Well sure if the ssd really is that fast as you say. Because in my MBP 2019 it is nothing like that, probably 1/3 of that reading and even less writing, so unless something chances dramatically in SSD they use I find it hard to believe. Sure that ssd transfer rate you mention, is possible and pretty norm for NVMe drive you can buy separately for very cheap.
im just going by their specs.

I'm fine with 8GB memory with my MBP 2019 but I'm afraid you cannot compare directly to ARM based CPU. From what I understood ARM basically needs much more memory than x32/x64, so that 8GB with ARM equals roughly the same as 4GB with Intel, since CPU architecture difference. Not sure if is somehow different with M1 but I don't see why it would?

If that was the case, why do the new iPhone 12 Pros ship with only 4GB RAM, and the iPad Pro only 6GB? The other thing that many people are missing is that since the RAM is on the SoC itself rather than on the opposite side of the I/O bus, page ins and page outs to/from RAM will happen at a significantly faster rate than any Intel or AMD system currently on the market.

As far as I know 12 Pro’s come with 6GB!

Anyway, I don’t think it is fair to compare IOS with MacOS, the latter one is much more complicated system compared simplier phone and tablet use interface programs.

So it says somewhere their all SSD’s in M1’s have 3300MB/s transfer rate and not just largest sized options, or what you mean? Could you post a link to specs sheet you saw that mentoned they all are equally fast. Because I surely cannot say my MBP 2019 basic size SSD is anything close to that fast.

can you point me to where it says there not all the same speed?

Not seen that either. Just going by what I have tested myself with my MBP 2019 and I can say smaller drive is much slower than bigger optional models. But maybe they have finally made change and no matter what size you get, it is equally fast. I guess we’ll see in few days who guessed right.

Generally speaking I've found that people who say "8GB is enough" (or even 16GB) don't do any serious work on their computer outside of browser cloud apps (and even those can hog memory). Once you have multiple apps open, web servers running for development, dumb huge Electron ""apps"", multiple browser windows with 20+ tabs open in each, email client, IDE, etc. all open you quickly see how 64GB should be an option for laptops.

There was benchmarks of 256GB SSD already. It is not 3300MB/s (write was around 2000MB/s or so), but still it is higher than it was in previous models, so some improvement is there in smaller ones too in M1 series.

it's okay, but we're approaching 2021 and 16 should be the norm. Even if you're running garage band and using lots of sampled instruments, more ram would be helpful.

I hear many people complain 8GB is not enough, in What world is 8GB RAM is not enough?!

There are like full 3D HD games that are not 8GB in size. Am I missing something?

If you do photoshop with 1000 layers or build 3D worlds for MMORPGs in MAYA this entry laptop is not for you but I can't imagine 8GB not enough, the iphone and ipads are running on 4 and 6 and people are very happy with them. I remember a time when 1GB RAM was a machine for "creative" work.


And $1300 laptop is not expensive, this is cheap! Laptops used to cost north of $1500 easy of weak specs! Steve Jobs introduced the ibook in '99 for $2500+(FFI) to make it "within reach of education customers and consumer customers" ! (btw it had 0.032GB RAM and 6hr battery) I feel old...
I currently have 4 tabs open in Firefox, a couple of word docs open, Mail, Outlook, calendar, Messages, and a pdf document.
I also have Dropbox, Avast, a couple of text formatting apps, and Google Drive open. And I use 10.26 GB.

This is fairly minimal for me as far as when I work. My "typical" usage as I open a couple of more work apps, I use around 12.50 GB.

I've tried to get below 8GB, but I've found it hampers my ability to be productive as my work requires me to move between various apps (none of which are demanding apps in and of themselves). (I'm on an Early 2013 15" MBP).

Sure, everyone doesn't need 16GB. But it's easy to imagine a world where 8GB is not enough.

All you're demonstrating is that MacOS doesn't waste memory. It commits as much as it has to various things. I bet your memory pressure is bellow 10%.

I have 64GB in my iMac, and it will use all 64 of it just sitting around doing light tasks, but that does not mean it NEEDS that much, it's just making use of available resources for things like caching.

My memory pressure at that point is non-existent. But load some heavy apps, spin up some VM's and my pressure climbs and memory compression starts happening. Still no change in performance.

Good point.

Is there a way to see an actual % number? All I'm seeing is this (see attached)

Side note: Wouldn't the caching make the computer speedier?
