The difference is especially large in single-threaded performance
Shortly after the release of the last three Macs, device benchmark results emerged in the popular Geekbench 5 benchmark. Data shows MacBook Pros based on the Apple M1 SoC @ 3.2 GHz in single-threaded mode are 1717 and 1714. In multi-threaded mode, laptops reach 7423 points.
Apple M1 SoC in new MacBooks is noticeably faster than Intel Core i9-9880H in MacBook Pro
At the same time, the MacBook Air with the same single-chip system scores 1656 to 1732 in single-threaded mode and reaches 7545 points in multi-threaded. By using the same platform, the new MacBook Air and MacBook Pro perform broadly similar results, but the MacBook Pro has a cooling fan that the MacBook Air lacks. This means that its performance can be better with longer use.
Also noteworthy is the comparison between the new Mac and the 16-inch MacBook Pro based on the Intel Core i9-9880H processor. It scores from 1041 to 1215 points in single-threaded mode, and when using all cores, the results range from 6464 to 6812 points.
Based on the Geekbench 5 benchmark, the 16-inch MacBook Pro with Intel Core i9-9880H is slower than newer Macs. The difference is especially large in single-threaded performance.
