A8 Chip From 4.7-Inch iPhone 6 Appears to Carry 1 GB of RAM

Last week, a wiring schematic said to be for the iPhone 6 was initially interpreted to be referring to the device's RAM, showing the same 1 GB of memory for the A8 as found in the current A7 chip. That was quickly determined to be an incorrect interpretation of component being shown in the schematic, however, and Apple's plans for RAM in the iPhone 6 have remained uncertain.

A new photo leak from Feld & Volk [Instagram page] and Sonny Dickson showing an assembled logic board from the 4.7-inch iPhone 6 has revealed a number of pieces of information already, and it appears from one of the photos that the A8 chip on the board does indeed include 1 GB of LPDDR3 RAM.

As pointed out by MacRumors forum member commander.data, a silk-screened part number on the A8 reveals that the package-on-package contains Hynix RAM. Based on Hynix's part number format, the character in the eighth position reveals the amount of RAM in the package, with an "8" denoting 8 Gb (1 GB) and a "B" denoting 16 Gb (2 GB). While it is a bit difficult to read the part number clearly given the distance and angle in the photo, our staff and several posters in our forum agree that the character very much appears to be an "8", indicating 1 GB of RAM.

Can't give customers 2 GB ram, cause the incremental cost of that extra GB of ram would ruin the margins, and shareholders would not be happy.

Between this and the 16GB of storage, I feel Tim Cook is a miser.

I'm sure there could be a nice spin on this:

"Enjoy the same, familiar one gigabyte of RAM experience that you've grown to love!"
"One gigabyte of RAM per screen—just the way it was meant to be."
"Get to the heart of your content more directly without all of that pesky, quickly accessed memory."

Can someone explain to me why this is so bad? iOS runs flawlessly, and has been this way for all three iPhones that I've had. Why does the iPhone need more RAM if the os is perfectly optimized for 1GB?


If by flawless you mean the constant reloading on Safari (a problem on OSX as well), frequent app killing, and frequent low memory errors, then yes, iOS runs fantastically on 1GB of memory.

1GB of RAM on an iPhone is no issue. On an iPad, it's an issue.

Luckily, I only have the iPhone so this doesn't bother me!

Because it doesn't run flawlessly and it has needed 2GBs since the A7 came out. First of all, whenever you have to run a 32 bit app, iOS loads 32 bit AND 64 bit binaries, making it more memory constrained than the iPhone 5 or 4s with an A6 or A5. This isn't true in terms of bandwidth, bandwidth is good.
Over time you realize the apps you use are constantly closing, you may be doing something in an app and then switch to another to check something, come back and realize everything you wrote is gone and the app is reloading. It's infuriating sometimes, especially when using something in safari, like to respond to a macrumors post. That time we have to wait for our 3rd or 4th last-used-app is annoying. Facebook and safari almost always have to be reloaded on my ipad Air. I'm limited to multitasking with 2-4 apps. That's hardly multitasking.
Second, most of my crashes in the diagnostics report are for low memory, especially in safari.

Personally the amount of RAM my phone has is just a number. I actually think its a testament to Apples engineering prowess that they can get such amazing results from just 1 GB of RAM. And I appreciate them doing whatever they can to keep costs down.


Except the 64-bit transition cost the 5s about 25-30% of it's available RAM. So no, please don't drink the kool-aid.
