Officially launched yesterday at CES, the GTX is nVidia's latest top-end graphics card and, as that preamble will have suggested to you. If you'll remember from our earlier article on the hardware, the GTX is a dual GPU card that features two chips that combine aspects of the.

The normal GTX had been produced using a 65nm process, but the chips used in the GTX use a smaller 55nm process. This seemingly small reduction has a large cumulative affect on the overall power and heat output of the chip, enabling nVidia to fit the same computing power in a smaller thermal envelope than would otherwise be possible.
Well, actually, toasty might be a better word to describe it as, despite the manufacturing and clock speed changes nVidia has made, this is still one hot card. No hotter than most other high-end cards, mind, just very, very hot so watch your fingers!
Air is sucked in from holes on both sides of the cards and ducted through a series of angled fins that run up the middle of the card. Half of these lead to a gap that runs along the top of the card while the other half are directed towards a set of holes on the second expansion bay plate.
This design does raise the age old concern of heat being pumped back into the case rather than straight out the back, which can lead to overheating. Asus also includes a code that you can use to save yourself 10 per cent on a selection of games, the full details of which you can find on the nZone website. The last little extra you get with this particular card is a neat little leather 12 disc CD wallet. All our testing uses a variety of manual run throughs and automated timedemos, but regardless of which test method is used, we monitor all tests to ensure performance is consistent.
Where there are spurious results or dips in performance we will note this. We also do multiple run throughs then take the average of these and report that figure to you. The test setup is as follows:. With masses of dynamic foliage, rolling mountain ranges, bright blue seas, and big explosions, this game has all the eye-candy you could wish for and then some. We test using the bit version of the game patched to version 1.
Surprisingly, considering its claustrophobic setting and graphically rich environment, we find that any frame rate above 30fps is about sufficient to play this game. All in-game settings are set to high for our test runs and we test with both 0xAA and 4xAA. Transparency anti-aliasing is also manually turned on through the driver, though this is obviously only enabled when normal AA is being used in-game. As a player you get to choose from an enormous range of character types and playing styles, as well as a whole host of vehicles.
Battles can span vast areas of open space and involve a huge number of participants. We test using the bit version of the game, which is patched to version 1. We use a custom timedemo from the Valley level, which we feel is about as graphically intensive as the game gets. We feel a framerate of at least 50fps is required for this game as the intense multiplayer action and high speed mouse movement demands it. Call of Duty 4 has to be one of our favourite games of last year. It was just eight hours of pure adrenaline rush that constantly kept you on edge.

The human hearing system has different sensitivities at different frequencies. This means that the perception of noise is not at all equal at every frequency. Noise with significant measured levels in dB at high or low frequencies will not be as annoying as it would be when its energy is concentrated in the middle frequencies.
In other words, the measured noise levels in dB will not reflect the actual human perception of the loudness of the noise. That's why we measure the dBA level. A specific circuit is added to the sound level meter to correct its reading in regard to this concept. This reading is the noise level in dBA. The letter A is added to indicate the correction that was made in the measurement. Frequencies below 1kHz and above 6kHz are attenuated, where as frequencies between 1kHz and 6kHz are amplified by the A weighting.
We test all cards on dBA levels. Obviously the reference coolers all perform roughly the same. The customized coolers are either louder or softer depending on what they try to achieve. We measured at a room temperature of 21 degrees Celsius. Now a couple of things are interesting here. First off you should see the P-states we discussed earlier, normally these will save you energy.
Pretty normal. But also remains fine within designed operational specifications. Last thing I wanted to show you, look at the beginning of the chart and see how well the GTX is clocking down to preserve energy. Tweet Setting up the PC Installing the card into your system will be a fairly easy job.
Power Consumption We'll now show you some tests we have done on overall power consumption of the PC. That power supply needs to have in total accumulated at least 50 Amps available on the 12 volts rails. You need a Watt power supply unit if you use it in a high-end system. That power supply needs to have in total accumulated at least 70 Amps available on the 12 volts rails. So in IDLE mode, you will not hear the card. We measure dBA coming from the PC. Gaming with an average title not stressing the GPU too much we can hear the fan a little, we measure roughly 44 dBA.
When we loop 3DMark Vantage for a while the GPU really heats up, as a side-effect the fan RPM will go up even higher, the noise-levels are now dBA which definitely can be heard, overall these results are a tad noisy. The core temperature Let's have a look at the temperatures this huge cooler offers. Though air will be exhausted outside the PC, always make sure you PC chassis is well ventilated. The new flagship was fitted with faster memory, a boost frequency of MHz, more shaders, and a TGP passing Watts.
This review ben The flagship series now has quicker memory, more shaders, and a TGP of Watts. Here are the specs:. Although we don't have any in house yet, this new card was announced on the 8th and will be available for purchase on the 15th of January The clock speeds compare as follows:. For this article will focus heavily on the performance of the GeForce GTX , as we've already covered the basic architecture and specifications.
We will recap them and cover the card itself on the next page, but for more detail see our initial article on the subject. Post Your Comment Please log in or sign up to comment. I recently considered buying a x2, until I heard about the , which I will be purchasing soon. The article was a bore, as I currently own a g80 ultra, and still regret paying the usd for it a year and a half ago. This is two 's slapped together, we all know that, yes its the best card currently.
Is it worth the money? Probably not if you have bills to pay and have fears of feeding yourself afterwards. To each his own though.
