Compared to the Logitech G305, the Razer Viper Mini is the faster and better gaming mouse for gamers who want top-tier performance. While the G305 is still fast and reasonably lightweight, the Viper Mini takes it to another level with low click latency and superlight weight. Otherwise, the Viper Mini and the G305 are similar, especially their nearly identical dimensions, but the Viper Mini is wired, and the G305 runs wirelessly via a USB receiver.

The key performance differences between the Logitech G305 and Razer Viper Mini are the weight and sensor DPI.
Sure, the G305 offers an additional polling rate selection of 250 Hz and tracks accurately at 400 inches per second, compared to 300 inches per second for the Razer Viper Mini. But these features aren’t critical for most gamers, hence giving those features little additional commentary here.
The Razer Viper Mini is better if lightweight performance is essential. The Viper Mini is 25% lighter than the G305, making it significantly snappier in fast-paced titles and helping it glide more smoothly on a mousepad.
However, the Logitech G305 has a wider DPI range with the Hero sensor that maxes out at 12,000 DPI. Neither models are the best gaming mouse if you want the highest DPI sensor – you’ll need to jump up in price to get sensors with a 30,000 DPI.
But let’s put the DPIs in context for a moment. Few gamers play at over 2,000 DPI, so much more than that level is overkill in many scenarios. Plus, Logitech and Razer mouse sensors are highly accurate compared to many gaming mouse brands.
Battery Life (hours)
USB Receiver Storage
The Logitech G305 runs wirelessly with the included USB receiver, whereas the Razer Viper Mini is wired.
In our reviews of both models, the wired connection on the Viper Mini gives it a considerable click latency advantage of two to three milliseconds over the G305. However, this isn’t always true when comparing a wired gaming mouse to a wireless model over a 2.4 GHz connection.
Unlike most gaming mice that run off of a AA battery, the Logitech G305 doesn’t include Bluetooth. The added versatility is helpful for using your mouse without a USB receiver.
But it makes sense why Logitech skipped Bluetooth with the G305 since this is a performance-oriented gaming mouse where cutting weight and latency is more important. Bluetooth is a slower transmission protocol than Logitech’s Lightspeed 2.4 GHz connection, and adding Bluetooth connectivity would increase the weight.

The Logitech G305 and Razer Viper Mini are commonly compared, and it makes sense why when reviewing their designs. Both have almost identical dimensions – the G305 is a few millimeters wider and shorter than the Viper Mini.
As is typical with FPS gaming mice, the G305 and Viper Mini have a familiar six-button layout with two buttons on the left side and a button behind the scroll wheel.
You notice minor shape differences between the two models when holding them. Notably, the Viper Mini has slight recesses on each side that improve gripping power with some grip styles, and the G305 has more of an egg-like shape and no side recesses.
Consider the Logitech G305 if you want something to accessorize your setup. The G305 comes in several vibrant colors, such as mint and blue, while the Viper Mini is available only in black.
Software and customization
There are a few differences between the Logitech G305 and Razer Viper Mini regarding the customization and software capabilities, though whether each difference matters depends on the gamer.
Logitech gaming mice have full Windows and macOS compatibility. The Razer Viper Mini works in macOS, though you’re limited to the default settings or whatever you customize in Synapse on a Windows machine and then save to one of the onboard profiles.
The Razer Viper Mini has one RGB zone, powering lighting in the logo and on the back underside.
Lastly, the Viper model has more programmable inputs. The Viper Mini has 14 total programmable inputs using HyperShift layers in Synapse, whereas the G305 has 11 programmable inputs using G-Shift in G-Hub. The Viper Mini has more programmable inputs since the scroll wheel up/down action is programmable.
One last feature that differentiates the two gaming mice is the onboard profiles. You can carry onboard up to five saved profiles and only one with the G305. The limited profile options are one area where Logitech sacrificed to bring down the price.
Multiple onboard profiles are convenient if you use different DPIs or profiles for specific games or roles within a game, enabling you to cycle through profiles on the fly, which you can’t do with the G305.
