Gigabyte told us his card catalog of the most powerful Nvidia graphics chip embedding a: GV-N680OC-the 2GD with the famous GTX-680 GPU and 2GB of RAM.
With the suffix "CB", the card has a therefore factory overclocking and cool hunks of such computing power, Gigabyte covers her famous chip cooling technology using the "Triangle Cool" supported by Windforce.
So the brand offers a Dell Studio 1558 designated for the most demanding players all electronic components including quality stamped "Ultra Durable" and provides compatibility with the famous technologies SLI, Physx, CUDA and 3D Vision.
With a fine engraving of 28nm and support PCI-Express 3.0, GV N680OC-2GD-is adorned for the latest games increasingly intensive computing power.
But she will do much better than the GTX-670 already ultra efficient and widely recommended?
The additional overhead caused Will it interesting and finally seize Does the gold medal for best FPS of all categories?
Gigabyte GV-N680OC presentation-2GD
Gigabyte continues to seduce us with its most powerful graphics processor with Nvidia's founder: the GTX-680. GV-N680OC-the 2GD therefore uses a non-standard GPU which features impressive.
Being part of the family "Keller", the GTX-680 also called GK104 welcomes 3.540 billion transistors; it is a bit less than the Radeon 7970 embarking 4.3 billion transistors both engraved in 28nm.
So the GTX-680 has 1536 sharers clocked at 1072MHz is a slight increase 66MHz.
These frequencies are nominal values ??which can now be overcome with Latitude E4310 Turbo Boost Technology as the turbo mode for our processors.
GV-N680OC-the 2GD can reach 1137MHz if conditions allow that TDP does not exceed 100% and temperatures are not too high.
Alongside GK104, take place 2GB GDDR5 RAM standard, operating at 1502MHz and uses a 256-bit bus while the Radeon HD7970 she uses 384-bit bus.
Gigabyte not only the benefits of NVIDIA GPUs as the brand adds a number of amenities to enhance the capabilities of the card, but also its reliability.
Firstly, the GV-N680OC-2GD uses high quality components using technology "Ultra Durable" and enabling significant gains on both the performance of these but underuse lifetime.
Gigabyte promises moderate temperatures of 5 to 10% compared to conventional components and also overclocking capabilities tenfold estimated over a range between 10 and 30%. Improvements of the same order of magnitude are also guaranteed the stability of the energy consumption.
After visiting the main technical characteristics of the GTX-680, GV-N680OC discover the-2GD whose lines are as convincing as the Radeon HD 7970 from the same brand. Above, three fans dominate a massive radiator powerful application and enjoy a lovely glossy black trim but plastic.
The GTX-680 has good looks all the more if it exceeds in length with many maps 27.5cm; she meets a height of two PCI slots.
On its front, there are two DVI and a DVI and Display Port. GV-N680OC-the 2GD is trimmed to manage multiple screens simultaneously and without adapters. Vents are also present to help dissipate the heat generated by the graphics processor.
At the rear of the GV-N680OC-2GD is representative of the turquoise Gigabyte is selected for its PCB. A metal brace stiffens the whole and avoids generating excessive stresses on the PCI-Express 16X motherboard.
We also note that the cooling system is slightly above the map.
Auxiliary power connectors allowing six to eight contacts to GV-N680OC-2GD benefit from additional maximum power of 225 watts plus 75 watts authorized by the PCI-Express for a total of 300 watts.
By removing the Wind force, we discover Gigabyte quality through careful design and near perfect card. The components are aligned and arranged inveiglement.
We note especially that the MOSFETs are welded in the longitudinal direction, not vertically as we used to see. Their cooling is entrusted to an especially dedicated radiator.
We focus now on the cooling system of the GV-N680OC-2GD Wind force called.
It uses three slim fans with a diameter of 10cm compatible with PWM technology enabling them to adjust their speed according to the temperature of the assembly.
The radiator will not leave indifferent aficionados cooling systems with HP G4 Battery its beautiful finishes and massive heat pipes on which are many finned divided into two massive blocks.
Heat pipes are not just crossing a block covering the GPU as is frequently the case for our GV N680OC-2GD-they spend directly on the graphics chip copper thus improving the dissipation and thus allowing to keep temperatures including at low stress.
GV-N680OC-the 2GD thus enjoys the same cooling system used by the GTX-670 from Gigabyte that we tested here and who knew how much we convince its many qualities and high performance.
3DMark 2011 performance
We begin our series of benchmarks with the most popular of them: Future mark 3DMark 2011 to obtain an excellent indicator for the performance of our graphics cards.
We use a resolution three levels of detail:
Bottom: MSAA 1, 1 and the anisotropy tessellation 1.
Intermediate: MSAA to 4, 5 and the anisotropy tessellation to 10
High: MSAA to 8, 16 and anisotropy tessellation to 15
And yes the GV N680OC-2GD-to offer the best score in 3Dmark 2011 significantly exceeded the 5500 GTX-670 could not reach low resolution even if it is only 300 dots with additional
In 1680 pixels, GV-N680OC-The 2GD gently approaching 4000 points while the Radeon HD 7970 is limited to a little over 3000 points when the level of detail is higher.
In 1920 pixels, GV N680OC-2GD-brushes impressive score of 3000 points almost double Radeon Latitude E5420 batteries a factory over clocked.
Performance Alien vs. Predator
We are now in the thick of things as we move to action games Alien vs. Predator provides an excellent overview of moderately demanding games.
Our benchmark series begins with a resolution of 1280x1024 and 1680x1050 and finally 1920x1080 pixels.
For each resolution, we use three types of settings:
Low: Anti aliasing x1, low level of detail, texture quality 0, shadow quality to 0 and the anisotropy 0. Ambient occlusion as tessellation and Advanced Shadow Sampling is disabled.
Average level: Anti aliasing 2, medium level of detail, texture quality 1, 2 quality shadows and anisotropic to 8. Tessellation, the shadow sampling and occlusions are still disabled.
High: all options are maximally activated and are anti aliasing x4, level of detail high texture quality 3, quality shadows 3, the anisotropy in x16 and the last three options enabled.
Now to practice tests and AVP has the particularity to prefer GPU AMD Radeon 7970 leaves in first place with 12 FPS more than our GV N680OC-2GD-in high detail to low resolution.
In 1680 pixels, the Dell E6220 maintains its big lead with more than 10 FPS still ahead. GV-N680OC-the 2GD still provides an excellent average of 64 FPS in detail levels. We note that without filtering, it remains above 200 FPS.
In 1920 pixels, the podium is unchanged with the Radeon 7970 in mind. GV-N680OC the-2GD Gigabyte is the second and did a bit better than its little sister the GTX-670.
Over clock a graphics card unfortunately does not multiply as much performance as processors of our PC. If for these gains can be significant and in many cases earn fifty percent performance easily GPUs rarely exceed ten percent.
To achieve the maximum frequency of the map, we start by increasing the speed of the GPU and when we reached its limit, we do the same with the memory. Once we have validated their optimal frequencies, we add the two values ??and GPU RAM so we ensure the stability test with 3DMark 2011 and another in 2033 with Metro to see the gains.
The cooling system is not changed and the fan speed is set to auto mode. We also make sure not to exceed the temperature is too high so dangerous to the life of components.
As we have seen in all our tests on the new generation of GPU Nvidia "Kepler", these graphics cards optimize their performance with GPU Boost technology to exceed the nominal frequency used.
And GV-N680OC-2GD is able to achieve without overlock frequency 1137MHz instead of 1072MHz core 66MHz or more.
However, we can go a little further because the HP Pavilion DV4 span> our test has remained stable with a gain of 100MHz is the final frequency 1172MHz.
The 2GB of RAM will collect them extra 200MHz to reach 1700MHz instead of 1500MHz real basic.
By paying attention to the TDP of the GV-N680OC-2GD, we note that is far from its maximum value because we do occasionally exceed 70%. This allows us to conclude that the Gigabyte GTX 680 does not need a high energetic consumption to reach its maximum capacity but on the other hand, some users may feel frustrated at not being able to go further as the PNY GTX 670 8 XLR able to exceed its maximum TDP.
In 3DMark 2011, it then easily exceeds 3200 points in high resolution and is not very far from the 15,000 point 1280 pixels.
Environmental practice using Metro 2033, GV-N680OC-the 2GD close to 50 FPS with high resolution and all filtering enabled.
Temperatures and noise
Through a session of Fur mark benchmark, let us express the GPU GV-N680OC-2GD us in order to capture all of its computing resources.
GV-N680OC-the 2GD reach 70 ° C which is much more tolerable even during long loads. But the three fans Wind force will they work quickly to reach this temperature level and therefore generate a lot of noise?
Fortunately for our ears but also to keep the GV-N680OC-2GD within acceptable temperatures, fans did not exceed 50% of their maximum speed, a behavior very similar to the Gigabyte GTX-670. We can infer that the radiator provides capabilities dissipation high-flying and this lack of difference is explained by the same characteristics both GPU distinguished solely on their clock.
Finally we measure the noise emitted by the E6500 battery one meter. At 25% of maximum speed fans, the card is completely silent with only 34.8dB. Its noise increase rapidly measuring almost 50% since 40dB, a value high enough but widely tolerated. Because at this level even if the GV-N680OC-2GD is heard, the noise is bearable.
Fortunately beyond the Gigabyte GTX 680 does not reach these high speeds very noisy because it may exceed 50dB.
Again like the GTX 670 GV-N680OC-the 2GD is economical in terms of power consumption.
With 80 watts in office use including our full test platform, we are on average common to all current graphics solutions.
In seeking to map its nominal frequency, our PC was less than 250 watts and once over clocked, we stayed far from 300 watts with "only" 254 watts.
How not to fall for the GV-N680OC-2GD design succeeds in its modern aesthetics and design quality? More Gigabyte has accustomed us to improve component quality performance while being efficient.
Like Vostro 1520 products benefiting from the cooling system exclusive to the brand called Wind force, GV N680OC-2GD-control well its thermal dissipation while maintaining a moderate level especially for the performance offered.
From the point of view of the results in our measurements, the GV-N680OC waiting-2GD above the Radon HD 7970 in all uses cases. However, the latter has proved it faster on different titles, although in Hard Reset for example, it shows impressive results.
Then the GV-N680OC-2GD she offers a report performance good price for the five hundred Euros it requires? One is tempted to say yes, but only in cases where the very good performance of the GTX-670 would not be enough even if they are available from three hundred and sixty Euros. One hundred and forty Euros difference between these two models is needed?
The choice will therefore depend on the available budget according to each waiting for the test of the MSI GTX 680 Lightning-published soon on our website.
