The Razer BlackWidow V4 Pro is a mechanical gaming keyboard that continues Razer's BlackWidow lineup and is available with either linear or clicky switches. New features introduced with this entry include sound-dampening foam layers, pre-lubed stabilizers, dedicated macro keys on the left side of the keyboard, and a maximum polling rate of 8000Hz. This keyboard also has a rotary knob and a multi-function roller, both of which you can use to adjust volume, scroll through media, or adjust backlighting brightness and other keyboard settings. You can change the behavior of these controls and a wide range of other settings using the customization software.
Our Verdict
The Razer BlackWidow V4 Pro is an excellent gaming keyboard. It has exceptionally low latency, and the clicky Green switches have very low pre-travel and feel relatively light to press, making them very responsive. Unfortunately, these switches are somewhat inconsistent in how they sound and feel, but there's also a linear Yellow switch type available that we don't expect to exhibit this inconsistency. That said, the build quality is good overall. There are also many extra features, including a USB passthrough and eight dedicated macro keys that you can customize directly on the keyboard or within the customization software.
- Exceptionally low latency.
- Has two adjustable incline settings and an included wrist rest.
- 8000Hz maximum polling rate.
- All keys are macro programmable, and there are additional dedicated macro keys on the left side.
- Full RGB backlighting.
- Clicky Green switches are satisfying overall but individual switches sound and feel inconsistent.
- While better than average, the ABS keycaps aren't as high quality as PBT keycaps.
The Razer BlackWidow V4 Pro is a good keyboard for office work, though it isn't designed specifically for this use. It feels well-built and has two incline settings and an included wrist rest for added comfort. The clicky Green switches are satisfying to type on, but they sound and feel somewhat inconsistent and are too loud for most open offices. That said, this keyboard is also available with linear Yellow switches instead, which are much quieter.

The Razer BlackWidow V4 Pro isn't suitable for use with mobile devices or tablets.
The Razer BlackWidow V4 Pro is a good keyboard for programming. It feels well-built and has adjustable incline settings and a detachable wrist rest. You can program macros to any key, and there are eight dedicated macro buttons on the left side of the keyboard that you can program directly on the board or using the customization software. It also has full RGB backlighting with shine-through keycaps that are easy to see in darker rooms. The clicky Green switches are fairly light to press and provide satisfying clicky feedback. Unfortunately, some of these switches sound and feel somewhat inconsistent. This keyboard is also available with linear Yellow switches, which we don't expect to exhibit this same inconsistency.

The Razer BlackWidow V4 Pro is a sub-par keyboard for an entertainment or home theater PC setup because it's a wired-only keyboard, meaning you'll need to sit close to your PC to use it. It's also large and difficult to move around, even with its wrist rest removed. It feels well-built, has dedicated media keys, and has full RGB backlighting with shine-through keycaps, making the legends easy to see in darkened rooms.
- Full RGB backlighting.
- Clicky Green switches are satisfying overall but individual switches sound and feel inconsistent.
- While better than average, the ABS keycaps aren't as high quality as PBT keycaps.
- Wired-only.
- Large, even compared to other full-size options.
The Razer BlackWidow V4 Pro has excellent overall performance with outstanding single-key and excellent multi-key latency. It's also one of few keyboards with an 8000Hz effective polling rate, delivering extremely consistent latency performance. The unit we bought and tested uses clicky Razer Green mechanical switches, which have very low-pre-travel. However, the biggest downside is that these switches require significant travel time on release, which is an issue if you play games requiring fast, repeated inputs. See the Multi-Key Latency section below for more details.

Popular Keyboard Comparisons
The Razer BlackWidow V4 Pro continues Razer's popular BlackWidow lineup. As a departure from Razer's recent naming formula, this product is a wired-only model, while most other Razer products that carry the 'Pro' designation are wireless models. The standout features of this new entry are a handful of dedicated macro keys on the left side of the board and an 8000Hz maximum polling rate, which means it sends information to your computer eight times more often than most gaming keyboards with a standard polling rate of 1000Hz, producing exceptionally low latency. The build quality is similar to other flagship gaming keyboards from major brands like Corsair and Logitech. However, it uses lower-quality ABS keycaps, which are becoming less common on gaming keyboards at this price point. Additionally, the clicky green switches on the unit we bought and tested feel satisfying, but there's a noticeable inconsistency between individual switches, which is also an issue with several other models in this series, including the Razer BlackWidow V3 Pro and Razer BlackWidow V3 Mini HyperSpeed.

The Razer DeathStalker V2 Pro and the Razer BlackWidow V4 Pro are full-size mechanical gaming keyboards. The DeathStalker V2 Pro is a wireless model with a low-profile design. It's available with linear Red or clicky Purple Razer low-profile optical switch types. On the other hand, the BlackWidow V4 Pro is a wired-only model with somewhat better gaming performance and a higher maximum polling rate of 8000Hz. It's available with liner Yellow or clicky Green Razer switches.
The Razer Huntsman V2 and the Razer BlackWidow V4 Pro are full-size wired gaming keyboards with very similar gaming performance. The Huntsman V2 has higher-quality PBT keycaps and is available with either linear or clicky Razer Optical switches. On the other hand, the BlackWidow V4 has additional dedicated macro keys, a higher maximum polling rate of 8000hz, and a multi-function roller bar which the Huntsman lacks. It's available with either clicky Razer Green or linear Razer Yellow switches.
The Razer Huntsman V3 Pro 8KHz and the Razer BlackWidow V4 Pro are high-end gaming keyboards. Both keyboards deliver outstanding latency performance, but the Huntsman does have the edge. It uses Razer's optical analog switches, which offer useful features like adjustable actuation that enable Rapid Trigger and other advanced features, while the BlackWidow uses regular mechanical switches. This is the main difference between those two otherwise very comparable keyboards.
The Razer BlackWidow V4 Pro and the Razer BlackWidow V4 are wired mechanical keyboards in the same product lineup. The difference between these boards is that the BlackWidow V4 Pro has several additional features, including one more layer of sound-dampening foam inside the case, additional RGB lighting zones in the wrist rest, additional macro buttons on the left edge of the keyboard, and a programmable knob that Razer calls a 'command dial.' That said, the standard BlackWidow V4 has one additional macro key in place of the command dial, but it lacks the three additional macro buttons on the left edge of the case.
