Introduction

Is there anything sexy about PC components? For about 99% of the population, the answer is probably no. But since you're reading this, chances are that you've fallen in love with the design of a component at least once. Maybe the draw was strong enough to reel you into the world of enthusiast computing, where the skill of overclocking is revered, cable management is a compulsion, and upgraded cooling is not just an option, it's a necessity.

 

For sure, we've seen our fair share of hot deigns throughout the years, but few have spoken to our inner enthusiast quite like the DirectCU II product line from industry heavyweight, Asus. At first glance, you can tell these cards were spawned specifically for discriminating users who appreciate the finer details that make one product stand out from another. Aggressive design? Check. Black PCB? Yup. Red racing stripes? Yes they did. Triple slot cooler? Whoa.

Today, we're looking at five DirectCU graphics cards from Asus: the GTX 580, GTX 570, HD 6970, HD 6950, and HD 6870. They span the high-end and mid-range spectrum within the GPU market, with representatives from both NVIDIA GeForce and AMD Radeon product lines. Of course, all come factory overclocked while sporting massive coolers with redesigned PCBs and enhanced components. If you're into enthusiast level hardware, especially graphics cards, you don't want to miss this article. Read on to find out what DirectCU is all about and if one of these cards has what it takes to be your next upgrade...

Dig the look of these cards? Well, we bet you'll like their price tags even more. Generally speaking, overclocked models of video cards, or any PC component, usually command significantly higher prices due to their improved features and performance. But here, Asus has bucked that trend and set their entire DirectCU line at or close to the cost of stock cards. For example, re-badged reference design GTX 580s go for $499 online. The Asus DirectCU II GTX 580 also sells for the same price, but includes several enhanced features including higher clock speeds and and upgraded cooling solution. Let's take a closer look at these features and how well they perform in various benchmarks.

Closer Look: DirectCU and Super Alloy Power

How are these cards different from reference designs?
Some might glance over these products and wonder what the hook is. Any time a new series of graphics cards are launched by AMD or NVIDIA, it is common for add in board (AIB) partners to tweak various features so that consumers have even more attractive options to choose from, beyond the original reference design. Well, each one of the cards here has taken the basic blueprint from the GPU makers a step further. In addition to higher GPU speeds, they also provide improved cooling solutions. The heatsinks have been redesigned to provide improved cooling in order to handle the increased frequencies that are set for their graphics engines, while also reducing noise output.


 

 

What exactly does DirectCU have to offer?
With the all new DirectCU II, Asus claims plenty of improvements over the reference designs of these particular graphics cards. Before we get to the results, let's spell out advantages the card maker wants you to be aware of. Asus claims to improve heat dissipation by providing up to 600% more airflow and superior overclocking with their Voltage Tweak utility. In addition, the cards feature dust proof fans, GPU Guard, Fuse Protection. And they all sport "Super Alloy Power technology" which promises a 15% performance boost, up to 35°C cooler operating temps, and 2.5x longer lifespan. With that said, let's take a closer look at exactly how they implement all of these features.


Direct contact heat sinks have taken over the aftermarket CPU cooling scene. It only makes sense for video card makers to implement the same feature on their products. The exposed heat pipe format has become popular because there is no additional thermal resistance between the heat generated by the GPU and the copper heat pipes that transfer it throughout the heat sink. 

What does Super Alloy Power bring to the table?
In short, Super Alloy Power makes use of better components on the graphics card in order to increase performance. This is accomplished by reducing power loss, enhancing durability, and achieving cooler operation. SAP is implemented specifically in the chokes, capacitors, and MOSFETs found on every DirectCU product.


Their chokes consist a combination of unique alloy formula and a concrete core, eliminating the audible buzz sound heard from some video cards under load. Additionally, SAP capacitors allow for a 30% increase in maximum voltage, while lasting up to 2.5 time longer than the capacitors used in other graphics cards. The Super Alloy MOS also raises the voltage threshold, but is much smaller and operates cooler than generic MOSFETs. Also, a unique capacitor called SAP CAP is located back to back with the GPU in order to provide a cleaner power supply for more stable overclocking.

Yet another super feature we came across is called Super Hybrid Engine (SHE). It switches between high and low power profiles in real time, cranking up the power to the video card only when you need it.

The battle against dust rages on!
In addition to being larger than the fans you'll find on other graphics cards, ASUS DirectCU models feature dust proof fans. Asus says these fans are sealed twice over to prevent dust from entering the housing assembly and clogging up the bearings. The result is an increase in the life of the fans by up to 10,000 hours.

In the past, we've experienced fan malfunctions on a couple of very old video cards. Out of the latest crop of GPUs tested in the last couple of years, none exhibit any fan issues. This particular feature would take a long time to actually test (probably several years of constant use), but it's reassuring to know Asus has taken an extra step here.

Quick overview of the GTX 580
The GTX 580 is the fastest single GPU card on the market. Only the dual-GPU GTX 590 and HD 6990 video cards are faster. With that said, it's clear the GTX 580 sits at the high end of the spectrum, in both price and performance. They can be found online between $499 and $559.

How does the DirectCU II GTX 580 differ from the stock model?
The Asus DCII version of this card deviates from the reference design in quite a few ways. Asus has reconfigured the core clock speed, output ports, PCB, and cooling. This model operates at 782 MHz vs 772 MHz reference speed, while offering two DVI, one DisplayPort, and one HDMI port. The stock card provides only two DVI and one mini-HDMI port.

 




They also increased possible power consumption by requiring two 8-pin PCIe power supply connections. In addition, they installed a back plate heat spreader for additional component cooling. This also improves the appearance of the product while providing an added layer of physical protection.

One important category where the DirectCU II GTX 580 is similar to the stock model is cost. Re-badged reference design cards sell for $499 online, the same price tag found on this particular product.

 

Installation

Here we show the DCII GTX 580 on the Asus Rampage III motherboard. It definitely takes up a considerable amount of real estate, but there are still a total of four PCI expansion slots available and enough room for another triple slot GTX 580 for SLI action.

Quick overview of the GTX 570
After the GTX 580, the next card in NVIDIA's line up is the GTX 570. Although it costs significantly less than its big brother, the 570 offers a lot of performance. We've seen GTX 570 online from as low as $329, all the way up to $369 with factory overclocks at 800 MHz.

 

How does the DirectCU GTX 570 differ from the stock model?
Like the DCII GTX 580, Asus changed up the core clock speed, output ports, PCB, and cooling of the GTX 570. This card operates at 742 MHz vs 732 MHz stock, while offering two DVI, one DisplayPort, and one HDMI port. Again, the reference design provides only two DVI and one mini-HDMI port.

 





Once again, the power configuration has been tweaked. Where the stock 570 requires two 6-pin power connections, the DCII model needs an 8-pin and a 6-pin in order to operate. Also, this card sports a back plate for additional cooling.

 

Installation

Since this card is physically similar to the DCII GTX 580, it takes up the same amount of room on the motherboard. The image above shows how the card matches the length of the Rampage III, with the heat sink shroud extending past about half an inch. And as with the 580, there is enough room for another triple slot card.

Quick overview of the HD 6970
The HD 6970 is AMD's fastest single GPU card. It trails the GeForce GTX 580 in performance, but is competitive with the GTX 570. Nonetheless, it is definitely a potent card that can handle almost any game at maximum settings. Prices for the HD 6970 range from $339 to $389 for overlocked models.

How does the DirectCU II HD 6970 differ from the stock model?
Looking at the DCII HD 6970, we find several changes from reference design. First, the core clock speed is increased to 890 MHz from 880 MHz stock. Second, this card offers two DVI and four DisplayPorts. The reference design provides two DVI, two mini-DP, and one HDMI. And of course, the printed circuit board is redesigned with upgraded components, and has the DirectCU II cooling solution attached to it.

 




The stock 6970 requires one 8-pin and one 6-pin PCIe power connector, while the DCII version raises the bar by demanding two 8-pin connections. Interestingly, Asus decided to omit the additional back plate found on the DCII GTX 580 and 570 models.

Installation

In this view of the card, you can see the rear view of how the HD 6970 sits on the motherboard. Like the previous cards, the triple slot form factor does occupy a lot of room, and could possibly be an issue for users who utilize the majority of their expansion slots. Still, even with the HD 6970 installed, there's enough room left over for additional expansion cards like a sound card and PCIe-based storage drive.

Quick overview of the HD 6950
The HD 6950 falls in line right where you would expect it, behind the 6970 in performance and with a lower price. It's clearly slower than the GeForce GTX 570, but faster than the Radeon HD 5870. They can be found online in the $239 to $299 price range.

How does the DirectCU II HD 6950 differ from the stock model?
Like the other cards we've looked at, the DCII HD 6950 comes with a small GPU frequency increase, 810 MHz from 800 MHz stock. It offers two DVI and four DisplayPorts, much different from the options found on the reference design. Also, the cooling is completely upgraded with the DCII triple slot heat sink and dual fan system.

 





Looking at the power requirements, the DCII HD 6950 needs one 8-pin and one 6-pin connector. On the other hand, the reference design calls for two 6-pin PCIe plugs.

 

Installation

 

The image above depicts a side view of the HD 6950, as you would see it looking through a case window. It is deceiving though, as the card doesn't actually extend past the edge of the motherboard as much as the picture shows.

Quick overview of the HD 6870
The HD 6870 is an impressive mid-range card that provides a compelling solution for those who want the most bang for their buck. Current prices range from $204 for reference design models, all the way up to $269 for overclocked versions running at 940 MHz. At launch, we found it performs on par with the GeForce GTX 470, and a bit slower than the Radeon HD 5870. But it did bring a sense of refinement to AMD's lineup by lowering power consumption, better support for DX11, and enhanced CrossFire scaling.

How does the DirectCU HD 6870 differ from the stock model?
Like the other cards we've looked at, this model is outfitted with the Asus DirectCU cooling solution and mild factory overclock. Without a doubt, it's a good option for those who require a little extra from their PC components and want to stand out from the crowd. The difference include a core clock speed of 915 MHz vs 900 MHz, two DisplayPorts vs two mini-DisplayPorts, customized cooling, and a back plate. Also, the reference design offers an HDMI output, while this model does not.

 




But similar to the stock card, the DCII HD 6870 is a dual slot graphics card. It still requires only two 6-pin power connectors and continues to use a single fan.

Installation

Lastly, we see the HD 6870 making a home for itself on the Rampage III. It doesn't take up as much room as the other cards in this article, with only a dual slot form factor. It's worth noting, we've read several users have complained that two of these cards will not fit in adjacent PCIe slots due to the back plate. That's something to consider if you planned on a CrossFire setup with this particular product.

Test System and 3DMark

HOW WE CONFIGURED THE TEST SYSTEM: In order to provide comparable results, the graphics cards tested here were installed on the same, high end X58 based test system. The components we used consisted of an Asus Rampage III Extreme motherboard, Core i7 980X Extreme Edition processor, and 6GB of OCZ Blade memory. Within the BIOS, we configured the processor to an overclocked speed of 4.27GHz and memory to 1857MHz.

We feel these settings will minimize the occurrences of CPU performance bottlenecks during benchmark runs and allow the graphics cards to show their true potential. Furthermore, our Crucial M225 solid state drive entered the testing process with a clean copy of Windows 7 Professional 64-bit installed. Once installation was complete, we fully updated the OS and installed the latest drivers and applications relevant to the review article.

Futuremark 3DMark Vantage
Synthetic DX10 Performance


3DMark Vantage

Futuremark's synthetic 3D gaming benchmark, 3DMark Vantage, is specifically bound to Windows Vista-based systems because it uses some advanced visual technologies that are only available with DirectX 10. With this latest version of the benchmark, Futuremark has incorporated new graphics tests, CPU tests, several feature tests, and support for the latest PC hardware. We tested the graphics cards here with 3DMark Vantage's Extreme and Performance preset options.

We ran 3DMark Vantage just in case you wanted to see DX10 performance numbers. Here we see the GeForce cards with the edge over all three Radeons. But out of all the DirectCU cards in our stable, the GTX 580 reigns supreme.

Futuremark 3DMark11
Synthetic DirectX Gaming


3DMark11

The latest version of Futuremark's synthetic 3D gaming benchmark, 3DMark11, is specifically bound to Windows 7-based systems because it uses the advanced visual technologies that are only available with DirectX 11, which isn't available on previous versions of Windows.  3DMark11 isn't simply a port of 3DMark Vantage to DirectX 11, though.  With this latest version of the benchmark, Futuremark has incorporated four new graphics tests, a physics tests, and a new combined test.  We tested the graphics cards here with 3DMark11's Extreme and Performance preset options.

 

As Futuremark's successor to Vantage, the all new 3DMark11 works the latest generation of video cards differently than its predecessor. Once again, we find the GTX 580 in a comfortable lead but also observe the HD 6970 inching past the GTX 570 on the performance graph.

At the end of the day, you really can't do much with 3DMark besides running the test and compare your score with others on discussion forums. The following pages consist of our real world gaming tests, so let's find out how the Asus DirectCU graphics cards perform in that environment.

Alien vs Predator - DX11

 

Alien vs Predator
DX11 Gaming Performance


AvP

Alien vs Predator is a DX11 title from British developer Rebellion, the same team behind the 1999 original PC game. It brings the war between two of science fiction's most popular characters to the first person shooter gaming world. AvP delivers three single player campaigns and provides unique 3-way multiplayer gaming as well. For our testing, we used the AvP stand alone benchmark using a resolution of 2560 x 1600 and maximum image quality settings.





On the previous page, we saw the HD 6970 and GTX 570 switch places as the second fastest card behind the GTX 580. While it's obvious the 580 leads the pack, the only question our testing really answers is which DirectCU card takes the runner up spot. In Alien vs Predator, the HD 6970 was faster in all three resolutions and led the GTX 570 by 2 to 4 frames per second.

Civilization V - DX11

Civilization V

Civ 5

Sid Meier's Civ 5 is a turn based strategy game developed by Firaxis released in September 2010, and is the latest game in the Civilization series. You start off in prehistoric times and venture into the future on a procedurally generated map. A number of different victory conditions are achieved through research, expansion, economic development, government and military conquest. For our testing, we utilized the built in benchmark using multiple resolutions and maximum image quality settings.





In Civilization V, the rankings change up a bit. The GTX 570 takes full control of the second spot behind the powerful GTX 580. Trailing by only 5 FPS at 2560x1600, the HD 6970 gets blown away in the lower resolution tests.

Transparent
Dirt 2 - DX11

 Dirt 2
 DX11 Gaming Performance


Dirt 2

Dirt 2 was released in September 2009 and provides a sequel to the original Colin McRae: Dirt racing game. Codemasters delayed the PC version of Dirt 2 so that they could enhance their Ego engine with DirectX 11 effects. Dirt 2 is also a solid benchmark for multi-core processors since DX11 is designed to take advantage of multi-threaded system architectures.



In Dirt 2, we find the GeForce cards on top once again. Although the GTX 570 gets edged out the HD 6970 by only three FPS at 2560x1600, it pulled away during the other two tests.
 
Transparent
Far Cry 2 - DX10

 

FarCry 2
DX10 Gaming Performance


FarCry 2

Like the original, FarCry 2 is one of the more visually impressive games to be released on the PC. Courtesy of the Dunia game engine developed by Ubisoft, FarCry 2's game-play is enhanced by advanced environment physics, destructible terrain, high resolution textures, complex shaders, realistic dynamic lighting, and motion-captured animations. We benchmarked the graphics cards in this article with a fully patched version of FarCry 2, using a built-in demo run recorded in the Ranch Map. The test results shown here were run at multiple resolutions and maximum image settings.





Far Cry 2 is another game that favors NVIDIA. Much like the results from the previous page, the GTX 580 and 570 occupy the top two spots, followed by the trio of Radeons.

Transparent
Lost Planet 2 - DX11

 

 Lost Planet 2
 DX11 Gaming Performance


Lost Planet 2

Lost Planet 2 is a third person shooter developed by Capcom. It is the sequal to Lost Planet: Extreme Condition, and takes place ten years after the events of the first game. The plot begins with Mercenaries fighting against Jungle Pirates, while featuring major boss battles, extreme terrain, and the ability to pilot mechanized armor suits. We tested the game engine using the stand alone benchmark provided by Capcom, at 2560 x 1600, No AA, and high image settings.

Historically, we've noticed that Lost Planet 2 is a game that performs much better with NVIDIA hardware installed. That observation rings true once again. The GeForce cards annihilate the Radeons in all three resolutions tested. 

Transparent
Metro 2033 - DX11

 

Metro 2033
DirecX11 Gaming Performance


Metro 2033

Metro 2033 is your basic post-apocalyptic first person shooter game with a few rather unconventional twists. The game is loosely based on a novel by Russian Author Dmitry Glukhovsky. It boasts some of the best 3D visuals on the PC platform currently including a DX11 rendering mode that makes use of advanced depth of field effects and character model tessellation for increased realism. We tested multiple game resolutions and in-game image quality options set to High Quality mode, with DOF effects disabled.





Metro provides us with more competitive results. Of course, the GTX 580 is still the fastest, but the HD 6970 creeps back up to second place. It's very close though. The GTX 570 trailed by only 3 FPS at 2560x1600, 1 FPS at 1920x1080, and tied at 1680x1050 resolution.

S.T.A.L.K.E.R. Call of Pripyat - DX11

 

S. T. A. L. K. E. R. - Call of Pripyat
DX11 Gaming Performance


S.T.A.L.K.E.R.

Call of Pripyat is the third game in the STALKER series and throws in DX11 to the mix. This benchmark is based on one of the locations found within the latest game. Testing includes four stages and utilizes various weather conditions, as well as different time of day settings. It offers a number of presets and options, including multiple versions of DirectX, resolutions, antialiasing, etc. SunShafts represents the most graphically challenging stage available. We conducted our testing with DX11 enabled, multiple resolutions, and Ultra settings.





Our STALKER results mimic our previous gaming tests that give a serious advantage to GeForce cards. Both the GTX 580 and 570 led the comparison group in performance by a wide margin.
 
Transparent
Overclocking Performance
Overclocking is not an exact science. When it comes to overclocking headroom, every GPU is different. And just because your friend's GTX 580 hit 1000MHz doesn't mean that yours will, even using the same settings and hardware. Many factors can influence what a video card is capable of, starting with the unique capability of each GPU. These factors may also include complementary components within the system, but we find the primary influence is the type of cooling used on the graphics card.
 
Overclocking 
Push it to the limit

To overclock the DirectCU video cards, we used the Asus Smart Doctor utility. Here, we're showing the rated frequency of the cards in blue, and the overclocked speeds we reached in gold. Relatively speaking, the GTX 570 was the most impressive of the group, reaching 970 MHz from its rated speed of 742 MHz, a 31% boost. The GTX 580 increased by 28%, the HD 6950 by 25%, and the HD 6870 by 18%. Interestingly, the HD 6970 was only able to muster an 8% overclock.



We also overclocked the memory and got some pretty good results. The HD 6950 hit 1530 MHz, an increase of 22% over its rated frequency. It was followed by the GTX 570 with a 21% increase, and the 580 with a 20% bump. In addition, the HD 6870 was able to improve by 19%. Once again, the HD 6970 brings up the rear with a 19% overclock.
 

Transparent
Power Consumption and Temps
Before bringing this article to a close, we'd like to cover a few final data points--namely power consumption and temps. Throughout all of our benchmarking and testing, we monitored how much power our test system was consuming using a power meter. Our goal was to give you all an idea as to how much power each configuration used while idling and while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the graphics cards alone.
Power Consumption and Operating Temperatures
How low can you go?



The power consumption results shown fall in line with expectations. Under load, GTX 580 and 570 cards use the most juice, followed by the HD 6970 and 6950. Of course, the HD 6870 needed the least amount.




With fan control on auto, the results show the four cards sporting the dual fan DirectCU II cooler operate at similar temps in both idle and load states. But surprisingly, the GTX 580 displayed the lowest load temperature. Also, the HD 6870 and its single fan cooler ran warmer than the other models.

Transparent
Performance Summary and Conclusion
Performance Summary: Before running a single benchmark, we were fairly certain where these cards stood when compared to one another. The reference designs have been out for awhile now and these models basically provide a minimal boost straight out of the box. Out of the cards we tested, the pecking order plays out like so - GTX 580, GTX 570, HD 6970, HD 6950, HD 6870. The real benefits of cards like these are realized when you consider all of the other aspects that enthusiasts demand from their parts, such as good looks, upgraded cooling, and overclocking.


 

Traditionally, you've had to pay more for customized graphics cards that feature factory overclocks and redesigned cooling solutions. It's standard practice for companies to charge a premium for those particular models. But that's what makes the DirectCU line from Asus somewhat surprising. All the cards we tested provide more features than the stock models they are based on, while costing the same or charging a small premium. From a value perspective, it's tough to beat these offerings from Asus.



 

In closing, we feel Asus hit the ball out of the park with their DirectCU product line. It's clear that the company has listened to the community and provided a series of products that address the desires of those who use them. The cards are a winning combination of form and function that impress in almost every category. And by pricing them competitively, it's easy to make an argument for an Asus DirectCU model versus the competition.

Of course, the triple slot form factor is an issue for extreme users who utilize multiple expansion slots on their motherboards. But unless you fall in this category, there really is not much to complain about. The only other knock we have is the warranty length. Video card makers like EVGA, XFX, and Zotac offer lifetime warranties on some of their products. Asus currently offers a three year warranty, but registration is not required within a certain amount of time, as is the case with the lifetime warranties we mentioned. With that said, we are very pleased with the DirectCU line of video cards from Asus and highly recommend them to anyone on the market for a high performance graphics card.
