Intel Pentium Integrated Circuits

Perhaps the most recognized name in the microprocessor business, Intel was the first company to make the term microprocessor a house-hold word. From the first microprocessor developed in 1972 to today's 2+ GigaHertz Xeon speedsters, Intel has continually led the way in new and innovative technology and, with partner Microsoft, is largely responsible for the personal computer revolution.
