Radeon HD 7970 GHz edition review
We review the new Radeon HD 7970 GHz edition. The product is called GHz edition though even a little more. AMD now uses a Boost feature, exactly similar to what NVIDIA is doing on the 670/680 cards. The R7970 Ghz edition can 'boost' from 1000 MHz towards 1050 MHz if it meets the right conditions. So the board power (maximum power draw) needs to allow it to do so, if not it drops to 1 GHz or whatever board power range is allowed. Not only have there been tweaks on the GPU, no the memory clocks got overhauled as well and have been increased from 5,5 Gbps towards 6 Gbps bringing the product a good chunk of additional memory bandwidth. Overall the new values should bring the product a nice 10 to 15% performance boost opposed to the regular model.
