Default AMD's 890GX Chipset - Same Graphics, Better South Bridge

No news isnít always good news. AMD has been purposefully vague on the graphics specifications of its 8-series chipsets. Today we know why. The AMD 890GX has the exact same graphics horsepower as the 790GX. There havenít been any improvements to the audio side of the chipset either. The 890GX still supports 2-channel LPCM or 5.1 Dolby Digital/DTS bitstreaming over HDMI. If you want more, AMD will happily sell you a Radeon HD 5450 to plug in to your new board. Overall system performance remains unchanged. The 890GX performs no differently than the 790FX/GX chipsets.

With nothing new on the integrated graphics front, the 890GX relies mostly on its new South Bridge, the SB850, to excite. AMD first doubled the bandwidth between its North and South Bridges. Then, it added a native 6Gbps SATA controller with 6 ports, a Gigabit Ethernet MAC and two PCIe 2.0 lanes. The SB850 doesnít offer any native USB 3 support, so weíll still see motherboard manufacturers rely on NECís external USB 3 controller. The new South Bridge does support two more USB 2.0 ports as well, bringing the total up to 14.

One thing AMD neglected to mention in its press presentation about the 8-series chipset was the fact that it removed support for Advanced Clock Calibration (ACC) from AMD’s BIOS. You may remember that ACC was the nifty tool that first let us overclock Phenom processors higher, but later allowed us to unlock disabled cores on Phenom II X2, X3 and Athlon II X3 processors. You heard it right, apparently ACC is gone.
