I don’t know, but it’s fast enough for my gaming needs. I’m sure one can look up the actual spec on the Internet. In settings you can set up to five different movement speeds, how fast the mouse pointer follows the mouse movement. A switch on the side allows one to cycle through your presets. I’ve got three settings, fast, slower, and slower still (but not too slow). There is also a switch on top to toggle between two battery power consumption levels. I use the high settings in both areas for my gaming needs. I also am able to use this mouse just fine without a mouse pad, which I don’t like to use.
