Who runs it
The site is built and maintained by Brian Sanchez, a software engineer, and has been online since April 2026. It is a one-person project: there is no newsroom and no team behind it. The tools, the hardware catalogue they read from and the articles all go through the same hands, which also means there is one person to write to when something is wrong.
The project started from a practical annoyance. Most PC-building questions have an answer that depends on two or three numbers — a card's rated power, a model's parameter count, a processor's relative speed — and yet the usual answer online is a verdict with the numbers left out. The tools here show the numbers, so the reasoning can be checked instead of taken on trust.
What you will find here
- Nine browser tools: a power supply calculator, a PC building simulator, a build configurator, a CPU/GPU bottleneck detector, an LLM VRAM calculator, an LLM inference speed estimator, an electricity cost calculator, a compilation time estimator and a GPU buy vs rent calculator.
- Reference pages: a hardware glossary and explainers such as DDR4 vs DDR5 and air vs liquid cooling.
- Guides and articles on choosing parts, assembling a machine and reading hardware specifications.
Everything is free to use and nothing requires an account.
Where the numbers come from
Every tool reads from one hardware catalogue: manufacturer power ratings, core counts, memory configurations and a relative performance index for processors and graphics cards. Detailed specifications on the comparison pages come from the TechPowerUp database, and game requirements come from each game's Steam store page. Both are linked where they are used.
The formulas, the constants and the known limits of each tool are written out on the methodology page. The results are estimates for planning a build, not measurements of a particular machine, and the pages say so where it matters.
How articles are written
Articles start from primary sources wherever they exist — manufacturer specifications, official announcements, a publisher's own requirement list — and from independent test data, which is cited in the piece. Drafts are prepared with the help of AI writing tools; before publication each article is checked against its sources and edited.
Articles do not accept payment for coverage, and no manufacturer reviews them before they go out. When a figure turns out to be wrong it is corrected in place, and the article's date of last update changes with it.
How the site is funded
Some links to shops are Amazon affiliate links: if you buy through one, the site earns a small commission at no extra cost to you. Those links are marked, and the site may also show advertising served by Google.
Neither affects the results. The calculators work from the catalogue figures and do not know which products have an affiliate link, and an article's recommendation is written before any link is added to it.
