The performance of the M1 processor is similar across all devices, so benchmarks have shown that the new 24-inch iMac significantly outperforms its Intel variants.
The 24-inch iMac was unveiled at Apple's "Spring Loaded" event in April and features an M1 processor. The computer will begin shipping to customers on May 21. Geekbench results have now surfaced in advance. As MacRumors reported, the 24-inch iMac performs similarly well to Apple's other M1-based Macs. Customers can expect a significant performance boost when moving up from the most powerful Intel-based iMacs. Geekbench is a benchmarking tool that attempts to produce an overall score indicating processor performance. Results can be affected by the operating system used, background tasks, and the temperature of the computer being tested. The 24-inch iMac scored 1729 points in the single-core metric and 7459 points in the multi-core metric. This appears to be the entry-level M1 processor with an 8-core CPU and 7-core GPU.

M1 iMac: An upgrade is worthwhile in most cases
Compared to the 2019 21.5-inch iMac, which runs on an Intel Core i7 processor, the M1 is 56% faster in single-core performance. Compared to multi-core, the M1 is 24% faster. The 27-inch iMac with the 10th Gen Intel Core i7 wins in multi-core by a 24% margin. But the M1's single-core performance still won by a 38% margin. These numbers don't absolutely reflect how these machines will perform in everyday use. However, the M1 shows that upgrading from almost any Intel-based Mac won't let users down, provided they don't have workflows that are limited to Intel only. The 24-inch iMac is available in two configurations with seven color options, with upgrade options up to 16GB of RAM and 2TB of storage for each model. (Image: Apple)
