What is the clock speed of the GP32?
This is software selectable from many different speeds from ~22MHz up to ~133.5MHz. The slower the selected speed, the longer the battery life that you will experience. However, just because the CPU can be set for very high speeds does not mean that the rest of the system (in particular the SDRAM) can handle this speed as well. Bios v1.5.7 defaults the clock speed to 67.8MHz. FireFly and others have managed to run their GP32 at up to 99MHz, with instruction and data cache on, without noticeable problems. Some people appear to experience problems at this speed.
