AMD Radeon HD 7870 video card review. Inexpensive alternative to flagships
More recently, we told you about the top video cards of the new seven-thousandth line of video cards from AMD - Radeon HD 7970 and Radeon HD 7950. But, as you know, you will not exceed one thores. Therefore, it's time to talk about AMD Radeon 7800 Series - less expensive, but still a productive line.
Introduction. Approximate value
The AMD Radeon HD 7870 video card should be sold in stores at a price starting from 350 US dollars (in our case, you need to recalculate on rubles at the rate of the Central Bank). The recommended price for the "younger brother", AMD Radeon HD 7850 is $ 250. It should be understood that in Russia the price will always be somewhat higher (according to the price.ru, about Request Price: AMD Radeon HD 7870 0903 3 for 7870 and about Request Price: AMD Radeon HD 7850 0903 3 for 7850). Therefore, assuming to buy one of these video cards, I would calculate spend about 50-80 dollars more in each case. But even if not to take into account the markups russian marketThe cost of each of the video cards is very high and for such money buyers will count on very high performance. Let's find out what we get, bought one of these cards.
Architecture 7800 Series.
Vinema 7800 is built on the new GPU codenamed Pitcairn.
This GPU very attracts the price / performance ratio. For most buyers of the 7900 video card, its performance will be redundant, and not everyone wants to overpay more moneyIf they won't see the difference. In turn, HD 7700 video cards may be weak for a comfortable game on maximum settings In the popular resolution of 1920x1080.
This is a little resembles the history of the AMD Radeon HD 5850 video card.
Remember such? The fact that it could not be turned on a simple flashing BIOS in HD 5870, she won the love of buyers thanks to the optimal parameters that allowed modern games on the maximum settings, while retaining the adequate price. The current generation of HD 7800 video cards may well take this niche.
The new GPU carries 20 GCN blocks (Graphic Core Next) Compute Unit. Recall that in the GPU Tahiti, which is equipped with a top video card RADEON HD 7970, they were numbered 32. Each computing unit carries four vector blocks, and each vector block, in turn, is 16 computing modules (streaming processors) and one scalar.
Thus, the total number of computing modules in the new GPU is 1280 pcs. The number of rasterization blocks (ROPS) has not changed and remained equal to 32. The GPU clock frequency is 1000 MHz. The volume of video memory - 2048 MB GDDR5. The clock frequency 1200 (4800 effective) MHz. 256 bits memory bus. All of these characteristics are valid for senior seminacy video card - HD 7870.
The younger brother Radeon HD 7850 is equipped with the same GPU, only slightly trimmed. Computing blocks were cut, their number was reduced to 16. Thus, the youngest video card carries on board only 1024 computing modules, i.e. Exactly half of their number in GPU Tahiti. Accordingly, texture processing blocks have also become less, there are 64 pieces left. GPU clock frequency is 860 MHz. The remaining characteristics remained unchanged (relative to the Radeon HD 7870).
So, as mentioned above, GPU Pitcairn is based on the Graphics Core Next architecture (GCN). This means that by inheritance he got all the solutions from Tahiti (7900 Series). The new GPU is built on 28-nm technological process. The video card is equipped with PCI-E 3.0 (Gen3). Nothing and Energy Saving Technologies AMD PowerTune and AMD ZEROCORE POWER. AMD Eyefinity 2.0 technology will allow us to connect many displays with a maximum total resolution of 16384x16384. 3D support is present and implemented by forces aMD technology HD3D TECHNOLOGY. AMD also continues to develop technologies for increasing the performance of the entire system by GPU. In this case, we offer the use of Video Codec Engine (VCE) that accelerates video card coding by hardware cards, thereby helping very much central processor and reducing the required amount of data on data processing.
The slide above confirms that GPU Pitcairn completely inherited all the "buns" from the older brothers. Moreover, the line 7700 is also not deprived of functions, but about it in the following material.
If you judge the slides of AMD, then new video cards have modest appetites. The eldest HD 7870 in the load consumes no more than 175 W. The heat pump of the younger card HD 7850 is 130 watts. When the display is disconnected in the idle mode, the video card consumes less than three watts.
Graphs on the slide look convincing. AMD promises almost two performance gains. However, it is not much surprised: the CrossFirex mode is always finely scaled. Drivers play great importance. I am glad that at least here everything is in order. This goes to the study of the structure of video cards.
AMD Radeon HD 7870
As usual, let's start with the study of appearance, then we turn to the dismantling of the cooling system and the study of the printed circuit board and items on it.
The appearance in the video card is absolutely traditional and recognizable. As you already guessed, a reference engineering sample fell into the laboratory. The length of the board is 245 mm. About the cooling system can be said so far only one thing: hot air is blown out of the housing using a turbine. It is also seen that the switch between BIOS chips disappeared. In fact, running forward, I will say that the second BIOS chip also disappeared. From now on, when flashing a video card will be a certain risk. Most will think that it is minus. However, how often do you flash the video cards? Especially if the kernels are not unlocked? So I think that is not particularly often. And for most users it is a plus, since the lack of such a function leads to a decrease in product value.
Also seen only one CrossFirex connector. This means that we can combine only two video cards in tandem. The situation is similar to the one that we looked at the above with the microcircuit and the BIOS switch. How many users are combined in a bunch of three and more video cards? I think that people are an absolute minority, especially among those who use not the top video adapters. In this case, its absence again reduces the final cost of the product.
On the back side There is nothing remarkable, and we go further.
Under the grill for blowing hot air outside the body in the usual location, four video outputs are located - one DVI, one HDMI and two miniDP.
The video card is equipped with two additional power connectors. It can help with overclocking with an increase in voltage supplied on the GPU. At such moments, power consumption is growing greatly.
For better heat transfer, the contact location of the radiator with GPU and the adjacent area are made of copper. Help in heat dissipation three copper heat pipes.
If someone remembers the reference HD 6870 card looks like, it will understand me feeling that I have already seen it somewhere. Indeed, the board with a very similar arrangement of the elements was used in the reference HD 6970.
The center of the printed circuit board is located the GPU Pitcairn XT itself, rotated at 45 degrees relative to the substrate.
Around the GPU is located eight chips of the HYNIX video memory with T2C marking, which indicates that chip data can operate with a frequency of up to 5000 MHz.
The heart of the power subsystem is chil chl 8225g microcircuit. Pyal phase GPU nutrition subsystem. Pay attention to the location of the phase of the power supply. There are one phase one phase of nutrition. The printed fee looks thoughtfully and gently, there is no feeling that they did at the last moment "on the knee."
On this we finish acquaintance with the Radeon HD 7870 board and proceed to the study of the Radeon HD 7850.
Radeon HD 7850.
Let me remind you that this is the younger fellow video card Radeon. HD 7850.
Externally, the video card is no different from his older fellow.
And there are no differences, except for the only additional power connector. Since the HD 7850 consumes only 130 watts, against 175 watts in HD 7870, then one six-sighted connector will be enough. The main thing is that this does not impose a fingerprint on the acceleration potential of the card.
There are also no differences from HD 7850. At our disposal there is one DVI, one HDMI and two miniDP.
The cooling system is not different from that of the Radeon HD 7870. We are offered a copper base at the GPU contact site and the cooling system, and three copper heat pipes for efficient heat removal.
As expected, the printed circuit boards in two video cards are also completely identical. No differences in the disintegration elements are observed. The only difference is the "drank" phase with the GPU power subsystem. For stable work in the denomination of this, it is for sure, but how the GPU will show itself in acceleration and how stable is another question.
And here is the Heart HD 7850 - GPU AMDPITCAIRNPRO. It is produced in China and carries the 1024 computing modules. Recall: the Radeon HD 6850 video card carried 960 computing modules, i.e. The separation is not so great if you do not take into account the new architecture and watch only on the numbers.
On the pCB This card is smoked 8 microcircums of video memory with a total volume of 2 GB. The density of the same chip, respectively, 256 MB. The marking has not changed and says "T2C", which corresponds to the nominal frequency of 5000 MHz. I would love to be overcome in acceleration in acceleration.
Alternative Versions Radeon HD 7800 Series
As always, most manufacturers want to move away from reference cooling systems and suggest something from their own. Let's see what it is.
ASUS HD 7870 and HD 7850
ASUS's video card with a well-known all-known Cooling system DirectCu II externally differs very slightly, but it is not the main thing. The main thing is that the manufacturer promises up to 20% increased productivity relative to the reference option.
Club3D HD 7870 IHD 7850
Club3D decided not to leave far from the drain. The Radeon HD 7870 does not differ from the reference. The younger fellow, apparently, got a radiator personally for GPU with one heating tube and a fan. If the rest of the elements did not suffer, then everything is fine.
Gigabyte HD 7870 IHD 7850
Gigabyte decided to equip the 7800 series with its corporate cooling systems, as well as increase clock frequencies. The HD 7850 video card is content with two fans cooling system, and the Radeon HD 7870 has gained the cooling system with three fans. Outwardly, it is not for anything other than a well-known problem with the conclusion of hot air outside the hull.
HIS HD 7870 IHD 7850
HIS has equipped the novelties with its branded ICEQ X cooling systems. These with always famous for good efficiency. The younger video card got only two heat tubes, while the older video card received all four.
MSI HD 7870 IHD 7850
The cooling system TWINFROZR III is considered highly efficient, but the price tag is always noticeably rising. It often happens so that it is easier to take a video card following performance. But nobody canceled advantages in the form of high efficiency and low noise.
PowerColor HD 7870 and HD 7850
PowerColor introduced two versions of the Radeon HD 7870 video card and one Radeon HD 7850. The youngest HD 7850 will be content with standard system cooling how much can be judged by appearance. It is not scary, since the HD 7850 has very low power consumption, and, accordingly, heat release. For HD 7870, two options are harvested: one reference, and one - with the Cooling system PCS +.
Sapphire HD 7870 IHD 7850
Sapphire production video cards will be equipped with cooling systems, very similar to Flex. To question the effectiveness of these CO has no reason, since we have already tested similar video cards, and, even with much more hot nuts, the temperatures remained within reasonable limits.
XFXHD 7870.
XFX has introduced this moment Only the older video card RADEON HD 7870. It will be equipped with two fans. We have already seen such a design of the 7900 series of this manufacturer in the video cards.

Overclocking and temperature
Let's start with the younger video card, Radeon HD 7850
Nominal clock frequencies are 860 MHz for the graphics processor and 1200 (4800 efficient) MHz for video memory. Cooling systems in references inspire confidence, so you can safely count on successful acceleration.
Without an increase in voltage, the video card managed to dispersed to 1025 MHz on GPU and 1375 (5500) MHz on video memory. These are good results. The speed of rotation of the fans was 40%. Higher values \u200b\u200bdid work near the stand impossible. Still, a series of seven thousandcrackers cannot be compared even with vacuum cleaners, they are quieter. Of course, in the par, everything is fine, video cards are not heard in simple. But if you dispel it and unscrew the speed manually, then all the carcasses light.
The nominal frequencies for the older video card HD 7870 are 1000 MHz for the video processor and 1200 (4800) MHz for video memory.
As in the case of the younger video card, we twisted the cooler speed to 40%, which helped lower the temperature. The video processor was able to function steadily at a frequency of 1120 MHz. But the video memory strongly grieved. Unfortunately, she could not work consistently at elevated frequencies. Most likely, this is a special case and we are simply not lucky. Probably one of the video memory chips was not in the best form.
The working temperatures of two new products are practically no different from each other in the par. The older video card HD 7870, as it should be relying, loses several degrees in the load, this is normal. In the acceleration of temperature below due to increased cooler speed to 40%. At the same time, the HD 7950 turns out to be much more hotcard. But no one can compete on heat dissipation with HD 6970. As is relying the previous generation of video cards, it is the hottest video adapter among all testing participants.
Competitors
For performance comparison, we took two video cards: AMD Radeon HD 7950 and AMD Radeon HD 6970.
AMD Radeon HD 7950
The second in the power of the video card has AMD to date in the country. We have already told you about this video card. I wonder how new items will behave on her background. On the side of the video card HD 7950, the amount of memory in three gigabytes and the number of streaming processors, equal to 1792 pcs.
AMD Radeon HD 6970
This video card is the top of the previous generation. It has high performance sufficient for modern games. Of course, in the resolution of 2560 x 1600, it has nothing to catch, but more powerful video cards are bent in such modes. The volume of video memory is 2048 MB. The number of streaming processors is 1536 pcs, they function at a frequency of 880 MHz.

Test results results aMD testing Radeon HD 78xx in Dirt 3
New ruler shows good performance. In most cases, the overclocked Radeon HD 7850 is strongly approaching stock Radeon HD 7870. The latter in acceleration in most cases successfully competes with the Radeon HD 7950 in the par. Everything is natural. The HD 6970 video card performance is very much jumping from the application to the application. In some places it wins HD 7870, and in some places HD 7850. In general, the performance of the new line is very pleased.
Conclusion
AMD Radeon HD 7800 series turned out to be very successful. At a lower cost of Radeon HD 7870 in acceleration, the video card is often caught up with a video card from the older top line - HD 7950. This will save those who want to get more performance for smaller money.
Really liked temperature modes New video cards. They are really cold. In the load under the stock frequencies HD 7870 heated to 68 degrees, and HD 7850 is up to 66 degrees. This is a very good result with such performance. It becomes very noticeable if you start comparing all the results with the HD 6970 video card.
I really didn't like the noise of video cards, if you set at least 50% of the coolers. I can not even imagine who can work near the computer if you set the speed of rotation more than 50%.
As soon as prices are defined, the novelties will become an excellent investment of money. Usually this process takes a month or two. The most important thing is that the "price / performance" parameter did not shift towards the price increase.
AMD officially introduced a new series of video cards created on the basis of 28-nm microarchitecture GCN - AMD Radeon HD 7800. At the moment, it includes two models: and. Novelties are based on graphic aMD processors "Pitcairn Pro" and AMD "Pitcairn XT", which operate on the clock frequency of 860 MHz and 1000 MHz, respectively. Thus, the video card will be the second in model row Companies (after AMD Radeon HD 7770) with the title "GHz Edition".
The solution is equipped with 16 computing blocks, 1024 streaming processors, 64-text tubes and 32 rop blocks. The video specifier of the novelty is 256-bit GDDR5 standard chips with a total capacity of 2 GB. Their nominal clock frequency is at the level of 1200 MHz, and an effective - 4800 MHz.
The external interfaces of the model includes four ports: DVI, HDMI and two minidisplayport.
The graphic adapter owns a better structure that includes: 20 computing blocks, 1280 streaming processors, 80 textural and 32 ROP blocks. The video subsystem of this novelty, like a set of its external interfaces, is identical to the model.
Mass selling solutions and starts from March 19. The recommended retail price of the novelty data will be $ 249 and $ 349, respectively. Comparative table of technical specification of new video cards series AMD Radeon HD 7800 It has the following form:

Review Radeon R9 270 | New or updated?
"GPU PITCAIRN has 20 compute blocks (Compute Units - Cu), each of which consists of four vector blocks (vector units - VU). Each vector block, in turn, includes 16 streaming processors and one texture processing unit. In sum we get 1280 streaming processors and 80 textural blocks for senior representative of the 7800th line. In Radeon HD 7850. The trimmed version of the GPU Pitcairn is used: four computing blocks are removed, which gives in the amount of 1024 streaming processors and 64 texture processing units.
AMD has kept all eight rasterization blocks, each of which consists of four COLOR ROP blocks, which gives up to 32 raster operations per cycle. Four 64-bit memory controllers are connected to rasterization blocks through a common interface. Thus, we get a 256-bit memory bus. "
So, if RADEON R9 270X. Replace Radeon HD 7870. , then RADEON R9 270. Must be replaced Radeon HD 7850. With a trimmed version of GPU, right? However, if you look at the characteristics, frequencies and prices of the current AMD rule, it turns out an interesting thing.

We were surprised, finding that RADEON R9 270. is not overclocked Radeon HD 7850. , as was expected. It is essentially Radeon HD 7870. With lowered 75 MHz, the core frequency, an increased 200 MHz frequency of video memory GDDR5 and lowered by a 25 W thermal package at a price of $ 180.
First, let's consider frequencies. It seems that the reduced core frequency and the faster RAM memory are needed in order to ensure the performance of the old level Radeon HD 7870. . However, this makes no sense. Why underestimate the frequency of Pitcairn and spend more money for more expensive GDDR5 memory? We have only one guess: AMD wants to get performance Radeon HD 7870. And at the same time fit into the limit characteristic of one six-contact auxiliary power connector. As you can see, the thermal package RADEON R9 270. is 150 W against 175 watts Radeon HD 7870. . AND RADEON R9 270X. , I. Radeon HD 7870. Two auxiliary connector require.
As for the price of $ 180, it turns out that RADEON R9 270. $ 20 cheaper recently represented RADEON R9 270X. which has the same memory frequency (1400 MHz), but with an increased 125 MHz core frequency (1050 MHz). Suppose cards at the time of exit will really cost $ 180. In this case, RADEON R9 270. will be $ 10 cheaper GeForce GTX 660. - its main competitor from NVIDIA. In addition, with such a price RADEON R9 270. on average will be cheaper Radeon HD 7870. which over the past few months has become noticeably more accessible. But it was a temporary phenomenon, since retailers wanted to unload warehouses. From AMD we have already learned that Radeon HD 7870. and Radeon HD 7850. Soon they will disappear from the sale.
It is also worth noting that using the Pitcairn / Curacao processor, RADEON R9 270. and RADEON R9 270X. Do not support new feature AMD Trueaudio. To do this, you will need Radeon R7 260 or RADEON R9 290. . As in other chips on the GCN architecture, the MANTLE AMD API support is introduced in it, although the success of this technology is still very early.
Keep in mind that new series RADEON R9 (270, 270x, 280x, 290 and 290x) does not include AMD Never Settlers. For example, buying Radeon R7 260x. In the American online store, you can choose two games from the silver level of AMD NEVER Settle. In addition, AMD provides customers Battlefield 4. . In this, it relies on retailers and partners of the company, independently choosing models with a game coupon, and such coupons are only 1000.
So, the main question: how RADEON R9 270. looks in comparison with Radeon HD 7870. ? As far as the novelty is good next to GeForce GTX 660. ? Test results will be helped with these questions. But first let's consider our test sample.
SAPPHIRE DUAL-X R9 270
SAPPHIRE DUAL-X R9 270 is a moderate "factory" acceleration. The processor processes the commands at a frequency of 945 MHz (from the initial 925 MHz), and the GDDR5 memory has a frequency of 1400 MHz. However, ours RADEON R9 270. Works at frequencies similar to the reference AMD card.
The Dual-X card uses its own Sapphire cooler with two axial fans.
Sapphire. RADEON R9 270. Equipped with two DVI, HDMI and DISPLAYPORT outputs. Since the thermal card package is 150 W, it has only one six-contact auxiliary power connector. AMD requires that RADEON R9 270. Restricted only with one CrossFire connector, that is, you can only combine in the bundle of two cards.
Review Radeon R9 270 | Test booth and benchmark
In our laboratory, we almost completely got rid of mechanical hard disksand instead we use solid-state drivesfor which uncharacteristic delays associated with the introduction / output. Samsung sent drives to our offices Samsung 840 pro. By 256 GB, so they are used as standard.
Naturally, the discrete schedule requires a stable power supply, for this XFX sent us the PRO850W power supply with 80 Plus Bronze certificate. Modular BP has one +12 V bus, calculated on 70. According to XFX, this model Provides continuous (non-peak) power up to 850 W at a temperature of 50 degrees Celsius (noticeably more than in most buildings).
We tested RADEON R9 270. Along with three other cards based on Pitcairn / Curacao: Radeon HD 7850. , Radeon HD 7870. and RADEON R9 270X. . Also to measure the difference between RADEON R9 270. and the younger model we included in testing Radeon R7 260x. With Bonaire chip (it replaces Radeon HD 7850.). NVIDIA competitors represent GeForce GTX 650 Ti Boost and GeForce GTX 660. .

Review Radeon R9 270 | Test results
Call of Duty: Ghosts
Let's start S. new game Call of Duty: Ghosts. We will soon publish a full-fledged performance analysis in this game, and today you will see what is capable of in this long-awaited game of the video card at a price of $ 200 at a resolution of 1920x1080 pixels with high quality Details.
RADEON R9 270. In terms of performance is not inferior Radeon HD 7870. That we expected. The novelty is a bit faster GeForce GTX 660. And significantly overtakes Radeon HD 7850. and GeForce GTX 650 Ti Boost showing almost the same results.
GPU Curacao / Pitcairn demonstrate the lowest fluctuation of frame time, although the game generates much more bursts than I would like. But let's not forget that the game is still quite new, and quite possible, future patches will add stability.
Battlefield 4.
Battlefield 4. Just a few weeks older than the new Call of Duty, however, its Frostbite 3 engine, no doubt, is more modern. How to show yourself RADEON R9 270. in a new generation blockbuster?

IN Battlefield 4. frame time fluctuations lower than in Call of Duty: Ghosts, while on the chart radeon cards There is a little more jumps.
Metro: Last Light
Metro Series is known for high loads on graphic system For the highest detail settings. To obtain an acceptable frame rate with our cards, we had to reduce the quality of graphics.
It was possible to be reinforced and lower a few more parameters, because in the most "hard" for the graphics subsystem of places the frame rate goes under the mark of 30 FPS. Whatever it was, the finish order does not differ from the test results in Call of Duty and Battlefield 4. .
In general, Metro: Last Light shows low frame time fluctuations, but, at the same time, there are several noticeable jumps. Moreover, this effect is noticeable in all tested cards.

Bioshock Infinite works on the new Epic Unreal engine. As is known, it is less demanding of the graphics subsystem.
We first see how RADEON R9 270. overtakes old Radeon HD 7870. . Here seems to play a key role bandwidth Memory, not the speed of the graphics processor.
GeForce GTX 660. in this game showed itself just wonderful, overtaking RADEON R9 270X. .
It seems that the engine is well optimized as we observe very low delays between the frames. Worry about nothing.
Tomb Raider.

As always, Radeon HD 7870. And the new one in the sample of 300 frames.
COMPANY OF HEROES 2
Company of Heroes 2 is a sequel to the popular RTS World War II from the Relic Studio. We saw how it provides high load on CPU and GPU, so let's take a look at the results.
Radeon cards give quite expected indicators, while NVIDIA GeForce accelerators stayed behind. It seems that the developers of the drivers still have to work over the game.
On the schedule chart of frame time, all cards demonstrate a strange behavior. With regular intervals, bursts are observed for up to 5-10 seconds. We were not sure how these indicators would affect the calculations of average performance, therefore, the results of the Company of Heroes from the general diagram on the last page were excluded.
Review Radeon R9 270 | Power consumption tests and temperature
Our German colleagues received a video card from ASUS with factory overclocking, so our results with low-frequency card may differ from the results of editors from Germany.
We see good energy efficiency indicators in a simple when working with one monitor. However, AMD cards are noticeably losing NVIDIA when connecting multiple displays.
GEFORCE graphic adapters win when playing Blu-ray, but AMD cards return their positions in gaming and computing tasks.
Especially impressive New RADEON R9 270. Since it has a factory overclocking.
This schedule does not talk about a reference cooler RADEON R9 270. However, ASUS Direct CU II copes well with the heat generation of the chip, and provides a low temperature in long gaming tasks. Under the load, the temperature of the graphics processor does not exceed 70 degrees Celsius.
