Set up from unboxing in under 2 hours, its CPU cores perform better than those in the M3, differences that are magnified.

One of the most common reasons for opening Activity Monitor is to check the % CPU of processes that might be running out of control. How accurate are those figures, though, and should you believe them?
Comparing CPU core counts and maximum core frequencies across the four families in the M series, plus expected performance of Thunderbolt 5. Which M4 Mac should you buy?
How much faster should a Thunderbolt 3 SSD be for making Time Machine backups? How can you speed up backups to your NAS? Here are representative speeds from real testing.
What can cause low copy speeds for very large and possibly sparse files, such as VMs? Causes explained, and tools you can use to discover why.
Swift 6 claims built-in support for writing asynchronous and parallel code. But these are very different, and that for multithreading appears elusive.
Why an Intel Mac’s up to 40 Gb/s from Thunderbolt 3 is less than an Apple silicon Mac’s up to 40 Gb/s from USB4, and how you can benefit from it.
Memory, from L1 instruction cache to main memory, and how it came to be Unified. Why the internal SSD isn’t like others, and why it’s so essential.
How the NEON vector processor, neural engine, matrix co-processor, and GPU all deliver high performance with low power and energy use.
Running threads at different frequencies on the same core type can’t save energy and extend battery endurance. That’s where 2 core types come in handy.
