Apple customers that ordered their new M1 iMacs on the first day of ordering are starting to see their shipping status change to “shipped,” and reviewers that already have them for testing are apparently benchmarking them on Geekbench, and the numbers are impressive.
M1 iMax Geekbench scores are coming in at an average single-core score of 1724 and an average multi-core score of 7453 (from three benchmarks that are currently available).
Benchmarks are for the iMac21,1 (which is likely the entry-level option with an 8-core CPU, a 7-core GPU, and two Thunderbolt ports). The M1 iMac benchmarks show the tested machine as having 8 CPU cores and a base frequency of 3.2GHz, running macOS 11.3.
The new 24-inch M1 iMac leaves the 2019 21.5-inch iMac with an Intel chip that it’s replacing in the dust. The previous-generation high-end 21.5-inch iMac earned a single-core score of 1109 and a multi-core score of 6014. This means the M1 iMac is 56% faster for single-core performance and 24% faster for multi-core performance.
The high-end 27-inch iMac earned a single-core score of 1247 and a multi-core score of 9002. It should be noted that the M1 iMac’s single-core performance is 38% faster, but the Intel iMac’s multi-core performance is 25% faster.
However, the M1 iMac outperforms lower-end 27-inch iMac models powered by Intel chips, beating the 6-core Intel models in both single and multi-core performance.
