Logitech G512 X Review: Is the Dual Swap Feature Worth It?

After the massive success of the Logitech G Pro X2 Superstrike, expectations for Logitech's next big release were sky-high. While our Logitech G512 X review might suggest this isn't a total industry revolution, it introduces high-level innovations that make it an essential piece of kit for competitive players.

The Dual Swap Revolution

The standout feature of the Logitech G512 X is undoubtedly its "Dual Swap" functionality. Utilizing tunnelling magnetoresistance (TMR) sensors located beneath the keycaps, 39 switch beds can be toggled between analogue and mechanical modes. This allows users to customize their experience with extreme precision:

Analogue switches: Best for rapid trigger and custom actuation.
Mechanical switches: Ideal for a classic typing feel and tactile feedback.

In practice, the most effective setup involves placing analogue switches on your WASD keys and the space bar, while leaving the rest of the board mechanical. The process is seamless; the caps and switches are hot swappable, meaning you never have to unplug the keyboard to make changes. A dedicated "scan" button on the top left identifies which switches are in use and highlights them with RGB lighting for easy recognition.

Advanced Actuation with SAPP Rings

While competitors like Wooting offer all-analogue boards, the G512 X takes a unique approach using SAPP (second actuation pressure point) rings. These small rubber rings sit under the keycaps to provide resistance at the 2mm mark. This enables multipoint actuation, allowing you to map different actions to a single key—such as setting the "W" key to walk at a shallow 0.1mm depth and sprint once you hit the 2mm threshold.

Smart Design and Aesthetic Integration

Logitech has leaned into its Swiss roots with a design that is incredibly efficient and organized. The keyboard features integrated storage compartments:

A small bay for nine spare switches.
Dedicated space for five SAPP rings.
The keyboard feet actually double as switch and keycap pullers.

Visually, the board is striking. It features a dedicated light bar at the bottom and individually lit keys. One of the top-right dials is pre-set to control RGB, allowing you to dim the lights instantly. This integrates perfectly into the broader G5 ecosystem, which includes the G522 gaming headset and the G502 X Plus mouse.

Gaming Performance and Build Quality

When it comes to pure gameplay, the Logitech G512 X is a beast. The combination of TMR sensors and rapid trigger technology provides a level of responsiveness that traditional keyboards simply cannot match. During testing in Counter-Strike 2, the ability to stop movement instantly upon releasing a key provided a significant advantage for aiming precision.

The build quality remains premium throughout. The double-shot PBT keycaps feel smooth, and even the optional $45 acrylic palm rest serves a functional purpose by diffusing the light bar's glow. While it is an extra expense, the palm rest enhances the aesthetic and is easy to clean.
