I would hope that higher-bandwidth GDDR3/5 could be used instead of vanilla DDR3. Further, since GDDR has more "bits" per chip, you would need fewer chips (less board cost too) to fill up a 64-bit bank of RAM while achieving higher bandwidth. 2x32-bit GDDR or 8x8-bit DDR?
Advanced Micro Devices on Tuesday officially unveiled its new core-logic set, which will become a key building block for its next-generation high-end platform code-named Leo. While the chipset does feature a number of innovations, it will hardly enable principally new kind of multimedia experience than in already available, but will rather rise performance bar of integrated platforms.
“The first of the AMD 8-series chipsets, these technologies serve as the foundation for 2010 Vision technology for AMD desktop platforms that are scheduled to be announced in the second quarter of 2010 and are designed to be compatible with the upcoming AMD Phenom II X6 six-core processor,” an official statement from AMD reads.
AMD 890GX core-logic with SB850 input/output controller supports ATI Radeon HD 4290 integrated graphics core with 40 stream processors, DirectX 10.1 and UVD 2.0 support, and 700MHz clock-speed; PCI Express 2.0 x16 with CrossFireX support; six Serial ATA-600 ports with RAID 5 support; 14 Serial ATA 2.0 ports and so on.
According to Advanced Micro Devices, many AMD 890GX-based motherboards feature SuperSpeed USB 3.0, quickly synchronizing and transferring digital media files on the new generation of USB 3.0 devices.
It is rather noteworthy that AMD has managed to speed up the launch of its new core-logic and instead of May released it commercially in March with mass production starting back in February. Mainboards based on the AMD 890GX core-logic will be available in March – April time-frame.
