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, RTX 4090 (450 W) adds about $148 in modeled electricity and RTX 5090 (575 W) about $189. The modeled difference is roughly $41. 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.

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 · RTX 4090 if…

  • Lower rated power matters: 450 W versus 575 W for RTX 5090.
  • You can find it at or below its Strong Value threshold of $1537 under balanced weights.

Choose B · RTX 5090 if…

  • You prioritize Ray Tracing — it earns the higher capability tier in those tracked scenarios.
  • Your priorities resemble Balanced, 1440p Sweet Spot, 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 $2369 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: RTX 4090 or RTX 5090?
Under the balanced preset and the 2026-09-11 offer frame, RTX 5090 has higher Relative Value under this configuration (51 vs 43). Value is price-dependent and moves with your weighting; capability is a separate question, answered by the tier table.
Which one is more capable, ignoring price?
RTX 5090 grades higher in 1 of 7 graded scenarios (6 tied) and is never graded lower.
At what price does the RTX 4090 become the better value?
Holding the RTX 5090 offer dated in the 2026-09-11 frame fixed, the calculation flips in favour of the RTX 4090 at roughly $2919 or below (balanced preset). Not a price forecast.
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.
