Pc Building Simulator

Pc Building Simulator, a simulation title from 2019, responds dramatically to both resolution and quality settings when paired with the AMD Ryzen 7 5800X3D and NVIDIA GeForce RTX 4070. The measured data reveals a system that is overwhelmingly capable at 1080p, exceptionally strong at 1440p, and only at 4K does the combination begin to show its limits, specifically under the highest preset. This analysis walks through the recorded frame rates, contextualizes the performance against the measured combo pool, and examines the specific contributions of the CPU and GPU based on the provided specifications.

Resolution Scaling

The frame rate cost of moving from 1080p to 4K is substantial across all settings, but the shape of that scaling curve changes depending on the preset. At Low settings, the average frame rate falls from 325.6 FPS at 1920x1080 to 119.7 FPS at 3840x2160, a reduction of roughly 63%. This severe drop indicates that even at the lowest quality, the pixel throughput demand at 4K is enormous, shifting the bottleneck firmly onto the GPU's rendering pipeline. At Medium settings, the scaling is similar in magnitude, with the 1080p score of 261.1 FPS dropping to 87.9 FPS at 4K.

The transition from High to Ultra reveals a different story. At 2560x1440, the High preset delivers 114.1 FPS, while Ultra delivers 112.0 FPS—a mere 2.1 FPS difference. At 1920x1080, the gap between High (183.8 FPS) and Ultra (172.3 FPS) is also relatively small, at 11.5 FPS. However, at 3840x2160, the difference widens to 2.7 FPS (60.4 vs 57.7), showing that Ultra's extra overhead becomes more punishing as resolution increases. The data suggests that the RTX 4070's 12 GB frame buffer and 504.2 GB/s memory bandwidth are sufficient for High settings at 4K, but the Ultra preset's additional effects push the rendering time per frame beyond what the card can comfortably sustain.

The most telling metric for identifying the limiting component is the 1080p to 1440p scaling at Low settings. Here, the frame rate drops from 325.6 FPS to 228.9 FPS. This 96.7 FPS drop is proportionally smaller than the 1440p to 4K drop (228.9 FPS to 119.7 FPS, a 109.2 FPS difference). This pattern—where the absolute FPS loss accelerates as resolution increases—is characteristic of a GPU-bound scenario. The CPU, an 8-core, 16-thread Zen 3 part, is clearly not the constraint at 1080p, as it is able to feed the GPU enough data to produce over 300 FPS.

Settings Recommendations

Based solely on the measured average FPS, the optimal preset depends heavily on the target resolution and refresh rate. For 1080p displays, the High preset at 183.8 FPS offers a superb balance, but even the Ultra preset at 172.3 FPS is well above the 144 Hz threshold, making it a viable choice for maximum visual fidelity. The Low preset's 325.6 FPS is excessive for most monitors and sacrifices too much visual quality for a negligible practical gain.

At 2560x1440, the High preset (114.1 FPS) is the clear sweet spot, providing a fluid experience that is just above the 110 FPS mark. The Ultra preset (112.0 FPS) is nearly identical in performance, meaning users can enable the highest settings with almost no frame rate penalty. The Medium preset (162.0 FPS) is also excellent, but the data shows that High and Ultra are achievable without significant cost, making Medium an unnecessary compromise.

For 4K gaming, the situation is more nuanced. The High preset (60.4 FPS) is the only setting that consistently clears the 60 FPS bar, making it the recommended choice for a smooth, console-like experience. The Medium preset (87.9 FPS) is also playable and offers a higher refresh rate, but the Ultra preset (57.7 FPS) dips below 60 FPS, which may be noticeable in a simulation title where UI responsiveness is key. The Low preset (119.7 FPS) is technically the fastest, but its visual downgrade is drastic compared to the modest frame rate gain over Medium. Therefore, for 4K, High is the best compromise between visual quality and the essential 60 FPS baseline.

How This Combo Ranks

Within the database of measured combos, this pairing of the AMD Ryzen 7 5800X3D and NVIDIA GeForce RTX 4070 holds a rank of 487 out of 1769 tested combinations. This places it in the top 27.5% of all systems tested for this game, a strong showing that confirms its high-end positioning. The rank reflects a system that is not at the absolute peak of the charts but is clearly in the upper quartile, outperforming a majority of the other hardware pairings.

When looking at the individual component performance, the CPU's percentile rank of 83 against all CPUs is higher than the GPU's percentile rank of 81 against all GPUs. This suggests that the Ryzen 7 5800X3D is a slightly more exceptional part relative to its peers than the RTX 4070 is relative to its own. The combo's overall rank of 487, however, is not simply an average of these two percentiles. It is a direct result of their interaction in this specific game, which is heavily GPU-bound at higher resolutions, as seen in the Resolution Scaling section. The CPU's strength ensures that it never becomes the limiting factor, allowing the GPU to fully express its potential.

Measured FPS Breakdown

The complete measured data set provides a clear matrix of performance. At 1920x1080, the averages are: Low at 325.6 FPS, Medium at 261.1 FPS, High at 183.8 FPS, and Ultra at 172.3 FPS. The step from Low to Medium is a 64.5 FPS drop, while the step from Medium to High is a larger 77.3 FPS drop. The final step to Ultra is relatively small, at 11.5 FPS, indicating diminishing returns on the highest preset at this resolution.

Moving to 2560x1440, the averages are: Low at 228.9 FPS, Medium at 162.0 FPS, High at 114.1 FPS, and Ultra at 112.0 FPS. Here, the gap between Medium and High (47.9 FPS) is significantly larger than the gap between High and Ultra (2.1 FPS). At 3840x2160, the averages are: Low at 119.7 FPS, Medium at 87.9 FPS, High at 60.4 FPS, and Ultra at 57.7 FPS. The drop from Medium to High (27.5 FPS) is the most severe step, highlighting the cost of enabling higher-quality textures and shading at 4K. The difference between Low and Medium (31.8 FPS) is also notable, showing that even mid-tier settings have a significant impact at this resolution.

GPU Role

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture using a 5 nm process, featuring 5,888 shading units and 184 texture mapping units. Its 12 GB of GDDR6X memory on a 192-bit bus provides a bandwidth of 504.2 GB/s. The measured FPS data shows that this memory configuration is the key differentiator between High and Ultra presets at 4K. The card's boost clock of 2475 MHz and FP32 performance of 29.15 TFLOPS are more than adequate for the computational demands of this simulation, as evidenced by the 325.6 FPS score at 1080p Low.

The GPU's average benchmark score of 37,283 places it in the 81st percentile of all GPUs. Its nearest rival in the database is the AMD Radeon RX Vega 56, which scores 37,507, a mere 0.6% higher. This indicates that the RTX 4070's raw compute performance is closely matched by an older competitor, but the measured FPS in this game suggests that the RTX 4070's newer architecture and memory subsystem are better utilized, as it achieves a rank of 487 in the combo list. The performance at 4K High (60.4 FPS) versus 4K Ultra (57.7 FPS) shows a 4.5% performance penalty for the Ultra preset, suggesting that the 12 GB VRAM is sufficient but the additional memory pressure and compute load of Ultra settings push the card to its limit.

CPU Role

The AMD Ryzen 7 5800X3D is a Zen 3 (Vermeer) part with 8 cores and 16 threads, capable of boosting up to 4.50 GHz. Its defining feature is the large 96 MB of shared L3 cache, which is a critical asset for simulation games that often have complex, cache-dependent logic. The CPU's benchmark results are strong, with a Cinebench R23 multi-core score of 24,063 and a single-core score of 3,397. Its average benchmark score of 26,574 puts it in the 83rd percentile, with its nearest rival being the AMD EPYC 8024P, which scores 26,555, a 0.1% difference.

In the context of Pc Building Simulator, the CPU's role is to prepare the frame data and manage the game's simulation logic. The data shows that it excels at this task. At 1080p Low, the system produces 325.6 FPS, which is a clear indication that the CPU is not a bottleneck, as it can maintain a high frame rate even when the GPU's workload is relatively light. The 3dmark 16-thread score of 7,299 and the Passmark multi-thread score of 28,309 demonstrate robust multi-threading capability. However, the game's frame rate scaling with resolution indicates that beyond 1080p, the GPU becomes the primary limiter. The CPU's high single-thread performance (Passmark single-thread score of 3,234) ensures that it can keep up with the GPU's frame generation at lower resolutions, but its impact on the final FPS at 4K is minimal, as the GPU is fully saturated.
