Performance Report
At 1080p, all quality settings exceed 128 FPS. At 1440p, all settings exceed 102 FPS. At 4K, all settings exceed 75 FPS.
The GeForce RTX 4090 is 870% above the recommended GPU (GeForce GTX 570) for Hearts of Iron IV. The Xeon Gold 5220 is 862% above the recommended CPU (Core i5-750).
At lower resolutions (4k low), the Xeon Gold 5220 determines the performance ceiling. As graphical load increases at (all 1080p settings, all 1440p settings), the GeForce RTX 4090 takes over as the primary performance factor. The system is well balanced at 4k (medium/high/ultra).
At 1080p low, the GeForce RTX 4090 sets the ceiling at about 120 FPS, while the Xeon Gold 5220 has headroom up to 257 FPS. In this scenario, the GPU limits the CPU potential by 53% (FPS gap: 137 FPS). Overall distribution: GPU limits 8/12 cells, CPU limits 1/12, balanced 3/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Xeon Gold 5220 frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 53% | GPU Limits CPU 52% | GPU Limits CPU 53% | GPU Limits CPU 43% |
| 1440p (2K QHD) | GPU Limits CPU 25% | GPU Limits CPU 25% | GPU Limits CPU 28% | GPU Limits CPU 16% |
| 4K (Ultra HD) | CPU Limits GPU 7% | Balanced | Balanced | 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 Xeon Gold 5220 + GeForce RTX 4090 pairing runs this title with CPU utilization between 48% and 100% and GPU utilization between 11% and 56%. Xeon Gold 5220 stays in a controlled operating range, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 19% at 1080p to 44% at 4K, while CPU averages move from 72% to 74%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 44% average at its highest-load preset, while the Xeon Gold 5220 peaks at 76% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 72% and GPU 19%. At 1440p, that shifts to CPU 76% and GPU 35%, and at 4K it reaches CPU 74% and GPU 44%. 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 74% (48-100%) and GPU 44% (33-56%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Xeon Gold 5220 remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Xeon Gold 5220 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.

Yes, the Xeon Gold 5220 paired with the GeForce RTX 4090 can run Hearts of Iron IV smoothly up to 4k achieving around 75 FPS at Ultra quality. Your GPU is 870% above the recommended specs, and your CPU is 862% above the recommended requirements.
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.
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. CPU-limited at: 4k low.
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 Xeon Gold 5220 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.
