Intel A US corporation that is a leading manufacturer of integrated circuits (chips), particularly noted for its important range of microprocessor chips. The current range is shown in the table. The Pentium processor, Intel's most highly integrated semiconductor device, together with the previous generations – the Intel486 and Intel386 processors – run most current operating systems and support leading graphical user interfaces. In the Intel486 and Intel386 range, the standard DX suffix is replaced by SX to denote a lower-performance CPU without a built-in mathematics coprocessor, while the SL suffix is for a variant with low power consumption for mobile computers. The DX2 and DX4 ranges have doubled and tripled internal clock speeds respectively. The clock rates indicated (June 1995) are undergoing frequent upward modification.

All Intel486 and Intel386 processors are informally known by the numbers alone, and all used to have an 80 prefix. For instance, 386, 80386, Intel386 (Trademark), and i386 (Trademark) are synonymous. Preceding the 80386 range were the 80286, the 8086, and the 8088. Processors from the 8086 to the i486SX have optional math coprocessors distinguished by having a 7 in their number instead of a 6; hence the i387, i487.

Intel was the first manufacturer of microprocessors with the 4004 and 8008 chip sets. The original IBM PC and its successors and clones all used Intel processors or copies of them. In addition to its processor chips, Intel also sells system products, including both board-level products and the Paragon range of supercomputers. It is ranked number 41 in terms of revenue in the list of the world's top IT suppliers (1993 figures).
