AMD Radeon HD 7970 GHz Edition: a necessary plus
AMD has set a worthy opponent against the NVIDIA GeForce GTX 680 in a few months.
We have known for a long time that the company's engineers did not settle for playing second fiddle and started developing the Radeon HD 7970 GHz Edition. As a result of this work, the "Tahiti XT2" was born, which basically regained the title of the fastest graphics card with a GPU for AMD. The flagship of the range still works with 32 active CUs, which assumes a total of 2048 shader processors (four 16-way SIMDs, 64 ALUs). The chip contains 8 ROP clusters, the total capacity of the six 64-bit memory controllers is 384 bits. This also shows that it is not worth looking for an architectural change, instead engineers made fine-tuning. "Tahiti XT2" covers the most successful chips that can reach 1,0 GHz clock speed and even more, because AMD saved NVIDIA's GPU Boost service with a hussar cut.
It's like we've seen this before. [+]
AMD PowerTune Boost
The method is able to dynamically increase the core voltage (from 1,2 volts to 1,256 volts) and the clock signal. Of course, the process only starts if the card is below the TDP limit set for it. We haven’t talked about something yet, and that is the rate of speed increase. The GPU is ideally capable of boosting up to 1050 MHz, and as the operating frequency of the 3GB GDDR5 onboard memories has also increased (from 5500 MHz to around 6,0 GHz), we can rightly assume that the Radeon HD 7970 The GHz Edition is capable of catching the Greens' GK104 miracle weapon.

"Happy Half Birthday Tahiti"
Fast, Faster, GHz Edition [+]
"Tahiti XT2" is really the necessary plus. The Radeon HD 7970 GHz Edition outperforms its predecessor by an average of 8-12%. This is just enough to put the GeForce GTX 1920 in the role of second fiddle in Full HD, i.e. 1080×680 pixel resolution. The difference increases gradually with the increase of the resolution and the application of image enhancement procedures. The main weakness of the Radeon HD 7970 GHz Edition is again the consumption and the not very steely cooling system.
