8GB RAM on M3 MacBook Pro ‘Analogous to 16GB’ on PCs, Claims Apple::Following the unveiling of new MacBook Pro models last week, Apple surprised some with the introduction of a base 14-inch MacBook Pro with M3 chip,…
RAM is RAM. If you’re able to manage it better, that’s nice, but programs will still use whatever RAM they were designed to use. If you need to store 5 GiB of something in memory, what happens with the other 2.5 GiB, if they claim that it’s 2x as “efficient?”
RAM is not RAM though. If a RAM is twice as fast than some other RAM, then it can swap shit back and forth really fast, making it more efficient per size. Because Apple is soldering ram next to the chip, it enables them to make their RAM a lot faster. M3 max’s ram has 6x more bandwidth than ddr5 and a lot lower latency too.
Also macos needs less ram in general. Is 8gB ram enough? No. But i would bet money on 12gB m3 over 16gB pc to have fewer ram issues and faster performance.
Most of the things that “use” ram on every day pc use, dont need ram. It is just parked assets, webpages, etc. Things that if you have a really fast ram, can be re-cached to ram pretty fast, especially if your storage is also really fast.
Of all the points in their blatantly wrong comment, this probably wasn’t the one to single out. The reason for the soldered RAM is due to speed and length of traces. The longer the trace, the more chance there is for signal loss. By soldering the Ram close to the cpu the traces are shorter, allowing for a minuscule improvement in latency.
To be clear, I don’t like it either. It’s one of the major things holding me back from buying a MacBook right now.
Exactly. There is an actual, tangible benefit of doing it that way. I don’t like it, as it creates situations where you’re unable to upgrade your own hardware, but it does make sense for the 95% of the population who has never opened a laptop, let alone tried to replace ram

While this is true on paper, we don’t need to pretend that this is an unsolved problem in reality. It’s not like large-scale motherboard manufacturers simply refuse to put their RAM closer to the CPU, and it’s littered with data loss. Apple also didn’t do anything innovative by soldering the RAM onto their motherboards. This is simply bootlicking Apple for what’s actually planned obsolescence.
I can’t speak for this particular instance but the reason swappable RAM sticks aren’t “littered with data loss” is because they are designed not to. I.e. Only rated up to a certain speed and timings. Putting RAM physically closer to the CPU does allow you to utilize the RAM better. It’s physics.
Personally, I’d rather take a performance hit than be stuck with a set amount of RAM unless there was some ungodly performance gain.

If the RAM was 3x closer, would it somehow be faster? I’m looking for metrics. With the same stick of any given DDR5, how much performance loss is there on a few example motherboards of your choice?
My point, again, is that yes, on paper, shorter wires means less opportunity for inductance issues, noise, voltage drop, cross-talk, etc. But this is all on paper.
It’s not like every motherboard manufacturer doesn’t know what they’re doing and Apple’s brilliant engineers somehow got a higher clock speed than what the RAM is rated for because… shorter wires?
Case in point: DDR4 is meant to operate at a maximum clock speed per the specs of DDR4. However, on plenty of motherboards that are overclock-capable will support memory that is more than 3x the clock of what DDR4 should be capable of. How does this work with memory that is not soldered into the motherboard?
Additionally, without overclocking, the memory is designed to operate at a clock speed. Will shorter traces to the RAM magically increase the capable clock speed of the RAM? Are these the “physics” you’re referring to?
I know I’ve seen something about this topic. I want to say it was from LTT but I can’t find the video.
I didn’t say anything about it being faster. I said utilize it better. Lower latency can be a big help as it allows quicker access. Think of HDD vs SSD. The biggest advantage in the beginning was the much lower latency SSDs provided. Made things a lot snappier even if the speed/throughput wasn’t all that different.
I don’t know what kind of difference we’re taking about here, or how much real world preformance benefits there are but there’s a reason CPUs have caches on the die.
And that doesn’t include whatever other benefits shorter traces provide. Less voltage drop might be helpful.
But, flexibility must still be better than those gains else most manufacturers would have switched. At some point you start running out of better ways to improve performance though. That’s why things are going back to being integrated with the CPU again.
Just a wild guess, I think they mean that the M3 chip can load and unload things so much faster that it doesn’t need as much ram to do regular tasks. Of course, if you are loading video renders into ram, it won’t really apply to it anymore.
Apple is banking on some big companies ordering computers based on “Pro” moniker and that’s the reason why 13" Macbook Pro existed at all. Now that it is gone, 14" base M3 is taking its place. It’s likely to be running basic Excel and PowerPoint so that’s okay for the end user but still mighty shitty of Apple to price gouge on RAM.

I bought a 8gig and I’m usually running apps like Photoshop and Illustrator. I really feel the hit.
Work bought me 16gig M1 and it is noticeably faster when swapping around between apps.
Fuck 8gigs

RAM transfer rate is is not important when swapping as the bottleneck will be storage transfer rate when reading and writing to swap.
Which I doubt Apple can make as fast as DDR4 bandwidth.
What a bullshit I see.

Same way itx boards are preferred for ram oc. But i doubt apple is pushing crazy timings and clocks.

CrApple are just such hardcore money grabbers since pretty much forever.
God damn fucking marketers
Ha! Of course we will see this as a reduction in price, right?.. Tim Apple?.. Are you there?..
“lol” said Apple “lmao”

More apple gaslighting.
Fucking lol
Fucking apple with the dumb ass marketing again. Can’t wait to explain to fanbois you can’t shove 16 lbs of shit into an 8 lbs bag…
Maybe it’s true, but a better headline would be “our systems come with 16gb as standard, which feels like 32gb on windows.”
So you get a good amount of ram, which feels better because It’s a Mac.
