AMD Starts to Ship Next-Generation Mobile Radeon HD 7000M Chips

From X-bit Labs: Advanced Micro Devices on Tuesday formally introduced its latest family of graphics processing units (GPUs) for notebooks. The new ATI Radeon HD 7000M-series chips code-named Wimbledon, Heathrow and Chelsea are made using 28nm process technology, are based on graphics core next (GCN) architecture, have higher performance than predecessors and support a number of new technologies, such as hybrid graphics Enduro, ZeroCore power tech, DirectX 11.1, Eyfinity6 and other.

As it usually happens with graphics processors for notebooks, they closely resemble their desktop brethren, but also support a number of mobile specific capabilities designed to reduce power consumption or bring other necessary functionality. In general, AMD Radeon HD 7900M (Wimbledon) is a version of Radeon HD 7800 (Pitcairn XT) chip with 1280 stream processors, AMD Radeon 7800M (Heathrow) is a flavour of Radeon HD 7770 GPU (Cape Verde XT) with 640 stream processors, whereas AMD Radeon HD 7700M is a version of Radeon HD 7750 solution (Cape Verde Pro) with 512 stream processors.

In addition to typical features offered by Southern Island family of graphics solutions based on GCN architecture, the mobile versions also offers several very important technologies.

AMD claims that over 200 of notebook designs are compatible with the new Radeon HD 7700M/7800M/7900M graphics processors. Not all of those notebooks, including those based on AMD's own accelerated processing units or Intel Corp.'s "Sandy Bridge" or "Ivy Bridge" microprocessors, will actually feature discrete graphics adapters. Nonetheless, AMD claims that the demand for such solutions exists even when it comes to ultra-thin laptops.
