The Intel 875P chipset (codenamed Canterwood) is very similar to the 865 in features. In fact, the 875P is essentially just the best silicon from the same line as the 865, which allows Intel to include its new Performance Acceleration Technology (PAT). PAT basically represents streamlined and aggressive memory settings, meaning you need to use the best quality RAM when running an 875P. With dual-channel DDR400 support, this has the potential to make the 875P the top Pentium 4 performance chipset.
The 875P supports AGP 8x, although at this stage there are no options for integrated graphics, which makes sense given the positioning of this chipset.
The 875P is also designed specifically to work with the new Pentium 4 with Hyper-Threading straight out of the box.
It also features Intel's CSA (Communication Streaming Architecture), which is a dedicated bus for networking straight to the memory to improve Gigabit networking performance.
The chipset also supports USB 2.0 as well as Serial ATA with RAID. Addition of AC'97 audio provides native six-channel audio on board, better than some PCI cards available separately.
