As a gamer, the keyboard is an essential part of your setup. Especially in games like Geometry Dash and Fortnite, gaming keyboards play an important role. A good gaming keyboard will enhance your gaming experience and help you improve your skills.

We have seen many companies enter the gaming keyboard market in recent years, offering high-quality and innovative products. However, not all the keyboards out there can fulfill your requirements. Therefore, when it comes to choosing a gaming keyboard, you have to consider different factors and find out the right one.

Corsair is one of the most renowned mechanical keyboard manufacturing brands. The Corsair K63 and Corsair K70 are two of their most popular gaming keyboards. While both the keyboards are excellent in their own right, we will go through some of the key differences between them to help you choose the right one for your gaming setup.

As far as build quality and features are concerned, the two mechanical keyboards are very similar. The price and minor feature differences may be the only things to influence your choice.

In this article, we will review and compare both keyboards in order to give a clear answer. So without further a talk, let’s get started.

The trend of wireless gaming keyboards has been steadily growing over the past year. In order to keep up with other brands, Corsair launched its K63 wireless mechanical gaming keyboard. The keyboard uses ultra-fast 2.4GHz optimized wireless technology, which ensures a stable connection without any interferences.

Moreover, this keyboard has the same form factor as Corsair’s other tenkeyless keyboards. Due to the smaller design, you get more space for the mouse. Also, the tenkeyless form factor promotes a more ergonomic position and makes your typing more comfortable.

The keyboard comes equipped with Cherry MX Red switches that provide the ultimate performance and a high degree of accuracy. Unfortunately, this model only comes with Cherry Red Switches, so there is no room for personal preferences. However, this keyboard includes media control keys that allow you to adjust audio or video.

Moving on, those of you who also appreciate RGB backlighting like me will be disappointed by the K63. Unlike other keyboards at this price range, this keyboard doesn’t offer full RGB compatibility. It comes with only two brightness settings and blue backlighting for the keys. However, the keyboard allows you to change the lighting patterns using the Corsair Utility Engine (CUE) software.

In terms of battery life, this keyboard can stay alive for up to 20 hours on a single charge. You can extend the battery life to up to 70 hours by lowering the brightness of the backlighting. The keyboard can be charged using via the micro-USB connection.

1. Design

Among the most notable differences between Corsair K63 and K70 is the design. While the Corsair K70 is a full-size keyboard, the Corsair K63 comes in a tenkeyless design.

The standard full-size design of the K70 gives you access to all the 104 keys. On the other hand, the K63 lacks the number pad and includes 87 keys, which makes the keyboard very compact and suitable for traveling. Also, it saves your desk space and gives you more room for your mouse. Also, the design promotes a natural shoulder position.

So, if you are looking for a compact gaming keyboard then go for the Corsair K63. But if you want to grab the advantages of having a number pad then the K70 can be a good option.

2. Wired Or Wireless

If you are like me and don’t like cable drag while gaming, the Corsair K63 can be the right choice for you. It features 2.4G wireless technology which ensures better connection. Also, it can last about 20 hours on a single charge, so you don’t have to worry about charging the keyboard frequently.

However, wireless keyboards are also not without problems. In some cases, wireless keyboards are slower than wired keyboards due to lag and latency issues, which can often be a deal-breaker for gamers. In this case, the K70 is a good solution.

3. Switches

It is another important thing that may push you to buy one or the other. The Corsair K63 only comes with Cherry MX RED switches, so there is no room for your personal choice, which is a big disadvantage of this keyboard.

On the other hand, the Corsair K70 is currently offered with a wide array of switches which includes the Cherry MX Red, Brown, Blue, and RGB Speed Switches so that gamers can choose the one that matches their gameplay style.

4. Comfortability

Compared to the Corsair K63, the K70 makes a bigger difference when it comes to comfort. There is a detachable soft wrist pad on the K70 that helps prevent wrist bends and relieve wrist pain. Also, the keys are well-textured, providing you with maximum grip and a comfortable typing experience.

Both the Corsair K63 and Corsair K70 are two of the best mechanical keyboards out there. Both mechanical keyboards are meant for gamers, and both are worth owning.

If you are still confused then I would recommend that you choose the one that meets your requirements. The Corsair K63 is ideal if you have a limited budget and are willing to sacrifice the number pad. But if you have enough budget and want something sturdy with all the necessary features, the K70 is what you are looking for.

Also, both the keyboards differ in the switches, design, and comfortability. Make sure you consider everything that we have mentioned above before making a final decision.
