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).
