 Instructions took between 5 and 11 T-states, where each T-state was 2 clock cycles.Register–register loads and ALU operations took 5T (20 μs at 0.5 MHz), register–memory 8T (32 μs), while calls and jumps (when taken) took 11 T-states (44 μs).The 8008 was a little slower in terms of instructions per second (36,000 to 80,000 at 0.8 MHz) than the 4-bit Intel 4004 and Intel 4040.
