@radikel Unified pool just means that everything in the system shares the same memory address space, rather than the CPU having its own set of memory and the GPU having its own set of memory. It makes things a lot more flexible for developers with how they want to use the memory.
Not sure how much more bandwidth it has - you'd have to know more than just the type of memory to answer that and I don't feel like looking it all up (assuming Sony has even released enough relevant details about clocks etc for the memory which I doubt)
@Double-Ego lol you can do whatever you want I just think it's funny that you have at various times in this discussion tricked yourself into thinking that you are "objective" and/or that you are only "stating facts"
@radikel 8GB GDDR5 is a magic wand that turns an otherwise extremely mediocre computer into a super computer and means you need to go give Sony your money for this console RIGHT NOW
In all seriousness, PS4 is just using a unified memory pool and they happened to choose GDDR5. It's a bit higher latency than DDR3 but it's got a lot more bandwidth.
@Double-Ego Not underestimating... just estimating based on what we know now and refusing to make estimations based on hypothetical future optimizations.
