Overclocking AMD's Radeon HD 7970 requires effective cooling, but the company's design is incompatible with most aftermarket heat sinks. Arctic and Deepcool claim to have solutions able to get the job done, without the reference cooler's loud fan.
Have the rigors of life on the road forced you to ditch your desktop in favor of a laptop? What if you could add discrete graphics to your Ultrabook? We test the gaming performance of Sonnet's Echo Express Thunderbolt expansion chassis for PCIe cards.
We have two new graphics cards in the lab today: Nvidia's GeForce GTX 650 and 660, filling the gap between its GeForce GT 640 and GTX 660 Ti with Kepler derivatives. Are these GK107- and GK106-based boards able to challenge the Radeon HD 7750 and 7850?
Seven GeForce GTX 660 Tis landed in our lab. Today, we're benchmarking them, measuring their noise and temperatures, and conducting a more in-depth analysis of the impact a 192-bit memory interface has on performance. The results are enlightening!
Sapphire gives its new flagship graphics card 6 GB of very fast memory, compared to the mere 3 GB on AMD's reference card. Does this give Sapphire's Toxic HD 7970 GHz Edition a real-world speed boost? We connect it to an epic six-screen array to find out.
Nvidia's Kepler architecture is finally manifest in a $300 graphics card, which the company says beats AMD's Radeon HD 7870 and challenges its more expensive 7950. Can this GK104-based mainstream card carve out a spot between the GCN-based competition?
AMD’s GCN architecture, known for its strong compute and 3D performance, is finally being made available in the company's FirePro workstation graphics card family. Can AMD catch Nvidia? We test the two fastest FirePro cards to answer that question.
Gigabyte’s Radeon HD 7970 Super Overclock is huge, heavy, overclocked, and very different-looking. Its Windforce 5X cooler employs five 40 mm fans. We benchmark the card, spend some time tweaking it, and measure the noise those blowers make.
Are you tired of gaming notebooks that have to be tethered to a power outlet? We test Eurocom’s Racer 2.0 to see if its combination of a 22 nm Intel-based CPU and 28 nm graphics processor from Nvidia can help enable playable performance on the road.
The good news is that it’s possible to cool AMD’s flagship Radeon HD 7970 GHz Edition to less than 75 degrees Celsius under full load, maintaining a quiet 32 dB(A) at the same time. The bad news? It'll cost you five expansion slots and more than $100.
We have seven GeForce GTX 670 cards. Which is fastest? Which is quietest? Each one swaggers onto the scene ready to prove its worth to your wallet. We emphasize thermals, acoustics, and design in this many-way shoot-out based on Nvidia's capable GK104.
With Nvidia's GeForce GTX 670 readily available for $400, AMD's Radeon HD 7950 shifts to the upper middle class of graphics card performance. We test six third-party interpretations in anticipation of pricing more in line with its competitive position.
Afox sent us its rendition of the new GeForce GT 640, based on Nvidia's GK107 GPU. This one slots in under the existing GeForce GTS 450 to do battle with AMD's Radeon HD 6670. Does the Kepler architecture deliver, or is a $100 price target too high?
Not like it was ever really widely available anyway, right? The GeForce GTX 670 offers most of GK104's on-chip resources, doesn't give up much performance, and costs $100 less. Now, let's see if Nvidia can make enough of them to satisfy demand.
Two months after the Radeon HD 7800-series cards first launched, they remain strong performers at attractive prices. We recap our coverage of the Radeon HD 7870 and 7850, discuss why we still like them, and cover one caveat for multi-GPU gamers.
Last week we reported that an engineering sample card with 768 shaders accidentally found its way into our lab instead of the HD 7850 we were expecting. This GPU may be meant for engineers, but it piqued our interest, since it happens to fill a large gap.
We already know that Nvidia's GeForce GTX 690 sports two GK104s and is priced at $1000. But hardware like this is fun to read about. Oh, you actually want to buy one? Expect performance just shy of two GTX 680s in SLI, and good luck tracking one down!
GeForce GTX 680 cards are nowhere to be found, and the Radeon HD 7970 recently dropped to a much more attractive price. We thought it was time to round up a handful of Tahiti-based cards to see how board partners are improving upon AMD's original recipe.
Did you spend some time this week wondering what Nvidia was planning for today's announcement? Everyone who guessed GeForce GTX 690, you're right. Powered by two GK104 graphics processors, we have the scoop on Nvidia's soon-to-be flagship.
