Royal Kludge R75 vs RK89Compact Gasket vs 80% with USB Hub

The R75 is generally better for typing. It uses a gasket mount with multiple foam layers for sound and shock absorption, and it comes with MDA profile PBT keycaps which the manufacturer states offer a comfortable experience. The RK89 uses a standard mount and ABS keycaps.

Yes, the RK89 has an innovative 89-key layout that includes a number pad. The manufacturer states it brings the number pad back compared to a TKL keyboard, saving over 30% space compared to a full-size board.

Yes, but the method and depth differ. The R75 supports QMK and VIA firmware, allowing deep remapping of any key and macro creation via a web app. The RK89 uses proprietary DIY software that, according to its listing, supports customizable key assignment and keybinding, but only in wired mode on Windows.

The R75 has a larger 4000mAh battery, while the RK89 has a 1850mAh battery. Based on capacity alone, the R75 should offer significantly longer wireless usage between charges, though actual runtime depends on usage patterns like RGB brightness.

The R75 comes with pre-lubed linear Cream switches. The RK89 offers a choice of clicky, tactile, or linear RK switches out of the box, and its package includes four replacement switches.

Yes, both keyboards are hot-swappable, meaning you can replace the switches without soldering. This also implies you can replace the keycaps with any set that matches the standard layout and stem compatibility (Cherry MX style).

The RK89 has two built-in USB 2.0 pass-through ports and a Type-C port. This allows you to connect devices like a mouse, flash drive, or security dongle directly to the keyboard, reducing cable clutter and reaching easier than the back of your PC.

No. The metadata lists the R75 with Bluetooth, 2.4 GHz, and Wired connectivity, making it a tri-mode keyboard. The vendor description title specifies 'Wired,' but the tech specs and connectivity options confirm it supports all three modes.

The R75 is more portable. It is a 75% layout, weighs 680g (compared to 1000g for the RK89), and has a smaller physical footprint. Its lighter weight and more compact size make it easier to pack and carry.

Yes, both the R75 and RK89 listings explicitly state compatibility with Windows and Mac operating systems. The R75 vendor page also lists Linux, iOS, and Android compatibility.

A gasket mount is a design where the keyboard's plate is suspended by rubber or silicone gaskets within the case, rather than being rigidly fixed. On the R75, this, combined with foam layers, aims to provide a softer, more cushioned typing feel and reduce vibration and noise.

The RK89's metadata lists 'Yes; Rgb,' but its vendor description and tech specs specify 'Blue backlighting' with 20 onboard modes. This indicates it has blue single-color backlighting, not full RGB per-key lighting like the R75.
