GMK104 vs GMK87 Key Specs
form factor and size
The ZMX Full-Size Wireless DIY Keyboard Kit (GMK104) features a standard 104-key layout with a dedicated number pad. This full-size design retains all function keys, arrow keys, and numeric inputs, making it suitable for office work and data entry where every key is essential. In contrast, the ZMX GMK87 80% Wireless Keyboard Kit (GMK87) offers a more compact 87-key configuration. It removes the number pad to save desk space while keeping the arrow keys and function row. The GMK104 measures 14 inches in length, whereas the GMK87 is slightly shorter at 14.4 inches but narrower at 5.8 inches compared to the GMK104's 5-inch width. You choose based on whether you need numeric input or a tighter footprint.
battery capacity
Battery life is a practical consideration for wireless keyboards. The GMK104 is equipped with a substantial 4000mAh rechargeable battery. This larger capacity supports extended usage periods on Bluetooth 5.0, 2.4GHz, or wired USB-C connections without frequent recharging. The GMK87 uses a 3000mAh battery. While still described as large-capacity, it holds 25% less charge than the GMK104. Both models support triple-mode connectivity and include a detachable USB-C cable for charging while in use. If you prioritize longer intervals between charges, the GMK104 has the advantage. The GMK87 remains efficient, but the GMK104 offers more reserve power for heavy use.
physical dimensions and weight
The physical build affects desk space and portability. The GMK104 weighs 1 pound and measures 14 by 5 by 1 inches. Its lower profile and lighter weight make it easier to move or store. The GMK87 is heavier at 1.5 pounds and has a height of 1.6 inches. It also measures 14.4 inches in length and 5.8 inches in width. The GMK87 includes a dual-stage foldable kickstand for adjustable height, adding to its bulk but offering ergonomic flexibility. The GMK104 does not mention a kickstand in its specifications. If you prefer a lighter, lower-profile keyboard, the GMK104 is the better choice. If you value adjustable typing angles and do not mind extra weight, the GMK87 provides that feature.
screen and media controls
Both keyboards feature a multifunctional smart display and a metal volume knob. The GMK104 screen allows customization of images and includes two multimedia buttons on the left to switch backlight or screen on/off. The GMK87 screen also supports image updates and adds date and time display functions. Both kits include the metal knob for volume control, providing tactile media management without software. The GMK104 emphasizes backlight/screen toggling, while the GMK87 highlights time display. Since both offer identical core media hardware, the difference lies in the specific software features enabled by the screen. Neither has a clear hardware advantage here, as both provide interactive displays and physical volume control.
switch compatibility
Both the GMK104 and GMK87 feature hot-swappable PCBs. This allows you to replace mechanical switches without soldering. Both models support 3-pin and 5-pin switch configurations. The GMK87 explicitly lists compatibility with major brands like Cherry, Gateron, Otemu, Kailh, and other MX switches. The GMK104 states support for 3-pin or 5-pin replacements but does not list specific brand compatibilities in the provided data. For practical purposes, both offer the same freedom to customize switch types. You can install almost any standard MX-style switch in either kit. This aspect is a tie, as both provide the essential hot-swap functionality for DIY enthusiasts.
mounting and lighting
Both keyboards utilize gasket mounting to reduce vibration and improve typing feel. The GMK104 uses gasket structure with silencing and cotton rubber pads. The GMK87 uses gasket material on the plate top and includes a USB storage compartment for cable management. Both feature south-facing RGB LEDs with 16 million colors and VIA programmability for custom lighting and macros. The GMK104 allows switching backlight effects via FN+|. The GMK87 allows adjustment of light speed and brightness via FN combinations. Both support Windows and macOS. The mounting styles and lighting technologies are functionally equivalent. The GMK87 adds cable storage, while the GMK104 emphasizes silencing pads. These are minor differences in implementation rather than capability.
