Design issues delay R520 launch
Beyond3D has the goods on a recent ATI investor Q&A session that reveals that R520's launch has been delayed by several months.
In a recent investors Q&A session ATI’s Senior Vice President of the PC Business Unit, Rick Bergman, on the subject of R520 said “We had hoped to have that product in the June timeframe, but unfortunately due to a variety of design issues it has moved out to the September / October timeframe for launch”. This is more or less in-line with the late summer launch previously mentioned by Dave Orton.
R515 and R530 will apparently also launch in the September/October timeframe, potentially giving ATI a full lineup of next-gen products. According to Bergman, CrossFire is coming in September as well. For real this time.
