Claude Code vs Cursor Benchmarks Speed, Accuracy & Token Efficiency
Numbers-first comparison. How the two tools measure up on software engineering benchmarks, token efficiency, and real-world task performance.
ⓘNote: Direct apples-to-apples benchmarks are difficult. Claude Code uses Claude models; Cursor defaults to GPT-4o or Claude depending on task. Scores reflect best available public data and independent testing.

FAQs
How does Claude Code compare to Cursor on benchmarks?▾
On SWE-bench, Claude Sonnet 4 scores approximately 49% versus approximately 38% for GPT-4o (common in Cursor). Claude Code also has a 5.5x token efficiency advantage. However, Cursor is faster for small, everyday tasks where tab completion creates a massive speed advantage.
What is token efficiency and why does it matter?▾
Token efficiency measures how much useful work an AI produces per token consumed. Claude Code's 5.5x efficiency advantage means you get more code output per dollar spent. Over a month of heavy use, this difference is significant — especially at the Pro plan level.
