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.

The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Performance Summary

The Xeon E5-2699A v4 + GeForce RTX 4090 pairing runs this title with CPU utilization between 7% and 28% and GPU utilization between 32% and 64%. Xeon E5-2699A v4 keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 42% at 1080p to 58% at 4K, while CPU averages move from 18% to 19%.

Bottleneck Analysis

The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 58% average at its highest-load preset, while the Xeon E5-2699A v4 peaks at 20% average, with no single component consistently acting as a hard bottleneck.

Resolution Scaling

At 1080p, averages sit around CPU 18% and GPU 42%. At 1440p, that shifts to CPU 19% and GPU 50%, and at 4K it reaches CPU 19% and GPU 58%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.

Optimal Settings Recommendation

4K (Ultra HD) Low is the most balanced preset based on this dataset. It runs around CPU 16% (7-26%) and GPU 58% (53-64%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Xeon E5-2699A v4 remains stable for consistent frame delivery.

Upgrade Insight

Current utilization does not show an urgent upgrade requirement for either component; the Xeon E5-2699A v4 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 Ideal Scenario (GPU Bottleneck): You typically want to see High GPU Utilization (90%+) and moderate CPU usage. This indicates your system is successfully pushing out graphics as fast as it can, without being held back by the CPU.
  • CPU Bottleneck: If you see High CPU Utilization (85%+) paired with lower GPU utilization, the CPU is struggling to compute game logic and prepare frames fast enough. The GPU sits waiting, often resulting in stuttering, inconsistent frame times, and lower overall FPS.
  • Engine Limits or Capped FPS: 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.

Frequently Asked Questions

1Can the Xeon E5-2699A v4 and GeForce RTX 4090 run Honkai: Star Rail well?

The Xeon E5-2699A v4 and GeForce RTX 4090 will struggle to run Honkai: Star Rail at smooth framerates. At 1080p Ultra, you can expect around 36 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.

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

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.

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

For Honkai: Star Rail, upgrading the CPU would have the biggest impact on performance. The Xeon E5-2699A v4 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.

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 Xeon E5-2699A v4 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 Xeon E5-2699A v4 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.
