Percentages show how much potential FPS of the stronger component is lost because the other component has a lower FPS ceiling.
🧠Methodology

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.

Performance Summary

The Core i9-13900F + GeForce RTX 4090 pairing runs this title with CPU utilization between 4% and 20% and GPU utilization between 26% and 55%. Core i9-13900F keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 38% at 1080p to 45% at 4K, while CPU averages move from 14% to 14%.

Load Interpretation

Neither component is close to saturation: CPU tops out at 20% and GPU at 55%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput. It also shows why low utilization does not automatically mean there is no FPS limiter.

Resolution Scaling

At 1080p, averages sit around CPU 14% and GPU 38%. At 1440p, that shifts to CPU 14% and GPU 38%, and at 4K it reaches CPU 14% and GPU 45%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.

Optimal Settings Recommendation

4K (Ultra HD) Low is the most balanced preset based on this dataset. It runs around CPU 11% (4-18%) and GPU 45% (35-55%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i9-13900F remains stable for consistent frame delivery.

Upgrade Insight

Current utilization does not show an urgent upgrade requirement for either component; the Core i9-13900F and GeForce RTX 4090 remain reasonably matched for this title.

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.

  • High GPU Load: You typically want to see High GPU Utilization (90%+) and moderate CPU usage when visual settings are heavy. This indicates the graphics pipeline is under strong load, but the exact FPS limiter should still be confirmed by the FPS ceiling analysis.
  • High CPU Load: If you see High CPU Utilization (85%+) paired with lower GPU utilization, the processor is handling a disproportionate share of frame preparation and game logic. That can point to CPU-side pressure, but it should not be treated as a direct replacement for FPS ceiling analysis.
  • Low CPU and GPU Load: If both CPU and GPU utilization are relatively low, it means the hardware is waiting on something else. This could be a game engine limitation, poorly optimized code, or an artificial framerate cap like VSync holding performance back. It does not mean both parts are equally fast in FPS terms.

Frequently Asked Questions

1Can the Core i9-13900F and GeForce RTX 4090 run Honkai: Star Rail well?

Yes, the Core i9-13900F paired with the GeForce RTX 4090 can run Honkai: Star Rail smoothly up to 4k achieving around 74 FPS at Ultra quality. Your GPU is 279% above the recommended specs, and your CPU is 127% above the recommended requirements.

2Is there a more cost-effective setup to run Honkai: Star Rail?

This CPU + GPU combo costs approximately $2185 ($536 CPU (Rank #207 Value) + $1649 GPU (Rank #77 Value)). Your GeForce RTX 4090 provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end card with a significantly better value rating.

3Which component should I upgrade first to improve Honkai: Star Rail performance?

Your GeForce RTX 4090 is already a top-tier graphics card. While it's technically the limiting factor here (which means you are fully utilizing your GPU's visual horsepower exactly as intended), there is no meaningful upgrade path that would drastically improve your Honkai: Star Rail performance right now. GPU fully utilized at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 4k low, 4k medium.

4Does this setup support Frame Generation for Honkai: Star Rail?

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.

5What are the minimum and recommended specs for Honkai: Star Rail?

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 Core i9-13900F and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.

6How accurate are these Honkai: Star Rail FPS estimates for the Core i9-13900F and GeForce RTX 4090?

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.
