AnandTech has revealed the new iPhone 5 has 1GB of 1066GHz RAM and a Samsung-built A6 processor. How did they figure this out? They got the information from Apple’s A6 keynote slide, where part numbers were clearly visible on the chip:
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.
Pretty awesome detective work. Earlier today, we reported AnandTech discovered the A6 SoC also contained its own Apple-designed ARMv7 core, as opposed to previous Cortex A9 cores found in the former A5 chip.
So it looks like Samsung’s earlier misleading ad was true–the iPhone 5 does indeed have 1GB of RAM.
