GeForce GTX 670 : Review

GeForce GTX 670 

While the world still waits for the GTX 680 to reach Newegg, NVIDIA has pushed ahead with the next card down in its stack: the $399 GTX 670. This more affordable option keeps most of the main Kepler credentials intact, but it necessarily makes a few compromises on the computational side, with fewer processing cores (1344 instead of 1536) and texture units (112 instead of 128) as well as slower base clock speed (915MHz instead of 1006MHz). Is that likely to be a problem? Judging from reviewers' responses published today, which cover cards from a range of vendors, probably not. In fact, as TechSpot puts it, "there's very little to critique," because the GTX 670 matches the performance of AMD's flagship Radeon HD 7970 at a much lower price. AnandTech's benchmarks put the reference board only ten percent (or a handful of fps) behind the GTX 680 in many recent games, leaving it "nipping at the 7970's heels," but it was still plenty powerful enough to play Arkham City or Battlefield 3 at 5760 x 1200 with high settings. PCPer's stats put the new card 15 to 20 percent behind the 680, but found good scaling in SLI mode. The Tech Report found the the GTX 670's cheap stock cooler let it down slightly, with a "friction-filled" idle noise well above the top-end Radeons and even above the dual-GPU GTX 690 -- but under load it conducted itself relatively well. We could go on, but ultimately if you're looking to buy this card then you'll want to do your own research at the links below, and then do a raindance.

Features

	Kepler GPU Architecture NVIDIA's Kepler GPU architecture has been designed from the ground up not just for maximum performance in the latest DirectX 11 games, but optimal performance per watt. The new SMX streaming multiprocessor is twice as efficient as the prior generation and the new geometry engine draws triangles twice as fast. The result is world class performance and the highest image quality in an elegant and power efficient graphics card.
	NVIDIA GPU Boost Up until now, GPUs have operated at a fixed clock speed when playing 3D games, even if they have the potential to run faster. GPU Boost intelligently monitors graphics work load and increases the clock speed whenever possible. The result is that the GPU always performs at its peak and you get the highest framerate possible.
	NVIDIA Adaptive Vertical Sync Nothing is more distracting than framerate stuttering and screen tearing. The first tends to occur when framerates are low, the second when framerates are high. Adaptive V-Sync is a smarter way to render frames. At high framerates, V-sync is enabled to eliminate tearing, at low frame rates, it's disabled to minimize stuttering. It gets rid of distractions so you can get on with gaming.
	NVIDIA Surround with Up To Four Monitors1 Nothing is as breathtaking as playing your favorite games across three monitors. At 5760 x 1080, the expanded field of view fully engages human peripheral vision and provides for the most immersive experience in racing and flight simulators. Add in a fourth display to keep tabs on chat, email or web while you are gaming.
	Two New Anti-aliasing Modes: FXAA and TXAA Anti-aliasing smoothes out jagged edges but can be demanding on framerates. FXAA is a new antialiasing technology that produces beautiful smooth lines with minimal performance impact. And with Kepler based GPUs, you'll be able to enable FXAA in hundreds of game titles through the NVIDIA Control Panel. The second mode, TXAA, is an in-game option that combines MSAA, temporal filtering, and post processing for even higher visual fidelity.
	NVIDIA 3D Vision® Ready2 NVIDIA 3D Vision brings a fully immersive, stereoscopic 3D experience to the PC. A combination of high-tech wireless glasses and advanced software, 3D Vision transforms hundreds of PC games into full stereoscopic 3D. Get up to 2x monitor and keyboard brightness with NVIDIA 3D LightBoost technology4. In addition, you can enjoy 3D movies and 3D digital photographs from 3DVisionLive.com in eye popping, crystal-clear quality. Learn more
	NVIDIA SLI® Technology3 Used by the most demanding gamers worldwide, SLI lets you link up to three GeForce GTX 670s together for astounding performance. And with NVIDIA’s track record for fast and frequent software updates, you’ll not only get the best performance in existing games, but future games too. Learn more
	NVIDIA PhysX® Technology Full support for NVIDIA PhysX technology, enabling a totally new class of physical gaming interaction for a more dynamic and realistic experience with GeForce. Learn more
