While this may be slightly off-topic, this question does pertain to data science and machine learning. I want to train a VGG16 model on Imagenet from scratch. For this purpose, I am looking into either buying four to six GTX 1080 Ti's or one Tesla V100. I have a feeling that four GTX 1080 Ti's will perform far better than a single V100, but has there been any practical research into this?
EDIT - Each GTX 1080 Ti has 11.3 teraflops of FP32 performance (or 45.2 teraflops for four 1080 Ti's, or slightly less since the scaling isn't linear), whereas the V100 is 100 teraflops, or more than double the performance of four GTX 1080 Ti's. Anyone have any benchmarks for these two on imagenet performance?
