Now that Apple is putting its own Silicon inside new Macs, how much has changed from previous generations? While we can tell you what it’s like to use the new M1-powered MacBook Air, the folks at iFixit specialize in pulling them apart to see what’s inside. In the case of the just-released MacBook Air and MacBook Pro, it turns out that the answer is — not much.
As the explain, the 13-inch MacBook Pro is nearly identical to its Intel-powered predecessor, while the big change in the new MacBook Air is the notably-absent fan. On the MacBook Pro, it appears to have the same fan as the 2020 Intel revision, so any difference in noise comes down to the M1 hardware requiring less cooling under load. The T2 security chip is also gone, with Secure Enclave tech residing inside of Apple’s new PC CPU. Even on the M1 chip, iFixit points out that the SOC memory setup sports two built-on SK hynix LPDDR4X chips, similar to what’s inside of recent iPads.
