iPhone 5 A6 has 1GB of RAM, double the RAM of iPhone 4S

With the iPhone 5 we get a much faster CPU and GPU, but what about RAM? Most new smartphones these days pack 1GB, but Apple made no mention of any RAM bump while announcing the iPhone 5. According to new report, the iPhone 5 packs double the RAM of the iPhone 4S, measuring in at a full 1GB. This isn’t particularly surprising, as the 512MB in the iPhone 4S is starting to look positively last-gen. ifans seems to corroborate those claims, citing a forum member as saying the same thing about the amount of RAM packed inside the A6 SoC.

The highlighted part of the image lists part number “K3PE7E700F-XGC2″. Each highlighted E7 refers to a separate 4 GB LPDDR2 die. The A6 features a dual-channel LPDDR2 memory interface, thus requiring two 32-bit die for both channels. 4 GB X 2 = 8 GB = 1 GB of Samsung LPDDR2 RAM. Both processors have the same markings (made by Samsung) and can be found in the Samsung Galaxy SIII (also 1 GB of RAM) branded as Samsung Exynos 4412.

Referring to Samsung’s 2012 Product Solutions Guide (PDF). Kyle Wiens from iFixit has additionally confirms that iPhone 5 packs 1 GB RAM. The solution guide list a chart (as shown below) showing part numbers of various memory parts they have for sale. The A6 part number sits well with the family of 8 Gigabit mobile DRAMs which translates into 1GB of RAM.

We will have to wait for iPhone 5 to be disassembled to confirm this as Apple typically doesn’t reveal such details. The combination of a souped-up chip and double the RAM should make for a phone that packs plenty of speed. What do you think? Via [Macrumors]
