RAM list: This is how much RAM the iPhone has (all generations)

In order for the iPhone to function, it needs RAM. The memory, also known as Random Access Memory (RAM), is used to execute programs and enable the calculations of their individual operations in combination with the CPU. It makes sense that Apple doesn't provide any official information about RAM, since the proprietary system of hardware and software is coordinated with each other. So Apple doesn't have to compete with the increasing GB numbers of its Android competitors. Still, it's interesting to see how much RAM the iPhone has - from the first model in 2007 to the iPhone 15 Pro Max in 2023.

How much RAM does the 2007 iPhone have? How much RAM does the 15 iPhone 2023 Pro Max have? Here you can find the list with all models, memory sizes and LPDDR generations.

Overview: This is how much main memory (RAM) the iPhone has

Not only the amount, but also the type of RAM in the iPhone has changed over the years and decades. While the abbreviation for mobile RAM, namely LPDDR, has remained the same, the clock speeds have increased with each new generation. In addition, the required voltage could be reduced. There are details about this at Wikipedia. In the following table, however, the LPDDR generation is also noted for each device so that you can assign them accordingly.
