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.
