Logitech G512X Review: A Creative TMR Keyboard With Real Potential

Introduction

Logitech has not always been known for pushing creative boundaries with its gaming keyboards. The G512X changes that reputation in a meaningful way. This 75% board brings TMR sensing, hot-swappable magnetic switches, and a genuinely clever design to a segment that often feels repetitive. It is not a perfect keyboard, and some of its most ambitious features fall short in practice, but it represents a clear step in the right direction for the brand.

The G512X is available in two switch options: tactile and linear. There are also two colorways: black and white. The version reviewed here is the 75% layout, which keeps the function row, arrow keys, and adds two knobs in the top corner. A full-size version with a number pad is also available.

Design and Build Quality

At first glance, the G512X looks a little like a toy. The entire case is made of unapologetic plastic, not aluminum or any fancy polycarbonate blend. It feels a bit cheap in the hand, sitting in an odd middle ground between budget and premium. That said, the design language is more creative than most gaming keyboards. The aesthetic leans slightly cyberpunk, and with the RGB turned off, the board looks sleek and understated.

The keycaps are aggressively gamey, with large legends and a very pronounced texture. That texture could be a genuine plus if you want extra grip while typing or gaming. For most users, though, the keycaps look and feel inexpensive. They are not the best shine-through keycaps available, even though the RGB glow through them is surprisingly bright.

One of the most impressive design touches is on the back of the keyboard. The included keycap and switch puller doubles as adjustable feet. You simply attach them to the bottom of the board to change the typing angle. It is clever engineering that few other manufacturers have attempted. The only downside is that these feet are plastic, so breaking them while pulling switches or keycaps would leave you without adjustable feet.

There is also a clear plastic bar along the front edge of the keyboard. This bar aligns perfectly with an optional wrist rest, and the RGB lighting shines through the entire wrist rest when attached. It is a thoughtful detail that adds visual cohesion to the setup.

Keycaps and Typing Feel

The typing experience on the G512X is a mixed bag. The tactile switches installed in this version have a substantial bump and a slightly scratchy feel, which some users will appreciate. The sound profile, however, is dragged down by the keycaps. The overall acoustics are not great, and the keyboard sounds noticeably worse than it should given the switch quality.

If you are looking for a creamy, thocky typing experience out of the box, this is not the keyboard for that. The keycaps and case materials work against the switches. To get a truly satisfying sound and feel, you would likely need to replace both the switches and the keycaps, which adds cost and effort.

That said, the tactile switches themselves are enjoyable. They offer a clear, substantial bump that makes typing feel deliberate. The scratchiness is a personal preference thing, and some typists genuinely like that texture. It is not a bad typing experience, just one that requires some investment to elevate.

Hot-Swappable TMR Switches

The headline feature of the G512X is its TMR technology. TMR stands for tunnel magneto resistance, a sensing method that detects magnets and their position in space. It is similar to Hall effect sensing but uses less power and takes up less space on the PCB. This allows the keyboard to include hot-swappable sockets, which is a significant advantage.

The keyboard ships with either tactile or linear switches installed. You can pull these out and replace them with magnetic switches, which are stored in two small slots on the back of the keyboard. These included magnetic switches are from Gateron and are generally considered mid-tier. They work, but they are not exceptional.

To activate the magnetic switches, you press a small scan button on the back of the keyboard. The board then detects which keys have magnetic switches installed and makes them appear in the software. From there, you can enable rapid trigger, set custom actuation points, and use SOCD features like Snap Tap. These features are genuinely useful for competitive gaming, especially for players who spam keys or need precise movement control.

There is a significant catch, though. Only about half of the keyboard has TMR sensors. The entire right side of the board cannot use magnetic switches or any of the advanced features. This is a strange and frustrating limitation. Logitech gave users a highly customizable keyboard and then made half of it non-customizable. It is a generational blunder on an otherwise solid product.

The keyboard also worked natively with a few other magnetic switches tested, which is a nice bonus. The integration between mechanical and magnetic switch swapping is smooth, and the auto-scan button makes the process painless.

Software and RGB Customization

Logitech’s G Hub software is already familiar to anyone who uses Logitech mice. The G512X pops right up when plugged in, and customization is straightforward. You can adjust RGB colors, set per-key lighting, and even control individual LEDs on the light bar. The macro layers are a bit confusing for most users and could definitely be improved, but the overall software experience is on par with some of the best in the industry.

For beginners, the software is particularly welcoming. Upon plugging in the keyboard, the software walks you through a series of helpful tips about the board’s features. This makes the G512X a genuinely beginner-friendly option for anyone new to mechanical keyboards or advanced features like rapid trigger.

The RGB lighting itself is some of the brightest available. Even in a well-lit room, the glow shines through the keycaps and the light bar with impressive intensity. You can set it to any color, and the per-key customization extends to the light bar, which is a nice touch.

One feature that falls flat is the multi-action snap. This uses small rubber O-rings that you place around a switch to create a second trigger point. In theory, this makes a linear switch feel tactile. In practice, it just makes the switch feel mushy and less responsive. It is a creative idea that does not work well in execution.

Buying Advice

The Logitech G512X is priced at $179.99 for the 75% version. That is competitive when compared to other TMR keyboards like the Wooting at around $200. However, if you do not care about flashy gamer features, there are better-value options. The SK75 TMR is available for $110, and the Mongeeek M1V5 is $160. Both of those keyboards are arguably better in terms of build quality and sound, though they lack some of the G512X’s creative features.

For the price, the G512X offers a lot of unique functionality. The TMR sensing, hot-swappable magnetic switches, and strong software make it a compelling option for gamers who want to experiment with advanced features. The main drawbacks are the plastic build, mediocre keycaps, and the baffling decision to only support TMR on half the keyboard.

If you are willing to invest time in replacing the switches and keycaps, the G512X can become a genuinely good keyboard. As it ships, it is a solid but imperfect product that shows Logitech is finally moving in the right direction.

Conclusion

The Logitech G512X is a creative and ambitious keyboard that stands out in a crowded market. It brings TMR technology, hot-swappable magnetic switches, and a clever design to a segment that often plays it safe. The plastic build and cheap-feeling keycaps hold it back, and the half-keyboard TMR limitation is genuinely frustrating.

Despite those flaws, the G512X is a good keyboard with real potential. The software is strong, the RGB is impressive, and the ability to swap between mechanical and magnetic switches is genuinely innovative. For gamers who want to explore advanced features without paying Wooting-level prices, this is a worthwhile option. Logitech has taken a meaningful step forward, and it will be interesting to see where they go from here.
