With XSX it kind of feels like they would expect 10 GB for GPU and 3.5 GB for CPU. (Their GPU optimized™ RAM).Plus with SSD streaming, shouldn't that push most games towards using more RAM for CPU work? Traditionally a game might need 10gb for textures, models, frame buffers, and compute buffers but with super optimized streaming you'd just need a small amount of ram for the current textures and models on screen ala super textures. That means next gen games could use a smaller percentage of available memory for GPU tasks and a smaller percentage of that memory would scale with resolution.
A 75% GPU reduction would put it at 2.5GB plus 3.5GB for CPU work. With 1.5GB for flexibility.
The issue is, that's all very idealistic. It really puts a hard limit on what you can do with the CPU, even if you can scale all the GPU work.
At the moment it feels like a complete mistake to not have 12gb of ram instead of 10gb.
