Galaxy GeForce GTX 680 4 GB Pictured

Galaxy is working on a new GeForce GTX 680 graphics card. Pictures below reveal the Galaxy GTX 680 4 GB. As the name suggests, it is a non-reference design that's based on doubling the memory amount. The card features an out-of-the-box core OC of 1.10 GHz (base, boost not mentioned).

It did this, by using sixteen 2 Gbit GDDR5 memory chips. There's more to this card than its memory amount. The PCB is designed from scratch, and uses a strong 5+2 phase VRM, which draws power from 6+8 pin power connectors. The VRM appears to make use of International Rectifier-made DirectFETs. Perhaps Galaxy also went off-spec with the VRM controller, and maybe it supports a software interface. The cooler is an in-house design by Galaxy, too. It consists of a large heat-pipe fed aluminum fin array, ventilated by two 90 mm fans.

Colorful Giving GeForce GTX 680 iGame Kudan Treatment

Remember the Colorful GTX 560 Ti iGame Kudan and how it made our readers scream "overkill"? What happens when you combine an over-the-top design, the Colorful iGame Kudan, with an equally over-the-top GPU, the NVIDIA GeForce GTX 680? You get the Colorful GTX 680 iGame Kudan, the pinnacle of air-cooling for the GeForce GTX 680.

The iGame Kudan's design methodology revolves around giving users an extremely tweakable and modular cooling solution, which can not only be modified by playing with its heatsinks, but also be re-painted to suit your style. Colorful included a pastel-set the last time around. Under the hood, the card is packed by a modular VRM. The main PCB has an 8-phase digital VRM, which can be augmented by an additional 4-phase circuit on a daughterboard, which gets attached on a modified SO-DIMM slot, which goes parallel to the plane of the PCB, on its rear. The card is said to have high out of the box clock speeds, with an even higher overclocking headroom. Colorful sells in Asia and Europe.

GeForce GTX 680 Release Driver Limits PCI-Express to Gen 2.0 on X79/SNB-E Systems

Users of systems running Core i7 processors in the LGA2011 package and X79 chipset motherboards will find that their GeForce GTX 680 will not run at PCI-Express 3.0 x16 mode, using launch drivers. This is because NVIDIA decided against implementing Gen 3.0 support for the new GPU on X79/SNB-E systems, at the very last moment. Pre-launch drivers, including the driver that ships on discs with the graphics cards, will let the GPU run at Gen 3.0 mode on some X79/SNB-E systems, however the post-launch stable drivers (such as GeForce 301.10 WHQL), won't.

The specifications page of GeForce GTX 680 on GeForce.com has been updated to mention this:
GeForce GTX 680 supports PCI Express 3.0. The Intel X79/SNB-E PCI Express 2.0 platform is only currently supported up to 5GT/s (PCIE 2.0) bus speeds even though some motherboard manufacturers have enabled higher 8GT/s speeds.
Sources in the PC motherboard industry we spoke with, confirmed this change. PCI-Express 3.0 x16, for now, might only run on upcoming "Ivy Bridge" Core systems, running on motherboards with PCI-Express 3.0 compliant components. NVIDIA could be working to fix the issue.

Update 3/23, 21:56
NVIDIA courteously responded to our article, with a statement. Here's the statement verbatim:
While X79/SNB-E is a native Gen2 platform, some motherboard manufacturers have enabled Gen3 speeds. With our GTX 680 launch drivers, we will only be supporting Gen2 speeds on X79/SNB-E while we work on validating X79/SNB-E at these faster speeds. Native Gen3 chipsets (like Ivy Bridge) will still run at full Gen3 speeds with our launch drivers.

GeForce GTX 680 supports PCI Express 3.0. It operates properly within the SIG PCI Express Specification and has been validated on multiple upcoming PCI Express 3.0 platforms. Some motherboard manufacturers have released updated SBIOS to enable the Intel X79/SNB-E PCI Express 2.0 platform to run at up to 8GT/s bus speeds. NVIDIA is currently working to validate X79/SNB-E with GTX 680 at these speeds with the goal of enabling 8GT/s via a future software update. Until this validation is complete, the GTX 680 will operate at PCIE 2.0 speeds on X79/SNB-E-based motherboards with the latest web drivers.
This statement confirms our assertions made in the article. NVIDIA's statement on the GeForce.com product page originally formed the basis of this article, which we pasted verbatim, while preparing the article. Motherboard manufacturers have extensively marketed their LGA2011 products as natively supporting PCI-Express Gen 3.0 (8 GT/s). What's more, the datasheet of Intel Core i7 LGA2011 processors (refer 1.2.2) clearly mentions the PCI-Express root complex as supporting 8 GT/s. AMD Southern Islands GPUs have supported PCI-Express Gen 3.0 on LGA2011 platforms since day one.

ZOTAC Working On GeForce GTX 680 with 2 GHz Core Clock Speed

Speaking at a conference of AIC partners, ZOTAC (China) General Manager Mr. Kwai claimed that his company was working on a "Godly" GeForce GTX 680 non-reference design graphics card, with 2 GHz core clock speed. The card will be designed to demonstrate ZOTAC's engineering potential with non-reference designs. It will be ready by mid-April, 2012. Then again, there could be a catch. ZOTAC China has, in the past, designed certain bleeding-edge graphics cards exclusively for the Chinese market, which never made it to Europe and the US. ZOTAC is an NVIDIA-exclusive brand backed by OEM Goliath PC Partner, which also holds AMD-exclusive brand Sapphire Technology.

V3 Gaming PCs Now Available with NVIDIA GeForce GTX 680 Graphics

V3 Gaming, manufacturer of high-end computer systems, has announced the availability of the NVIDIA GeForce GTX 680 graphics card in all of its desktop computer systems. The NVIDIA GeForce GTX 680 is the fastest DirectX 11 card to date by a significant margin, and packs in an unbelievable amount of features, such as single-card NVIDIA Surround and NVIDIA Adaptive Vertical Sync technology.

The new NVIDIA GeForce GTX 680 graphics card is the first look at the all new "Kepler" GPU architecture that represents a significant upgrade over the previous generation in terms of both performance and functionality. NVIDIA's Kepler architecture brings massive GPU compute superiority and is designed to deliver faster, more power-efficient performance. The GeForce GTX 680 is equipped with 1536 CUDA cores arranged in the brand new SMX streaming multiprocessor configuration and 2 GB of high-speed GDDR5 memory.

Did NVIDIA Originally Intend to Call GTX 680 as GTX 670 Ti?

Although it doesn't matter anymore, there are several bits of evidence supporting the theory that NVIDIA originally intended for its GK104-based performance graphics card to be named "GeForce GTX 670 Ti", before deciding to go with "GeForce GTX 680" towards the end. With the advent of 2012, we've had our industry sources refer to the part as "GTX 670 Ti". The very first picture of the GeForce GTX 680 disclosed to the public, early this month, revealed a slightly old qualification sample, which had one thing different from the card we have with us today: the model name "GTX 670 Ti" was etched onto the cooler shroud, our industry sources disclosed pictures of early samples having 6+8 pin power connectors.

Next up, while NVIDIA did re-christian GTX 670 Ti to GTX 680, it was rather sloppy at it. The first picture below shows the contents of the Boardshots (stylized) folder in NVIDIA's "special place" for the media. It contains all the assets NVIDIA allows the press, retailers, and other partners to use. Assets are distributed in various formats, the TIFF is a standard image-format used by print-media, for its high dot-pitch. Apart from a heavy payload, the TIFF image file allows tags, that can be read by Windows Explorer, these tags help people at the archives. The tags for images in TIFF format, of the GTX 680 distributed to its partners in the media and industry contain the tag "GTX 670 Ti".

AVADirect Starts Selling NVIDIA GTX 680 Graphics Processing Unit

Today AVADirect, a leading custom computer manufacturer, announced that they are now selling the new NVIDIA GTX 680 graphic processing unit. The GTX 680 is based off of the previous 580 graphics processing unit that NVIDIA has been re-inventing for the past year. They produced ground-breaking performance benchmarks, and reached a whole new level of capabilities that were not tapped by the graphics community, until now. The GTX 680 promises to reach new heights and create a serious impact in gaming and 3D rendering performance.

NVIDIA GPU Boost Technology is similar to the Turbo Boost function seen in Intel Sandy Bridge processors. The graphics processing unit will increase the clock speed based on current demand allocated to the graphics card. If you're immersed in a game, and you come across a scenario that takes more graphics processing power, the Boost Technology will increase the core clock thus keeping gameplay as smooth as possible. TXAA Technology, developed by Nvidia, is a new form of anti-aliasing that combines core functions of FXAA to create a balance between performance and image quality. Adaptive Vertical Sync enables per your current frame rate to provide the most fluent gameplay throughout many games available. PCI Express 3.0 has recently been adopted by Intel's X79 chipset and promised increased bandwidth for more performance. By using this technology through the bus of the graphics card, performance will be heavily improved, over a PCI Express 2.0 expansion slot.
