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.

Both products are normalized within the same in-stock market frame per preset. A check marks the higher Relative Value; a difference of 3 points or less is shown as practically even.
Crossover price is loading. The switch-over point and Strong Value threshold appear as soon as today's offer snapshots are confirmed in your browser.

3-year electricity model
Over 3 years at 4h/day and $0.15/kWh, RX 7800 XT (270 W) adds about $89 in modeled electricity and RTX 4070 (200 W) about $66. The modeled difference is roughly $23. This uses rated power as a common comparison input, not a promise of wall-power consumption.

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.
08 · Alternative
A third option worth checking
The same scenario and market frame checks whether another currently priced model offers a cleaner trade-off.
Worth considering instead
RX 9060 XT — same S-tier capability for 1080p Gaming, about $267 cheaper · Value 96.
Neither of the two above is the only answer — this one clears the same bar for less. ⇄ Compare all three

09 · 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 7800 XT if…
- You can find it at or below its Strong Value threshold of $654 under balanced weights.
Choose B · RTX 4070 if…
- You prioritize AI / Local LLM, 3D Rendering, Light Use & Efficiency — it earns the higher capability tier in those tracked scenarios.
- Your priorities resemble AI / LLM — it has higher Relative Value under those presets at the snapshot offers.
- Lower rated power matters: 200 W versus 270 W for RX 7800 XT.
- You can find it at or below its Strong Value threshold of $645 under balanced weights.
10 · Methodology & FAQ
Read the methodology →How to read this comparison
The formula is a weighted geometric ratio. 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 7800 XT or RTX 4070?
- Under the balanced preset and the 2026-08-19 offer frame, they are practically even in Relative Value (74 vs 74). 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 4070 grades higher in 3 of 7 graded scenarios (4 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.
