8GB RAM in M3 MacBook Pro Proves the Bottleneck in Real-World Tests::Apple's new MacBook Pro models are powered by cutting-edge M3 Apple silicon, but the base configuration 14-inch model starting at $1,599...

For $1,599 you'd at least expect 16GB+ RAM given how cheap RAM is...

I think Apple gets all their RAM from 2008, because they charge $50/GB for it.

Don't they also solder it to the motherboard so you can't upgrade your RAM as well?

[–] [email protected] 49 points 1 year ago (3 children)

It’s not so much soldered to the motherboard as much as part of the same package as the CPU. As in: there are no separate memory chips.

[–] [email protected] 23 points 1 year ago (1 children)

But they did indeed solder it in before that, on their old Intel laptops. I think they started doing that in 2013 or 2014 but I forget exactly.

[–] [email protected] 5 points 1 year ago (1 children)

That has more to do with faster traces; the ram is “closer” to the CPU so the signal is cleaner.

Not defending the move, I’d take upgradability in a laptop.

[–] TwanHE 2 points 1 year ago (1 children)

Only makes a difference at oc levels of manual tuning. Which apple isn't doing at their factory I reckon.

[–] [email protected] 2 points 1 year ago (1 children)

I mean, when you’re the one manufacturing the board, I’m pretty sure you could eek out some more baseline performance without having to tweak each one for OC in the production line, my dude.

[–] TwanHE 1 points 1 year ago

At 100gb/s for the base model there probably actively downclocking the ram to make the higher end models more attractive.

[–] billiam0202 3 points 1 year ago (3 children)

So wait- if you want to increase your RAM, you have to install a whole new CPU?

[–] [email protected] 9 points 1 year ago

That's soldered as well! It's theoretically possible but way too involved for most to bother with hiring a professional to get it done or what have you.

[–] [email protected] -1 points 1 year ago (1 children)

No, you just buy one with the amount of RAM you need.

[–] [email protected] 4 points 1 year ago (2 children)

Imagine buying a laptop at all

[–] ripe_banana 6 points 1 year ago

Imagine spending $400 for 24GB of ram.

Sincerely, another Framework user

[–] [email protected] 3 points 1 year ago

You don’t buy a laptop, you have your employer buy it for you.

[–] [email protected] 6 points 1 year ago (1 children)

Lol, the ram is part of the m3 chip That’s a reason why it is so efficient. The storage in m3 is for RAM and videoRAM.

Wikipedia: The M3's Unified Memory Architecture features up to 24 GB RAM, the M3 Pro up to 36 GB, and the M3 Max up to 128 GB. Like the M2 generation, the M3 SoCs use 6,400 MT/s LPDDR5 SDRAM. As with prior M series SoCs, this serves as both RAM and video RAM.

That's literally how Intel integrated GPUs work too

The RAM being shared with the GPU, that is.

[–] [email protected] 2 points 1 year ago

Yea but the RAM is not on the located within the chip design, is it?

[–] DarienGS -4 points 1 year ago (1 children)

With Apple's chips the RAM is all on the CPU die so both CPU and GPU get the performance benefit. With Intel's, none of it is.

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago) (1 children)

"What Apple calls “unified memory” is RAM (random-access memory) used as “main memory” (not a CPU or GPU cache and not mass storage either).

The term “unified” refers to the fact that the memory is shared by the CPU cores and the GPU cores. That’s not novel: “integrated graphics” options in Intel x86 chips (like Iris Xe) do the same, as do just about all modern smartphones."

[–] DarienGS 1 points 1 year ago

I'm not talking about the merits or otherwise of "unified memory", I'm pointing out that because Apple's RAM is physically integrated into the CPU, it can provide more memory bandwidth than regular DDR5 DIMMs.

[–] [email protected] 5 points 1 year ago

Well yeah, if you were paying $50 a GB wouldn't you too? Got to lock that shit down!

[–] xkforce 3 points 1 year ago (1 children)

How the fuck did Apple manage to be the largest company on the planet doing shit like this? Are Apple users really that fucking dumb?

[–] EatYouWell 21 points 1 year ago (3 children)

Because they have an extremely consumer friendly UI/UX and a very stable OS.

[–] dual_sport_dork 24 points 1 year ago* (last edited 1 year ago)

And they're much better at marketing than they are at making computers or phones. Apple is probably the most successful marketing company in the world.

[–] tabular 5 points 1 year ago

Not sure "friendly" is quite the right word.. you can argue it's well designed or cultivated users but Apple is anything but a "friend"ly.

[–] dustyData -1 points 1 year ago

Their UI and UX is shit. You basically can't use it for many basic tasks without installing a bunch of third party (proprietary and expensive) software.

[–] TenderfootGungi 23 points 1 year ago

Apple loves under ramming (to give a word a new meaning) and forcing everyone to pay for upgrades. The problem is there are always people that buy the base.

[–] [email protected] 2 points 1 year ago

I think the point is to squeeze out a couple extra hundred dollars from customers.

Apple has long done price anchoring with their products just like in this case.

[–] [email protected] 4 points 1 year ago

At this point I'm pretty sure the ram costs more than the rest of the laptop.

[–] DarienGS -5 points 1 year ago (1 children)

Apple's RAM isn't as cheap as you might think, because it's all built directly onto the CPU die. That's part of what makes its computers so fast.
