Chrome Hits 61 Speedometer Score on M5 MacBook Pro, Beating Safari in 2 Benchmarks

3 articles · Updated · MacRumors · Jun 5

Summary

  • Google said Chrome set new browser speed records on an M5 MacBook Pro, scoring 61 on Speedometer 3.1 and 469 on JetStream 3.
  • Those results were up 5% from last year on Speedometer and 10% since early 2026 on JetStream 3, giving Chrome what Google called a dual lead over all other Mac browsers, including Safari.
  • Google tied the gains to engine changes that cut unnecessary JavaScript execution, inlined asynchronous operations and added fast paths for common tasks.
  • The company also said WebAssembly and Blink rendering optimizations helped lift benchmark performance, which it argues should translate into faster everyday browsing.
