GPU Pricing FAQ

Where do the prices come from?

All prices are sourced directly from Amazon.com product listings via an automated daily scraper. We show the listed price at the time of the last update — this is the price Amazon displays on the product page, not necessarily the lowest available from third-party sellers. The scraper visits each GPU's Amazon listing, reads the current buy-box price, and stores it with a timestamp. Only listings with a clear price displayed are included; "See price in cart" listings are captured when Amazon makes the price visible. Prices are stored per ASIN (Amazon's unique product identifier), so each physical product variant is tracked individually. This means the same GPU model can appear multiple times if different sellers list it separately. Always verify the current price on Amazon before purchasing, as prices can change at any time.

How often are prices updated?

Prices are updated automatically on a daily basis. The "Updated" date in the sidebar reflects the most recent price check. Our scraper runs through a curated list of GPU search queries on Amazon and follows each product to record its current price. If a listing hasn't been seen in over 7 days it is marked as unavailable and hidden from the default view. GPU prices can change frequently — flash sales, stock changes, and seller competition all affect pricing daily. Always check the current price on Amazon before purchasing, as the price shown on this site reflects the last recorded value and may differ from the live Amazon price.

Why do some prices show —?

A dash means the price was not available at the time of the last update. This typically happens when Amazon shows "See price in cart", when a listing is temporarily out of stock, or when the item is only available from third-party sellers at variable prices. The listing is still shown so you can click through and check the current price directly on Amazon.

What does $/TFLOP mean?

$/TFLOP is the price divided by the GPU's FP32 (single-precision floating point) performance in teraflops — lower is better. It measures raw compute value: how many dollars you spend for each trillion floating-point operations per second of processing power. This matters because it cuts through marketing tiers and lets you compare GPUs from different manufacturers and generations on equal footing. A common misconception is that a faster GPU always means better value — a GPU twice as fast at three times the price is actually worse value. TFLOPS figures are the manufacturer's rated FP32 peak throughput; real-world performance varies by workload and drivers, so $/TFLOP is most useful as a comparative guide rather than an absolute measure.

What is the Value Score and how is it calculated?

Value Score is our primary price-to-performance metric — higher is better. It is calculated as: Value Score = Performance Index ÷ Price × 100. Performance Index itself combines two signals: Performance Index = 0.70 × (TimeSpy ÷ 360) + 0.30 × (FP32 TFLOPS ÷ 1.65). The TimeSpy component (70% weight) reflects real-world gaming performance using 3DMark TimeSpy benchmark scores. The FP32 compute component (30% weight) ensures AI, rendering, and compute workloads are factored in. Both components normalise to 100 at the RTX 4090 reference point. For example, a GPU with a Perf Index of 50 priced at $300 has a Value Score of 16.67, while a GPU with Perf Index 45 at $200 scores 22.5 — lower absolute performance but significantly better value. GPUs without TimeSpy data use compute throughput only.

What does $/GB VRAM mean?

$/GB VRAM is the price divided by the amount of video memory. It's useful if VRAM capacity is your primary concern — for example, when running large AI models or working with high-resolution textures. Lower is better.

Why are $/TFLOP and $/GB VRAM blank for some listings?

Both metrics require a known price to calculate. If the price is unavailable (shown as —), these metrics cannot be computed and will also show —.

What does the Condition filter do?

Filters listings by condition as reported on Amazon. New means sold as new by Amazon or a seller. Used includes Amazon Renewed, refurbished, and used listings. Both are checked by default, showing all listings. Uncheck one to hide it.

How does the Price filter work?

The price checkboxes let you narrow results to a budget range. You can select multiple ranges — for example checking "$300–$500" and "$500–$800" together shows everything under $800. With nothing checked, all prices are shown.

How does the VRAM filter work?

Filters by the GPU's video memory capacity. The "20 GB+" bucket includes all cards with 20 GB or more. As with price, multiple options can be selected at once, and nothing checked means no filter is applied.

Are the product links affiliate links?

Yes. All links to Amazon products on best-gpu.com include our Amazon Associates affiliate tag (bestgpu-20). If you click a link and make a purchase within the attribution window, we may earn a small commission at no extra cost to you. This commission is how the site is funded. What the affiliate relationship does not affect: which GPUs appear in the table, how they are ranked, what prices are shown, or which cards are highlighted as best value. There are no ads, no sponsored placements, and no payments from GPU manufacturers or retailers to influence rankings. Every listing is included and ranked purely based on availability on Amazon and its calculated Value Score. The affiliate disclosure is also present in the page header and footer on every page.

Does using your affiliate link affect the price I pay?

No. The price you pay on Amazon is exactly the same whether you arrive via our affiliate link or navigate to Amazon directly. Amazon Associates commissions are paid by Amazon from their margin, not added to your purchase price. The affiliate tag in our URLs is only used by Amazon to attribute the referral — it has no effect on pricing, checkout, or any other part of your Amazon experience.

How do I find the best GPU for my budget?

Use the price filter in the sidebar to narrow the table to your budget range, then sort by Value Score (default) to see which GPU gives the most performance per dollar. The top result after filtering is the best value for that price range. Alternatively, browse the budget-specific pages: Best GPU Under $300, Best GPU Under $500, or Best GPU for Gaming 2026, which show pre-filtered picks with editorial context.

What GPU should I upgrade to from my current card?

Use the GPU Upgrade Calculator. Select your current GPU and the tool shows every available upgrade ranked by performance gain per dollar. As a general rule, a GPU upgrade is worthwhile when it delivers at least 20% more performance than your current card at a price that makes sense for your budget. The upgrade-from pages show a quick ranked list for the most common starting GPUs.

Does the site track used or refurbished GPUs?

Yes. The table includes both new and used/renewed listings sourced from Amazon. The Condition column shows whether each listing is new or used, and the Condition filter in the sidebar lets you show only new listings or only used listings. Used GPUs can offer significantly better value scores than new ones, but carry higher risk — always check the seller's return policy before purchasing a used GPU from Amazon.
