Performance Summary
The EPYC 7443P + GeForce RTX 4090 pairing runs this title with CPU utilization between 7% and 25% and GPU utilization between 29% and 55%. EPYC 7443P keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 41% at 1080p to 50% at 4K, while CPU averages move from 17% to 17%.
Load Interpretation
Neither component is close to saturation: CPU tops out at 25% 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 17% and GPU 41%. At 1440p, that shifts to CPU 17% and GPU 42%, and at 4K it reaches CPU 17% and GPU 50%. 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 15% (7-23%) and GPU 50% (46-55%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 7443P remains stable for consistent frame delivery.
Upgrade Insight
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 7443P 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
2Is there a more cost-effective setup to run Honkai: Star Rail?
This CPU + GPU combo costs approximately $2694 ($1045 CPU (Rank #247 Value) + $1649 GPU (Rank #77 Value)). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
3Which component should I upgrade first to improve Honkai: Star Rail performance?
This setup is already well-balanced for Honkai: Star Rail. No significant bottleneck - CPU and GPU are well matched across all settings. Both the EPYC 7443P and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
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 EPYC 7443P 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 EPYC 7443P 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.
