Shortly after the launch of the iPad Air and iPad mini, Apple has updated its iMac lineup with two variants. The company has unveiled an update to the 21.5-inch model, as well as making changes to the larger 27-inch variant. For those users who were looking for more performance underneath the hood, you’re getting exactly that. Even though the design of these machines has remained the same compared to its predecessors, the performance increase is something that power users, creative professionals, and others will be very happy to witness.

If you’re looking for the best possible performance, you’re going to have to purchase the larger 27-inch 5K iMac, which now touts Intel’s 9th-generation CPUs that can be configured up to eight cores. Apple claims that these new chips can deliver up to 2.4 times faster performance compared to the previous generation. As for the 21.5-inch 4K iMac, this product can be configured up to a 6-core 8th-generation chip, with the company claiming up to a 60 percent performance boost compared to the previous iteration.
