⚙️ METHODOLOGY
This calculator uses a scoring system calibrated against real-world benchmark data. Every CPU and GPU is given a performance score anchored to reference hardware, then blended per-game based on each title's CPU/GPU dependency ratio.
Factors accounted for: GPU rendering throughput · CPU game-thread speed · resolution pixel-count scaling · quality-preset shader complexity · per-game CPU weight · upscaling boost (DLSS / FSR / XeSS).
⚡ Upscaling: +20% at 1080p · +40% at 1440p · +65% at 4K. DLSS = NVIDIA RTX, FSR = all GPUs, XeSS = best on Intel Arc.
📏 Accuracy: Estimates are typically within 10–20% of real-world FPS. Driver versions, background apps, game patches, and RAM speed can all shift results.

❓ FREQUENTLY ASKED QUESTIONS
How accurate are these FPS estimates? ▸
Estimates are based on aggregated benchmark data and are typically within 10–20% of real-world results. Actual FPS varies with driver versions, background processes, game patches, RAM speed, and specific scene complexity. Use this as a planning tool, not an absolute benchmark.
What is a CPU / GPU bottleneck? ▸
A bottleneck occurs when one component limits the other. A GPU bottleneck means your GPU is the weak link — upgrading it raises FPS. A CPU bottleneck means your CPU can't feed the GPU fast enough, common in CS2, Minecraft, or strategy titles. At 4K, almost everything is GPU-limited, so CPU choice matters less.
What is DLSS / FSR / XeSS upscaling? ▸
AI-powered upscaling renders at a lower internal resolution then uses machine learning to reconstruct the target resolution. NVIDIA DLSS requires an RTX GPU and is generally the highest quality. AMD FSR is open-source and works on any GPU (even NVIDIA). Intel XeSS works on all GPUs but performs best on Arc hardware. Gains range from +20% at 1080p up to +65% at 4K.
Why does resolution impact FPS so dramatically? ▸
More pixels = more GPU work per frame. 1080p = 2.07M pixels. 1440p = 3.69M pixels (+78%). 4K = 8.29M pixels (+300% vs 1080p). Since this workload is almost entirely on the GPU, the CPU has diminishing impact at higher resolutions — which is why the best strategy for 4K gaming is maximising GPU tier, not CPU tier.
My GPU isn't in the list — what do I pick? ▸
Find your card's relative score on UserBenchmark, PassMark, or TechPowerUp GPU DB, then select the listed GPU closest to that score. For example, if your card benchmarks between an RTX 4060 and RTX 4070, pick whichever is closer to your benchmark result.
Does RAM speed or capacity affect FPS? ▸
Yes, but mostly at the margins. Dual-channel vs single-channel can swing 10–20% in CPU-bound games. RAM speed (3200 vs 6000 MHz) matters most on AMD Ryzen — especially X3D chips — and on integrated graphics. For most gaming with 16 GB+ dual-channel DDR4/DDR5, the impact is minimal and often within measurement noise.
What do "1% Low" FPS numbers mean? ▸
The "1% Low" is the 1st percentile of FPS over a gameplay session — essentially the worst 1% of frames. It's a better measure of perceived smoothness than average FPS because our brains are far more sensitive to sudden drops than sustained high framerates. A build with 120 avg / 40 1% low will feel much worse than 90 avg / 75 1% low.
How does the Bottleneck percentage work? ▸
We calculate theoretical maximum FPS if only the GPU was the limit (GPU FPS) and if only the CPU was the limit (CPU FPS). The bottleneck percentage shows how much the weaker component is holding back the stronger one. Under 28% difference = balanced build. Over 28% gap = meaningful bottleneck. The component with the lower theoretical FPS is the bottleneck.
Why are my real-world FPS lower than the estimate? ▸
Common causes: thermal throttling (CPU/GPU overheating and reducing clock speeds) · background apps (antivirus, Discord, browser tabs consuming CPU/RAM) · outdated drivers · single-channel RAM · storage bottleneck (HDD vs SSD can affect open-world streaming) · Windows power plan set to Balanced instead of High Performance · game running with vsync or frame-rate cap enabled.
What FPS should I aim for? ▸
30 FPS — Minimum playable for slow-paced single-player games. 60 FPS — The standard smooth target for most gaming. 144 FPS — The sweet spot for competitive multiplayer on a 144Hz monitor. 240+ FPS — Professional / esports level; diminishing returns for casual play but meaningful in top-tier competitive. Always match your target FPS to your monitor's refresh rate.

⚙️ 1. METHODOLOGY
Every CPU and GPU is assigned a performance score (1–100) calibrated against real-world benchmark data. The calculator blends GPU rendering throughput with CPU game-thread speed using each game's unique CPU/GPU dependency ratio, then applies resolution and quality multipliers.

We compute the theoretical FPS ceiling of the GPU alone and CPU alone. The gap between them is the bottleneck %. Under 28% = balanced build. Over 28% = the weaker component is meaningfully holding back the stronger one.
