I'm not sure I understand this. How will the M1 hold the computer back when an equally fast Intel chip or M2 wouldn't? As more apps become native, they are going to run more, not less, efficiently.
think just like ipad, if you don't do parallel task it should be okay enough.. if you do high end weird thing parallel like server don't..

Sure but wouldn't that also affect you now? The way the claim was phrased made it sound like because the M1 is a first-gen chip, its going to hit an artificial roadblock in a couple of years just because its the first chip in the line.

I can still use my iPad 2 for email, watching videos and running some Apps but there are a lot of Apps that won't run on it. But that's okay. It's almost ten years old. The battery is still fine, the screen is great and it's still usable. And I can make use of it. I still have an iPad 1 that I haven't turned on in a few years but I should turn it on just to see if it can do anything.

The M1 is far more though given that it's being compared to high-end chips these days.

My oldest working computer in the house is from the 1970s - I used it in the past week.

I'm a bit confused with youtubers claiming that this unified RAM is more "efficient" and thus you don't need as much. Huh? RAM is RAM. The efficiency doesn't mean you suddenly need less RAM. It's like saying you can use a 512GB SSD to replace a 1TB HDD because the SSD is faster.... The speed and efficiency, to my understanding, has nothing todo with the amount. It's up to the OS to manage the RAM.
Not necessarily. Things don't need to move from RAM to GPU back to RAM with Apple SOC. GPU can directly access the RAM contents since its unified. That one scenario has major benefits.

Not to mention it has been reported that NSObject is much faster retaining/releasing on Apple Silicon

I am ready to push the button on my M1 Pro but am leaning towards 16GB as I have always chosen to upgrade RAM in the past and have never regretted the decision. My use case where I think I might need is for video and photo editing in Adobe.

I am now reading so many reviews that the M1 is a new paradigm and 8GB seems to be more than enough for anyone but the most demanding users.

Making it harder is the fact that all of the models available through third party re-sellers like Amazon offer discounts of up to 5%, but they are limited to 8GB models.

I am biased to go for the 16GB anyway, but still foregoing the discount makes the net price of the upgrade very expensive.
what did you buy its been weeks since you asked

Intel really hasn't been impressive for many years. I didn't really gain that much performance going from a 2010 Mac Pro 6-core to a 2019 i9 iMac 8-core.

Year after year the iPhone and most of the time iPad SOCs have been major improvements. I would expect the M2 to be much better.

I like the idea of decision tree in this case of selecting appropriate ram. But your tree is incorrect and doesn't take the important things into consideration like resale value, security, scope of use, non-upgradability, etc.. So i will modify it :-
1. If you just want to try these new M1 machines for a few weeks/months and don't plan to use it long term, get 8GB of ram.
2. If your existing machine has 16GB or more RAM, then get 16GB.
3. If your existing machine has less than 16GB RAM, and you are wondering if you need 16GB, just get 16GB of RAM.

Only those who are absolutely sure that they can get away with 8 GB of ram should get it in 2020/2021.
I believe regular consumers who are wondering if they need 16GB of RAM probably have usage that don't demand 16GB of RAM. If they did, they would've already gotten 16GB RAM or more on their current machine, or they are already having poor experience on their current machines with less than 16GB of RAM. Imo those who actually need 16GB RAM already know that they do.

Apple obviously won't mind people paying more than what they need. :D For users who don't have issues with current machines with 8GB of RAM or less, they probably don't need 16GB of RAM.

That's current usage though. You might need to run some application in the future that requires more.

Firefox back around 2001 and 2002 (named Phoenix and Firebird back then) used to run in under 100 MB of RAM. Today I see it using 3-5 GB of RAM.

a little effect but since most the webapp in the server linux, should be okay. Not yet bought because low low /non here. Maybe around jan/feb will be bought Mac mini.

Well, 20 years is a long time to be future proofing. :D Extrapolating from your example, than people should be buying computers with 128GB RAM at the least.

Thanks! I am not a power user, but in my current Intel machine with 8GB I am feeling the pain right now and it seems crazy that Apple would sell a "Pro" machine in 2020 with 8GB unless that secret sauce really is something special.
This is the kicker to me - why Apple would sell a "Pro" model with only 8 GB (even the older i5's from 2020 with the same); I had the 2020 13" with the 8th Generation i5 with 8 GB RAM, and going from that to the M1 with 8 GB - I have not had any issues. I'm not using the computer for anything hard core in terms of video rendering or photo editing - though I do dabble; and the 8 GB is PLENTY for me. I would also add that the base model seems to run my only real "game" I play - World of Warcraft - on high setting without hiccups (which is a huge improvement from my older i5 model)! I think I would have generally upgraded had it been available sooner than it was, and may end up exchanging it down the road if I really really want to; but I am super happy with the new M1 I got (plus Apple does charge incredibly high prices for RAM).

My latest computer has 64 GB of RAM and I do plan to upgrade to 128 GB eventually. It will take up to 256 GB.

But still, the M2 being noticeably faster won't hold an M1 computer back? The only thing that can cause the M1 to hold you back is for your usage to change drastically; like going from word processing to 3d animation.

@OldMike thanks for the tool suggestion, I have downloaded DriveDX and ran it, the result is attached.

Looks like the result is identical to smartmontool in terms of block count, but the same block count yields a different TB count. DriveDX reports 6.1TB write, while smartmontool reports 6.7TB write.

What are the values and raw value for Life Percentage Used under Health Indicators in DriveDX? Actually, maybe you can just post a screenshot of that screen.

I'm using a cluster of three systems right now:

2008 Dell XPS Studio with 48 GB RAM
Late 2009 iMac 27: with 16 GB of RAM
2015 MacBook Pro 15 with 16 GB of RAM

So 72 GB of RAM across three systems. I spread my applications out over the three systems on three monitors.

It is seriously nice to have a lot of RAM on these old systems as performance is decent to very good, even on these ancient systems.

So at least you have similar results between the two. If you have questions about the results, I would be willing to bet that BinaryFruit would answer any questions you might have about the accuracy of results DriveDX is showing.

I have not looked into the specific version of Apple SSD you have, but DriveDX actually compiles a database of individual drives and their statistics in order to create their health and life ratings.

With only 4 days of usage, I am not surprised that everything has a 100% rating. I have an older Samsung 850 EVO that is at least 3 years old that still shows 100% for all ratings as well.

Unless you learn otherwise, it appears your numbers are correct in the amount of SSD writes that are taking place due to memory swap.

Based on that, I am going to say that my assumptions in my previous post are close to correct and that systems which heavily rely on swap for memory put a great deal of wear on an SSD. I was assuming it was possible to see 100 GB of writes per day for normal usage, and you were seeing 30GB / day with no usage to 230GB / day with intense web browsing. The most alarming figure was the 1.2TB written for 3 hours usage of Xcode.

At this point, with indicators leading to the fact that the 250GB SSD only has a rating of 150TBW, I am going to have to say that my opinion is that 16GB RAM is a requirement for anything other than just casual usage. Although the internal SSD may last far beyond the TBW rating, I would not personally be comfortable with going way beyond that rating on a non removable drive.

That being said, if you are only planning on keeping the M1 for a year, or are planning on selling it when the next model arrives, the 8GB RAM model is attractive.

I don't consider myself to be cheap, but I definitely don't like being taking advantage of. Now I am going to have to get over the mental hurdle of paying $200 for $25 worth of RAM ?
