Keychron Lemokey X1 vs Lemokey X480% vs 75% Layout & Mount Style Comparison

The primary differences are layout and mounting. The X1 uses an 80% (tenkeyless) layout with a tray mount and steel plate. The X4 uses a more compact 75% layout with a gasket mount and polycarbonate plate. The X4 also adds knob support.

The X1 is generally better for programming. Its 80% layout includes dedicated navigation keys like Insert and Delete, which are frequently used in code editors. It also supports VIA software for quick key remapping without needing to compile firmware.

No. Both the Lemokey X1 and X4 are wired-only mechanical keyboards. They connect via a USB Type-C cable and do not offer Bluetooth or 2.4GHz wireless options.

Yes. Both keyboards feature hot-swappable sockets, allowing you to easily change the mechanical switches without soldering. They are compatible with most 3-pin and 5-pin mechanical switches.

The Keychron X4 is more portable. It is lighter at 712 grams compared to the X1's 837 grams, and it has a shorter length (325mm vs 357mm) due to its 75% layout, making it easier to transport.

According to the listing, the X4 offers two keycap options. One uses OEM profile double-shot ABS keycaps. The other uses Cherry profile, side-printed, double-shot PBT keycaps, providing a different typing feel and material.

The vendor description for the X4 does not list VIA support. It is programmable via QMK open-source firmware and the Lemokey Launcher web app. The X1 explicitly supports both QMK and VIA.

Both the Keychron X1 and X4 have a 1000 Hz polling rate. This is a standard high-performance rate for gaming and ensures low latency for keypress registration.

Both the X1 and X4 use screw-in stabilizers. This type of stabilizer is preferred by modders as they are typically more stable and rattle less than clip-in stabilizers, and they are easier to remove for lubrication.

Yes, both are suitable for gaming. They share a 1000 Hz polling rate for fast response, N-key rollover to prevent ghosting, and are wired for a reliable connection. The choice between them for gaming comes down to layout preference.

While the full contents aren't detailed, both product listings mention they come with a USB Type-A to Type-C cable. They are pre-built keyboards, so they include the assembled board with keycaps and switches installed.

The X1 uses a tray mount, where the plate is screwed directly into the bottom case, often resulting in a firmer typing feel. The X4 uses a gasket mount, where the plate is suspended on rubber or silicone gaskets, which can reduce case vibration and create a softer, more flexible typing experience.
