CUDA Performance
CUDA Rendering
Since CUDA is a proprietary Nvidia technology, the Radeon HD 7970 GHz has to sit out the following four benchmarks. Despite its provenance as a GK110-based card, the GeForce GTX 780 always comes in behind the older 580 when it comes to pure rendering. The Octane benchmark is the sole exception. Meanwhile, the pricier Titan clearly dominates the field, while the GeForce GTX 680 finds itself relegated to last place just as consistently.
