What we like
- Dual SWAP lets you put analog TMR switches in 39 dedicated positions and keep conventional mechanical switches elsewhere
- Actuation is adjustable from 0.1 to 4.0 mm, with Rapid Trigger on the analog switches
- 8K polling and 0.125 ms response are available with a toggle back to 1K
- Gasket mount, double-shot PBT keycaps and recycled-plastic construction feel premium at $159.99
- Nine Gateron K20 analog switches are included, so you can start tuning right away
Could be better
- Wired only, which is a letdown next to wireless 75% boards
- Only 39 positions support analog switches, so it isn't a full hall-effect-style board
- Analog tuning and profiles depend on G HUB software
- Extra analog switches cost more, so a fully analog setup raises the real price

Build and Design
The G512 X 75 uses a silicone gasket mount, and Logitech says the case uses up to 44% certified recycled plastic. The double-shot PBT keycaps should hold up well. Reviewers have also praised the lightbar and the overall finish. The board weighs about 850 g without the cable, so it stays put on a desk.
It comes in linear (white) and tactile (black). Logitech also sells a 98-key version at $199.99 if you want a numpad.
The Dual SWAP Idea
Most analog keyboards make you buy into magnetic switches across the whole board. Logitech takes a different route here. Thirty-nine positions are TMR beds that accept analog switches, and the rest take regular mechanical switches. The box includes nine Gateron K20 analog switches.
This works well if you mainly want analog behavior on WASD and a few nearby keys. Typing keys can stay mechanical, and you can add more analog switches later.
Performance and Features
Actuation is adjustable from 0.1 to 4.0 mm. Rapid Trigger re-actuates the instant you release a key, which suits shooters and rhythm games. The 8K polling rate and 0.125 ms response are there if your setup can use them. You can toggle back to 1K.
The SAPP rings add a second actuation point at 2.8 mm. Logitech suggests this for combos in compact layouts. G HUB handles remapping, macros and analog profiles.
How It Compares
The Wooting 80HE is the benchmark for a full-analog 75% board. If you want analog on every key, look at that board or the Keychron Q1 HE instead. The G512 X is the better fit if you want a cheaper entry and the freedom to mix switch types. The Logitech G Pro X TKL Rapid is the older Logitech option. This one adds TMR sensing and a more compact layout.
The main drawback is that it’s wired only. Wireless 75% boards cover more uses.
Who Should Buy This
Buy it if you play competitive FPS or rhythm games, want Rapid Trigger and adjustable actuation, and like tinkering with switches. It’s also a good first analog board if you don’t want to commit your whole keyboard to magnetic switches.
Skip it if you need wireless, want analog under every key, or prefer to avoid companion software. Anyone who wants a numpad should look at the 98-key version.
