Chances are you’ve heard about Apple’s A7 chip and how it’s the first 64-bit mobile processor. Many people, myself included, wondered why Apple would switch to 64-bit when all their iOS devices still use just 1 GB of RAM. I mean, ask and geek wearing glasses why someone would build a 64-bit processor, and the first bullet point he’ll likely list will be the ability to address 4 GB or more of RAM.
Turns out this isn’t the case. ARM’s new 64-bit architecture is as much about performance improvements as it is about increases a processor’s address space, yet both NVIDIA and Qualcomm were at CES showing off reference hardware with 4 GB of RAM, despite the fact that they both had 32-bit processors. According to MobileGeeks, the Snapdragon 805 reference tablet that was being shown to the press had 4 GB of RAM. And according to an analyst note by Jon Peddie Research, the Tegra K1 reference tablets that were shown off at CES were of the 32-bit variety, yet they too had 4 GB of RAM inside.
But let’s not ignore the elephant in the room, Android itself isn’t 64-bit optimized. While we’ll likely hear an announcement about this later this year, it’s not like Samsung or anyone else can launch a 64-bit chip, slap Android on it, and have it take advantage of all that chip’s processing power. So right now us Android fans are basically stuck waiting for the Big G to push out Android 5.0 Lemonade or whatever it’ll end up being called.
That being said, if the Galaxy S5 has 4 GB of RAM, I wouldn’t be surprised.
