Finally I found.
"The UE4 demo is running on PC, specifically an Intel Core i7 processor with an NVIDIA GTX680 and 16GB of RAM - what Epic terms a standard development box."
Of couse the Demo not used all these 16GB RAM but I think it used more than 4GB VRAM + System RAM combined... the Epic DevMachine have the same amount of RAM present in the new DevKit for PS4.
