ENIAC is commonly thought of as the first modern computer.  Built in 1944, it took up more space than an 18-wheeler tractor trailer, weighed more than 17 Chevrolet Camaros, and consumed 140,000 watts of electricity.  ENIAC could execute up to 5,000 basic arithmetic operations per second.

One of today’s popular microprocessors, the 486, is built on a tiny piece of silicon about the size of a dime.  It weighs less than a packet of Sweet ‘N Low and uses less than two watts of electricity.  It can execute 54 million instructions per second.
