Researchers at UT are working with IBM on a new CPU architecture called TRIPS (Tera-op Reliable Intelligently adaptive Processing System). Central to the new TRIPS architecture is a new concept called 'block-oriented execution"' which will result in a processor capable of executing more than 1 trillion operations per second. A chip capable of performing 1 trillion operations, a tera-op, won't emerge from the project until 2010. However, researchers are readying a prototype chip with four processor cores--the computing units inside a processor--that is expected in less than three years. I am sure that you will NEED one of these babies to play Quake 6! More here.
