FAQ

Epomaker G84 HE vs Keychron K3 QMK V3: your questions

The Epomaker G84 HE is better suited for competitive gaming. It has an 8000 Hz polling rate, Hall effect switches with adjustable actuation down to 0.1mm, and features like rapid trigger and SOCD cleaning that are marketed for gaming performance.

Yes, the Keychron K3 QMK V3 is compatible with Linux according to its specifications. The Keychron Launcher web app is stated to work across operating systems, though some user reviews mention initial setup may require specific steps for Linux.

Yes, both keyboards are hot-swappable. However, they support different switch types. The Epomaker G84 HE uses north-facing magnetic Hall effect switches. The Keychron K3 QMK V3 hot-swap version is compatible with Gateron and Keychron low-profile mechanical switches only.

The Epomaker G84 HE has a larger 8000mAh battery capacity, which suggests longer potential use between charges. The Keychron K3 V3 has a 1550mAh battery, but the manufacturer claims up to 124 hours of wireless use with the backlight turned off.

Yes, both keyboards are listed as compatible with Mac and Windows systems. The Keychron K3 V3 includes extra keycaps for both operating systems and a physical switch to change layouts.

The typing feel differs significantly due to the switch and profile. The Epomaker uses standard-profile magnetic linear switches in a gasket-mounted, padded case. The Keychron uses low-profile mechanical switches (tactile or linear) in an ultra-slim, plate-mounted design, which results in a much lower typing height.

The Keychron K3 QMK V3 is more portable. It weighs 540g compared to 1000g, is thinner (19mm height), and has smaller overall dimensions, making it easier to pack and carry.

Yes, both keyboards have per-key RGB backlighting with north-facing LEDs. The Epomaker G84 HE uses its proprietary software for customization. The Keychron K3 V3 allows RGB customization through its QMK-powered Launcher web app, offering numerous lighting modes.

The Keychron K3 QMK V3 is available in multiple ISO layouts, including UK-ISO, German DE-ISO, Swiss-ISO, French-ISO, and Spanish-ISO. The Epomaker G84 HE uses an ANSI US layout.

The Epomaker G84 HE uses a gasket mount with five layers of dampening materials including PORON sandwich foam, IXPE switch pads, and bottom silicone. The Keychron K3 V3 features enhanced acoustic foams, specifically IXPE, EPDM, and latex foam, according to its product description.

Build materials differ. The Keychron K3 V3 uses a frame made of ABS and aluminum. The Epomaker G84 HE uses an ABS plastic case but pairs it with a polycarbonate plate and a complex internal gasket structure with multiple foams.
