The CPU used in the WonderSwan was the NEC V30MZ, which is a microprocessor based on the NEC V30 architecture. The NEC V30MZ CPU in the WonderSwan handheld console ran at a clock speed of approximately 3.072 MHz. The NEC V30 is an extended version of the Intel 8086 microprocessor, and it offered improved performance and compatibility.
