Estimates use approximate relative performance indexes and published power ratings, so treat them as a planning guide. Real results depend on the game, settings, drivers, memory and cooling.

Calculators work on one setup at a time. Change any setting to compare another build instantly.

Choosing a power supply before building a PC; Checking if a CPU or GPU upgrade is worth it; Matching mouse sensitivity across games; Estimating running costs, download times and odds.

They combine simple formulas with approximate relative performance and power data for popular parts. The goal is a realistic planning guide rather than a lab benchmark.

No. For a purchase decision, compare your estimate with independent benchmark reviews of the exact games and settings you care about.

It is designed for desktop parts. Laptop CPUs and GPUs run at lower power limits, so their real performance and power use are lower than the desktop figures.

Some imbalance is normal, because one part is always the limit. A GPU-limited system is ideal for gaming, while a heavy CPU limit means the graphics card is underused.

eDPI (effective DPI) is your mouse DPI multiplied by your in-game sensitivity. It lets you compare sensitivity between players who use different mice.
