Apple’s M1 chip: specs, performance, features, and power efficiency

| |

Apple has unveiled its first Macs with Apple silicon, and so they’re powered by an all new Mac-specific chip: the M1. It’s primarily based on the identical basic design of the A14 (discovered within the iPhone 12), however scaled as much as laptop-grade efficiency ranges with extra cores, extra reminiscence, and better thermal limits.

The consequence, Apple says, is a surprising enhance in efficiency and energy effectivity. Right here’s what it is advisable to know concerning the M1 system-on-chip.

Eight core CPU and GPU

The place the A14 has a six-core CPU—4 high-efficiency cores and two high-performance cores—the M1 expands that by including one other pair of high-performance cores for a complete of eight.

We’ve already seen how briskly these cores are in A14 efficiency benchmarks, and with the upper thermal and energy limits of a laptop computer, they need to have much more room to breathe.

Apple doubled its high-performance CPU cores to 4, and nonetheless has 4 high-efficiency cores, too.

Apple has additionally expanded the GPU from 4 cores within the A14 to eight within the M1. Apple says it’s the quickest built-in graphics in any laptop computer anyplace. 

Apple isn’t massive on benchmarks, however does make grand claims like “as much as two instances quicker than the most recent laptop computer chip.” Apple says the MacBook Air with the M1 chip is quicker than 98 % of all PC laptops. Not simply “skinny and light-weight” laptops or “laptops in its class,” however all PC laptops.

A whole system-on-chip

Macs used to make use of a number of separate chips for CPU/GPU, I/O, RAM, and Thunderbolt management—this together with the T2 chip for safety (and different capabilities). With the M1, all of these chips are mixed right into a single system-on-chip.

Among the separate chips now mixed into the M1 system-on-chip.

That’s a double-edged sword. On the one hand, you possibly can say goodbye to expandable reminiscence and most different improve choices. Maybe future Apple-designed Mac chips will enable for normal reminiscence DIMMs, however the M1 contains a single chunk of reminiscence that may’t be expanded past both 8GB or 16GB.
