After the release of the M1 version of Chrome, Ars Technica used Speedometer 2.0, JetStream2 and Motion Mark 1.1 to conduct a series of benchmark tests. In all cases, M1 Chrome is much faster than the x86 version.
In the Speedometer 2.0 test, the M1 Chrome score was 210, while the standard Chrome score was 116. In the Jetstream 2 test, the M1 Chrome score was 156.9 and the standard Chrome score was 93.1. In the Motion Mark 1.1 test, M1 Chrome scored 726.4, while the standard Chrome score was 435.7.
In all tests, the M1 native version of Chrome performed 66% to 81% higher than the Chrome version of Rosetta 2.
According to Ars Technica, the Speedometer test can best simulate real-life usage, which is the biggest difference between the two browser versions. Jetstream 2 can best imitate web applications such as spreadsheets, while MotionMark 1.1 can measure complex graphics animation technology.
