Fig. 2: Comparison of carbon components.
a ECF (Embodied Carbon Footprint) and b OCF (Operational Carbon Footprint) per inference for the reported DNN models of LT (Lightening-Transformer, electro-photonic) and A100 (electronic) accelerators23. LT emits less ECF and OCF than A100. The breakdown of LT's ECF is shown. CMOS components contribute to the dominant portion of LT's ECF.
