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

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.
