Pc Building Simulator

Pc Building Simulator is a simulation title that tasks players with assembling and troubleshooting PCs, and its performance profile with the AMD Ryzen 9 5900X and NVIDIA GeForce RTX 3070 reveals a system that scales predictably with resolution and settings. The measured data shows this combo sits at rank 1569 out of 3723 tested configurations, placing it in the upper-middle tier for this game. The 12-core Ryzen 9 5900X, with its Zen 3 architecture and boost clock of 4.80 GHz, pairs with the 8 GB GDDR6 RTX 3070 to deliver frame rates that range from highly competitive at 1080p to merely playable at 4K Ultra.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep, which tells a clear story about what component is doing the heavy lifting in Pc Building Simulator. At 1080p with Low settings, the system produces 302 FPS, but at 4K Low, that number falls to 100 FPS — a 67% reduction. This dramatic scaling indicates that the RTX 3070's GPU pipeline becomes the limiting factor as pixel count rises, while the Ryzen 9 5900X has ample headroom to feed frames at lower resolutions.

Moving from 1440p to 4K shows an even more pronounced cliff. At 1440p High, the average is 95 FPS, which drops to 50 FPS at 4K High — a 47% loss. The trend continues across all settings: 1440p Medium delivers 135 FPS versus 71 FPS at 4K Medium, and 1440p Ultra yields 91 FPS compared to 47 FPS at 4K Ultra. This consistent halving of performance when doubling the pixel count from 1440p to 4K points directly at the GPU's 8 GB memory buffer and its 448.0 GB/s bandwidth being saturated by the higher resolution workloads.

The data suggests that Pc Building Simulator is not particularly CPU-bound at any resolution. The Ryzen 9 5900X, with its 24 threads and 64 MB of L3 cache, can push the RTX 3070 to its limits at 1080p, where the GPU's 20.31 TFLOPS of FP32 compute is the bottleneck. At 4K, the gap between Low (100 FPS) and Ultra (47 FPS) settings further confirms that the GPU's shading units, texture mapping units, and raster operation units are the primary constraint, not the processor's capabilities.

FAQ

Q: Can this system handle 4K gaming in Pc Building Simulator?

A: Yes, but only at lower settings. At 4K Medium, the combo averages 71 FPS with a minimum of 60 FPS and maximum of 81 FPS, which is playable. At 4K High, the average drops to 50 FPS, and at Ultra it falls to 47 FPS, so you will need to compromise on visual fidelity to maintain smooth frame rates at this resolution.

Q: What is the best resolution for this CPU and GPU combo?

A: The sweet spot is 1440p. At this resolution, High settings produce 95 FPS, Medium yields 135 FPS, and even Ultra manages 91 FPS. This gives you the visual quality of higher resolutions while staying well above the 60 FPS threshold for smooth gameplay.

Q: How does the RTX 3070 compare to its closest rivals in this game?

A: The RTX 3070 has an average benchmark score of 17208, which is 0.7% higher than the AMD Radeon RX 7600 XT (17083) and 1% higher than the NVIDIA GeForce GTX 690 (17037). It trails the NVIDIA Tesla K40c by 1.5%, but that is a compute-oriented card, not a gaming GPU.

Q: Is the Ryzen 9 5900X overkill for this game?

A: The data suggests yes. The CPU's 3DMark max-thread score of 10075 and Cinebench R23 multi-core score of 16262 are far beyond what Pc Building Simulator requires, as evidenced by the fact that frame rates scale almost entirely with GPU load. The processor sits at the 87th percentile among all CPUs, but this game does not appear to leverage its full multi-threading potential.

Q: What frame rate can I expect at 1080p with Ultra settings?

A: The measured average is 144 FPS, which is excellent for a simulation game. This is only 2.3% lower than the 1080p High preset's 151 FPS, indicating that Ultra settings are very playable at this resolution without a significant performance penalty.

Q: Does the 8 GB VRAM on the RTX 3070 cause issues at 4K?

A: The benchmark results indicate that 4K Ultra averages 47 FPS, which is low but not a slide show. The 8 GB GDDR6 memory with 256-bit bus width and 448.0 GB/s bandwidth appears sufficient to avoid stuttering, as evidenced by the 4K Medium minimum of 60 FPS, but the card's compute limits are the real constraint at this resolution.

GPU Role

The NVIDIA GeForce RTX 3070 is the dominant component in this pairing for Pc Building Simulator. Its Ampere architecture, built on Samsung's 8 nm process, contains 17,400 million transistors across a 392 mm² die. The card's 5888 shading units, 184 texture mapping units, and 96 raster operation units process the game's visuals with a base clock of 1500 MHz and boost clock of 1725 MHz. These specifications translate to a pixel rate of 165.6 GPixel/s and a texture rate of 317.4 GTexel/s, which directly influence how fast the game can render its 3D scenes.

The GPU's memory subsystem is critical for higher resolutions. The 8 GB of GDDR6 memory operates at 1750 MHz, or 14 Gbps effective, across a 256-bit bus. This configuration yields a bandwidth of 448.0 GB/s, which is sufficient for 1080p and 1440p gaming but becomes strained at 4K. The measured data supports this: at 4K, the frame rate drops to 47-100 FPS depending on settings, while at 1440p it ranges from 91-191 FPS. The 4K Medium results show a minimum of 60 FPS and maximum of 81 FPS, suggesting the memory pipeline is holding steady but the compute units are maxed out.

In terms of raw compute, the RTX 3070 delivers 20.31 TFLOPS of FP32 and FP16 performance. The card also includes 46 RT cores and 184 tensor cores, though Pc Building Simulator likely does not utilize ray tracing or DLSS features heavily. The GPU's PassMark G3D score of 22214 places it at the 61st percentile among all GPUs, and its average benchmark score of 17208 puts it in close competition with the AMD Radeon RX 7600 XT (17083) and NVIDIA GeForce GTX 690 (17037). The RTX 3070's 0.7% and 1% advantages over these rivals are slim, indicating that the card is well-positioned but not dominant in its class.

Measured FPS Breakdown

The measured frame rates provide a comprehensive picture of performance across three resolutions and four settings. At 1920x1080, the system delivers exceptional frame rates: Low settings average 302 FPS, Medium averages 214 FPS with a minimum of 182 FPS and maximum of 246 FPS, High averages 151 FPS, and Ultra averages 144 FPS. These numbers indicate that at 1080p, the Ryzen 9 5900X is capable of pushing the RTX 3070 to very high output, with the GPU becoming the limiting factor above 300 FPS.

At 2560x1440, performance remains strong but shows the expected drop. Low settings average 191 FPS, which is still excellent for competitive play. Medium settings average 135 FPS with a minimum of 115 FPS and maximum of 155 FPS, providing a smooth experience with room to spare. High settings average 95 FPS, and Ultra averages 91 FPS. The gap between High and Ultra at 1440p is only 4 FPS, suggesting that the Ultra preset does not add significant visual complexity that would cripple the GPU.

At 3840x2160, the system starts to struggle with higher settings. Low settings average 100 FPS, which is playable. Medium settings average 71 FPS with a minimum of 60 FPS and maximum of 81 FPS, hitting the playability threshold. High settings drop to 50 FPS, and Ultra falls to 47 FPS. The 4K results show a clear trend: the RTX 3070 simply does not have enough compute power to maintain high frame rates at this resolution with High or Ultra presets. Interestingly, the jump from Low to Medium at 4K costs 29 FPS (100 to 71), while the jump from Medium to High costs 21 FPS (71 to 50), indicating diminishing returns as settings increase.

CPU Role

The AMD Ryzen 9 5900X is a high-end desktop processor that provides more than enough compute power for Pc Building Simulator. With 12 cores and 24 threads based on the Zen 3 architecture, codenamed Vermeer, the CPU operates at a base clock of 3.70 GHz and a boost clock of 4.80 GHz. Its 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 64 MB of shared L3 cache help feed the GPU with data efficiently. The processor's 7 nm TSMC fabrication process houses 8,300 million transistors across a dual-die design, each die measuring 74 mm².

The CPU's benchmark scores demonstrate its capability. In Cinebench R23, it scores 16262 multi-core and 1527 single-core. Geekbench results show 14118 multi-core and 2083 single-core. The PassMark multi-thread score is 39002, with a single-thread score of 3469. These numbers, combined with a 3DMark max-thread score of 10075, place the Ryzen 9 5900X at the 87th percentile among all CPUs. Its nearest rivals include the Intel Core Ultra 7 366H (0.3% faster), Intel Core Ultra 7 356H (0.4% faster), and AMD Ryzen AI 5 PRO 440 (0.4% faster), while it edges out the Intel Core i7-14650HX by 0.5%.

In Pc Building Simulator, the CPU's role is primarily to simulate the game's logic and feed the GPU with draw calls. The frame rate data indicates that the Ryzen 9 5900X is not a bottleneck at any resolution. At 1080p Low, the system achieves 302 FPS, which is near the practical limit for most displays and suggests the GPU is the limiting factor. Even at 4K, where the GPU is clearly stressed, the CPU's 24 threads and high boost clock ensure that the game logic does not introduce stutter or frame pacing issues. The processor's dual-channel DDR4 memory support and 51.2 GB/s bandwidth are sufficient for this simulation title.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on your display resolution and performance targets. For 1080p users, the Ultra preset provides the best experience, averaging 144 FPS with no minimum frame rate data recorded. This is only 7 FPS lower than High (151 FPS) and 70 FPS lower than Low (302 FPS), but the visual fidelity gains from Ultra are worth the minimal performance hit. If you have a 144 Hz monitor, Ultra will keep you comfortably above the refresh rate.

For 1440p, the Medium preset offers the best balance of visual quality and performance. It averages 135 FPS with a minimum of 115 FPS and maximum of 155 FPS, ensuring no drops below 60 FPS. High settings at 95 FPS are also viable, but the 40 FPS gap between Medium and High suggests that Medium provides a significantly smoother experience. Ultra at 91 FPS is playable but leaves little headroom for demanding scenes, so Medium is the safer choice for consistent frame times.

For 4K users, the Medium preset is the only recommended option. It averages 71 FPS with a minimum of 60 FPS and maximum of 81 FPS, which meets the standard for smooth gameplay. Low settings at 100 FPS are faster but sacrifice too much visual quality for a simulation game where you are examining PC components. High at 50 FPS and Ultra at 47 FPS are below the 60 FPS threshold and may cause noticeable judder during camera movements. If you insist on High or Ultra at 4K, consider lowering the resolution to 1440p, where the same settings produce 95 FPS and 91 FPS respectively. The data clearly shows that Medium at 1440p or 4K is the performance sweet spot for this CPU and GPU combination.
