Google today announced that its Chrome browser set new browser speed records on two benchmarking tools, Speedometer 3.1 and JetStream 3. The tests were performed on an M5 MacBook Pro running macOS 26.0.1.
Chrome scored 61 on Speedometer, a five percent improvement since last year. The browser earned a 469 on JetStream 3, a 10 percent improvement since the beginning of the year.
Over the past year, our engineering teams have tackled a series of major projects to elevate our JetStream 3 and Speedometer 3.1 scores. Since just the start of this year, we’ve improved Chrome’s score on JetStream by 10% resulting in a record score of 469. In addition we improved Speedometer by 5% since our last blog post on benchmark performance about a year ago, resulting in a dual record across all browsers of 61. Both results were measured on a MacBook Pro M5 running MacOS 26.0.1. These wins directly translate into a meaningfully faster experience for our users.
Google says it holds a dual record across all browsers, beating every other Mac browser, including Safari.
Google boosted its benchmarking scores by reworking JavaScript handling, skipping unnecessary execution steps and inlining asynchronous operations. Inlining “fast paths” for common operations resulted in speed gains across multiple daily tasks.
Improvements were also implemented for WebAssembly workloads and the Blink rendering engine.
