Nvidia has released a new version of TensorRT, a runtime system for serving inferences using deep learning models through Nvidia’s own GPUs.

Inferences, or predictions made from a trained model, can be served from either CPUs or GPUs. Serving inferences from GPUs is part of Nvidia’s strategy to get greater adoption of its processors, countering what AMD is doing to break Nvidia’s stranglehold on the machine learning GPU market.

Nvidia claims the GPU-based TensorRT is better across the board for inferencing than CPU-only approaches. One of Nvidia’s proffered benchmarks, the AlexNet image classification test under the Caffe framework, claims TensorRT to be 42 times faster than a CPU-only version of the same test—16,041 images per second versus 374—when run on Nvidia’s Tesla P40 processor. Though often, industry benchmarks should be taken with a grain of salt.

Serving predictions from a GPU is also more power-efficient and delivers results with lower latency, Nvidia claims.

TensorRT does not work with anything other than Nvidia’s own GPU line-up, and is a proprietary, closed-source offering.

AMD, by contrast, has been promising a more open-ended approach to how its GPUs can be used for machine learning applications, by way of the ROCm open source hardware-independent library for accelerating machine learning.
