The first tests of the Apple M1 processor appeared on Geekbench last week, showing decent performance – the new MacBook Air is even more powerful than the 16-inch MacBook Pro. Now the turn has come to testing the M1 chip in the mode of emulation of x86 applications developed for past Mac models with Intel processors.
According to the results of the Geekbench benchmark, the M1 chip in the MacBook Air with 8 GB of RAM scored 1313 and 5888 points, respectively. This is about 78% -79% of the baseline values. In other words, when emulating x86 applications, performance drops by about 20%, but even then the Air with Silicon M1 in single-core mode outperforms any other Mac with an Intel processor, including the 27-inch iMac with a 2020 Core i9-10910.
In multi-core mode, the emulated M1 scores less than the 16-inch MacBook Pro, but still performs impressively, especially for a passively cooled ultrabook.
It is in emulation mode that all macOS applications will run, the developers of which will not bother to support the new ARM architecture. If you believe the Geekbench numbers, then you can not worry about the drop in performance.
Recall that in addition to the MacBook Air, the 1-inch MacBook Pro and Mac mini received the M13 proprietary processor.
