That being said, is the new 24-inch iMac worth upgrading to? If you’re coming from the Intel-powered 21-inch iMac, then the answer is yes. This is because according to the benchmarks for the M1 iMac, it has been found to be over 50% faster than its predecessor. The M1 iMac scored 1729 for single-core performance, and 7459 for multi-core performance.
This is versus the 2019 21-inch iMac with an Intel Core i7 processor which scored 1109 for single-core performance, and 6014 for multi-core. To be fair, it is a 2-year old desktop and if the M1 didn’t outperform it, it would be downright shameful. As for the 27-inch iMac, the M1 managed to beat it in terms of single-core scores, but lost out to multi-core performance.
It will be interesting to see what kind of performance we might be able to expect from the 27-inch iMac refresh, which could be taking place later this year and where it might come with a new M2 chipset.
