ATMega328p (Aka: Arduino Uno) is 24MHz, 2kB of SRAM, and 32kB of Flash (ROM / program space). Arduino Uno is more powerful than the NASA Apollo Guidance Computer that guided the space program to land on the moon (43 kHz). With an addon SPI-SRAM chip, you could have more SRAM than the guidance computer too.
