TweakTown: NVIDIA GEFORCE GTX 680 (Kepler) 2GB Reference Video Card Overclocked

Earlier today we bought you a review on the NVIDIA GEFORCE GTX 680 2GB, and for all our personal issues with NVIDIA, we made it pretty clear that this is an absolutely awesome video card from the green team that offers some serious power.

Since that went live we've been hard at work overclocking the new model to see just how much performance we could get out of it. To do that there's only one program we used, and that's of course MSI Afterburner which has always served us extremely well when it comes to GPU overclocking.

Benchmark Reviews: NVIDIA GeForce GTX 680 Graphics Performance

Of the many platforms available for gamers to enjoy video games, there's no question that the highest quality graphics come from PC. While game developers might not consider PC gaming as lucrative as entertainment consoles, companies like NVIDIA use desktop graphics to set the benchmark for smaller more compact designs that make it into notebooks, tablets, and smartphone devices. NVIDIA's Kepler GPU architecture is an example of this, delivering unprecedented performance while operating cooler and consuming far less power than previous flagship discrete graphics cards. In this article Benchmark Reviews tests the NVIDIA GeForce GTX680 video card equipped with a 28nm GK104 Kepler GPU, and compares it against the best DirectX 11 video cards available. Featuring their new NVIDIA GPU Boost technology, the GeForce GTX 680 video card can dynamically adjust power and clock speeds based on real-time application demands.

OCC: NVIDIA GTX 680 Review

OCC has published a review on the NVIDIA GTX 680

A good bit of negative feedback is present on the Internet about how the Kepler cards overclock. Even I was worried, but after realizing that the level to which the power target can be set can not possibly cause the card to decrease its clocks, those worries went away. As soon as I saw my set clock speed steady for every benchmark, I felt loads better. So, to put this to rest, your overclocking potential is not going to be limited AT ALL! So, looping Unigine 3.0 while I was overclocking, I was able to reach 1305MHz on the core and 1628MHz (6500MHz effective) on the memory. That's nearly a 30% increase on the core and just under 10% on the memory. I was hoping for 7GHz memory here, but it couldn't quite make it. Even while pushing the card past its limit and having the overclock fail, the system never crashed. Only the graphics card driver fails, but successfully recovers. It is certainly the most painless overclocking I've had for sure; the system never locked up!

HotHardware.Com: NVIDIA GeForce GTX 680 Review: Kepler Debuts

We've been hearing about NVIDIA's Kepler architecture since about September 2010. It was back at that years' NVIDIA GPU Technology Conference, that company CEO Jen-Hsun Huang first publically disclosed that Kepler would offer massive performance per watt improvements over Fermi and previous-gen architectures and that GPUs based on Kepler would arrive in 2011. Well, the launch date has obviously slipped. How Kepler's power efficiency looks, we'll get to a little later.

The rumor mill kicked into high gear over the last few months, and has been consistently churning out more and more Kepler scuttlebutt (whether true or false) coincident with Radeon HD 7000 series launches. Today though, we can put the rumors to rest. We've had a new Kepler-based GeForce GTX 680 in hand for a couple of weeks now and can finally reveal all of the juicy details...

Hi Tech Legion: NVIDIA GeForce GTX 680 DirectX 11 Video Card Review

The release of the NVIDIA GeForce GTX 680 ushers in a new class of enthusiast GPU. The NVIDIA GeForce GTX 680 GPU is based on the new 28nm "Kepler" architecture which sports the next generation Streaming Multiprocessor (SMX) containing a massive 1536 CUDA core count. While designed to be powerful, the NVIDIA GeForce GTX 680 is also very efficient, requiring only two additional 6-pin power connectors compared to the previous generation GTX 580 as well as AMD's latest HD 7970 video card which requires extra 6-pin and an 8-pin PCI-E power connectors.

PC Perspective: NVIDIA GeForce GTX 680 2GB Graphics Card Review - Kepler in Motion

NVIDIA fans have been eagerly waiting for the new Kepler architecture ever since CEO Jen-Hsun Huang first mentioned it in September 2010. In the interim, we have seen the birth of a complete lineup of AMD graphics cards based on its Southern Islands architecture including the Radeon HD 7970, HD 7950, HD 7800s and HD 7700s. To the gamer looking for an upgrade it would appear that NVIDIA had fallen behind; but the company is hoping that today's release of the GeForce GTX 680 will put them back in the driver's seat.

Anandtech: NVIDIA GeForce GTX 680 Review: Retaking The Performance Crown

How do you follow up on Fermi?” That’s the question we had going into NVIDIAs press briefing for the GeForce GTX 680 and the Kepler architecture earlier this month. With Fermi NVIDIA not only captured the performance crown for gaming, but they managed to further build on their success in the professional markets with Tesla and Quadro. Though it was a very clearly a rough start for NVIDIA, Fermi ended up doing quite well in the end.

Engadget: Kepler comes of age: NVIDIA unveils GeForce GTX 680 desktop GPU, 600M series for laptops

NVIDIA's next-gen GPUs sure took their sweet time arriving, but the first of the Kepler crew is finally available in stores and its 28nm silicon is just itching to show off what it can do. You may be wondering what the 2GB GeForce GTX 680 brings to the gaming table, and whether it'll put an end to AMD's free run at the top of the food chain. Well, NVIDIA now claims it has "the fastest GPU in the world", with both lower power consumption and a 10-40 percent performance advantage over AMD's single-GPU rival, the Radeon HD 7970, at 1920 x 1080. How can it back up such a boast? Ultimately, everything hinges on independent benchmarks (coming soon in our review round-up), but in the meantime we need to look at NVIDIA's new architecture for clues. Intrigued? Then head on past the break.
