Solve : what does cpu "nm" mean??

1.	Solve : what does cpu "nm" mean??
Answer» When COMPARING two chips for a potential upgrade)( the pentium d 820 and the d945 ) I see that the only difference in the specs that could possibly affect compatability is LABELED lithography -- the 820 is 90 nm and the 945 is 65 nm. What does this mean, and would it affect whether or not a particular mobo could handle the faster chip? Thanks for any help!The nm is the process the CPU was created on - generally the lower the newer and the less power it will DRAW for a given speed, and thus should also run cooler. This is not comparable across different CPUs however, just like clock speed. What board do you have?Nanometers... The smaller the # the more TRANSISTORS can be crammed onto the chip...
