AMD hasn’t been rolling out any desktop chipsets ever since their 750/760MP/MPX chipsets, and it’s about fine time that they made an attempt at the chipset market again. VR-Zone brings you an in-depth article of AMD’s latest chipset, the AMD 690G in Biostar’s context, the Biostar TA690G. THe 690G consists of a RS690 Northbridge and the old SB600 Southbridge, with the main emphasis of the chipset being based on the home-theatric abilities.
Ever since the merger with ATI, AMD has been aggressively working on the various product lines by ATI, especially the chipset segment. AMD hasn’t been rolling out any desktop chipsets ever since their 750/760MP/MPX chipsets, and it’s about fine time that they made an attempt at the chipset market again. THe 690G consists of a RS690 Northbridge and the old SB600 Southbridge, with the main emphasis of the chipset being based on the home-theatric abilities. The RS690 Core consists of a modified version of the Radeon X700LE. Code named X1250, the chip runs at a core clock of 400MHz, and has 4 pixel shaders instead of the original 8 found on the X700 core. Like all onboard graphics, the X1250 core shares system memory as with graphics memory, with an option to allow up to 1GB of system memory to be utilised as graphics memory.
ATI AVIVO has been implemented into the X1250 core as it is missing from the original X700 chip. With this implementation and with die size and production costs at bay, ATI has also removed all the vertex shader units present onboard from the original 6 present. With this, All vertex shader operations will be placed on the CPU instead.
In this review, we will be taking a very close look at the graphics performance of the 690G Chipset, both discrete and integrated. Before we continue, let’s take a brief look at the specifications.
