1Can the EPYC 9355P and GeForce RTX 4090 run Honkai: Star Rail well?
The EPYC 9355P and GeForce RTX 4090 will struggle to run Honkai: Star Rail at smooth framerates.
Being turn-based, extreme FPS is less critical here. The game features high-fidelity models and uses considerable storage for audio and cutscenes. 8GB of RAM is recommended for smooth operation.
This game has a built-in FPS cap of 60 FPS
Performance Report
The GeForce RTX 4090 is 279% above the recommended GPU (GeForce GTX 1060) for Honkai: Star Rail. The EPYC 9355P is 351% above the recommended CPU (Core i7).
No major FPS-ceiling mismatch detected. The GeForce RTX 4090 and EPYC 9355P stay close in effective frame-generation ceiling across the tested resolutions and quality settings.

The EPYC 9355P + GeForce RTX 4090 pairing runs this title with CPU utilization between 4% and 21% and GPU utilization between 29% and 66%. EPYC 9355P keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 43% at 1080p to 55% at 4K, while CPU averages move from 14% to 14%.
The utilization pattern is relatively even. The GeForce RTX 4090 reaches 56% average at its highest-load preset, while the EPYC 9355P peaks at 16% average. This suggests a fairly controlled load distribution, but the actual FPS-limiting side should still be read from the limiter analysis above.
At 1080p, averages sit around CPU 14% and GPU 43%. At 1440p, that shifts to CPU 14% and GPU 46%, and at 4K it reaches CPU 14% and GPU 55%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Low is the most balanced preset based on this dataset. It runs around CPU 12% (5-20%) and GPU 56% (46-66%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 9355P remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 9355P 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.

The EPYC 9355P and GeForce RTX 4090 will struggle to run Honkai: Star Rail at smooth framerates.
This CPU + GPU combo costs approximately $4675 ($3026 CPU (Rank #287 Value) + $1649 GPU (Rank #77 Value)). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
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 9355P 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.
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 EPYC 9355P and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
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.
