After being shown off via Samsung’s latest ad campaigns and confirmed by AnandTech, the iPhone 5 indeed has 1GB of RAM. Being such hardware geniuses as they are AnandTech dug up Samsung’s product guide to find more information about the iPhone 5′s processor which is given the ID number: K3PE7E700F-XGC2.
Apple thankfully didn’t obscure the details of its A6 slide at the launch event, which gave us a Samsung part number: K3PE7E700F-XGC2. Through crafty navigation of Samsung’s product guide, Brian Klug got us the details. The K3P tells us we’re looking at a dual-channel LPDDR2 package with 32-bit channels. The E7E7 gives us the density of each of the two DRAM die (512MB per die, 1GB total). The final two characters in the part number give us the cycle time/data rate, which in this case is 1066MHz.
Performance wise the A6 chip has 33% more peak memory bandwidth as compared to the iPhone 4S but its still less than that of the iPad 3 which runs at a much higher resolution.
We’ll just have to wait for further benchmarks to see how the iPhone 5 compares to other smartphones in the market.
