GPUs

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.

Have you been following availability of Nvidia's GeForce GTX 680? There's a lot we like about the company's flagship graphics card, but it's tough not being able to find one even a month after launch. With Radeon HD 7970s at $479, the pressure is on!

We discovered blurry textures when we reviewed the Radeon HD 7800s, so now we're performing an in-depth investigation. Why does the Radeon HD 6000 series demonstrate crisper image quality? Is performance affected? Does AMD know about the issue?

It's time to revamp the Graphics Charts section! For 2012, we're increasing the number of games and resolutions, dividing the results into three segments. But that's not all. We also include GPGPU benchmarking, power consumption, temperature, and noise.

Who needs sleep when you have caffeine? We take a second GeForce GTX 680 and run it in SLI against two Radeon HD 7970s. Then we add 5760x1080 benchmark results. Then we overclock our single-GPU flagships for a third comparison. Does our story change?

Enthusiasts want to know about Nvidia's next-generation architecture so badly that they broke into our content management system and took the data to be used for today's launch. Now we can really answer how Kepler fares against AMD's GCN architecture.

AMD's new FirePro V3900 is the company's low-profile, entry-level workstation graphics card. It's priced to compete against Nvidia’s Quadro 400. Today we're putting it up against Nvidia’s Quadro 400 and five other professional and desktop graphics cards.

We've been bugging AMD for years now, literally, to show us what GPU-accelerated software can do. Finally, the company is ready to put us in touch with ISVs in nine different segments to demonstrate how its hardware can benefit optimized applications.

There's a big hole in between AMD's $450 Radeon HD 7950 and its $160 Radeon HD 7700. Today, the company introduces Radeon HD 7850 and 7870 to fill that gap, and they push a lot more performance than we expected. But are they really ready for prime time?
