Google Chrome has achieved the highest scores ever recorded on the Speedometer 3.1 and JetStream 3 browser benchmarks, tested on an M5 MacBook Pro. Chrome scored 61 on Speedometer, a 5% improvement over last year, and 469 on JetStream 3, a 10% increase since the start of 2026. Google claims this is a dual record across all Mac browsers, beating Safari and every competitor.
Why Chrome outperforms Safari on Apple Silicon
The performance leap comes from a deep rework of Chrome's JavaScript engine. Google eliminated unnecessary execution steps and inlined asynchronous operations, creating fast paths for common operations. These optimizations translate into real-world speed gains for everyday tasks like page loading, tab switching, and web app performance. WebAssembly workloads and the Blink rendering engine also received significant improvements, detailed on the Chromium blog.

What this means for Apple users
Benchmarked on an M5 MacBook Pro running macOS 26.0.1, Chrome proves it can fully leverage Apple's latest chips. As Apple gears up for WWDC 2026 and its redesigned AI-powered Siri, browser speed remains a key battleground. Users prioritizing performance may now favor Chrome over Safari, potentially pushing Apple to enhance its own browser. This achievement comes amid heightened cybersecurity concerns, with Google, FBI, and NSA recently warning about physical ransomware and spy AI threats.
