Or they clocked the cpu and gpu a bit higher and fixed.It needs more ram because of the resolution. The iPhone 6 will outperform the plus across the board in real world use as they both use the same processor. I am wagering that the plus will be plagued with stutters and slowdowns to some extent which won't be present in the 4.7.

To be honest, why should you care about available ram?
It's a great addition for computers, but having owned the 5S and every phone before it. Other than just having more ram, I've never been in a situation where I felt "wow, I'm stuck. wish I had more ram."
I'm not trying to be funny. I just have yet to come across a situation where there was tasks or applications running that pushed my device to it's limits. processor or ram.
1080p screen. This sucks alot of ram. 64bit too. So there is enough left for one browser tab. The second will be closed. Thats how bad its going to be.
