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."

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.
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.

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.

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."

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.
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.
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.
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.

SAN JOSE, Calif.—GPU Technology Conference—May 15, 2012—NVIDIA today unveiled a new family of Tesla GPUs based on the revolutionary NVIDIA Kepler GPU computing architecture, which makes GPU-accelerated computing easier and more accessible for a broader range of high performance computing (HPC) scientific and technical applications.
The new NVIDIA Tesla K10 and K20 GPUs are computing accelerators built to handle the most complex HPC problems in the world. Designed with an intense focus on high performance and extreme power efficiency, Kepler is three times as efficient as its predecessor, the NVIDIA Fermi architecture, which itself established a new standard for parallel computing when introduced two years ago.
“Fermi was a major step forward in computing,” said Bill Dally, chief scientist and senior vice president of research at NVIDIA. “It established GPU-accelerated computing in the top tier of high performance computing and attracted hundreds of thousands of developers to the GPU computing platform. Kepler will be equally disruptive, establishing GPUs broadly into technical computing, due to their ease of use, broad applicability and efficiency.”
The Tesla K10 and K20 GPUs were introduced at the GPU Technology Conference (GTC), as part of a series of announcements from NVIDIA, all of which can be accessed in the GTC online press room.
NVIDIA developed a set of innovative architectural technologies that make the Kepler GPUs high performing and highly energy efficient, as well as more applicable to a wider set of developers and applications. Among the major innovations are:
- SMX Streaming Multiprocessor – The basic building block of every GPU, the SMX streaming multiprocessor was redesigned from the ground up for high performance and energy efficiency. It delivers up to three times more performance per watt than the Fermi streaming multiprocessor, making it possible to build a supercomputer that delivers one petaflop of computing performance in just 10 server racks. SMX’s energy efficiency was achieved by increasing its number of CUDA architecture cores by four times, while reducing the clock speed of each core, power-gating parts of the GPU when idle and maximizing the GPU area devoted to parallel-processing cores instead of control logic.
- Dynamic Parallelism – This capability enables GPU threads to dynamically spawn new threads, allowing the GPU to adapt dynamically to the data. It greatly simplifies parallel programming, enabling GPU acceleration of a broader set of popular algorithms, such as adaptive mesh refinement, fast multipole methods and multigrid methods.
- Hyper-Q – This enables multiple CPU cores to simultaneously use the CUDA architecture cores on a single Kepler GPU. This dramatically increases GPU utilization, slashing CPU idle times and advancing programmability. Hyper-Q is ideal for cluster applications that use MPI.
“We designed Kepler with an eye towards three things: performance, efficiency and accessibility,” said Jonah Alben, senior vice president of GPU Engineering and principal architect of Kepler at NVIDIA. “It represents an important milestone in GPU-accelerated computing and should foster the next wave of breakthroughs in computational research.”
NVIDIA Tesla K10 and K20 GPUs
The NVIDIA Tesla K10 GPU delivers the world’s highest throughput for signal, image and seismic processing applications. Optimized for customers in oil and gas exploration and the defense industry, a single Tesla K10 accelerator board features two GK104 Kepler GPUs that deliver an aggregate performance of 4.58 teraflops of peak single-precision floating point and 320 GB per second memory bandwidth.
The NVIDIA Tesla K20 GPU is the new flagship of the Tesla GPU product family, designed for the most computationally intensive HPC environments. Expected to be the world’s highest-performance, most energy-efficient GPU, the Tesla K20 is planned to be available in the fourth quarter of 2012.
The Tesla K20 is based on the GK110 Kepler GPU. This GPU delivers three times more double precision compared to Fermi architecture-based Tesla products and it supports the Hyper-Q and dynamic parallelism capabilities. The GK110 GPU is expected to be incorporated into the new Titan supercomputer at the Oak Ridge National Laboratory in Tennessee and the Blue Waters system at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign.
“In the two years since Fermi was launched, hybrid computing has become a widely adopted way to achieve higher performance for a number of critical HPC applications,” said Earl C. Joseph, program vice president of High-Performance Computing at IDC. “Over the next two years, we expect that GPUs will be increasingly used to provide higher performance on many applications.”
Preview of CUDA 5 Parallel Programming Platform
In addition to the Kepler architecture, NVIDIA today released a preview of the CUDA 5 parallel programming platform. Available to more than 20,000 members of NVIDIA’s GPU Computing Registered Developer program, the platform will enable developers to begin exploring ways to take advantage of the new Kepler GPUs, including dynamic parallelism.
The CUDA 5 parallel programming model is planned to be widely available in the third quarter of 2012. Developers can get access to the preview release by signing up for the GPU Computing Registered Developer program on the CUDA website.

In our launch review of the GeForce GTX 670 2GB graphics card this week, we had initially mentioned that these $399 graphics cards would support SLI, 3-Way SLI and even 4-Way SLI configurations thanks to the pair of SLI connections on the PCB. We received an update from NVIDIA later on that day that in fact it would NOT support 4-Way SLI.
The message from NVIDIA was pretty clear cut:
"As I’m sure you can imagine, we have to QA every feature that we claim support for and this takes a tremendous amount of time/resources. For the GTX 680 and GTX 690, we do support Quad SLI and take the time to QA it, as it makes sense for the extreme OC’ers and ultra-enthusiasts who are shooting to break world records."
But with the similarities between the GTX 680 and the GTX 670, is there really any QA addition required to enable quad for 670? Seems like a cop-out to me man...
I saw it mostly as a reason to differentiate the GTX 670 and the GTX 680 with a feature since the performance between the cards was very similar; maybe too similar for NVIDIA's tastes with the $100 price difference.
Well this afternoon we received some good news from our contact at NVIDIA:
"Change in plans.....we will be offering 4-Way SLI support for GTX 670 in a future driver."
So while the 301.34 driver will not support 4-Way configurations with the GTX 670, 4-Way SLI will in fact be enabled after all in a future version. We'll be sure to keep you in the loop when that happens and the super-extreme enthusiasts can rejoice.
This does go to show that the fundamental differences between AMD's license-free and seemingly more "open" CrossFire technology and NVIDIA's for-fee SLI technology. With enough feedback and prodding in the right direction, NVIDIA can and does do the right thing, just look at the success we had convincing them to support SLI on AMD CPU platforms last year.
Feet to the fire everyone!
