News Analysis Logitech’s G512 X keyboard finally makes adjustable actuation feel practical The Logitech G512 X comes in two sizes, two colors, and two hot-swap switch options: standard and TMR for adjustable actuation.

Logitech gaming keyboards don’t agree with me. I think they’re too expensive for too little functionality, pretty much all the way across the line. But the company is doing its darnedest to change my opinion. The new Logitech G512 X keyboard goes all in on performance, whether you want standard MX switches or adjustable actuation, all without throwing in a tiny little screen. The Logitech G512 X comes in almost-full-size (1800) and 75% sizes, both using full-fat switch designs, no low-profile stuff here. These are designed for a r/battlestation setup that seeks no forgiveness. At first glance, it’s clear that Logitech is going for a much more in-your-face “gamer” look than the clean blacks and whites of other G-series keyboards. Company reps described it as “cyberpunk” in a presentation, and yeah, I see it. The black models get purple accents and the white ones get teal, both with a gigantic RGB strip down the sides and all the way across the front. That gigantic front light panel will also illuminate a translucent wrist rest for an even bigger light show, though sadly you’ll need to buy it separately. Logitech Furthering its unapologetic gamer chops, this design is wired-only, no wireless options. That makes sense with the TMR sensors (tunnel magneto resistance, an alternative to Hall effect for adjustable actuation), 8,000Hz polling, and big RGB lighting, all of which would chew through a battery like nobody’s business. But the adjustable actuation isn’t on all the switches—only 39 of them, including the spacebar. The TMR switches end at 7/U/J/M on each row, basically whatever you can reach with your left hand, plus the arrow cluster. This is smart, both for practical reasons (who needs 50 points of sensitivity on Page Up?) and for cost savings. Logitech The design also gets rid of one of the biggest weaknesses of adjustable actuation keyboards: limited hot-swap functionality. This keyboard offers standard hot-swap sockets that are compatible with the hundreds of MX-standard switch choices, plus Gateron TMR switches. This is something I’ve only seen elsewhere on the Glorious GMMK 3. To offer even more options, Logitech is throwing in what it calls SAPP (Second Actuation Pressure Point) rings. These little silicone(?) rings for the switch stem give you a tactile bump that makes it easier to sense where a secondary switch point is, at least if you configure it right. It’s an intriguing idea, one that could sell me on adjustable actuation for real functionality… if it works the way Logitech says it does. We’ll see. The keyboard has some other novel touches, including tactile or linear MX switches installed by default but…
