Why Android and Windows Phone Devices DO Need More RAM!

I'm pretty sure this conversation will be familiar to most of you.
You: "My new XYZ phone/tablet has 2 gigs of RAM. How much does your iPhone/iPad have?"
Random friend: "What are you going to do with 2 gigs of RAM on your mobile device?"
And then, no matter how much you try to explain them, they just sit there, understanding nothing, like typical Apple users.

Well, now you have an answer.

Most of the Android and Windows Phone devices come with 1080p (1920x1080) displays and 2 GB RAM nowadays. But, some phones like Vivo Xplay 3S, LG G3 and Oppo Find 7 come with 2K (2560x1440) displays. You don't have to be a rocket scientist to make this deduction that all phones with 2K displays come with 3 GB RAM. Do you see where I'm going with this?

More pixels means more RAM required by the GPU. The Nexus 10 was announced in 2012 and was pretty much the first mobile device to feature a resolution of 2560x1440. I remember being disappointed that the Google event was cancelled due to Hurricane Sandy but just watching the specs of the Nexus 10 more than made up for it! It boasted of a Cortex-A15 dual core processor, 2 GB RAM and a 2K display. Those specs rock even today!

When I first booted my Nexus 10, I was surprised that it showed a total of only 1.5 GB RAM. After the 4.2.2 OTA update, it went down to 1.1 GB! I was mad. But, then I read somewhere on XDA that the GPU requires DEDICATED 900 MB of RAM for the enormous resolution.

The iPhone 5S has a resolution of 1136x640 and 1 GB DDR2 RAM. Less pixels on iPhone means less RAM required. It also has a little to do with the manufacturer bloat of Android devices but I am considering only stock Android/Google Play Edition devices here.

And this is the exact same reason why the Moto G and Moto E can run smoothly with 1 GB RAM. I hope now you understand why Android phones need more RAM and can shut your iCrap friends as well! :P
