I don’t mean to sound arrogant but I have a lot of experience in scene optimization and I can count how many of my scenes couldn’t fit in the GPU.

Planning would let you know in advance what will be near to the camera and what won’t be so you would know where the detail needs to be and if camera angles change have different level versions of the model on other layers. Yet in the current chosen camera angle the desk items account for less than 5% of the shot. Not to criticize the scene but just as an example, the classroom in these benchmarks has so much detail on the desk you could do a full HD close up render of it. Add to the fact that Blender now pretty much allows keyframing any setting means that subsurf levels can be animated according to the distance of the objects, or decimate modifiers etc. I have however built many scenes with a fair level of complexity and they rendered just fine on my old Gtx 570, and that was a 1gb card. Same, or slightly longer with the exception of ‘koro’ where the gains made by setting the tile size to 160*120 seemed to disappear.

Maybe other .blend files should be added?ĬPU: Intel Xeon W-2145 8 Cores, 16 Threads 3.7GHz That confirms our own experience that fast GPU is great for previewing and lighting work, and fast CPU is great for the production rendering. When shots get more complex, CPUs win the performance battle.

Most strikingly so-far is that the performance of CPUs is in a similar range as GPUs, especially when compared to costs of hardware. We aim at updating it regularly, also when new hardware comes in – and especially when render features improve in Cycles.

The goal is to have an overview of systems that are used or tested by developers of Cycles. On the links below you can inspect the spreadsheet with results, and load the. Blender Institute prepared six Blender files for testing Cycles rendering with CPU/GPU, using various settings and design styles but based on actual production setups.
