Details of AMD's Radeon HD 7000M already leaking out

AMD is planning to make a significant leap in performance with a sequel to its just-launched Radeon HD 6000M video, a detailed leak gave out on Monday. The Radeon HD 7000M series should be AMD's first notebook graphics built on a much smaller 28 nanometer process and run both faster and more efficiently as a result. Donanim Haber understood that its flagship chipset, Wimbledon, would be targeted at desktop replacements and would be as much as 25 percent faster versus its yet-to-ship 6000M equivalent.

The design would focus heavily on memory with a 256-bit memory bus and between 2GB to 4GB of GDDR5 RAM. Most other details weren't given out.

Remaining chipsets would be subsets of what Wimbledon would offer. Heathrow would occupy the mid-range and have either a 128- or 192-bit interface, between 1GB and 3GB of memory and power that could in some cases work with thin-and-light notebooks. This would be about 30 percent faster than the 6000M's current mid-range, according to the tip.


At the low end would be Chelsea, a 128-bit GDDR5 design with 1GB or 2GB of memory, and Thames, a chipset designed for starter systems with only 1GB of GDDR3 memory. AMD would nonetheless expect it to double the performance of its existing entry video.

All but Wimbledon are expected to ship sometime in fall 2011 and hint at such timing for production notebooks, although they could spill into early 2012. The highest end graphics wouldn't ship until spring 2012.
