Optimizing Vision Transformers on Edge Hardware with NVIDIA TensorRT
Deploying high-parameter Vision Transformers (ViTs) to edge embedded devices requires aggressive latency optimization without degrading semantic accuracy. In this deep dive, we benchmark INT8 post-training quantization and kernel fusion techniques that yield up to 4.2× throughput improvements on NVIDIA Jetson Orin compute modules. We demonstrate how combining structured pruning with TensorRT engine compilation enables real-time sub-15ms multi-stream inference for high-speed industrial robotics and automated inspection pipelines.
