Comparison It-Blok Game i7 7700 D vs It-Blok Optimal i7 7700 C

The general type of computer. In addition to classic desktop models (including gaming purposes), more unusual solutions are also found nowadays: monoblocks, nettops, microcomputers. Here are the features of each type:

— Desktop. Traditional desktop PCs, in other words, models that do not fit into any of the more specific categories. For the most part, they are not even desktop, but rather "below the table" — they are carried out in vertical cases, most often placed under the tabletop, horizontal system units are extremely rare among such devices.

— Game. A variety of desktop computers, designed for professional players and gamers-enthusiasts. Such models are necessarily equipped with a powerful hardware, which allows you to comfortably play even demanding modern games. In addition, they often provide various additional features that are useful for specialization: built-in overclocking tools, high-end customizable cooling systems, etc. Another feature of gaming PCs is a distinctive design, often quite original: in an “aggressive” style, with backlight, unusual body shape, transparent inserts, etc.

— Monoblock. Monoblocks are devices that combine a screen, system unit electronics, a set of connectors and acoustics in one case; in other words, these are monitors with built-in comp...uter “hardware”. This design has two main advantages. Firstly, the system initially has a display, and it is quite large and optimally suited to its configuration — so the user does not need to look for a separate screen. Secondly, such a computer takes up very little space — only slightly more than a monitor with the same screen size; and the absence of a separate system unit can be written down as an advantage. On the other hand, if in a regular PC the “system unit” and the monitor can be selected separately, at your discretion, then in monoblocks this is not possible — you have to get by with the combinations that the manufacturer initially offers. In addition, the possibilities for modification and upgrade for such models are noticeably more modest than for traditional ones, and there is no talk of replacing the screen at all.

— Nettop. Devices also known as "mini PCs". They are small and modestly equipped — in particular, a very limited set of ports. In addition, many nettops do not differ in performance and are designed mainly for working with documents, surfing the Internet and other simple tasks. However, there are also quite powerful performant solutions. Anyway, the main advantage of the nettop is compactness.

— Microcomputer. As the name suggests, this type of computer is extremely tiny—comparable in size to a flash drive—and looks more like portable adapters for external screens than stand-alone devices. The case of such an “adapter” usually has its own HDMI connector, which is used to connect to a monitor or TV; the same port provides power. And the case most often provides for a “mobile” energy-saving processor with integrated graphics, a compact SSD or eMMC drive, and wireless modules. Peripherals like keyboards and mice are connected mainly via Bluetooth, but many models have wired connectors like USB, and sometimes in quite a decent amount (2 or even 3). In general, such a device can be a good alternative to a tablet or laptop for those who often move between different workplaces — the main thing is that these places have appropriate screens for connection. The power of microcomputers, naturally, is low, but they are not designed for "heavy" tasks.

— Thin client. Thin clients are computers designed to be used in terminal mode for external servers. In this case, all resource-intensive calculations are performed by the server, and the functions of the thin client are limited to entering initial data and receiving results. Most of these computers do not involve independent work at all, but this is not a drawback, but a feature of specialization. In general, this format of work is not used in everyday life and in the ordinary business sphere, but it is perfect for some highly professional tasks. And since the thin client does not need high performance, it can be made as compact, lightweight and inexpensive as possible.

The model of the chipset used in the standard configuration of the PC.

A chipset can be described as a set of chips that provides the combined operation of the central processor, RAM, I / O devices, etc. It is this chipset that underlies any motherboard. Knowing the chipset model, you can find and evaluate its detailed characteristics; most users do not need such information, but for specialists it can be very useful.

The amount of random access memory (RAM, or RAM) that came with your computer.

The overall performance of the PC directly depends on this parameter: ceteris paribus, more RAM speeds up work, allows you to cope with more resource-intensive tasks, and facilitates the simultaneous execution of numerous processes. As for specific numbers, the minimum volume required for the stable operation of a general-purpose PC nowadays is 4 GB. Smaller amounts are enough for microcomputers and thin clients, and at least 8 GB is installed in gaming systems, on the contrary. 16 GB and even more so 32 GB are already very solid volumes, and in the most powerful and performant systems there are values \u200b\u200bof 64 GB and even more. Also on the market you can find configurations without RAM at all — for such a device, the user can choose the amount of memory at his discretion; for a number of reasons, this configuration is especially popular in nettops.

Note that many modern PCs allow for an increase in the amount of RAM, so it does not always make sense to purchase an expensive device with a large amount of "RAM" — sometimes it is more reasonable to start with a simpler model and expand it if necessary. The possibility of upgrading in such cases should be clarified separately.

The clock speed of the RAM that comes with the PC. This is one of the parameters that determine the capabilities of RAM: with the same amount and type of memory (see above), a higher clock frequency will mean faster performance. However such details are rarely required by an ordinary user, but they are important for enthusiasts and professionals.

Also note that this indicator can be used to determine the possibilities for upgrading the system: the motherboard will be able to work normally with brackets that have the same or lower clock frequency, but compatibility with faster memory should be specified separately.

The number of slots for RAM modules provided on the PC motherboard. In this case, we are talking about slots for removable strips; for a PC with built-in memory, this parameter is irrelevant.

The slots available on the "motherboard" can be occupied all, partially or not occupied at all (in models without RAM). Anyway, you should pay attention to their number if the initially installed amount of RAM does not suit you (or ceases to suit you over time), and you plan to upgrade the system. The smallest amount found in a PC with removable memory is 1 slot ; if it is busy, you will only have to change the bar when upgrading. More connectors for RAM are always paired, this is due to a number of technical nuances; most often this number is 2 or 4, but it can be large — up to 16 in powerful workstations.

Note that when planning an upgrade, you need to take into account not only the number of slots and type of memory (see above), but also the characteristics of the motherboard. All modern "motherboards" have restrictions on the maximum amount of RAM; as a result, for example, the presence of two DDR4 slots does not mean that two strips of maximum capacity can be installed in the system at once, 128 GB each.

The maximum amount of RAM that can be installed on a computer. It depends, in particular, on the type of memory modules used, as well as on the number of slots for them. Paying attention to this parameter makes sense, first of all, if the PC is bought with the expectation of upgrading RAM and the amount of actually installed memory in it is noticeably less than the maximum available

So the amount of maximum installed memory depends on the number of slots in the PC and can be from 16 GB(a modest PC) to 64 GB and above. The most popular on the market are PCs with a maximum installed 32 GB of memory.

The amount of native memory provided by the discrete graphics card (see "Graphics card type").

The larger this volume, the more powerful and advanced the video adapter is, the better it handles with complex tasks and, accordingly, the more expensive it is. Nowadays, 2 GB and 3 GB are considered quite modest, 4 GB are not bad, 6 GB and 8 GB are very solid, and more than 8 GB means that we have a specialized PC built for maximum graphics performance.

The number of internal 3.5" component bays in the computer. This form factor is standard for hard drives, and is also often used in other types of drives; accordingly, the more bays, the more drives you can install on your computer.

Paying attention to the number of internal 3.5" bays makes sense, first of all, if you purchase a configuration without drives or plan to upgrade your PC in the future. It is worth noting that it is recommended to install drives not in a row, but through one slot — for cooling efficiency ; so ideally the number of slots should be twice the number of devices to be installed.

In most desktop PCs, this assortment is determined both by connectors on the "motherboard" and on a discrete graphics card, among which VGA, DVI, HDMI output(there are models where HDMI 2 pcs), HDMI input, DisplayPort, miniDisplayPort. More details about them.

— VGA. He's D-Sub. Analogue video output with maximum resolution up to 1280x1024 and no audio support. It is rarely installed in modern devices, but it can be useful for connecting certain models of projectors and TVs, as well as outdated video equipment.

— DVI. Modern PCs can be equipped with both pure digital DVI-D and hybrid DVI-I; the latter also allows analogue connection, including work with VGA-devices through an adapter, and in analogue format has a resolution of 1280x1024. In digital DVI, this parameter can reach 1920x1200 in single-link mode (single link) and 2560x1600 in dual-link mode. The presence of a dual-channel mode must be specified separately.

— HDMI output. Digital output originally designed for HD content — high-definition video and multi-channel audio. The HDMI interface is almost mandatory for modern HD multimedia technology, and it is also extremely popular in computer monitors — so the presence of such an output on a PC provides ve...ry extensive features for connecting external screens and even high-end audio devices. Some devices may even have 2 HDMI outputs.

— HDMI input. Your PC has at least one HDMI input. See above for details on the interface itself; here we note that it is the inputs of this format that are found mainly in monoblocks (see "Type"). At a minimum, this allows you to use the monoblock's own display as a screen for another device (for example, as an external monitor for a laptop). However, there are other, more specific options for using the HDMI input — for example, recording an incoming video signal, or transferring (switching) it to one of the PC video outputs.
Both the HDMI inputs and outputs in modern PCs may correspond to different versions:

• v 1.4. The earliest standard widely used today. Supports resolutions up to 4096x2160 and frame rates up to 120 fps (however, only at a resolution of 1920x1080 or lower), and can also be used to transmit 3D video. In addition to the original version 1.4, you can find improved v 1.4a and v 1.4b — in both cases, the improvements affected mainly the work with 3D.
• v2.0. The standard, also known as HDMI UHD, was the first to introduce full support for UltraHD 4K, with frame rates up to 60 fps, as well as compatibility with a 21:9 aspect ratio. In addition, the number of simultaneously transmitted channels and audio streams has increased to 32 and 4, respectively. It is also worth noting that initially version 2.0 did not provide support for HDR, but it appeared in update v 2.0a; if this feature is important to you, it's ok to clarify which version 2.0 is provided in the PC, the original or the updated one.
• v2.0b. The second update of the above v 2.0. The main update was the expansion of HDR capabilities, in particular, support for two new formats.
• v2.1. It is also HDMI Ultra High Speed: the bandwidth has been increased to such an extent that it became possible to transfer 10K video at 120 fps (not to mention more modest resolutions) as well as work with extended colour schemes up to 16 bits. The latter may come in handy for some professional tasks. However, note that all the features of HDMI v 2.1 are available only when using cables designed for this standard.

— Display port. A digital media interface similar in many respects to HDMI, but mainly used in computer technology — in particular, it is widely used in Apple computers and monitors. One of the interesting features of this standard is the ability to work in the daisy chain format — connecting several screens to one port in series, transmitting its own signal to each of them (although this function is not technically available with all screens for this interface). DisplayPort is also on the market in several versions, the current ones are as follows:

• 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 is support for AMD FreeSync, a technology for synchronizing the monitor's frame rate with the signal from an AMD graphics card.
• 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 mentioning 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. The newest version widely used in modern PCs. Formally, the maximum connection speed 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.

— miniDisplayPort. A smaller version of the DisplayPort connector described above, may also correspond to different versions (see above). Note that the same hardware connector is used in the Thunderbolt interface versions 1 and 2, and the graphic part of this interface is based on DisplayPort. Therefore, even some Thunderbolt monitors can be directly connected to miniDisplayPort (although it is desirable to clarify this possibility separately).

— COM port (RS-232). Serial port, originally used to connect dial-up modems and some peripherals, in particular, mice. However, today this interface is used as a service interface in various devices — TVs, projectors, network equipment (routers and switches), etc. Connecting to a PC via RS-232 allows you to control the operation parameters of an external device from a computer.
