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).

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 type of graphics memory used by the graphics card (see GPU memory capacity). To date, the following types of memory are used:

— DDR3. General purpose RAM that is not specialized for graphics processing and was originally designed for use in the general system RAM. However, due to good performance and relatively low cost, it has recently been used in video cards (albeit, mainly at a low-cost level).

— DDR4. Further, after DDR3, the development of general-purpose RAM. Specifically, it is extremely rare in video cards, due to the prevalence of more advanced specialized standards.

— GDDR2. The second generation of memory built using Double Data-Rate technology (“double data transfer rate”). In fact, it is a modification of DDR2 RAM, optimized for use in video cards; just like the original DDR2, it provides 4 data transfer operations per cycle (original DDR — 2 operations). It has not received wide popularity due to the tendency to strong heating during operation.

— GDDR3. Improved version of GDDR2 (see above). It has a higher effective frequency (as a result, performance), while differing in lower heat dissipation. Some time ago it enjoyed considerable popularity, now it is gradually falling into disuse, giving way to more advanced standards.

— GDDR5. Pretty advanced video memory format; unlike earlier versions of GDDR...(see above), it is based on DDR3 RAM.

— GDDR5X. A further enhancement to GDDR5 memory designed to increase bandwidth (and thus overall speed and graphics performance). Various design improvements made it possible to achieve a 2-fold increase in maximum speed — up to 12 Gbps versus 6 Gbps for the original GDDR5. At the same time, although GDDR5X is inferior in terms of characteristics to HBM (see below), it is also much cheaper.

— GDDR6. Further, after GDDR5X, the development of GDDR-type graphic memory. Achieve data rates up to 16Gb/s per pin, nearly double that of GDDR5, at a lower operating voltage. Such characteristics allow the use of GDDR6 to work with 4K resolutions and higher, as well as virtual reality systems; video cards with such memory are mainly classified as top-end solutions.

— GDDR6X. An improved version of GDDR6 released in Fall 2020. According to the creators, it is the fastest graphics memory at the time of release. One of the key updates is the use of the so-called multi-level PAM4 modulation, which allows you to transfer 2 bits of data per cycle (versus 1 bit for its predecessors). Due to this, the bandwidth of GDDR6X can reach 21 Gbps per pin and 1 TB / s for the entire memory block (versus 16 Gbps and 700 Gbps, respectively, in the previous version). This type of memory is great even for the most powerful modern video cards, but it also costs accordingly.

— HBM. A type of memory designed to maximize throughput. It differs fundamentally from various versions of GDDR in that the HBM module is built on the "sandwich" principle — the memory chips in it are placed in layers and allow simultaneous access; and for communication with the processor, a special silicon layer is used, the so-called "interposer", which provides efficient transfer of large amounts of data. Due to this, HBM is significantly (many times) faster than even the most advanced versions of GDDR, and the clock frequency of such memory modules is low, which gives another advantage — extremely low power consumption and heat dissipation. The main disadvantage of this technology is its high cost.

— HBM2. The second generation of high-speed HBM memory, introduced in 2016. See above for more on the general features of HBM, and HBM2 has doubled throughput compared to the first version of this technology. Thanks to this, such memory is great for resource-intensive tasks like working with virtual reality.

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 speed at which a video card can process data stored in its video memory. In fact, the indicator determines the maximum number of operations to receive or transmit data by a memory module per unit of time. This frequency is expressed in megahertz (MHz) – millions of operations per second. High video memory frequency helps improve performance when performing resource-intensive tasks such as texture processing, graphics rendering and other graphics operations. However, the parameter is by no means the only factor that influences the overall performance of the video card – it is important to take into account the GPU architecture, number of cores, core frequency and other characteristics.

The process technology by which the graphics card's own processor is made.

This parameter is specified by the size of each individual transistor used in the processor. At the same time, the smaller this size, the more perfect the technical process is considered: reducing individual elements allows you to reduce heat dissipation, reduce the overall size of the processor, and at the same time increase its performance. Accordingly, nowadays, manufacturers are trying to move in the direction of reducing the technical process, and the newer the graphics card, the smaller the numbers in this paragraph can be.

The maximum resolution supported by the graphics card — that is, the largest image size (in pixels) that it can display on an external screen.

The higher the resolution, the clearer and better the picture is. On the other hand, with an increase in the number of pixels, the requirements for computing power and, accordingly, the cost of a graphics card increase. In addition, do not forget that you can only appreciate the full benefits of high resolutions on monitors with the appropriate characteristics. On the other hand, in the graphics settings, you can set lower resolutions than the maximum; and a good resolution margin means a good overall performance margin.

As for specific values, the actual minimum for modern video cards is 1600x1200, but higher rates are much more common — up to Ultra HD 4K and Ultra HD 8K.

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.
