Asus DirectCU II Top Reviews: GeForce GTX 680 vs Radeon HD 7970


Two overclocked flagship video cards go head to head one last time

Over the past year, the GeForce GTX 680 and the Radeon HD 7970 have served as the respective flagship GPUs for each of their camps, and even though both cards seem a bit like well-aged cheese by now, they are still fast. There have also been quite a few driver updates since these cards were released, so we’ve decided to pit two of the overclocked versions against one another in a battle royale to settle this feud once and for all. Fighters, touch circuit boards and come out of your PCI Express corners. It’s time to get it on!

There are many flavors of GeForce GTX 680 out in the wild, from cards that have only modified the reference design with pretty stickers to this heavily mutated bad boy from Asus. For those not familiar with Asus nomenclature, this is the DirectCU II version of the GTX 680, meaning it features a heat pipe and fan-based cooler approximately the size of mainland China. The cooler utilizes five copper heat pipes that make direct contact with the GK104 Kepler GPU. The heat pipes fan out above the GPU and to the edge of the card, sending the heat they’ve collected into two separate heatsinks. Twin 100mm fans then blow into the heatsinks, exhausting the warm air outside of the chassis. It’s a superb design that we’ve lavished praise on before because, even though it’s a bit large, it works extremely well, and keeps the GPU just the way we like it—cool and quiet. Asus claims a noise reduction of 14dB compared to the reference design prepared by Nvidia, and we believe it even though we don’t specifically measure sound output. All this cooling takes up a bit of space, though, and this card’s triple-slot design makes it the biggest GTX 680 ever to grace our test bench.

The Asus GeForce GTX 680 DirectCU II TOP’s name is almost as long as the 11-inch card.

Some of you might be asking, “But wait, the GTX 680 already runs cool and quiet, so why is a cooler the size of Gordon Mah Ung’s anger management therapy bill required in this situation?” That’s a good question, and the answer is in the second part of our nomenclature lesson, which is the word TOP in the card’s name, which means it’s overclocked like a son-of-a-gun to the tune of 112MHz over stock speeds at 1,137MHz. Its Boost Clock gets a gentle massage all the way up to 1,201MHz, as well. Memory is not overclocked, however. The card also comes with Asus’s GPU Tweak software that lets you not only monitor the card’s temps, fan speeds, voltages, and clock speeds, but also manually adjust all those values. The card even supports an Asus-exclusive feature called VGA Hotwire that’s also supported on several Asus motherboards (it has to be supported on both to work). It lets you adjust the GPU’s voltage once you’ve soldered several wires that run from the motherboard to the video card’s PCB. This allows for control at a hardware level instead of using software, and is designed for extreme overclocking enthusiasts, to put it mildly.

During testing, the overclocked Asus GTX 680 held a crystal-clear advantage over the overclocked Radeon HD 7970, which might not be too surprising to you, but it was a surprise to us. When we tested these same video cards (not these exact cards, but reference models at stock clock speeds) just a few months ago using the latest beta drivers from each manufacturer, it was a photo finish in practically every test, with AMD holding a very slight advantage. This was a distinct coup for AMD, which had always trailed Nvidia in these comparisons previously, and it all came down to drivers, essentially. AMD had released its beta 12.11 drivers, claiming they made a significant impact on performance, and they were right.

Perhaps it’s fitting then, that this time around it is most likely drivers that have put Nvidia ahead, as we tested this card with the 310.70 version of the drivers, which were released about a month after the 12.10 drivers we used to test the Radeon card. As we were going to press, Nvidia released another version of its drivers numbered 310.90, claiming even further improvements, but they arrived too close to deadline for us to test them. However, the advantage Nvidia holds is clear, both in the benchmark numbers and frequency of driver updates. Drivers are clearly a weak point for AMD, and in this face-off it most likely made all the difference.

We should point out that the Asus card was totally silent at all times during testing, a remarkable feat given its overclocked status and its superb performance. It beat the AMD card in every test except Metro, where it lost by one frame per second, so not much of a loss, really. The numbers don’t lie, though, and as we close the book on this era of GPUs, the crown goes to the green camp, and we’ll award a crown to Asus too, for making the fastest, and most silent, GTX 680 we’ve ever tested.

Asus Radeon HD 7970 DirectCU II TOP

In the game of high-stakes poker known as the GPU industry, once a manufacturer reveals its hand, it then waits for the competition to do the same. If the competing manufacturer reveals a more powerful or desirable alternative, due to a combination of price, performance, noise, or all three, the other manufacturer will oftentimes update its lineup with a new Extreme Titanium Platinum FTW Balls-to-the-Wall Edition, which is usually mildly overclocked. We’ve seen both Nvidia and AMD do this in the past, but in this particular round it’s been AMD pulling this maneuver with its GHz edition of the HD 7970. The original HD 7970 shipped with a 925MHz core clock speed, and in order to gain a bit of an edge on the suddenly dominant GeForce GTX 680, or at least attempt to match its performance, AMD overclocked its flagship board to 1GHz and released the Radeon-based Kraken. It achieved its goal, too, as the GHz edition of the card was, for the most part, as fast as the GTX 680, or at least the two were close enough to move the argument away from performance to price and other considerations. Unfortunately for AMD, once people began to consider other factors, such as noise and heat, Nvidia still held the edge with its power-sipping Kepler architecture. While third-party manufacturers can’t do much about the card’s power output, they could certainly change its noise profile, and that’s exactly what Asus has done by adding its sizable DirectCU II cooler to this card.

Like the GTX 680, this card is also overclocked a bit and runs at 1,000MHz, which is 75MHz over its stock speeds. Its memory also has a teeny, tiny overclock up to 1,400MHz from 1,375MHz. The card includes four Display Port connectors along with one single-link DVI port and one dual-link DVI port, giving it a distinct advantage in the multiple-displays department, and allowing you to run all six displays using AMD’s Eyefinity setup for multi-monitor gaming.

During testing, the Asus card showed a mild advantage over the reference design, pulling a few frames per second out of its red-and-black hat in each test. In two games in particular, though—Dirt 3 and Far Cry 2— we saw the most improvement, though in Metro we’re still stuck in the sub-20fps region, which is simply ridiculous but not the fault of the cards, obviously. Given its overclocked nature, it’s not too surprising that it’s faster than the reference design, but what’s most impressive is how utterly silent the card is at all times; a marked improvement over the reference design, and all other HD 7970s we’ve ever tested. Sadly, the Radeon card still gets its lunch eaten by the GTX 680 in almost every benchmark, and not just by one or two frames but by enough to make it clear which card is faster. As we stated in the GTX review, it could be down to drivers, as we used the 12.10 drivers for these tests, which are the latest “official” drivers. The 12.11 drivers have been in beta for a while now and might have turned the tide had they been released, but we don’t test with beta drivers, so for now the crown goes to the green camp. To be clear, this is the best version of the HD 7970 we’ve tested in this generation of cards, but given its performance deficit to the GTX 680, we’re forced to withhold a Kick Ass award for now. Let’s hope the company can reclaim one very soon with its HD 8000 series GPUs.

‘Paper’ Developers Get $15 Million in Funding For Future Apps and Hardware [iOS Blog]

paperlogo.pngFiftyThree, the company that created popular iPad sketching app Paper, today announced that it received $15 million in funding for future projects, which will focus on both collaboration and physical creation.

We are especially focused on two areas:

TRUE COLLABORATION—Social media has changed the way we communicate, but real collaboration has been left behind. Still nothing has surpassed the simple act of sitting down in a room with a group of motivated people. We believe a breakthrough around collaboration will revolutionize the creative process. How we work together. How we discover new collaborators to work with.

PHYSICAL CREATION—Tools have helped us evolve and we’ve evolved to use tools as a way to extend our ability to express something. And that doesn’t end at the touch screen. Moving beyond touch and into the physical world of accessories opens up creating with greater dexterity and expressiveness.

FiftyThree founder Georg Petschnigg expanded on those two concepts in an interview with The Verge, explaining that the team hopes to create “a suite of mobile tools for creativity.” Currently, the company’s only app is Paper, which is an intuitive sketching app that offers a quick way to capture ideas on a distraction-free canvas.

The app, which was designed by engineers who formerly worked on Microsoft’s now-cancelled dual-screen tablet project Courier, won a 2012 Apple Design Award and was later named Apple’s iPad App of the Year.

Next Generation Consoles Needed to Save Slumping Game Sales


Xbox OneDecline In game sales just par for course.

Another month is in the books, and yet again, NPD Group noted a drop in overall game sales compared to the same period a year ago. No minor decline, total game related sales dropped 25 percent to $386.3 million from May of last year when hardwre, software, and accessories totaled $517 million, according to NPD Group’s data. Breaking it down by category, software sales fell 31 percent to $175.1 million and system sales declined by the same percentage, raking in just $96 million.

“Softness in new physical entertainment software sales stemmed from a decline in the number of new launches, with over 30 percent fewer new SKUs, as well as poor performance of the new SKUs that were released,” said NPD analyst Liam Callahan, according to USA Today.

The numbers were somehwat bolstered by consumer spending on digital sales, micro-transactions, and used game sales and rentals, all of which combined to drive total spending to around $787 million, but as impressive as that sounds, it too was the lowest of 2013.

Both Microsoft (Xbox One) and Sony (PlayStation 4) plan to launch new consoles in time for the holiday shopping season, and it’s likely the new hardware, along with developer and consumer excitement, will reverse the recent trend in consumer game spending.

Oculus Rift nets another $16 million in funding

While the Oculus Rift headset might have been initially funded by Kickstarter, this doesn’t mean that it’s funding is done with. The virtual reality peripheral has now garnered a further $16 million from investment firms, bringing aboard new executives to the Oculus Rift board of directors.

The $16 (£10) million comes from investment firms Spark Capital and Matrix Partners, with the funds earmarked for “accelerating the development of virtual reality hardware,” with the eventual plan to create a full “virtual reality platform for consumers.”

“With the recent console announcements and the advent of stronger mobile technology, we’re watching the video game industry keenly,” said one of the investors (via MCV). “In our estimation, Oculus is one of the only companies in the space with something completely new and disruptive. They have the right team, capital and vision to take virtual reality beyond console gaming and into everyday computing.”

It’s certainly come a long way since John Carmack showed off that duct taped bodge-job at E3 2012. 

As you might expect, Oculus CEO Brenand Iribe was also happy, announcing that this was a new phase of growth for the company and that with the continued support of investors and the community, they could focus on creating the best virtual reality experience available.

A new version of the Oculus Rift headset was recently unveiled at E3, giving it a full HD display behind the goggles.
