The Snapdragon 810, a common chip on smartphones in the $50 range, averages about three billion floating-point operations per second (GFLOPS) across a range of performance benchmarks.[203] This corresponds to around 60 million computations per second per dollar. The best available computers in 1965 achieved about 1.8 computations per second per dollar, and in 1985 they were up to about 220.[204] At those efficiencies, it would have taken almost $1.7 billion (in 2023 dollars) to match the Snapdragon in 1965 and $13.6 million in 1980.
