02 · Decision matrix
One decision, three separate questions
Capability ignores price. Relative Value adds the current dataset offers and your priorities. Keeping them separate prevents a cheap product from being mistaken for the faster product.

3-year electricity model
Over 3 years at 4h/day and $0.15/kWh, RX 7900 XTX (420 W) adds about $138 in modeled electricity and RTX 5080 (360 W) about $118. The modeled difference is roughly $20. This uses rated power as a common comparison input, not a promise of wall-power consumption.

08 · Customize
Try other models and your own priorities
Presets are starting points. Swap either side, then open Advanced weights only if you want to tune the formula directly.
09 · Alternative
A third option worth checking
The same scenario and market frame checks whether another currently priced model offers a cleaner trade-off.
No cleaner third option in this dataset
The scenario-aware check did not find a currently priced alternative that improves this decision without changing the trade-off. This is a dataset result, not a claim that no other product exists.
10 · Decision guide
Choose based on the trade-off you actually want
These are evidence-linked conditions, not universal buying verdicts. Feature ecosystems, software support and platform preferences remain your call.
Choose A · RX 7900 XTX if…
- You can find it at or below its Strong Value threshold of $1152 under balanced weights.
Choose B · RTX 5080 if…
- You prioritize 4K / VR, Ray Tracing, AI / Local LLM — it earns the higher capability tier in those tracked scenarios.
- Your priorities resemble 4K Ultra / VR, Ray Tracing (1440p), AI / LLM — it has higher Relative Value under those presets at the snapshot offers.
- Lower rated power matters: 360 W versus 420 W for RX 7900 XTX.
- You can find it at or below its Strong Value threshold of $1331 under balanced weights.
11 · Methodology & FAQ
Read the methodology →How to read this comparison
The formula is a linear weighted sum inside the current comparison frame. Capability, price and user priorities stay visible as separate inputs so the result can be challenged and changed.
- Which is better value right now: RX 7900 XTX or RTX 5080?
- Under the balanced preset and the 2026-09-11 offer frame, they are practically even in Relative Value (72 vs 72). Change the preset or weights to reflect your own priorities; capability is a separate question, answered by the tier table.
- Which one is more capable, ignoring price?
- RTX 5080 grades higher in 4 of 7 graded scenarios (3 tied) and is never graded lower.
- Where can I compare current offers for both?
- Dated offer snapshots for both models are listed on their product pages (linked above); the interactive calculator recalculates both with your own weights and budget.
