Knowing the GPU model, you can find detailed information on it (special specs, reviews, reviews, etc.) and evaluate how suitable this board is for your purposes. It is worth noting that in video cards from third-party brands, the characteristics of the graphics processor may differ slightly from the standard ones (and often in the direction of acceleration and improvement).

A set of properties and qualities inherent in a whole family of video cards. The GPU architecture is designed for massively parallel computing to efficiently handle computer graphics processing.

Modern video cards are built according to one of several common architectures:

Turing. The NVIDIA Turing architecture debuted towards the end of 2018. It is named after the English mathematician Alan Turing. Turing has pioneered ray tracing RT cores that accelerate light and sound motion calculations in a 3D environment by up to 10 billion rays per second. Also, the architecture is equipped with tensor cores, a new multi-threaded processor and a unified cache architecture with double the bandwidth (compared to previous generations). Used by Turing in GeForce RTX, Quadro RTX and Tesla T4 graphics cards.

Ampere. The second generation RTX architecture that replaced Turing in 2020. It is named after the French physicist and mathematician André-Marie Ampère. The architecture marked the rise of the NVIDIA GeForce RTX 3000 series gaming graphics cards. Ampere introduced new streaming multiprocessors, second edition RT cores, and third generation tensor cores. The key point of these improvements is not only an increase in raster performance, but also a reduction in the load when calculating rays. The Ampere architecture is found in the GeForce 30 family of...GPUs from NVIDIA.

Ada Lovelace. Launched in 2021, the Ada Lovelace family of GPUs features new 3G RT cores that provide 2x performance gains with ray tracing. The architecture also uses fourth-generation tensor cores, which are up to two times faster in AI training operations, and CUDA cores, which are twice as productive in single-precision operations compared to previous generation solutions. The architecture is implemented in NVIDIA GeForce 4000 and 6000 series video cards.

Navi (RDNA). The first graphics solutions from AMD based on the Navi RDNA architecture were released in the summer of 2019. Having half the area of the chip, it managed to accommodate the same 12.5 billion transistors as in the previous generation of chips on Vega 10. Video cards based on the Navi architecture (RDNA) video cards have increased energy efficiency and performance, especially in games. The debut of the architecture took place in the graphics cards of the Radeon RX 5700 line.

Big Navi (RDNA 2). Big Navi Architecture (RDNA 2) has been on the move since 2020. She got improved computing units, an improved graphics pipeline and a new high-speed cache memory AMD Infinity Cache. The architecture demonstrates high levels of energy efficiency and performance. In particular, compared with the first edition of RDNA, the increase in performance per watt was up to 54%. Also, Big Navi has improved hardware devices for ray tracing (Ray Accelerator), which provides more realistic rendering of graphics in demanding games. The architecture is used in AMD Radeon RX 6000 series video cards and top gaming consoles (Sony PlayStation 5, Xbox S/X).

Navi 3X (RDNA 3). Changes in the third edition of the RDNA architecture are aimed at comprehensively improving gaming performance at high resolutions of 4K and 8K. RDNA 3-based GPUs are the first multi-chip GPUs from AMD. Redesigned compute units and second-generation AMD Infinity Cache technology deliver up to a 54% performance boost when compared to the previous generation Big Navi Navi 3X. There are also improvements in ray tracing performance - the corresponding blocks can count on 50% more rays per clock. The architecture has found application in gaming video cards of the AMD Radeon RX 7000 family.

The amount of own memory of the GPU; this parameter is sometimes called the amount of graphics card memory. The larger the amount of GPU memory, the more complex and detailed picture it is able to process in a period of time, and therefore, the higher its performance and speed (which is especially important for resource-intensive tasks like high-end games, video editing, 3D rendering, etc. ).

When choosing, it is worth considering that the performance of a graphics card is affected not only by the amount of memory, but also by its type, frequency of operation (see below) and other features. Therefore, situations are quite possible when a model with less memory will be more advanced and expensive than a more voluminous one. And you can unambiguously compare with each other only options that are similar in other memory characteristics.

On the modern market, there are mainly video cards with memory capacities of 2 GB, 4 GB, 6 GB, 8 GB, 10 GB, 11 GB, 12 GB, and 16 GB or even more can be installed in the most advanced models.

The amount of data (bits) that can be transferred over the graphics card's memory bus in one cycle. The performance of the graphics card directly depends on the bus width: the higher the bit width, the more data the bus transfers per unit of time and, accordingly, the video memory runs faster.

The minimum bit depth for modern video cards is actually 128 bits, this figure is typical mainly for low-cost models. In mid-level solutions, there are indicators of 192 bits and 256 bits, and in advanced models — 352 bits, 384 bits and more, up to 2048 bits.

The frequency of the graphics processor of the graphics card. As a general rule, the higher the frequency of the GPU, the higher the performance of the graphics card, but this parameter is not the only one — a lot also depends on the design features of the graphics card, in particular, the type and amount of video memory (see the relevant glossary items). As a result, it is not unusual for a model with a lower processor frequency to be more performant of two video cards. In addition, it should be noted that high-frequency processors also have high heat dissipation, which requires the use of powerful cooling systems.

The result shown by the graphics card in the test (benchmark) Passmark G3D Mark.

Benchmarks allow you to evaluate the actual capabilities (primarily overall performance) of a graphics card. This is especially convenient in light of the fact that adapters with similar characteristics in fact can differ markedly in capabilities (for example, due to the difference in the quality of optimization of individual components for joint work). And Passmark G3D Mark is the most popular benchmark for graphics adapters nowadays. The results of such a test are indicated in points, with a higher number of points corresponding to better performance. As of mid-2020, the most advanced graphics cards can score over 17,000 points.

Note that Passmark G3D Mark is used not only for general performance evaluation, but also to determine the compatibility of a graphics card with a specific processor. The CPU and graphics adapter must be approximately equal in terms of the overall level of computing power, otherwise one component will “pull back” the other: for example, a weak processor will not allow a powerful gaming graphics card to unleash the full potential. To search for a video adapter for a specific CPU model, you can use the list "Optimal for AMD processors" or "Optimal for Intel processors" in the selection of our catalog.

The number of HDMI outputs provided by the graphics card.

HDMI is by far the most popular interface for high-definition video and multi-channel audio (it can be used for video and audio at the same time). This connector is almost standard for modern monitors, in addition, it is widely used in other types of screens — TVs, plasma panels, projectors, etc.

The presence of several outputs allows you to connect several screens to the graphics card at the same time — for example, a pair of monitors for organizing an extended workspace. However, there are never more than 2 HDMI ports in video cards — for a number of reasons, for several screens at once, in this case it is easier to use other connectors, primarily DisplayPort.

HDMI interface version supported by the graphics card. For details about HDMI itself, see above, and its versions can be as follows:

— v.1.4. The earliest HDMI standard found in video cards; was introduced in 2009. Despite its “venerable age”, it has good capabilities: it supports 4K video (4096x2160) at a frame rate of 24 fps, Full HD (1920x1080) at a frame rate of up to 120 fps, and is also suitable for transmitting 3D video.

— v.1.4b. The second improvement of the above v.1.4. The first update, v.1.4a, introduced support for two additional 3D video formats; and in HDMI v.1.4b, mostly minor improvements and additions to v 1.4a specifications were implemented, almost imperceptible to the average user.

— v.2.0. Standard introduced in 2013 to replace HDMI v.1.4. Thanks to its full 4K support (up to 60 fps), it is also known as HDMI UHD. In addition, there is enough bandwidth for simultaneous transmission of up to 32 audio tracks and up to 4 separate audio streams, and the list of supported frame formats has been replenished with ultra-wide 21:9.

— v.2.0b. The second update of the HDMI 2.0 standard described above, which differs primarily in HDR support. However, HDR compatibility itself appeared in the first update, v.2.0a; and version 2.0b added the ability to work with HDR10 and HLG standards.

— v.2.1. The newest common HDMI standard released in 2017. Capable of providing a frame rate of 120 fps in ultra-high resolu...tion video signal — from 4K to 8K inclusive; some improvements related to the use of HDR were also provided. Note that all the features of HDMI v.2.1 are available only when using cables marked Ultra High Speed, although basic functions work through ordinary cables.

The number of DisplayPort outputs provided by the graphics card.

DisplayPort is a digital media interface similar in many ways to HDMI, but primarily used in computers. The specific capabilities of this interface depend on the version (see below), but even in the most modest modern version of DisplayPort, it allows at least 4K at 60 frames per second and 5K at 30 fps. Another interesting feature of this standard is the ability to daisy-chain multiple screens to one port (“daisy chain” format).

In light of the latter, we can say that the number of DisplayPort outputs corresponds to the number of screens that can be connected directly to the graphics card, without using a daisy chain. Such a connection may be required, in particular, for monitors that do not support daisy chaining. If such a mode is supported, the maximum number of screens will be at least twice as high as the number of connectors. However, it is worth considering that the resolutions supported by the video adapter itself may not reach the maximum capabilities of the DisplayPort version used.
