The 900 series chipset is the replacement to AMD’s 800 series so our new boards will be replacing boards like the Crosshair IV Formula, Crosshair IV Extreme, and M4A89GTD PRO to name a few. Three of our main 900 series boards are the M5A99X EVO, Sabertooth 990FX, and Crosshair V Formula. Both the Sabertooth 990FX and the Crosshair V Formula will be available at launch and the M5A99X EVO and Thunderbolt version of Crosshair V Formula will be available later.
Some of the advantages of 900 series over the 800 series as well as some ASUS specific features on our new AMD 900 series boards are USB 3.0 on the new and speedy ASMedia USB3 controller, SLI, UEFI BIOS, our DIGI+ VRM, native SATA 6G with RAID support, AI Suite II with EPU and TPU switches, Auto Tuning, optimized layout with dual slot spacing of PCI-e slots, advanced fan controls with all have at least two 4-pin fan headers that allow for fan control
These new boards are the first AMD board to have UEFI BIOS and fully support 2.2+ TB hard drives and they are the first AMD boards to feature our DIGI+ VRM for enhanced stability and overclockability. Also, these will be the first AMD chipset boards to support SLI.
The Sabertooth 990FX and the Crosshair V Formula both support 3-way SLI. The Crosshair V Formula also supports 4-way SLI using ASUS’ ROG Xpander.
To give you an idea of the performance on our 990FX boards, here are some results of various benchmarks comparisons between the Sabertooth 990FX and our 890FX ROG board, Crosshair IV Formula. The tests on both motherboards were done using an X6 1055T Thuban, 4GB of 1600MHz CAS 9 memory, and an ASUS GTX570. These tests were done with no overclocking.
