Razer Viper 8K Hz Review

In this guide

Editorial rating: 4.00 / 5 ⭐️’s

Quick take

The Razer Viper 8K Hz is an excellent gaming mouse that is incredibly fast and accurate, making it a good fit for fast-paced titles where responsiveness matters. Its insanely high polling rate explains some of the impressive latency performance, though it may not be noticeable for some gamers. We’d expect similar performing and equal build quality mice to cost double the price. But Razer bucks that trend here and keeps the price low because it’s a wired gaming mouse. If that’s not an issue for you, then this may be the best gaming mouse for you with its robust functionality, great build quality, and lightning-fast performance. It can also be used right or left-handed since it’s symmetrical with buttons on both sides.

Razer Viper 8KHz

  • Great click latency
  • High DPI sensor
  • Super high polling rate
  • Ambidextrous design
  • Not a fit for all grip styles
Razer Viper 8KHz
  • Weight: 71 grams
  • Sensor: Razer Focus+ 20k DPI
  • Polling rate: 8000 Hz
  • Buttons: 8
  • Battery life: N/A
  • Connectivity: Wired
  • Compatibility: Windows, macOS (No software compatibility)


If you want a wireless gaming mouse: The Razer Viper V2 Pro has the exact same shape but is wireless and has upgraded internals, such as a higher DPI sensor and Razer’s newest generation of optical switches. It is also much lighter. The Razer Viper V2 Pro doesn’t include buttons on both sides, so it only fits if you’re right-handed.

If you have small hands or want a lighter mouse: The Razer Viper Mini has the same form factor as the Razer Viper 8K Hz but in a smaller size. The weight is reduced meaningfully as a result.

If you want an ergonomic mouse: The Razer DeathAdder V3 Pro is Razer’s flagship ergonomic gaming mouse. Importantly, both models have high latency performance and precise, high DPI sensors. But the Deathadder V3 Pro has an accentuated ergonomic shape that may be more suitable for certain grip styles and larger hands. The Deathadder V3 Pro is considerably more expensive as well.

The Razer Viper 8K Hz weighs in at just 71 grams. It’s not the lightest gaming mouse out there, but it is still light compared to gaming mice in general. In fact, many gaming mice in the same category can weigh up to 90 to 100 grams. The Razer Viper 8K Hz’s weight is achieved without a honeycomb casing with holes or open bottom chassis.

The Razer Viper 8K Hz includes the Razer Focus+ 26,000 DPI sensor. This optical sensor is fast and precise with such a high DPI.

Razer has a deep lineup of branded sensors it uses in its gaming mice, and the company offers several Focus+-branded sensors through its partnership with PixArt. The main difference between the two Focus+ sensors is the DPI – the sensor comes in a 20,000 or 26,000 DPI variant.

The sensor also enables several unique features that are great on paper but may not be valuable for most gamers. The Razer Focus+ sensor offers what Razer brands as Smart Tracking and Asymmetric Cut-off.

Smart Tracking automatically calibrates the sensor when moving across different surfaces to retain consistent accuracy and lift-off distance.

Asymmetric Cut-off allows you to customize the landing distance at which the Razer Viper 8K Hz will begin tracking again. This feature improves precision when lifting your mouse and setting it back down again, such as when flicking headshots.

Polling rate

The namesake feature of the Razer Viper 8K Hz is its insanely high 8000 Hz polling rate. This feature produces some of the best latency performance we’ve come across. Other top-tier gaming mice cap out at a 1000 Hz polling rate, which is still incredibly high.

The high polling rate explains why the Razer Viper 8K Hz is one of the fastest gaming mice available. In short, this gaming mouse reports actions back to your computer 8,000 times per second. More frequent reporting reduces latency and can create a smoother cursor movement experience on the best gaming monitors with high refresh rates, giving you a minor edge in fast-paced games, such as battle royale titles where fast and accurate aiming is critical.

To be clear, most casual gamers are unlikely to notice the performance edge between a mouse with a 1000 Hz polling rate and one with an 8000 Hz polling rate. We’re talking fractions of a millisecond in terms of latency performance. But if you want to get a competitive latency edge, however minor it may be, then the Razer Viper 8K Hz delivers.

Switches performance and sound

The Razer Viper 8K Hz includes Razer’s optical gen-2 switches, which are rated for at least 70 million clicks, and are among the highest durability available. These are fast since they’re optical switches, a common feature among the best FPS gaming mice. Razer’s software and firmware tuning further reduce click latency. The result is some of the lowest click latency we’ve come across in 2023.

Razer does offer gen-3 switches in some of its mice, such as the Razer Viper V2 Pro and the Razer DeathAdder V3 Pro. The main difference between the two switches is their durability. The gen-3 switches are rated for 90 million clicks. Otherwise, the two Razer-branded switches feel the same. Both have a crisp feel with somewhat muted clicking sounds.


Razer Viper 8K Hz Feet

The Razer Viper 8K Hz slides effortlessly across mousepads and desk surfaces with its array of three Virgin-Grade PTFE feet. The gliding is so sensitive that you can move the mouse more than expected when inadvertently bumping it.

There’s one large foot across the back of the mouse, a narrower foot spanning the width of the front of the mouse, and a small foot surrounding the sensor. These well-placed feet, along with the lightweight, are what create such a snappy gliding experience. While you can buy aftermarket feet for the Razer Viper 8K Hz, we don’t necessarily see the need to do so, except if the feet are worn out.

This is one of the few gaming mice that works for right- and left-handed users. There are eight buttons on the Razer Viper 8K Hz, including two on both the right and left sides.

A DPI button on the underside of the mouse can be used to rapidly change DPI settings.

All of the Razer Viper 8K Hz buttons, including the DPI button on the underside, can be reprogrammed in Razer’s Synapse software. You can also enable HyperShift in Synapse, which provides an additional layer of functionality, just like using the Shift key on a keyboard.

Scroll wheel

The scroll wheel has a rubber coating with small protrusions along each step, making it effortless to scroll the wheel. Other lesser gaming mice include slicker-surfaced scroll wheels that can make it hard to precisely control the wheel. The scroll wheel doesn’t offer left/right click functionality or the ability to enable free scrolling.


The Razer Viper 8K Hz uses the popular design language included throughout Razer’s deep Viper lineup. The best way to describe the shape is that it has a slightly lower-than-average height profile and hump under your palm, with somewhat elongated, recessed L/R buttons. The side buttons are also slightly smaller than other gaming mice, though still easy to reach with your thumb.

This mouse also includes a grippy rubberized texture on both the left and right sides that improves handling, particularly for claw grips.

The Razer Viper 8K Hz sides also have a slight inward, recessed curve in the midsection. The curve is not accentuated enough to call this an ergonomic mouse, but it improves the comfort of holding the mouse and your holding power.

Hand size and grip style

The Razer Viper 8K Hz is great for medium-sized and larger hands with its low profile and slightly elongated shape. The Razer Viper Mini is the perfect alternative if you like the Viper design language but have small hands or want a small gaming mouse to reduce weight.

The elongated design is also good for palm grip users who want support under their palm’s length. Mice such as the Logitech G Pro X Superlight or the Glorious Model D may be better if you like a higher profile under your palm for the most support.

The Razer Viper 8K Hz’s grippy side texture and narrowed midsection improve the holding power, which suits a claw-grip style well.

Razer Viper 8K Hz RGB

The Razer Viper 8K Hz is uncharacteristically Razer with its few RGB customization options. Only the logo on the mouse’s backside includes RGB, which can be customized with varying effects. The limited RGB options are to be expected for a gaming mouse that is hyper-focused on performance, which comes at the cost of fewer RGB options.

Memory profiles

You can store onboard the Razer Viper 8K Hz up to five profiles configured in Synapse. This way you can create custom profiles and easily switch between them on the fly.

Synapse software

Razer’s Synapse is one of the most robust and user-friendly mouse software experiences available. You can endlessly customize your Razer Viper 8K Hz’s configuration in Synapse, including the following:

  • Remap your mouse buttons, enable HyperShift for an added layer of customization, and set the mouse for right or left-handed use
  • Adjust the DPI presets in increments of 50 from 100 to 20,000
  • Enable custom X and Y sensitivities
  • Adjust the polling rate from 125, 500, 1000, 2000, 4000, and 8000 Hz presets
  • Customize the RGB effects in Razer’s Chroma software
  • Calibrate the mouse to enable features such as Smart Tracking and Asymmetric Cut-off
  • Set custom configurations to automatically change profiles when opening specific games

Consider that the full suite of customization options is only available on PC. The Synapse software doesn’t work within macOS, though you can use the Razer Viper 8K Hz in macOS. Your custom profiles also work, but you’ll need to hook your mouse up to a PC to remap buttons in the first place.

  • Can the Razer Viper 8K Hz drag click?

    No, the Razer Viper 8K Hz can’t drag click. The L/R button’s matte texture isn’t grippy enough to generate sufficient friction to easily drag click, and the optical switches aren’t don’t work well for drag-clicking.

  • Is the Razer Viper 8K Hz fast?

    Yes, the Razer Viper 8K Hz has some of the lowest click latency we’ve come across. Such fast performance is achieved through a combination of Razer’s fast optical switches, the 8000 Hz polling rate, and Razer’s impressive software and firmware tuning.

  • Does the Razer Viper 8K Hz have a warranty?

    The Razer Viper 8K Hz has a two-year warranty. Valid proof of purchase is required, such as the original receipt or the order number if ordered through Razer’s website.
