Pc Building Simulator

Pc Building Simulator with an AMD Ryzen 7 5700X3D and NVIDIA GeForce RTX 5070 produces a wide performance envelope, but the scaling pattern between resolutions reveals a system that is heavily GPU-bound at high settings. The measured data shows a clear progression: at 1080p Ultra the combo delivers 188.5 FPS, which drops to 120.1 FPS at 1440p and 62.3 FPS at 4K. This represents a 67% reduction from 1080p to 4K at Ultra settings, indicating that the graphics card is the primary limiter. The 4K High preset records 65 FPS, nearly identical to Ultra at 62.3 FPS, while the Low preset at 4K doubles performance to 129.6 FPS, confirming that pixel throughput dominates the workload.

Resolution Scaling

The resolution scaling data shows a consistent pattern of diminishing returns as pixel count increases. From 1080p to 1440p, the High preset drops from 200.9 FPS to 126.4 FPS, a 37% reduction. Moving from 1440p to 4K at High, the frame rate falls to 65 FPS, another 49% drop. The Low preset tells a similar story: 296.5 FPS at 1080p, 249 FPS at 1440p, and 129.6 FPS at 4K. The scaling is not linear—the 4K Low result is still more than double the 4K Ultra result, which suggests that even at the lowest settings, the 4K pixel count imposes a substantial load. The gap between 1440p and 4K is consistently larger than the gap between 1080p and 1440p across all settings, which indicates that the RTX 5070's 672.0 GB/s memory bandwidth and 12 GB frame buffer are being stressed at 4K.

The Medium preset shows intermediate behavior: 262.9 FPS at 1080p, 174.9 FPS at 1440p, and 96.1 FPS at 4K. This pattern—where each resolution step costs roughly 40-50% of the previous frame rate—suggests that the game's rendering pipeline is not scaling efficiently with pixel count at higher settings. The fact that Ultra at 1440p (120.1 FPS) is nearly identical to High at 4K (65 FPS) is misleading; the actual burden is on the GPU's shading units and ROPs. With 80 ROPs and 6144 shading units running at a boost clock of 2512 MHz, the RTX 5070 is capable, but the 4K Ultra workload appears to saturate its 201.0 GPixel/s pixel fill rate.

GPU Role

The NVIDIA GeForce RTX 5070 is the dominant component in this configuration, and the benchmark data confirms it. The GPU's 12 GB of GDDR7 memory on a 192-bit bus delivers 672.0 GB/s of bandwidth, which is ample for 1080p and 1440p but becomes a limiting factor at 4K. The measured FPS at 4K Ultra is 62.3, while the 4K Low preset hits 129.6—this 67 FPS difference is almost entirely due to texture and shading complexity, not memory capacity. The GPU's 48 RT cores and 192 tensor cores are not directly exercised by this simulation title, but the raw FP32 throughput of 30.87 TFLOPS drives the high frame rates at lower resolutions.

Comparing to rivals, the RTX 5070's average benchmark score of 41687 places it 0.6% ahead of the NVIDIA GeForce RTX 3090 (41441) and 0.2% ahead of the AMD Radeon Pro 5300 (41610). This margin is small, but the 5070 achieves it with a 5 nm process node and 31,100 million transistors, whereas the RTX 3090 relies on a larger die. In this game, the 5070's performance at 1080p High (200.9 FPS) shows that the GPU is not the bottleneck at lower resolutions; the CPU can feed it enough frames. At 4K Ultra, however, the 5070's 62.3 FPS indicates that the GPU is working near its limit, as the frame rate drops below the 65 FPS High preset result.

The GPU's memory clock of 1750 MHz (28 Gbps effective) and boost clock of 2512 MHz are consistent with the observed scaling. The 672.0 GB/s bandwidth is sufficient for 1080p and 1440p, but the 4K results (65 FPS High, 62.3 FPS Ultra) show that the memory subsystem is not the primary bottleneck—the shading workload is. The GPU's 80 ROPs and 6144 shading units deliver a pixel rate of 201.0 GPixel/s, which explains why 4K Ultra (62.3 FPS) is only 3% slower than 4K High (65 FPS); the additional quality settings do not significantly increase pixel pressure.

CPU Role

The AMD Ryzen 7 5700X3D plays a supporting role in this title, and the data shows it is rarely the limiting factor. With 8 cores and 16 threads running at a base clock of 3.00 GHz and boost clock of 4.10 GHz, the CPU provides enough throughput to keep the GPU fed at all tested resolutions. The CPU's 96 MB of shared L3 cache is a key asset for simulation games, which often have large data sets. The 3DMark max threads score of 6755 and Cinebench R23 multicore score of 22366 indicate strong multi-threaded performance, but the single-thread score of 3157 (Cinebench R23) is modest, which could matter in CPU-bound scenarios.

The evidence that the CPU is not the bottleneck comes from the FPS scaling. At 1080p Low, the combo achieves 296.5 FPS, which is above the refresh rate of most displays. If the CPU were limiting, the 1080p Low result would be similar to the 1080p Ultra result; instead, it is 57% higher (296.5 vs 188.5). The 1440p Low result of 249 FPS further confirms this, as it is still very high. The CPU's passmark multithread score of 26318 and 3dmark 16 threads score of 6764 suggest that the 5700X3D can handle multiple background tasks, but this game's simulation logic likely runs on fewer threads. The passmark single thread score of 2970 is the more relevant metric, and it is adequate for this title.

The CPU's nearest rivals show a tight cluster: the Intel Core i7-1360P is 0.2% ahead, the AMD Ryzen 5 7600X3D is 0.3% ahead, and the Intel Core i5-11600 is 0.5% ahead. The AMD Ryzen AI Max 385 is 0.6% behind. This grouping indicates that the 5700X3D's performance is typical for its class, and the 82nd percentile ranking among all CPUs confirms it is a solid mid-range option. In this game, the CPU's 51.2 GB/s memory bandwidth on dual-channel DDR4 is sufficient, as the GPU does the heavy lifting. The 105 W TDP and 7 nm process node (TSMC) keep thermals manageable, but the lack of a multiplier unlock means no overclocking headroom, which is irrelevant given the GPU-bound nature of the results.

Settings Recommendations

For the best experience based on the measured rows, the data clearly favors 1440p or 1080p over 4K. At 1080p, the Ultra preset delivers 188.5 FPS, which is more than enough for any display, and the Medium preset (262.9 FPS) offers a smoother experience with marginal visual compromise. The Low preset at 1080p (296.5 FPS) is unnecessary unless targeting extreme refresh rates. For 1440p, the High preset (126.4 FPS) is the sweet spot—it provides a 5% improvement over Ultra (120.1 FPS) with barely any visual difference, and it keeps the frame rate well above 60 FPS. The Medium preset at 1440p (174.9 FPS) is a valid alternative for users who prefer higher frame rates over detail.

At 4K, the situation is different. The Ultra preset (62.3 FPS) and High preset (65 FPS) are nearly identical, and both hover around the 60 FPS threshold. The Medium preset (96.1 FPS) offers a substantial improvement, making it the best 4K option for smooth gameplay. The Low preset (129.6 FPS) is the only 4K setting that approaches high-refresh territory, but it sacrifices significant visual fidelity. Given that the GPU is the limiting factor at 4K, users should either accept 60 FPS at High/Ultra or drop to Medium for a 48% frame rate increase. The ranking data (390 out of 1769) suggests this combo is well-suited for 1080p and 1440p gaming, with 4K being a secondary consideration. For most users, the 1440p High preset (126.4 FPS) is the recommended default, as it balances visual quality with a frame rate that exceeds 120 FPS on standard monitors.
