TPU reports AMD is updating the specifications of its Radeon HD 7950 to make it more competitive in the sub-$400 market against NVIDIA's upcoming GeForce GTX 660 Ti. This new BIOS increases the GPU core frequency from 800MHz to 850MHz and introduces PowerTune with Boost, which overclockers the GPU up to 925MHz, when applications demand it. The memory frequency remains unchanged.
The memory frequency stays unchanged, at 1250 MHz, and so do the physical specifications of the GPU, such as stream processor, TMU, and ROP counts. All Radeon HD 7950 graphics cards manufactured from mid-August will feature the new specifications, prices will remain unchanged. If you're familiar with manually updating the BIOS, you can check it out (at your own risk) from our VGA BIOS Database. Set your card's BIOS selector switch to "1" (if available), and update the BIOS. It works only with AMD reference-design HD 7950 cards.
