HMX Blue Topaz vs. Gateron CM

An in-depth look at the HMX Blue Topaz and the Gateron CM switches—which one is the best fit for you?

Overview

When choosing between the HMX Blue Topaz and the Gateron CM mechanical keyboard switches, you are presented with two distinct options. The Blue Topaz offers a smooth and lightweight typing experience with a clacky sound signature, making it ideal for those who prefer easy-to-press keys. On the other hand, the CM stands out with its full nylon housing and factory lubrication, providing a rich and deep typing sound that is complemented by a bouncy typing experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

In comparing the housing materials of the HMX Blue Topaz and the Gateron CM, we can see that while the Blue Topaz uses a polycarbonate top housing for a sharper and crisper sound profile, the CM utilizes a nylon top housing for a deeper and fuller sound profile. The polycarbonate top housing of the Blue Topaz is known for its stiffness, which contributes to a clear and resonant sound profile, making it ideal for switches with RGB lighting. On the other hand, the nylon top housing of the CM is softer and absorbs more sound, resulting in a duller and rounder sound. Despite these differences, both materials offer unique sound profiles that cater to different preferences.

When it comes to the bottom housing materials of the Blue Topaz and the Gateron CM, both switches utilize nylon for a deeper and fuller sound profile. The softer nature of nylon allows it to absorb more sound, creating a duller and rounder sound compared to harder plastics. This similarity in bottom housing materials means that both switches provide a consistent typing experience in terms of sound and feel. While the top and bottom housing materials play a role in the overall sound profile of a switch, the similarity in nylon bottom housing ensures that the typing experience remains consistent regardless of the switch being used.

Overall, the choice between the HMX Blue Topaz and the Gateron CM comes down to personal preference in sound profile. The Blue Topaz offers a sharper and crisper sound profile due to its polycarbonate top housing, while the Gateron CM provides a deeper and fuller sound profile with its nylon top housing. Both switches use nylon for their bottom housing, resulting in a similar typing experience in terms of sound and feel. Whether you prefer a brighter, more resonant sound or a deeper, fuller sound, both switches offer unique qualities that cater to different preferences in the world of mechanical keyboards.

Weight

The actuation force and bottom out force of the HMX Blue Topaz linear switch and the Gateron CM linear switch have notable differences. The Blue Topaz has a lighter actuation force of 40 grams compared to the CM's heavier 55 grams. Similarly, the bottom out force of the Blue Topaz is lighter at 48 grams, while the CM has a heavier bottom out force of 63.5 grams. The lighter forces of the Blue Topaz make it ideal for those who prefer a lighter typing experience for extended periods, such as for work or gaming. On the other hand, the heavier forces of the CM provide a more substantial typing feel for those who prefer a stronger push. Both switches offer different weight options to cater to varying preferences, ensuring that users can achieve their desired typing experience.

Travel distance

When comparing the travel distance of the HMX Blue Topaz linear switch and the Gateron CM linear switch, it is evident that the Blue Topaz has a longer travel distance of 3.9 mm compared to the CM's 3.6 mm. The Blue Topaz provides a tad more depth when pressing down on a key, which may appeal to those who prefer a more substantial feel. On the other hand, the CM offers a slightly shorter travel distance, which may be favored by gamers looking for faster response times. Ultimately, the decision between the two switches depends on personal preference - whether you prioritize a deeper press with the Blue Topaz or a quicker response with the CM. Regardless of the choice, both switches offer a similar experience in terms of travel distance within the range of 3.6 mm to 3.9 mm.

Typing experience

In terms of sound, the HMX Blue Topaz linear switch offers a clacky sound, producing a sharp and snappy noise with each key press. This sound is crisp, bright, and percussive, adding a tactile element to the typing experience. On the other hand, the Gateron CM linear switch provides a bassey, thocky, and low-pitched sound profile. The deeper and richer sound of the CM switch offers a more resonant and satisfying auditory experience compared to the Blue Topaz. It's important to note that the sound of a switch can also be influenced by factors like the keyboard's construction and the type of keycaps used.

When it comes to the feel of the switches, the HMX Blue Topaz linear switch is described as easy-to-press, offering gentle resistance and requiring minimal force to activate. This light actuation force makes typing effortless, comfortable, and reduces finger fatigue during extended typing sessions. In contrast, the Gateron CM linear switch provides a buttery, polished, creamy, and frictionless typing experience. These qualities result in a smooth and fluid keystroke, with reduced friction and a polished finish that enhances the overall typing sensation. The CM switch promises a gliding sensation with each key press, evoking a sense of ease and grace in typing.

Taking all the available information into consideration, if you value a clacky sound and lightweight, easy-to-press feel, the HMX Blue Topaz linear switch would be your top choice. However, if you prefer a richer, deeper sound profile and a buttery, polished typing experience, the Gateron CM linear switch would be the ideal option for you. Ultimately, both switches offer unique qualities that cater to different preferences and typing styles, ensuring a personalized and enjoyable mechanical keyboard experience.

Conclusion

To sum up, when deciding between the HMX Blue Topaz linear switch and the Gateron CM linear switch, consider your preferences for typing experience. If you prioritize a smooth and lightweight feel with a clacky sound, the Blue Topaz may be the ideal choice for you. On the other hand, if you prefer a deeper and richer sound with a bouncy typing experience and a buttery, polished feel, the Gateron CM switch would be more suitable. Ultimately, your decision should be based on whether you value the light actuation force and distinctive glitter housing of the Blue Topaz, or the full nylon housing and impeccable factory lube job of the Gateron CM. Happy typing!
