FPS Estimator

FPS estimator & build comparison

Estimate · not benchmarked

This free FPS calculator estimates frame rates for any CPU and GPU pairing across today’s most-played games — or switch to compare mode to put two builds head to head. Figures model native rendering at the chosen preset — no DLSS/FSR upscaling or frame generation, so enabling those in-game will push real numbers higher. Recalibrated July 2026 against published benchmarks. Use it to plan an upgrade or sanity-check a build; actual results vary by game version, drivers, and tuning.

Planning a build in Harrow? Let’s get the parts right.

This estimator is a starting point — the harder questions are which CPU and GPU actually pair well for your budget, your monitor, and the games you play, without paying for performance you’ll never see. That’s what we do at TechSavant.

We build custom gaming and work PCs to order, handle repairs and upgrades on existing machines, and give straight buying advice with no pressure to over-spend. We’re based in Harrow and cover North West London, collecting and delivering across the area rather than running a shopfront.

FPS calculator — frequently asked questions

How accurate is this FPS calculator?

The model is calibrated against published native-rendering benchmarks (July 2026) and is typically within ~15% of measured averages for common CPU and GPU pairings. Treat results as a planning estimate for comparing builds — not a guaranteed frame rate. Real FPS varies by map, scene, drivers and settings.

Why is my real FPS different from the estimate?

In-game FPS swings heavily with what’s on screen. Esports titles like CS2 can vary ±30% between benchmark maps and live matches, and background apps, RAM speed, thermals and game patches all shift results. The estimator models a typical scene at the chosen resolution and preset.

Does the FPS calculator include DLSS or FSR?

No — figures model native rendering with no DLSS/FSR upscaling or frame generation. Turning those on in-game will push real frame rates higher: often 40%+ with upscaling and 2–3× with frame generation in supported titles.

What does CPU-bound or GPU-bound mean?

Every game is limited by whichever part runs out of headroom first. GPU-bound means the graphics card sets your frame rate (common at 1440p/4K); CPU-bound means the processor does (common in esports at 1080p). The per-game tags and the system balance bar show which part limits you — so you can see whether a CPU or GPU upgrade would actually gain FPS before spending money. Unsure? Ask us — upgrade advice is what we do.

How this works: Each part gets a synthetic performance score from its specs (architecture, clocks, cores/shaders, memory). Estimated FPS takes the lower of the CPU-bound and GPU-bound limit per game, then scales by resolution and preset. Game demand is calibrated against published native-raster benchmarks (July 2026) — the model was anchored to real measurements for reference builds from entry level (i5 + RTX 4060 class) up to 9800X3D + RTX 5090 — but this is an estimate, not a measured result. In-game FPS varies heavily by map, scene and settings; esports titles like CS2 can swing ±30% between benchmark maps and live matches. Use it to compare builds, not as a guaranteed frame rate.
