Although Logitech and Razer are fierce rivals, the decision as to which company will triumph has now been reduced to a literal dongle measuring competition. With that said, let’s check it out how Logitech G915 Lightspeed compares with Razer Blackwidow V3 Pro.

G915 Lightspeed vs BlackWidow V3 Pro: Design

Starting with the overall construction and design these are both full-size wireless mechanical keyboards.

Blackwidow V3 Pro

The Blackwidow V3 pro weighs about two and a half pounds and has a plastic body with a metal top plate. It feels well-made and is made of durable materials. Although the top plate is a bit of a fingerprint magnet, the aesthetic is more subdued than the Blackwidow.

G915 lightspeed

The G915 lightspeed is also made of a metal top plate that is wrapped around a plastic casing, but the G915 also curves around the sides to make it look slightly nicer and to give the impression that it is entirely made of metal. Additionally, the top plate is constructed from brushed aluminium that has a sophisticated appearance and hides fingerprints. At 2.25 pounds, the G915 is a little bit lighter.

G915 Lightspeed vs BlackWidow V3 Pro: Buttons

Both of these keyboards feature a row of media-specific keys in the top right corner as extras.

Blackwidow V3 Pro

The Blackwidow V3 pro has a digital dial and four dedicated buttons. The Blackwidow V3 pro has no additional dedicated keys because Razer has recently decided to focus exclusively on their hypershift technology.

G915 Lightspeed

The G915 Lightspeed adopts the opposite strategy and adds numerous dedicated buttons. On the left side of the keyboard, there are five programmable macro keys that I personally like, four dedicated media keys, a large volume scroll wheel with a waterfall design for ease of use, eight additional dedicated buttons for on-the-fly macro recording, adjusting brightness, and switching wireless modes, to name a few.

G915 Lightspeed vs BlackWidow V3 Pro: Switch Types

G915 lightspeed

Looking at the switch options the G915 lightspeed uses what Logitech calls their GL switches, they’re essentially just Kale low profile switches and they’re actually branded as such i do like that Logitech offers three switch types on this board; a linear tactile and clicky variation.

Therefore, there will be a switch type for every preference. The low profile switches are a little bit shorter than Razer’s full-size switches but won’t feel as quick as cherry speed switches because of their 1.5 millimetre actuation distance and 2.7 millimetre total travel. Although I don’t typically like low profile switches, typing on these feels surprisingly normal.

Blackwidow V3 pro

On the other hand, there are two switch types available for the Blackwidow V3 pro: clicky green and linear yellow. In order to make their switches perform similarly to Cherry MX silence switches, Razer has improved the lube on the switches and added silicone sound dampeners on the linear variation of their switch. The absence of a tactile switch option is the only issue I have with this.

G915 Lightspeed vs BlackWidow V3 Pro: Key Caps

G915 Lightspeed

The G915 Lightspeed has painted ABS keycaps and does not have its secondary characters lit, which can be a pain in the butt when using the keyboard in the dark. The Blackwidow V3 Pro’s key caps are made of double shot ABS and have all of their secondary characters lit.

Blackwidow V3 Pro

The Blackwidow V3 pro uses a standard layout and because of the Cherry MX compatible Razer switches there are a ton of aftermarket keycap options out there. If you want to upgrade from the ABS keycaps. This simply isn’t an option with the G915 though as low profile keycaps really aren’t available as an aftermarket option right now.

Both keyboards will perform reasonably similarly in terms of lighting because they both have clear switch bodies that let more light spill out over the keyboard and because Logitech and Razer’s companion softwares allow for nearly the same level of lighting customization.

G915 Lightspeed vs BlackWidow V3 Pro: RGB Lightning

G915 Lightspeed

Although Logitech G915 Lightspeed also has a pretty cool screen sampling option, Razer does have added the advantage of having a huge selection of supported games for reactive in-game lighting effects. This feature allows the keyboard to mimic what is happening on the screen.

Blackwidow V3

The Blackwidow V3 doesn’t quite look as good at lower brightness settings, and that’s probably something you’ll have to get used to because these boards are wireless and running them at max brightness which is going to suck the battery life like crazy. So, they both have their advantages and disadvantages. Both keyboards look bright and vibrant at max lighting, though I will give the edge slightly to logitech on this one.

G915 Lightspeed vs BlackWidow V3 Pro: Battery Life

Both boards come with a cable for wired use and charging. The G915 light speed connects using the more dated micro USB, whereas the Blackwidow V3 uses the nicer USB C-Cable.

Just take a look at these examples to see how far ahead Logitech is of Razer when it comes to battery life.

You can use the G915 for 1088 hours or 136 days if the lights are off. In contrast, the Blackwidow V3 pro offers 192 hours. In other words, there is a significant difference between the G915’s 96 hours or roughly 12 days of use at maximum RGB and the Blackwidow v3 Pro’s essentially 5-8 hours.

G915 Lightspeed vs BlackWidow V3 Pro: Connectivity

Both keyboards use a proprietary form of wireless connectivity. Razer uses hyperspeed wireless which connects to the computer using the included dongle. If you feel like playing a game, the Blackwidow V3 pro also has a storage compartment for the dongle. The G915 connects using a dongle and Logitech’s Lightspeed wireless technology.

G915 Lightspeed

If it helps, both of these keyboards have very similar-sized dongles, which brings us to the proverb. The location of the dongle’s plug is more important than its size. Especially with Razer, because the connection can be a little spotty depending on where you place it in the computer, where the dongle is in relation to the keyboard in particular and how far away you are from it. Logitech doesn’t really have this problem.

Blackwidow V3

Additionally, both of these keyboards have bluetooth capabilities and can pair with multiple devices at once for convenient device switching. Honestly! In terms of wireless connectivity, I discovered both of these to be fairly dependable. The distance and location of the dongle will often determine this but in a typical desktop setup, I didn’t really notice any major problems.

Pricing & Conclusion

Both boards cost about the same and in my opinion they are slightly overpriced.

The G915 light speed is $250 while the Blackwidow V3 pro is $230 and I think for that small of a difference in price for me.

As a wireless device, the G915 Lightspeed is unquestionably the better value. I believe the G915’s design makes a lot more sense. It offers better overall lighting, a slimmer, more portable chassis, and an appreciably longer battery life, all of which are huge pluses.

For those of you who may not like low profile switches, the Blackwidow V3 Pro is an option, and it does include the wrist rest, which is nice. All things considered, if the high cost of these boards doesn’t deter you, I would suggest choosing the G915 lightspeed.
