ATI adds "Pro" to 9100 IGP chipset
AnandTech has the first review
I've seen of ATI's new 9100 IGP Pro chipset. The 9100 IGP Pro couples an RS350 north bridge chip with an IXP 320 south bridge in an attempt to address some of the shortcomings of the original Radeon 9100 IGP. ATI has apparently optimized AGP performance and improved memory timings on the RS350 north bridge, and they're finally supporting Serial ATA with the new IXP 320 south bridge. It doesn't appear that ATI has done anything to tweak the 9100 IGP Pro's integrated graphics core, but any north bridge AGP or memory optimizations should help graphics performance.
