Corsair K70 vs Razer Blackwidow

You are ready to get a dedicated gaming keyboard, but end up confused in between Corsair K70 and Razer Blackwidow. Both are high-quality gaming keyboards standing in the same price range. Both manufacturers, Corsair and Razer, are well-known names across the gaming industry, so we can’t underestimate their products. Corsair K70 is loved by many because of the ultra-rugged build and great customization features. Meanwhile, Razer Blackwidow is a renowned weapon for various games because of the Chroma software and five additional macro keys. Let’s see the more detailed comparison below.

Design and Construction
Corsair K70 is quite heavier than Razer Blackwidow. This is because Corsair K70 features aircraft-grade anodized aluminum housing and key caps. Such construction is extremely rugged and durable. For sure, it can take a blast and survive. The design also makes this keyboard easier to clean. It is bulkier because of the wrist rest, but the wrist rest is detachable. On the other hand, Razer Blackwidow is quite more lightweight because the housing has a lot of plastic parts. Being more lightweight means better portability. But the plastic housing is not as durable and not as easy to clean. In addition, Razer Blackwidow is slightly wider than Corsair K70 because of the additional macro keys.

Wrist Rest vs. Macro Keys
Next, let’s consider the special features of both keyboards. The special feature of Corsair K70 is the detachable wrist rest. The wrist rest is very soft and comfortable, and, being detachable it should not be a problem for storage and travel. If you often experience wrist pain after some time using a keyboard, the wrist rest would be very useful. There are also on-board media controls with a dedicated volume knob.

Razer Blackwidow comes with five additional macro keys that you can use to assign specific game commands for quick access. Depending on your preference and the game that you play, these hot keys can be very useful. They allow you to easily re-map buttons and quickly access important commands. But if you rarely need to re-map buttons or access complex commands, they will not bring you much benefit.

Both models are fully customizable, including the backlight systems. On Corsair K70, you can create multiple profiles for different games with each own macro and backlight settings. Razer Blackwidow boasts the Chroma software, which enables games to customize the backlight system to correspond with in-game events. Seeing the keyboard blinking dangerously when encountering a boss is awesome.

Performance
Since both Corsair K70 and Razer Blackwidow are mechanical keyboards, they are fully resistant to ghosting, ensuring the ultimate input accuracy and precision. However, they use different switches, so they may have different characteristics. Corsair K70 is available with Cherry MX Blue, Brown, and Red switches. The Blue is the clickiest and most tactile; the Brown is slightly less clicky; the Red is the quietest and softest, equivalent to Razer Blackwidow Stealth. On the other hand, Razer Blackwidow is equipped with Razer Green and Razer Orange switches, which are slightly faster to register but not very comfortable for typing.
