    Apple’s M1 is a fast CPU—but M1 Macs “feel” even faster due to QoS / ArsTechnica · Monday, 17 May, 2021 - 20:09 · 1 minute

Apple's M1 processor is a world-class desktop and laptop processor—but when it comes to general-purpose end-user systems, there's something even better than being fast. We're referring, of course, to feeling fast—which has more to do with a system meeting user expectations predictably and reliably than it does with raw speed.

Howard Oakley—author of several Mac-native utilities such as Cormorant, Spundle, and Stibium—did some digging to find out why his M1 Mac felt faster than Intel Macs did, and he came to the conclusion that the answer is QoS. If you're not familiar with the term, it expands to Quality of Service—and it's all about task scheduling.

More throughput doesn’t always mean happier users

There's a very common tendency to equate "performance" with throughput—roughly speaking, tasks accomplished per unit of time. Although throughput is generally the easiest metric to measure, it doesn't correspond very well with human perception. What humans generally notice isn't throughput, it's latency—not the number of times a task can be accomplished, but the time it takes to complete an individual task.

    Apple’s M1 MacBook Air has that Apple Silicon magic / ArsTechnica · Saturday, 28 November, 2020 - 13:15

The new M1-powered MacBook Air is hilariously fast, and the battery lasts a long-ass time.

If you stop reading this review immediately after this, then know that unless Windows virtualization is a requirement of your workflow, you should probably just go ahead and sell your old MacBook Air immediately and get this thing instead.

Assuming you've got a grand or so lying around that you weren't going to spend on something else. But hey, if you do, then I can confidently tell you that in spite of what a legion of Doubting Thomases (including me!) might have said about Apple's freshman effort at its own PC silicon, it is now my studied opinion that there are far, far stupider ways to part with your cash.
