Not really. It shows that it makes memory usage much more constricted when you only have 4.5-5.5 shared RAM.

Well of course it does.  More constricted wasn't what you were saying though.  More restricted is a no brainer, that is like saying a 5.5 inch pizza is smaller than an 8 inch pizza and a 3 inch pizza. 

Using those pizzas for a metaphor though. The advantage of sharing, is that you can take 4 inches of the pizza whereas in the second part you may be restricted to 3 inches.  So, sharing allows it to have more.  

Now you followed this up with they both need to be about the same.  

"The CPU will in almost all cases be needing just as much RAM as the GPU"

And yet you and I were both able to pull up examples of this not being true.  

My point then was to show that the CPU needs a lot RAM as well, not just the GPU. To clarify, the CPU usually needs just as much RAM, if not more, than the GPU.

Games like Killzone, which put all resources into looking as pretty as possible, will be heavier on the GPU, but most games that come out will be more than just showpieces. Those games will have much more difficulty optimizing for memory.
