Revolution in PC Microprocessing

Friday, 11 October, 2002

Intel are be releasing a PC microprocessor with a new capability developed with the assistance of Dean Tullsen, called hyper-threading. The processor executes instructions from multiple threads/programs at once, as if they all came from a single thread. The CPU duplicates the architectural state on each processor, while sharing one set of processor execution resources. It makes one processor appear as two to the operating system.

Intel claims an average improvement of about 40% in CPU resource use providng greater throughput and improved performance.
