nForce

The nForce is a motherboard chipset created by Nvidia for AMD Athlon and Duron (later included support in the 5 series up for intel processors). The chipset shipped in 3 varieties; 220, 415, and 420. 220 and 420 are very similar with each having the integrated GPU, but the 220 only has a single channel of memory available whereas 420 has the 128-bit TwinBank design. The 415 variant again has the dual-channel memory interface, but has no integrated graphics.
