Table 12. Rendering times for the RED project.
Since most RED producers are probably on dual-CPU workstations, I tested preview on the Z600 using the Quadro 4000 card with playback resolution set to 1/4 and Use Maximum Render Quality not enabled for preview. Table 12 shows the results, which were better with the GPU, though not dramatically so.
Table 11. Preview performance for the RED project.
From this particular RED-based project, it appears that CUDA acceleration is definitely a plus for rendering RED-based projects, though performance did not appear to scale with the card as the $423 Quadro 2000 performed similarly to the $1,700 Quadro 5000. If you’re producing RED source footage, you should prioritize CPU cores over GPU cores
, and buy a dual-CPU workstation rather than the most expensive graphics card.
