How Computer Speed Has Evolved: From Room-Sized Behemoths to Nanosecond Wizards
Before computers transformed every aspect of daily life, their speeds—and even their sizes—were staggering. Consider ENIAC, the earliest electronic general-purpose computer built in 1945: it weighed 30 tons and could perform about 5,000 operations per second. Today’s fastest computers can execute quadrillions of instructions in a heartbeat, shrinking time frames from seconds to nanoseconds. The story of computer speed is one of relentless innovation, driven by global competition, scientific ambition, and the dream of simulating reality itself.
The journey began with mechanical devices and vacuum tubes, moved quickly into transistors, and exploded in the age of microprocessors. Companies, universities, and governments have poured billions into pushing boundaries, knowing that the fastest computers determine breakthroughs in everything from weather forecasting to medicine. As you’ll see, the pace of progress is mind-boggling—and the implications are world-changing.
