VIA Vs. Intel

VIA's New South Bridge: VT82C686B Supporting UltraATA/100
By

VIA and Intel have two South Bridge solutions each:

Intel VIA
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.
