Running costs & efficiency (3-year electricity)
Over 3 years at 4h/day and $0.15/kWh, the RTX 5080 (360W) uses about $118 of electricity versus $189 for the RTX 5090 (575W) — roughly $71 less over the period for the RTX 5080. Enable the TCO toggle in the calculator to fold running costs into the value score.
Relative Value by scenario
Both products are normalized within the same in-stock market frame per preset — the two numbers compare directly. The lit pill = higher relative value in that scenario.
The same math, four ways
- 🏷️ Higher value, balanced weights — RTX 5080 (80 vs 57)
- ✨ Higher value for ray tracing — RTX 5090 (100 vs 70)
- 🤖 Higher value for AI / LLM — RTX 5090 (100 vs 64)
Each line is the same calculation under a different preset — not an editorial verdict. Snapshot 2026-07-15.
When each one makes sense
Pick the RTX 5080 when its scenario rows above lead and its current offer is at or below its 80+ target (balanced: $1246). Pick the RTX 5090 when its rows lead or its price falls below $2409. Feature ecosystems (upscaling, drivers, platform) are not in these numbers — weigh them separately.
