The nForce chipset introduced a dual-channel memory controller to the mainstream motherboard market, doubling theoretical throughput, and offering very competitive performance most especially in workstation class benchmarks. This dual-channel design was deemed necessary largely because of the added integrated GeForce 2 MX class video hardware. For the relatively fast integrated graphics processor (IGP) to have adequate memory bandwidth it needed more than to simply share a single memory channel with the Athlon XP CPU. In fact, the K7''s EV6 CPU bus was unable to take advantage of more than a single-channel DDR memory interface because the Front-side bus bandwidth was equal to this. So, the second channel of the TwinBank boards went almost entirely to the IGP.
