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
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, frame rates range from 59 to 65 FPS depending on quality settings. At 1440p, frame rates range from 55 to 62 FPS. At 4K, frame rates range from 52 to 68 FPS.
The GeForce RTX 4090 is 279% above the recommended GPU (GeForce GTX 1060) for Honkai: Star Rail. The EPYC 9015 is 42% above the recommended CPU (Core i7).
The EPYC 9015 determines the performance ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GPU has headroom.
At 1440p medium, the EPYC 9015 sets the ceiling at about 55 FPS, while the GeForce RTX 4090 could reach 119 FPS. In this scenario, the CPU limits the GPU potential by 54% (FPS gap: 64 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your EPYC 9015 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 47% | CPU Limits GPU 52% | CPU Limits GPU 41% | CPU Limits GPU 47% |
| 1440p (2K QHD) | CPU Limits GPU 49% | CPU Limits GPU 54% | CPU Limits GPU 44% | CPU Limits GPU 47% |
| 4K (Ultra HD) | CPU Limits GPU 50% | CPU Limits GPU 53% | CPU Limits GPU 44% | CPU Limits GPU 42% |
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 EPYC 9015 + GeForce RTX 4090 pairing runs this title with CPU utilization between 6% and 25% and GPU utilization between 37% and 73%. EPYC 9015 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 64% at 4K, while CPU averages move from 17% to 17%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 64% average at its highest-load preset, while the EPYC 9015 peaks at 18% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 17% and GPU 46%. At 1440p, that shifts to CPU 17% and GPU 56%, and at 4K it reaches CPU 17% and GPU 64%. 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 15% (6-24%) and GPU 64% (55-73%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 9015 remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 9015 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.

The EPYC 9015 and GeForce RTX 4090 will struggle to run Honkai: Star Rail at smooth framerates. At 1080p Ultra, you can expect around 59 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
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 Honkai: Star Rail, upgrading the CPU would have the biggest impact on performance. The EPYC 9015 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 EPYC 9015 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.
