This week I learned

Week of August 25, 2025: Amdahl's law

Amdahl’s Law demonstrates the theoretical maximum speedup of an overall system and the concept of diminishing returns. If exactly 50% of the work can be parallelized, the best possible speedup is 2 times. If 95% of the work can be parallelized, the best possible speedup is 20 times. According to the law, even with an infinite number of processors, the speedup is constrained by the unparallelizable portion.
