It’s Faster
Naturally, Apple has improved the speed of its iMac across the board, and while you can go a bit crazy and splurge on a new 10-core Intel i9 version, even the base model offers considerably better performance than previous iMacs.
In fact, according to benchmarks by Mac Otakara, the entry-level 27-inch model, which features only a 3.1GHz Core i5 CPU, clocks in at 20% faster on RAW CPU performance than the equivalent 2019 model, and in fact even comes in faster than the third-tier 2019 iMac, which sported an Intel Core i5 3.7GHz chip.
Similarly, the Radeon Pro 5300 GPU offers improvements of 36% in Metal performance and 43% in OpenCL over the Radeon Pro 570X in last year’s iMac.
