ROI Calculation Logic

Assumes a 20% reduction in annual memory power consumption and a 50% reduction in device replacement frequency for data centers. For a large data center (assuming annual power costs of ~$66.5M (AI est.) and device replacement costs of ~$1.5M (AI est.)), the projected annual savings could be (~$66.5M × 20%) + (~$1.5M × 50%) = ~$14M (AI est.). This suggests the technology could significantly reduce power and maintenance costs.
