Pc GPU's use GDDR5, regular memory is usually just DDR3 though.
Does anyone know how the Nextbox is going to work though? Is it using an APU with unified memory like the PS4?
When we talk about just RAM, Or RAM as in a whole, we are hinting the System RAM.
On PC the SYSTEM RAM is DDR3, On the PS4 it's GDDR5, PC's Graphics Cards have been using GDDR5 since the origin of HD 4xxx Series.
Going by the rumours, it's the same architecture as the PS4, A TRUE Heterogeneous System Architecture (AMD are still making their own HSA APU for the PC so Sony went ahead and made their own HSA solution now i.e. PS4)
Yes the system will have unified memory regardless of what type of memory they implement anyway (That would help in faster texture processing).
I really hope it's not DDR3.
There is a reason why PCs haven't been using GDDR5 RAM as their system RAM, GDDR5 RAM (Which is just modified DDR3 RAM) is specifically made for GPUs that have higher bandwidth, if MS chose to have DDR3 RAM for the NextBox, the memory would have no advantages for the GPU, also it would be ironic to have DDR3 as RAM when you're going to have a HSA system.
