Comparison Sapphire Radeon RX 470 11256-35-10G vs Sapphire Radeon RX 470 11256-10-20G

Graphics cards specially designed for cryptocurrency mining(BitCoin, Ethereum, etc.). In this case, it is not just a theoretical possibility to use a graphics card for mining ( many “regular” graphics cards have this possibility), but an optimized design, originally developed taking into account the specifics of the process. Some of these models may be mining-only and may not have video outputs at all.

Mining is the process of "mining" a cryptocurrency by performing special calculations. The technical features of the process are such that in order to achieve maximum efficiency, it is necessary to parallelize the calculations as much as possible. It is thanks to this that graphics cards turned out to be very convenient for mining: the number of individual cores (and, accordingly, parallel computing) in modern GPUs is in the hundreds. Initially, such an application was abnormal, and to transfer the graphics card to the mining mode, one had to resort to various tricks; however, in light of the growing popularity of cryptocurrencies, many manufacturers began to produce video adapters specifically designed for this application.

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 number of DVI-D outputs provided by the graphics card.

The DVI-D interface provides digital video signal transmission. Depending on the version, the maximum resolution of such a video can be 1920x1200 (Single Link) or 2560x1600 (Dual Link); the specific version used generally depends on the general purpose and price point of the graphics card. However, anyway, this interface is very popular in modern monitors, but it is almost never found in other screens.

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. Specifically, up to 4 DVI-D outputs can be provided.

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.

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.

The maximum number of monitors that can be connected to the graphics card at the same time and shared.

Simultaneous connection of several screens allows you to expand the visual space available to the user. For example, it can be useful for designers and layout designers when working with large-format materials, for programmers to separate tasks (one monitor for writing code, the second for searching for the necessary information and other auxiliary purposes), and for gamers-enthusiasts — to ensure the maximum immersion effect. Thanks to advances in technology today , even low — cost graphics cards can typically handle at least three monitors, while advanced models can support four or more displays .

Maximum power consumed by the graphics card during operation. This parameter is important for calculating the total power consumed by the entire system and selecting a power supply that provides the appropriate power.
