The Logitech G512 X is a top-of-the-line gaming keyboard with genuinely innovative features and a striking design. Logitech has managed to create a feature-packed, cutting-edge keyboard that looks and feels like an enthusiast-grade option, a significant achievement.
Design and Features
The G512 X is a wired keyboard available in 98 or 75 key layouts, with tactile or linear switches, and colour options of black or white. The tested G512 X 75 in white features turquoise accents and keys, with additional white/black keycaps included. A standout design element is the RGB Lightbar spanning the front, customisable to match the keys. The plastic body feels premium and durable.
A separate acrylic wrist rest with a matte UV coating and laser-etched patterns is available for £34.99/£39.99. It offers visual appeal but average comfort.
Cutting-Edge TMR Switches
The G512 X uses TMR switches utilising quantum tunnelling for lower power consumption, faster response, better temperature stability, and reliability. It features 39 hybrid TMR switch beds near WASD and arrow keys, supporting 3-pin or 5-pin analogue or mechanical switches—Logitech's Dual Swap system. The keyboard comes with mechanical Romer-G switches and nine premium Gateron KS-20 magnetic analogue switches stored in dedicated slots at the top.
Keyboard feet double as switch and keycap pullers. Two dials in the top right corner offer 24 ratchets, bidirectional and clickable for extensive customisation.
Analogue Features
With analogue switches, the keyboard supports per-key actuation adjustment (0.1mm–4.0mm), rapid trigger, multipoint action, and key priority (snap tap). Five SAPP rings are included for tactile feedback at the second actuation point, enabling dual actions like walk and sprint on one key.
Logitech claims true 8k polling with a 0.125ms processing rate, faster than human capability.
Performance
The G512 X delivers an excellent typing experience with pre-installed Romer-G tactile switches, double-shot PBT keycaps, and a silicon gasket mount. For gaming, installing analogue keys and adjusting actuation improved responsiveness in titles like Marathon and Warzone. The switch removal and storage integration make customisation accessible for beginners.
Logitech G Hub software allows easy customisation of macros, RGB, polling rate, and actuation.
Value for Money
Priced at £199.99 (98) and £169.99 (75), it competes with the Wooting 80HE (£176 plastic, £264 zinc), Razer Huntsman V3 Pro TKL (£219.99), and SteelSeries Apex Pro TKL Gen 3 (£209.99). Unlike competitors, the G512 X offers both analogue and mechanical switches, TMR technology, and a large RGB lightbar.
Overall Thoughts
The Logitech G512 X combines exceptional typing feel, performance, customisation, and cutting-edge TMR switches in a compact, stylish design. It is the best overall keyboard tested for typing and gaming, earning a 5/5 score.
