AMD will be launching its new generation of GPUs soon enough – that much was never in question. What's been secretive is when. Reports are now coming that the official launch will happen on or around October 18.
Nordic Hardware's sources claim that AMD will be launching the Radeon HD on October 18 (or October 19, depending on time zone) with the following specifications:
The Radeon HD 6870 will supposedly be a complete reference product that vendors will simply brand themselves with flashy stickers and fierce sounding names. On the other hand, the Radeon HD 6850 will be open for OEMs to customize their designs with layout changes and fancy cooling solutions.
Remember that this is still unofficial and AMD isn't providing any comment.
