There was some mixed information about the RAM in the new 2019 iPhone models, which has led to confusion over the course of the last week.

Benchmarks of the new iPhones have continually listed 4GB of RAM in all iPhone 11, 11 Pro, and 11 Pro Max devices, but a rumor sourced from a certification database suggested there was 6GB RAM in the iPhone 11 Pro and Pro Max.


That led to speculation that perhaps some higher-end capacities might have had 6GB RAM, but it's now been made clear, both through regulatory filings in China and info discovered this morning by Steve Troughton-Smith in Xcode, that every iPhone 11, 11 Pro, and 11 Pro Max model has 4GB RAM.

Xcode also confirms that no model of iPhone 11 or 11 Pro/Max has 6GB of RAM. All models have 4GB of RAM - Steve Troughton-Smith (@stroughtonsmith) September 18, 2019

For the iPhone 11 Pro and Pro Max, that's identical to the amount of RAM available in the prior-generation iPhone XS and XS Max, and for the iPhone 11, that's up 1GB from the 3GB RAM in the iPhone XR.

Also of note, Troughton-Smith has confirmed that the S5 processor in the Apple Watch Series 5 is identical to the S4 processor in the Apple Watch Series 4, with no performance improvements.

According to Xcode, Apple Watch Series 5 has the same generation CPU/GPU as the Apple Watch Series 4; I guess the only changes are a gyro and 32GB of NAND? The plus side of that is that we won't have to worry about watchOS being slower on the Series 4 than on a brand new model - Steve Troughton-Smith (@stroughtonsmith) September 18, 2019

That's not a surprise as Apple mentioned no changes to the chip during its September 10 event and there's no mention of speed or performance increases in the Apple Watch marketing materials, but it's useful to have confirmation.

Internally, the Apple Watch Series 5 is using an updated display that allows for always-on functionality, there's a new compass feature, and 32GB storage, but otherwise, the Apple Watch Series 5 appears to use the same internal components as the Series 4.

Troughton-Smith's Xcode digging has also uncovered new information about the updated 10.2-inch seventh-generation iPad. It is equipped with 3GB RAM, up from 2GB in the previous-generation version.

3GB of RAM on the 10.2" iPad https://t.co/KeFSV7pT5p - Steve Troughton-Smith (@stroughtonsmith) September 18, 2019

Apple's new iPhone and Apple Watch models are set to officially launch on Friday, September 20, and teardowns will soon unveil even more information about the new devices. The new seventh-generation iPad will be available on September 30.

Update: Troughton-Smith now says that he's hearing conflicting information about the RAM in the iPhones and is going to look into it further in the firmware.

I'm hearing conflicting things about this, so I'm gonna revise my wording until I can have a closer look at the firmwares this week: there is 4GB of system RAM, accessible by iOS and apps, in the new iPhones. To the user, it's 4GB of RAM - Steve Troughton-Smith (@stroughtonsmith) September 19, 2019

Hmmm... I don't buy it. That twitter thread is talking about 4 GB system RAM + 2 GB dedicated camera RAM in the new iPhone Pros. However, it would be unlikely to have 6 GB RAM with 2 GB of that dedicated to the camera. If it were to have 6 GB, all 6 GB would normally be available to the OS, and then the camera would use up to 2 GB as needed by killing resident applications if necessary. I'd be happy to be proven wrong, but this 4+2 GB claim sounds more like wishful thinking than anything else.

The confirmation of 3 GB for the 10.2" iPad is a big relief... or it would have been if that linked tweet hadn't been deleted. So who knows? Is it 3 GB or not? That link certainly doesn't inspire confidence:

You wouldn't think this would be so hard to verify. It's back and forth between 4 and 6 since it was announced. Let's just compromise and say it has 5. :p
No it hasn't. It's always been 4 GB. Geekbench says 4 GB measuring actual iPhones. Antutu says 4 GB measuring actual iPhones. Apple's own Xcode says 4 GB. Regulatory filings in China by Apple have said 4 GB.

The only things that have said 6 GB have been 3rd party databases that have nothing to do with Apple. That so-called "certification database" does not certify anything for Apple. It's apparently for an online retail store.

Even it’s 4 GB, it still should be plenty sufficient, the only thing that I would think would might need additional Ram, would be for the ‘triple lens camera’ on the Pro.

I was thinking about getting an Apple Watch S5 as my first Apple Watch, but it feels dumb to buy when there are no performance upgrades and sleep tracking and more significant features are most likely coming next year.

The always on feature is important enough for some. Including me. But if you don't really feel the watch is needed, don't buy it. Really. Although since I own stock, I wouldn't mind if you did. :)

It has become my main running/biking/hiking watch and I love it. Can't imagine not having one. Notifications on the watch really make things easier for me.

If it's your first apple watch, you get all of the features that have been introduced since 2015 as new to you... If you keep waiting for next year because it will be "better" you will be waiting forever. Now is the time to buy one if you are going to. I have an original Apple watch, and plan on upgrading to the S5 as soon as they hit store shelves.

So there is a separate RAM allocation? That would be weird and I doubt it, especially with the battery life these things are getting.

More memory and always-on screen are pretty big upgrades IMHO.
I’m in two minds. By some accounts, battery life isn’t quite as good as on S4 & if there’s no performance/spec upgrade to the S5, there would be no future proofing issues if I saved some money and bought the Series 4 in the expectation of upgrading again next year.

Having broken my series 3 last month I do want another watch but not sure that series 5 is worth the extra cash. Will see first who is selling Series 4 at what price.

If you wait until next year, there will be X new features to tempt you to wait until the following year and on the cycle goes. You will never buy one waiting for next years features, you have to accept that whatever one you buy, in 12 months time there will be people with a new version that has more features.

Could be 4GB accessible to apps and 2GB available only to the system, that could use them for the camera.
If iPhone is getting data from 3 sensor at the same time chances are is going to need a lot of memory for its Deep Fusion stuff, so more RAM could really help, especially if you want to keep some apps in background. Opening the camera app and watching all your app, and Safari tabs reload after that is not a great user experience.

Always on display is a pretty good feature for an "S" year like this. Performance are ok, my series 4 with the same (or very similar) chip is fast enough for everything I need it to do.
If sleep tracking is something you care about then wait, but I wouldn't bother about speed

Shouldn't be a problem since iOS still doesn't have real multi-tasking.
Exactly.

And on iPads which do have real multitasking, even 3GB is enough for that! (mini 5, iOS 13, 3 apps at once - no issues whatsoever)

People are in a furor about this because expectations were incorrectly elevated and now it seems “less than”

I don’t recall an uproar about iPhone 7 or 8 having the same 2GB ram as the 6s being an issue

4GB is probably more than these phones need. When iOS gets real multitasking abilities then perhaps this becomes an issue down the road, but by that point, people complaining about this now will probably have upgraded 1-2 times by then.

When iOS demanded it, Apple has always increased the ram appropriately.
