Nothing except CPU manufacturer choices. Mac laptops use it and they're consumer products.
People will have to get used to buying a fixed amount of RAM with their CPU but thats unlikely to be a problem.
- chessgecko 8d agopretty sure its lpddr not hbm.
- addaon 8d ago> Mac laptops use it and they're consumer products No, Mac laptops use LPDDR, currently LPDDR5X.
- nomorewords 8d agoThe normal non-tech-savvy person already does this. They simply don't know that their ram is upgradeable or something else breaks first, before having to touch ram.
- dylan604 8d agowhat is this too much RAM thing you mention? I thought the only valid RAM situation you could find yourself is not enough RAM. Too much? That's just fantasy
- KeplerBoy 8d agoMacBooks use regular soldered lpddr5(x) RAM. Same RAM as every other laptop manufacturer, they just use more lanes to achieve a higher bandwidth.
- bunderbunder 8d agoPerhaps more noteworthy for general home and business computing, doesn’t it also allow for lower latency?
- Rohansi 8d agoMore channels or soldered memory? Channels are basically RAID 0 so it depends what you're measuring. Soldering memory down was the only way to use LPDDR5X so if you wanted the best memory you had to solder it down. LPCAMM2 exists though so newer devices can use that instead of soldering them down, but not all devices would be able to fit the required LPCAMM2 slots.
- throwaway85825 8d agoSOCAMM2 allows for removable ram in nearly 0 added space.
- Rohansi 7d agoThat's tiny! But it still depends a lot on form factor. LPDDR5X is used in phones and making memory removable would have its compromises. You may even have compromises in laptops. Look at how tiny a MacBook Air's mainboard is and you'll see the RAM modules on the same package as the SoC. SOCAMM2 is too large for that but a variant with only two modules could possibly work.
- Melatonic 7d agoI bet it could fit. It just do a combo of soldered ram and non soldered like many laptops used to.
- fooker 8d agoApple's "unified memory" marketing is so strong that even tech literate people seem to have this misconception! They have managed to pull this sort of thing off many many times. https://en.wikipedia.org/wiki/Reality_distortion_field https://en.wikipedia.org/wiki/Reality_distortion_field
- Rohansi 8d agoYup, the only reason Macs have higher memory bandwidth is because they use more memory channels, which gives them a wider bus. Both Intel and AMD only allow more than dual channel memory on server class processors these days.
- kstrauser 8d agoThe “Apple only does X better because they do Y” thing has been a meme for ages. I remember dismissals like “PowerPC is only faster at math because it has more integer units” or something along those lines, and thinking, uh, isn’t that a good thing?
- JohnBooty 8d ago"You're only better than me at sports because you practice more and try harder!"
- pixl97 8d agoDepends on the expense trade off. If I get 10% more performance for 50% more cost it really depends on one's needs, for example.
- Rohansi 8d agoI am just saying it's not magic and x86 is capable of doing the same. Quad channel memory used to be more common in consumer hardware but now it looks like you don't even have the option anymore for desktops. AMD's Strix Halo was the first sign to reversing that (it has quad channel memory!) and hopefully we see more of that in the future.
