Currently, in term of “Single Core”-powered graphic card, Nvidia’s GTX 680 cards are still dominating the competition. But it seems AMD (ATi) does not give up easily. Its clear enough by the release of Radeon HD 7970 GHz Edition which has better and higher specifications than GTX 680, at least on the paper. But what about is overall performance, is it really faster than Nvidia’s flagship card?
First of all, lets talk about what weapons it has under the hood. Generally, it still has similar hardware of what the original 7970 has. The main difference is its ability to bump up several important specs including higher clock rate, faster texture fillrate, higher memory clock, and faster memory bandwidth.
All of those higher level specs are working in the same stream processors, texture units, memory bus, die size, numbers of transistors and also made from the same processing technology. You can find out its detail from the comparison table below (also compared to GTX680).
Performance: 7970 GHz vs GTX 680
As what you can see from the comparison table above, the GHz Edition of Radeon 7970 has better specifications which theoretically should have better performance as well. But does practically the card can out perform GTX 680 in terms of gaming as well as benchmarking? For that, folks at Tom’s Hardware did the test using 3DMark 11. Interestingly, the result shows 7970 GHz Edition is slightly a bit slower than GTX 680. That’s pretty disappointing but do remember that frequently 3DMark does not reflect the majority of our real-world benchmarks.
Which one to buy: 7970 GHz or GTX 680?
The MSRP of the Radeon HD 7970 GHz Edition is $499, which makes it about 10% more expensive than the average Radeon HD 7970, but somewhat more affordable than the average GeForce GTX 680. With card’s excellent performance, users can still boost it a little bit faster with PowerTune app. Considering its competitive pricing, Radeon 7970 is strongest candidate to be purchased. But remember that its whole performance needs more power than GTX 680.
So what do you think?
