Logitech G915 vs G613 Wireless Full Keyboards

Both Logitech G915 and G613 are 109-key, wireless keyboards that are capable of a 1ms report rate that matches wired keyboards. The wireless speed is achieved by using their Lightspeed USB wireless dongle, while Bluetooth is also available but at a slower report rate of 8ms.

A key advantage of the G915 vs G613 is that you can select other types of keypress – clicky, tactile or linear.

  • Linear switch has a smooth operation with no feedback, which makes them ideal for MMO, fast double-tapping and rapid keystrokes. They are also the quietest among the three types of switches.
  • Tactile switch provides subtle feedback at the actuation point (1.5mm), and is preferred for competitive and FPS gaming.
  • Clicky is similar to tactile feedback but also has an audible sound like traditional gaming switches.

Logitech’s GL switches are also low profile and have a shorter total travel of 2.7mm when compared to Romer-G tactile L with a 3.2mm travel distance. The GL switches are not designed to be user-replaceable although some users commented that it is possible to get replacement keys from Logitech or a third party. For first time buyers, they will need to select from either one of the three types of switches.

For those who prefer to have user-swappable, mechanical key switches, Logitech offers the Pro series with Logitech GX switches.

  • GX Red is the linear switch that has a smooth operation with no feedback.
  • GX Brown is the tactile switch that gives subtle feedback at the actuation point (1.5mm), and is preferred for competitive and FPS gaming.
  • GX Blue is a clicky switch that is similar to tactile but also has an audible sound.

Although GX keys are swappable, they have a longer actuation distance of 1.9-2mm, and a total travel of 4mm, which are both significantly more than GL keys. And even though the switches are swappable, the Logitech PRO keyboard is sold with GX Blue as the standard which means users will get the audible click option. So for users who prefer the GX Brown or GX Red will have to buy separately:

For those who prefer tactile switches, the advantage of the Logitech G613 vs G915 is the Romer-G Tactile which has a lighter keypress of 50gf (tactile). Romer-G also has a 40% longer lifespan than GL switches, so it can theoretically last very long.

Those who prefer lower profile keys and more choice switches should pick Logitech G915.

BacklightingNoYes

For those who are familiar with keyboard design would have noticed that the power source would determine if backlighting is available. In most cases, high-end keyboards with backlights are often powered by a rechargeable Lithium Polymer battery.

The G915 keyboard has a stated battery life of 30 hours at 100% backlight brightness, which could last a week based on approx. 4 hours gameplayer per day. In most cases, it is best to keep the keyboard plugged into the charger rather than worrying about dying in the middle of a gunfight due to a low battery. The micro-USB connector is technically fine for charging purposes, but for the G915 price, it should be getting USB Type-C like the Craft and MX Keys.

There are no complaints about the G613 though as it has no backlighting, which means AA batteries can last very long up to 18 months. However, the battery life is mainly for Bluetooth (low energy) while Lightspeed wireless will consume more power like the Logitech G604 mouse.

So when comparing G915 vs G613 battery life, G613 is a clear winner if you do not need the backlit light.

For the G604 mouse, it has 5.5 months of battery life in Bluetooth mode, while Lightspeed wireless gets only 240 hours of battery life. Assuming the same ratio of battery life, the G915 could be getting about 75 hours only when using Lightspeed wireless connectivity. That is the fair price of getting a 1ms report rate via a wireless connection.

The G915 has clearly more macro and functions available, although it shockingly loses out to G613 with one less programmable G-Keys. That is not a big deal unless your game needs that extra G-key.

One thing about the design that is worth commenting on is the 26 plus maximum key roll-over. For those who are not familiar with “key roll-over”, please check out the video below which also teaches you what is ghosting.

After watching the videos above, you would also wonder if anyone would use up to 10-key rollover in the G613. It is still possible to have a 10-keys rollover since we all have 10 fingers, but how are expected to use up to 26 keys rollover unless we press down on the keyboard with both palms.

The Logitech G915 has a lower profile, is lighter and significantly smaller than the Logitech G613 due to the lack of palm rest. If you are travelling around for gaming with a 109-keys keyboard, then Logitech G915 could be suitable due to the relatively lower weight even though 1kg is nowhere “light”.
