AMD’s ATI acquisition was about bringing graphics to the portfolio with the eventual goal of integration into the CPU itself. We’ll see the first of that early next year with Llano. But as AMD goes down this integration route, it needs to make sure that its chipsets are at least up to par with Intel’s. Many have complained about AMD’s South Bridges in the past, but with SB850 we’ve actually seen some real improvement. There still appear to be some strange behaviors and I don’t like that there’s any discrepancy between AMD’s reference board and retail 890GX boards, but these results look very promising.
AMD’s native 6Gbps implementation manages to outperform both Marvell and Intel’s controllers in the 4KB random write test by a substantial margin. AMD’s sequential read speed is lower than the Marvell controller, and random read speed is lower than Intel’s 3Gbps controller. With a bit of work, AMD looks like it could have the best performing SATA controller on the market.

Good article explaining the complexities of supporting SATA 6Gbps.

There's also hope that AMD's SB controller will be getting better via BIOS/Driver updates.

Cool article, but that's par for the course with Anand.

Good read! I might be going AMD when Bulldozer releases, its nice to know their SB chip is getting much better. Now that I have the RAID bug, kinda paying attention to SB benchies XD

The bandwidth of the PCIe lanes vs. SATA 6 has never crossed my mind until I read this article!

We have to give AMD credit here. Its platform group has clearly done the right thing. By switching to PCIe 2.0 completely and enabling 6Gbps SATA today, its platforms won’t be a bottleneck for any early adopters of fast SSDs. For Intel these issues don't go away until 2011 with the 6-series chipsets (Cougar Point) which will at least enable 6Gbps SATA.

I'm surpised you haven't seen my rants about the limitation of P55.

LOL, I do stalk you a little bit but not that much!

Going to go look for them now...
