@ 2008/07/24While technically a new part, the SB750 appears to us to be a point upgrade to the SB700. However, it is a major improvement over the SB600 used on the current 790FX boards. Anyway, let’s get into what has changed and what has not.
The SB700/750 features six SATA 3.0Gb/s ports, up from four on the SB600, with the ability to reserve up to two of those ports for eSATA connectivity. Drives can be set up in RAID 0, 1, or 10 and RAID 5 now makes its appearance in the SB750. We just received a beta set of drivers for this new feature, but at first glance, it appears to work fine at this point.
Still missing in action is a native interface for networking support. AMD continues to use an external PHY and MAC for network operations. Although performance is similar to the NVIDIA and Intel solutions, this setup does incur a cost penalty for the motherboard suppliers.
