Наверное, нет ничего проще, чем выбрать на The computer market is an entry-level gaming graphics card. Indeed, for most buyers in this segment, the cost of a graphics accelerator is more important than performance. However, there are exceptions - when the manufacturer offers the user to purchase an inexpensive device that can surprise the future owner with worthy potential in work and games.
The focus of this article is an HD 6850 video adapter fromfamous American concern ATI. The reader is invited to get acquainted with the gaming solution closer: see the full review and learn the technical characteristics of an interesting device. Reviews of the owners and expert recommendations will help the beginner to make a choice in the market.
Elite representative
Oddly enough, the characteristics of the Radeon HD 6850they hint to a potential buyer that he is a representative of a game class, and not some kind of state employee. Indeed, according to the trends of the computer market, only powerful video adapters are equipped with high-speed 256-bit data transfer bus. It's no secret that the bandwidth of a video card is directly proportional to the frequency of the graphics core and the bus.
The second hint is the size of the PCB andcooling system. Only gaming platforms are equipped with a turbofan and a closed housing for proper distribution of cooled air. It remains only to understand the purpose for which the manufacturer has set a low price for such an interesting and attractive product.
Pledge of high performance
Review of the video card HIS Radeon HD 6850 is better to startfrom the technical characteristics, because it is thanks to them that the graphics accelerator is able to demonstrate high performance in gaming applications. The frequency of the graphics core Barts Pro is only 775 MHz. As for the memory, here the video card is also not a complete order, modern GDDR5 modules have too small a volume - 1024 MB. Apparently, it is this indicator and forced the manufacturer to place his product in the lower price segment of the game class.
About 1.7 installed on the device chipbillion transistors and 960 stream processors. Under the texture given 48 blocks (in the previous model, HD 5850, there were 72). It is worth noting that the chip itself is produced by a 40-nanometer technical process.
About technologies and software
Supported version of DirectX 11outdated, but most gaming applications created specifically for this set of libraries. And it is unlikely in the next few years the situation will change radically. In the HD 6850 video adapter, the graphics accelerator supports 3D visualization at the hardware level. This solution allows the user to connect to a computer TVs and monitors that support the output of a three-dimensional image on the screen.
Naturally, the manufacturer has equipped its product.and built-in processor for processing surround sound, as well as a special decoder that allows you to display the image in FullHD format. Only in the AMD Radeon HD 6850 graphics card they are confused about the characteristics of the energy saving system. The device, even when idle, consumes too much electricity and does not automatically go into power saving mode.
Features of the power system
Вообще, тематике энергопотребления стоит уделить more time. After all, the uninterrupted operation of the video card is a priority for each user who decided to find out in more detail the graphic accelerator Radeon HD 6850 characteristics. User reviews in the media are quite understandable and understandable - the game video adapter is not as simple as it seems.
The declared power consumption of the video card inThe factory version is 127 watts, but this parameter can almost doubled when overclocking the graphics core and memory bus. Most interestingly, the performance of the video adapter in overclocking shows an increase of only 20-25%. Yes, from the outside it looks really strange. With regard to the requirements for the power supply, it is better for the game lover not to save money here and provide the gaming platform with a powerful device (500 watts and above).
PCB package
Conducting an overview of components on the HD 6850I want to draw the user's attention to one interesting factor. The manufacturer AMD allowed himself to arrange the batteries around the perimeter of the printed circuit board, and not to take them into a separate unit, as is the case with the more expensive gaming video adapters. The graphics core is located in the middle of the board, the memory modules are spaced around the processor socket, and the chips and stabilizers are soldered near the video output board.
Externally, the HD 6850 circuit board does not inspire confidence,and it becomes quite clear to many users where such high power dissipation and strong heat are taken from the video card. It is logical to assume that many manufacturers representing AMD products on the world market will still be able to modify the power system and solve the problem of heating the video adapter.
Beautiful cooling system
Appeal and effectiveness are rarely mutualcomplement each other. Trying to make a beautiful product, most manufacturers of computer components simply distract a potential buyer from a more important detail. The same happened with the ATI Radeon HD 6850 video adapter, the characteristics of the cooling system of which the technologists decided to disguise at the factory.
Yes, many users can reallyshock. Hardly anyone will like the fact that under the beautiful plastic casing of the fan there is only one copper plate, which is intended only to remove heat from the graphics processor. This approach of the manufacturer to the consumer causes a lot of negativity, which can be found by examining feedback from potential buyers.
Leader of sales
World-renowned company HIS noticedan interesting product in the computer market and did everything possible to make performance characteristics more attractive under the logo of the AMD Radeon HD 6850 graphics accelerator.
Start better with the fact that in the global marketThere are several modifications of the same chip. All are equipped with the same PCB, but have different heat dissipation systems and appearance. Yes, the manufacturer managed to achieve greater efficiency in the operation of the device and reduce power dissipation.
As expected, the company's technologistscompletely altered the power supply system board. The power supply system was not only removed by a separate unit to the back of the printed circuit board, but also divided into additional phases. Also, the manufacturer replaced the electrolytic capacitors with solid-state elements and installed additional PWM controllers.
Icy air flow
Отечественный покупатель уже успел познакомиться with the product IceQ X Turbo HIS Radeon HD 6850, the characteristics of which allow the video adapter to legally sit in the initial game segment. A feature of this graphics accelerator is not high performance, but complete noiseless operation. The manufacturer managed to achieve such results thanks to a proprietary cooling system.
Huge aluminum radiator not only completelycloses the graphics core, memory modules and batteries; it, like a sarcophagus, rises up to the protective casing, hiding in itself a huge fan. The low-speed cooler with large blades runs almost silently, pumping a large amount of cold air onto the radiator.
As for the performance of the HD 6850, heretechnologists of the company managed to slightly improve performance. So, the graphics core in the normal mode is able to demonstrate 820 MHz, and the memory runs at 4400 MHz. But with the overclocking of the chip, things are bad, the processor is limited to 850 MHz. Blame the cooling system, which is calculated only for the basic characteristics of the device.
A serious player in the market
But the video card HIS Radeon HD 6850 Overlockerclearly claims to take a leadership position in the middle segment of the game class. At least, this product in many test laboratories is compared with the more expensive solutions competitor Nvidia. Again, a modified power management system on a printed circuit board and a decent cooling system allowed the graphics accelerator to get ahead.
Taking the psychological barrier graphicThe processor shows the user the frequency of 1122 MHz. But the manufacturer did not experiment with memory - 4500 MHz. It is worth noting that the Hynix modules are installed on the board (the photo of the original chip can be seen on the manufacturer’s website), which have a hardware memory frequency limit at this point, so the company's technologists do not recommend the owner to continue overclocking GDDR5 modules.
Separate cooling history
More productive and expensive HIS solutionRadeon HD 6850, the characteristics of which were discussed above, is equipped with a very interesting cooling system. The manufacturer obviously did not save on non-ferrous metals, so it is not surprising that copper became the prevailing material for the radiator. It is not necessary to explain that, in terms of thermal conductivity, red metal is much more efficient than aluminum, therefore, users will have no questions about cooling the platform.
Will delight the owner and power reserveinstalled fan. In their reviews, many users claim that the cooling system of the HIS video card has an excellent overclocking potential. Features Radeon HD 6850 increased by almost 10%. The graphics accelerator accelerates to 1,244 MHz without any problems and demonstrates stable operation. Only the noise of the fan on the board is slightly irritating.
Similar products from other manufacturers
HIS does not have a monopoly oncomputer market. Quite a lot of other manufacturers have paid attention to an interesting product. The Radeon HD 6850 graphics card, whose characteristics are directly proportional to the cooling efficiency, interested XFX, PowerColor, MSI, Gigabyte, Asus, and other equally well-known brands. However, no one was able to outperform HIS products in terms of overclocking performance and efficiency.
The secret is pretty simple - none of the representativesThe market did not understand the problem of the AMD printed circuit board and did not make any changes to the hardware. Therefore, installing a more powerful cooler did not bring victory for Asus and Gigabyte companies in Taiwan. But the potential was, given that the world-famous brands have equipped the graphics accelerator with proprietary cooling systems. Therefore, it does not impress users for similar video adapters based on the Radeon HD 6850 description of characteristics.
Finally
In the price category up to 6000 rubles is enoughThere are many interesting solutions that can cope with many toys, but experts recommend the buyer to pay attention to this video adapter. The fact is that he is one of the few representatives who can work on a 256-bit bus. Yes, and the supported technologies should not be forgotten, after all, DirectX 11 has a future.
Video card Radeon HD 6850, reviews of which aremore positive character in the media will be interesting to game lovers who wish to use resource-intensive applications at low and medium quality settings. This is the only thing you have to sacrifice to the buyer, who paid a small fee for an attractive video card in the computer market.
