I doubt SDD will be used as VRAM on PS5, but developers will be able to stream data much faster, and therefore save big amount of VRAM.
You are correct, they won't be using flash in the same was as main ram / vram. It's a great way to access data though, as you say, reducing the amount of assets you need in memory ahead of time.
They've used ssd as vram before Google SSG solid state graphics, its a GPU tech from AMD, the same people designing consoles for Sony and Microsoft, and they showed it rendering a frame of 200+ billion polygons in realtime and it's not a procedural shader trick like Nvidia showed recently,
basically the ssd on next gen consoles doesnt work like your usual pc ssd it's simply the ssd soldered close to the gpu and the GPU can access it directly without consulting the CPU or other silly interfaces it dramatically reduces latency!
More memory means big things for visual computing.www.pcgamer.com
They aren't using it interchangeably with the dram. They are using it to access or create very large data sets.
Video ram has to be able to sustain a practically unlimited number of read / write operations and at very, very high bandwidth.
The flash memory on these Radeon cards cannot do that, and no-one would attempt to use it in the same manner as the 8 or 16 GB of dram on the card.
Flash doesn't have the endurance or bandwidth to act as a direct substitute for video ram, and it will not be used for that in next gen consoles.
You are badly misleading people.
