Three way graphical insanity

[H]ard|OCP has assembled a review of the two best GPUs on the planet, in triplicate.  It got off to a rough start as there is a serious issue with the last several Catalyst drivers, preventing you from using EyeFinity on Tri-Fire systems so they needed to revert to the release candidate that appeared back in January.  The NVIDIA machine was easier to configure, once they realized that for triple surround they had to stay to one monitor per card.  The PCIe lanes were provided by the ASUS P8P67 WS Revolution, which allowed these cards to really show off their stuff.  Make sure you check out the power consumption page, you may be very surprised at how little power the GTX680s needed to run.

"What do you get when you install three GeForce GTX 680 cards for 3-Way SLI and then three Radeon HD 7970 cards for Tri-Fire? You get insanely fast gaming performance and a gameplay experience that begs to be compared delivered by both. We find out which multi-display configuration is better for gaming in Eyefinity and NV Surround."

NVIDIA continues to tease, sends us a crowbar

Tagged: nvidia, crowbar, kepler

Remember when NVIDIA updated their Facebook page with "It's Coming..." and a picture that you had little chance of learning its origin?  Well the marketing team is at again, this time sending over a crowbar.  No, seriously.

"For Use in Case of Zombies Or...<NVIDIA LOGO>".  So either something BIG is coming later that I am going to need to open with said crowbar or maybe NVIDIA is partnering with Valve to announce Half-Life 3.  That second guess is just wishful thinking, sorry.

If nothing else I guess we'll thank NVIDIA for the additional weapon for the eventual zombie apocalypse until such time as they sit fit to clue me in on the joke.

Happy Monday!

NVIDIA Teases Another Graphics Card

NVIDIA is using its Facebook page at http://www.facebook.com/NVIDIAGeForce to tease another upcoming graphics cards with the following image and the subtitle of "It's Coming."

While there are zero details and the photo is about as ambiguous as it gets, we have several speculations about it.  It could be another Kepler-based graphics card like the GTX 670 or GTX 660 but more likely, we are seeing something higher end that NVIDIA wants us to get excited about.  Is NVIDIA already prepping the dual-GPU variant we are guessing as the GTX 690?

Like I said, it's basically impossible to tell based on the photo, but apparently we'll know "soon".

AMD Three for Free promo: HD 7900 Price drop & free games

Subject: General Tech, Graphics Cards | April 16, 2012 - 12:25 AM | Scott Michaud
Tagged: southern islands, price cut, amd

AMD, for a limited time and while supplies last, will bundle three games with the purchase of a Radeon HD 7900 Series graphics card. The qualifying cards, the Radeon HD 7950 (now $399) and 7970 (now $479), will be bundled with DiRT Showdown, Nexuiz, and Deus Ex: Human Revolution with The Missing Link DLC.

Getting a game bundled with your GPU is not the most unheard-of practice, but could still be a good deal regardless. Bundling three high-profile games and an expansion DLC for one of them is very likely to be a good deal however you look at it.

AMD will soon launch their “Three for Free” promotion for qualifying Radeon HD 7950 and 7970 video cards from participating resellers. With this program, AMD will throw in DiRT Showdown, Nexuiz, and Deus Ex: Human Revolution with The Missing Link DLC with their video card.

AMD’s throwing DiRT in a Showdown?

The selection of games is quite impressive but they only serve as BBQ sauce for the promotion: the HD 7000 series are receiving price cuts.

AMD is lowering the price of the Radeon HD 7970 to $479 and the HD 7950 to $399 along with the three-and-a-bit free games. Also cut in price, although not qualifying for the free games, is the Radeon HD7770 which loses $20 off of its price tag with an expected price of $139. Check out Ryan’s review for the performance of that card.

You can keep a lookout for these updated prices here on Newegg.com!

Price Cuts on AMD Radeon 7900 Series GPUs Coming Soon

Subject: Graphics Cards | April 13, 2012 - 09:31 PM | Tim Verry
Tagged: price cut, nvidia gtx 680, gpu, amd, 7970

We reviewed the AMD Radeon 7970 3GB GPU back in december (you can read that here), and then the NVIDIA GTX 680 was released and became king of the single GPU hill. And while I was hoping for price cuts in the 7900 series as a result, there were none to report.

According to LegitReviews, who questioned sources within AMD, consumers may be seeing cheaper 7900 series cards next week. Starting Monday, April 16th 2012, AMD will be cutting prices for the suggested retail prices (MSRP) of the cards. Specifically, the 7970 will be getting a price cut of $50 USD and the 7950 will get a $40 lower MSRP.

Although AMD has a slower single card on their hands, the scarcity of NVIDIA GTX 680 GPUs and decent performance of the 7970 means that price cuts aren't going to be a much as I was personally hoping for. Even more, retailers may further murk up the situation by not reducing prices as much as the full MSRP reduction due to GTX 680s being sold out. Also, there is no word on whether the 7800 series will also be getting price cuts. In the end though, at least you won't have to spend as much of your tax refund on a new GPU if you've been eyeing the 7900 series (heh) even if it's not as much as you were hoping for.

How does Sapphire's overclocked HD7970 fare against the GTX680

Subject: Graphics Cards | April 13, 2012 - 01:17 PM | Jeremy Hellstrom
Tagged: gtx680, hd7970, factory overclocked, sapphire

In one way, the Sapphire HD 7970 OC Edition wins this competition because of the simple fact that you can actually buy it.  However, we are also interested in the performance difference as you can occasionally find a GTX 680 for sale, so we need to know how the overclocked HD7970 performs.  Sapphire has placed two separate overclocked BIOSes on this card, one with a 950MHz core and 1425MHz memory as well as a more aggressively set one with a cores of 1000MHz and 1450MHz on the memory.  As it turned out [H]ard|OCP was never able to get the more aggressive BIOS to work, on the other hand when they manually overclocked it they hit 1150MHz core and 1860MHz for the memory at which speeds the card triumphed over the GTX 680 in every test.  Sapphire's card is ~$75 more than a GTX680 but remember, you can actually buy one.

"The Sapphire HD 7970 OC Edition video card has arrived and brings promise of low temperatures with Sapphires Dual-X Cooling System. It also features a Dual BIOS with both a passive and more aggressive profile. Will Sapphires highest end HD 7970 be able to keep up and compete with NVIDIA's flagship GeForce GTX 680?"

More leaks about NVIDIA's Dual-GPU GTX 690? May be?

Subject: General Tech, Graphics Cards | April 10, 2012 - 07:18 PM | Scott Michaud
Tagged: nvidia, leak, GTX 690

More information has surfaced about NVIDIA’s GeForce GTX 690 video card. While other tidbits came to light, perhaps most interesting is the expected May release.

NVIDIA has suffered from quite a few leaks near their launch of the GeForce GTX 680 GPU and its associated cards. Benchmarks were accidentally published early and product pages were mistakenly posted premature. The hot streak continues.

It may be time to just reset fate and skip to the GTX 700-series. I mean they will eventually be rebranded 700-something anyway.

I kid, I kid.

Not many specifications were leaked, although there is not much left that cannot already be assumed about the card due to the similarities with its sister part.

The reference model GTX 690 will require two 8-pin power connectors and output via three DVI ports as well as a mini DisplayPort. The already released GTX 680, by contrast, requires two 6-pin connectors and outputs by two DVI, an HDMI, and a full size DisplayPort.

The new card will require more power for its dual GK104 GPUs as the larger power connectors would suggest. While the GTX 680 is happy with 550W of total system power, the GTX 690 would like a system power supply of at least 650W. Since the 680 is expected to draw a maximum of 195W, an extra 100W would put estimates for the 690 power draw at somewhere around 295W.

Unfortunately estimates based on rated total system power are very inaccurate as power supply requirements are often raised to the nearest 50W. Really, the 690 could be anywhere between 245W and 295W and even those figures are just estimates.

Still, it looks as though my 750W power supply will survive past May when the leak claims that the GTX 690 is expected to arrive. Yay! May!

Just Delivered: MAINGEAR SHIFT with 3x Radeon HD 7970 Cards!

Tagged: shift, maingear, just delivered, HD 7970, 7970

Just Delivered is a section of PC Perspective where we share some of the goodies that pass through our labs that may or may not see a review, but are pretty cool none the less.

While we get sent complete system builds from time to time, it's pretty rare when they actually impress me.  Because we review and work with the best harware in the business on a daily basis, something unique really has to be there for us to really be wowed.  Today we were playing with a custom built MAINGEAR SHIFT machine that did just that.

The SHIFT is the company's flagship product line that starts out with an $1800+ price tag, so you know you are getting top of the line components.  Our test system includes a Core i7-3960X Sandy Bridge-E processor as well as a trio of Radeon HD 7970 cards from AMD.  That's right, three.

The internals are lit by a white LED and the black/red color pattern of the graphics cards is continued with the inclusion of matching Corsair DDR3 memory to the tune of 16GB and the MAINGEAR EPIC 180 self-containted water cooler.

Corsair's AX1200 watt power supply is included in the build and it is necessary!  During our testing so far we found the PC could draw as much as 1050 watts from the wall while running 3DMark11.

Another exclusive feature for the MAINGEAR systems is the EPIC Audio system that adds studio quality audio headphone output and microphone input.  The licensed Aphex technology is touted by the company as being really impressive and I am looking forward to giving it a try this week.

With our time with the SHIFT so far, the build quality has been impressive, the lack of crapware on the system is a welcome change and the performance is simply astounding as we expected with a SNB-E CPU and triple HD 7970s in CrossFireX.  

Expect more very soon!

Overclocked Gigabyte WindForce GTX 680 GPU Pictured

Popular motherboard manufacturer Gigabyte is the latest company to debut a custom version of the NVIDIA GTX 680 reference graphics card. Gigabyte’s unique take on the GTX 680 starts off with a custom dark blue PCB and ripping out the puny two six pin PCI-E power connectors. They are then replaced with one eight pin and one six pin PCI-E power connector. Then, they top it off with a custom three fan cooler. The heatsink uses three copper heatpipes with direct contact with the GPU, and two arrays of aluminum fins.

The cooler and blue PCB via VR-Zone

The extra power provided by the eight pin PCI-E connector allows for potentially higher overclocks (depending on the particular chips), and the custom cooler keeps the overclocked card nice and cool. In fact, Gigabyte is shipping the card with a factory overclock. Although they did not overclock the 2 GB of GDDR5 memory from stock, they have set the base clock frequency and boost frequency at 1071 MHz and 1124 MHz boost respectively. Compared to the reference specs of 1006 MHz base and 1058 MHz boost, that amounts to a respectable 65 MHz base overclock and 66 MHz boost overclock out of the box. Further, depending on the chip, they may be capable of overclocking much higher.

So long as you can find one in stock, the NVIDIA GTX 680 GPU is shaping up to be an interesting card, especially the custom versions! More photos of the previewed Gigabyte GTX 680 WindForce edition is available here and here.

NVIDIA Introduces Two New Rebranded 600 Series Cards

Subject: Graphics Cards | April 5, 2012 - 08:37 PM | Tim Verry
Tagged: rebranded gpu, nvidia, gtx 620, gtx 605, gpu, fermi

NVIDIA is continuing the infuriating practice (though they aren't alone in doing so) of re-branding older graphics cards into the following generation to present “new” cards (or to confuse consumers and tech journalists to no end, though I suspect that’s just a side benefit). Specifically, they are taking two lower tier desktop OEM cards and rebranding them as 600 series "Kepler" cards. The NVIDIA GT 520 and GT 510 will be renamed the NVIDIA GT 620 and GT 605 respectively. Even more confusing is that the “new” cards will have less hardware, and the only addition is the support for the OpenGL 4.2 standard (versus 4.1 on the 520 and 510).  Other than that, they are two Fermi based cards in Kepler clothing.

The NVIDIA GT 620 replaces the GT 520 and features half of the graphics memory as the 500 series card, meaning that users will get 512 MB or 1 GB on the 620 instead of the 1 GB / 2 GB options of the GT 520. The card still features VGA, DVI, and HDMI video outputs. The remaining specifications can be seen in the chart below. Despite halving the memory, the new card has a very slightly higher TDP at 30 watts versus the rated 29 watts of the GT 520.

On the other hand, the NVIDIA GT 605 is the new version of the GT 510. The 600 series part also halves the amount of memory of the GT 510 counterpart with 512 MB and 1 GB versions compared to 1 GB and 2 GB versions of the GT 510. The GT 605 also has VGA, DVI, and HDMI ports. It is rated at a TDP of 25 watts like the GT 510.

Reference GT 500 and GT 600 Series Specifications (changes in bold).

According to Tom’s, the “new” cards are still Fermi based despite the new implied Kepler generation naming scheme. Granted, these are OEM cards but it still is a bit dishonest to rebrand them, especially in the case of the GT 620 where it is the same rank but with the Kepler generation digit at the beginning. There have been some comments around the Internet that the two new rebranded cards were brought into play to allow OEMs to sell PCs with new 600 series discrete graphics. At this level, it really doesn’t matter per se as they will still do HTPC and desktop graphics well enough and are not going to be purchased by customers directly, but it’s still annoying (heh). What do you guys think about the graphics card rebranding in general, whether it’s on the desktop or mobile market?

Penguins made it to the Southern Islands - Ubuntu and the HD 7950

Phoronix revisited the performance the HD 7950 on the new Catalyst driver for Linux as it is no longer labelled as unsupported hardware.  That means that not only are the default clocks correct, you can use aticonfig/amdconfig to overclock the cards if you so desire.  The scaling of the card now matches the clock speed nicely and shows an improvement from the HD 6950 in the benchmarks.  You might not be able to find a Linux game which will take advantage of the full feature set and power of the HD 7950 but the card is capable of far more than providing you with pixels to slaughter.

"Here are some updated benchmarks of the AMD Radeon HD 7950 "Southern Islands" graphics card under Linux with the proprietary Catalyst driver."

NVIDIA urges you to program better now, not CPU -- later.

Subject: Editorial, General Tech, Graphics Cards, Processors | April 4, 2012 - 04:13 AM | Scott Michaud
Tagged: nvidia, Intel, Knight's Corner, gpgpu

NVIDIA steals Intel’s lunch… analogy. In the process they claim that optimizing your application for Intel’s upcoming many-core hardware is not free of effort, and that effort is similar to what is required to develop on what NVIDIA already has available.

A few months ago, Intel published an article on their software blog to urge developers to look to the future without relying on the future when they design their applications. The crux of Intel’s argument states that regardless of how efficient Intel makes their processors, there is still responsibility on your part to create efficient code.

There’s always that one, in the back of the class…

NVIDIA, never a company to be afraid to make a statement, used Intel’s analogy to alert developers to optimize for many-core architectures.

The hope that unmodified HPC applications will work well on MIC with just a recompile is not really credible, nor is talking about ease of programming without consideration of performance.

There is no free lunch. Programmers will need to put in some effort to structure their applications for hybrid architectures. But that work will pay off handsomely for today’s, and especially tomorrow’s, HPC systems.

It remains to be seen how Intel MIC will perform when it eventually arrives. But why wait? Better to get ahead of the game by starting down the hybrid multicore path now.

NVIDIA thinks that Intel was correct: there would be no free lunch for developers, why not purchase a plate at NVIDIA’s table? Who knows, after the appetizer you might want to stay around.

You cannot simply allow your program to execute on Many Integrated Core (MIC) hardware and expect it to do so well. The goal is not to simply implement on new hardware -- it is to perform efficiently while utilizing the advantages of everything that is available. It will always be up to the developer to set up their application in the appropriate way.

Your advantage will be to understand the pros and cons of massive parallelism. NVIDIA, AMD, and now Intel have labored to create a variety of architectures to suit this aspiration; software developers must labor in a similar way on their end.

Tagged: NVIDA, gtx 680, reviewer guide

A long held tradition in the hardware reviewing world is to accuse reviewers of biasing their reviews by only running the benchmarks that the manufacturer wants you to run and providing slanted results.  It really doesn't matter if every single site comes out with similar results, for some if a review doesn't fit their personal bias it is obviously flawed.  As [H]ard|OCP mentions, there was a time when Reviewer's Guides did resemble something along those lines but they have changed over time as suppliers realize the more biased they attempt to make their guidelines, the less likely a review site is to follow them. 

These guides are now more of a mix between a white paper and a lengthy PR release, with relatively in depth discussions on the capabilities of the product along with highlights of what the company feels are the key features on the new product.  [H] has posted the document which arrived with their GTX 680, discussing features and yes ... suggesting the appropriate games with which to show off their cards features, though what game could you test PhysX with other than Batman?

"Many times we have been asked what exactly CPU and GPU companies "require" of us when working on a review of yet-to-be-released hardware. Published here is the Reviewers Guide from the recent NVIDIA GeForce GTX 680 launch in its entirety. Besides it being a great geeked-out read, you will likely learn a few things."

The name of the game in [H]ard|OCP's latest review is scaling at 5760 x 1200, specifically the scaling of two GTX 680s in SLI as well as a pair of HD 7970s in Crossfire.  Some games like Mass Effect 3 will not benefit much as the difference between 150fps and 170fps will be hard to do but others such as Battlefield 3 and Arkham City stress these cards somewhat at this resolution, but even 50fps is rather impressive when pushing about 7 million pixels.  Read on and be prepared to feel a little jealous, maybe jealous enough to snatch up a Galaxy model which is back in stock. (didn't last 2 minutes)

"We've got two GeForce GTX 680 video cards to test SLI performance against Radeon HD 7970 CrossFireX. Will these less expensive GTX 680 video cards offer a better gameplay experience or choke at high resolutions due to a smaller VRAM footprint?

Galaxy Readying 4GB and Hall Of Fame Edition GTX 680 GPUs

Subject: Graphics Cards | March 26, 2012 - 11:36 AM | Tim Verry
Tagged: nvidia, gtx680, gpu, galaxy, 4gb gtx 680

A new article over at Chinese site EXP Review suggests that graphics card manufacturer Galaxy is gearing up with three new NVIDIA GTX 680 graphics cards. Among the new GTX 680 GPUs pictured, Galaxy is planning a reference card, a heavily overclocked Hall Of Fame card, and models with 4 GB of GDDR5 memory.

Galaxy is upping the memory ante with a new NVIDIA GTX 680 that has 4 GB of memory - twice that of the reference cards. The card will use Hynix memory chips (8 on the front, 8 on the rear of the card), an improved 5+2 phase power supply with DirectFET replacements for the usual MOSFET design. In addition, the card features 6+8 pin PCI-E power connectors and an aftermarket Galaxy Gemini cooler. The Gemini HSF uses heatpipes and an aluminum fin array cooled by two 90mm fans to cool the card. The extra cooling enabled Galaxy to offer the new card with a 10% factory overclock, for a base clockspeed of 1.1 GHz.

The other interesting card is the upcoming Galaxy GTX 680 Hall of Fame edition. This card is based on a white PCB with two 8 pin PCI-E power connectors (like those of the Asus DirectCU II and MSI Lightning). Further, it is cooled with three 90mm fans and five heatpipes leading to an aluminum fin array. The card will come equipped with dual BIOS support and overclocking software. It is not directly stated, but the Hall of Fame edition should be more overclockable thanks to the expanded cooling solution. Also, it may come with 4 GB of memory like the card above.

In our PCPer Live Review, it was stated that while NVIDIA could do reference cards with 4 GB of memory, they chose not to in order to hit certain price points and profit margins. Instead, they left it up to the Add In Board partners to offer cards with extra RAM and factory overclocks. Galaxy is prepping their 4 GB cards, but theya re not likely to be the only vendor offering cards with increased memory.  More photos are available over at EXPReview.

With an Intel Core i7 3960X, 16GB of DDR3, an ASUS Rampage IV Formula motherboard and an Enermax Platimax 1500W PSU, Hardware.Info took four GTX 680s and started benchmarking.  Of course, that means more than one monitor so these benchmarks are at 5760x1080 and due to the new architecture some games were not quite sure what to do with the extra graphics cards.  Some games like Metro 2033 were not able to provide significant scaling at high resolutions but then again Crysis 2 had no idea what to do with three HD 7970s which makes it hard to determine a clear winner between three HD 7970s and four GTX 680s.  The benchmark results offer results we've never seen, with over 80fps from the NVIDIA cards on Crysis 2 and 130fps on Skyrim.  The end result is that apart from games which seem to need updating, the scaling of the GTX 680 is impressive and it pulls less power than the HD 7970s.

"We just published a comprehensive GeForce GTX 680 4-way SLI review on Hardware.Info. Since we are the first to extensively test a Quad-SLI configuration of nVidia's brand new GeForce GTX 680, we wanted to make these exciting results available to a wider audience and created an English version of the article."

After a fun filled week of speculation, accidental launches and more leaks than a cruise ship, we can finally talk about the GTX 680 and how it performs.  Start out at [H]ard|OCP who put four monitors on a GTX 680 and started benchmarking.  The card is made with TSMC's 28nm process, sports 3.54 billion transistors and both its GPU and 1536 CUDA cores run at the same 1.006GHz and the 2GB of memory is running at 6GHz on a 256-bit bus.  That is enough power to surpass the performance of AMD's HD 7970 and surprisingly it often draws less power than the Radeon making the card more efficient than AMD's offering and ruining NVIDIA's reputation for power hungry, hot running cards.

You can catch not only the print version of Ryan's GTX 680 review but if your timing is good you can catch a recording of the live stream he did earlier today!

The Inquirer is also worth checking out as they offer a dissenting opinon which places the performance of the GTX 680 as lower than an HD 7870, let alone the 7970!

"The silicon we have all been waiting for is here. NVIDIA is launching its next generation GeForce GTX 680 video card, poised with the new flagship GPU from NVIDIA. Can it compete with AMD's Radeon HD 7970? We were somewhat amazed at how this NVIDIA GPU does when it comes to gaming, pricing, efficiency, and features."
