Corsair
The Corsair K70 RGB PRO succeeds at something a lot of gaming keyboards get wrong: pairing genuinely fast Cherry MX Speed switches with a build quality that survives years of daily abuse. If you want a full-size wired board built for competitive play with room to spare for a numpad, the K70 RGB PRO is the answer.
Pros
- Cherry MX RGB Speed switches are exceptionally fast and consistent
- 8,000 Hz hyper-polling for near-instant input response
- PBT double-shot keycaps resist shine and wear
- Detachable soft-touch palm rest for long sessions
- Full-size layout with dedicated media controls and volume roller
Cons
- Full-size footprint takes up significant desk space
- Wired only — no wireless option on this model
- iCUE software can be resource-heavy on older systems
Design and Build Quality
The K70 RGB PRO is a substantial, confidence-inspiring keyboard. The brushed aluminum-alloy frame feels rigid with zero flex, and the detachable soft-touch palm rest makes marathon sessions noticeably more comfortable. At 1.17 kg it is not a travel keyboard, but it is built to live permanently on a desk.
Switch Feel and Typing Experience
Cherry MX RGB Speed switches have a shorter 1.2mm actuation distance than standard linear switches, which makes the board feel snappy under light presses. For typing, the reduced travel takes some adjustment if you are used to tactile switches, but for fast, repeated key presses it is hard to beat. PBT double-shot keycaps keep the legends crisp and prevent the shine that ABS caps develop over time.
Performance and Polling
The 8,000 Hz hyper-polling mode is the headline feature here — Corsair's AXON processing technology captures your input up to 8 times faster than a standard 1,000 Hz keyboard. In practice, most players will not perceive a difference over 1,000 Hz, but the consistency and reduced input jitter are measurable in tools like tests for competitive titles.
Software and RGB
Corsair iCUE handles per-key RGB, macro recording, and lighting sync across other Corsair peripherals. It is a powerful suite but can be heavier on system resources than competing software. Dynamic per-key RGB looks excellent out of the box, and profiles can be saved to onboard memory for use without the software running.
