AMD 890FX is the new high-end chipset for AMD
processors and ASRock 890FX Deluxe3 is a mainstream motherboard based on this
new chipset, bringing nice features like three PCI Express x16 slots, eight
SATA-600 ports, four USB 3.0 ports, solid capacitors, core unlocking utility
and more. Check it out. This new high-end chipset is a two-chip solution. The
main feature of the north bridge chip is the presence of 42 PCI Express x1
lanes – almost the double the amount present on AMD 890GX chipset (22 lanes) –
which allows a very high-end configuration for the expansion slots as we will
explain on the next page. The south bridge chip used is SB850, the same one
used on AMD 890GX chipset. The main feature of this chip is the native support
for six SATA-600 (a.k.a. "SATA 6G") ports, so the motherboard doesn't
need an external chip to support this feature, and certainly AMD 890FX and
890GX will help the new SATA standard to become mainstream. @ Hardware Secrets
