Bottleneck calculator
Find out whether your processor or graphics card is holding the other back, and by how much.
What GPU do I have?
Reads your graphics card straight from your browser, then shows what it can reach. Nothing to install.
Upgrade advisor
CPU or GPU first? The smallest change that actually helps — including when the answer is neither.
Frame rate target
Pick 144 Hz and work backwards to the hardware that reaches it.
VRAM checker
Is 8 GB still enough at this resolution, and what to do if it is not.
PSU wattage calculator
How much power supply your build genuinely needs. Accounts for transient spikes, not just nameplate TDP.
GPU & CPU comparison
Head-to-head across resolutions and games, both measured against the same partner.
Build plannerSoon
Plan a full system and check every part works together before you buy.
Why one engine matters
Most hardware tool sites bolt each calculator on separately, with its own invented formula. That is why their answers contradict each other — a site can tell you a pairing is fine on one page and badly matched on another.
Ours all read from a single model and a single dataset, so they agree with each other by construction. When we improve the calibration, every tool on the site gets more accurate at once.
