ATTACK SHARK X68 HE vs Keychron K3 V3: your questions
The Attack Shark X68 HE is designed for competitive gaming. It features an 8000 Hz polling rate, Hall effect magnetic switches with adjustable actuation, and a Rapid Trigger function, which the manufacturer states enables a 0.125ms response time. The Keychron K3 V3 has a 1000 Hz polling rate in wired mode.
Yes. According to Keychron, the K3 V3 supports Bluetooth 5.2 and can connect to up to three devices wirelessly. This allows for seamless switching between a laptop, phone, and tablet. It also includes a wired USB-C connection.
No. The Attack Shark X68 HE is a wired-only keyboard, connecting via a USB-C cable. This contributes to its heavier 950g weight compared to the wireless Keychron K3 V3 at 540g.
The Keychron K3 V3 offers far deeper software customization. It supports open-source QMK and VIA firmware, allowing for extensive key remapping, layering, and macro programming through the Keychron Launcher web app. The Attack Shark X68 HE's listing does not mention comparable software support.
Both keyboards are hot-swappable, but with different compatibilities. The Attack Shark X68 HE is compatible with N-pole downward magnetic switches. The Keychron K3 V3's hot-swappable version is compatible with Keychron Milk POM or Gateron/Keychron low-profile mechanical switches only.
The Keychron K3 V3 is more portable. It is significantly lighter (540g vs 950g), thinner (19mm height), and offers wireless Bluetooth operation, so you don't need to pack a cable. The Attack Shark X68 HE is heavier and requires a wired connection.
Yes, both keyboards list support for Mac and Windows operating systems. The Keychron K3 V3 specifically includes extra keycaps for both macOS and Windows layouts to facilitate switching.
The Attack Shark X68 HE uses an aluminum case. The Keychron K3 V3 uses a combination of an ABS case with an aluminum frame, making it lighter but potentially less rigid than a full aluminum construction.
Yes, the Keychron K3 V3 is a low-profile keyboard with an adjustable typing angle. Keychron lists three adjustable angles: 2.5°, 4.2°, and 6.5°. The Attack Shark X68 HE has a standard profile height.
The Keychron K3 V3 includes several pre-installed foam layers for sound dampening, according to its description. It lists IXPE acoustic foam, EPDM foam, and latex foam. The Attack Shark X68 HE's vendor description does not mention included sound-dampening foam.
Both keyboards have RGB backlighting with shine-through keycaps, but the LED placement differs. The Attack Shark X68 HE uses south-facing RGB LEDs, while the Keychron K3 V3 uses north-facing RGB LEDs. The K3 V3's keycaps are specifically described as LSA profile shine-through ABS.
