In exactly one week from now, AMD is expected to launch its ATI Radeon HD 5850 and 5870 videocards, which as it turns out will be a precursor of more 5000 series cards to come. And you won't have to wait long, either.

According to news and rumor site DigiTimes, un-named sources at graphics cards makers have been chirping about a new series of ATI Radeon HD 5700 GPUs just around the corner. Codenamed Juniper XT and LE, the Radeon HD 5770 and 5750 should be in stores sometime in October. Both will come with 1GB of GDDR5 video memory on a 128-bit memory bus and support the recently announced multi-monitor Eyefinity technology.

Then in November, AMD will update its flagship offering with the R800-based Radeon HD 5870 X2. The reason for the slight delay, says Fudzilla, is that AMD is trying to figure out how to power and cool the dual-GPU card, which reportedly carries a TDP of 376W. By comparison, the HD 4870 X2's rated TDP is 286W.

In addition to its desktop lineup, AMD will also port its HD 5000 series over to notebooks, including the ATI Mobility Radeon 5400 for entry-level systems, 5600 for mainstream, 5700 for performance, and 5800 for high-end laptops.
