Jetstream2 is the broadest of the three benchmarks and includes workloads for data sorting, regular expression parsing, graphic ray tracing, and more. Speedometer shows a massive advantage for M1 silicon running natively, whether Safari or Chrome Chrome x86_64 run through Rosetta2 is inconsequentially slower than Chrome running on a brand-new HP EliteBook with Ryzen U CPU. This is probably the most relevant benchmark of the three for "regular webpage," if such a thing exists. The first benchmark in our gallery above, Speedometer, is the most prosaic-the only thing it does is populate lists of menu items, over and over, using a different Web-application framework each time. dmg is available today, and-as expected-it's significantly faster if you're doing something complicated enough in your browser to notice.

That was and still is a true statement we find it difficult to believe anyone using the non-native binary for Chrome under an M1 machine would find it "slow." That said, Google's newer, ARM-native. Further Reading Hands-on with the Apple M1-a seriously fast x86 competitor In our earlier testing, we declared that the previous version of Google Chrome-which was available only as an x86_64 binary and needed to be run using Rosetta 2-was perfectly fine.
