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.

Fit, compatibility and ownership context

Only verified structured fields are shown. Physical fit, connectors, cooling and typical warranty belong to the representative tracked partner card named in each column; other board variants can differ.

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.

“Not tracked” means the source data does not contain a verified value; no default or guessed specification is substituted.

07 · 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.

08 · Alternative

A third option worth checking

The same scenario and market frame checks whether another currently priced model offers a cleaner trade-off.

A price-aware third suggestion appears once today's offer snapshots are confirmed in your browser.
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 B · RTX 4070 if…

  • You prioritize AI / Local LLM, 3D Rendering, Light Use & Efficiency — it earns the higher capability tier in those tracked scenarios.
  • Lower rated power matters: 200 W versus 270 W for RX 7800 XT.

10 · Methodology & FAQ

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.

Read the methodology →
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.
