An 8 core processor on a Macbook Air that is also energy efficient? That is truly impressive. I never thought I would consider using Macbook Airs after all the years of using Macbook Pros, but Apple surprises me once again.

4 high-power and 4 low-power cores.

I don't get it.

If we have same CPU on MacbookAir and MacbookPro - why would I get more expensive "Pro"? Can someone explain how is Pro faster than Air with same CPU?

Also, the "Windows Guy" bit is a bit lame IMO. I have two MacBooks and one custom built PC. The PC is faster than both MacBooks combined.

The iPhone-like speed of waking up from sleep itself is enough to convince many of us to go for the M1 macbooks

How long does it take the current gen of macbooks to wake from sleep, ~1 second?

I genuinely would love some info or statistics on this. AFAIC remember, laptops wake from sleep almost instantly to the lock screen. Is it a longer wait if one wakes directly to their desktop?

I'm with you in not fully understanding the benefit. Maybe this is a technology that is hard to imagine, but is difficult to go back from (60hz, Retina displays).

Apple mentions TensorFlow explicitly in the ongoing presentation due to the new 16-core "Neural Engine" embedded in the M1 chip. Now that's an angle I did not expect on this release. Sounds exciting!

Edit: just to clarify, the Neural Engine itself is not really "new":

> The A11 also includes dedicated neural network hardware that Apple calls a "Neural Engine". This neural network hardware can perform up to 600 billion operations per second and is used for Face ID, Animoji and other machine learning tasks.[9] The neural engine allows Apple to implement neural network and machine learning in a more energy-efficient manner than using either the main CPU or the GPU.[14][15] However, third party apps cannot use the Neural Engine, leading to similar neural network performance to older iPhones.

It's 8-core, but they're 4 performance and 4 low-power cores, so it's not your normal 8-core chip. It's more like a big.LITTLE chip.

Seems pretty clear they're using big.LITTLE-style low-power and high-power cores on the same chip.

No fan however, is impressive....
