Apple revealed its iPhone 16 lineup on Monday, and the large promoting level was Apple Intelligence. Apple’s on-device AI system affords splashy options like the flexibility to rewrite emails, generate customized emoji, and a considerably upgraded Siri. However beneath all of it, AI is delivering one different large change to the iPhone: extra RAM.
Though Apple by no means talks about RAM in its smartphones, MacRumors found that each iPhone 16 mannequin now has 8GB of RAM, up from 6GB within the base fashions from final yr. And it’s not simply Apple making adjustments like that. Final month, Google made related adjustments to its AI-heavy Pixel 9; each the usual and professional fashions noticed a rise in RAM, making 12GB the least you may get this yr.
The impetus behind these RAM bumps seems to be synthetic intelligence. AI is the yr’s new must-have function, and it’s additionally extremely RAM-hungry. Smartphone makers at the moment are bumping reminiscence as a result of they should — whether or not they’re saying that out loud or not.
AI fashions have to be fast to reply when customers name on them, and one of the best ways to make that occur is to maintain them perpetually loaded in reminiscence. RAM responds much more rapidly than a tool’s long-term storage; it might be annoying in case you needed to look forward to an AI mannequin to load earlier than you would seize a fast electronic mail abstract. However AI fashions are additionally pretty giant. Even a “small” one, like Microsoft’s Phi-3 Mini, takes up 1.8GB of house, and meaning taking reminiscence away from different smartphone capabilities that had been beforehand making use of it.
You may see how this performed out very straight on Pixel telephones. Final yr, Google didn’t allow native AI options on the usual mannequin Pixel 8 attributable to “{hardware} limitations.” Spoiler: it was the RAM. Android VP and normal supervisor Seang Chau stated in March that the Pixel 8 Professional might higher deal with Gemini Nano, the corporate’s small AI mannequin, as a result of that telephone had 4GB extra RAM, at 12GB, than the Pixel 8. The mannequin wanted to remain loaded in reminiscence always, and the implication was that the Pixel 8 would have misplaced an excessive amount of reminiscence in supporting the function by default.
“It wasn’t as straightforward a name to simply say, alright, we’re simply gonna allow it on the Pixel 8 as effectively,” Chau stated. Google ultimately allowed Gemini Nano onto the Pixel 8, however just for folks prepared to run their telephones in Developer Mode — individuals who Chau stated “perceive the potential affect to the consumer expertise.”
These tradeoffs are why Google determined to spice up RAM throughout the board with the Pixel 9. “We don’t need the remainder of the telephone experiences to sluggish to accommodate the big mannequin, therefore rising the overall RAM as an alternative of compacting into the present finances,” Google group product supervisor Stephanie Scott stated in an electronic mail trade with The Verge.
So, is all of that additional RAM going simply to AI, or will customers see improved efficiency throughout the board? It’s going to rely so much on the implementation and simply how giant these fashions are. Google, which added 4GB to help native AI options, says you’ll see enhancements to each. “Talking solely to our newest Pixel telephones,” Scott wrote, “you possibly can count on each higher efficiency and improved AI experiences from their extra RAM.” She added that Pixel 9 telephones “will have the ability to sustain with future AI advances.” But when these advances imply bigger fashions, that might simply imply they’ll be consuming up extra RAM.
The identical RAM-boosting development is enjoying out within the laptop computer world, too. Microsoft dictated earlier this yr that solely machines with a minimum of 16GB of reminiscence might be thought-about a Copilot Plus PC — that’s, a laptop computer able to working native Home windows AI options. It’s rumored that Apple is planning so as to add extra RAM to its subsequent technology of laptops, too, after years of providing 8GB of RAM by default.
That additional reminiscence might be wanted, particularly if laptop computer makers need to maintain even bigger fashions loaded domestically. “I believe most OSes will maintain a LLM always-loaded,” Hugging Face CTO Julien Chaumond informed me in an electronic mail, “so 6-8GB RAM is the candy spot that may unlock that in parallel to the opposite issues the OS is already doing.” Chaumond added that fashions can then load or unload “a small mannequin on prime of it to alter some properties,” reminiscent of a method for picture technology or domain-specific information for an LLM. (Apple describes its method equally.)
Apple hasn’t explicitly stated how a lot RAM is critical to run Apple Intelligence. However each Apple gadget that runs it, going again to the 2020 M1 MacBook Air, has a minimum of 8GB of RAM. Notably, final yr’s iPhone 15 Professional, with 8GB of reminiscence, can run Apple Intelligence, whereas the usual iPhone 15 with 6GB of RAM can’t.
Apple AI boss John Giannandrea stated in a June interview with Daring Fireball’s John Gruber that limitations like “bandwidth within the gadget” and the neural engine’s dimension would make AI options too sluggish to be helpful on the iPhone 15. Apple VP of software program engineering Craig Federighi stated throughout the identical look that “RAM is without doubt one of the items of the overall.”
The 2GB iPhone 16 RAM bump isn’t finally so much, however Apple has lengthy been sluggish to increase baseline RAM throughout its gadgets. Any enhance right here looks like a win for usability, even when the corporate is beginning small.
We nonetheless don’t know the way helpful Apple Intelligence might be or whether or not a slight bounce in reminiscence might be sufficient for at the moment’s iPhones to run tomorrow’s AI options. One factor appears sure, although: we’ll be seeing extra of those kinds of {hardware} bumps as AI proliferates throughout the trade.
