Iphone 14 pro on safari with no tabs open. I tried it on Microsoft edge too and the result was 298
A new Samsung Galaxy S23 Ultra only achieves 143 runs/min so this is unlikely what Apple is doing here. They achieve similar results in this benchmark as desktop CPUs that can draw 219 W of power.
It is not only in Speedometer, also in Kraken 1.1 the iPhone 14 scores similar to an i9 12900K.
Android uses a monolithic kernel and iOS has a hybrid kernel (hybrid should be slower). But iOS has technology based on FreeBSD. I also see on FreeBSD that Chromium scores 14% higher than on MX Linux, although the Chromium project does not accept patching for FreeBSD. This forces the FreeBSD team to maintain thousands of patches for Chromium. Suppose the Chromium project were to accept patches for FreeBSD then Chromium might also be over 30% faster on FreeBSD than on Linux.
Someone I know has an iPhone 13 with Safari and I can beat Safari on this device with my old i3-3240 and FreeBSD, but only in a limited number of benchmarks, namely the following:
Maze Solver CSS by using Chromium
Chalkboard HTML by using Firefox
Robohornet Pro by using Firefox
But overall, the iPhone 13 scores very strongly with Safari. It is a combination of hardware and optimized operating system. And the browser engine also has an impact. The WebKit engine for the last 5 years has always been faster than the Blink engine that Microsoft and Google continue to cling to. I think Microsoft and Google are allowed to use a WebKit engine from Apple because it's open source. But they probably don't want it because it's so closely associated with Apple.
