The nForce is a computer motherboard chipset created by NVIDIA for AMD Athlon and Duron microprocessors. The chipset shipped in 3 varieties; 220, 415, and 420. 220 and 420 are very similar with each having the integrated GPU, but 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.

Innovations
Dual Channel & GeForce2 MX IGP The nForce chipset was remarkable for several reasons. It 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 EV7 CPU bus was unable to take advantage of more than a single-channel DDR memory interface because the frontside bus bandwidth was equal to this. So, the second channel of the TwinBank boards went almost entirely to the IGP. In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it. ...

Ethernet and DASP NVIDIA also touted both their built-in ethernet controller, and a new memory prefetch mechanism called the Dynamic Adaptive Speculative Pre-Processor (DASP). The NVIDIA-built ethernet controller was supposedly capable of reducing CPU overhead while being also very fast. The DASP unit helped reduce memory latency for the main CPU by prefetching often needed data, or data that the DASP predicted the CPU would need. Many considered it sort of an advanced Level 3 cache device. Ethernet is a large, diverse family of frame-based computer networking technologies that operate at many speeds for local area networks (LANs). ...

nForce APU a.k.a. Soundstorm -
NVIDIA debuted their advanced NVAPU audio solution, branded Soundstorm, on the nForce MCP-D southbridge chip. It is the same as the audio processor in the Xbox chipset and supports many hardware-accelerated 2D/3D audio channels and advanced HRTF 3D audio spatialization. It also has a built-in processor for encoding computer audio into a Dolby Digital Live signal for external receivers to decode into a 5.1-channel audio spread. With its hardware acceleration, the difference in CPU usage when running popular multimedia applications was as much as 10-20%, potentially allowing faster performance in programs that are limited by the system CPU. SoundStorm was an advanced integrated 5. ...

Performance and Issues The original nForce chipset was let down by patchy driver support and less than optimal hardware design. Performance of the dual-channel memory controller and "DASP" did not greatly surpass the VIA Technologies KT266A chipset that was usually as fast and cheaper. The optimized parallel ATA driver support was introduced and then withdrawn after hardware incompatibilities showed up, and the much heralded SoundStorm audio was seen to crackle under heavily loaded scenarios. In fact, the ATA driver would remain an issue at least into the life of nForce4 where it was still known to cause problems with some hard drives and optical drives.
