NVIDIA has released the Titan Xp which is an update to the Titan X Pascal (they both use the Pascal GPU core). They also recently released the GTX1080Ti which proved to be every bit as good at the Titan X Pascal but at a much lower price. The new Titan Xp does offer better performance and is currently their fastest GeForce card. How much faster? I decided to find out by running a large Deep Learning image classification job to see how it performs for GPU accelerated Machine Learning.
A few weeks ago I wrote a blog post titled Should You Learn to Program with Python. If you read that and decided the answer is yes then this post is for you.
How good is the NVIDIA GTX 1080Ti for CUDA accelerated Machine Learning workloads? About the same as the TitanX! I ran a Deep Neural Network training calculation on a million image dataset using both the new GTX 1080Ti and a Titan X Pascal GPU and got very similar runtimes.
The short answer to that question is, yes. If you want to know why you would want to do that then read on.
Does PCIe X16 give better performance than X8 for training models with Caffe when using cuDNN? Yes, but not by much!
NVIDIA’s Pascal GPU’s have twice the computational performance of the last generation. A great use for this compute capability is for training deep neural networks. We have tested NVIDIA DIGITS 4 with Caffe on 1 to 4 Titan X and GTX 1070 cards. Training was for classification of a million image data set from ImageNet. Read on to see how it went.
If you are happy to use Ubuntu 14.04 LTS (Ubuntu-MATE in our case) then setting up a system with the NVIDIA DIGITS software stack is simple. I’ll give you some guidance on getting everything working, from the Linux install to the DIGITS web interface.
Machine Learning is getting a lot of attention these days and with good reason. There are mountains of data to work with and computing resources to handle the problems are easily attainable. Even a single GPU accelerated workstation is capable of serious work.
