s of the time and the majority of software used in businesses. It was also designed to be a drop-in replacement for the more complex, and thus more expensive, processors it was competing with. This allowed IDT/Centaur to take advantage of an established system platform (Intel's Socket 7
).
s and adopted a 100 Mhz front side bus
to improve memory access and L2 cache performance. It also adopted the performance rating
concept, similar to how AMD and Cyrix
marketed their processors. This method of specifying processor performance helped consumers understand where the WinChip's performance fit in against Intel's competing products.
Another revision, the WinChip 2B, was also planned. This featured a die shrink to 0.25 μm, but was only shipped in limited numbers.
A third model, the WinChip 3, was planned as well. This was meant to receive a doubled L1 cache, but the W3 CPU never made it to market.

math. Its floating point performance was well below that of the Pentium, being similar to the Cyrix 6x86.
The WinChip 2 added a 3DNow!
processing unit to strengthen floating point performance, but its 3DNow! unit was not as fast as that in AMD K6-2. This successor targeted the Intel Pentium II, Cyrix MII

processors as competitors.
and the release of the Intel Celeron
processor signalled the end of the WinChip. In 1999, the Centaur Technology
division of IDT was sold to VIA
. Although VIA initially branded processors as "Cyrix," the company initially used technology similar to WinChip with its Cyrix III
line.

L1 cache CPU cacheA CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations...
TDP Thermal Design PowerThe thermal design power , sometimes called thermal design point, refers to the maximum amount of power the cooling system in a computer is required to dissipate. For example, a laptop's CPU cooling system may be designed for a 20 watt TDP, which means that it can dissipate up to 20 watts of heat...

The binary prefix kibi means 1024; therefore, 1 kibibyte is . The unit symbol for the kibibyte is KiB. The unit was established by the International Electrotechnical Commission in 1999 and has been accepted for use...
? W 2.7—2.9 V Socket 7 Socket 7Socket 7 is a physical and electrical specification for an x86-style CPU socket on a personal computer motherboard. The socket supersedes the earlier Socket 5, and accepts P5 Pentium microprocessors manufactured by Intel, as well as compatibles made by Cyrix/IBM, AMD, IDT and others.Socket 7 was...
Super Socket 7Super Socket 7The Super Socket 7, also referred to as Super 7, is an extension of the Socket 7 ZIF socket specification. It features a 100 MHz front-side bus, support for AGP, and a SPGA package. Super Socket was used by AMD K6-2 and K6-III processors, and some of the final Cyrix M-II processors...
