We got wind that ATI is already readying a replacement for the recently introduced SB600 south bridge.

There are no suggestions as to when the updated SB650 south bridge will launch. However, we have learned that it will support 6 SATA 3Gbps ports with comprehensive RAID 5 functionality and we understand that it is pin-compatible with the current SB600 chip.

We believe that this is in response to NVIDIA's recently-announced nForce 500-series, which features an industry-first 6 native SATA 3Gbps ports, with the option for dual RAID 5 or a massive 6-disk RAID array.

ATI's SB600 south bridge resolves virtually all of the performance-related I/O problems that were apparent in previous south bridge implementations, namely SB400 and SB450. However, SB600 doesn't feature support for RAID 5 - everything else that you would expect in a south bridge is there.

SB650 looks as if it will bridge the gap between ATI and NVIDIA in the increasingly competitive chipset market.
