The Razer Viper 8KHz is a lightweight, true ambidextrous mouse thanks to the two buttons on either side. It looks physically identical to the Razer Viper, but with a slightly thicker cable and smoother-gliding feet. It has an incredibly low click latency, a low lift-off distance, and a wide CPI range. Like the Razer Viper, it's suitable for most hand sizes when using a fingertip grip, but people with small hands may struggle to reach the L/R clicks and scroll wheel. What sets it apart from other gaming mice is its 8000Hz maximum polling rate, which should provide a much more fluid cursor movement; however, we don't currently test this.
Our Verdict
The Razer Viper 8KHz is decent for office use. While it doesn't have an ergonomic shape like some dedicated office mice, it should still feel very comfortable for most hand sizes using a claw or fingertip grip, and for small and medium hands using a palm grip. It feels very well-built, and it has many programmable buttons; unfortunately, its customization software isn't available on macOS. Also, it isn't wireless, and some people might find the cable cumbersome.

The Razer Viper 8KHz is very good for MMO gaming. While it doesn't have nearly as many side buttons as dedicated MMO mice, it does have two side buttons on either side, which is more than many other gaming mice. On the bright side, it has a very low click latency, a wide and customizable CPI range, and a low lift-off distance. Also, it has an 8000Hz maximum polling rate, so cursor movements should feel more fluid, but we don't currently test this. It feels very well-built and very comfortable, but people with larger hands may struggle with a palm grip.

Test Results
The Razer Viper 8KHz looks identical to the Razer Viper, but it has a thicker cable. Otherwise, it has the same ambidextrous, matte black design with two buttons on each side. It also has an RGB-lit logo on its back.
Despite not having a honeycomb design, the Razer Viper 8KHz is very light. It's only marginally heavier than the regular Razer Viper.
It feels very well-built, similar to the Razer Viper. While there are no rattling or squeaky parts, our unit's plastic body exhibits some flex.
The Razer Viper 8KHz has a true ambidextrous design with two buttons on each side, exactly like the Razer Viper and the Razer Viper Ultimate. It has nice textured grips on both sides, and all of its buttons feel well-placed. Due to its short body, it's best suited for a claw or fingertip grip for most hand sizes, although people with small or medium hands may also feel comfortable with a palm grip.
Due to its short and low-profile design, it isn't suitable for large or extra-large hands with a palm grip. However, people with small or medium hands should feel comfortable.
It's suitable for most hand sizes when used with a claw grip, but it may feel too small for people with extra-large hands.
It's suitable for most hand sizes when used with a fingertip grip, but people with small hands may struggle to reach the scroll wheel.
The Razer Speedflex cable on the Razer Viper 8KHz is basically identical to other cables in the Viper lineup, but it's slightly thicker. It's fairly flexible, but it retains kinks from the packaging.
The Razer Viper 8KHz's virgin grade PTFE feet glide very smoothly on both mouse pads and directly on desks. They're much better than the ones on the regular Razer Viper.
The Razer Viper 8KHz has a very wide CPI range that can be adjusted fairly precisely in increments of 50. The set CPI is consistent, but it tends to overshoot a bit more when you move slower than when you move fast; however, this shouldn't be noticeable to most people. It has a low lift-off distance, so the sensor shouldn't track your movements when you reposition your mouse.
The biggest difference it has with the other Razer mice is the polling rate: along with the usual 125Hz, 500Hz, and 1000Hz, it can also be set to 2000Hz, 4000Hz, or 8000Hz. When set to a higher polling rate, the cursor movements should feel smoother and more fluid, but we don't currently test this.
The Razer Viper 8KHz uses optical switches for the main click buttons. Every button can be reprogrammed, including all four side buttons, the CPI switch on the underside of the mouse, and the up/down scrolls. Also, you can set a HyperShift button that gives you a second layer of programmable inputs for as long as you hold it. While you can reprogram the left click, you need to reassign the left click action to another button first.
The scroll wheel on the Razer Viper 8KHz is a standard incremented wheel with very defined notches. However, it's a bit stiff, so you may accidentally middle-click because of the extra pressure you use to scroll.
The clicks are quiet and shouldn't bother people around you, even in a noise-sensitive environment.
The Razer Viper 8KHz's click latency is incredibly low and should feel very responsive.
The Razer Synapse 3 software is great and very user-friendly. You can easily customize most aspects, including the buttons, RGB lighting, set CPI, and polling rate. You can save your settings on the mouse's onboard memory, so all your customizations will remain when switching to another computer. Unfortunately, the software isn't available on macOS.
While it's fully compatible with Windows, the software isn't available on macOS, so you can't remap the mouse's controls or customize the lighting to anything other than the default settings.
Differences Between Sizes And Variants
The Razer Viper 8KHz has no variants, and it's only available in black. See the label of our unit here.
Compared To Other Mice
While it has the same ambidextrous design as other mice in the Viper lineup, with buttons on both sides, the biggest difference with the Razer Viper 8KHz is its maximum polling rate of 8000Hz. It should provide even smoother cursor movements and less micro stutter than mice with 1000Hz polling rates; however, we currently don't test this. Otherwise, it has an incredibly low click latency, a very wide and adjustable CPI range, and a consistent sensor. For other options, see our recommendations for the best gaming mice, the best wired mice, and if you'd prefer a wireless design, check out the best wireless gaming mice.
The Razer Viper 8KHz and the Razer DeathAdder V2 are excellent wired FPS gaming mice that perform similarly. The 8KHz is an ambidextrous mouse with two buttons on each side, and it has an 8000Hz polling rate, which should provide more fluid cursor movements; however, we currently don't test this. On the other hand, the DeathAdder V2 has a higher back with a slanted, right-handed design, so it's more suitable for a palm grip no matter your hand size.
The Razer Viper 8KHz performs better than the Razer Viper Mini for most uses, though both mice look similar. The 8KHz is slightly bigger and feels a little more comfortable, especially if you have medium or large hands. Performance-wise, it has a much wider CPI range that you can adjust more precisely and with very little variation. It also has a lower lift-off distance and an outstanding maximum polling rate of 8000Hz, which results in smoother movement, though we don't test for this. Lastly, the 8KHz features two side buttons on each side, while the Mini only has two buttons on its left side. That said, the Mini is smaller and weighs a bit less, so it may be a better choice for people with smaller hands, especially those using a fingertip grip.
The Razer Viper 8KHz and the Razer Viper Ultimate have the same ambidextrous body, but the Viper Ultimate is wireless, while the 8KHz is wired-only. Aside from some slight variances, like the 8KHz's slightly lower click latency and more consistent sensor, the biggest difference is the max polling rate. While the Ultimate caps out at 1000Hz, the 8KHz can be set as high as 8000Hz, which results in more fluid cursor movements, though we don't currently test this.
The Razer Viper 8KHz and the Logitech G PRO X SUPERLIGHT are both excellent FPS gaming mice. If you're a fan of ultra-light mice, the Logitech is worth considering because it's one of the lightest wireless mice we've ever tested. Also, it can be used both wired and wireless, and it's fully compatible with macOS. On the other hand, the Razer has RGB lighting, two programmable side buttons on each side, and a lower click latency. Also, it has an 8000Hz polling rate, which should provide more fluid cursor movements, though we don't currently test this.
The Razer Viper and the Razer Viper 8KHz have the same shape and design, but the 8KHz has smoother-gliding feet and a thicker cable. It also has a lower click latency and has onboard memory. The biggest difference between the two is the 8000Hz polling rate on the 8KHz, which means its cursor movements should feel more fluid, though we don't currently test this. If you want a future-proof mouse with onboard memory, the 8KHz is an excellent choice.
The Razer Viper 8KHz and the Razer Basilisk V2 are both excellent FPS gaming mice. The V2 has a thumb rest and a sniper button on its left side, and overall has more programmable inputs, but its click latency is slightly higher. On the other hand, you can set the 8KHz to a maximum of 8000Hz, which provides more fluid cursor movements, though we don't currently test this. The 8KHz also has two buttons on both of its sides.
The Razer Viper 8KHz is a better gaming mouse than the Logitech G Pro Wireless, but the Logitech is more versatile. The Logitech can be used wired or wirelessly, and it's fully compatible with both Windows and macOS. It's slightly heavier than the Razer, but it's still lightweight, and you can easily bring it with you on the go. It has a nearly universal shape that should fit most hand sizes and grip types. On the other hand, the Razer is a bit lighter, and its shape is better suited for a claw grip or a fingertip grip if you have medium to extra-large hands. It has a much better cable and feet that glide more smoothly. While its CPI range isn't as wide as the Logitech, its maximum polling rate is impressively high at 8000Hz. This should results in smoother movements, though we don't test for this at the moment.
The Razer Viper 8KHz and the Corsair SABRE PRO are wired mice with similar performance, including maximum polling rates of 8000Hz. The Corsair has a right-handed shape that's well-suited for palm grip, regardless of hand size, but those with small and medium-sized hands may not be able to reach all buttons using a claw or fingertip grip. It has a narrower CPI range, but you can set the CPI by increments of one using the companion software compatible with Windows and macOS. On the other hand, the Razer has an ambidextrous shape that's well-suited for smaller hands using a palm or claw grip and larger hands using a fingertip grip. Its CPI has a wider range but can only be set by increments of 50. It also has two additional side buttons on the right side, RGB lighting, and better mouse feet, although its software is only compatible with Windows.
The Logitech M100 is a sub-par, budget office mouse, while the Razer Viper 8KHz is an excellent FPS gaming mouse. The Razer feels sturdier, has four side buttons, a more flexible cable, and better-gliding mouse feet. It also has an adjustable CPI, a much higher polling rate of 8000Hz, a significantly lower click latency, and software for customization. The Razer is best-suited for a palm or claw grip for smaller hands or a fingertip grip for larger hands. Comparatively, the Logitech is lighter and well-suited for all grip types and nearly all hand sizes.
The Razer Viper 8KHz is a better wired gaming mouse than the Redragon M601 RGB Centrophorus. The Razer is lighter, it has a cable that's more flexible, and it has mouse feet that glide more smoothly. It also has a much wider CPI range, a CPI you can adjust precisely by increments of 50, a much lower click latency, a lower lift-off distance, and a higher maximum polling rate of 8000Hz. It also has two additional side buttons on the right side, and you can set a HyperShift button to enable a secondary layer of controls. On the other hand, the Redragon has a set of added weights for adjusting the weight distribution, which the Razer lacks.
The Razer Viper 8KHz performs better overall than the Nixeus REVEL Fit. The Razer has a lighter weight, a better build quality, a more flexible cable, and much smoother–gliding feet. Performance-wise, it has a wider CPI range, a more precisely adjustable CPI, a much lower lift-off distance, and significantly lower click latency. It has a maximum polling rate of 8000Hz that should make the cursor movements feel smoother and more fluid than the Nixeus' 1000Hz polling rate, but we don't currently test this.
