The Savu by Roccat uses an Optical sensor from Avago, the ADNS-3090, providing a DPI/CPI range of 400, 800, 1600 or 4000dpi. This results in a tracking speed of 60ips, and a maximum acceleration of 20g. It uses a USB connection with a 1.8m braided cable. It weighs in at 90g without the cable and is approximately 120 x 72 (LxWxH).
