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
Appeared in December 2011, the new generation of AMD Radeon HD 7000 GPU knows a great success thanks to excellent performance and support for the latest technologies in graphics cards. Segmented into three categories, this range of graphics chips wins in simplicity because there are the usual entry-called 7700 followed the series through 7800 and 7900 models come who held the top rankings all brands for a few months just before the arrival of Nvidia Keepler challenger. AMD Radeon HD7870 GPU powering our test card benefits from the latest innovations in terms of benefits. Before this entire graphics chip is among the first to see its frequency surpass the legendary GHz with architecture GCN (Graphics Core Next) and AMD PowerTune technology.
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.
Finally found the support CrossfireX to combine multiple graphics cards in a single machine but also the 4K video with its video outputs meet standards HBR2 DisplayPort 1.2.
HIS IceQ X 7850 presentation Turbo X 2GB
HIS now fifteen models of different graphics cards in the Radeon 7800 class shipping 1 or 2 GB of GDDR5 but nine of which are equipped with version 7850 settlors of a cooling system more or less elaborate and clock frequencies journals up. Others have a GPU AMD Radeon 7870. Economic models simply a cooling system or reference type IceQ but differ with frequencies between 1000 and 1100MHz for the GPU while those of the RAM do not change. The latest models are equipped with IceQ X cooling system quieter but also more efficient. The Dell Inspiron 1300 battery standard version is clocked at 1000MHz for the GPU; 100MHz wins through to reach and frequency of 1100MHz RAM to 1200MHz rest. The highest card knows a swift increase in RAM speed also with a gain of either 5000MHz or 1250MHz 50MHz workforce.
Our test model is HIS IceQ X Turbo X 7850 with 2GB AMD Radeon 7850 GPU clocked at 1000MHz and engraved in 28nm. Are present at his side 2048MB GDDR5 RAM format on a 256-bit bus clocked at 1250MHz. It has four video outputs, two standard mini displayport, one DVI and the last one HDMI. The side of the bundle, we regret that always marks neglect this aspect of the product for only a CrossfireX bridge and an HDMI adapter are attached to a CD-ROM containing drivers exceeded. Merme if there is a card holder limit unnecessary in view of the rigidity of the card, which will be the first to (re) offer games taking advantage of the card instead of remaining coupons downloads too often unanswered by AMD and DisplayPort adapters are really useful?
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 ° 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.
The fan-cooling the assembly is of a diameter of 9.5cm. Its blades are processed to obtain a geometry effective improving performance while maintaining quiet operation significantly. In addition it is equipped with PWM technology to enable it to adapt its speed according to the heat release. 800 rotations per minute at rest, it will be able to reach its maximum 3400 RPM.
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.
In Hard Reset, the rankings change and this time more successful as the Radeon 7870 GPU but also to Nvidia.
Even balance in 1680.
And finally by 1920 pixels, the HIS IceQ X Turbo X 7850 2GB incorporates enough power to meet all needs because it exceeds 50 FPS here.
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.
Due to a strong GPU overclocked by the manufacturer at 1GHz instead of 860MHz AMD préconnisés, it is considered normal to not be able to climb much higher. In addition, the voltage of the HIS IceQ X Turbo X 7850 2GB can not be modified by software including Ice Turbo HIS. We still managed to reach 1100MHz. It is still 28% higher than the reference frequency. For cons, the memory can make a leap forward as default 1250MHz; it is able to pass 1500MHz, ie an increase of 20%. Metro in 2033, overclock the HIS IceQ X Turbo X 78500 2GB saves 2fps high resolution and all options enabled. 3DMark 2011 shows interest to overclock the HIS IceQ X Turbo X 78500 2GB since 7000 may far exceed the low points in detail at a resolution of 1280x1024 pixels. High resolution and high detail, we crossed the 1700 points with 100MHz increase.
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 ° C against 70 ° C for the previous model. We appreciate then default speed to stay very close to 50 ° C because it is the only overclockanf manually as we approach the 60 ° C. But at the expense of a higher fan speed?
Now for measuring the operating speed of the fans of the HIS 7850 IceQ Turbo X 2GB. We can see that the radiator of the HIS IceQ X Turbo X 78500 2GB is particularly efficient because the fan does not need to run at its top speed to dissipate heat. Remains below 40% even without overclocking and under the additional 45% once the increased frequency manually. While many powerful graphics cards such as the HIS IceQ X 7870 2GB synonymous with high noise, we congratulate HIS offer a product as discreet. In fact, the card just above the operating 36.5dB which is excellent and very discreet. It will therefore be necessary before any conscious users maintain a quiet environment.
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
Success Continues HIS 7850 IceQ with X Turbo X 2GB card as proved most convincing on many points. Around the owner allowed us to discover a good quality card with quality design and manufacture some. We are dealing here with selected components more stable and more efficient more conducive to overclocking. The performance side, the HIS IceQ X Turbo X 7850 2GB has no problem to match in some cases exceed see a Radeon 7870 core. It is perfectly tailored for the most demanding games and even in the highest resolutions with a level of detail and maximum filtering.
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.
This involves thank Nvidia have launched its GTX 650Ti with which AMD reacts immediately by reviewing its prices downwards. This is why the HIS IceQ X Turbo X 7850 2GB we recommend is a card of choice and with probably one of the best price performance to date.
