# Pc Building Simulator — AMD Ryzen 7 5800XT + NVIDIA GeForce RTX 4080 SUPER

Pc Building Simulator, a simulation title released in 2019, presents an unusual workload profile: it is not a graphically demanding AAA shooter but a menu-heavy, system-building sandbox where frame rates often exceed display refresh rates. The benchmark data for the AMD Ryzen 7 5800XT paired with the NVIDIA GeForce RTX 4080 SUPER shows a configuration that is overwhelmingly GPU-bound at higher resolutions and increasingly CPU-bound at lower resolutions, with the measured FPS numbers revealing a clear hierarchy across presets. This analysis walks through the resolution scaling, the distinct roles of the GPU and CPU, and the practical settings choices indicated by the measured rows.

Resolution Scaling

The measured FPS data shows a dramatic drop as resolution increases from 1920x1080 to 3840x2160, but the pattern varies heavily by quality preset. At Low settings, the RTX 4080 SUPER delivers 355.3 FPS at 1080p, falling to 297.5 FPS at 1440p, and then to 156.4 FPS at 4K. That is a 55.9% reduction from 1080p to 4K at Low, indicating that even at the lowest graphics quality, the pixel throughput demands of 4K begin to strain the GPU. However, the 1080p-to-1440p drop at Low is only 16.3%, suggesting that at these lower resolutions, something else — likely the CPU — is capping the frame rate before the GPU becomes fully saturated.

At Ultra settings, the scaling is more linear and more punishing. The system produces 220.1 FPS at 1080p, 138.1 FPS at 1440p, and 72.4 FPS at 4K. The 4K figure is less than one-third of the 1080p figure, which is a classic sign of pure GPU-bound rendering with no CPU limitation. The 1440p-to-4K drop at Ultra is 47.6%, while the 1080p-to-1440p drop is 37.3%. This consistent degradation in performance with each resolution step confirms that the RTX 4080 SUPER's compute resources are the limiting factor at higher settings.

The Medium and High presets sit between these extremes. At Medium, 1080p yields 312.2 FPS, 1440p yields 208.2 FPS, and 4K yields 106.4 FPS. At High, the numbers are 233.5 FPS, 147.4 FPS, and 79.4 FPS respectively. The gap between High and Ultra at 4K is just 7 FPS (79.4 vs. 72.4), which is a small cost for the extra quality. Conversely, the gap between Low and Medium at 1080p is 43.1 FPS (355.3 vs. 312.2), suggesting that Low is already hitting a hard ceiling that Medium barely improves upon. The data overall indicates that at 1080p and 1440p, the CPU and memory subsystem are keeping the GPU well-fed, but at 4K, the GPU's fill rate and shading power become the sole determinant of performance.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the dominant component in this pairing, and its specifications explain why 4K performance falls off so steeply. With 16 GB of GDDR6X memory on a 256-bit bus, the card offers 736.3 GB/s of memory bandwidth — a figure that is likely ample for a simulation game with modest texture requirements. The GPU's boost clock of 2550 MHz and its 10240 shading units provide a theoretical FP32 throughput of 52.22 TFLOPS, which is more than enough for Pc Building Simulator's simple 3D scenes. The card's benchmark results support this: it scores 34245 in PassMark G3D and 246994 in Geekbench OpenCL, placing it in the 88th percentile of all GPUs.

What the data reveals is that the RTX 4080 SUPER is overkill for this game at 1080p and 1440p. At 1080p Low, the 355.3 FPS result is likely limited by the game engine's frame pacing or the CPU's single-thread speed, not by the GPU. At 4K Ultra, however, the GPU's 72.4 FPS result shows a component working hard, and the 4K Low result of 156.4 FPS suggests that even with minimal shading, the pixel fill rate becomes a bottleneck. The card's nearest rival, the AMD Radeon RX 6900 XT, has an average benchmark score of 53489 versus the RTX 4080 SUPER's 53610, a delta of just 0.2%. This near-parity in synthetic tests does not translate to identical gaming performance, but it does indicate that the RTX 4080 SUPER is not uniquely positioned for this workload — any high-end GPU of this class would likely show similar scaling behavior.

FAQ

Q: Why does the FPS drop so much from 1440p to 4K at Low settings?

A: At 1080p and 1440p Low, the system produces 355.3 and 297.5 FPS respectively, which are likely CPU-limited. At 4K Low, the frame rate falls to 156.4 FPS, a 47.4% drop from 1440p, showing that the GPU's pixel throughput becomes the limiting factor once the resolution increases past the CPU's ceiling.

Q: Is the RTX 4080 SUPER a good match for this CPU in this game?

A: At 4K, yes — the GPU is clearly the bottleneck, with 4K Ultra at 72.4 FPS and 4K High at 79.4 FPS. At 1080p, the CPU appears to limit performance, as evidenced by the small gap between Low (355.3 FPS) and Medium (312.2 FPS) compared to the larger gap between Medium and High (233.5 FPS).

Q: What is the best resolution to run this game at?

A: The data shows that 1440p High (147.4 FPS) and 1440p Medium (208.2 FPS) both provide smooth frame rates well above 144 Hz, while 1440p Ultra (138.1 FPS) remains playable. 4K is also viable, with 4K Medium at 106.4 FPS being the highest preset that stays above 100 FPS.

Q: How does the CPU compare to its nearest rivals in synthetic benchmarks?

A: The Ryzen 7 5800XT has an average benchmark score of 29774, which is 0.1% higher than the AMD Ryzen 7 PRO 5755GE (29740) and 0.3% higher than the AMD Ryzen AI 7 PRO 360 (29682). It is 0.3% lower than the AMD Ryzen 7 6800HS (29856).

Q: Does the GPU's 16 GB VRAM matter for this game?

A: The 16 GB GDDR6X memory is likely far more than Pc Building Simulator requires, given its simulation genre and simple textures. The 736.3 GB/s bandwidth is also excessive, which is why the GPU's performance at 4K is more tied to its shading units and fill rate than memory capacity.

Q: What does the combo's rank in the game's benchmark database indicate?

A: The combination ranks 129th out of 1769 tested combos in Pc Building Simulator, placing it in the top 7.3% of all configurations. This suggests that while the system is strong, there are many faster combos for this game, likely those with even newer GPUs.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all presets. Low settings produce 355.3 FPS, Medium produces 312.2 FPS, High produces 233.5 FPS, and Ultra produces 220.1 FPS. The gap between Low and Medium is 43.1 FPS, but the gap between High and Ultra is only 13.4 FPS, indicating that the Ultra preset adds quality without a massive performance penalty at this resolution.

Moving to 2560x1440, the numbers drop but remain high. Low yields 297.5 FPS, Medium yields 208.2 FPS, High yields 147.4 FPS, and Ultra yields 138.1 FPS. The 1440p results show a wider spread between presets than at 1080p, with Low outperforming Ultra by 159.4 FPS. This is the resolution where the GPU's scaling begins to show, as the 4K results are not yet limiting the frame rate.

At 3840x2160, the frame rates fall into a more modest range. Low produces 156.4 FPS, Medium produces 106.4 FPS, High produces 79.4 FPS, and Ultra produces 72.4 FPS. The 4K Low result is still above 144 Hz, which is impressive, but the Ultra result of 72.4 FPS is the only measured row below 100 FPS. The difference between High and Ultra at 4K is just 7 FPS, making Ultra a reasonable choice for users with G-Sync displays.

Across all resolutions, the measured FPS numbers show a consistent pattern: Low and Medium presets are always at least 1.9x faster than Ultra at the same resolution. At 1080p, Low is 1.6x faster than Ultra; at 1440p, Low is 2.2x faster; at 4K, Low is 2.2x faster. This suggests that the Ultra preset introduces effects that are disproportionately expensive on this GPU.

CPU Role

The AMD Ryzen 7 5800XT is a 8-core, 16-thread Zen 3 processor with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. Its 32 MB of L3 cache and 7 nm process node are typical of the Vermeer architecture. In synthetic benchmarks, the CPU achieves a Cinebench R23 multi-core score of 23794 and a single-core score of 3359, with a PassMark multithread score of 27988 and a single-thread score of 3538. These results place it in the 86th percentile of all CPUs.

In Pc Building Simulator, the CPU's role is most evident at 1080p, where the frame rates exceed 300 FPS at Low and Medium settings. The fact that Low (355.3 FPS) and Medium (312.2 FPS) at 1080p are so close suggests that the CPU is saturating the game's main thread, preventing the GPU from fully stretching its legs. At 1440p Low, the 297.5 FPS result is still high, but the 4K Low result of 156.4 FPS shows that the GPU is now the limiting factor.

The CPU's benchmark rivals are all within 0.3% of its average score, including the AMD Ryzen 7 7840H (29868, -0.3%) and the AMD Ryzen 7 PRO 5755GE (29740, +0.1%). This means that swapping the 5800XT for any of these processors would likely produce nearly identical frame rates in this game, as the bottleneck at 1080p is more about single-threaded game logic than raw multi-core performance. The 5800XT's 16 threads provide ample headroom for background processes, but Pc Building Simulator appears to rely on a few heavily loaded threads, which is why its single-core score of 3359 in Cinebench R23 is more relevant than its multi-core score.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target refresh rate. For 4K displays, the Medium preset at 106.4 FPS is the best balance, as it stays above 100 FPS while offering better visuals than Low (156.4 FPS). The High preset at 79.4 FPS is also viable for 60 Hz displays, but the Ultra preset at 72.4 FPS provides only a 7 FPS gain over High, making it a poor trade for the extra quality.

For 1440p, the Medium preset at 208.2 FPS is the strongest recommendation, as it exceeds 200 FPS and leaves room for high-refresh-rate monitors. The High preset at 147.4 FPS is sufficient for 144 Hz displays, while the Ultra preset at 138.1 FPS is marginally below the 144 Hz threshold but still playable. For competitive play or maximum frame rates, the Low preset at 297.5 FPS is the clear choice, though the visual downgrade is significant.

For 1080p, the data shows that the High preset at 233.5 FPS is the sweet spot, offering a 13.4 FPS improvement over Ultra (220.1 FPS) while providing better visuals than Medium (312.2 FPS). The Low preset at 355.3 FPS is unnecessary for most users, as even Ultra exceeds 220 FPS, which is beyond the refresh rate of virtually all monitors. The Medium preset at 312.2 FPS is a solid alternative for those who want smoother motion, but the difference between High and Ultra at this resolution is small enough that choosing Ultra for maximum quality incurs no real penalty.

In all cases, the measured data indicates that this system can run Pc Building Simulator at high frame rates with any preset, and the only scenario where the GPU struggles is 4K Ultra, which still delivers a playable 72.4 FPS. The recommendation is to prioritize Medium or High presets at 4K, Medium at 1440p for maximum smoothness, and High or Ultra at 1080p for the best visual experience.
