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.

They grade identically in all 6 graded scenarios — the tier table won't decide this one, so compare price and Value below. 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 2026-08-13 offer frame. How tiers are assigned →

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.
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, Arc A310 (50 W) adds about $16 in modeled electricity and RX 6400 (55 W) about $18. The modeled difference is roughly $2. This uses rated power as a common comparison input, not a promise of wall-power consumption.

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.
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.
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 A · Arc A310 if…
- Your priorities resemble 1080p Budget — it has higher Relative Value under those presets at the snapshot offers.
- Lower rated power matters: 50 W versus 55 W for RX 6400.
- You can find it at or below its Strong Value threshold of $19 under balanced weights.
Choose B · RX 6400 if…
- Its platform or feature fit matters more to you than the tracked scenario and price leads shown here.
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: Arc A310 or RX 6400?
- Under the balanced preset and the 2026-08-13 offer frame, they are practically even in Relative Value (23 vs 20). 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?
- They grade identically in all 6 graded scenarios — the tier table won't decide this one, so compare price and Value below. 1 scenario can't be graded for one of them (shown as N/A).
- 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.
