I think they got it wrong. I would pay money to NOT have the touchbar.

I got one of the MBP with the touchbar this year after holding out for many years (changed jobs so had to change laptop). Man it is so much hard to do the volume changes, and there has so far for me been zero benefit.

Easiest way is to press and hold the Touch Bar on the volume control button and slide your finger left or right–that way you barely need to look at the Touch Bar.

Out of curiosity, how many people are actually constrained by 16GB of RAM? What applications are you using it for that 16GB vs 32GB is actually a deal breaker for you? Thinking about your average end-users, like most of my family, 8 to 16GB is about all they need for their systems (and if software were better written they'd probably need less). So is this specific work like machine learning? Video and image processin…

This comment reminds me of the classic "640K ought to be enough for anybody" quote.

it's not, is that 16gb of ram is actually enough for 99% of people. I see many more downsides on the lack of upgradeability after buying it and on the cost of the ssd and ram factory upgrades than on the lack of availability of a 32gb ram version, which will probably follow up when they make the new revision of the soc for the 16 inch laptop and to replace the higher tier 13 inch intel models, that they are still selling with 32gb if you really need that amount of memory.

The Pro is quoted as 2.8x the 1.7 GHz i7. Not Intel's fastest chip but, if these benchmarks are correct, that's a big speed bump and the higher end Pro's are to come. How fast does it have to be in this thermal envelope to get excited about?

I'd wait for actual benchmarks just judging by the amount of parachute clauses in the disclosures. Power consumption numbers should be great but I'm guessing it falls flat on some compute tasks that can't leverage custom instructions.

From Anandtech:

"Apple claims the M1 to be the fastest CPU in the world. Given our data on the A14, beating all of Intel’s designs, and just falling short of AMD’s newest Zen3 chips – a higher clocked Firestorm above 3GHz, the 50% larger L2 cache, and an unleashed TDP, we can certainly believe Apple and the M1 to be able to achieve that claim."

Not sure what the custom instructions you're referring to are.

Personal opinion, no insider info I think it's a good CPU, but I don't think it'll be a great CPU. Judging by how heavily they leaned on the efficiency, I am pretty sure that it will be just good enough to not be noticeable to most Mac users. Can't wait to see actual benchmarks, these are interesting times.

You skipped the keynote parts where they say faster 2x, 4x, 8x... and they say faster than every other laptop CPU and faster than 98% of laptops/PCs in their class sold last year? They said it several times. But I agree... let's wait for the benchmarks (btw. iPads already overturns nearly all laptop CPUs)

For how often they repeated "faster", I was surprised to see them announce no benchmarks with some sort of baseline or context. Fast than what at doing what?

Does anyone have any clue how/why Apple has such different architecture than others and if it's so useful for power/perf. why are others not following the trend. Even if it's not applicable for x64 due to different instruction set, it should still apply to other ARM vendor.

I'm referring to Anandtech article's claim that they have a 8 wide decode (vs. zen 3's 4), 600+ estimated ROB and 192KB instruction cache. Note I'm not a cpu expert but I know these are hugely different from other high performance chips out there.

For the first time in a while I'm actually excited to see what is possible when the hardware and software are built by the same company. These CPUs aren't meant for professionals but 18 to 20 hours of battery without all the heat from Intel CPUs is really nice. Shame they didn't mention clock speeds

Current intel ones supposedly have 10-12 hours of battery, and many times i find that they don't even get to 3 hours, leave open a browser tab that uses webgl or an app that uses the discrete graphic card, and you are doomed. At least on the 16" inch, I'm very disappointed with the battery life.

>Real competition for Intel AMD would like a word.

I'm really worried that AMD has won the battle, but lost the war in terms of x86 being replaced by ARM in the next decade.

Well it is not like x86 was homegrown at AMD either, it is unreasonable to think they will be able to build great products on ARM.

The iPhone has a very smooth process of upgrading the phone. You turn on the new iPhone next to your old one, it prompts and voila. It's like upgrading hardware of your current phone. I'm unsure if we're at a point where these things are even feasible. e.g I have configured my MBP a lot, the .zsh file, home directory and endless configuration. I would not be surprised if they ditch the kernal completely, and make eve…

You can do something similar with Macs. Using Migration Assistant I was able to transfer all my data (.zsh, git repos, configs, Docker containers, everything.) Took less than an hour. In fact, I did this because I needed to upgrade my RAM

Yup, did this when I upgraded from a 2013 MacBook Air to a 2018 MacBook Pro. Everything worked great except for homebrew, which unfortunately had to be nuked and re-installed; but I can't really blame Migration Assistant for that.

So there is an interesting trend here in the comments because HN is very developer focused. Everyone seems to say "well this does not work for my XXX because of RAM, etc." I would say yes, no surprises there! With this line up Apple is fine with that, because the Air and 13" are not targeted at you. This is the laptop for my wife or kids that use it for school, web, some music and video, nothing at a professional lev…

It is literally called Pro if that is not for professionals then what is ?

its $1,000+ price tag is pretty steep if exclusively targeted towards consumer market.

Also the wife and kids have plenty of alternative devices including the iPad to do basic school, web and multimedia, the value prop for just that market is not convincing enough for me

Why would I buy and iPad and MB Pro if they are basically going to do the same type of work ?

Amazing when Steve announced the transition to Intel, he also mentioned the transition to Mac OS X and how that should set up up for at least the next 20 years... That was almost 20 years ago... I can see a new OS for Mac soon that maybe brings OSX even closer to iOS?

> Amazing when Steve announced the transition to Intel, he also mentioned the transition to Mac OS X and how that should set up up for at least the next 20 years... That was almost 20 years ago... I can see a new OS for Mac soon that maybe brings OSX even closer to iOS? You're a little confused. Those were two very separate transitions. Mac OS X came out in 2001. Intel Macs came out in 2006.

In his announcement of Intel transition he referred back to the change from OS 9 to X and how it would be good for the next 20 years...
