FAQ
Common questions about upgrade-gpu.com.
How does the calculator work?
You enter your current GPU. We look up every GPU currently listed on Amazon for your market, calculate the performance gain over your card using a unified Perf Index, and rank them by % gain per $100 (higher is better). The best-value option becomes your verdict.
What is the Perf Index?
A single number that blends two benchmarks: 3DMark Time Spy (70%) and FP32 throughput in teraflops (30%). Formula:
0.70 × (TimeSpy ÷ 360) + 0.30 × (TFLOPs ÷ 1.65)
Both inputs are from publicly available benchmark databases (3DMark and TechPowerUp). No marketing claims.
What does "% gain per $100" mean?
It measures how much faster you get per $100 spent. Formula:
(% faster than your current card ÷ listing price) × 100
A score of 25+ is excellent value. 8–25 is reasonable. Under 8 usually means waiting for a price drop or next-gen release is the better call.
How fresh is the price data?
Prices are scraped from Amazon daily. Listings that haven't been seen in 7 days are removed from results. New and used conditions are tracked separately.
Which markets are supported?
Currently US (amazon.com) and UK (amazon.co.uk). Canada, France, Germany, and Australia are in progress.
Are the Amazon links affiliate links?
Yes. When you click "Buy on Amazon" and make a purchase, we may earn a small commission at no extra cost to you. This is how the site stays free and independent.
Affiliate commissions do not influence rankings. Cards are ranked purely by performance gain per dollar, and we never promote a listing because it pays more.
Why isn't my GPU in the list?
We track 184+ GPU models. If yours is missing, it's likely because it predates our benchmark database or uses a very uncommon name variant. We add models regularly.
Are used GPU listings included?
Yes, and they're flagged clearly. Used cards are often excellent value; a used RTX 4070 can outperform a new RTX 3080 at a lower price. The condition badge (New / Used) is shown on every listing.
Is the benchmark data accurate?
We source specs from 3DMark's official database and TechPowerUp GPU database. Time Spy is a synthetic rasterization benchmark, which correlates well with gaming performance at 1440p but won't reflect ray tracing or compute-heavy workloads equally. Real-world results always depend on your specific game, resolution, and CPU.
Who made this?
upgrade-gpu.com is an independent tool built and maintained by a single developer. It's a sister site to best-gpu.com, which shows the full GPU price/performance table for all markets.
