Redshift on a mac Feb. 5, 2018, 3:03 p.m.

Just as an update I've now connected a second 1080 TI to my Late 2013 Mac Pro setup. Configuring it was surprisingly difficult and took almost a full day but now it works well. Living life on the edge. My render speed is almost 2x as fast with two cards. Benchmark scene went from 12 minutes on one card to 6:20 with two.

The thing the 4x PCIe speed might limit is the speed geo and textures load into the cards memory. Typically scenes load into in the ipr quite fast and the render goes from loading to rendering as quickly as mantra.

The Nvidia drivers are less mature for the Mac than the other platforms and there’s no way to overclock currently. so I’m getting slightly slower speeds than an equivalent PC, but not by much.

@matleaf – About two weeks into owning an eGPU and my experience has been… awesome! I went with a sonnet eGPU enclosure and a 1080 ti graphics card connected using a thunderbolt 2 to 3 converter. I also purchased a redshift license.

Getting the mac to recognize the GPU was difficult and involved terminal scripts – not plug and play at all (Apple is supposedly fixing this). However once up and running its absolutely smashing through renders.

Many jobs are 20-30x faster. Things like GI and volumetric lighting used to be too time-consuming to consider, I now just shrug. Best purchase I've made in years. Highly recommend. I will buy a second eGPU and card in the coming months to double speeds yet again. Even After Effects now runs faster (I set it to use CUDA in preferences).

Finally, by freeing up the CPU I'm able double the speed of certain tasks. For example I've been able to simulate pyro while simultaneously rendering the previous frame. For example, a frame that takes 4 minutes to simulate and 4 minutes to render will now take a total of 4 minutes to do both by splitting across the CPU's and the GPU, rather than 8 minutes if both were on CPU. Hopefully that makes sense.
