About this deal

But additionally, the mouse is literally ambidextrous (identical on both sides) – so it’s the perfect product for a left-handed mouse user! I just got mine after having a Logitech G502 (non-ambidextrous mouse) for like….7 years…. And as a right-handed mouse user, I was pretty worried about the ambidextrous design. But after just two days of use, I can confirm that this mouse feels amazing! The only issue is that the buttons on your non-thumb side of the mouse are a bit difficult to reach – but that 8000hz polling rate makes it feel absolutely amazing so long as you computer is beefy enough to push your games at a high refresh rate. But anyway, being that you currently have a mouse that is extremely similar to my G502, you’d probably get adjusted to the Viper in a few days – just like I did. The Viper 8K Hz is specced for up to 20,000 CPI, a max velocity of 650 inches per second (IPS) and max acceleration of 50g. For comparison, we brought in two 1,000 Hz mice: If you do use Synapse, you can store an limited number of profiles, including with RGB settings, usable with the software open, and every profile will be able to launch automatically with specific games or other apps. On to the mouse, then. I have never extensively tested a regular Viper but I did review the Viper Ultimateand Viper Miniso I have some experience with the product line. What immediately caught my attention when I first grabbed the 8KHz is how much better the buttons feel. I had no problems with the first iteration of Razer’s optical mouse switches (at least not on the units that I got for review) but it couldn’t be denied that they felt a fair bit less crispy than actual mechanical switches, and it feels as if Razer has really been working on that aspect.

We've converted this review to Test Bench 1.2. This update simplifies our Weight test and expands on our CPI test from Test Bench 1.1, resulting in changes to test results in both sections. For more details, you can see our complete changelog here. Polling rate isn’t the only thing boosted on the Viper 8K Hz. Even if you ignore the high polling rate, this is a high-specced rat, thanks to Razer’s homegrown Focus+ optical sensor. Although in introducing this mouse Razer is saying demonstratively and literally that it thinks a high polling rate enhances the gaming experience more than high CPI, the Viper 8K Hz still goes up to 20,000 CPI. The sensor is also specced to handle velocities of up to 650 IPS and 50g of acceleration. That’s an upgrade from the original Viper, which uses the Razer 5G optical sensor (16,000 CPI / 450 IPS / 50g) but matches the pricier wireless Viper Ultimate’s specs. But unless you game at the highest CPI (most don’t) or move your mouse with super aggression, you probably would’ve been fine with the 5G. Everyone can use it, too. Much like the older models, this Viper is cleverly put together so that the unneeded side buttons won't be accidentally hit during play (the same is true of having the DPI button on the underside of the mouse, which is a decision I'm not a fan of but I understand the logic behind it). Razer Viper 8K – Design and FeaturesThe Razer Viper 8K feels like an old friend — and it should. There are virtually no differences between the original Razer Viper and the Viper 8K I’m reviewing today. That’s a very good thing, as the original Razer Viper is one of my favorite mice ever. It’s also good because the original Viper is being phased out and replaced with this upgraded version at no extra cost. It’s a medium-sized ultralight mouse (71 grams) that works well whether you’re a palm, claw, or fingertip gripped gamer. That versatility even extends to being a righty or lefty thanks to its 8-button ambidextrous design.

Customer reviews

The Razer Viper (the wired version) has always been the neglected sibling in the family. Yes, it came first, but the Ultimate edition is much more impressive on a technical level, and the Mini version was something that a lotof people in the community had been asking for, so the regular wired version has been somewhat forgotten over time. But no more of that. While the community was busy fawning over its siblings, the Viper quietly went to work, and a couple of motivational montages later it emerged as the Viper 8KHz. As great as this mouse is there are a couple trade offs and things I didnt know. these are not in number of importance. The reason for this is because of CPU use, it’s possible that 8K could actually lower your in-game FPS if you’re running an processor or graphics card.

Let me first say that this 8KHz isn’t some sort of ‘advanced edition’ of the regular Viper. It costs the same amount of money (at least at MSRP: of course local prices can vary) and is meant to just outright replace the regular Viper. To me that’s the right decision: it ensures that more people will get their hands on this new technology and it’s also a way for Razer to say ‘we think that this is the future.’ For wired mice, at least. Slapping this tech in a wireless mouse just isn’t feasible right now according to some Razer representatives, so I wouldn’t hold my breath waiting for a Viper Ultimate 8KHz anytime soon in case you were wondering about that. That emphasis on peak performance is mirrored by the grips on each side. Made up of tiny rubber hexagons, they stop the mouse from flying out of your grip during a particularly intense match. On much the same note, the DPI button has been relegated to the device's underside in an attempt to avoid accidental presses.The 144 Hz requirement is more attainable, but Razer claims that the higher the refresh rate, the greater the benefits. This is a future-proofing mouse, and it’s best mate currently is, really, a 360 Hz monitor, which we’ve found to show noticeable improvements in speed and response compared to 240 Hz monitors. I didn’t have one on hand though, so for my testing I used a Razer Blade 15 Advanced Model, one of the best gaming laptops. Of course, when it comes to input lag there are other factors at work besides the mouse's individual latency. The overall amount of time it takes for my mouse input to appear on screen not only depends on the mouse, but also how long my CPU and GPU take to process it, as well as the screen. I have decent specs here, but the lowest latency results possible would require something like a desktop RTX 3090, along with a 360 Hz monitor.

Then I used a polling rate of 4kHz for some days. CSGO was stable and my FPS were good. Even the polling rate was stable: As always I’d like to conclude this section with a disclaimer: I don’t know you, so I don’t know your preferences. You might have smaller hands and love large mice, or you might prefer super flat mice even with a palm grip. Always take these ‘grip and size recommendation’ portions by us reviewers with a grain of salt, as everyone is different. Buttons and Scroll Wheel

For transparency this is my first razer mouse, and only my 3rd mouse. fist was a cheap havit mouse that came with a bundle. second was a steelseries 600. Honestly I assumed I'd get this mouse and be underwhelmed. VSyncTester’s HTML/JavaScript mouse input performance benchmark looks at mouse latency. Again, this test is subject to how consistently I can move each mouse, but the Viper 8K Hz managed the best score, usually in the 3.30ms range. The DeathAdder V2 Mini and Burst Pro were both typically in the 3.40ms area, not far behind. After a restart to apply this change, I did a new the Polling Rate test with the mouse configured in 8kHz, the results are perfect now:

Powered by Razer's own 'Hyperpolling Technology', the Viper 8K aims to lower latency well below what we're used to. In fact, it offers a polling rate of 8,000Hz - significantly beyond the industry average of 1,000Hz. To translate, this removes cursor stutter on displays with a higher refresh rate by telling your PC or laptop where the cursor is more frequently. In fact, Razer suggests that the 8K reduces input delay from 1ms to 1/8th of a millisecond. The gap between your input and movement on-screen becomes much, much smaller as a result. We've added a link to the newly-reviewed HyperX Pulsefire Haste 2 in the Weight section of this review. The 8k polling rate. this provides an extremely smooth mouse movement. this may be different from person to person. maybe mouse pads make a huge difference I have a relatively cheap one atm. One issue I've run into is Apex legends WILL NOT run a polling rate over 2000 on a 144 hz monitor. or at least not on mine. rainbow six siege I can crank to 8k and no issues. so maybe its game/display/system dependent I dont have a way to test it.

For a full explanation on my thoughts on 8KHz you’ll need to go the ‘performance and sensor’ section, but in short I’ll say: there are more important factors to a gaming mouse than the polling rate. Don’t get this one if you know you will dislike the shape, thinking that the 8KHz polling rate will catapult your aiming skills into the stratosphere. It won’t do that. But if you’re already used to the shape and you’ve got the system to match it might make you a bit more consistent. Some examples are the ‘Raw Input Buffer’ in Valorant and ‘High Precision Mouse Input’ in Overwatch. As such, the Viper 8K Hz is decently easy to move around for its weight, and the 100% PTFE feet on the bottom help. They provide a noticeable amount of extra glide, making the mouse as easy to control as the lighter (2.40 ounces) Roccat Burst Pro, but not more effortless to control than the super small and lightweight (2.24 ounces) Razer DeathAdder V2 Mini.
