Performance Limiter Analysis

Ryzen 5 PRO 4655G|GeForce RTX 4090

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.

📈Analysis

At 4k ultra, the Ryzen 5 PRO 4655G sets the ceiling at about 31 FPS, while the GeForce RTX 4090 could reach 81 FPS. In this scenario, the CPU limits the GPU potential by 62% (FPS gap: 50 FPS). Overall distribution: CPU limits 7/12 cells, GPU limits 3/12, balanced 2/12.

Verdict

CPU Limits GPU

Your Ryzen 5 PRO 4655G is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.

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.

A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Performance Summary

The Ryzen 5 PRO 4655G + GeForce RTX 4090 pairing runs this title with CPU utilization between 54% and 93% and GPU utilization between 20% and 60%. Ryzen 5 PRO 4655G stays in a controlled operating range, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 30% at 1080p to 50% at 4K, while CPU averages move from 68% to 74%.

Load Interpretation

The utilization pattern is relatively even. The GeForce RTX 4090 reaches 50% average at its highest-load preset, while the Ryzen 5 PRO 4655G peaks at 74% average. This suggests a fairly controlled load distribution, but the actual FPS-limiting side should still be read from the limiter analysis above.

Resolution Scaling

At 1080p, averages sit around CPU 68% and GPU 30%. At 1440p, that shifts to CPU 74% and GPU 42%, and at 4K it reaches CPU 74% and GPU 50%. 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 74% (56-91%) and GPU 50% (40-60%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen 5 PRO 4655G remains stable for consistent frame delivery.

Upgrade Insight

Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 5 PRO 4655G 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.

2Is there a more cost-effective setup to run Hearts of Iron IV?

This CPU + GPU combo costs approximately $1814 ($165 CPU (Rank #188 Value) + $1649 GPU (Rank #77 Value)). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #5 for value).

3Which component should I upgrade first to improve Hearts of Iron IV performance?

For Hearts of Iron IV, upgrading the CPU would have the biggest impact on performance. The Ryzen 5 PRO 4655G 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: 1440p high, 1440p medium, 1440p ultra, 4k high, 4k low, 4k medium, 4k ultra. GPU fully utilized at: 1080p high, 1080p low, 1080p medium.

4Does this setup support Frame Generation for Hearts of Iron IV?

Hearts of Iron IV currently only supports AFMF (AMD Fluid Motion Frames) for frame generation, which is an AMD-exclusive technology. Because you are using an NVIDIA GPU, you cannot use Frame Generation for this specific game.

5What are the minimum and recommended specs for Hearts of Iron IV?

Hearts of Iron IV requires at minimum a Core 2 Quad Q9400 (CPU) and GeForce GTX 470 (GPU) with 4 GB RAM and 2 GB storage. For the recommended experience, you need a Core i5-750 and GeForce GTX 570 with 4 GB RAM. Your Ryzen 5 PRO 4655G and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.

6How accurate are these Hearts of Iron IV FPS estimates for the Ryzen 5 PRO 4655G and GeForce RTX 4090?

These Hearts of Iron IV 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.
