Testing & Results

Testing Methodology

Testing an input device is simple, all one needs to do is use it, unfortunately there are no quantitative benchmarks to run, no numbers to compare, and no software used that can test the quality of the hardware. Testing an input device like the Corsair Vengeance K70 Mechanical Gaming Keyboard is going to be based around personal opinion and preference. For instance; I really like the ability to choose which keys I want illuminated, but this is a novelty and will not be considered useful by everyone. In this section I will present my unbiased opinion with regards to the use and operation of the Vengeance K70, and report back any improvement benefiting directly by its use in various games and programs listed below. Your mileage may vary slightly and as such this should be taken as a guide only.

I have tested other mechanical keyboards prior to the Vengeance K70 but they have always featured Cherry MX Black switches. Cherry MX Red switches are so much lighter and more responsive than MX Blacks and the difference is very noticeable. This will be great for games where you will benefit from a fast response time.

There are no real gaming features to the K70 as such, really the features are all novelties. To be called a gaming keyboard, things like macro’s and bindable keys are important. Since the K70’s main features are backlit keys and replaceable keycaps, it must be aimed at novice gamers who struggle to remember the keys needed to play any given game. The per-key illumination comes in handy for illuminating just the keys for your favorite game, this is handy for low light visibility and for remembering key layouts etc. The more you look at the keyboard the less you are looking at your screen so all these novelties won’t count for much in the heat of battle.

The main problem I have with this keyboard is apparent when I am typing, maybe it’s the adjustment period of the keyboard or maybe it’s just me. I find that Cherry MX Red switches are definitely for the nimble fingered. I found myself accidentally hitting the keys next to the keys I intended to press, which results in a lot of typo’s. Caps Lock is the most frequent which is never good when typing. A slight brush stroke from a stray finger is all that is needed to actuate a keypress. It has got better with time though, so maybe I am getting used to the keys after all.
