8GB GDDR5 UNIFIED memory. This is the only RAM that is available to PS4 and is shared by eveything.(This is a positive thing in case you don't understand)

Yeah, got that from a previous post. I'm curious to see how the 8GB will be split up for high resource games, like how it will prioritize the lion's share of RAM in a scene with a ton of particle systems going, LOD, mutiple character models, physics, and everything else. There has to be some sort of pecking order as to who gets first dibs to the RAM resources.

I also would like to chime in that I am not so sure how possitive having only GDDR memory for all parts of the system is a good thing.  Latency will be an issue for pieces of the hardware that only work on a small bit of memory very fast compared to have a faster bandwidth.  It will be interesting to see how Sony and AMD have solved the latency issues or if they just compromised.  It could be that bandwidth was more important for overall game performance then CPU latency.
