Comparison Asus ROG Claymore Core Black Switch vs A4Tech Bloody B314

Traditional keyboards are divided into three main varieties — full-size, compact and ultra-compact. The main difference between them is that full-size models have a Numpad — an additional block with numeric keys and arithmetic signs. Compact models, respectively, do not have a numpad, and in ultra-compact models, the arrow block is either completely absent or located under the Enter key in the form of very small keys.

And full-size, and compact, and ultra-compact keyboards can have different types of layouts. At the same time, the arrangement of letters and numbers above the letters in all types of layouts is the same, the differences are in the shape and position of additional keys (special characters like backslash, system control, modifiers like Shift and Alt, etc.). Here are the most popular options:

— ANSI. The "American" layout format, the distinguishing features of which are, in particular, the same width of both Shift keys, the same labeling and assignment of the Alt keys, the single-row Enter key and the backslash located above it (which is often made slightly longer than the standard key).

— ISO. "European" layout format. The Enter key occupies two rows, while at the top it is slightly longer than at the bottom; the left Shift is shorter than the right one, there is a...backslash next to it; next to the bottom of the Enter may be a second backslash or other special character key; the right Alt is designated as Alt Gr and is intended for entering additional characters in European languages.

— K.S. The "Korean" keyboard layout provides a double-row Enter, as in the ISO described above, however, in this case, the lower part of the Enter is made longer, and not the upper one. The backslash is above Enter, next to Backspace, and Backspace itself is the same length as standard keys (that is, noticeably shorter than in other layouts).

— JIS. Keyboards with a "Japanese" layout have a double-row Enter with an increased length of the upper half — like the ISO described above. However, in this case, the backslash is not located on the left side of the keyboard, but on the right, next to Enter (where an additional symbol key can be located in ISO). Additional character keys may be provided — next to Backspace (as in KS) and/or to the left of the right Shift. In addition, the right Alt can be formatted as Alt Gr.

In addition to compact and full-size, there are also non-traditional keyboard formats:

— Numpad. Separately made block of numeric keys. With the help of such a device, you can, in particular, turn a compact keyboard into a full-size one. Among other things, this combination can be useful for travel: packing a Numpad separately from the keyboard is easier than finding a place for a full-sized "board". Another option for using the Numpad is to connect to a cash register, terminal, etc. to work as a calculator keyboard or in a similar capacity.

— Keypad. A specialized device in the form of a small (approximately 15 – 20 keys) keyboard under one hand; usually, it is complemented by an arm rest, and often also by side buttons for the thumb. Such devices are especially convenient for games and are mainly used in them — certain game actions can be attached to the keypad buttons (including those that are usually implemented through the menu or a key combination on a standard keyboard). The keypad can both complement the main keyboard and serve as a completely separate game pad.

— Non-standard. Non-standard format keyboards that do not belong to any of the varieties described above. The specific design and use of such devices may vary. So, these can be game models in the form of the left half of a standard keyboard (this part is mainly used in games); ultra-compact models for tablets (see "In the direction"); keyboards for TVs, supplemented with special buttons and designed to be held in two hands in the manner of a gamepad, etc.

— Membrane. The name of this type is due to the fact that the contacts under each key are made in the form of two membranes — conductive disks on a flexible film. The return of the keys to their original position after pressing is ensured by the elasticity of the membranes. This design is characterized by low cost and low noise level; in addition, such keyboards are quite resistant to liquid spills (although this is still not recommended). Of the shortcomings, it is worth noting the relatively low durability — 3-4 times lower than that of mechanical ones. In addition, as the keys of this type wear out, the force required to press decreases, they begin to “fall through” under the fingers (“fatigue effect”).

— Mechanical. In this design, springs are used to return the key to its original position after being pressed. Mechanical keyboards are considered more advanced than membrane keyboards: they are more reliable and durable, almost do not lose properties as they wear out, and give a clear tactile feedback. The overall noise level is often higher than that of membrane ones, however, many attribute a characteristic click with each press to the advantages of such models; in addition, completely silent mechanical switches are also available. But of the unequivocal disadvantages, one can name the high cost and sensitivity to spilling liquid (although a mechanical keyboard can also be made waterproof)....r>
— Optical-mechanical. A variation of the mechanical keyboards described above, in which each key is equipped not with a traditional pair of contacts, but with an optical switch in the form of a sensor that receives an infrared beam; when you press the key, this beam is blocked, which serves as a signal for operation. One of the key advantages of such switches is a very high response speed (fractions of a millisecond); this moment is not critical for domestic use, but it can be fundamental for gamers-enthusiasts and e-sportsmen. In addition, the absence of electrical contacts that are prone to wear and oxidize has a positive effect on durability. And although initially the “optics” are more complicated than classic systems with contacts, however, in gaming keyboards, optical-mechanical switches are often even cheaper than pure “mechanics”. And the fact that this option is relatively rare is primarily due to the fact that optical technology appeared not so long ago and is only gaining popularity.

— Membrane + mechanical. A layout in which most of the keys have a membrane design, and some, the most "responsible" ones, are mechanical. About the features of both options, see above, and a similar combination of them is found mainly in gaming keyboards. In this case, the "mechanics" are usually used on the traditional combination of WASD plus on the surrounding keys Q, E, R and F.

— Mechanical-membrane. A hybrid design that combines elements of mechanical and membrane keyboards (see above for more on both). In this case, these features are combined in each individual key. Usually, under each button in such keyboards there is a membrane, however, inside this membrane is not just a pair of contacts, but a mechanical spring system. Thus, this design combines the advantages of both options. At the same time, mechanical-membrane systems are very expensive. Therefore, their main scope is high-end gaming keyboards, and even among such devices this option is quite rare.

— Scissor. A slightly modified version of membrane keyboards (see the relevant paragraph), in which the flexible membrane on each key is supplemented by a two-piece mechanism fastened together in the form of scissors. One of the main features of scissor keyboards is the low key travel (noticeably lower than that of membrane keyboards). Also, this design is less demanding on accuracy, it allows you to achieve a clear pressing regardless of where the finger hit — in the centre or on the edge of the key. The service life of the "scissors" is large; they are more difficult to clean, however, they become dirty much more slowly than "membranes". Among the disadvantages of this option, a slightly increased noise level during operation can be noted — due to the clicking of scissor mechanisms.

The model of switches (switches) used in the keyboard - switching mechanisms installed under each individual key. These details are given if the design uses advanced mechanics, positioned as a better option than traditional switches. Mostly gaming keyboards are equipped with such mechanics.

The most popular switch brands in our time are Cherry MX, considered the "classic of the genre" for high-quality mechanics; Gateron, practically not inferior to him; not so advanced, but also cheaper Kailh and Razer, as well as ultra-budget Outemu. For all these brands, different types of switches have a different stem color, which can be used to determine the features of the keyboard. It is also worth saying that modern mechanical switches are divided into three main varieties: linear, tactile and clicky.

- Linear. Such solutions are closest to conventional membrane keyboards: the key travel is uniform along the entire length, with minimal resistance and the absence of a clear actuation point. There is an opinion that the linear "mechanics" is best suited for games where you have to deal with fast and frequent clicks; however, in practice, this moment largely depends on the personal tastes of the u...ser, nothing prevents the use of such keyboards for working with texts.

- Tactile. Switches with a clearly defined actuation point - a kind of barrier to the path of the key. Such a "barrier" allows you to clearly determine by touch whether the key has worked or not. Tactile keyboards are valued primarily by tech who have to type large volumes of texts.

- Tactile-auditory (Clicky). In such switches, the actuation point is felt not only by touch, but also by ear: the actuation of the key is accompanied by a clearly audible click, which is often compared to the sound of the keys of a typewriter. Due to this, this option is also very popular among users dealing with texts. Some people consider switches of this type not very suitable for games, since they are supposedly not very convenient for frequent, fast pressing; however, a quality Clicky switch is as good as a linear switch in this regard, and the choice depends solely on personal preference. But the unequivocal disadvantages of such keyboards include a rather loud click sound, which in some situations may be superfluous.

As for specific colors, here are their features:

- Red (red). Linear type switches with minimum resistance. They are popular, in particular, among professional gamers who deal with dynamic games and try by all means to speed up their reaction to gaming events. On the other hand, a low force increases the likelihood of accidentally pressing an unnecessary button.

— Black. Another type of linear switches. They have a tighter move compared to Red, which, on the one hand, requires a little more effort, on the other hand, minimizes the chance of accidentally pressing the wrong key.

Blue. Switches in clicky format, with tactile feedback and a click.

— Brown. Switches with tactile feedback, but no "click". The Brown action is great for when you want a keyboard with tactile feedback and at the same time you want to avoid unnecessary noise (although the sound is still louder than on a membrane keyboard). In addition, it is considered a good option for tech who are just starting to get acquainted with mechanical keyboards.

— Silver. Linear switches designed for maximum operating speed. They have a very low stroke - about 1 - 1.2 mm - as well as a very small pressing force, which contributes to high speed. At the same time, the use of such a keyboard requires a certain skill, since even a small effort from an accidental touch usually leads to the operation of a key.

The number of additional keys provided in the design of the keyboard.

Such keys do not belong to the standard layout and are intended for quick access to specific functions or individual applications — for example, to control the media player or open mail with one click. This function is convenient because commands from additional keys are usually recognized by the system regardless of what is on the screen — thanks to this, for example, you do not have to close the text editor to switch tracks in the player.

Note that in this case we are talking about individual keys that have a strictly defined purpose and corresponding markings. Programmable buttons, the Fn key (see below) and the functions of the main keys implemented through Fn are not taken into account in this paragraph.

The number of programmable keys provided in the design of the keyboard. Like the additional ones described above, such keys are located outside the standard layout. At the same time, they do not have a rigidly defined purpose — each individual function can be set by the user himself, hence the name. Some manufacturers, however, can initially programme these keys, but this programme can still be changed if desired.

The advantage of such equipment is obvious: additional features of the keyboard can be easily customized. Gamers especially appreciate this feature, so programmable keys are often found in gaming models. On the other hand, the keys themselves usually have neutral markings (for example, P1, P2 ...), and the user has to remember which function is “linked” to where; this can cause confusion.

Technology aimed at neutralizing phantom button presses in keyboards with gaming ambitions. The function allows you to simultaneously press numerous keys without false positives of adjacent buttons — a similar situation often occurs in membrane keyboards due to their design features.

A wheel for scrolling the image on the screen, similar to that used in modern computer mice. The presence of such a wheel on the keyboard eliminates the need to move your hand to the mouse and back to scroll through the image, which can be especially useful when working with large amounts of text. Also, the scroll wheel is useful if the mouse does not have such a wheel (although such options are becoming less common) or is not available at all (for example, if the keyboard is connected to a laptop).

The colour of the Cyrillic letters printed on the keyboard.

This colour is usually chosen so that the letters are clearly visible. This point does not affect the functionality of the keyboard, and the choice in this case depends mainly on personal preferences. However, there is also a practical point: for inexperienced users who have not mastered touch typing, it is desirable that the letters stand out as much as possible against the background of the keys.

Transparent letters are a separate case — they are used in keyboards equipped with a backlight (see below), due to which such characters, when the backlight is on, are visible even in the dark.

The presence of an additional palm rest in the design of the keyboard. Such a stand is located in the lower (closest to the user) part of the device and is a kind of continuation of the “board”, providing additional support and increasing the comfort of use. However, comfort is largely a matter of personal preference, and not all users like stands; therefore, most often they are made removable.
