Kepler Strikes Again: Gainward GeForce GTX 670 Review

Kepler Strikes Again: Gainward GeForce GTX 670 Review

After months of talking up its latest architecture, Nvidia reclaimed the single-GPU performance crown with its GeForce GTX 680, which outpaced the Radeon HD 7970 by about 7% in our tests. Kepler's arrival forced AMD to slash prices across its Southern Islands lineup.

The HD 7950 took a $60 cut to $399, making it one of the most tempting 7000 series cards because it has no equal -- or had no equal, we should say. Continuing Kepler's rollout, Nvidia has unveiled the GTX 670, which is priced against the HD 7950 at $399. Despite being $100 cheaper than the GTX 680, the GTX 670 doesn't appear to be much slower on paper, and that could spell disaster for AMD.

Claiming the Crown: Gainward GeForce GTX 680 Phantom Review

On paper, the GTX 680 has almost 200% more shader performance than the GTX 580, roughly 250% more texture performance, 90% more ROP performance and 100% more memory bandwidth. With the Radeon HD 7970 only being ~9% faster than the GTX 580, AMD appears to have priced itself into a corner this time around.

Because we didn't get a reference sample last month, our GTX 680 review will showcase one of the special edition products instead, meet the Gainward GTX 680 Phantom...

Graphics Card Overclocking: The myth put to the test

Graphics Card Overclocking: The myth put to the test

You go out to buy a new graphics card, set a budget, and it'd seem that for another $30-60 you can always go with the next step up that performs a little better. Or, you could save those extra dollars, go for the budget model and overclock it and basically match the next step up's performance.

With that in mind, we have hand-picked three graphics cards that represent select price ranges to see just how much extra value can be obtained through overclocking. For the $100+ range we have the Radeon HD 6750, the GeForce GTX 560 Ti has been used to represent the $200+ market. Then at the top of the food chain we have the Radeon HD 6970 going for $300 and up.

Gigabyte GeForce GTX 580 'Super Overclock' Reviewed

Gigabyte GeForce GTX 580 'Super Overclock' Reviewed

With most board partners scared to push the 244w GTX 580 far beyond its reference spec, we were surprised when Gigabyte announced its solution which treads on deeper water than the competition dares to.

The Gigabyte GTX 580 SOC operates at 855MHz or about double the overclock of Asus and Zotac's cards. For what appears to be a justifiable $35 premium over Nvidia's already steep $500 suggested retail price, they are adding a new PCB design and upgraded cooler.
