How powerful will computers be in 100 years?
What will the future hold for computers? Assuming microprocessor manufacturers can continue to live up to Moore’s Law, the processing power of our computers should double every two years. That would mean computers 100 years from now would be 1,125,899,906,842,624 times more powerful than the current models. Upgrading older hardware can provide noticeable improvements in the short term, but eventually, your computer will become outdated again. Upgrading a 10-year-old computer might only give you an extra year or two of useful life, whereas investing in a new computer could last you five years or more.
What is the most powerful PC?
El Capitan is now the world’s most powerful supercomputer — and the planet’s third-ever exascale machine — after coming online at the end of 2024. As of June 2025, the United States’ El Capitan is the most powerful supercomputer in the TOP500, reaching 1742 petaFlops (1. Flops) on the LINPACK benchmarks.
