When Apple first introduced the iPhone 5 on September 12 it didn’t give us too many details about the iPhone 5 features, only all what we have known that the iPhone 5 have an A6 processor the internals of the iPhone 5 outside of what it lists on the handset’s Features page. But a lot of people began asking about the RAM of the iPhone 5 and wanted more details to know about the iPhone 5.. And here’s what we have got..
Today some smart folks began digging in Apple’s information system and they were able to get some important information and details about the iPhone 5 performance. For instance, they’ve confirmed it has 1GB of RAM…
From the technical wizards over at Anandtech:
“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.”
While 1GB may not be as much RAM as some of the other handsets made by Samsung, and others, have, it’s a welcome upgrade from last year’s iPhone which only had 512MB. iOS is generally pretty resourceful when it comes to memory, but the extra 512MB certainly won’t hurt anything.
After they discovered that the iPhone 5 have 1GB of RAM they also knew that the iPhone 5′s A6 chip is a completely new processor, not just a retooled A5 like originally thought. In fact, the site says that it’s Apple’s own custom creation — its first SoC (system on a chip) designed completely in-house.
“I received some information pointing to a move away from the ARM Cortex A9 used in the A5. Given Apple’s reliance on fully licensed ARM cores in the past, the expected performance gains and unpublishable information that started all of this I concluded Apple’s A6 SoC likely featured two ARM Cortex A15 cores.
It turns out I was wrong. But pleasantly surprised. The A6 is the first Apple SoC to use its own ARMv7 based processor design. The CPU core(s) aren’t based on a vanilla A9 or A15 design from ARM IP, but instead are something of Apple’s own creation.”
The current performance of the new iPhone is great, iPhone 4S have 512MB of RAM.
We still don’t know how many cores the A6 has for sure. Anandtech says it’s assuming two, but it hasn’t been confirmed yet. We also don’t know how the iPhone 5 will measure up to other phones in terms of performance. Apple hasn’t given any CPU speeds or GPU details..
