Nvidia GeForce GTX 580
Saturday, 7 May 2011 10:00
Posted by _Blogger_
In early 2010 Nvidia released their GTX 400 series of graphics cards for the hardcore gamers out there. However, just six months later they released the Nvidia GeForce GTX 580, the first model in the 500 series and the new flagship graphics card for this outstanding company. Much like the 480, this model uses DirectX 11 and has a single GPU. Most of the primary features that affect the 3D rendering and speed were updated to meet today's standards and the reality is that the GTX 580 is one of the fastest and best-performing graphics cards on the market. Because of this it received our TopTenREVIEWS Gold Award for overall power and performance.
GPU/Interface:
Nvidia chose to stay with the single GPU for the GTX 580, which is by no means a bad choice; they have been making this type of video card for years and know exactly what they are doing. This is by far the most powerful single-GPU card on the market when it comes to overall power output and benchmark tests. If you compare this card to that of the older 480 model you will notice that the specs are slightly higher across the board and that the power needed to run the card is slightly less than most of the competition. The transistor count was upped ever so slightly from their previous model and still outnumbers that of any card on the market.
Video Memory:
When it comes to finding a graphics card that will be able to play any game at top performance it's important to look at the clocked memory and overall memory. The Nvidia GTX 580 has the highest clocked memory speed we've seen – 2004 MHz – which even outperforms any dual-GPU cards on the market today. You are going to love the 1.5GB of memory because this will ease the amount of RAM needed to render the intense graphics of games like "COD: Black Ops" and other graphics-intensive games.
The memory in this graphics card is GDDR5, which is the new standard for any card that wants to compete with other high-end gaming hardware. The memory bus width did not change from the 480 model and stayed at 384-bits, which should still do just fine compared to most graphics cards on the market today. An amazing 192.4 bandwidth was added which comes very close to dual-GPU cards.Display Interface:
The Nvidia GTX 580 is like most other graphics cards from Nvidia and simply offers the connections that are most common. In this case they offer dual-channel DVI, Mini-HDMI 1.3 and also support VGA. Dual-channel DVI is by far the most common connection type and pretty much makes up for the omission of an HDMI connection. This card has the type of connections that are in demand and not a lot of extra ones which can be nice if you don’t know a lot about graphics cards and want to install your own.
Supported API:
With the release of Windows 7 also came the very important DirectX 11 update to graphics cards. Nvidia's first card to offer this DX 11 was the 480, so it was no surprise to see their replacement model with the same technology. The reality is that both of these cards use Fermi architecture based on CUDA and also use DirectX 11 for superior tessellation, which has always been one of Nvidia's strongest areas and will most likely stay that way.
Rendering Technologies:
The Nvidia GTX 580 graphics card is the second series of models to use what Nvidia likes to call Fermi; this is basically what CUDA was but with greater potential. CUDA allowed for higher performance, a wider array of applications to run at once, full-spectrum computing and just about anything else in terms of computing power. Now take that and add in the capability to work with everything DirectX demands and you have the new and improved Fermi. This technology is designed to aid developers, allowing them to create even better games for all of us to enjoy.
One of the main areas that Nvidia focuses on with their graphics cards is tessellation. This technology basically allows complex, intricate images such as clothing, water and fire to render faster. Things that have a lot of moving parts such as hair or grass are much harder to render because there are thousands or even millions of objects that have to move according the wind or the movement of an object. Tessellation makes it possible for each blade of grass or flame in a fire to act like it would if you were to see it in real life. This technology is always improving and will always be a huge since games will continue to become more lifelike and even more detailed.The ability to run multiple screens at the same time is another thing that most gamers and game developers need. This graphics card only allows for three displays which is enough for most gamers out there but will fall short for those developing the games of the future.
Additional Features:
All Nvidia cards can support up to 3 GPUs at the same time and for the most part this is about all you would ever need for any system. The graphics card itself is cooled by a fan and is also cooled by the fans or liquid cooling system installed into your machine; the combination should have no problem keeping this card at a reasonable temperature. The card is quite thick at 4.4 inches high which will take up 2 slots of most mother boards; keep this in mind if you are planning on adding two cards to your system.
Summary:
When push comes to shove, the Nvidia GeForce GTX 580 is going to beat out just about every other graphics card. In terms of tessellation, there is no graphics card on the market that can outdo the GTX 580. We would love to see Nvidia add a dual-GPU card to their lineup, but we're more than confident that this card will impress any gamer out there. Now if you want to really destroy the competition you can link two 580s together with Nvidia's own SLI multi-GPU solution; that would outperform anything on the market without even breaking a cyber-sweat.
Pros: The updated memory clock speed and use of Fermi technology make this card exceptional.
Cons: It only has a single GPU.
The Verdict: The fastest single GPU on the market hands down.

ATI Radeon HD 5970 Review
08:54
Posted by _Blogger_
The flagship of the ATI Radeon 5000 series is the ATI Radeon HD 5970. This card is quite the performance beast. Many have benchmarked this card alongside other top performers and it reigns supreme. We rated this card higher than the others because of its overall superiority. Even with the recent release of Nvidia’s 500 series card, it has stood its ground. Nvidia may have another 500 series graphics card up their sleeve to challenge the 5970, but for now Radeon product has no equal which is why it recieved our TopTenREVIEWS Gold Award.
There are a total of 3200 stream processors in this card, which gives it an acceleration edge over the competition. With a setup like this, you have fill rates of 46.4GPs (gigapixels) and 116GTs (gigatexels or texture pixels) to help get your FPS (frames per second) up, giving you a smooth gaming and video rendering experience.
The 75x20mm fan draws the heat off the heat sink and pushes it out through the back of the card. The fan operates relatively quietly with a low 42 watt idle consumption rate. While gaming, the fan will pick up the pace and can use up to 294 watts, but even at full rotation, it doesn't put out any kind of intolerable jet-engine sounds. Some other cards have had issues with load noise while under a load, but that shouldn't be a big deal with the 5970.
Concealing the heat sink, fan and the rest of the graphics card is the recognizable Radeon HD 5870 design. AMD probably went with this setup because it helps protect the card very well. It is fairly similar to the housing that Nvidia has been using for a while now.
The 5970 is a beefy graphics card and requires a fair amount of energy. To power it, AMD added a 6-pin and 8-pin pair of PCI Express power connectors. Previous dual-GPU graphics cards have used the same setup. Dual 6-pin connectors have been the most common standard for single GPUs, but it seems the additional GPU requires a little more. It's important to know this so you make sure to get a compatible power supply.
GPU/Interface:
The Radeon HD 5970 is a dual core graphics card like Nvidia’s GTX 295. It’s a fairly new idea, but seems to be well received, and may even be the future for all graphics cards. You could out perform this card with a pair of 5870s or GTX 480s, but the cost is prohibitive.
Having a dual core graphics card essentially means that you have a CrossfireX (dual card) system, but in this case, like the GTX 295, it’s all in one card. With this one card, almost every attribute is doubled. A good example of this is the core clock speed, which is 725 x 2MHz, theoretically giving you 1450MHz. For this reason the 5970 has quite an impressive set of GPU and memory specs.There are a total of 3200 stream processors in this card, which gives it an acceleration edge over the competition.

Video Memory:
The 5970 has the latest in video memory, GDDR5. In the stock configuration, they run at an impressive frequency of 1.0GHz x 4, however, they are rated for 1.25GHz operation, which gives you room to overclock. The reason it is underclocked is because it is pushing the PCIe 300 watt limit already, sitting maxed at 294 watts.
There is a 2GB capacity on this card, which should ease your RAM usage and provide some extra speed. More and more, less RAM is necessary on the motherboard if you have a good graphics card. If that's the case, then it'll probably be more than gamers and video rendering employees who get the nice graphics cards like the Radeon HD 5970.Supported API:
Among The Radeon HD 5000 series graphics cards' best features is the presence of DirectX 11 support. With the release of Windows 7 came DirectX 11, and AMD jumped on board quickly. Until the recent release of the GTX 400 series, Nvidia didn't have anything to rival these cards. It's true that there isn't much in the way of content for DX 11 yet, but that still put the 5000 series ahead of the game and ready to move forward. Although the current Nvidia flagship, the GTX 480, doesn't have the power of the Radeon HD 5970, it still put them back in contention with the rest of the ATI graphics cards.
Rendering Technologies:
The ATI Radeon HD 5970 can support a maximum resolution of 2560 x 1600 on not one, but rather, three monitors. This ability is due to AMD's Eyefinity technology. Although the other 5000 series cards have the same technology available, the 5970 has real potential in this area. In fact, to really test the capacity of the 5970, it has been suggested that you'd have to run it on three 2560 x 1600 resolution monitors. That's some serious power. There are even some dual 5970 CrossFireX systems that can do far greater resolutions across 6 monitors. That's probably overkill for the average consumer, but it's fun knowing that you have that ability.
Additional Features:
This graphics card is really quite large, even when compared to other dual GPU cards. It is over 12 inches long, nearly 4 inches wide and about an inch and a half tall. The size obviously suggests some weight, and sitting at around 3.5 pounds, it's one of the heaviest graphics cards on the market.
Sitting on the GPUs is a large aluminum heat sink made up of 36 fins. It is roughly half the size of the card. The heat sink helps cool not only the GPUs but also the built-in memory. It's designed this way for efficiency, especially with the help of the highly heat-conductive copper plate on the bottom.The 75x20mm fan draws the heat off the heat sink and pushes it out through the back of the card. The fan operates relatively quietly with a low 42 watt idle consumption rate. While gaming, the fan will pick up the pace and can use up to 294 watts, but even at full rotation, it doesn't put out any kind of intolerable jet-engine sounds.

It's important to know this so you make sure to get a compatible power supply.
Summary:
Plain and simply the ATI Radeon HD 5970 is a monster in the world of graphics cards. Even paired against Nvidia's GTX 480 it still has a commanding performance edge. The competition between these two parties has a history. They are continuously fighting for that top spot even though it is mostly a niche product that only enthusiasts go after. The battle between these two manufacturers is ongoing but it seems that the tides have turned in favor of AMD for the time being.

Graphics Cards: What to Look For
Friday, 6 May 2011 08:52
Posted by _Blogger_
There is a lot to graphics cards, but we've managed to break them down and define the key aspects so you can find the one that works for you. They broke down into the following categories.
GPU/Interface
The graphics processing unit (GPU) is basically a second CPU but is designed to offload all the graphics rendering from the CPU and process it on the graphics card. Obviously, these are made to handle intense graphical workloads, which frees up your CPU to run all the other aspects of applications. What does that mean for you? Faster processing! The fastest processor on the market would bog down and overheat if it tried to process graphics in addition to everything else. The main thing you're looking for on the GPU is the clock speeds.

Video Memory
This criteria goes hand in hand with the GPU; you also want a fast clock speed. The amount of memory is also crucial because it is the GPU’s own RAM. Like your CPU needs RAM, the GPU needs its own video memory to reach higher speeds. Also, the larger the bus width and bandwidth, the more information can be processed simultaneously.

Like your CPU needs RAM, the GPU needs its own video memory to reach higher speeds. Also, the larger the bus width and bandwidth, the more information can be processed simultaneously.
Display Interface
These are the connections that the graphics card uses to connect to a monitor. DVI, HDMI and DisplayPort all support the higher resolutions, with dual channel DVI as the most common. It is important to match up these connections with the ones your monitor has. If your monitor doesn’t have the same connections then you have to get a converter cable which may result in lower resolutions.

It is important to match up these connections with the ones your monitor has. If your monitor doesn’t have the same connections then you have to get a converter cable which may result in lower resolutions.
Supported API
Application Programming Interface (API) is the interface that enables interaction with software. Software that wants to use the GPU has to be compatible with the API of the card. For example, if your card only supports DirectX 9 and you buy a game or application that requires DirectX 11, you will have to upgrade your card in order to run it.

Rendering Technologies
This criterion refers to the various technologies that are integrated in to the graphics cards. It’s hard to say which ones are better than others, because opinion-based prejudice runs rampant when it comes to graphics cards and which is the best. Truth be told, they’re all very similar and do basically the same things. Also, unless a game or application is built specifically with some of the technologies, they often don’t make a great deal of difference. Others do make a difference, however. Nvidia is known for their CUDA technology and it has been a thorn in the side of ATI for a while now. On the other end, ATI’s new Eyefinity technology looks pretty impressive when you stretch your desktop across 6 screens and maintain HD quality.

Additional Features
These are just a few extra goodies that aren’t extremely important and actually vary depending on the board manufacturer (ASUS, EVGA, Sapphire, etc). The information on our site is from the base models of each manufacturer. Typically, board manufacturers will have additional versions with multiple fans, liquid cooling and other variations.
If you put all of these things together, you get phenomenal graphics cards such as the ATI Radeon 5970, GeForce GTX 580 and GeForce GTX 480. Unfortunately most cards excel in one or two areas and fall short in another so there isn’t really a perfect one. We'll help you find the one that meets your expectations and fits in your budget. The better the card, the more it’ll cost, but the results can be well worth it.These are just a few extra goodies that aren’t extremely important and actually vary depending on the board manufacturer (ASUS, EVGA, Sapphire, etc).
