We’ve all seen the performance hit that Apple Silicon Macs suffer from when running x86 emulation through the company’s translation layer, Rosetta 2. However, even with the M1 MacBook Air emulating x86 with that performance decrease, a new benchmark has surfaced, showing that Apple’s latest Mac can outperform every single Mac model out there, at least in the single-core department.

Previously leaked performance numbers showed that the M1 MacBook Air comfortably thrashed the 16-inch MacBook Pro armed with an Intel 8-core Core i9 chip. It also outpaced Apple’s $5,000 base 2019 iMac Pro in single-core workloads and was only 8.5 percent slower than the workstation in multi-core test results. This certainly reveals that Apple’s 5nm M1 chip delivers a torrent of compute punches when it needs to and still manages to hold its own when Geekbench 5 is running through Rosetta 2.
