It was revealed during the San Francisco event last Wednesday that Apple’s A6 chip for iPhone 5 is likely to hold a 1GB RAM of processor. In fact, it doubles the amount found on both the iPhone 4 and iPhone 4S models.
In relation to this, the smartphone’s GeekBench results showed 1,601 points. This is way better than the iPhone 4S’s benchmark result of 629 and the new iPad’s score of 766. The score is based on the model with the device iPhone 5,2 ID. Simply put, Apple’s latest flagship mobile phone is 2.5 times faster than the iPhone 4S and twice as fast as the iPad 3.
Furthermore, it’s obvious that the iPhone 5 beats the best Android devices like the Samsung Galaxy S III. As posted on GeekBench, ASUS Nexus 7 gets the highest score of 1,598.
Meet iPhone 5’s A6 Chip
According to AnandTech, the unobscured parts numbers seen on the chip indicates a Samsung DRAM component. The component is said to sport a 1 GB or an addressable RAM.
The A6 chip carries part number K3PE7E700F-XGC2, which is a package-stacked DRAM module according to Samsung’s 2012 product guide. This component goes in line with Apple’s A-series SoCs to save space to implement package-on-package design. As posted on the website:
As always, the A6 features a PoP stack combining the SoC itself and its DRAM. The package-stacked DRAM helps save space, which comes at a premium inside a device as small as a smartphone. PoP stacks are quite common in all modern smartphones.
By breaking down the part number, the “K3P” hints a dual-channel LPDDR2 package with 32-bit channels. The “E7E7,” on the other hand, denotes the 512 MB density of each DRAM die that results to a total of 1 GB RAM. Lastly, the “C2” points to a 1,066 MHz cycle time/data rate.
Meanwhile, AnandTech notes that the new A6 chip can boost iPhone 5’s peak memory bandwidth by 33 percent compared to its predecessor. It can definitely feed the faster GPU and drive the higher resolution display.
What Lies Ahead for iPhone 5’s A6 Chip
Prior to this, there were claims that Apple’s new A6 processor for iPhone 5 could hold the company’s first custom-designed CPU. This component is a deviation from the previous A-series SoCs, which rely solely on ARM’s patented technology.
However, it is not just the memory clock that could have an impact on the handset’s memory bandwidth. Whether the A6 chip can also improve iPhone 5’s memory controller or not remains to be seen.
