Razer Basilisk V3 Pro vs. Razer Viper V3 Pro: Which Gaming Mouse Is Best?
Choosing between the Razer Basilisk V3 Pro and Razer Viper V3 Pro comes down to what you value.

Picking the right gaming mouse is essential because it's a virtual battle you're going to be in, and you want the best weapon. This brings the confusion of which mouse to go with: the Razer Basilisk V3 Pro or the Viper V3 Pro?
They both sit at the top of the Razer lineup, but they cater to entirely different playstyles. One is entirely featured, bricked, and built for comfort and control, while the other is a featherweight soldier designed for speed.
If you’re torn between these two premium devices, this guide will break them down in extreme detail, covering design, performance, customization, and usability, so you can decide which one serves you best.

1. Design and Build
- Razer Basilisk V3 Pro: The Basilisk V3 Pro has an ergonomic, right-handed design with a thumb rest and a more sculpted shape. This design makes it perfect for long sessions and palm grip users. It also weighs around 112g, so it is a bit heavier.
- Razer Viper V3 Pro: The Viper V3 Pro is lightweight. It is an ambidextrous shell that’s focused purely on performance and speed, and the design is built for claw/fingertip grippers. It comes in at an incredibly light 54g, making it one of the lightest wireless esports mice ever, which is no surprise considering the lightweight design.
2. Sensor Performance
- Basilisk V3 Pro: The Basilisk V3 Pro is equipped with Razer’s Focus Pro 30K optical sensor with 99.8% resolution accuracy and Motion Sync, which tracks consistently across various surfaces.
- Viper V3 Pro: The Viper V3 Pro also uses the Focus Pro 35K sensor, but it has a slightly higher DPI ceiling, refined to give FPS pros precision without compromise.
3. Buttons and Scroll Wheel
- Basilisk V3 Pro: It comes with 11 programmable buttons, including a multi-function trigger and Razer’s hyper-scroll tilt wheel for dynamic control in all genres.
- Viper V3 Pro: It keeps it minimal with 6 programmable buttons, cutting away excess to focus purely on quick clicks and low-latency responsiveness.

4. Connectivity and Battery Life
- Basilisk V3 Pro: It utilizes both Razer HyperSpeed Wireless and Bluetooth, with up to 90 hours of battery life depending on usage.
- Viper V3 Pro: It’s strictly HyperSpeed Wireless, no Bluetooth, but has an impressive 95 hours of ultra-stable connection and endurance.
5. Charging and Docking
- Basilisk V3 Pro: Compatible with Razer’s wireless charging dock and includes RGB charging indicators, a nice touch if you’re all-in on the Chroma ecosystem.
- Viper V3 Pro: Can work with Razer’s HyperPolling wireless dongle (sold separately though), but no Chroma dock integration here, just pure function over form.
6. RGB and Aesthetics
- Basilisk V3 Pro: Lights up the room with full Razer Chroma RGB support, including underglow and scroll lighting.
- Viper V3 Pro: The aesthetic is very stealth, with zero RGB.
7. Price and Value
- Basilisk V3 Pro: Priced at US$159.99.
- Viper V3 Pro: Slightly more affordable at US$136.99, especially considering its pro-FPS focus.

Conclusion
The Razer Basilisk V3 Pro and Razer Viper V3 Pro are both solid mice, but that’s expected of Razer. Whichever you decide to take, you’re still getting one of the best out there. But, what is it to you? Do you want precision-focused speed or feature-packed control?
The Razer Viper V3 Pro is built for esports pros and FPS fanatics who need a featherweight mouse with zero distractions. It’s lean, mean, and all about performance.
But the Razer Basilisk V3 Pro brings a little bit of everything to the table: custom buttons, RGB flair, ergonomic comfort, and a hyper-responsive scroll wheel. It’s the ultimate choice if you want one mouse with hyper features.
