by Doug-Crowthers (Apr, 2012)Combined with AMD's ZeroCore and Power Gating technology, the HD 7000M series is setting up to be a very power efficient platform.
by Jarred-Walton (Dec, 2012)We expect the new "Mars" parts to be more power efficient than the outgoing Thames/Turks cores, thanks to the shrink to a 28nm process.

In recent years this has especially been the case for laptop/mobile graphics thanks to the larger volume and higher levels of integration as found on those parts, though this does have the unfortunate side effect of meaning GPU announcements get caught up in the deluge of announcements coming out of CES.
Moving on to our second confirmed product, we have a new low end SKU called the R5 M230.

AMD’s Kaveri APUs would feature the latest core architecture along with enhanced GCN graphics on a single die package.
This means that higher frequency DDR3 memory just might come in handy with Kaveri APUs to unleash the full potential of the graphics core.

Apple has determined that some AMD Radeon HD 6970M video cards used in 27-inch iMac computers with 3.1GHz quad-core Intel Core i5 or 3.4GHz quad-core Intel Core i7 processors may fail, causing the computer’s display to appear distorted, white or blue with vertical lines, or to turn black.
In a somewhat baffling piece of news this weekend, word comes that Apple has initiated an internal replacement program for the video cards on some of their mid-2011 27” iMacs.

Boost Clock allows the GPU to turbo up to a higher clockspeed so long as the GPU is under its power and temperature limits, allowing AMD to scrape every bit of thermal headroom from their GPUs.
All of these GPUs are based on the Heathrow GPU (desktop name: Cape Verde), packing 640 Stream Processors along with 40 texture units and 16 ROPs.
