At 4k medium, the Core i5-12400F sets the ceiling at about 76 FPS, while the GeForce RTX 4090 could reach 136 FPS. In this scenario, the CPU limits the GPU potential by 44% (FPS gap: 60 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core i5-12400F 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 29% | CPU Limits GPU 31% | CPU Limits GPU 25% | CPU Limits GPU 32% |
| 1440p (2K QHD) | CPU Limits GPU 24% | CPU Limits GPU 26% | CPU Limits GPU 23% | CPU Limits GPU 28% |
| 4K (Ultra HD) | CPU Limits GPU 42% | CPU Limits GPU 44% | CPU Limits GPU 42% | CPU Limits GPU 37% |
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.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

The Core i5-12400F + GeForce RTX 4090 pairing runs this title with CPU utilization between 8% and 26% and GPU utilization between 36% and 67%. Core i5-12400F keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 46% at 1080p to 58% at 4K, while CPU averages move from 19% to 18%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 58% average at its highest-load preset, while the Core i5-12400F peaks at 20% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 19% and GPU 46%. At 1440p, that shifts to CPU 18% and GPU 58%, and at 4K it reaches CPU 18% and GPU 58%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
1440p (2K QHD) Low is the most balanced preset based on this dataset. It runs around CPU 16% (8-23%) and GPU 58% (49-66%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i5-12400F remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core i5-12400F and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization & Bottlenecks: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. This is the key to identifying performance bottlenecks in any system.

Yes, the Core i5-12400F paired with the GeForce RTX 4090 can run Honkai: Star Rail smoothly up to 1440p achieving around 79 FPS at Ultra quality. Your GPU is 279% above the recommended specs, and your CPU is 9% below the recommended requirements.
This CPU + GPU combo costs approximately $1759 ($110 CPU (Rank #30 Value) + $1649 GPU (Rank #77 Value)). Your build is already very cost-efficient, but if you want even more FPS, the next good option is upgrading the CPU. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #5 for value).
For Honkai: Star Rail, upgrading the CPU would have the biggest impact on performance. The Core i5-12400F 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 high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
Honkai: Star Rail 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.
Honkai: Star Rail requires at minimum a Core i3 (CPU) and GeForce GTX 650 (GPU) with 6 GB RAM and 20 GB storage. For the recommended experience, you need a Core i7 and GeForce GTX 1060 with 8 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 Honkai: Star Rail 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.
