GPU (Graphics Processing Unit) vs NPU (Neural Processing Unit)

Key Comparisons:

  • Purpose: GPUs are general-purpose parallel processors; NPUs are specialized for AI/machine learning.
  • Efficiency: NPUs consume much less power (single-digit watts) compared to GPUs, making them ideal for battery-operated devices
  • Workload: GPUs excel at training AI models and rendering graphics; NPUs excel at inference (running models).
  • Design: GPUs have thousands of small, programmable cores; NPUs feature optimized memory hierarchies and matrix multiplication units.

NPU’s are energy efficient and time deterministic!
