EC2 Instance Family Performance Ranking

Families are ranked by PassMark single-thread score, measured by RunsOn's open benchmark harness. Multi-core throughput is not ranked. A family's score is the median of runs-on.com's PassMark single-thread figures for its benchmarked instance types (ec2-cpu.json), or of its benchmark runs over the last 180 days. A family without benchmarks of its own takes the score of a family with the same processor: its score is estimated. A family within 3% of the fastest family of a rank shares that rank, and a rank is one plus the number of families in faster ranks. The x86_64 and arm64 views rank their families among themselves. Only families priced in the last 15 days are listed.
