Confirmed: iPhone 5s has only 1GB RAM


Apple unveiled its highly anticipated 7th generation iPhone, the iPhone 5s at its media event last week.

iPhone 5s looks like the iPhone 5 but comes with major features such as the faster, and more powerful 64-bit A7 chip, vastly improved Camera system and the Touch ID fingerprint sensor.

As usual, Apple didn’t reveal how much RAM is included in the new iPhone. iPhone 5s’ tech specs webpage also doesn’t mention it.

There have been several speculations that it has 1GB RAM, but were waiting for the iPhone 5s to be disassembled to get a confirmation.

But it looks like we don’t have to wait as Anand Shimpi of AnandTech and John Gruber of Daring Fireball, who posted their iPhone 5s reviews, have confirmed that it comes with only 1GB RAM based on the benchmark tests.

Shimpi speculates that iPhone 5s comes with 1GB LPDDR3 RAM instead of LPDDR2 RAM used in iPhone 5c and iPhone 5 as A7 has a 64-bit memory interface (which has been confirmed by Apple). The LPDDR3 DRAM chips can shuffle information in and out 1,600 Mbps (compared to its 1,066 Mbps LPDDR2 predecessor), with up to 12.8 GB/s of bandwidth.

It also looks like based on the benchmark tests carried out by Shimpi, iPhone 5s is set to take back the crown as the world’s fastest smartphone. We’ll cover the benchmarks in a separate post shortly.

With iOS 7 features like smarter multitasking, we were hoping Apple will increase the RAM to 2GB. But looks like, it’ll happen we’ll have to wait another year. Are you disappointed that iPhone 5s has only 1GB RAM?
