With some exceptions, all cycles the 6502 do something with yhe memory of 
the computer: reading the instruction, reading or writing data, etc. The 
(older) Intel CPU's and Z80 used much more cycles. Even the NOP-instruction 
of the Z80 used 3 or 4 cycles. Comparing to this AND using pipeline AND how 
the fact that instructions are decoded by hardware and not microcode, you 
can consider the 6502 as a real RISC-processor.  

The 6800 is older but the 6502 got more well known. AFAIk the 6800 also 
only used one cycle.
