Pc Building Simulator

Pc Building Simulator, a simulation title that tasks players with assembling and benchmarking virtual hardware, presents an interesting case study when paired with an AMD Ryzen 9 7900X and an AMD Radeon RX 570. The combination of a top-tier modern CPU with an end-of-life GPU from 2017 creates a significant performance bottleneck, but the measured FPS data reveals exactly where that bottleneck lies and how it scales with resolution and settings. This analysis explores the measured frames per second across three resolutions and four quality presets to understand the interplay between the 12-core processor and the 4 GB graphics card.

Resolution Scaling

The most immediate observation from the data is the dramatic impact of resolution on frame rates. At 1920x1080, the system achieves a playable 56.7 FPS on High settings, but this figure plummets to 34.7 FPS at 2560x1440 and further to 19.1 FPS at 3840x2160. This is a clear indicator that the rendering workload is scaling directly with pixel count, placing the burden squarely on the GPU. The 4K results are particularly telling, with even the Low preset only managing 36.5 FPS, which is below the 1080p High setting's performance. This suggests that at 4K, the RX 570 is entirely overwhelmed, and the CPU's substantial compute resources are largely idle, waiting for the graphics card to catch up.

The delta between settings also widens at higher resolutions, which is a classic sign of GPU limitation. At 1080p, the difference between Low and Ultra is 58.2 FPS (110.3 vs 52.1), while at 4K, that same gap shrinks to 18.9 FPS (36.5 vs 17.6). This compression of performance scaling at higher resolutions indicates that the GPU is hitting its absolute ceiling, and further increasing the graphical load yields diminishing returns in FPS loss because the card is already saturated. The data implies that for this specific combo, 1080p is the only resolution where the CPU can meaningfully contribute to frame rate headroom, while 1440p and 4K are strictly GPU-bound scenarios.

Settings Recommendations

For the best experience per the measured rows, the Medium preset at 1920x1080 emerges as the optimal balance. It delivers 78.3 FPS, which is a significant 21.6 FPS improvement over High and 26.2 FPS over Ultra. This suggests that the jump from Medium to High incurs a heavy performance cost for what is likely a marginal visual gain in a simulation game where UI elements and menu navigation are frequent. The Low preset at 1080p does offer 110.3 FPS, but this is likely to be visually sparse, and the 32 FPS advantage over Medium may not be worth the graphical fidelity sacrifice.

At 2560x1440, the situation changes. The Low preset is the only one that maintains a playable frame rate above 60, hitting 65.8 FPS. The Medium preset drops to 49.2 FPS, which is still workable but may not feel smooth in a game that relies on precise clicking and dragging of components. High and Ultra at 1440p, at 34.7 and 31.2 FPS respectively, are too slow for a responsive experience. For 4K, none of the presets are truly playable, with the fastest option, Low, only reaching 36.5 FPS. The data suggests that users should stick to 1080p Medium for a smooth experience or be prepared to tolerate sub-60 FPS at higher resolutions.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor from the 7000 series with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. Its benchmark scores are formidable, with a Cinebench R23 multicore score of 43695 and a single-core score of 6168. In Pc Building Simulator, which is not a demanding title, this CPU is almost certainly not the limiting factor. The data supports this, as the FPS drops are entirely consistent with GPU-bound behavior.

The CPU's role here is to ensure that the simulation logic, physics calculations, and UI interactions are handled without any frame-time stutter. With a PassMark multithread score of 51406 and a 3DMark max threads score of 12536, the 7900X has enormous headroom. The nearest rivals in the CPU benchmark database, such as the Intel Core Ultra 5 235 and AMD Ryzen 9 5900XT, score within 0.8% of the 7900X, indicating that any of these top-tier chips would perform identically in this game at these settings. The bottleneck is entirely on the graphics side, meaning the CPU's vast processing power is effectively wasted in this specific configuration.

How This Combo Ranks

The combination of the Ryzen 9 7900X and RX 570 ranks 1682 out of 1769 tested combos in Pc Building Simulator. This places it in the bottom 5% of all configurations, which is a stark illustration of how a powerful CPU cannot compensate for a weak GPU. The 87-combo gap to the top of the list is a massive chasm, and it is almost entirely due to the RX 570's age and limited capabilities.

This ranking is expected, given the GPU's performance. The RX 570's average benchmark score of 30158 places it near the NVIDIA GeForce RTX 5060 and AMD Radeon RX 7700 XT in the synthetic benchmark database, but those GPUs have far more modern features and memory bandwidth. In a game like Pc Building Simulator, the ranking reflects that the system is severely imbalanced. Users would see a dramatic improvement in both ranking and playability by pairing the 7900X with a more modern graphics card, as the current combo results in a poor experience despite having one of the best CPUs on the market.

FAQ

Q: Is the AMD Ryzen 9 7900X holding back the AMD Radeon RX 570 in this game?

A: No. The benchmark data shows a classic GPU bottleneck. FPS scales heavily with resolution and settings, which is a characteristic of a graphics-limited scenario. The CPU's massive compute headroom (Cinebench R23 multicore score of 43695) is not the constraint, as the FPS drops are entirely consistent with the GPU's rendering load.

Q: What is the best setting for a smooth 60 FPS experience?

A: The only measured configuration that achieves above 60 FPS is the Low preset at 1920x1080, which hits 110.3 FPS. However, the Medium preset at 1080p, with 78.3 FPS, is the highest quality setting that still comfortably exceeds 60 FPS, making it the best balance of visual quality and performance.

Q: Can this system run the game at 4K?

A: Technically, yes, but the experience is poor. The highest average FPS at 3840x2160 is 36.5 FPS on Low settings, which drops to 17.6 FPS on Ultra. None of the presets at 4K achieve a playable frame rate for a smooth experience.

Q: Why is the performance gap between Low and Ultra smaller at 4K than at 1080p?

A: At 1080p, the GPU has enough headroom to show a large gap between presets (110.3 FPS Low vs 52.1 FPS Ultra). At 4K, the GPU is already saturated at the lowest settings (36.5 FPS), so increasing to Ultra only brings it down to 17.6 FPS. The absolute performance ceiling is reached, compressing the differences.

Q: How does this combo rank against other tested systems?

A: This pairing of CPU and GPU ranks 1682 out of 1769 total combos in Pc Building Simulator. This places it in the lowest 5% of all tested configurations, indicating a severely unbalanced system where the GPU is the primary limitation.

Q: Does the CPU's single-thread performance matter for this game?

A: While the Ryzen 9 7900X has an excellent single-thread score of 6168 in Cinebench R23, the data does not show it as a limiting factor. The FPS is consistently tied to resolution and settings, which are GPU workloads. A slower CPU would likely still produce the same FPS in this specific game with this GPU.

Measured FPS Breakdown

The following table details the exact average frames per second recorded for each resolution and settings combination.

| Resolution | Settings | Avg FPS |

|---|---|---|

| 1920x1080 | Low | 110.3 |

| 1920x1080 | Medium | 78.3 |

| 1920x1080 | High | 56.7 |

| 1920x1080 | Ultra | 52.1 |

| 2560x1440 | Low | 65.8 |

| 2560x1440 | Medium | 49.2 |

| 2560x1440 | High | 34.7 |

| 2560x1440 | Ultra | 31.2 |

| 3840x2160 | Low | 36.5 |

| 3840x2160 | Medium | 23.3 |

| 3840x2160 | High | 19.1 |

| 3840x2160 | Ultra | 17.6 |

The data shows a clear pattern: 1080p is the only resolution where the system can consistently deliver high frame rates. The step from 1080p to 1440p costs roughly 40-50% of the frame rate across all settings, and the step to 4K is another significant drop.

GPU Role

The AMD Radeon RX 570 is the clear bottleneck in this configuration. With 4 GB of GDDR5 memory on a 256-bit bus, it offers 224.0 GB/s of bandwidth. Its base clock is 1168 MHz with a boost clock of 1244 MHz, and it has 2048 shading units. These specs, while respectable for 2017, are woefully insufficient for modern gaming at high resolutions. The GPU's 74th percentile ranking among all GPUs and its average benchmark score of 30158 are far below what the Ryzen 9 7900X can feed it.

The measured FPS at 4K, where even Low settings only yield 36.5 FPS, directly reflects the GPU's memory and compute limitations. The 4 GB VRAM is likely a major constraint at Ultra settings, as texture data might be spilling to system memory. The performance delta between Low and Ultra at 1080p (58.2 FPS) shows the GPU's scaling capability, but the absolute numbers are still low. The data implies that the RX 570 is only suitable for 1080p gaming on this title, with any higher resolution resulting in a suboptimal experience. Its 150 W TDP and lack of modern features like hardware ray tracing further cement its status as the limiting component in this pairing.
