I’ll try when I get home

what’s are the benefit over the official benchs?

There’s an official Cycle benchmarks for multiple GPU? It’s a good reference for people who are interested in getting a new card while keeping the old one. Personally, I’d like to see benchmark for GTX 1080 + GTX 1070 cause I’m thinking about replace my GTX 660 Ti with GTX 1080.

Thinking of getting 2 Vega 64. Anyone has benchmarks for that?

Here is my rundown with 4 RX 480s

dual vega 64 here. First test with no tweaks of any kind on 2.79 offical. With kernal loads: 2.15. Second rendering: 1.11

… and on latest buildbot (15 november) I got 52 s on the dual vega 64.

Nice! Any one with dual 1070s or dual 1080s wanna post the bench?
