The WinChip series is a discontinued low-power Socket 7-based x86 processor that was designed by Centaur Technology and marketed by its parent company IDT.

It was of much simpler design than its Socket 7 competitors, such as AMD K5/K6, which were superscalar and based on dynamic translation to buffered micro-operations with advanced instruction reordering (out of order execution).

WinChip 2A added fractional multipliers and adopted a 100 MHz front side bus to improve memory access and L2 cache performance.

[2] It also adopted a performance rating nomenclature instead of reporting the real clock speed, similar to contemporary AMD and Cyrix processors.

[3] Although the small die size and low power-usage made the processor notably inexpensive to manufacture, it never gained much market share.
