A free set of seven browser-based GPU tools that help you compare graphics cards, work out running and ownership costs, check used prices, identify your card, tune Windows settings, and decide whether to buy, rent, repair, or replace — no download and no sign-up.
Quick answer. Whether you’re buying your first graphics card, weighing a used deal, sizing up a cloud GPU for AI, or trying to squeeze more out of the card you own, these tools give you a fast, data-backed answer. Each one runs in your browser, works without an account, and shows its results as plain text you can share or reference. Pick a tool below to get started.
Buying and cost tools
GPU Comparison Tool Put any two or three graphics cards head to head — VRAM, bandwidth, power, separate gaming and AI scores, new and used prices, and cloud rental cost — with the winner highlighted on every row and a plain-English verdict on which to choose. Start here when you’re deciding between specific cards.
Buy, Build, or Rent a GPU? Answer a few questions about your workload, hours, and budget and get a clear buy, build, or rent recommendation, complete with break-even math and a suggested card. The fastest way to know whether owning a GPU or renting one in the cloud actually makes sense for you.
GPU Electricity Cost Calculator See exactly what any GPU costs to run per month and per year in your US state, and how that power bill compares with renting the same card in the cloud. Essential for understanding the true cost of ownership before you buy.
Used GPU Price Checker Enter a used card, its condition, and the asking price to see the fair market range and whether the listing is a deal, fair, or overpriced. Check it before you message a seller so you negotiate from a real number.
Identify and optimize tools
What GPU Do I Have? Detect your graphics card straight from your browser and view its full specs — no download, a lightweight alternative to GPU-Z for identification. Handy for checking a prebuilt, helping a friend, or confirming what’s really in your machine.
Hardware-Accelerated GPU Scheduling (HAGS) Checker Get a clear on-or-off recommendation for HAGS based on your GPU and use case, plus step-by-step instructions to change it in Windows. Especially useful for RTX 40/50 owners who want DLSS Frame Generation.
Fix or upgrade tools
GPU Repair or Replace? Got a dead or dying card? Compare the repair cost against the card’s used and new value and get a clear verdict — fix it, or put the money toward a replacement. Includes typical repair-cost ranges and what’s safe to DIY.
Why use these tools
Every tool here is built on the same principles: give you a direct answer, show the math behind it, and never hide the result behind a login or a paywall. Results render as real, shareable content, so you can bookmark a comparison, send a colleague a used-price verdict, or link a friend to exactly the answer they need. Prices, scores, and rates are reference figures we review and keep current — last updated {MONTH_YEAR}.
When a tool points to renting, that’s often the practical move: cloud GPUs let you access the latest and largest cards by the hour, with no upfront cost, no power bill, and nothing to build. If that fits your workload, you can rent a cloud GPU here.
Frequently asked questions
(This FAQ carries FAQPage schema — safe here because the hub embeds no tool shortcode. Do not repeat FAQPage on the individual tool pages.)
Are these GPU tools free? Yes. Every tool runs in your browser, requires no account or download, and is free to use as often as you like.
Do I need to install anything? No. The tools work entirely on the web. The GPU detector even identifies your card in the browser without any software.
How accurate are the results? The tools use current reference specs, prices, and rates and transparent formulas, and each explains its methodology. Treat the results as a strong, well-grounded guide, and confirm exact figures — like a specific repair quote or benchmark — for your own situation.
Which tool should I start with? If you’re choosing between cards, start with the comparison tool. If you’re deciding whether to own or rent, use the buy, build, or rent wizard. If you’re not sure what card you already have, run the GPU detector.
