Device description amd radeon hd 7800 series. Video cards
AMD Radeon HD 7850M- video card supporting DirectX 11, based on GCN architecture. The card is designed for medium and large laptops. It is one of the most productive video cards of 2012. It is manufactured using a 28 nm process technology.
Radeon 7800M series adapters are built on the Cape Verde chip, as well as Radeon HD 7770 for desktop computers, with 640 1D shader cores and 40 texture units. But in terms of clock frequency, the HD 7850M is inferior to the HD 7870M card (675 MHz to 800 MHz, respectively). Overall, the 7850M is about on par in terms of performance with HD 7750 for desktops.
As expected, the Radeon HD 7850M has become a competitor to the GeForce GTX 560M from NVIDIA, since, in addition to higher performance, it also shows a lower level of power consumption (same as the GeForce GTX 660M). Thus, modern demanding games run smoothly at medium and high settings.
A special feature of the 7850M is the presence of a new UVD3 video decoder for decoding MPEG-4 AVC/H.264, VC-1, MPEG-2, Flash, Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD video formats .
The 7800M series cards also support automatic switching technology between integrated and discrete graphics. This feature is called Enduro, it is similar to NVIDIA's Optimus technology. Additionally, the HD 7850M can support up to 6 monitors simultaneously using Eyefinity technology when Enduro is disabled.
Next feature HD 7850M is the ZeroCore function, which automatically reduces power consumption in sleep mode with the display turned off. PowerTune technology allows the video card to overclock as long as power consumption is within acceptable limits. For example, the frequency may decrease when running FurMark and OCCT, and increase in some games (Planet, Crysis or Resident Evil 5).
Built-in HD audio processor capable of transmitting sound High Quality(TrueHD or DTS Master Audio formats) using HDMI and DisplayPort (for example, Blu-ray video). In addition, using DDMA technology, it is possible to output sound from several devices simultaneously.
Power consumption level 7850M much lower than the 7870M due to the lower core clock.

The line was produced in March 2012. Based on it, the following models were released:
- HD7850;
- HD7870;
- HD7890.
At this moment the lineup no longer available. At the start of sales, the average price in stores was $249 and $349.
Review
At AMD, after entering a new technological process, it was decided to divide the overall production series into subgroups. Therefore, a total of 4 lines were formed based on the 28nm process technology, which are presented in the table:
The HD 7800 with the "Pitcairn" GPU uses the Graphic Core Next microarchitecture. The series was launched in March 2012 and is no longer in production today.
At one time, video cards from Pitcairn were quite popular and showed an excellent price/quality ratio. As of 2018, the current series is not popular and it is extremely difficult to find a device in new condition. Despite the fact that the graphics core is already outdated, when combined with a powerful processor, a PC can run various games at medium and high settings.
What games will run on the AMD Radeon HD 7800 Series
Video cards were released back in 2012, but they can still be used on modern toys. Tests in AMD Radeon HD 7800 Series games were carried out with the following hardware:
- Processor: Core I5 6500 3.2 GHz.
- RAM: 16 GB DDR4 2133 Dual.
- HDD: Hitachi 1TB.
- Motherboard: Asus H170M-Plus.
- Resolution: 1920x1080px.
The results are as follows:
| Name of the game | Graphics quality | |
| Assassins Creed Syndicate | Hight | 31 |
| WarThunder | Cinema (Ultra) | 55-65 |
| Quantum Break | Average | 30-42 |
| Assassins Creed Unity | Average | 30 |
| Shadow Warrior 2 | High | 35-45 |
| Dying Light | High | 40-50 |
| Fallout 4 | Ultra | 38-43 |
| GTA 5 | Above average | 45-50 |
| DOOM | High | 40 |
| Rise Of The Tomb Raider | High | 30-40 |
| Warface | High | 90-100 |
| The Witcher 3: Blood and Wine | High | 25-35 |
| World Of Tanks | High | 60-80 |
Overall performance largely depends on the correct combination of processor and video card. If you take a powerful modern generation processor like Ryzen or Core I5, then they will be able to show high FPS in most modern games, even with an old video card.
After analysis technical characteristics and tests in games, we come to the following conclusions: it is not recommended to buy for powerful games in 2018; it is better to choose newer models.
The performance will be sufficient for comfortable homework and for launching multiplayer games like CS:GO, World Of Tanks.
How to overclock a video card
To achieve maximum performance, you can overclock the AMD Radeon HD 7800. To do this, you will need to install the driver and configure it.
The main changes need to be made in the “Games” section. If you use a modern driver, profiles can be configured individually for each video game.
Go to the desired profile and go to the “Frame Rate Control” setting. By default, the video card squeezes out maximum FPS and spends all resources on it.
For a comfortable game of shooters, 60 frames per second is enough. For CS:GO, WarFace, WarThunder, it is enough to set the limit to 70 FPS.
Setting OverDrive allows you to adjust operating parameters: GPU and memory frequencies, fan efficiency and power consumption levels. These parameters must be configured individually for each PC build.

Review of the AMD Radeon HD 7870 video card. Inexpensive alternative to flagships
Just 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 won’t succeed with tops alone. Therefore, it's time to talk about the AMD Radeon 7800 Series - a less expensive, but still productive 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 is necessary to convert it into rubles at the Central Bank exchange 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 Request for price: AMD Radeon HD 7870 0903 3 for 7870 and about Request for price: AMD Radeon HD 7850 0903 3 for 7850). So if I were to buy one of these graphics cards, I would expect to spend about $50-$80 more in each case. But even if you don’t take into account the markups on the Russian market, the cost of each video card is very high and for that kind of money, buyers will expect very high performance. Let's find out what we get when we buy one of these cards.
7800 Series Architecture
The 7800 sub-series is built on a new GPU codenamed Pitcairn.
This GPU is very attractive due to its price/performance ratio. For most buyers of a 7900 line video card, its performance will be excessive, and not everyone wants to pay more money if they don't see a difference. In turn, HD 7700 video cards may be too weak for comfortable gaming at maximum settings in the popular 1920x1080 resolution.
This is a bit like the story of the AMD Radeon HD 5850 video card.
Remember this one? Despite the fact that it could not be converted by simply flashing the BIOS into the HD 5870, it won the love of buyers thanks to its optimal parameters, which made it possible to run modern games at maximum settings while maintaining an adequate price. The current generation of HD 7800 video cards may well occupy this niche.
The new GPU carries 20 GCN (Graphic Core Next) Compute Units. Let us recall that in the Tahiti GPU, which is equipped with the top-end Radeon HD 7970 video card, there were 32 of them. Each computing unit contains four vector blocks, and each vector block, in turn, contains 16 computing modules (stream processors) and one scalar.
Thus, the total number of computing modules in the new GPU is 1280. The number of rasterization units (ROPs) has not changed and remains equal to 32. The GPU clock frequency is 1000 MHz. Video memory capacity is 2048 MB GDDR5. Clock frequency 1200 (4800 effective) MHz. Memory bus 256 bits. All these characteristics are valid for the senior video card of the subseries - HD 7870.
The younger brother Radeon HD 7850 is equipped with the same GPU, only slightly cut down. The computing units were cut down, their number was reduced to 16. Thus, the low-end video card carries only 1024 computing modules on board, i.e. exactly half of their number in GPU Tahiti. Accordingly, there are also fewer texture processing units, there are 64 of them left. The GPU clock frequency is 860 MHz. The remaining characteristics remained unchanged (relative to the Radeon HD 7870).
So, as mentioned 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 using a 28nm process technology. The video card is equipped with PCI-E 3.0 (Gen3). The energy saving technologies AMD PowerTune and AMD ZeroCore Power have not gone away 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 using AMD HD3D Technology. AMD also continues to develop technologies for increasing the performance of the entire system using GPUs. In this case, we are offered the Video Codec Engine (VCE) technology, which accelerates video encoding by video card hardware, thereby greatly helping the central processor and reducing the required amount of time for data processing.
The slide above confirms that the Pitcairn GPU 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 AMD's slides, the new video cards have modest appetites. The older HD 7870 consumes no more than 175 W under load. The thermal package of the younger HD 7850 card is 130 Watts. When the display is turned off in idle mode, the graphics cards consume less than three watts.
The graphs on the slide look convincing. AMD promises an almost twofold increase in performance. However, this is not very surprising: CrossFireX mode has always scaled well. Drivers play a huge role here. I'm glad that at least everything is okay here. With this we move on to studying the structure of video cards.
AMD Radeon HD 7870
As usual, we’ll start by examining the exterior, then move on to dismantling the cooling system and studying the printed circuit board and elements on it.
The appearance of the video card is absolutely traditional and recognizable. As you may have guessed, we received a reference engineering sample in our laboratory. The length of the board is 245 mm. For now, only one thing can be said about the cooling system: hot air is blown outside the body using a turbine. You can also see that the switch between 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 that it will no longer start. Most will think this is a minus. However, how often do you reflash your 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 absence of such a function leads to a reduction in the cost of the product.
Also, only one CrossFireX connector is visible. This means that we will be able to combine only two video cards in tandem. The situation is similar to what we discussed above with the chip and BIOS switch. How many users combine three or more video cards? I think that such people are an absolute minority, especially among those who use not the most top-end 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 grille for blowing hot air outside the case, four video outputs are located in the usual place - one DVI, one HDMI and two miniDP.
The video card is equipped with two additional power connectors. This can help with overclocking by increasing the voltage supplied to the GPU. At such moments, energy consumption increases significantly.
For better heat transfer, the contact point between the radiator and the GPU and the surrounding area are made of copper. Three copper heat pipes help in heat dissipation.
If anyone remembers what the reference HD 6870 board looks like, they will understand my feeling that I have already seen this somewhere. Indeed, a board with a very similar arrangement of elements was used in the reference HD 6970.
In the center of the printed circuit board 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 frequencies 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 location of the power phases. There is one phase per video memory power subsystem. The printed circuit board looks thoughtful and neat, there is no feeling that it was done at the last moment “on the knee”.
This concludes our acquaintance with the Radeon HD 7870 board and moves on to studying the Radeon HD 7850.
Radeon HD 7850
Let me remind you that this is the younger brother of the Radeon HD 7850 video card.
Externally, the video card is no different from its older brother.
And there are no differences here, except for a single additional power connector. Since the HD 7850 consumes only 130 Watts, versus 175 Watts for the HD 7870, one six-pin connector will be enough. The main thing is that this does not leave its mark on the overclocking potential of the card.
There is also no difference here from the HD 7850. We have one DVI, one HDMI and two miniDP at our disposal.
The cooling system is no different 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 effective 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 at nominal value, but how the GPU will perform when overclocked and how stable it will be is another question.
And here is the very heart of the HD 7850 - the AMDPitcairnPRO GPU. It is made in China and carries 1024 computing modules. Let us remind you: the Radeon HD 6850 video card carried 960 computing modules, i.e. the gap is not that big if you don’t take into account the new architecture and look only at the numbers.
On printed circuit board This card contains 8 video memory chips with a total capacity of 2 GB. The density of one chip is, respectively, 256 MB. The marking has not changed and reads “T2C”, which corresponds to a nominal frequency of 5000 MHz. I would really like to see this bar overcome in overclocking.
Alternative versions of 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
Video cards produced by ASUS with the well-known DirectCU II cooling system differ very slightly 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
Club3D decided not to go far from stock. Radeon HD 7870 looks no different from the reference. The younger brother, apparently, has acquired a personal heatsink for the GPU with one heat pipe and a fan. If the cooling of the remaining elements is not affected, then everything is fine.
Gigabyte HD 7870 and HD 7850
Gigabyte decided to equip the 7800 series with its proprietary cooling systems and also increase clock frequencies. The HD 7850 video card is content with a cooling system with two fans, while the Radeon HD 7870 has a cooling system with three fans. Externally, 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 the new products with its proprietary IceQ X cooling systems. These cooling systems have always been famous for their good efficiency. The junior video card received only two heat pipes, while the senior video card received all four.
MSI HD 7870 and HD 7850
The TwinFrozr III cooling system is considered highly efficient, but it always comes with a noticeable price tag. It often happens that it is easier to take the video card that has the next best performance. But the advantages in the form of high efficiency and low noise levels have not been canceled.
PowerColor HD 7870 and HD 7850
The PowerColor company presented two versions of the Radeon HD 7870 video card and one Radeon HD 7850. The younger HD 7850 will be content with a standard cooling system, as far as one can judge appearance. This is not scary, since the HD 7850 has very low power consumption and, accordingly, heat dissipation. For the HD 7870, two options have been prepared: one reference, and one with a PCS+ cooling system.
Sapphire HD 7870 and HD 7850
Video cards produced by Sapphire will be equipped with cooling systems very similar to the branded FleX. There is no reason to doubt the effectiveness of these COs, since we have already tested similar video cards, and, even with much hotter morals, the temperatures remained within reasonable limits.
XFXHD 7870
XFX has currently presented only the older Radeon HD 7870 video card. 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 junior video card, Radeon HD 7850
Nominal clock speeds are 860 MHz for the GPU and 1200 (4800 effective) MHz for the video memory. The cooling systems in the references inspire confidence, so you can safely count on successful overclocking.
Without increasing 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 working near the stand impossible. Still, the seven thousandth series of video cards cannot be compared even with vacuum cleaners; they are quieter. Of course, everything is fine at face value; you can’t hear the video cards when idle. But if you accelerate it and turn up the speed manually, then that’s it, turn off the lights.
The nominal frequencies for the older HD 7870 video card are 1000 MHz for the video processor and 1200 (4800) MHz for video memory.
As in the case of the junior video card, we turned the cooler speed up to 40%, which helped lower the temperature. The video processor was able to operate stably at a frequency of 1120 MHz. But the video memory was very disappointing. Unfortunately, it was not able to operate stably at higher frequencies at all. Most likely, this is a special case and we were just unlucky. 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 HD 7870 video card, as expected, loses a few degrees in load, this is normal. During overclocking, temperatures are lower due to increased cooler speeds of up to 40%. At the same time, the HD 7950 turns out to be a much hotter 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 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 beats single-chips. We have already told you about this video card. I wonder how the new products will behave against its background. On the side of the HD 7950 video card, there is a memory capacity of three gigabytes and the number of stream processors is 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 a resolution of 2560 x 1600 there is nothing special for it to catch, but in such modes more powerful video cards also bend. The video memory capacity is 2048 MB. The number of stream processors is 1536, they operate at a frequency of 880 MHz.

Test results Test results for AMD 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, when overclocked, in most cases successfully competes with the Radeon HD 7950 at nominal value. Everything is natural. The performance of the HD 6970 video card varies greatly from application to application. In some places it outperforms the HD 7870, and in some places it loses to the HD 7850. Overall, the performance of the new line is very pleasing.
Conclusion
The AMD Radeon HD 7800 series turned out to be very successful. At a lower cost, the Radeon HD 7870 often overclocks the video card from the older top line - HD 7950. This will save money for those who want to get more performance for less money.
Liked it very much temperature conditions new video cards. They are really cold. Under load at stock frequencies, the HD 7870 heated up to 68 degrees, and the HD 7850 - up to 66 degrees. This is a very good result for 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 video cards if I set the cooler speed to at least 50%. I can’t even imagine who would be able to work near a computer if the rotation speed was set to more than 50%.
Once prices are finalized, the new items will be an excellent investment. This process usually takes a month or two. The most important thing is that the price/performance parameter has not shifted towards higher prices.
