The concept of rendering a three-dimensional (3D) model implies its calculation and visualization in virtual space. Such a calculation is associated with the display of shadows and colors of the object, the texture of its surface, the observance of shapes and dimensions. To display the model on the screen, a special program must combine all the data entered by the user, taking into account the camera angle, and take a picture. The combination of these processes, called rendering, is extremely demanding on a computer system. Traditionally, all this was done through the central processor, but today special programs (graphic editors) “transfer” part of the calculations to the video card. This method significantly offloads the system as a whole and is faster.

On the graphics processor of a video card, the calculation is much faster, because this is their main purpose. For example, a $400 graphics card will render a scene faster than a powerful $3,500 22-core CPU.
Modern rendering graphics cards have the following advantages:
The disadvantages include:
If the RAM for the system as a whole can be increased to a certain size, then this method is not suitable for a graphics card. How many chips are soldered at the factory, so much video memory will always be on the card - this memory cannot be reduced or increased. Video memory, of course, is faster than RAM, because. not occupied by many third-party processes. However, it is impossible to manage only with a large amount of memory on the carriage, the processing speed will also depend on the power of the graphics processor installed on it.
Several video cards can also be used without a scalable interface (the mode of operation of two or more video cards on one task). The absence of such a mode will allow you to use the computer in normal mode through one video card, while the second (the rest) are working on rendering the scene.
IMPORTANT! If the motherboard allows, then it is possible to attach up to 6-7 video cards to it through adapters.
Naturally, the video editing process is somewhat less demanding on the video card than the calculation of three-dimensional models. If you need to edit not very complex videos, then the model from Nvidia with CUDA support is enough. They will do just fine for most tasks in the Premiere Pro editor. It should be noted that photo and video processing does not require a powerful video device, especially with QUADRO technology. For these purposes, an average sample with a ray tracing mode is quite suitable. However, if you work with video in 4K / 8K modes, you may need a more expensive version.
Their main difference from consumer goods is the support of various software (SW).AMD FirePro or Nvidia Quadro series cards are specifically designed for increased performance when working with special programs and have the highest guaranteed compatibility with profile editors from leading software developers. Among other things, professional models are diligently supported by software developers for a long time, which makes this technique a good investment. It is worth mentioning that samples of the professional segment are thoroughly tested in the corresponding software, and individual versions of such software will not work at all if they do not find the specially designed hardware they need.
At the same time, some software developers will simply refuse to resolve problems and support if they find out that their software worked with hardware that was not intended for it. This situation may well become an insurmountable difficulty if a large amount of work is required to be completed in a certain period of time, which will mean a clear loss of income, i.e. lost business profits.
Such options can perfectly manifest themselves in solving everyday problems or in gaming applications. They are quite capable of producing good results when processing photos or video editing, and some models (for example, the RTX 2080Ti) are completely overpowered for such work. The same models will show good results in game rendering, but they lack the features that are necessary for professional 3D modeling. Consumer variations, in principle, are suitable for games and video or photo processing at good speed, but they lack the necessary amount of video memory to work in specialized applications for 3D modeling.

CUDA cores are special computing cores that are part of the Nvidia graphics card lineup. This technology is exclusive and is presented only in the products of this company. In principle, it is not a dedicated element only for graphics processing, but rather represents a kind of universal power that the video chip can use to process various tasks as needed. Most modern software designed to work with graphics has already been adapted to make the most efficient use of these cores, so the more of them there are on the video chipset, the faster the models will be rendered.
For example, the most popular and modern rendering algorithms, such as Redshift and GPU Octane, are generally completely CUDA-oriented, which means that they will only work with the use of appropriate cards from Nvidia. It is in these software algorithms that one can clearly see the linear increase in rendering speed depending on the number of CUDA cores on the video card.
IMPORTANT! It is worth noting that the popular editors Premier Pro and After Effects support both AMD and Nvidia cards, but processing is faster on the latter.
Through GeForce technology, you can get more benefits in terms of price and speed, but only if you intend to use the card for games, video editing, or simple graphics processing. From this it is clear that this technology is aimed at the gamer market and therefore these video cards lack many of the special features that are required for professional graphics work.
In turn, QUADRO has a higher level, but it is more focused on supporting corporate users. If we compare this technology with the previous one, then the replacement of each new video card will cost a considerable amount. QUADRO should be used if there is a 100% need for ECC memory (error correcting memory). It is worth noting that these cards will always have a larger number of CUDA cores in their structure. As a result, the cards in question will fit:
GeForce technology will be preferable in cases:
Nvidia introduced a line of new ray tracing cards at the time of the introduction of the Turing architecture. These cards, coupled with CUDA cores, have RT cores and a tensor core that do ray tracing.In 3D calculation, a tracing-enabled card can significantly increase the speed of operations, especially in programs that support this technology. But tracing will not help simple video editing in any way, because in this case work occurs exclusively with a two-dimensional image.
The core tensor (in consumer graphics cards) is responsible for various effects, for example, for creating sampling (samples) based on deep learning of neural networks, with the help of which AI (artificial intelligence) is able to change / improve the quality of the picture.
When purchasing a video card, you should pay attention to the following technical points:
This Taiwanese-made product is notable for its size (occupies three slots) and massiveness. Equipped immediately with two fans, because it requires intensive cooling. Also, additional power will be required, which will be received from the PCI-E 16x 4.0 bus. Initially, the model was focused on professional calculations, but it also showed itself well in the gaming field. Due to its sufficient computing component, it has gained a certain amount of popularity among cryptocurrency miners. The math block is characterized by 2304 universal processors, 144 texture units, 64 rasterization units. DirectX 12 and OpenGL 4.6 are supported. Operates at a frequency of 1610 MHz. The device supports simultaneous connection of up to 4 monitors. Can provide a maximum resolution of 7680×4320 thanks to 8GB of video memory - type GDDR6, frequency 1.4GHz with 256-bit bus. Processor - AMD Radeon RX 5700. SLI/CrossFire supported. The active connection interfaces are three DisplayPort 1.4, one HDMI 2.0b, HDCP is supported. The recommended cost is 53,000 rubles.

This model is made in North America and is considered objectively the best consumer model. The manufacturer does not indicate its overall dimensions, but it occupies only one slot. She has at least one fan, but it is active, which indicates a small indicator of heating during operation.It is characterized by good optimization of all functional processes. The device supports simultaneous connection of up to 4 monitors. Established interfaces - four DisplayPort 1.4. There is HDCP support. The kit includes adapters for other types of interfaces, but professionals confidently criticize them and recommend replacing them with more up-to-date ones. The maximum supported monitor resolution is 5120×2880. The card is based on the GP106GL graphics chip, created using the 16nm process technology. Connects to the motherboard via a PCI-E 16x 3.0 slot and does not require additional power. The amount of installed video memory is 5 GB of GDDR5 type on a 160-bit bus. Supports DirectX 12, OpenGL 4.5, OpenCL 1.2, CUDA 6.1, Vulkan technologies. Consumers report improved performance in some software (such as SolidWorks). It can be useful in design activities, because it perfectly displays the pre-rendering image (objects without textures), works well with two-dimensional graphics in 4K resolution. The recommended cost is 63,000 rubles.

The video card supports up to two monitors. Regular interfaces - two DisplayPort, one DVI-I and even VESA Stereo. The maximum possible monitor resolution is 2560×1600. The card has 2GB of video memory. Memory type - GDDR5, operates at a frequency of 3GHz. The memory bus is 320-bit. RAMDAC frequency - 400 MHz.Built-in full support for SLI/CrossFire.
This model has 352 arithmetic logic units, the fifth version of shaders, 16x anisotropic filtering. Limiting degree FSAA - 64 times. Like all modern video cards, the PNY Quadro 5000 has built-in support for OpenGL 4.0 and DirectX 11. Against the background of the above models, the characteristics of the PNY Quadro 5000 may look “poor”, but, again, in combination with a discrete accelerator, this model is capable of a lot, like in terms of creating the most complex polygonal 3D graphics, and for extremely complex calculations.
It is built on the basis of the eponymous graphics processor from nVidia, codenamed GF100 (clock frequency - 513 MHz). Manufactured in 40nm process technology. Connects to motherboard PCI-E 16x 2.0 slot. Although the technical process here is a generation older, compared to some neighboring models, the chip heats up moderately - at the level of 152 watts. The card needs additional power, for this a 6pin connector is provided. The recommended cost is 120,000 rubles.

Although this device is characterized by relatively moderate power consumption, it still does not have enough power that it receives from the slot to work.Therefore, to connect additional electricity, it has two sockets 8 pin and 6 pin. The installed amount of RAM is 16384 MB, the memory type is GDDR5 on a 512-bit bus. The memory is "fast" - operates at a frequency of 5 GHz. Bandwidth - 320 Gb / s. At the heart of this graphics accelerator is the powerful FirePro S9150 processor of the same name manufactured by AMD, codenamed Hawaii XT. Created on the 28nm process technology. Capable of generating up to 5.07 teraflops of processing power. In terms of one watt of power consumption, the video card produces 21.6 gigaflops, and this is a record value in this class. The mathematical module of the video card is characterized by 2816 universal processors, 176 texture units, 64 rasterization units, and the fifth version of shaders. OpenGL 4.4 and DirectX 12 are supported. The recommended cost is 118,000 rubles.

This map can be called the center of mathematical calculations. Such a device needs to be paired with a video card (Tesla works best with professional video cards of the Quadro family), and then the graphics stream will go through the video card with all the expected amazing effect in terms of performance, speed, stability. So you can get a "monstrous", in the best sense, computing power of 3-3.5 teraflops at home.
The basis of the video card is the Tesla K40 graphics processor of the same name, codenamed GK110B manufactured by nVidia. Manufactured according to the 28 nm process technology.Operates at a frequency of 745 MHz. The processor architecture contains 2880 arithmetic logic modules. The graphics accelerator supports DirectX 11.2 technology. It has 12GB of GDDR5 RAM. The memory is "fast" - it operates at a frequency of 6 GHz, the bus is 384-bit. Implemented support for SLI/CrossFire. Of course, such solutions are simply blasphemous to use for computer games. The destiny of PNY Tesla K40 is the processing of high-quality video material in 4K resolution or even higher, but to a greater extent - the most complex calculations within the framework of deep learning. For rendering complex 3D graphics in Maya, 3ds Max and similar tasks, it is better to look at another model. The recommended cost is 200,000 rubles.

The processor is built on the Turing architecture, its code name is TU102. Created using a super-thin 12 nm process technology. Operates at the stock clock frequency of 1.44 GHz. The mode of regular acceleration of the processor is supported within the framework of Boost technology up to 1.77 GHz. It has 24 GB of RAM installed. The most advanced memory type today is GDDR6. The memory bus is 384-bit. The memory runs at an unprecedented speed of 14GHz and delivers up to 672GB of bandwidth per second. Such exorbitant power, of course, requires additional power. For this, the card itself has two sockets - a 6-pin and an 8-pin. To connect monitors, the card provides 4 DisplayPort interfaces, and in addition there is a USB Type-C port.Translating all these parameters into a more applied language, we can say that the video card, combined with everything else with adequate hardware in the computer, is capable of providing a texturing speed of up to 509.8 gigatexels per second. Physically, the video card is 267 mm long and plugs into a PCI-E 3.0 x16 motherboard slot. The recommended cost is 400,000 rubles.

The analysis of the market of the devices under consideration found that its biggest problem is the extremely high prices for equipment. This situation has developed against the backdrop of hysteria in the field of cryptocurrency mining, which is why it is not always possible to purchase even very expensive models. Regrettably, this situation tends to persist.
