Logitech G512 X 75: Specs, Price, Pros & Cons
The G512 X 75 can be half magnetic and half mechanical at the same time. It ships with Kailh mechanical switches, tactile or linear, on all 81 keys. Logitech calls 39 of its sockets Dual Swap beds, and each accepts one of the nine Gateron KS20 analog switches in the box or any standard three- or five-pin mechanical switch, so the board can be set up differently for movement keys and for typing keys.
Tunnel magnetoresistance sensors under those beds read how far an analog switch has traveled. That gives the analog keys what a magnetic board is bought for: an actuation point set anywhere from 0.1 to 4.0 mm, rapid trigger, and Multipoint Action, which fires two commands from one key at different depths. Logitech rates the KS20s at 30 g, against 40 g for the Kailh linear and 50 g for the tactile, so they suit quick taps better than resting fingers.
The 75% layout is the other half of the design. It keeps the function row and a column of navigation keys and drops the number pad, which leaves more of the desk for a mouse that travels a long way at low sensitivity.
Everything else is built for a fixed gaming desk. The board connects by cable only, polls much faster than an ordinary keyboard, and stores three profiles in its own memory so a tournament PC without G HUB still gets your settings. Keycaps are double-shot PBT, N-key rollover is supported, two clickable dials handle volume or macros, and LIGHTSYNC RGB lights the keys and a front lightbar. The case is recycled-content ABS on a silicone gasket mount.
Its buyer plays competitively on a crowded desk and wants analog response under the movement keys and something more familiar under the rest. Anyone who wants magnetic switches with Bluetooth is looking at a compact board such as the Keychron K2 HE. The G512 X 75 leaves out wireless, a numpad and the metal case some rivals at its price use.

How this VS Score was computed
Score 74: each known spec is measured against the median of all keyboards (101 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 58% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
The G512 X 75 is Logitech's compact take on swappable analog switches, and the layout is what makes it interesting. A 75% board gives you the smallest footprint that still keeps a function row, which matters for gaming because the space you save goes straight to mouse movement, which helps if you play at low sensitivity and sweep your arm.
The Dual Swap beds take either the bundled Gateron KS20 analog switches or any standard three or five-pin mechanical switch, and every key arrives with a Kailh mechanical switch fitted. That means you can move the analog switches onto the keys you use for movement and run rapid trigger and adjustable actuation there, while keeping the Kailh switches under everything you type with.
Analog switches are not automatically an upgrade. A very shallow actuation point fires at the lightest touch and rapid trigger resets a key the moment it starts to rise, which is excellent for counter-strafing and awkward for writing an email. Being able to mix the two on one board is the real advantage here.
Two constraints to plan around. It is wired only, so this is a desktop keyboard: there is no Bluetooth or 2.4 GHz option if you also want to use it with a laptop. And at a listed 850 grams with a PCR ABS case, it is lighter than the aluminum boards it competes with on price.
Logitech rates the cable connection at 8,000 Hz polling, which it equates with a 0.125 ms response time, and the board can drop to 1,000 Hz. Onboard profiles mean your configuration follows the keyboard to a machine without G HUB installed.
Buy it if you game seriously, want analog behavior on some keys but not all, and have desk space at a premium. Look elsewhere if you need wireless, a numpad, or spend most of your day typing rather than playing.

The bottom line
The Logitech G512 X 75 earns a VS Score of 74, above the median of the 101 keyboards it is measured against (a score of 50 is level with that median).
- Who it’s for
- A competitive player short on desk space who wants analog response on the movement keys and ordinary switches under the rest.
- Who should look elsewhere
- Numpad users, anyone hoping to use it wirelessly with a laptop, and people who mostly write rather than play should look elsewhere.
- The trade-off that matters
- It works only on a cable. That suits a fixed gaming desk, but the board cannot follow you to a laptop or the sofa.
- The main alternative
- Keychron K2 HE: a compact magnetic board that adds a wireless receiver and Bluetooth, at a lower polling rate.
