As noted by MacRumors, new Geekbench benchmarks show that the 24-inch M1 iMac, which should begin arriving to customers next week, is up to 56% faster than the previous high-end 21.5-inch all-in-one.
The M1 iMac boasts an average single-core score of 1724 and an average multi-core score of 7453, aggregated from three benchmarks that are currently available.
Regarding the Intel-based all-in-one, benchmarks are for the iMac21,1 — which MacRumors notes is likely the entry-level option with an 8-core CPU, a 7-core GPU, and two Thunderbolt ports. The M1 iMac benchmarks list 8 CPU cores and a base frequency of 3.2GHz, and they’re running macOS 11.3.
The previous-generation high-end 21.5-inch iMac earned a single-core score of 1109 and a multi-core score of 6014, so the M1 iMac is 56 percent faster when it comes to single-core performance and 24 percent faster when it comes to multi-core performance.
