Keychron Q1 Pro vs Q3 Ultra75% vs TKL Comparison

The Keychron Q1 Pro manufacturer description lists Bluetooth 5.1 and USB Type-C wired connectivity, with no 2.4 GHz mode mentioned. Its polling rate is listed at 1000 Hz in wired mode and 90 Hz in wireless mode. If 2.4 GHz is a requirement, the Q3 Ultra 8K is the model that explicitly lists it.

The Q3 Ultra 8K is rated at 8000 Hz in both wired and 2.4 GHz wireless modes according to Keychron. Bluetooth mode is listed at 125 Hz. That makes 2.4 GHz or wired the preferred connection for low-latency use.

The Q3 Ultra 8K lists up to 660 hours with the backlight off, and up to 200 hours at the lowest RGB brightness. The Q1 Pro lists up to 300 hours with the backlight off and up to 100 hours at the lowest brightness. Both use a 4000 mAh rechargeable battery.

The Q1 Pro runs QMK firmware with VIA and Keychron Launcher support, and it is available as a barebone knob kit. The Q3 Ultra 8K runs ZMK firmware and also works with Keychron Launcher for remapping and macros. Programmers who prefer a barebone build path will likely lean toward the Q1 Pro.

The Q1 Pro uses a 75% layout with a knob, while the Q3 Ultra 8K uses an 80% TKL layout with a knob. The Q1 Pro measures 145 x 328 mm, and the Q3 Ultra 8K measures 137 x 365 mm. The TKL frame is longer on the desk but keeps a dedicated function row and navigation cluster.

Yes, both are listed as hot-swappable for most 3-pin and 5-pin MX style switches, including Cherry, Gateron, Kailh, and Panda. Neither requires soldering for switch changes. The Q1 Pro also offers a barebone option for buyers who want to supply their own switches.

The Q3 Ultra 8K lists multiple acoustic layers, including sound absorbing foam, IXPE foam, PET film, latex bottom pad, and bottom case acoustic foam. The Q1 Pro uses a double-gasket design with silicone pads between the top and bottom cases plus a PC plate. Both are tuned for dampened sound, but the Q3 Ultra 8K documents more foam layers.

Yes, both list macOS, Windows, and Linux compatibility, and both include Mac and Windows keycaps. Each has a system toggle that lets you save separate layouts for each system. Keychron Launcher works through a supported browser such as Chrome, Edge, or Opera when connected in wired mode.

The Q3 Ultra 8K lists 1787 g plus or minus 10 g, and the Q1 Pro lists 1736 g plus or minus 10 g in its fully assembled version. Both are full aluminum boards that are meant to stay on a desk. Neither is a realistic candidate for regular carrying.

The Q3 Ultra 8K ships with pre-lubed Keychron Silk POM switches in Red, Brown, or Banana. Keychron describes them as using POM housing and stem for durability and a consistent keystroke. The Q1 Pro instead ships with Keychron K Pro switches in Red, Brown, or Banana on the fully assembled version.

The Q1 Pro uses QMK firmware, and Keychron lists VIA support alongside its Launcher web app. The Q3 Ultra 8K uses ZMK firmware with Keychron Launcher for remapping and macros. Both support macOS, Windows, and Linux according to the manufacturer.

Yes, Keychron lists a Barebone Knob option for the Q1 Pro that does not include keycaps or switches. That option suits buyers who want to choose their own PBT set and 3-pin or 5-pin MX switches. The Q3 Ultra 8K listing shown here only offers a fully assembled knob version.
