PROBLEM
What it had to solve.
Quantization papers report accuracy on single devices. In practice, the "best" method changes with the hardware — memory bandwidth, tensor cores, and INT support all shift the tradeoff.
Cross-hardware benchmarking of AWQ, GPTQ, and SmoothQuant across NVIDIA A100, Jetson Orin, and Raspberry Pi. Derived device-specific deployment strategies for edge and cloud.

Quantization papers report accuracy on single devices. In practice, the "best" method changes with the hardware — memory bandwidth, tensor cores, and INT support all shift the tradeoff.
A unified harness runs each method on each device across six models, logging latency, memory, and downstream accuracy. Results are mapped onto a decision matrix that picks the right method for a target device + model size.
AWQ dominated on Orin for 7B-class models; SmoothQuant won on A100 for throughput; GPTQ remained competitive on CPU. All three held within 1% of FP16 accuracy on downstream tasks.
