What will you mostly use it for?
The Q3 leads for programming, modding, and content-creation workflows because of its QMK/VIA support and programmable knob. Its wired connection and stated 1000 Hz polling rate also make it the more straightforward pick for gaming based on the listed connection details. The K8 is the more travel-oriented choice, with Bluetooth and substantially lower listed weights. For office use, its ability to connect to up to three Bluetooth devices gives it the edge for switching between setups.
Pick the Keychron Q3
- The Q3 specifies a 1000 Hz polling rate and wired-only connectivity.
- The K8 supports 1000 Hz when wired, but its vendor description lists 90 Hz over Bluetooth.

Keychron K8 vs Q3: your questions
Yes. The K8 supports Bluetooth and wired USB-C connectivity, and the vendor says Bluetooth can connect to up to three devices.
No. The Q3 is listed as wired-only, with Type-C connectivity, so it does not provide the K8's Bluetooth and battery features.
The K8 is lighter based on the listed weights: 740g for its plastic frame or 887g for its aluminum-bezel version. The fully assembled Q3 is listed at 2000g.
Yes. The K8 has a 4000mAh battery, and Keychron lists up to 68 hours for one backlight-off configuration and up to 240 hours with the backlight off. Battery life varies by version and lighting use.
The Q3 is listed with QMK and VIA support, including key remapping and macros through Keychron Launcher. The K8 metadata does not list QMK or VIA support.
Both keyboards have hot-swappable versions. The Q3 supports 3-pin and 5-pin MX mechanical switches, while the K8's mechanical hot-swappable version supports most MX-style 3-pin and 5-pin switches.
Some Q3 configurations include a programmable knob. Keychron describes assigning it controls or macros for tasks such as zooming, adjusting volume, and selecting video clips or photos.
The Q3 is a wired-only keyboard with a listed 1000 Hz polling rate. The K8 also lists 1000 Hz in wired mode, while its vendor description lists 90 Hz over Bluetooth, so wired use is relevant when comparing them for gaming.
The K8 is listed as tray-mounted. The Q3 uses a gasket mount, and Keychron describes a double-gasket design with silicone pads between the top and bottom cases.
Both are listed with RGB options. The Q3 has south-facing RGB, while the K8 vendor describes adjustable RGB backlighting on applicable versions.
Yes. Both have an 80% layout, which is a tenkeyless format without a numpad. Keychron describes the K8 as retaining function, navigation, and multimedia keys.
The K8 is the more travel-oriented option because it offers Bluetooth and has lower listed weights than the 2000g assembled Q3. The Q3 is wired-only and built with a full aluminum case and steel plate.
