This is a directional estimate, not a guaranteed FPS prediction. Confirm with frame-time and utilization measurements in your actual software.

Use the exact parts in your PC, model the resolution and frame target you really use, read the limiting direction, then verify that prediction in the same game or application.
In Windows, open Task Manager and choose the Performance tab. Use the full processor and graphics-card names. On a laptop, select the discrete GPU used by the game, not only the integrated graphics entry.
Check a gaming laptop correctly →Choose the display resolution, intended frame rate and workload you actually run. A 1080p competitive target and a 4K quality target can produce opposite limits from the same hardware.
See how resolution changes the limit →Start with CPU-limited, GPU-limited or balanced. The percentage describes a relative tier gap inside this model. It is not the percentage of FPS lost and it is not a hardware-health score.
Interpret the bottleneck percentage →Repeat one scene, record frame time and utilization, then change one variable. A prediction becomes useful only when the measured response points to the same limiting stage.
Use the PC bottleneck checklist →A balance estimate is not a physical compatibility checker. Use the published calculation and limitations to inspect the model, then build a measured CPU-or-GPU upgrade decision.
The result compares normalized CPU and GPU tier indices after applying the selected resolution, frame target and workload factors. The percentage is the rounded distance between the two adjusted headroom values. It identifies the lower side as the first path to investigate; it does not claim that the same percentage of FPS is lost.
| Input | Why it changes the balance |
|---|---|
| Resolution | Changes the graphics work performed for each rendered frame. |
| Frame target | Changes the time available for CPU frame preparation. |
| Workload | Adds different compute, encoding and memory pressure. |
Every result links to a validation checklist. The complete formula, current coefficients, worked example, limitations and revision history are published in the bottleneck calculator methodology. For focused frame-time and resolution calculations, browse the PC performance calculator collection.
Direct answer: AMD Ryzen 7 9800X3D and NVIDIA GeForce RTX 5090 move from a CPU limit at 1080p to a balanced result at 1440p and a GPU limit at 4K in this 120 FPS gaming scenario. Resolution changes the work per frame, so one universal percentage would hide the useful part of the answer.
| Resolution | Model result | Relative tier gap | Best next check |
|---|---|---|---|
| 1920 × 1080 (Full HD) | CPU-limited | 16% | Busiest CPU-thread time and unused GPU capacity |
| 2560 × 1440 (QHD) | Well balanced | 5% | 1% lows, temperatures and repeatability |
| 3840 × 2160 (4K UHD) | GPU-limited | 30% | GPU frame time after one quality or resolution change |
The gap is a comparison of adjusted headroom, not a promise that the system loses the same percentage of frames. Open the full three-resolution pairing analysis, reproduce the scenario in the calculator, and use the linked checks to test the prediction.
A real diagnosis connects a predicted limit to the way your system behaves. These are the three signals worth checking before you spend.
A CPU can limit a game with modest total usage when one critical thread is saturated. A GPU can sit at 99% and be operating exactly as intended.
Read utilization correctly →1% lows and the frame-time graph expose stalls that an average FPS figure hides.
Understand frame time →Lower resolution, repeat the same scene and compare. The response tells you which stage deserves attention.
Run the 20-minute test →
At 1080p and 240 FPS, the CPU has only a few milliseconds to prepare each frame. At native 4K, the GPU processes four times as many pixels as 1080p. The same PC can be CPU-limited in one scenario and GPU-limited in the next.
Use a repeatable 20-minute test with utilization, frame time, temperatures and controlled setting changes to identify the part limiting your PC.

View all questions →No. Every workload has a slowest stage. It matters when that stage prevents the performance or smoothness you need.
It is a scenario-aware estimate based on normalized component tiers. Real games, settings, cooling and background work still need measurement.
Do not treat a single threshold as a verdict. A small mismatch is normal; investigate when the predicted limit aligns with an unmet target.
The result points to the limiting path and practical checks first. Product choice should follow budget, compatibility and measured need.
