Practice question · Numerical answer
Continuing the same doubling every two years from 1 million transistors at year 0, how many million transistors would a chip hold at year 10?
Hints
- Count how many doublings fit into 10 years.
- Ten years at one doubling every two years is five doublings.
Show the answer
32
Why
Five doublings multiply the count by 32, giving 32 million. Miscounting the doublings is the usual error: it is the number of two-year periods that matters, not the number of years.
