GeForce RTX 5080 vs Radeon RX 9070 XT electricity cost
Compare the two GPUs under identical electricity-cost assumptions. Official rated graphics power is kept separate from the adjustable CPU and other-system load.
Same-assumption comparison
Compare electricity cost
This comparison intentionally applies the same utilization percentage, non-GPU system load, PSU efficiency, usage time and electricity rate to both GPUs. It is an electricity-cost model, not a performance benchmark. Real systems can differ because CPUs, board power limits, undervolting, workloads and PSU efficiency vary.

How to read this comparison
The default model applies 80% of each GPU's rated graphics power, 150 W for the rest of the PC, 90% PSU efficiency and four hours of gaming per day. Because those assumptions are identical for both cards, the modeled difference comes primarily from the graphics-power specification.
This does not mean one GPU will always draw exactly this much more power in real games. Board-partner limits, frame-rate caps, undervolting, CPU choice and the workload itself can move actual wall power substantially. Use the controls above if you have better assumptions for your own system.
Electricity cost is not a performance metric
A lower electricity bill does not tell you which GPU is faster or better value. PowerCostAtlas deliberately keeps this page focused on energy use and cost so that performance claims are not mixed into an electricity calculation.
