VIA and Intel have two South Bridge solutions each:
|UltraATA/66||ICH (82801AA )||VT82C686A|
|UltraATA/100||ICH2 (82801BA )||VT82C686B|
Besides their excellent modularity, VIA chipsets are very popular for their attractive prices. Today motherboards with Intel's 815 chipset can be up to $ 50 more expensive than products with a VIA chipset!
In addition, the 815 is not capable of working with two CPUs - only the 'shop-soiled' BX is. In contrast, VIA's 694X supports one or two Pentium III CPUs.
Dual Athlon systems are still not quite available yet. AMD presented a first working system a few weeks ago, but we don't expect systems to be available until Q1/2001.
