Still a shame, because no sites actually cover it, for people wanting to do it the markets a minefield of gpus that have unknown performance at the task.

Only this week i saw someone who had bought a pair of 780s for v-ray rendering, when for the price of just one he could have gone with dual or tripple 580 sli depending on new/used prices.

There is at least a few sites that DO cover compute benchmarks and in your particular case the ones dealing with light transport simulation ... 

As for mining performance, everything prior to Maxwell on Nvidia's side sucks badly because of bad integer or memory subsystem performance ... 

AMD hardware has a good history on mining performance and the hashing benchmarks show for it too ...

All of that is in the past now since FPGA's and ASIC's are threatening GPU mining in general ...

Luxmark isnt representitive, (AT ALL) of v-ray render performance, and does the exact opposite in terms of informing budding 3d designers at which hardware is best for actual 3d modelling and rendering by providing results that are virtually the polar opposite of what they will get in actual 3d modelling applications, not just broadly generic benchmark testing.

Why you brought up gpu mining I cannot for the life of me fathom.
