that chip cannot handle anytime soon,...
So what kind of radiation do these chips give off??
Question: If IBM created a computer chip that ran at 110GHz in 2002, don't you think it would be on the market today?

- still need to dump the clock if they really have a need for speed
