SNN Energy Efficiency Analysis

A rigorous measurement of whether a spiking neural network implementation actually delivers the energy savings it promises — and where the efficiency leaks are.

What It Is

Spiking neural networks are supposed to be dramatically more efficient than conventional deep learning. The biological proof exists: a human brain runs on 20 watts. But silicon implementations rarely achieve anything close to biological efficiency. This analysis measures exactly where the energy goes in a specific SNN deployment and identifies the gap between theoretical efficiency and measured reality.

We do not accept claims. We measure watts.

What You Get

Power breakdown — measured energy consumption per component: neurons, synapses, routing, memory access, I/O
Efficiency ratio — operations-per-watt compared to equivalent CNN/transformer on the same task
Biological comparison — how far the implementation is from the 20W brain benchmark, and why
Leakage inventory — where energy is wasted: static power, redundant spikes, memory thrashing, clock overhead
Optimization roadmap — ranked list of changes that would most improve energy efficiency
Workload sensitivity — how efficiency changes across sparse vs. dense activity patterns
