I am new on the forum and I would like some advice about what GPU is the best option for my research. I am working on Computer Vision, more specifically, on Deep Convolutional Neural Networks. I use Caffe library and large datasets of images.
Because of that, I would need a GPU with enough memory to deal with high resolution images. My first option was the Titan X Pascal, however, I found that Tesla K40 and Tesla K80 are also good at deep learning.
I am sure about choosing Titan X opposite Tesla K40. However, it would be interesting for me to try the multi-GPU usage of Caffe. So my question is, what would be better? Two Titan X or one Tesla K80? I don’t know much about the hardware details of connecting 2 GPUs, so I ask.
Thank you for your help.
