|With the acquisition of ATi earlier this year, AMD is back to making chipsets for its processors. As we all know, the next generation of processors would require HT3 for more bandwidth. CrossFire support should also scale up.|
The AMD RD790 chipset is an improvement over the RD580 or 580X chipset. The major difference is that it supports AM2+ and HT3.0.
In the test, a AMD X2 5000+ and a pair of DDR2-667 is used. The board you see comes with 4 full length PCIe x16 slots. It is fitted with 4 graphics cards. The interesting thing is that CrossFire works even with 4 cards, but performance is not ready for 4 cards to improve the performance. The PCIe slots can be configured to run in 2 by 16 or 4 by 8 in CrossFire mode. The south bridge is still the SB600.
