Bethesda's Creation Engine 2 is CPU-dependent, especially in cities, and requires an SSD for asset streaming. Optimization tends to favor AMD slightly, but generally requires powerful hardware to run smoothly.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 71 FPS. At 1440p, all settings exceed 60 FPS. At 4K, frame rates range from 34 to 54 FPS.
The GeForce RTX 4090 is 52% above the recommended GPU (GeForce RTX 2080) for Starfield. The EPYC 7251 is 18% below recommended, but 8% above minimum.
The EPYC 7251 sets the FPS ceiling at 1080p (low/medium/ultra), all 1440p settings, all 4k settings, while the GeForce RTX 4090 still has headroom. The FPS ceiling is closely matched at 1080p high.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k medium, the EPYC 7251 sets the ceiling at about 49 FPS, while the GeForce RTX 4090 could reach 83 FPS. In this scenario, the CPU limits the GPU potential by 41% (FPS gap: 34 FPS). Overall distribution: CPU limits 11/12 cells, GPU limits 0/12, balanced 1/12.
Your EPYC 7251 is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 12% | CPU Limits GPU 11% | Balanced | CPU Limits GPU 11% |
| 1440p (2K QHD) | CPU Limits GPU 15% | CPU Limits GPU 12% | CPU Limits GPU 9% | CPU Limits GPU 14% |
| 4K (Ultra HD) | CPU Limits GPU 39% | CPU Limits GPU 41% | CPU Limits GPU 35% | CPU Limits GPU 31% |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

The EPYC 7251 + GeForce RTX 4090 pairing runs this title with CPU utilization between 50% and 96% and GPU utilization between 38% and 99%. EPYC 7251 reaches high load in heavier scenarios, while GeForce RTX 4090 carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 80% at 1080p to 90% at 4K, while CPU averages move from 84% to 63%.
From a utilization perspective, this is a CPU-heavy load profile. At 1080p (Full HD) Low, the EPYC 7251 reaches 92% average load (87-96%), while the GeForce RTX 4090 remains comparatively lower at 49% (38-60%). This points to heavier CPU-side frame preparation work, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 84% and GPU 80%. At 1440p, that shifts to CPU 66% and GPU 86%, and at 4K it reaches CPU 63% and GPU 90%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
1440p (2K QHD) Medium is the most balanced preset based on this dataset. It runs around CPU 68% (62-75%) and GPU 91% (88-94%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 7251 remains stable for consistent frame delivery.
Both components are stressed near their limits in the heaviest presets (EPYC 7251: 92% avg, GeForce RTX 4090: 98% avg). A targeted upgrade should follow your target resolution: GPU first for higher image quality, CPU first for higher minimum FPS.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

Yes, the EPYC 7251 paired with the GeForce RTX 4090 can run Starfield smoothly up to 1440p achieving around 60 FPS at Ultra quality. Your GPU is 52% above the recommended specs, and your CPU is 18% below the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For Starfield, upgrading the CPU would have the biggest impact on performance. The EPYC 7251 is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 1080p medium, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
Starfield does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Starfield requires at minimum a Core i7-6800K (CPU) and GeForce GTX 1070 Ti (GPU) with 16 GB RAM and 125 GB (SSD Obrigatório) storage. For the recommended experience, you need a Core i5-10600K and GeForce RTX 2080 with 16 GB RAM. Your setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
These Starfield FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
