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.

03 · Price crossover

The price changes the answer

Current offers, crossover points and Strong Value thresholds answer different questions. Thresholds are calculations, not price forecasts.

3-year electricity model

Over 3 years at 4h/day and $0.15/kWh, RX 7800 XT (263 W) adds about $86 in modeled electricity and RTX 4070 (200 W) about $66. 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.

Worth considering instead
RX 6900 XT — same S-tier capability for 1080p Gaming, about $158 cheaper · Value 70.
Neither of the two above is the only answer — this one clears the same bar for less. ⇄ Compare all three
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 7800 XT if…

  • Your priorities resemble 4K Ultra / VR — it has higher Relative Value under those presets at the snapshot offers.
  • You can find it at or below its Strong Value threshold of $649 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 Ray Tracing (1440p), AI / LLM — it has higher Relative Value under those presets at the snapshot offers.
  • Lower rated power matters: 200 W versus 263 W for RX 7800 XT.
  • You can find it at or below its Strong Value threshold of $621 under balanced weights.

11 · Methodology & FAQ

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.

Read the methodology →
Which is better value right now: RX 7800 XT or RTX 4070?
Under the balanced preset and the 2026-09-11 offer frame, they are practically even in Relative Value (72 vs 69). 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.
