Specialist graphics cards with AMD graphics processors HIS 7850 IceQ presents the X Turbo X 2GB, a display device designed for gamers who want to enjoy the latest titles without having to undergo any jerk while taking advantage of the latest technologies in current matter.

HIS IceQ X 7850 the Turbo X 2GB shows the outline of the HIS IceQ X 7870 knowing a great success thanks to superior performance while controlling the heat release due to one of the best cooling systems currently on the market very quiet: the IceQ X. As usual and with good reason, the  Dell Latitude E6500  brand boosts performance by increasing default frequency of the GPU to achieve those of the HIS 7870. More electronic components are capacitors with quality and SOC of solid floors and digital power more stable, more efficient and more particularly reactive. Thus, thanks to its 2.8 billion transistors and its 2GB of RAM, HIS IceQ X Turbo X 7850 2GB should have no trouble be among the graphics performance compared to prices more attractive. HIS IceQ 7850 then X Turbo X 2GB worthy contender for the HIS 7870 in the same range?

AMD Radeon HD7800 aka Southern Islands

So what GPU innovates with a fine engraving of 28nm allowing it to contain 2.8 billion transistors. It supports Eyefinity technology real benchmark for managing multiple screens, the latest version of DirectX 11.1 API with Microsoft graphics in games always more detailed and impressive. Always with the aim of enhancing computing power, the PCI Express 3.0 is supported thereby doubling the  Dell Inspiron 1526 battery band width available on this interface. The founder deploys AMD ZeroCore, another technology dedicated to power management to reduce power consumption intensive yesterday.

The  Dell Inspiron 6000 battery map shows relatively compact dimensions with a length of 23.5cm. His aesthetic is attractive although flashy with a PCB turquoise, a fan with pale blue translucent and its decoration silver honeycomb. HIS IceQ X 7850 the Turbo X 2GB requires only six auxiliary power connector pinsa connect directly to the power of the machine. It has solid components 'High Quality' improving the stability of performance, but also preserves the potential damage to components at low cost. The supply phases are fitted to the card type and digital providing dynamic overclocking potential while higher while keeping power consumption.

Cooling system

HIS IceQ 7850 however the X Turbo X 2GB cooling system has the most elaborate brand or model IceQ X specifications enticing. HIS promises a lower temperature of 17 ¡ã C against the reference cooler with the fan with a diameter of 9.2cm in diameter and the lifetime is guaranteed for 50,000 hours. This is the same as  HP 484170-001 battery fitted version Radeon 7870. Its beautiful radiator is equipped with an aluminum base whose heart is copper. To deport the heat, two heatpipes are embellished with aluminum fins. HIS therefore indicates 28dB of noise in office use is 3dB lower than the reference cooling system proposed by the founder.

Performance Hard Reset

Our latest title is the latest we test: We include Dell Latitude E6510  Hard Reset years since our tests has the distinction of being optimized computing power required for anti aliasing and tessellation. For each of our three resolutions used, we find our details now classic levels: low, intermediate and high. On this basis, we disable anti aliasing as low tessellation mode, we set the anti aliasing x4 and tessellation normal mode through and finally, we push all options to their maximum for the test as demanding.

 

Overclocking

Overclock 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  Dell Latitude e6400 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.

Temperatures and noise

As a first step, we analyze the temperature to highlight the performance of each cooling system. In a second step, we compare the  Dell Latitude d630 battery speed of cooling fans used to keep the temperatures measured maps of our test. To seek to maximize the GPU, we use the software we choose Furmark and GPU-Z to monitor temperatures and fan speeds. Everything is going well for HIS IceQ X Turbo X 78500 2GB which heats a little less than 7870 because it is in all cases below 60 ¡ã C against 70 ¡ã C for the previous model. We appreciate then default speed to stay very close to 50 ¡ã C because it is the only overclockanf manually as we approach the 60 ¡ã C. But at the expense of a higher fan speed?

Consumption

HIS IceQ X to 78,500 X Turbo 2GB is constantly below 150 Watts when fully loaded frequency factory when our lives with Intel I7 2600K non overclocked. These are measurements taken at the  Dell Vostro 1520 battery outlet of our PC. At rest the card has an excellent command of consumption by being economical with only 74 Watts. It is 50 watts less load than 7870 and less than 10 watts at rest.

Conclusion

And although the level of computing power is the most convincing, players will not be bothered by excessive noise. Indeed, the HIS IceQ X Turbo X 7850 2GB has proved perfectly discreet with a cooling system more efficient, probably the best in the market today. By itself, it remains a fundamental choice argument to consider this card carefully. We have also enjoyed a really low power consumption because with only 150 watts meter test platform for our full activity, there are few competitors to do as well. Available within two hundred euros, the  Dell XPS M1530   price is certainly slightly higher than the reference models but has HIS 7850 IceQ with X Turbo X 2GB a quality much higher.
