GPU vs NPU vs TPU: In-Depth Comparison of Three AI Accelerator Architectures — Which One Should You Use?
The AI accelerator chip space has three major mainstream architectures: GPU, NPU, and TPU. Add the recently emerging LPU (Language Processing Unit), and many developers find it hard to tell them apart.
This article compares them across four dimensions: architectural design philosophy, ecosystem maturity, real-world performance, and deployment cost.
