Introduction
The Soyo K7VTA-B is an updated version of the K7VTA which was released back in November 2000. The major differences are the newer 82C686B south bridge (up from the 82C686A) and better overclocking support (namely in the way of an added clock multiplier setting). Since both boards make use of the aging VIA KT133 chipset, Soyo has also released the K7VTA Pro which uses the updated KT133A. Here is a terse comparison table between the three.

The differences are small but tasty. Indeed, if you already own of these boards upgrading to another of three wouldnt be very fruitful. For everyone else in the market though, the board to buy will depend on what you need. The most expensive board will be the K7VTA Pro since it uses the newer (and thus, more expensive) chipset; this board also has the greatest longevity with its support for the 133MHz FSB AMD Thunderbirds. The cheapest is the original K7VTA, but its feature-set is also the weakest. Somewhere in between sits the K7VTA-B which well be taking a look at today.
