The balance changes by game, scene, resolution, graphics settings, and target FPS.
How the CPU and GPU determine FPS
Each frame depends on work from both the CPU and GPU. The CPU handles tasks such as game simulation, AI, and preparing draw calls; the GPU renders the frame. If either stage takes longer than the other, it can hold back the pace of frame production. Intel describes the CPU-bound case as the CPU failing to supply work quickly enough for the GPU, while in a GPU-bound case the graphics card takes longer to finish rendering (Intel’s low-FPS guidance).
This can vary within one game. A crowded scene with many characters or a large world may demand more CPU work; detailed effects and high-resolution graphics may load the GPU more heavily. That is why a processor upgrade can help in one title or scene and barely affect another.
How much difference can a CPU make?
Published benchmarks show why a universal estimate would be misleading: CPU differences depend on the test setup and game. The figures below are specific results from named publications, not predicted gains for every PC.

| Test | Reported result | What it shows |
|---|---|---|
| Tom’s Hardware rasterization suite, tested GPU tiers (2024) | The fastest-to-slowest CPU performance spread grew from 3% with an RTX 3050 to 36% with an RTX 4080. | CPU differences can become more visible when a faster GPU has more headroom. The spread applies to that suite and those configurations, not all games or systems. (Tom’s Hardware) |
| Tom’s Hardware 4K Ultra tests (2024) | Moving from a Core i7-8700K to a Core i9-13900K or Ryzen 7 7800X3D improved performance by 8–9%. | GPU performance was the main bottleneck in nearly every game in that 4K test suite, compressing CPU differences. (Tom’s Hardware) |
| Gears of War: E-Day, 1080p High (Tom’s Hardware, 2026) | The Ryzen 7 9800X3D performed 42% better than the Ryzen 5 7600X. | This is a result for one CPU-heavy title and setting, not a general upgrade expectation. In the same publication’s tested setup, the 1440p comparison reached a GPU-bound ceiling around 130 FPS. (Tom’s Hardware) |
| Space Marine 2 and Assetto Corsa Competizione tests (TechSpot, 2026) | CPU-limited behavior persisted at 1440p in selected tests. | Higher resolution often shifts more work to the GPU, but does not guarantee a GPU limit. In a separate 1440p Ultra test, TechSpot reported an RTX 5090 average cap of 133 FPS, increasing to 164 FPS with DLSS Quality. (TechSpot) |
These results do not establish a typical FPS gain from upgrading a CPU across all PCs and games. CPU benchmark charts often use low resolutions or powerful GPUs to make processor differences easier to see before the GPU becomes the limit. Treat those results as comparisons under their stated test conditions, not forecasts for every setup.
How to tell whether your CPU is limiting FPS
- Choose a repeatable scene. Use a section of a game you actually play, and keep the scene, resolution, graphics preset, upscaling setting, and background workloads as consistent as possible.
- Check GPU activity and CPU activity by logical processor. In Windows Task Manager, open the CPU graph’s menu and change the display to logical processors. A game can heavily use one or a few cores without showing 100% total CPU usage. Intel recommends checking GPU benchmarks as well as CPU benchmarks because games differ in how much they rely on the GPU (Intel gaming guidance).
- Change one graphics setting at a time. Lowering resolution or a GPU-heavy quality setting can test whether the GPU has headroom. If FPS barely changes while GPU activity falls, a CPU limit becomes more plausible. Lowering draw distance may reduce CPU work in some games.
- Look for a consistent pattern, not one utilization snapshot. Overlays can help, but a single percentage is not a definitive diagnosis. Intel’s developer guidance describes correlating CPU threads and GPU work in traces; in its example, gaps in GPU activity while the CPU is at maximum capacity indicate a CPU-bound case (Intel’s gaming performance analysis).
These checks are clues rather than proof on their own. Repeat them in the same scene and settings: the limiting component can change between scenes, and background work can affect what you observe.

Should you upgrade your CPU or GPU?
Base the choice on the component that is holding back the games and frame rates you care about—not resolution alone. Compare results in the actual titles you play, including average FPS and low-percentile frame rates when available. Low-percentile results help show whether performance dips are undermining smoothness even when the average looks adequate.
- A CPU upgrade is more likely to help if repeatable tests show CPU-limited behavior in important games and your GPU could render faster in those scenes.
- A GPU upgrade is more likely to help if the graphics card is consistently the limiting stage. A faster GPU can deliver little extra FPS if the CPU cannot keep it supplied with work.
- At 4K or demanding visual settings, GPU limits are common, but CPU-heavy games and high-FPS targets can still be exceptions.
- Before choosing a part, check motherboard and platform compatibility, cooling and power constraints, local pricing, and benchmarks for your games. There is no universally best-value CPU established by these comparisons.
The Ryzen 7 9800X3D’s 42% lead over the Ryzen 5 7600X in Tom’s Hardware’s 1080p High Gears of War: E-Day test is an example of strong, title-specific CPU scaling—not a blanket purchase recommendation. Confirm current independent benchmarks and compatibility for your system before buying.
