The headliner is the 4x efficiency increase from 2024-2026.

The HN headline comes from a section discussing 2030 projections:

> What Efficiency Gains are Expected? Based on a representative AI training workload, AMD projected rack-scale energy-efficiency gains are expected to produce one of two related benefits by 2030:

> Same compute, fewer resources: Approximately two 2030 AMD racks are expected to deliver the same compute as 570 racks in 2024, enabling a reduction in use-phase electricity by 20x and carbon intensity by 28x.

> More compute, same energy: Alternatively, efficiency gains are expected to enable 20x more compute, measured in floating point operations per second (FLOPs) per watt, using the same amount of energy.
