Corsair K70 Core vs Keychron K5 V2Wired Gaming vs Wireless Custom

The Keychron K5 QMK V2 is designed for wireless use, featuring Bluetooth 5.2 to connect with up to three devices and a 2000mAh battery. The Corsair K70 Core is a wired-only keyboard with no wireless capability.

No. The Corsair K70 Core comes with pre-lubricated linear red switches soldered to the PCB. The Keychron K5 QMK V2 offers a hot-swappable version that allows you to change switches without soldering.

The Keychron K5 QMK V2 supports QMK and VIA, which are open-source firmware for advanced key remapping and macros via a web app. The Corsair K70 Core uses Corsair's proprietary iCUE software for RGB and basic key customization.

The Keychron K5 QMK V2 has a 1000Hz polling rate in wired mode, which is suitable for gaming. However, its wireless mode operates at 125Hz. The Corsair K70 Core, being wired-only, may offer more consistent performance for competitive gaming.

The Keychron K5 QMK V2 officially supports both macOS and Windows, including keycaps for both layouts. The Corsair K70 Core's compatibility is not explicitly stated for macOS in the provided information, though it may work with basic functions.

Both aim for a quieter experience. The Corsair K70 Core uses a dual-layered sound-absorbing design. The Keychron K5 QMK V2 uses multiple foam layers (IXPE, EPDM, latex) and pre-lubed switches. The low-profile switches on the Keychron may also affect the sound profile.

Both keyboards feature an aluminum frame combined with ABS plastic. The Keychron K5 QMK V2 is an ultra-slim, low-profile design, while the Corsair K70 Core has a standard profile. The Keychron also highlights redesigned stabilizers for less key wobble.

The Keychron K5 QMK V2 does not include a wrist rest in the box, but the vendor page shows compatible silicone palm rests available for separate purchase. The Corsair K70 Core does not mention an included wrist rest.

The Corsair K70 Core's capabilities for macro programming are tied to its iCUE software. The vendor description mentions onboard storage for profiles but does not detail macro functionality. The Keychron K5 QMK V2 explicitly supports macros through QMK.

The Keychron K5 QMK V2 is available with linear (red), tactile (brown), and clicky (banana) Keychron Milk POM low-profile switches. The hot-swappable version allows you to install other compatible low-profile mechanical switches later.

Both keyboards have multimedia keys. The Corsair K70 Core features a dedicated multimedia key and a customizable physical knob. The Keychron K5 QMK V2 has 12 multimedia keys, but their functionality may rely on layer programming.
