"South Islands"

First, a little about AMD's labeling of its latest products. The manufacturer has divided them into three levels according to performance. The codename "Cape Verde" refers to the Radeon HD 7700. The name "Pitcairn" hides today's contestants Radeon testing HD 7870 and HD 7850. High-performance products are called "Tahiti" or Radeon HD 7900. This is shown more clearly below.

  • Entry Level = Cape Verde = Radeon HD 7700 Series;
  • Mainstream = Pitcairn = Radeon HD 7800 Series;
  • High Performance Products = Tahiti = Radeon HD 7900 Series.

That is, on this moment AMD has covered all market segments with their 28nm graphics chips. Only the release of a dual-core video card based on Tahiti chips is expected. The tentative name is Radeon HD 7990.

Features of the AMD Radeon HD 7800 Series

The graphics processor Radeon HD 7800 (Pitcairn) has about 2.8 billion transistors and the Graphic Core Next microarchitecture. As mentioned above, the Radeon HD 7850 (Pitcairn Pro) chip has 16 computing units, and its maximum TDP is 130 watts. For the Radeon HD 7870 (Pitcairn XT), these figures are 20 and 175, respectively.

The slide below shows the main specifications of the Radeon HD 7850 and HD 7870 video cards

2GB GDDR5 memory is already becoming the standard for most mid to high end models. Thanks to 256-bit. bus and a high clock frequency of 1200 MHz (4800 MHz effective), the bandwidth is 154 GB / s. This will have a positive effect on performance when playing games with high resolution and picture quality.

Interface PCI Express 3

In the second half of 2011, almost all motherboard manufacturers presented their motherboard models with the 3rd generation PCI Express interface. With the release of the Radeon HD 7000 series, video cards with this interface appeared. PCI Express 3 has twice the bandwidth (32 Gb / s) than the previous generation PCI Express. Has doubled compared to PCIe 2 throughput on each line from 500 Mb / s to 1 Gb / s.

Naturally, to take advantage of the new PCIe 3, you need not only a video card and a motherboard with this interface, but also support from the processor (from the Ivy Bridge family, not all models will support PCIe 3).

Eyefinity 2.0

AMD has gone further with its Eyefinity technology, which is designed to display images across multiple monitors. Due to the high computing power HD 7000 series and support for Eyefinity 2.0, now you can display an image with a total resolution of 16000 x 16000 on multiple monitors. This allows you to display an image on 5 displays with a resolution of 2560x1600 installed in landscape orientation... To work with such resolutions, the older models of the family are equipped with a record 3 GB GDDR5 (HD 7970 and HD 7950).

V AMD drivers Catalyst, starting in February, will support custom resolution. This means you will be able to set the required resolution depending on the configuration of the displays in Eyefinity. As of Catalyst 12.2, there is an option to install the Start menu on a display that is convenient for you, and not on the far left, as it was before. In addition, Eyefinity 2 supports HD3D stereo image output. It supports the combination of three monitors that work in 3D mode.

Improved tessellation

AMD's Radeon HD 7000 family of graphics cards feature a ninth generation tessellator and have seen significant performance gains in geometry processing in modern games. The core GCN still includes two Graphics Engines, but where previously they contained blocks for tessellation and rasterization, now they consist of an arbitrary number of pipelines designed to process geometry and pixels.

AMD Radeon HD 7800 graphics cards support HDMI interface 1.4a, which allows you to display a picture of 120 Hz (60 Hz for each eye), which allows you to display a 3D image. With more early versions HDMI was not possible. Starting in December, AMD included HD3D and Eyefinity interoperability in their drivers.

DirectX 11.1

Video cards of the Radeon 7000 family will support the upcoming DirectX 11.1. It is too early to say what this will give in practice, since DX 11.1 will be released alongside Windows 8. The main advantages of the new API are indicated as follows:

  • Independent rasterization;
  • Flexible combination of graphic computing and video processing;
  • Native Stereo 3D support.

AMD Unified Video Decoder

Represents the hardware part of the graphics AMD processors responsible for decoding the video stream. The Radeon 7000 UVF series has received some enhancements. In general, UVD has retained all the functions of its predecessors, namely support for H.264 / AVCHD, MPEG-2, MPEG-4 / DivX, VC-1 / WMV profile D, Multi-View Codec (MVC), Video Codec Engine ( VCE), AMD Steady Video 2.0. Added support for Dual Stream HD + HD format.

Review of the AMD Radeon HD 7870 video card.Inexpensive alternative to flagships

Quite recently, we told you about the top-end video cards of the new seven-thousandth line of video cards from AMD - the Radeon HD 7970 and the Radeon HD 7950. But, as you know, you cannot succeed with the tops alone. So it's time to talk about the AMD Radeon 7800 Series - a less expensive but still powerful line.

Introduction. Estimated cost

The AMD Radeon HD 7870 video card should be sold in stores at a price starting from 350 US dollars (in our case, it must be converted into rubles at the Central Bank rate). The recommended price for the "little brother", AMD Radeon HD 7850, is $ 250. It is necessary to understand that in Russia the price will always be slightly higher (according to price.ru, about Quote: AMD Radeon HD 7870 0903 3 for 7870 and about Quote: AMD Radeon HD 7850 0903 3 for 7850). Therefore, if I intend to buy one of these graphics cards, I would expect to spend about $ 50-80 more in each case. But even if you do not take into account the margins Russian market, the cost of each of the video cards is very high and for that kind of money, buyers will count on very high performance. Let's find out what we get by buying one of these cards.

7800 Series Architecture

The 7800 sub-line is built on a new GPU, codenamed Pitcairn.

This GPU is very attractive with its price / performance ratio. For most buyers of the 7900-series graphics card, its performance will be overkill, and not everyone wants to overpay. more money if they don't see the difference. In turn, HD 7700 video cards may turn out to be rather weak for comfortable gaming on maximum settings in the popular resolution 1920x1080.

This is a bit like the history of the AMD Radeon HD 5850 graphics card.

Remember this one? While it could not be turned into a HD 5870 by simply flashing the BIOS, it won the love of customers thanks to optimal parameters, which allowed running modern games at maximum settings, while maintaining an adequate price. The current generation of HD 7800 video cards may well fill this niche.

The new GPU carries 20 GCN (Graphic Core Next) Compute Units. Recall that in the GPU Tahiti, which is equipped with the top-end video card Radeon HD 7970, there were 32 of them. Each computational unit contains four vector blocks, and each vector block, in turn, contains 16 computational modules (stream processors) and one scalar.

Thus, the total number of computational modules in the new GPU is 1280 pcs. The number of rasterization units (ROPs) has not changed and remained at 32. The GPU clock speed is 1000 MHz. The amount of video memory is 2048 MB GDDR5. The clock frequency is 1200 (4800 effective) MHz. Memory bus 256 bit. All these characteristics are true for the senior video card of the sub-series - HD 7870.

The younger brother of the Radeon HD 7850 is equipped with the same GPU, only slightly stripped down. Computing units were cut, their number was reduced to 16. Thus, the junior video card carries only 1024 computational modules on board, i.e. exactly half of them in the Tahiti GPU. Accordingly, there are also fewer texture processing units, there are 64 of them left. The GPU clock speed is 860 MHz. The rest of the characteristics remained unchanged (relative to the Radeon HD 7870).

So, as stated above, the Pitcairn GPU is based on the Graphics Core Next (GCN) architecture. This means that he inherited all the solutions from Tahiti (7900 Series). The new GPU is built on 28nm technological process... The video card is equipped with PCI-E 3.0 (Gen3). AMD PowerTune and AMD ZeroCore Power energy saving technologies have not gone anywhere either. AMD Eyefinity 2.0 technology will allow us to connect multiple displays with a maximum total resolution of 16384x16384. 3D support is present and implemented by AMD technology HD3D Technology. AMD also continues to develop technologies to increase system performance using GPUs. In this case, we are offered for use the Video Codec Engine (VCE) technology, which accelerates video encoding by the hardware of the video card, thereby greatly helping central processing unit and reducing the amount of time required for data processing.

The slide above confirms that GPU Pitcairn has completely inherited all the "goodies" from its older brothers. Moreover, the 7700 line is also not deprived of functions, but more on that in the next article.

Judging by the slides from AMD, the new video cards have modest appetites. The older HD 7870 in the load consumes no more than 175 watts. The thermal package of the junior HD 7850 card is 130 watts. When the display is turned off in idle mode, video cards consume less than three watts.

The graphs on the slide look compelling. AMD promises almost double the performance. However, this is not very surprising: the CrossFireX mode has always scaled well. Drivers play a huge role here. I am glad that at least everything is in order here. This is where we move on to studying the structure of video cards.

AMD Radeon HD 7870

As usual, let's start by examining the exterior, then move on to dismantling the cooling system and examining the printed circuit board and elements on it.

The appearance of the video card is absolutely traditional and recognizable. As you may have guessed, a reference engineering sample came to our laboratory. The board length is 245 mm. So far, only one thing can be said about the cooling system: hot air is blown out of the case by means of a turbine. You can also see that the switch between the BIOS chips has disappeared. In fact, looking ahead, I will say that the second BIOS chip also disappeared. From now on, when flashing a video card, there will be a certain risk not to start it anymore. Most will think that this is a minus. However, how often do you flash video cards? Especially if the cores are not unlocked? So I think not very often. And for most users this is a plus, since the lack of such a function leads to a decrease in the cost of the product.

Also, only one CrossFireX connector is visible. This means that we can only combine two video cards in tandem. The situation is similar to the one we discussed above with the microcircuit and the BIOS switch. How many users combine three or more video cards into a bundle? I think that such people are an absolute minority, especially among those who use less-than-top video adapters. Moreover, its absence again reduces the final cost of the product.

On back side there is nothing remarkable, and we move on.

Under the grill for blowing hot air out of the case, there are four video outputs in the usual place - one DVI, one HDMI and two miniDP.

The video card is equipped with two additional power connectors. This can help when overclocking with increasing voltage applied to the GPU. At such times, energy consumption increases dramatically.

For better heat transfer, the place of contact between the heatsink and the GPU and the adjacent area are made of copper. Three copper heat pipes help dissipate heat.

If someone remembers what the board of the reference HD 6870 looks like, then they will understand me in the feeling that I have already seen it somewhere. Indeed, a board with a very similar arrangement of elements was used in the reference HD 6970.

In the center of the PCB is the Pitcairn XT GPU itself, rotated 45 degrees relative to the substrate.


Around the GPU are eight Hynix video memory chips labeled T2C, which means that these chips can operate at up to 5000 MHz.


The heart of the power subsystem is the CHIL CHL 8225G chip. The GPU power subsystem is five-phase. Pay attention to the power phase arrangement; there is one phase to the video memory power supply. The printed circuit board looks thoughtful and neat, there is no feeling that they did it at the last moment "on the knee".

That is where we bring our acquaintance with the Radeon HD 7870 to a close and pass on to examining the Radeon HD 7850.

Radeon HD 7850

Let me remind you that this is the younger brother Radeon graphics HD 7850.

Externally, the video card is no different from its older brother.

And here there are no differences, except for the only connector for additional power supply. Since the HD 7850 consumes only 130 watts, versus 175 watts for the HD 7870, one six-pin connector will be sufficient. The main thing is that it does not leave an imprint on the card's overclocking potential.

There is no difference from the HD 7850 either. We have one DVI, one HDMI and two miniDPs at our disposal.

The cooling system does not differ from that of the Radeon HD 7870. We are offered a copper base at the point of contact between the GPU and the cooling system, and three copper heat pipes for efficient heat dissipation.

As expected, the printed circuit boards of the two video cards are also completely identical. There are no differences in the soldered elements. The only difference is the "cut" phase from the GPU power subsystem. This is definitely enough for stable operation in nominal value, but how the GPU will show itself in overclocking and how stable it will be is another question.


And here is the very heart of the HD 7850 - GPU AMDPitcairnPRO. It is manufactured in China and contains 1,024 computing modules. Recall: the video card Radeon HD 6850 carried 960 computational modules, i.e. the gap is not so great, if you do not take into account the new architecture and look only at the numbers.


On printed circuit board 8 video memory chips with a total volume of 2 GB are wired for this card. The density of one microcircuit is, respectively, 256 MB. The marking has not changed and reads "T2C", which corresponds to the nominal frequency of 5000 MHz. I would very much like this bar to be overcome in overclocking.

Alternative versions of the Radeon HD 7800 Series

As always, most manufacturers will want to move away from reference cooling systems and offer something of their own. Let's see what exactly.

ASUS HD 7870 and HD 7850

ASUS graphics cards with the well-known DirectCU II cooling system differ insignificantly in appearance, but this is not the main thing. The main thing is that the manufacturer promises up to 20% increased performance relative to the reference version.

Club3D HD 7870 and HD 7850

The Club3D company decided not to go far from the drain. The Radeon HD 7870 looks no different from the reference. The younger brother, apparently, got a heatsink for the GPU personally with one heat pipe and a fan. If the cooling of the rest of the elements did not suffer, then everything is fine.

Gigabyte HD 7870 and HD 7850

Gigabyte decided to equip the 7800 series with its own proprietary cooling systems, as well as increase the clock speeds. The HD 7850 video card is content with a cooling system with two fans, while the Radeon HD 7870 gets a cooling system with three fans. Outwardly, there is nothing to complain about, except for the well-known problem with the removal of hot air outside the case.

HIS HD 7870 and HD 7850

HIS has equipped new products with its proprietary IceQ X cooling systems. These COs have always been famous for their good efficiency. The younger video card got only two heat pipes, while the older video card got all four.

MSI HD 7870 and HD 7850

The TwinFrozr III cooling system is considered highly efficient, but the price tag always goes up noticeably. It often happens that it is easier to take the video card with the next highest performance. But nobody canceled the advantages in the form of high efficiency and low noise level.

PowerColor HD 7870 and HD 7850

PowerColor introduced two versions of the Radeon HD 7870 and one Radeon HD 7850. The younger HD 7850 will be content with standard system cooling, as far as can be judged by outward appearance... This is not a big deal, since the HD 7850 has very low power consumption and, consequently, heat dissipation. There are two options for the HD 7870: one reference and one with a PCS + cooling system.

Sapphire HD 7870 and HD 7850

Sapphire's video cards will be equipped with cooling systems very similar to those of the FleX brand. There is no reason to doubt the effectiveness of these COs, since we have already tested similar video cards, and, even with much hotter manners, the temperatures remained within reasonable limits.

XFXHD 7870

XFX has presented at the moment only the older video card Radeon HD 7870. It will be equipped with two fans. We have already seen a similar design in the 7900 series video cards from this manufacturer.

Overclocking and temperatures

Let's start with the younger video card, Radeon HD 7850


The nominal clock speeds are 860 MHz for the GPU and 1200 (4800 effective) MHz for the video memory. Cooling systems in the references inspire confidence, so you can safely count on a successful overclocking.


Without raising the voltage, the video card was overclocked to 1025 MHz for the GPU and 1375 (5500) MHz for the video memory. These are good results. The fan speed was 40%. Higher values ​​made work near the booth impossible. Still, a series of 7000 video cards cannot be compared even with vacuum cleaners, they are quieter. Of course, everything is fine in nominal value, video cards cannot be heard in idle. But if you accelerate it and crank it up manually, then that's it, turn off the light.


The nominal frequencies for the older HD 7870 video card are 1000 MHz for the video processor and 1200 (4800) MHz for the video memory.


As in the case with the lower-end video card, we turned the fan speed up to 40%, which helped to lower the temperature. The video processor was able to operate stably at a frequency of 1120 MHz. But the video memory was very upsetting. Unfortunately, it was not able to work stably at higher frequencies at all. Most likely, this is a special case and we were just out of luck. Probably one of the video memory chips was not in the best shape.


The operating temperatures of the two new products practically do not differ from each other in nominal terms. The older video card HD 7870, as expected, loses several degrees under load, this is normal. In overclocking, the temperatures are lower due to the increased speed of the cooler up to 40%. At the same time, the HD 7950 turns out to be much more hot video card... But no one can compete with the HD 6970 in terms of heat dissipation. As befits the previous generation of video cards, it is the hottest video adapter among all the test participants.

Competitors

To compare performance, we took two video cards: AMD Radeon HD 7950 and AMD Radeon HD 6970.

AMD Radeon HD 7950

The second most powerful video card from AMD today is harmful to single chips. We have already told you about this video card. I wonder how the novelties will behave against its background. On the side of the HD 7950 video card, the amount of memory is three gigabytes and the number of stream processors is equal to 1792 pieces.

AMD Radeon HD 6970

This video card is the TOP of the previous generation. It has high performance sufficient for modern games. Of course, at 2560 x 1600 it has nothing to catch, but more powerful video cards are bent in such modes. The amount of video memory is 2048 MB. The number of stream processors is 1536 pieces, they operate at a frequency of 880 MHz.

  • Power supply unit - Corsair HX850W

Test results results AMD testing Radeon HD 78xx in Dirt 3





The new line shows good performance. In most cases, the overclocked Radeon HD 7850 is very close to the stock Radeon HD 7870. The latter in overclocking in most cases successfully competes with the Radeon HD 7950 in the nominal value. Everything is natural. The performance of the HD 6970 graphics card jumps a lot from application to application. In some places it outperforms the HD 7870, and in some places it loses to the HD 7850. On the whole, the performance of the new line is very pleasing.

Conclusion

The AMD Radeon HD 7800 series is very successful. At a lower cost, the Radeon HD 7870 in overclocking often catches up with a video card from the older top line - HD 7950. This will save those who want more performance for less money.

I liked it very much temperature conditions new video cards. They are really cold. Under load at runoff frequencies, the HD 7870 warmed up to 68 degrees, and the HD 7850 to 66 degrees. This is a very good result with such performance. This becomes very noticeable if you start comparing all the results with the HD 6970 video card.

I really didn't like the noise of the video cards, if you set at least 50% of the cooler's speed. I can't even imagine who can work near a computer if the rotation speed is set to more than 50%.

Once prices are settled, new items are a great investment. This process usually takes a month or two. Most importantly, the price / performance parameter has not shifted towards higher prices.
