WinChip (also known as the WinChip C6) is a microprocessor designed for use in business computers that run Microsoft operating systems Made by IDT, the microprocessor reportedly provides comparable performance to Intel's more expensive Pentium microprocessors as well as to the more competitively-priced K6 and the Cyrix 6X86MX. IDT designed a smaller die area for the microprocessor, making it easier and cheaper to manufacture. WinChip cites Winstone tests that show the C6 has the highest rating per square millimeter of die area among Socket 7 microprocessors. The C6 does not include branch prediction and other features of some of the other microprocessors. It is optimized for running the most frequently used instructions and aims to be the most cost-effective choice for business applications such as word processing, spreadsheets, and database management.
