AMD is preparing to update the specifications of its Radeon HD 7950 graphics processor to make it more competitive in the sub-$400 market segment, particularly against NVIDIA's upcoming GeForce GTX 660 Ti graphics processor. The update is much like that of the Radeon HD 7750, which got its core frequency increased from 800 to 900 MHz in a specifications update. The company released a new BIOS ROM image file which works on all AMD reference design Radeon HD 7950 graphics cards, which implements the new specifications.

The new specifications sees the GPU core frequency increased to 850 MHz (from 800 MHz), and introduces PowerTune with Boost, which sends the GPU clock speed up to 925 MHz, when applications demand it. 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.
