Imagine 8GB 3D V-cache. That would be glorious.

What use cases would this be good for?

PCIe rebar currently uses system RAM to VRAM communication. 3dvcache to VRAM via DMA could be made possible without even accessing RAM, this would completely eliminate 50+ ns of RAM access latency (of course the necessary data needs to be already available in 3dvcache from system RAM before any of this fancy stuff happens).
