High Expectations

A couple of years ago, a new restaurant opened for business in town. For anyone traveling into St. George from Las Vegas or Zion National Park, it is hard to miss because it’s situated the ledge which overlooks the town.

RTX 2080Ti with NVLINK – TensorFlow Performance (Includes Comparison with GTX 1080Ti, RTX 2070, 2080, 2080Ti and Titan V)

More Machine Learning testing with TensorFlow on the NVIDIA RTX GPU’s. This post adds dual RTX 2080 Ti with NVLINK and the RTX 2070 along with the other testing I’ve recently done. Performance in TensorFlow with 2 RTX 2080 Ti’s is very good! Also, the NVLINK bridge with 2 RTX 2080 Ti’s gives a bidirectional bandwidth of nearly 100 GB/sec!

How to Enable and Test NVIDIA NVLink on Quadro and GeForce RTX Cards in Windows 10

NVLink is enabled in different ways depending on what video cards you have, so we have compiled instructions for multiple GeForce and Quadro models. Once you’ve gone through those steps, though, it can be helpful to have a quick way to test and make sure it is working. We have put together a small program that does just that – and reports which video cards in a system are connected via NVLink as well as how much bandwidth they have between them.
