Tom's Hardware Guide got the chance to take a look into Intel's validation labs where pre-production processors and chips are carefully stressed to the bone. Nowadays the chipset giant has more than 3500 people around the globe who are involved in chip validation nowadays, up from only 200 in 1995.
Visually most impressive is the lab that is testing the processors. At the time of our visit at the end of April, the lab at the campus in Hillsboro, Oregon, held 200 debug platforms running the Smithfield (Pentium D) processor. The units generate about 500 GByte of data each week or almost 20 TByte of data during the nine month long validation process of Smithfield.
