Comparison Gigabyte GeForce GTX 1080 Turbo OC 8G vs INNO3D GeForce GTX 1070 ICHILL X4

A GPU is a type of graphics processor that determines the fundamental performance characteristics of a video adapter. Today there are two main manufacturers - AMD and NVIDIA. Intel has also entered the leadership race with its Intel Arc line of discrete graphics.

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 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 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 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 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 DVI-I outputs provided by the graphics card.

DVI-I is a hybrid standard that allows both digital and analogue video to be transmitted. The "digital part" of such an interface is similar to DVI-D, it can be performed in the Single Link or Dual Link version and support resolutions up to 1920x1200 or 2560x1600, respectively. The “analogue part” corresponds to VGA in terms of capabilities: it supports resolutions up to 1280x1024, and the VGA screen can be connected to the DVI-I output via a simple adapter.

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. Modern graphics cards can have up to 3 DVI-I connectors.

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 version of the DisplayPort and/or miniDisplayPort interface used by the graphics card. For the interfaces themselves, see the relevant help items; here we recall that they differ only in the type of plug. So the list of versions for both cases is the same, it looks like this:

— v 1.2. The earliest widely used version (2010). However, already in this version, 3D compatibility and the daisy chain mode appeared. The maximum fully supported resolution when connecting a single monitor is 5K (30 fps), transmission up to 8K is possible with certain restrictions; a frame rate of 60 Hz is supported up to a resolution of 3840x2160, and 120 Hz — up to 2560x1600. And when using daisy chain, you can connect up to 2 2560x1600 screens at 60 frames per second or up to 4 1920x1200 screens at the same time. In addition to the original version 1.2, there is an improved v 1.2a, the main innovation of which was support for AMD FreeSync, a technology used in AMD video cards to synchronize the refresh rate of the monitor with the actual frame rate output by the video adapter.

— v 1.3. An update introduced in 2014. The increased bandwidth made it possible to provide full, without restrictions, support for 8K at 30 fps, as well as transmit 4K images at 120 fps, sufficient for 3D work. Resolutions in daisy chain mode have also increased — up to 4K (3840x2160) at 60 fps for two screens and 2560x1600 at the same frame rate for four. Of the specific innovations, it is worth me...ntioning the Dual Mode mode, which allows you to connect HDMI and DVI devices to such a connector through the simplest passive adapters.

— v 1.4.Version introduced in March 2016. Formally, the bandwidth has not increased compared to the previous version, but thanks to signal optimization, it became possible to work with 4K and 5K resolutions at 240 fps and with 8K at 120 fps. However for this, the connected screen must support DSC encoding technology — otherwise, the available resolutions will not differ from version 1.3. In addition, v 1.4 added support for a number of special features, including HDR10, and the maximum number of simultaneously transmitted audio channels increased to 32.

—v 1.4a. An update released in 2018 "quietly" — without even an official press release. The main innovation was the update of Display Stream Compression technology from version 1.2 to version 1.2a.
