Hardware Review: Logitech G512 Carbon GX Blue

Back at E3, Logitech unveiled the new Logitech G512 mechanical keyboard with their brand new GX Blue mechanical switch. After having a brief hands-on with it, Logitech sent us over a unit so we could have some more time with it.

First off, my favorite thing about the Logitech G512 is the new GX Blue switch- it offers a nice, loud, click. The other switches that have been on offer with Logitech G keyboards, while mechanical, haven’t really had this loud, satisfying click that you often see (and hear) on other mechanical gaming keyboards on the market. If loud clicky keys aren’t your thing, Logitech also offers the option of getting the G512 with Their Tactile or Linear, Romer-G switches.

For those number fanatics out there, here’s the breakdown of the specs for each switch type, all of which have been tested for 70 million keystrokes:

Romer-G Tactile 
Actuation distance: 1.5mm
Actuation force: 45g
Travel distance: 3.0mm

Romer-G Linear
Actuation distance: 1.5mm
Actuation force: 45g
Travel distance: 3.2mm

GX Blue
Actuation distance: 1.9mm
Actuation force: 50g
Travel distance: 4.0mm

While the G512 doesn’t feature dedicated media keys, it does have a function key that will allow you to control your music and manage your volume settings. I normally prefer dedicated media controls like the ones that are present on my Logitech G710+, however I do appreciate that they’re here at all. The downside however is that you’re going to have a hard time seeing the secondary functions of these keys because the GX Blue switch has the lighting coming up only at the top of the key where the letters are present- the middle, sides, and bottom of they keys have no light coming up and as a result of that, these secondary functions wouldn’t be able to be illuminated. Also because of this, the shift functions also aren’t illuminated. So when you turn down your lights, you’ll clearly see your ‘1’ and “PRTSC” keys lit up, but you might have a hard time seeing the ‘!’ and “mute” elsewhere on the key.

Another feature of the G512 is…a very odd screw hole at the top of the keyboard. We couldn’t find out what this was for so we reached out to Logitech and they told us that this screw hole on the G512 was added to support attaching future custom or 3D printed accessories. So… let your imaginations come up with what you might be able to use that for.

The G512 also features Logitech’s Lightsync technology. Lightsync allows gamers to to have the lights on their keyboard and other Logitech G products coordinate not only with each other, but with various events in certain games, or with music. 

Something else that Logitech is currently working on which is worth a mention here, is their new G Hub software- which will give players the ability to not only create, but share their custom lighting profiles for Logitech G hardware for different games. As a quick idea of what the G Hub can do, one of the options allows you to select a portion (or multiple portions) of a screen, perhaps something like a health bar, and you can then map it to whichever keys you want on the keyboard. You could, in theory, use this to make the top row of keys be a health indicator. The software, which is currently in early access, has a lot of really great ideas, however it still needs some work before it’s something I would consider using.

They keyboard itself seemingly isn’t much different from Logitech’s G513. The largest difference between the two as far as we can tell, is the price point and what comes in the box. With the G512, you’ll get the keyboard- That’s it. There’s nothing else in the box. However, for basic users that just want a loud, colorful keyboard, maybe that’s all you need. Those that pick up the G513 however, will get a memory foam palmrest, gaming keycaps, and a keycap puller in the box. I wish the G512 came with a palmrest, but with there being a $50 price difference between the two, it’s obvious that Logitech meant for the G512 to be one of its more affordable keyboards.


Overall, the G512 Carbon GX Blue is a great choice if you want some clicky keys while staying in the Logitech G family of Lightsync keyboards. At $99.99 it’s one of the cheaper Lightsync offerings between the $69.99 G213 and the PRO at $129.99. If you’ve been waiting for Logitech G keyboards with a nice clicky switch, the G512 (or G513) will definitely be something you’ll want to consider for your setup
