This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p ultra, the EPYC 73F3 sets the ceiling at about 44 FPS, while the GeForce RTX 4090 could reach 111 FPS. In this scenario, the CPU limits the GPU potential by 60% (FPS gap: 67 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your EPYC 73F3 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 48% | CPU Limits GPU 50% | CPU Limits GPU 44% | CPU Limits GPU 60% |
| 1440p (2K QHD) | CPU Limits GPU 48% | CPU Limits GPU 50% | CPU Limits GPU 44% | CPU Limits GPU 58% |
| 4K (Ultra HD) | CPU Limits GPU 59% | CPU Limits GPU 60% | CPU Limits GPU 53% | CPU Limits GPU 60% |
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.

The EPYC 73F3 + GeForce RTX 4090 pairing runs this title with CPU utilization between 7% and 27% and GPU utilization between 32% and 66%. EPYC 73F3 keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 45% at 1080p to 56% at 4K, while CPU averages move from 18% to 19%.
The utilization pattern is relatively even. The GeForce RTX 4090 reaches 57% average at its highest-load preset, while the EPYC 73F3 peaks at 20% 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 18% and GPU 45%. At 1440p, that shifts to CPU 18% and GPU 47%, and at 4K it reaches CPU 19% and GPU 56%. 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 16% (7-25%) and GPU 57% (48-66%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 73F3 remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 73F3 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 73F3 and GeForce RTX 4090 will struggle to run Honkai: Star Rail at smooth framerates. At 1080p Ultra, you can expect around 44 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $3749 ($2100 CPU (Rank #447 Value) + $1649 GPU (Rank #77 Value)). Your EPYC 73F3 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 processor with a significantly better value rating. For example, the EPYC 4585PX is a great upgrade option for around $699 (Rank #66 for value) while costing less than your current CPU.
Your EPYC 73F3 is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your Honkai: Star Rail performance right now. CPU fully utilized 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 73F3 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.
