34 facts in comparison
Razer Viper V4 Pro vs Razer Viper V3 Pro
Two generations of the same competitive mouse, and the honest question is whether the newer sensor changes anything a hand can feel. Both track faster than a human arm can move; both poll at rates no game needs; both are ambidextrous, wireless-only shapes built to be as light as Razer can make them.
The V4 Pro's changes are all in the direction of less and faster. It is five grams lighter, its Focus Pro sensor is rated for 50,000 dpi and 930 inches per second against the V3's 35,000 and 750, its acceleration rating is higher, its optical switches are a generation newer, and its battery life nearly doubles. It also drops to six buttons from eight, and it drops the wired mode entirely - it is a 2.4 GHz mouse that charges over a cable rather than one that also runs over it.
None of the sensor figures will be reached in play. Both mice are already beyond the point where tracking speed limits anyone, and the difference in dpi ceiling is a specification-sheet number. What a player will notice is the weight, the battery, and possibly the switch feel; what a player might miss is the pair of buttons the V4 removes.
The V3 Pro's case is that it is the same shape with a lower price, a wired fallback, and two extra buttons, at a sensor level that was competitive last year and still is.
The V4 Pro is the choice for a competitive player who already uses the Viper shape and wants the lightest, longest-running version of it. The V3 Pro is the choice for anyone who wants the shape and the sensor without paying for the last five grams - or who uses those side buttons.
