Logitech G512 X 98 Review: The hybrid concept doesn't convince at a premium price

With the G512 X 98, Logitech dares a new approach: classic mechanical and analog TMR switches on a keyboard. The dual-switch bed concept sounds exciting - but disappoints on several levels.
Logitech G makes great mice. However, I've been avoiding their keyboards for years. The G915 was once my entry into the world of mechanical keyboards. But the deeper I delve into the subject, the less I like the manufacturer's keyboards. I don't like typing on them because the switches and acoustics don't suit my style. It's gotten to the point where I've even completely disassembled and reassembled them. I've also been waiting a long time for real innovations.
With the G512 X 98, Logitech at least surprises in this regard. The keyboard combines classic mechanical with TMR switches. This works, but isn't entirely convincing.
Two models, one concept
The G512-X series offers two variants: the G512 X 98, which I'm testing, and the G512 X 75. Both models share the same functions and differ only in size. The 98 percent model is very close to the full-size format – numpad, arrow keys, and function row are present, all in a slightly more compact housing. The 75 percent model omits the numpad and is more compact than a TKL layout. Both keyboards are wired only, but offer a polling rate of up to 8000 Hertz.
The scope of delivery includes the keyboard, nine TMR switches, five SAPP rings (Second Actuation Pressure Point), five additional keycaps, a USB-C to USB-A cable, and two pullers that can also be used as feet for tilt adjustment.
Cool idea: I adjust the typing angle with the keycap and switch puller.
The hybrid concept: interesting, but half-hearted
The central idea of the G512 X 98 is the combination of classic mechanical and analog TMR switches. Logitech calls this Dual-Switch-Bed. The TMR switches allow variable actuation points and rapid trigger – real advantages in competitive gaming. Once set up, it works perfectly.
The catch: Not the entire keyboard is TMR-capable. Only the left half, the spacebar, and the arrow keys have TMR sensors – a total of 40 keys. This is enough for many, but prevents fully analog operation. Even more serious: Of these 40 possible TMR positions, only nine switches are included. This is enough for WASD, spacebar, and four other keys of your choice.
In competitive gaming, TMR switches can give you the decisive advantage.
One advantage of analog switches is that the actuation point can be raised on less used keys to avoid accidental inputs. With only nine switches, this is hardly feasible.
In addition: Mechanical and analog switches feel different. This leads to an inconsistent typing feel – both when writing and when playing. Theoretically, the switches can be swapped at any time. In practice, I don't do that. Logitech should have included two complete switch sets and extended TMR to all keys.
Horrible mechanical, smooth TMR switches
The built-in mechanical switches are tactile and provide haptic feedback when actuated. They don't feel good. The actuation feel is too weak, the switches feel scratchy. Acoustically, it's also not convincing.
The mechanical compared to the TMR switches. With the latter, you can see the magnet in the middle, which is used for distance measurement.
It's a shame, because the TMR switches show that it can be better. They are linear, so they don't give feedback when actuated. This is suitable because the actuation point can be freely adjusted. The switches manufactured by Gateron run smoothly and sound much more pleasant than Logitech's in-house ones. It's all the more regrettable that only nine pieces are included.
The stabilizers that support the long keys are among the worst I've experienced in recent years. They rattle and clatter, making pressing the spacebar no fun. Other manufacturers are doing better now. Logitech needs to improve here.
Software and performance
Configuration is done via Logitech G Hub. Profiles, key assignments, RGB effects, and analog switch settings – everything is available and works reliably. I can set the actuation point between 0.1 and 4 millimeters, and activate Rapid Trigger in 0.1-millimeter increments. SOCD options, i.e., the behavior when simultaneously pressing opposite directions, are also included.
In the software, you can immediately see: Not all keys are TMR-capable.
Design: Gaming aesthetics
Logitech relies on a distinct gaming look for its design. I don't like it, but I'm not the target audience either. You can choose between black with purple accents or white with turquoise details.
An RGB strip is located on the front. A transparent wrist rest can be attached in front of it, which is available separately for around 40 francs / euros – the light spreads effectively on it. It looks good at night, but the effect is less impressive during the day. The rest is not attached to the housing, but only slides into a narrow groove.
The optional wrist rest glows impressively.
The keycaps are made of PBT plastic, which is considered durable and absorbs fewer fingerprints than ABS. Logitech made the right decision here. The primary legends are created using double-shot molding and should never fade. The legends light up well, at least the upper ones. The lighting is not sufficient for the lower ones. The third functions are printed on the front of the caps.
Logitech does everything right with PBT plastic for the keycaps.
Workmanship: Plastic at a premium price
The housing is made entirely of plastic. In the bend test, the keyboard noticeably flexes – this is disappointing in this price range. Competitors with at least partially aluminum housings are clearly ahead here. For the price, it feels too cheap.
On the top right are two rotary controls: one for RGB brightness, one for volume. Both can be configured via Logitech software. They feel inferior. The edges are sharp, they wobble.
The rotary controls don't feel good.
On the underside, the included keycap and switch pullers can be inserted as feet. This is original, but hardly more practical than classic folding feet. On the back there is a compartment for up to nine switches, so I can quickly swap them, and a slot for the five SAPP rings.
The rubber rings for adjusting the key travel can easily get lost.
These rubber rings can be placed on the keys to shorten the key travel to two millimeters – this allows me to trigger a secondary action if I press the key further. This gives me physical feedback for double assignments. At least in theory. In practice, I hardly feel it and it takes a long time to get used to it. The benefit remains hidden from me anyway. I'd rather train my fingertip feel without rubber, especially since the typing feel suffers. Besides, the rings are easily lost.
In a nutshell
Good idea, half-hearted implementation
The Logitech G512 X takes an interesting approach – combining classic and analog TMR switches in one keyboard. However, in practice, the hybrid concept makes too many compromises: the casing is made entirely of plastic, TMR is only possible on 40 keys, and with only nine included TMR switches, the potential remains largely untapped.
For 100 francs / euros less, the G512 X 98 would be an interesting entry-level model for analog gaming. For over 200 francs / euros, there are simply better alternatives. Keychron, for example, offers a fully TMR-capable, wireless model with the K2 HE that is cheaper.
Pro
- TMR Switches
- well-thought-out details
- 8000 Hz polling rate
- PBT Keycaps
Contra
- Plastic housing
- TMR only on 40 keys and only nine switches included
- poor value for money
