AMD shows off 28nm notebook GPU

AMD flirted and teased the tech press by showing them its first working 28nm notebook GPU.

The chip is expected to launch as part of the upcoming AMD Radeon HD 7000 series. The hacks who saw it claimed that it was running Dirt 3 – AMD’s favourite demo game – but details such as graphics settings, resolution and FPS were not revealed by David Cummings, Director of Technology Management for AMD’s GPU division.

The Radeon HD 7000 series has the codename “Southern Islands” and is being made by TSMC probably by the end of the year.

However, word on the street is that TSMC is having a few problems with its 28nm production, and it might be a while before we will see the GPUs in any volume this year.

As far as specs go it is possible to hazard a good guess even if there are no official details beyond “leaks”. We are expecting to see switchable graphics, Eyefinity, and H3D stereo 3D gaming.

NordicHardware insists that AMD is initially planning four different GPUs based on the 28nm version of the VLIW4 architecture and will use them in three different series: the Radeon HD 7800, HD 7600 and HD 7500.

If NordicHardware is right, the GPUs will be equipped with 768 to 1536 stream processors and GDDR5 memory

Further down the roadmap we expect to see the Radeon HD 7900 series featuring the new Graphics Core Next (GCN) architecture. AMD has been promising this since June and it will mean that the chips will have a GPU that performs well at both graphical and computing tasks.
