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.
Video cards for rendering
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:
- They are able to process a given model at high speed;
- To speed up the process, it is possible to install several of them into the system at once.
The disadvantages include:
- Each video card has video memory limits;
- The current prices for good cards are prohibitive due to the mining hysteria.
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.
Video cards for video editing
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.
Separation of cards by types
Professional Models
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.
Consumer Models
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 from Nvidia
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.
Professional (QUADRO) and gaming (GeForce) acceleration technologies in Nvidia cards
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:
- For corporate clients who are ready to bear very high costs for professional equipment;
- For those who need a large amount of video memory, who need the ECC memory function, as well as increased color depth and high accuracy of working with floating point (floating point operations);
- For those who work only with exclusive and professional software;
- Who constantly uses the support of a software developer to solve work problems;
- Those who need guaranteed reliability of server solutions.
GeForce technology will be preferable in cases:
- Application of a video card for everyday tasks (games and simple graphic work);
- There is no need to use ECC memory;
- It is required to get maximum performance for a relative minimum of money;
- No vendor software support required;
- The operation of the video chipset is mainly focused on the gaming component.
Ray tracing on graphics cards (RTX technology from Nvidia)
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.
Selection Options
When purchasing a video card, you should pay attention to the following technical points:
- Type and amount of video memory - today a card with a capacity of less than 1 GB simply will not be quoted. The memory type must be at least GDR5 - it will be relevant for the next two to three years. This is about equipment for everyday tasks. If professional activity is supposed, then the choice should be made in favor of a model with a large amount of memory and in which the latest technologies are used to speed up the calculation of a three-dimensional scene;
- The number of CUDA cores - as a rule, this parameter will be important for working with any three-dimensional graphics. Although, practice shows that the indicator for this parameter is more important for professional work than for games. Indeed, this technology can speed up the calculation of a three-dimensional model by 10-50 times (depending on the total complexity of the scene, its static parameters, or if there is movement in the scene, then it will be necessary to calculate the physics of objects, which will slow down the rendering process);
- Connection type and power consumption - not all video cards can fit the existing motherboard. Before buying, be sure to check the compatibility of these two components of the computer system. The standard today is the type of bus on the motherboard PCI-E x16 version 3.0. It's always worth remembering that many models of modern cards are quite bulky and in most cases will occupy two slots at once, which will create additional questions for the cooling system of these elements. Accordingly, the purchased card must be suitable not only in terms of technical parameters, but also in terms of its dimensions. In addition, it is worth considering that in the future it may be necessary to increase the graphics power, for which you will have to install an additional second video card. Nvidia calls this option SLI (Scalable Interface). From this it is clear that the motherboard must again support not only the technical ability to work with two video cards at once, but also have the appropriate number of connectors for connection (although it is possible to use adapters). However, for several video cards, the power of the power supply (and the connectors for connecting to it) may well not be enough;
- The need to expand the power supply of the computer - in principle, any computer on which it is supposed to do professional three-dimensional modeling should be reliably supplied with power. Some manufacturers of video cards especially focus on this circumstance. So, a 550W power supply is already the “last century” and will hardly be suitable for the work in question.Thus, it is not worth saving on this parameter and it is better to buy a massive system unit with a powerful power supply unit from 600W for a decent price than trying to find something cheaper with similar parameters. It should be recalled that most Chinese manufacturers producing system units often complete them with weak power supply modules, despite the fact that they indicate an indicator of 550W or more in the technical information. In fact, such models are quite cheap, and the power of their power supplies is unlikely to actually exceed 450W;
- Type and number of interfaces for output - this parameter means how many monitors can be connected to the video card and through which connectors. In our time, cards that are connected only via the SVGA connector and that have the ability to connect only one device for display have already sunk into oblivion. The standard is to connect at least two monitors, and the standard for connecting them to the card is HDMI technology;
- Maximum resolution - any modern card must support a minimum resolution of 4K (3840x2160 pixels). However, for professional work, you will need 8K resolution (7680x4320 pixels). Although, for games, Full HD - 2K (2048 × 1024 pixels) will be enough;
- Bus frequency and bit width - these parameters are a "concern" only for professionals, although it should be noted that the higher these indicators, the better the performance of the video card will be (naturally, which will simultaneously increase its cost).

Instead of an epilogue
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.
