It has 8GB of memory. It is DDR5. Yes, it is shared. It's the same as the PS4 devkits.
Its GDDR5

DDR5 only exists in very small quantities. GDDR5 is more common. DDR5 in 8gb quantity (to my knowledge) does not exist. So PS4 has DDR3, didn't mean to troll.
Why does it have to all be on one stick? The PS4 straight-up doesn’t have DDR3 RAM, unless they’re blatantly lying about a very specific and trivially disproven detail.
I don’t get what your angle is here.
Yeah, I'm not sure what it all being on one stick has to do with anything, here. My current cards have 4gb DDR5. The newest NVIDIA cards (or is it ATI?) have 6gb. I don't see 8gb as being unrealistic. Also, of course it's shared between system and VRAM. Didn't we all assume that would be the case?
This is why PS4 can give PCs a run for our money for a bit, too. PCs are still bogged down by the fucking 4gb RAM/VRAM target with (generally) lower resolution textures than we could have. Maybe this will wake us up and we'll quick-step it a bit.
It's an APU. Shared CPU and GPU in one chip. I could be wrong, but I doubt that there would be 8GB of VRAM. Hell I doubt that they would use 4GB.
I think Salad10203 is right it's not DDR5 i'm sure its GDDR5. Which is alot more readily available.
That's quite an understatement, because I'm pretty sure DDR5 doesn't exist yet and DDR4 is just hitting production. :) -- So, I assumed we were all referencing GDDR5 as there isn't anything to differentiate it from at the moment (I don't even know if there is a spec for DDR5, yet?).
GPU memory and system memory are different beasts, but these are custom-purposed systems and I suspect that the engineering and materials needed to provide separate system and GPU memory exceeded the expense of just using GDDR5 for both with negligible systems impact. It would be a far better option than going the other way around (all DDR3, with some dedicated for the GPU).
Anyway, the point is that there is one type of memory. There is 8gb of it. It services both the system and the video, which is what the original poster was saying wasn't going to be the case.
