AMD Radeon HD 7970 GHz Edition is faster than the vanilla version and has a new feature called boost. The AMD Radeon HD 7970 GHz Edition has a standard 1000MHz core clock speed and then can dynamically boost to 1050MHz when the headroom is available. The video card monitors the power draw and temperatures and then can change the GPU frequency and voltage when needed. This allows the AMD Radeon HD 7970 GHz Edition to go up to 1050MHz on the core clock. The memory clock speed has been increased to 1500MHz and it does not dynamically change. The AMD Radeon HD 7970 GHz edition has better accuracy when it comes to power estimation and we think the hardware changes on the card were for better monitoring.
Since AMD PowerTune Technology with Boost is brand new we figured that we would include the above slide to show you how Boost works and what the Boost state is.
The Radeon HD 7970 GHz is more or less a factory overclocked Radeon HD 7970. The new vBIOS raises the default clock speed from 1000MHz (1050MHz w/ Boost) from 925MHz and the memory clock to 6GHz from 5.5GHz. The voltage was also increased from 1.175V to 1.240V These changes are done in the vBIOS and an owner of the original Radeon HD 7970 card can flash their card to the 7970 GHz Edition BIOS and get basically the same thing for free. Not all cards will be able to reach these levels, but seeing how the AMD Radeon HD 7970 GHz edition costs $499 and the Radeon HD 7970 costs $429 it might be worth trying out in order to save $70.
Since official AMD Radeon HD 7970 GHz Edition BIOS was released, so current 7970 owners are in luck if they own a reference card that can handle these new speeds. If the vBIOS flash works they should be able to attain the same performance levels as the Radeon HD 7970 GHz card. Not all AMD Radeon HD 7970 cards use the reference PCB and design, so be careful when flashing any card and understand that you are taking a risk. If you don't want to risk it then you should pay the extra $70 and just get the 7970 GHz Edition that is guaranteed to work.by nathan kirsch
