Those who for the first time decided to build their own PC or to understand its insides begin to come across a huge number of incomprehensible terms. When we open the housing cover, we see a lot of wires, plates, fans, radiators, etc. To avoid calling the wizard once again and not contacting friends, it's easier to figure out yourself.
Therefore, there is no longer full memory. As a rule, embedded graphics chips are behind their video cards. Editing images and video also does not affect the graphics performance. Here is a fast main processor and lots of memory. The internal graphic block is suitable for speeding up the composition of the image. However, this does not require an especially fast graphics unit. There are differences in quality and efficiency.
Entry-level charts of the map
They depend on the settings of the software for playback and the driver of the video card. Among the entry-level graphics cards, there are often modern graphics cards, which meanwhile have been replaced by newer models. These are graphics cards that work absolutely smoothly. The price is less than 50 euros. Thus, they are at the bottom of the price and performance segment. They impress less good performance, but rather the added cost of the driver and software compared to the integrated graphics of the chipset.
Today we will talk about such an interesting concept as GDDR5. That this, many do not know, some I can assume, others are aware and understand. In order not to confuse the reader, it is worthwhile to say that GDDR5 is a memory. What it relates to and where it is, we will find out further.
Video memory
In order not to throw out a bunch of terms at once to an ignorant person, it is better to approach from the other side. We all know about the motherboard, which is located in the PC case. It is connected to the processor, power supply, video card, RAM and other elements. In addition to the fact that there is operational memory of the system itself, there is also a similar concept for the video card.
Some games can be played with reduced resolution and less detail. Nevertheless, the pleasure of the game suffers. Because of their low power consumption, they have passive cooling. Average video cards can show most computer games. However, in the case of very complex games, the maximum depth of the part must not be adjusted. This means that you must accept certain cuts in the representation of light and shadow. But only games for medium-class video cards are interesting. By tweaking the graphic parameters, even complex games can be persuaded to display the liquid.
Hence comes the term video memory. In fact, this is the same as RAM, but it is specifically responsible for storing the part of the information that is needed to play the image on the screen. Unlike the RAM of the whole system, this one answers only, roughly speaking, for the video. Therefore, the video memory chips were placed on the video card.
The performance of graphics cards leaves much to be desired. Nevertheless, they are useful only for computer gamers, who can also take a higher power consumption and, therefore, a higher power consumption. High-quality video cards are suitable only for demanding gamers. These are graphics cards that have functions that are unlikely to support the current computer game. In most cases, games for special functions must be programmed. For each external power source, a 450W power supply is required.
Start
Begin acquaintance with different RAM needs from the very first variation. The oldest kind of "RAM" is DDR memory. Now, probably, it is impossible to find motherboards with this type. The operating voltage was 2.5 volts. Naturally, looking back at all types already available, we can safely say that DDR memory consumed the most electricity.
It should be borne in mind that the whole system also consumes electricity. To dissipate the heat waste of these video cards, the graphics cards have cooling structures that occupy two slots of the case. Models with two processors do not double the performance. At best, you can achieve an increase of 50-70 percent.
Compare the performance of graphics cards
Therefore, their use is limited. Graphics cards are often compared based on your functions and functions. Compare the clock frequency, the number of shaders, memory hours, memory bandwidth and graphics memory. Unfortunately, this comparison has little to say about the performance of the graphics card. It would be nice if these performance functions were coordinated to get the best performance. But you do not know this in advance. This means how often the image is recalculated and accumulated.
Variety
Before we learn about what GDDR5 is on the video card, we'll have to sort out the diversity. The type of RAM for all time was countless. To describe each one there is no sense, therefore it is necessary to go directly to the point.
In general, the operative memory device was named DRAM. For the first time it became known to the world during the Second World War. But in its modern manifestation appeared in 1966. For a long time, developers and manufacturers have tried to improve RAM. One of the first types was PM DRAM in the early 90s of the last century. 
In general, we can say that from the frame rate of 30 frames per second is a liquid image. For some games there may be something else. The higher the resolution, the more memory and computing power the screen consumes. Only a combination of resolution and frame rate allows you to compare graphics. For them it is important, for example, that a realistic representation in ego-shooters is smooth. Perhaps you are thinking about getting rid of your old team, which gave you a lot of joys and dislikes. It is true that new machines may be more powerful, but they also assume strong initial investment, and in some respects we will not notice a significant difference.
But the developers had to constantly increase the speed and volume of the "RAM". After six attempts, a new type of DDR SDRAM appears on the market. It began to differ from previous versions with increased data transfer speed (twice). This type was first installed in video cards. Over time, developers decided to use RAM on chipsets.
Perhaps the happiest change you will make. This makes them faster and quieter than usual. If you use it as a system disk and applications, you'll notice that your computer starts much faster, and applications open almost immediately, and in general, everything becomes more fluid.
We used it, very easy to install and cost about 15 euros. From there you get a budget and free compartments of your computer. In recent years, memory has fallen dramatically. The evolution of processors is not so fast in the last five years, as expected. However, the graphics card is impressive. Therefore, many software developers have chosen to rely on the graphics processing power to run their applications' performance. Pay attention to this, since some cards have 8-pin connectors, so they may need more power than our motherboard can supply.
The basis
It is believed that GDDR5 appeared precisely thanks to DDR SDRAM. This fifth version, which was formed for applications. These software required high bandwidth. The predecessor of this option was the memory of the fourth generation. Both were based on DDR3. The communication channel became doubled, buffers appeared at a width of 8 bits.
It is interesting that many manufacturers worked on this type. So in the research "circle" got Hynix, Qimonda, Samsung and JEDEC. Surprise was that they worked with AMD. The work took a very long time, and three years passed from the very beginning to the finish. During this time, the developers managed to achieve excellent results.
We should keep in mind that some of these cards need power, if we want to use hard drives without our own source, so we will need to make sure that there are enough free connectors on our board. These solutions are easily installed by the user. The device has various types of memory and storage options.
Improved memory performance
Media files and some applications can be transferred to this type of memory to free up the internal memory space. The memory of the device often ends as a result of normal use. If the device starts to slow down or the applications suddenly close, you should consider the following.
Then many people learned about GDDR5, what it is and what for. But not everyone could use this memory, since its specifications were still being formed. So at the beginning of its path the chips worked at a low voltage of 1.5 V, while the density was 0.5-2 Gb. Their frequency reached 4000 MHz, and after some time it was possible to raise this figure to 7000 MHz. 
Note that when formatting, all contents of the card are erased. . This will reduce the transmission of your information. But as graphics chips grow faster, their appetite for fast delivery of information continues to grow. Each additional gigabyte per second of bandwidth begins to consume too much energy to be a valid, efficient or cost-effective solution for designers or consumers.
Smaller form factors
The legacy of promoting innovation at the sectoral level
The larger the size, the higher the requirements. It will not be the same to design a house in a lake, a residential building or a skyscraper. As for the operating system and hard disk, the minimum requirements are the same.Already in 2009, a chip with a density of 1 Gbit, a year later - with a density of 2 Gbit. The latter option was formed on a 50-nm process technology. By early 2015, development has led to excellent results. The density of the chip reached 8 Gbit, and the technical process was used at 20-nm. Such a record holder came out under the leadership of the Korean company Samsung.
The theme of the video card is very important. I, without hesitation, recommend that the card be dedicated, not integrated. That is, she has her own memory, designed only for the card. Although this is very important, it's even more of a graphics chip. You will need a powerful one. The speed of the card depends mainly on this chip.
Workstation components achieve new levels of performance, while ensuring reliability, compatibility, scalability and an improved architecture, ideally suited for multi-processor environments. There are several specifications on the video card that make the difference. To not regret it later, it is very important to understand some concepts before you make a purchase. One of these functions is the type of memory used.
Specification
To learn more about GDDR5, what it is and what this memory is for, it is important to consider the main characteristics that are now used by all manufacturers. As it became clear, in the title the letter "G" is responsible for the concept of Graphics. That is, this type of memory is needed for the operation of the video card.
GDDR5 was released agreed standardization. Under the control of 8n architecture, with the interface of the dynamics configuration, as well as with technologies that allowed to increase the speed. One chip has a bit capacity of 32 bits and a case has 170 contacts. The process technology is 40 nm.
Know the differences and know which is the best option for you. There are additional differences that directly reflect the quality of the schedule provided by the models. This is due to a number of factors, such as synchronization data, latency and lower bandwidth.
In addition, it can operate at higher frequencies, which increases throughput. The highlight is the error correction code, which allows you to increase the frequency of operations. With a higher price, it can be useful for those who have a very limited budget, anyway, if everything works as much as possible and does not want to spend too much.
The frequency can be determined by two factors. If the first shows a value of 1250 MHz, then the second will be 2500 MHz, that is, twice as much. Manufacturers often indicate different frequencies, but the transmission rate itself will always be the same. 
The main advantage of the new product is improved throughput. Unlike the third generation of video memory, the fifth began to work on a bus with a width of 128/256 bits. In many ways it helped to save on some indicators. So, in GDDR3 used 512 bits for the bus. This indicator increased the size of the chip, its packaging, and therefore the cost of the entire model. Video cards with this type consumed more energy.
Models can be an option for those looking for better performance and games from past generations in a good configuration. This is one of the factors that hinders the development of high-performance platforms, because, despite the powerful powerful graphics chipset, performance will be severely penalized by slow access to shared memory.
There are not many secrets about how to increase throughput using memory on a video card. Extending the bus is always the safest option, since the performance gain is directly proportional to the number of data paths without any significant changes. When doubling the number of tracks, the transmission speed doubles, without side effects in terms of performance.
Introduction
Now we know about GDDR5, that this video memory, over which the leading manufacturers worked. Not surprisingly, the first model of the video card appeared in 2008 from AMD. It was ATI It was presented in two variations, which differed in volume: 512 MB and 1 GB.
There were also models from Nvidia Geforce. GDDR5 appeared immediately in a whole series of cards, among which were: GTX 550, GTX 560, GTX 580, GTX 590, GTX 660, GTX 680, etc. In addition, this type of memory is also found in the fourth version of the PlayStation console. At the same time it was put here as RAM.
The big problem is that using more tracks makes the board production much more expensive, affecting several stages of production. To complicate the situation, additional tracks and chips also increase power consumption, which further complicates the project.
A good example of the difficulties in designing boards with 512-bit buses is the case. Because of all these problems, manufacturers are rather cautious about wider tires, preferring to use fast chips when possible. Then we turn to the second possibility, which is to use faster memory chips that carry not only modules supporting higher frequencies, but also between different memory technologies.
conclusions
Summarizing all of the above, it is important to understand that it took a long time after the RAM appeared. Video memory developed and formed. Now the fifth generation is not the fastest among all. Relatively recently, another type became known - GDDR5X. It's twice as fast. Nevertheless, GDDR5 is the most popular memory, not only as a component of the video card, but also as stand-alone RAM chips. 
Just like when overclocking memory through the setting, increasing the voltage allows the modules to support higher frequencies, but in turn increases consumption and electrical dissipation, resulting in a configuration that is far from ideal.
Despite modesty, these improvements led to a significant increase in the frequency of the chips. One of the main improvements is the restoration of the clock data, which functions as a learning function, which allows the controller to detect small differences in the synchronization between the signals of different contacts, which greatly simplifies the use of higher frequencies and weakens the characteristics along the length of tracks.
Now the main threat that can contribute to the disappearance of this type of memory from the market is that memory has nowhere to develop and improve. In addition, it has not yet been possible to solve the problem with high energy consumption. And although the values relative to previous versions have become much smaller, it still does not solve anything. In addition, given the recent tendency towards overclocking, the problem with increased power consumption is urgent and acute.
Another important feature is the protocol for detecting read and write errors, which greatly increases the tolerance range of the modules to various errors, since the chipset can simply repeat operations when necessary. The error rate increases with the operating frequency, so higher frequencies can be achieved with a higher tolerance level.
In conclusion, we have an old discussion about the amount of memory on the board. To store textures, vertices, and other information needed to compose an image, video memory is required. Of course, using more memory allows you to include better parameters and does not allow graphics cards to lose performance using system memory. However, at a certain point, adding more memory does not affect the performance of the board, simply because the excess will not be used.
Video card (graphics card, video adapter) - A device that converts an image that is stored in the computer's memory into a video signal for the monitor.
A video card is undoubtedly a very important component in the system unit. It displays the image on the screen of your monitor. And the better the video card - the faster and better this image will be displayed (in particular, in games). So if you plan to not only read mail and work with Microsoft Word, then we do not recommend saving on a video adapter.
Let's start with video cards, integrated (embedded) in the motherboard. It is not recommended to buy such solutions. Exceptions are only cases where money is not enough for a normal video accelerator, and the computer will be used only for work (office applications, work with text, the Internet, etc.) or for example, only to listen to music, tk. it does not require a powerful video adapter. The thing is that the performance of integrated graphics cards is very, very low. In addition, such cards take up a lot of RAM (because they do not have their own) and heavily load the CPU of the computer.
Let's consider discrete (not integrated) video cards in more detail.
Now on the market there are two manufacturers of discrete graphics processors - NVIDIA and ATI / AMD. Note that the companies themselves do not sell video cards - these are their partners (such as ASUS, Gigabyte, MSI, etc.).
Brief about tires
In the early 2000s, the video cards mainly used the AGP bus to connect to the motherboard.
AGP (from the English Accelerated Graphics Port) - Developed in 1997 by Intel, a specialized 32-bit system bus for a video card.
Then the public was introduced a new, more productive bus - PCI Express.
PCI Express - A computer bus using the PCI bus software model and a high-performance physical protocol based on serial data transmission.
Note that the video cards do not have backward compatibility with the tires. Those. You can not insert a PCI-E video card into an AGP slot, and vice versa.
We will not consider video cards running on the outdated AGP bus, because they have more modern analogs on the PCI-E.
What should I look for when choosing a video adapter:
1. Graphics processor (GPU, video processor, chip, core) *. The older the series, the more modern the graphics card and the more new technologies in the field of computer graphics it supports. It should be noted that performance is not directly dependent on the graphics processor series. For example, the NVIDIA GeForce 8500 graphics card is less productive than the NVIDIA GeForce 7900 graphics card. Similarly, the ATI Radeon HD2600 graphics card is "weaker" than the ATI Radeon X1950.
* Graphic processor (English Graphics Proccesing Unit, GPU) - A separate device of a personal computer that performs processing of graphic data. Thanks to a specialized pipeline architecture, modern GPUs are much more efficient at coping with the task of processing graphics information than the CPU.
GP in modern video adapters is also used as an accelerator of three-dimensional graphics. Distinctive features (in comparison with the CPU) are:
1) The architecture, aimed at maximizing the speed of the calculation of textures, physical effects and complex graphic objects.
2) Limited command set.
2. The amount of video memory *. Then everything seems to be clear. The more memory - the better. Although this statement is not always true. For example, it makes no sense to buy a graphics card with a weak graphics processor, but with a large amount of video memory.
* Video memory - memory in which the image displayed on the monitor screen is stored. It can be of several types.
3. Type of video memory. In modern graphics cards of the budget class, GDDR2 memory is still installed, but in more expensive solutions, GDDR3 (sometimes GDDR4) is used. Many video cards already have GDDR5 memory installed. Naturally, gamers recommend video cards with a memory type of at least GDDR3.
4. The width (width) of the memory bus. It is measured in bits and in modern maps it is from 64 to 512 bits. The higher the number of bits, the more bandwidth the graphics card has. This is a very important parameter in the performance of the video adapter. However, AMD was the first to break this principle by releasing Radeon HD 5xxx series video cards. Some models of video cards in this series use GDDR5 memory with a bus of only 128 bits, but in performance these video accelerators are not inferior to boards with GDDR3 memory and a bus width of 256 or more bits. As the high memory speed GDDR5 compensates for the small width of the bus.
5. Availability of support for SLI * (NVIDIA) or CrossFire * (ATI). If you plan to install 2 or more video cards in the SLI or CrossFire mode, you should check whether the video cards you are buying support this mode. At the moment, among modern graphics accelerators there are no models without the support of this or that mode.
* SLI (Scalable Link Interface) - a technology that allows you to use the power of several graphics cards to process 3D images. Developed and used by NVIDIA.
For the assembly of the SLI-system, in addition to the main components, it is required:
1) A motherboard with two or more PCI Express slots that supports SLI (on the NVIDIA chipset, Intel X58 or Intel P55).
2) Powerful power supply.
3) GeForce 6/7/8/9 / GT200 / GT400 or Quadro FX graphics cards with PCI Express bus.
4) A bridge that combines video cards (usually comes bundled with video cards).
Video cards must belong to the same class. Those. they should be on the same chips (you can not combine SLI video cards, for example, GeForce 8800GTX and 8600GT). In this case, the motherboard manufacturer does not matter.
Conjugation of video cards in SLI-mode can be provided in two ways:
1) Using a special physical bridge.
2) Programmatically.
In the latter case, the load on the PCI Express bus increases significantly, which negatively affects the performance of the video subsystem.
The systems of Quad SLI and Tri-SLI have spread. In the first case, it is supposed to combine two dual-chip (dual-core) cards into the SLI-system. Thus, it turns out that 4 chips are working in the construction of a three-dimensional image. In the second case, 3 single-chip (single-core) cards are combined.
* CrossFire - a technology that allows you to simultaneously use the power of two or more video cards of the Radeon model to build a 3D image. Developed and used by ATI / AMD.
To build a system with CrossFire, you must have:
1) Motherboard with two or more PCI Express x16 slots with AMD or Intel chipset (make sure that it supports CrossFire mode when purchasing the motherboard).
2) Powerful power supply.
3) Video cards with CrossFire support.
Video cards should be the same series, but not necessarily one model (that is, the boards can be on different chips). In this case, the speed of the CrossFire system is determined by the characteristics of the core of the least productive video card.
The work of CrossFire can be provided in three ways:
1) External connection - video cards are combined with a special cable. In this case, the card on which the special chip "Compositing Engine" is decapitated is called the "Master Card". The remaining video cards can be any within the series.
2) Internal connection - video cards are connected using a special flexible bridge (similar to the SLI bridge). The driver determines which one will be the master card.
3) Software way - video cards are not physically connected, and data transfer is via PCI Express x16 bus, and video card interfacing is done programmatically, using drivers. A major drawback of this method is the loss in productivity by 10-15% compared to the two previous methods.
CrossFire mode is supported by almost all modern motherboards having two or more PCI Express x16 graphics card slots (with the exception of NVIDIA chipset cards).

They can include descriptions of absorption, reflection, refraction and scattering of light, texture mapping, surface displacement and post-processing effects. For example, shaders are used for realistic drawing of water surfaces.
* Effective memory frequency. Because DDR memory is installed on video cards, then data is transmitted 2 times in a single clock cycle. Hence the doubling of the frequency. This value is called the "Effective Frequency". For example, the memory operates at a physical frequency of 200 MHz, and the effective frequency in this case is 400 MHz.
