Comparison SteelSeries Apex Pro Mini vs SteelSeries Apex Pro TKL

The length of the cable that the keyboard is equipped with for wired connection (see "Connection type").

When choosing this parameter, you should first of all take into account the distance from the device to the connection port: a cable that is too short may simply not reach the connector, and a cable that is too long may get confused at hand and create inconvenience. As for specific values, the reference length is 1.8 m. However, there are cables both shorter and longer.

— 100% (full-sized). Classic layout with 104/105 keys featuring a full NumPad, dedicated F1–F12 row, and navigation cluster including Insert/Delete, Home/End, PgUp/PgDn; this version is valued for its familiar geometry, typing speed, and ease of frequent number entry, making it optimal for work in Excel, accounting, IDEs, and editing programs, while in games, the NumPad is often used for binds and macros; compared to TKL/80% without a numeric block, as well as 96% and 1800-compact, the 100% format offers maximum comfort and requires less retraining, but takes up more desk space and pushes the mouse further away, so for compact workplaces, it might be wiser to consider smaller formats.

— 1800 (compact full-sized). A full-featured layout with a numeric block but in a narrower body: the NumPad is shifted closer to the main field, and navigation is often placed above it or compacted next to the arrow keys. It feels like "100%", but is shorter by a few centimeters, so the mouse is closer to the center, offering more comfort for wrists. Compared to TKL, you retain fast number entry, and against 96%, you gain a slightly more "airy" geometry with clear orientation. Note the non-standard sizes of some keys and the right block, which sometimes require special keycap sets. This format is convenient for Excel, accounting, IDEs, and editing, while offering gamers the NumPad for macros while saving desk space.
...r> — 96% (compact full-sized). Keyboards that preserve all key zones of 100% (F1–F12 row, arrow keys, navigation, and NumPad) but place them in a tight "grid" layout, almost like TKL in width. The numeric block is shifted closer to the main area, while Insert/Home/End and PgUp/PgDn are often reduced to 1u and grouped above the arrows or next to the NumPad. Compared to the 1800 format, 96% is even more compact and visually "smoother," and against TKL, you do not lose the speed of number entry. Note the possible non-standard sizes of the right shift, zeros, and plus on the NumPad, requiring a more selective keycap choice. This format is chosen for Excel and accounting, editing and coding, while gamers use the NumPad for macros, gaining maximum functions with minimal table width.

— 80% (TKL, without Num-block). A full-featured keyboard without a numeric block: retains the F1–F12 row, arrow keys, and navigation Insert/Delete, Home/End, PgUp/PgDn, but is considerably narrower, bringing the mouse closer to the center, which is easier on the shoulders and wrists. Gamers and developers favor this format: there’s more desk space, while familiar keys and hotkeys remain in place. Compared to 100%, you only lose quick number entry, which can be supplemented with a separate wireless NumPad. In comparison to 75%, TKL is more readable and "airy" thanks to its separate navigation block; unlike 96%, it is more compact for mouse grip, though lacking a NumPad. The 80% (TKL) format is optimal for FPS, work in IDEs, editing, and everyday office tasks where numbers aren’t entered continuously.

— 75% (compact TKL, without Num-block). "Almost TKL," where all main keys are within reach, but the body is shorter by several centimeters due to a tight "staircase" arrangement of arrows and navigation. Compared to 80%, it decreases the distance between hands and mouse, enhancing ergonomics for prolonged use, and relative to 100% and 96%, you lose only the numeric block, gaining space for the mouse and a more neutral shoulder posture. This format is chosen for IDEs and design packages, FPS and MOBA, mobile setups with narrow desks, when numbers are entered infrequently or supplemented with an external NumPad. Note: 75% may have non-standard sizes in the right block and individual keys, which is important when selecting keycaps and stabilizers.

— 65% (ultra-compact, without F-row). "Condensed TKL": the alphanumeric block, arrow keys, and a pair of navigation keys remain in place, while the NumPad and the top F1–F12 row are accessed via Fn. This layout is significantly narrower in width, moving the mouse closer to the center, which reduces the spread of arms — ideal for narrow desks, when working on a laptop, and for travel. Compared to 60%, the 65% format is more practical thanks to dedicated arrows and Delete; against 75% and 80%, it is more compact but often requires getting accustomed to layers. Possible non-standard sizes of the right shift and navigation keys are important when choosing keycaps. In real-world scenarios, the 65% format is excellent for IDEs, streaming, and FPS/MOBA games, while regular number entry is complemented by an external wireless NumPad.

— 60% (mini). Classic "trimmed" layout with ~61/62 keys without NumPad, no F1–F12 top row, and no separate navigation cluster: all accessed through the Fn layer, with arrows usually assigned to combinations. Compared to 65%, this format is even more compact but often requires acclimatization to layers; against 75%/80%, you save desk width and achieve a more neutral shoulder posture, at the cost of losing "quick" F-keys. The strong points of 60% are portability, free space for the mouse and mat, and reduced arm movement between keyboard and mouse, making it popular with FPS gamers, streamers, and those working on laptops at narrow desks or traveling. If active number entry or "hot" F-keys are needed, an external wireless NumPad and well-thought-out layer layout help.

— 40% (ultra-mini). Radically compact layout with about 40–50 keys, lacking a number row, arrows, and F-keys: all are accessed via Fn layers, combined presses, and macros, often with an ortholinear matrix. Due to the minimal width, the mouse is closer to the center, reducing hand spread and freeing up desk space, appreciated by mobile users and minimalists. Compared to 60% and 65%, the 40% format requires more serious adaptation and thoughtful firmware (QMK/VIA, home-row mods, tap-dance), and keycap selection is more challenging due to non-standard sizes. The strong point is portability and speed after getting used to it; weakness — reliance on layers and inconvenience of frequent number entry and arrow navigation. The 40% format is practical for travel, work on laptops with docking stations, text editing with hotkeys, and streaming, while numbers are usually supplemented with an external NumPad.

Keyboard switch durability is measured by the number of presses the keys can withstand before they begin to show signs of wear or malfunction. Switches can have a lifespan of several million to tens of millions of clicks. In laboratory conditions, this parameter is checked using special testing machines, which diligently press the keys the required number of times, on the basis of which a verdict is made regarding the approximate service life of the switches.

The frequency with which the computer polls the keyboard to determine which keys are currently being pressed. The parameter is measured in Hertz (Hz) - they show how many requests are executed per second. Higher Hertz means keystrokes are detected and registered faster. This can provide an advantage in games and tasks that require the highest possible input speed.

As for specific values, for most ordinary users the standard polling rate of 125 Hz will be quite sufficient. Gaming keyboards can have a frequency from 1000 Hz (keystrokes in this version are recorded every 1 ms), and advanced models for true e-sportsmen - up to 8000 Hz (the reaction time is 0.125 ms).

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.

Built-in connectors in the case allow you to connect a flash drive, a mouse, a 2.4 GHz receiver, or a cable for charging gadgets to the PC without running a wire to the main unit. Such a USB hub saves laptop ports, simplifies cable management, and is often called USB pass-through, although technically it's the same mini-hub with 1-2 ports. In most models, the speed corresponds to USB 2.0, and power is limited: connecting external SSDs and "power-hungry" accessories is not always correct; for stability, some keyboards require a second plug or USB-C with increased current. Compared to keyboards without a hub, convenience is higher, compared to a separate desktop hub, it's more compact but has more modest functionality. A practical example: a gaming laptop with two ports works with a mouse and flash drive through the keyboard's USB hub, while the keyboard itself remains connected to the PC with a single cable.

Features of the cable with which the device is equipped. First of all, it's worth noting the connection interface used in a wired keyboard. Namely:

— USB-A. A standard universal port for connecting peripherals, present in almost all modern computers—from desktop PCs to microcomputers. USB keyboards are the most universal, so this option is the most common today. The main disadvantage of this option is that the USB port occupied by the keyboard might be needed for another peripheral device; however, this problem is easily solved—for example, by using a USB hub or purchasing a keyboard with its own hub (see below).

— USB-C. The USB-C plug is reversible, compact, and universal, so the keyboard easily connects to modern laptops, PCs, and docking stations. There is no difference in delay and functionality compared to USB-A: in both cases, the keyboard is recognized as a common USB-HID, NKRO, and high polling rate do not depend on the type of plug. Mechanically, USB-C is usually more durable for wear (up to ~10,000 insertion cycles compared to ~1,500 for USB-A), and it is also easier to insert "by feel". Compatibility is resolved with a cable or mini-adapter A↔C, which may be included. Bottom line: if you have a free USB-C port—opt for a keyboard/cable with USB-C; if there are few "C" ports or the PC is stationary—USB-A is just as good in operation.

— PS/2. A specialized round-shaped port used for connecting keyboards and mice; modern PCs may have either two ports, one for each, or a single universal port. In any case, this connection method is convenient because all USB ports remain free; this can be important when using a large number of USB peripherals. At the same time, the PS/2 port itself is quite large and not suitable for laptops and other compact equipment, and therefore is found only in desktop PCs. Even in these cases, it is advisable to confirm the availability of PS/2 before purchasing a keyboard with such a plug.

— USB or PS/2. Generally, this means USB keyboards equipped with an adapter for PS/2 ports. The features of both interfaces are described above; here we note that this option is the most versatile, allowing for a choice of connection method depending on the situation. Furthermore, it is convenient because there are relatively few PS/2 models, and it's easier to find a suitable USB keyboard equipped with an adapter. The adapters themselves are inexpensive and do not significantly affect the device's price; naturally, they are also sold separately, although a set is often a more preferable option.

— Brand-specific. Connection using a unique plug that is not among the standard (described above) interfaces and is mainly used in technology from a specific brand, at best in some devices from third-party manufacturers. This option is quite convenient for tablet accessories (see "By Direction").

In addition to connection, the keyboard cable may have additional properties:

— Detachable.... A cable that can be disconnected from the keyboard. Almost all devices with two connection options—wired and wireless—have this feature: in wireless mode, the cable can be removed so that it doesn't get in the way. Although, there are also purely wired devices with such a cable—mainly laptop ones, where the cable is removed for convenience during transport. It is also worth noting that a universal port is most often used to connect the cable, so if necessary, the cable can be replaced with another—e.g., a longer one.

— Braided. The presence of an additional braid on the cable makes it more durable, reliable, and resistant to bends. On the other hand, the braid tends to accumulate dirt and fray with wear; because of this, the cable's casing quickly loses its marketable appearance compared to keyboards without braiding. And such a cord costs more than a regular smooth one.

A connector in the keyboard case for attaching a removable cable, found in both wired models and wireless ones with a battery, where through this port the keyboard is charged and, if necessary, operates "wired" without delay.

— microUSB. One of the miniature versions of the USB connector, still popular in gadgets despite the emergence of the more advanced USB-C. It has comparatively modest capabilities (in particular, it is inferior to USB-C in terms of maximum possible charging power), but this rarely proves critical. Meanwhile, there is an abundance of microUSB cables and chargers.

— USB-C. The latest (as of the end of 2025) type of USB connector. It is symmetrical, allowing the cable to be inserted either way, eliminating the possibility of incorrect connection. USB-C is more reliable, has an extended lifespan, and supports higher data transfer and charging speeds. Additionally, it is compatible with modern devices and is gradually becoming a universal standard, making keyboards with this connector more convenient and relevant for users.

Keyboards made in a Skeleton case.

The main difference between such cases and the classical ones is that the mechanism of each key is not hidden at the base of the keyboard, but, on the contrary, rises somewhat above it. Due to this, the keys can be easily removed and put back into place, which makes it much easier to clean from dust and dirt. And in gaming keyboards of this type, the kit often includes interchangeable buttons that differ in colour and texture from the main ones. Actually, almost all models with this feature are specifically gaming (see "By Direction").
