# Energy Efficiency Analysis on Neural Network Operations and Components Suite Source: [Energy Efficiency Analysis on Neural Network Operations and Components Suite]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:42:02.138Z Evaluation of the energy efficiency and operational characteristics (spikes, neuron activity) of neural network components, often comparing different hardware platforms (e.g., Loihi vs GPU). A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Energy Efficiency Analysis | | Dataset (including any stated split) | Neural Network Operations and Components Suite | | Metric | Energy (nJ) - Loihi | | Unit | OTHER | | Direction | Lower is better | | Results loaded | 33 of 33 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [Energy (nJ) - Loihi](): Lower is better; unit: OTHER. - [Energy (nJ) - GPU](): Lower is better; unit: OTHER. - [Energy Savings Ratio](): Higher is better; unit: SCALAR. - [IF Neuron Count](): Lower is better; unit: SCALAR. - [Active Spike Count](): Lower is better; unit: SCALAR. ## Recorded results | Method | Energy (nJ) - Loihi | Result date | Report paper | | --- | --- | --- | --- | | NEXUS | 0.0004 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.012 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.024 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.04 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.048 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.059 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.059 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.068 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.073 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.081 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.084 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.1 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.105 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.12 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.129 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.132 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.146 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.147 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.153 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 0.179 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 3.09 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 22.4 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 49.6 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 49.6 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 49.6 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 56.6 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 149 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 198 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 198 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 198 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 328 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 396 | Not recorded | 697c3af7a8b01e76cc8da3ea | | NEXUS | 724 | Not recorded | 697c3af7a8b01e76cc8da3ea | ### NEXUS Energy (nJ) - Loihi: 0.0004.
