Pc Building Simulator

Opening Paragraph

Pc Building Simulator presents an unusual benchmark scenario: a simulation title where the act of assembling and configuring hardware is the gameplay, yet the in-engine rendering still places a measurable load on the GPU and CPU. The data for this combination—an AMD Ryzen 5 5600G paired with an NVIDIA GeForce RTX 4080—reveals a system that is overwhelmingly GPU-bound at higher resolutions, but which also exposes the CPU's limitations at 1080p. The measured FPS across the board shows that this pairing delivers playable performance in nearly every configuration, but the scaling patterns offer clear guidance for optimizing the experience. This analysis breaks down the measured rows to explain exactly what the numbers mean for a builder using this specific CPU and GPU combo, without speculation beyond the provided facts.

Resolution Scaling

The FPS data shows a steep and predictable decline as resolution increases, which is the classic signature of a GPU-limited scenario at higher settings. At 1080p with Low settings, the combo delivers 281 FPS. Moving to 1440p Low drops that to 193 FPS—a 31% reduction in frame rate, which aligns with the roughly 1.78x increase in pixel count, though the GPU still has headroom. At 4K Low, the average falls to 103 FPS, which is a 63% drop from the 1080p figure, confirming that the RTX 4080 is doing progressively heavier lifting.

The scaling pattern changes character when settings are raised. At Ultra settings, the frame rate goes from 126 FPS at 1080p to 81 FPS at 1440p (a 36% drop) and then to 43 FPS at 4K (a 47% drop from 1440p, or 66% from 1080p). This steeper falloff at higher settings indicates that the GPU's shading and memory bandwidth are the limiting factors, not the CPU. The 4K Ultra result of 43 FPS is the only sub-60 FPS measurement in the entire dataset, which strongly suggests that the RTX 4080 is being pushed to its limits by the combination of pixel count and render complexity.

The limiting component shifts clearly between resolutions. At 1080p, the Ryzen 5 5600G's six cores and 12 threads can produce 281 FPS on Low, but the gap between Low and Ultra at that resolution (281 vs 126 FPS) is a 55% performance swing, indicating the GPU is still the primary constraint even at the lowest settings. At 4K, the GPU is unquestionably the bottleneck: the difference between Low and Ultra is 103 vs 43 FPS, a 58% swing, while the CPU's role diminishes because the frame time budget is so much larger. The data shows that this combo is most balanced at 1440p, where the CPU can feed the GPU well enough to hit 193 FPS on Low and 81 FPS on Ultra.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this pairing, and its specifications explain the measured results. With 16 GB of GDDR6X memory on a 256-bit bus, the card has a bandwidth of 716.8 GB/s, which is ample for 4K textures and high-detail rendering. The boost clock of 2505 MHz, paired with 9728 shading units, drives the raw compute throughput of 48.74 TFLOPS FP32, which translates into the high frame rates seen at 1080p and 1440p.

The GPU's 76 RT cores and 304 tensor cores are present, though Pc Building Simulator's rendering workload in these measurements does not appear to stress ray tracing or DLSS specifically, as no such settings are listed in the measured rows. The card's memory capacity of 16 GB is well above what any of these settings would require, so VRAM is not a limiting factor in any measured configuration. The pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are the specifications that correlate most directly with the 4K performance: the card can fill pixels quickly, but the 43 FPS at 4K Ultra suggests that the shading complexity of the Ultra preset is the bottleneck, not memory bandwidth.

The RTX 4080's percentile rank of 86 among all GPUs, with an average benchmark score of 54247, places it near the top of the stack. Its nearest rival, the RTX 4080 SUPER, scores 54209—a delta of only 0.1%—which means the performance difference between the two is negligible in synthetic tests. This context is useful: the 4080 in this combo is performing as expected for its class, and the FPS numbers reflect a high-end GPU that is not being held back by the CPU except at the lowest resolution and settings.

Settings Recommendations

Based on the measured rows, the Medium preset offers the best balance of visual quality and performance across all three resolutions. At 1080p, Medium delivers 227 FPS with a minimum of 193 FPS, which provides a wide safety margin above any refresh rate. At 1440p, Medium averages 145 FPS with a minimum of 123 FPS, still comfortably above 120 FPS for high-refresh monitors. At 4K, Medium yields 77 FPS with a minimum of 66 FPS, which is the only setting at 4K that stays above the 60 FPS threshold while also offering better visuals than Low.

The Ultra preset is not recommended for this game and CPU combo, as it produces 43 FPS at 4K, which is below the playable threshold for most users. Even at 1440p, Ultra drops to 81 FPS, which is acceptable but not ideal if the user wants to maintain a consistent 100+ FPS experience. High settings, meanwhile, sit between Medium and Ultra: 172 FPS at 1080p, 110 FPS at 1440p, and 58 FPS at 4K. The 4K High result of 58 FPS is just under the 60 FPS mark, making it a marginal choice for 4K, while Medium's 77 FPS at 4K is a better option.

For a 1080p or 1440p gamer, the Low preset is unnecessary—281 FPS and 193 FPS respectively—since Medium provides a substantial visual upgrade with only a 19-25% FPS cost. The data suggests that Medium is the sweet spot for this title, and any user with a 120 Hz or 144 Hz monitor should target Medium at 1440p for the best combination of smoothness and fidelity.

Measured FPS Breakdown

At 1920x1080, the full range of settings shows the GPU's headroom. Low averages 281 FPS, Medium averages 227 FPS with a minimum of 193 FPS and a maximum of 261 FPS, High averages 172 FPS, and Ultra averages 126 FPS. The spread from Low to Ultra is 155 FPS, which means the user has complete control over the visual-to-performance tradeoff. The minimum FPS of 193 at Medium confirms that even in demanding scenes, the frame rate does not dip below 193 FPS, indicating consistent performance.

At 2560x1440, the pattern continues but with lower absolute numbers. Low averages 193 FPS, Medium averages 145 FPS with a minimum of 123 FPS and a maximum of 167 FPS, High averages 110 FPS, and Ultra averages 81 FPS. The gap between Low and Ultra narrows to 112 FPS, showing that the GPU is becoming more of a constraint. The Medium minimum of 123 FPS is still above the 120 FPS threshold, which is a strong result for 1440p gaming.

At 3840x2160, performance drops significantly. Low averages 103 FPS, Medium averages 77 FPS with a minimum of 66 FPS and a maximum of 89 FPS, High averages 58 FPS, and Ultra averages 43 FPS. The Medium setting at 4K is the only one that maintains an average above 60 FPS, and its minimum of 66 FPS means even the worst-case frame time is playable. High at 4K is borderline at 58 FPS, and Ultra is not recommended at 43 FPS. The data shows a clear cliff between Medium and High at 4K, with a 19 FPS drop, which is larger than the 15 FPS drop between Low and Medium at that resolution.

Q: Should a user prioritize a high refresh rate monitor or a 4K monitor with this setup?

A: The data supports a 1440p high-refresh monitor, as the Medium preset delivers 145 FPS with a minimum of 123 FPS. A 4K monitor is viable only at Medium settings (77 FPS average), which is still smooth but does not take full advantage of the GPU's potential.

CPU Role

The AMD Ryzen 5 5600G is a 6-core, 12-thread processor based on the Zen 3 architecture, with a base clock of 3.90 GHz and a boost clock of 4.40 GHz. Its 16 MB of L3 cache and 7 nm process node are typical for the 5000 series, and the chip's 65 W TDP indicates it is a low-power part. In synthetic benchmarks, the CPU scores 10551 in Cinebench R23 multi-core and 1409 in single-core, with a PassMark multi-thread score of 19717 and a single-thread score of 3177. The percentile rank of 74 among all CPUs, with an average benchmark score of 21088, places it in the upper-middle tier, just above the Intel Core i3-1220P (21066, +0.1%) and slightly below the AMD Ryzen 5 7530U (21133, -0.2%).

In the context of Pc Building Simulator, the CPU's role is secondary to the GPU, but the measured FPS reveals its influence at lower resolutions. At 1080p Low, the 281 FPS result suggests the CPU is capable of driving high frame rates, but the fact that the same CPU with the same GPU at 1080p Ultra only reaches 126 FPS indicates that the render workload is still GPU-bound. The CPU's 12 threads are more than sufficient for a simulation title like this, which typically does not scale heavily beyond a few cores.

The data shows that the CPU is not a bottleneck at 4K, where the GPU's 43 FPS at Ultra is clearly the limiting factor. Even at 4K Low, the 103 FPS result is far below the CPU's theoretical capability, as evidenced by its 3DMark max-thread score of 5455. The pairing is well-balanced for this game at 1440p Medium, where the CPU can maintain a minimum of 123 FPS, indicating it is feeding the GPU adequately. A weaker CPU might drag down those minimum FPS numbers, but the 5600G's performance in this dataset shows no such issue, as the minimum FPS at 1440p Medium is 123 FPS, which is a healthy margin above the average of 145 FPS.
