Free CPU and GPU Bottleneck Calculator Widget
Give readers an interactive next step inside build guides, component reviews, community posts and support documentation.
Install the calculator widget in your CMS
WordPress block editor
Add a Custom HTML block where the calculator should appear, paste the iframe code and preview the post at desktop and mobile widths. WordPress.com plans and security plugins may restrict iframes; if the preview removes the tag, publish a preconfigured result link instead or ask the site administrator to allow this domain.
Webflow and other visual builders
Use an Embed or Custom Code element inside the main article container. Set the element to 100% width, keep the iframe title intact and avoid a parent container with a fixed height below 680 pixels. Test the published page rather than relying only on the design canvas.
Ghost, static sites and hand-written HTML
Insert the iframe in an HTML card or template partial. Static-site frameworks can render the same markup directly. If the site uses a content security policy, add https://bottleneckcalculator.biz to the page's frame-src directive. Do not add broad wildcard permissions.
Accessibility, privacy and performance
The supplied iframe includes a descriptive title, keyboard-operable component search and visible attribution. Keep the title attribute so screen-reader users know what the embedded region contains. Do not place the widget inside another interactive control or disable focus with a negative tabindex.
The embed does not require an account or upload hardware telemetry. The selected component IDs and scenario settings are used to calculate the result. A shared result stores those choices in a URL. Publishers should still disclose the third-party iframe in their own privacy and content policies where their jurisdiction or consent platform requires it.
Use one widget per page and retain loading="lazy" when the embed appears below the first screen. Component search now requests only the best matching models instead of downloading the entire catalogue, but several iframe instances still duplicate scripts, styles and layout work. If the calculator is the primary page action above the fold, remove lazy loading to prevent a delayed interaction.
Widget troubleshooting
| Problem | Likely cause | Fix |
|---|---|---|
| Blank frame | CMS sanitization or content security policy | Allow the exact domain or use a result link |
| Bottom controls are cut off | Iframe or parent height is too small | Use at least 680 pixels and remove overflow clipping |
| Horizontal scrolling | Fixed iframe width or narrow padded parent | Use width 100% and test the smallest article breakpoint |
| Slow page with several tools | Multiple embeds loaded | Keep one embed and link other scenarios |
Link to a preconfigured result
Calculator results use readable URL parameters. Create a pairing on the homepage, copy the result link and cite it beside a recommended build. The link remains useful because readers can change the resolution, frame target or workload themselves.

A strong implementation adds context around the widget: describe the intended game, display and budget, then remind readers that the estimate should be validated. This creates a more useful page than publishing a percentage alone.
Four checks before publishing
- Explain the target with help from the complete PC bottleneck guide.
- Link the score to the assumptions in the calculator methodology.
- Give readers a real next step with the diagnostic checklist.
- Keep the iframe title, attribution and mobile width intact.
How to earn trust with an embedded calculator
Place the widget after you have defined the hardware question. A component review might introduce it after measured benchmarks; a build guide can place it beside the intended resolution and refresh rate; a support article can use it as the first step in a diagnostic sequence. In every case, explain that the result is directional and link readers to the measurement they should perform next.
Recommended placement and sizing
Use the full width of the article column and allow at least 680 pixels of height on desktop. Avoid loading several copies on one page because each instance contains the complete searchable component catalogue. Lazy loading is appropriate below the fold, but a tool that is central to the page should be available without a confusing extra click.
Attribution and editorial independence
The built-in attribution identifies the model and gives readers access to its assumptions. Do not cover it, recolor it to invisibility or imply that an estimate is your own measured benchmark. You may surround the iframe with your own analysis, disclosures and test results. Editorial and non-deceptive commercial use is free.
Shareable result links as a citation tool
A configured URL records component IDs, resolution, target FPS and workload, but no personal telemetry. That makes it useful in forum answers, parts lists and review methodology notes. A reader can open the scenario, inspect the direction, change an input and share a revised comparison. This transparent interaction is more useful than a screenshot of an unexplained percentage.
Define the target, preserve attribution, state that the result is directional, and add a real-world verification step. If a CMS blocks iframes, use a normal result link instead.
Supporting publisher resources
Connect the embed to a clear explanation rather than leaving it isolated. Use the complete guide for diagnostic context, the tools hub for supporting measurements and the resources page for source-selection and licensing guidance.
Questions, custom placements and data corrections
If your publishing platform requires a different height, content-security-policy allowance or accessibility review, contact the Performance Desk. Please include the page type, column width and CMS. Component corrections should include the exact model name and a reproducible source so the shared catalogue can be reviewed.
