GREEN RESTAURANT BENCHES if you want it i can share the file in PM (win10 on 2.8 only)
ORIGINAL RENDER BELOW
E CYCLES RENDER BELOW
Cycles 1x 2080ti (64x64) ------------------------------> 30.48 min
E-Cycl 1x 2080ti (Auto-tiles)--------------------------> 19.30 min = 1.57x Faster than master
Cycles 1x 1080ti (64x64) ------------------------------> 40.03 min
Cycles 1x 1080ti vs 1x 2080ti > = 2080ti is 1,3x Faster
E-Cycl 1x 1080ti (Auto-tiles)--------------------------> 25.34 min = 1.57x Faster than master
E-Cycl 1080ti vs 2080ti > = 1080ti in E-cycle is 1,2x Faster than a 2080ti in master
Cycles 2x 2080ti (64x64) SLI ENABLED ------------> 15.43 min
Cycles Scaling compared to a Solo card > = 1.97x Faster
E-Cycl 2x 2080ti (64x64) SLI ENABLED ------------> 11.03 min = 1.39x Faster
E-Cyc Scaling compared to a Solo card > = 1.74x Faster
this mean that i could got to 9.82 if the scaling was the same with two cards
please ?
SLI DISABLED OR NOT, IS THERE AN IMPACT ON THE RTX CARDS ?
Cycles 2x 2080ti (64x64) SLI DISABLED ---------> 15.30 = 1.5% faster
E-Cycl 2x 2080ti (64x64) SLI DISABLED ----------> 11.00 = 0.3% faster
as you can see, with the rtx series sli disabled or not the changes are not representative
Not with the RTX series, they use a new NV-link and this rules don’t apply with thoses cards visibly

this new Nvlink connector can also share vram, so if the devs optimize the set up i could have up to 22Gb of vram…
HAVING A WINDOWS MINIMIZED COULD AFFECT RENDER ?
E-cycl 2x 2080ti + WINDOWS MINIMIZED = 10.15 = 1.07x Faster than an active windows
so yes
IMPACT OF A COMMANDLINE RENDER ?
i got 10.37 with a command line render, still faster
also the VRAM went from 4500Mo to 3200Mo so the UI take 1.3Go of VRAM
