At 1440p high, the GeForce RTX 4090 sets the ceiling at about 138 FPS, while the Ryzen 7 5800X has headroom up to 176 FPS. In this scenario, the GPU limits the CPU potential by 22% (FPS gap: 38 FPS). Overall distribution: GPU limits 9/12 cells, CPU limits 0/12, balanced 3/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 5800X frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 8% | GPU Limits CPU 15% | GPU Limits CPU 19% | GPU Limits CPU 15% |
| 1440p (2K QHD) | GPU Limits CPU 10% | GPU Limits CPU 15% | GPU Limits CPU 22% | GPU Limits CPU 18% |
| 4K (Ultra HD) | Balanced | Balanced | GPU Limits CPU 10% | Balanced |
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 Ryzen 7 5800X + GeForce RTX 4090 pairing runs this title with CPU utilization between 47% and 92% and GPU utilization between 16% and 60%. Ryzen 7 5800X stays in a controlled operating range, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 28% at 1080p to 47% at 4K, while CPU averages move from 66% to 69%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 47% average at its highest-load preset, while the Ryzen 7 5800X peaks at 70% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 66% and GPU 28%. At 1440p, that shifts to CPU 70% and GPU 40%, and at 4K it reaches CPU 69% and GPU 47%. 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 69% (47-91%) and GPU 47% (34-60%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen 7 5800X remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 7 5800X and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Ryzen 7 5800X paired with the GeForce RTX 4090 can run Hearts of Iron IV smoothly up to 4k achieving around 95 FPS at Ultra quality. Your GPU is 870% above the recommended specs, and your CPU is 988% above the recommended requirements.
This CPU + GPU combo costs approximately $1829 ($180 CPU (Rank #55 Value) + $1649 GPU (Rank #77 Value)). Your GeForce RTX 4090 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 card with a significantly better value rating.
Your GeForce RTX 4090 is already a top-tier graphics card. While it's technically the limiting factor here (which means you are fully utilizing your GPU's visual horsepower exactly as intended), there is no meaningful upgrade path that would drastically improve your Hearts of Iron IV performance right now. GPU fully utilized at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k high.
Hearts of Iron IV 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.
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 7 5800X and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
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.
