The Logitech G915 X LIGHTSPEED is a full-sized wireless model that continues the G915 lineup of low-profile mechanical gaming keyboards. Compared to the lineup's previous generation Logitech G915 LIGHTSPEED, this new model brings several build quality changes. These include a slightly thicker aluminum top plate and new doubleshot PBT keycaps, which typically provide better durability over ABS keycaps and aren't as prone to developing a shiny or slippery finish with extended use. Other minor changes include redesigned keycap legends and minor software tweaks, such as the ability to program macros to any key on the keyboard, not just the dedicated macro keys.
We've also reviewed the wired version of this keyboard, the Logitech G915 X. For more information, see the Differences Between Variants section.
Our Verdict
The Logitech G915 X LIGHTSPEED is an amazing gaming keyboard. It has excellent build quality overall with a rigid and premium-feeling brushed aluminum top plate. It also has PBT keycaps, which are generally more durable and aren't prone to developing a shiny, slippery texture with extended use. Performance-wise, it delivers remarkably low wireless latency and is very well-suited for playing games at any competitive level in any genre.
Excellent build quality.
Remarkably low latency.
Per-key addressable RGB lighting and shine-through keycaps that are easy to read in the dark.
Only decent typing quality; some noticeable key wobble and hollow-feeling stabilization.
The Logitech G915 X LIGHTSPEED is decent for office use. It has excellent build quality, and its low-profile design makes it comfortable to use without a wrist rest. It's also relatively quiet to type on and connects wirelessly via Bluetooth. Unfortunately, it doesn't support multi-device pairing, and the typing quality is only decent. as there's some minor key wobble and larger keys have a distinctly hollow feel. Also, given its low-profile design, the switches have a fairly short travel distance which, depending on your preference, may feel a bit abrupt for everyday typing.

The Logitech G915 X LIGHTSPEED is a sub-par keyboard for tablet or mobile devices, but it isn't designed specifically for this usage. That said, it has excellent build quality and Bluetooth connectivity. Unfortunately, it doesn't support multi-device pairing. We tested the full-size model, which is quite bulky and heavy. However, there's also a smaller variant of this keyboard, the Logitech G915 X LIGHTSPEED TKL, which offers slightly better portability.

Fairly heavy and bulky layout that's not very portable.
The Logitech G915 X LIGHTSPEED is good for programming. It has excellent build quality with PBT plastic keycaps and a rigid aluminum top plate.

Unlike older models in this lineup, you can program macros not only to the sets of dedicated macro keys but also to any key using the configuration software. Unfortunately, there's no support for multi-device pairing, and the typing quality is only decent with some minor key wobble and a distinctly hollow feeling on larger keys with stabilizers.

It also has full RGB backlighting with clear shine-through legends that are easy to read in the dark. It connects wirelessly with its 2.4GHz receiver or via Bluetooth.

However, there's also a smaller TKL version available.

Popular Keyboard Comparisons
The Logitech G915 X LIGHTSPEED is a capable option if you're looking for a full-size wireless, mechanical gaming keyboard with a low-profile design. It offers excellent latency performance, making it a strong choice for gaming at any competitive level, and compared to the original wireless Logitech G915 LIGHTSPEED, it introduces minor but welcome build-quality improvements, including a thicker aluminum top plate and more durable PBT keycaps. Its switches also now have standard MX-style stems, which is great if you want to customize the appearance of your keyboard with aftermarket keycaps.
However, in the broader market context, the G915 X LIGHTSPEED is relatively expensive and offers the same level of raw performance as more affordable low-profile wireless options like the Keychron K5 Max or the NuPhy Air96 V2. Additionally, it lacks some cutting-edge features found on similarly priced gaming keyboards, such as Hall-effect switches or Rapid Trigger functionality.
