Provide proof please. I had a 5s on iOS 8 and 9 and I never noticed any difference compared to a 6 plus. the ram does make the biggest difference.

Proof? Maybe you don't notice the fine things, but every single iPhone I've had has slowed down noticeably after updating to the following OS, and dramatically after the second. The animations get choppier, things start to take longer to happen (multi task comes up slower, etc). The proof of that can be seen in youtube videos (comparison's etc.), if you really want to try and locate the specifics.
Other than that, the benchmarks which
@timeconsumer provided here also demonstrate the lower power which older devices have compared to newer ones. If the devices are running the same exact software, on different hardware, then by your opinion they should run exactly the same - but they don't. If you would like to say that old devices don't get slowed down quite as much because of equivalent RAM, then by that same thought process the iPhone 5 should be doing just fine on iOS 9 as well, but it's not. It can barely run iOS 8 (imo) even though it also has 1GB of RAM.
I don't need to work for apple to know simple cause and effect.

I do plan on buying the iPhone 7 once it's released.
Awesome, I think it's going to be a great upgrade, especially if they bring out the Deep Blue color
