Abit has unleashed a trio of new motherboards for the latest processors from AMD and Intel. The AN68SD, I-N73H, and I-N73HD are all based on nForce chipsets, but they target very different markets.
The AN68SD, Abit says, is aimed at both existing Socket AM2 processors and new Socket AM2+ Phenom CPUs from AMD. It's somewhat of a budget-oriented offering, as it's based on the nForce 520D chipset and includes only one PCI Express x16 slot, four 300MB/s Serial ATA ports, and one Gigabit Ethernet port. Nonetheless, it uses passive heatsinks and heat pipes to cool its chipset and processor power circuitry, and it includes some of Abit's enthusiast-oriented features including SoftMenu BIOS overclocking software and an external switch to clear the CMOS.
As for Abit's I-N73H and I-N73HD, both are microATX models based on Nvidia's GeForce 7100/nForce 630i integrated graphics chipset, and both are designed to accommodate Intel's latest processors with 1333MHz front-side bus speeds. They also feature PCIe x16 and x1 slots, four 300MB/s SATA ports, passive cooling, optical audio outputs, and HDMI as well as VGA video outputs. The only difference between the H and HD models appears to be FireWire support, which the former lacks.
