Chinese graphics card manufacturer Colorful recently showed off a massive NVIDIA GTX 680 GPU. Massive may even be an understatement, as this card uses not one, but two heatsinks – and more heatpipes that Josh can shake a GPU at – to passively cool the fastest single GPU graphics card that NVIDIA has.

While there is no word on pricing, availability, or clock speeds, the iGAME NVIDIA GTX 680 is a silent GPU that is going to need a seriously large case. One heatsink attaches as you would expect, right over the GPU, GDDR5 memory, and VRMs. It uses 140 aluminum fins and seven heatpipes traveling the length of the PCB to distribute heat.

From there, six copper heatpipes transfer heat to a second heatsink with another 140 fins and seven heatpipes(!). This second heatsink appears to float over the top of the card, supported by the six heatpipes. The heatsink and PCB are black, with a blue piece covering the two heatsinks that features the iGame and NVIDIA GTX 680 logos. The back of the card features a single DVI port, a DisplayPort, and a full-size HDMI port.

For the PC gamer that values silent performance with the least compromises possible, this card is looking like the perfect solution – assuming it comes to market, of course. If you are interested in seeing more photos of this passively cooled GTX 680 graphics card, check out the EXPReview story.

The GK107 GPU

With the release of the Kepler architecture in March of this year, NVIDIA has once again seemed to take back the hearts of PC gamers with a GPU that is both powerful and power efficient. The GK104 has seen a product implementation as the GTX 680, the dual-GPU GTX 690 and most recently as the GTX 670. With a price tag of $399 though, there is still a very large portion of the graphics card market that Kepler hasn’t touched but is being addressed firmly by AMD’s Radeon 7000 series.

Today we are going to be taking a look at NVIDIA’s latest offering, the sub-$100 card known as the GeForce GT 640 based on a completely new chip, the GK107. Specifically, we have the Galaxy GeForce GT 640 GC factory overclocked card.
 
NVIDIA’s GK107
 
Compared to the GK104 part, GK107 is a much smaller chip and the GT 640 implementation of it contains two SMX units and 384 CUDA cores. That is a significant drop off compared to the GTX 680 (1536 cores) and the GTX 670 (1344 cores) but it should really come as no surprise to those of you that follow the NVIDIA GPU families of the past.  The chip will have 32 texture units and 16 ROPs. 
 

Leaking low end Kepler specs

We will have to wait until the scheduled Computex release for verification but for right now Kitguru seems to have an idea of just what the lower end of NVIDIA's Kepler line will be like.  They are not sure of the connectivity options, especially the number of displays a single card can manage but as far as the size of the memory interface, clock speeds and size of the cards Kitguru seems fairly certain they are at least close to the actual specs.  Check out the whole list they published here.

"So far, nVidia’s launch of the Kepler range has gone smoothly. The only real hiccups have come with stock and the re-branding for some of the old 5xx cards into the 610 and 620. With the low and high ends sorted, focus for Bryan Del Rizzo moves to the mid-range and those pesky 7000 cards hanging out below £100. KitGuru spies hang around outside nVidia’s favourite KFC to see what can be overheard."

NVIDIA claims GTX 680 sales outpace GTX 580

Tagged: nvidia, kepler, gtx 680, GTX 580, GK104, fermi

During the annual investors meeting with NVIDIA top-brass and the powers that hold the money on Wall Street, an interesting slide was presented in a somewhat veiled answer to the questions we (among many others) have had to the availability and yields of their latest Kepler GPUs.

image001.png

At first glance, the graph would seem to validate claims that the stock and shipping rate of the new GeForce GTX 680 is simply unable to keep up with higher than expected and higher than normal demand.  The line on the bottom represents the GTX 580 (both lines are mislabeled as GT rather than GTX) launch, the top the GTX 680 with the lower axis represented as weeks after launch.  The vertical axis is labeled as "Units Sold Out Globally" but there are no numbers attached to it, making things incredibly vague.  

When I asked for clarification all I was really given was that "it means sales of boards from AICs to distributors, system builders, e-tailers and retailers."  This indicates that we are talking about boards either on Newegg.com, at Fry's or being sold through system builders like Maingear and Puget Systems.

NVIDIA's GTX 690 - one of the Kepler based cards MIA

The term "sold out" gave me a bit of pause - but when questioned "is it fair to translate 'units sold out globally' to 'units sold globally'?" I received an affirmative. 

If we take NVIDIA's information as it is presented, then we see that after six weeks of product availability, the GTX 680 has sold and shipped at a rate 60% higher than that of the GeForce GTX 580 which launched in November of 2010.  If that is true then we can agree with NVIDIA that demand is much higher for the GTX 680 than any other flagship GPU launch in recent memory and the continued stock and availability problems for Kepler are buyer created and strictly an NVIDIA yield issue.  

NVIDIA has told me many times that they would obviously love to have more GTX 680s to sell to consumers as having them out of stock is only costing themselves money.  How long it will take NVIDIA to balance out capacity with demand has yet to be seen though, so you can continue to check out our sort-of-weekly updates on GPU stock.

NVIDIA's big chip, the GK110

We at PC Perspective were not the only ones who became a wee bit excited when we had the news from NVIDIA about what the GK110 Kepler chip is going to be capable of.  The chip will be powering professional HPC systems with the Telsa K20 board which will deliver over a teraflop of double precision processing power.  That precision is not so important to the proper rendering of fluid dynamics in the underground water of Crysis 2 but for scientists trying to model the real world it is double what they say from the previous generation of Fermi based Tesla boards.  Check out The Tech Report as they delve into how NVIDIA tweaked their new architecture to deal with new choke points and the compute enhancements they've added.

NVIDIA Likely Not Recalling All 600 Series Kepler GPUs

Subject: Graphics Cards | May 21, 2012 - 06:10 PM |
Tagged: recall, nvidia, kepler, graphics cards, gpu

Editor's Note: We are getting a lot of flak for posting this story today, telling us that we are "giving the site credibility", referring to the Pnosker site that first started the recall rumor, simply by posting about it on our site.  Even though our post by Tim states to "take the leak with a grain of salt" and that "these GPUS go through rigorous testing and certification", some people think we were in the wrong to post about this. 

So let me be perfectly clear - the recall referenced in the story below is almost assuredly complete and utter BULLSHIT. 

According to Pnosker, NVIDIA is allegedly looking into recalling all Kepler based, 600-series graphics cards. Such a recall would affect users that have purchased GTX 670, GTX 680, and GTX 690 GPUs. The website has stated that their source has indicated that the graphics cards will possibly be recalled because the chips suffer from performance degradation after prolonged periods of heavy usage.

While their source has reportedly been correct in the past, the author cautions readers to take the leak with a grain of salt. Other websites that have picked up on this have mentioned that these GPUs go through rigorous testing and certification processes before getting to the market, so this rumor does not have much ground to stand on. Another reason to take this report with a shaker-full of salt is that if there was such a defect in the Kepler GPU, it would be more likely to completely fail rather than continue working with degraded performance.

This rumor is likely just that: a rumor. Why such a rumor was started is unknown but your Kepler graphics card purchases are probably safe from performance degradation, though they may not get as high of a boost clock as other users’ cards.

UPDATE @ 7:30pm ET: To quote from NVIDIA PR - "There is no truth to this rumor."

Rumors About Upcoming NVIDIA GTX 680M Emerge

Subject: Graphics Cards | May 16, 2012 - 10:40 PM |
Tagged: nvidia, gtx 680m, gpu, mobile, kepler

Videocardz.com managed to get their hands on some rumored details about an upcoming NVIDIA mobile graphics card–the GTX 680M. According to rumors, the mobile chip will be launched at Computex 2012 in Taiwan next month.

alleged gtx680m.jpg

There aren’t many details about the mobile chip, but it is set up to be a scaled down version of it’s Kepler based GTX 680 desktop counterpart. The GTX 680M will have approximately half as many CUDA cores at either 744 or 768 cores depending on the source. Either way, the card keeps the same 256-bit memory interface and can support SLI configurations. In addition, the 680M will be able to have up to 4GB of GDDR5 memory. Reportedly, it can use as much as 100 Watts of power.

When paired with an Intel Core i7 3720QM processor, the GPU was able to get a score of 4,905 points in 3DMark 11’s Performance present benchmark. It is supposed to be as much as 37 percent faster than the GTX 670M, which is not surprising considering that chip has only 336 CUDA cores and is clocked at 598 MHz (no word yet on what the GTX 680M will be clocked at).

No matter what the GTX 680M turns out to be, you can bet it will only be found in the highest end gaming notebooks where performance is more important than battery life. Until then, feel free to brush up on your Kepler architecture knowledge by visiting our GTX 680 (desktop) review.

GK110 Specifications

When the Fermi architecture was first discussed in September of 2009 at the NVIDIA GPU Technology Conference it marked an interesting turn for the company. Not only was NVIDIA releasing details about a GPU that wasn’t going to be available to consumers for another six months, but also that NVIDIA was building GPUs not strictly for gaming anymore – HPC and GPGPU were a defining target of all the company’s resources going forward.

Kepler on the other hand seemed to go back in the other direction with a consumer graphics release in March of this year without discussion of the Tesla / Quadro side of the picture. While the company liked to tout that Kepler was built for gamers I think you’ll find that with the information NVIDIA released today, Kepler was still very much designed to be an HPC powerhouse. More than likely NVIDIA’s release schedules were altered by the very successful launch of AMD’s Tahiti graphics cards under the HD 7900 brand. As a result, gamers got access to GK104 before NVIDIA’s flagship professional conference and the announcement of GK110 – a 7.1 billion transistor GPU aimed squarely at parallel computing workloads.

Kepler GK110

With the Fermi design NVIDIA took a gamble and changed directions with its GPU design betting that it could develop a microprocessor that was primarily intended for the professional markets while still appealing to the gaming markets that have sustained it for the majority of the company’s existence. While the GTX 480 flagship consumer card and the GTX 580 to some degree had overheating and efficiency drawbacks for gaming workloads compared to AMD GPUs, the GTX 680 based on Kepler GK104 has improved on them greatly. NVIDIA has still designed Kepler for high-performance computing though with a focus this time on power efficiency as well as performance though we haven’t seen the true king of this product line until today.

GK110 Die Shot

Built on the 28nm process technology from TSMC, GK110 is an absolutely MASSIVE chip built on 7.1 billion transistors and though NVIDIA hasn’t given us a die size, it is likely coming close the reticle limit of 550 square millimeters. NVIDIA is proud to call this chip the most ‘architecturally complex’ microprocessor ever built and while impressive, it means there is potential for some issues when it comes to producing a chip of this size. This GPU will be able to offer more than 1 TFlop of double precision computing power with greater than 80% efficiency and 3x the performance per watt of Fermi designs.
