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."

Due to popular request, I am going to try to keep our readers up to date on the current availability of graphics cards and pricing on the market.  With the recent price drops from AMD, the frequent out-of-stock status of the GTX 680 cards and the release of the GTX 670, I thought this would be a great summary of the current situation.

This week we have some good news!  For two full days (in a row!) NVIDIA has had GTX 680 SKUs in stock at Newegg.com.  The only downside is that two available at the time of this writing (EVGA Superclocked+ and Zotac AMP!) are priced a bit higher thanks to their overclock settings.  The EVGA part has a base clock of 1058 MHz while the Zotac has an impressive 1098 MHz base clock compared to the reference speed of 1006 MHz.  As of this post you can find the EVGA model for $539 and the Zotac option for $549.  We are almost at the point to offering up these cards in our leaderboard...  Gasp!

NVIDIA claims GTX 680 sales outpace GTX 580

Subject: Graphics Cards | May 29, 2012 - 01:56 PM |
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 Tegra 3 gets boost with LTE Support, 30 Devices this year

Subject: Mobile | May 24, 2012 - 05:05 PM |
Tagged: wayne, tegra 3, tegra, nvidia, LTE, icera, grey

In the middle of 2011, NVIDIA acquired a small company by the name of Icera, a maker of baseband and RF technologies that would eventually allow the company to integrate the two into a single chip.  As LTE-capable devices from Verizon, AT&T and even Sprint have been announced and ship, no NVIDIA Tegra-powered phone or tablet has been able to support the feature with the lone exception of the ZTE Mimosa X in February of this year.  

Today NVIDIA officially announced support and validation from AT&T on their new and growing LTE network for the Icera 410 LTE multimode chipset.  This will finally allow Tegra + LTE devices to be sold and available in the US and other markets when product manufacturers integrate the two processors in future designs.

Tegra3_Chip.jpg

As to when we will see those designs, we aren't quite sure but nothing was announced during the NVIDIA investors day today.  All we know now is that they will be coming "through this year and next."

“Validation with AT&T is an achievement that paves the way for NVIDIA Icera-powered LTE devices on the AT&T network through this year and next,” said Stan Boland, senior vice president of Mobile Communications at NVIDIA.
 
The NVIDIA Icera 410 LTE modem delivers lightning-fast web browsing, video streaming and multiplayer gaming to tablets and clamshell devices. It is the first Icera modem to implement 4G LTE in NVIDIA’s software defined radio baseband processor. Together with its multimode radio transceiver, the chipset offers 4G LTE at category 2 data rates (up to 50 Mbps) as well as 4G HSPA+, 3G and 2G compatibility.

What we DID learn at the NVIDIA investors meeting is that Mike Rayfield, GM of Tegra business unit, things we'll see as many as 30 Tegra 3 based devices for sale this year.  

NVIDIA has 30 devices planned for the year. So far, we've seen just two. Of those 30 devices, some 15 will be planned for sub-$200 pricing. That's certainly the sweet spot for impulse purchases.

NVIDIA's also looking to make inroads into the Chinese market, with 18 of those 30 tablets targeted for the Asian nation. By comparison, NVIDIA only released five devices in China in 2011, Rayfield said.

The big name to know for the rest of the year is Kai. That's the low-cost, high-performance system that NVIDIA is crowing about these days, and it's what will help bring prices down while keeping prices at a more affordable level. Will there be higher-performing tablets? Sure. But will they be $200?

Producing a number of devices, like 30, is impressive but without context the fact means very little.  How many of these devices are going to tablets and how many are phones?  How many will be running the Microsoft Win RT operating system for ARM due out in fall?  

Speaking of Icera though, NVIDIA also showed the roadmap for LTE integration including the upcoming Icera i500 LTE controller for high-end phones and tablets with newly planned integration directly on the Tegra core in a new chip called "Grey".  This new processor will run parallel with the planned 2013 release of "Wayne" though it will be targeted at smartphones and lower end tablets; Wayne is planned to find its way into higher end tablets and the onslaught of clamshells we'll see with Windows RT.

There is a lot more to learn and we expect see more news come our way as we approach Computex in Taipei!

In short, nearly two weeks later, nothing has changed.  For NVIDIA neither the GeForce GTX 690 can be found nor can the GTX 680 - a card that launched more than two full months ago.  To say we are disappointed in the capability for NVIDIA to keep up their end of the bargain would be an understatement and explains why we STILL have not used the GTX 680 card in our Hardware Leaderboard!!  The GTX 670 remains in stock though with four models available at Newegg including an overclocked MSI model for hte $399 MSRP.  Considering this might be our new favorite GPU, that is good news at least. 

AMD is still doing great on availability with the Radeon HD 7970 and HD 7950 widely available for the price of $469 / $389 with a set of three free games including DiRT Showdown and Dues Ex: Human Revolution.

NVIDIA Likely Not Recalling All 600 Series Kepler GPUs

Subject: Graphics Cards | May 21, 2012 - 03:10 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."

Ryan pitted the GTX670 and GTX570 against each other to show that in terms of gaming performance the GTX670 is a viable upgrade. [H]ard|OCP did something similar, testing the GTX670 and 680 against the HD7970 in a gaming performance showdown.  For those who are only interested in gaming performance they've assembled a great breakdown of four popular games at a variety of resolutions and both at stock clocks and the best OC they could manage.  The results are clear, for gamers it is NVIDIA with the clear win, with the GTX670 being a better value than the HD7970 and the GTX680 being a better performer.

"Wondering how the GeForce GTX 680 and GeForce GTX 670 compare to the Radeon HD 7970 and Radeon HD 7950 at stock frequencies as well as overclocked? You ask for it and we have done just that. Hold onto your hard earned cash and take note of just how the new GeForce GTX 670 compares with the rest of the competition."

Rumors About Upcoming NVIDIA GTX 680M Emerge

Subject: Graphics Cards | May 16, 2012 - 07:40 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.
