Well yeah you have 4gb of vram more, but when it comes to cuda cores and mem bandwith and speed the desktop version has a lot more kick. 

A little more not a lot. OTOH opened 4 views each a separate room from Grandview-set all to PBR, 50 lights, improve lighting, raytrace shadows, reflections, ray cast shadows.

GPU pegs at 100 for a second or two, video engine is 0, and max on bus interface is 15 BUT video memory hits 85% with 4 open, added in one standard view and it's at 95% and that doesn't drop even after the GPU goes to rest. .Those are on a 2560 display, would guess 4K needs more. -no lag navigating the views.

 

There's a thread back last year when PBR came out where a lot of folks ran tests (I think it was in Q & A?)  Everyone's GPU pegged to 100% during initial loading as far as I remember. (most CPUs cranked up a bit at first too) Those were all static, no one dealt with walk throughs (I don't use em)
