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.

RTX 5080 grades higher in 2 of 6 graded scenarios (4 tied) and is never graded lower. 1 scenario can't be graded for one of them (shown as N/A). These are the same S–F grades as the tier list — capability only, price excluded. The value rows below add prices from the 2026-09-27 offer frame. How tiers are assigned →

3-year electricity model
Over 3 years at 4h/day and CAD 0.18/kWh, RTX 4080 Super (320 W) adds about CAD 126 in modeled electricity and RTX 5080 (360 W) about CAD 142. The modeled difference is roughly CAD 16. 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.
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 9070 XT — same S-tier capability for 1080p Gaming, about CAD 620 cheaper · Value 97.
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 · RTX 4080 Super if…
- Your priorities resemble Balanced, 1080p Budget — it has higher Relative Value under those presets at the snapshot offers.
- Lower rated power matters: 320 W versus 360 W for RTX 5080.
- You can find it at or below its Strong Value threshold of CAD 1390 under balanced weights.
Choose B · RTX 5080 if…
- You prioritize 4K / VR, 3D Rendering — it earns the higher capability tier in those tracked scenarios.
- 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 CAD 1688 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: RTX 4080 Super or RTX 5080?
- Under the balanced preset and the 2026-09-27 offer frame, RTX 4080 Super has higher Relative Value under this configuration (72 vs 66). 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 5080 grades higher in 2 of 6 graded scenarios (4 tied) and is never graded lower. 1 scenario can't be graded for one of them (shown as N/A).
- At what price does the RTX 5080 become the better value?
- Holding the RTX 4080 Super offer dated in the 2026-09-27 frame fixed, the calculation flips in favour of the RTX 5080 at roughly CAD 1968 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.
