Because 8GB still works fine and will continue to work fine for at least the next 6-7 years. Cheap Windows laptops and Chromebooks still come with 4GB ram.

I'm currently typing this on a 2008 MacBook Pro with a 2.5GHZ Core 2 Duo and 6GB RAM. It's playing a 1080P video on a second monitor and has 5 browser tabs open in two browsers. Currently using 4.7GB RAM and 60% CPU.

You must have a very different definition of "fine" than me. Only getting OOMkilled several times per hour is OK?

Under normal circumstances it doesn't affect much. Increase the memory on your configuration and move on.

However, when the supply chain is crunched (as it is now), Apple's build-to-order MacBook Pros take two months to deliver. This means that the only available models to purchase immediately from retailers are the low end models that don't cut it.

I doubt it will ever change though. There is more profit in keeping the price low for customers that don't know any better rather than accommodating business customers that need something workable immediately.

Earlier quoted context omitted.

The base 13" model has 8GiB.

That’s the 2020 model, no?

It is. It's the first M1 model still with the touchbar and the old display. So far it hasn't been discontinued, but de-facto replaced by the current 14 inch model.

The 8GB in the newest model is way better than in model from 2015. Way higher throughput matters a lot with M1. Also, very fast NVMe means that swapping disk is way less painful than on older laptops, especially those with HDDs.

Still, 8GB is simply not enough for anything close to "pro" needs.

Because it’s cheaper that way. It’s generally the second most expensive component in the system.

Compression for memory on macs has probably removed a lot of this pressure to increase beyond 16gb.

For the arm solutions moving the memory on package also may be a limiting factor, since there is only so much space available.

Lastly since macs have memory fixed to the package or motherboard failure is expensive, since you’re replacing an entire system board. They have about a 1.5% afr.

The 14in is 60% more expensive than the 13in for the base models and Apple are still selling the 13in as current on at least the regional website. So that doesn't count as replacing to me

True. I guess it's the slightly enhanced version of the M1 Air. Additional connectivity, touchbar and a fan for sustained loads. If that's not required, might as well save the $400 and buy an Air as they're the same in all other aspects.

The commenter didn't say they were getting hit with OOMs. Is this something that is happening to you?

I used to hit OOMs on my 16GiB Macbook Pro pretty regularly, but that was IntelliJ + Docker + MySQL + Chrome + Debuggers + Google Meet + Slack

Someone using Chrome + Facebook or even a dev writing e.g. Python in VS Code to run locally is probably less likely to hit that.
