Pc Building Simulator

Pc Building Simulator, a simulation title from 2019, presents an unusual workload where the CPU is tasked with managing complex system-building logic while the GPU renders the workshop environment. The AMD Ryzen 7 5800XT and NVIDIA GeForce RTX 4080 combination produces frame rates that are exceptionally high across all settings, but the scaling patterns reveal a workload that is heavily reliant on the processor’s single-thread performance rather than the graphics card’s raw throughput. This analysis walks through the measured FPS data, ranking position, and component roles to interpret how this specific pairing behaves in this game.

Resolution Scaling

The measured FPS data shows a clear and consistent pattern: performance drops significantly as resolution increases, but the rate of that drop is far shallower than what would be expected from a GPU-bound scenario. At 1080p with Low settings, the combo achieves 356 FPS. Moving to 1440p Low reduces that to 297 FPS, a decline of roughly 16.6%. At 4K Low, the average drops further to 155 FPS, which is a 47.8% reduction from the 1440p figure. This scaling is unusual because a pure GPU bottleneck would typically show a much steeper decline from 1440p to 4K, often exceeding 50% due to the quadrupling of pixel count.

The pattern becomes more telling when examining the High preset. At 1080p High, the system produces 235 FPS. At 1440p High, it falls to 148 FPS, a 37% drop. At 4K High, it reaches 78 FPS, which is a 47.3% reduction from 1440p. The fact that the 1080p-to-1440p drop (37%) is nearly as large as the 1440p-to-4K drop (47%) suggests that the CPU is the primary limiter at lower resolutions, while the GPU begins to take over as resolution climbs. If the GPU were the sole bottleneck, the 1080p-to-1440p gap would be smaller than the 1440p-to-4K gap.

Looking at the Medium preset, which has min/max data, the trend continues. At 1080p Medium, the average is 313 FPS with a minimum of 266 FPS. At 1440p Medium, the average drops to 210 FPS (a 32.9% decrease), and at 4K Medium, it falls to 110 FPS (a 47.6% decrease from 1440p). The minimum FPS values also scale proportionally: 266 at 1080p, 179 at 1440p, and 93 at 4K. This consistent proportional decline across all settings indicates that the game’s engine is not purely GPU-bound, even at 4K, where the RTX 4080’s 16 GB of VRAM and 716.8 GB/s bandwidth should be ample.

The Ultra preset shows the smallest absolute numbers but the same relative pattern: 224 FPS at 1080p, 141 FPS at 1440p (a 37.1% drop), and 74 FPS at 4K (a 47.5% drop from 1440p). The near-identical percentage drops across High, Medium, and Ultra suggest that the rendering pipeline has a fixed CPU overhead that scales with resolution only through the increased pixel fill rate demand. At 1080p, the CPU is clearly the limiting factor, as evidenced by the 356 FPS ceiling on Low settings. At 4K, the GPU starts to matter more, but the fact that even 4K Ultra maintains 74 FPS indicates that the RTX 4080 is never fully saturated.

How This Combo Ranks

In the database of tested combinations, this pairing of the AMD Ryzen 7 5800XT with the NVIDIA GeForce RTX 4080 ranks 293rd out of 3,723 total combos for Pc Building Simulator. This places it in the top 7.9% of all tested configurations, which is a strong showing but not at the very top. The percentile data for the individual components supports this: the CPU sits at the 81st percentile among all processors, and the GPU sits at the 86th percentile among all graphics cards. The combo rank being lower than either component’s individual percentile suggests that the game does not fully utilize the strengths of both parts simultaneously.

The rank of 293 out of 3,723 means there are 292 other combinations that achieve higher average FPS in this specific game. Given the game’s simulation nature, it is likely that many of those higher-ranked combos feature CPUs with superior single-thread performance, as Pc Building Simulator appears to be heavily CPU-bound at lower resolutions. The RTX 4080’s nearest rivals in the GPU benchmark database include the RTX 4080 SUPER, which scores 0.1% higher on average, and the AMD Radeon Pro W5700X, which scores 1.1% lower. These tiny deltas indicate that the GPU tier is not the deciding factor for ranking here; instead, the CPU’s ability to feed the renderer is what separates the top 8% from the rest.

The CPU’s nearest rivals in the benchmark database are instructive. The AMD Ryzen 7 7840H scores within 0% of the 5800XT, and the Ryzen 7 8845HS scores 0.3% lower. These are mobile processors with similar multi-threaded capabilities, yet they might perform differently in Pc Building Simulator due to variations in single-thread behavior. The fact that the 5800XT’s average benchmark score is 29,879, while the RTX 4080’s is 54,247, shows that the GPU has far more raw compute headroom, yet the game’s frame rates are not proportional to that gap. This reinforces the conclusion that the combo’s rank is largely determined by CPU performance, not GPU prowess.

CPU Role

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Vermeer. It has a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with a 32 MB shared L3 cache. In synthetic benchmarks, its single-thread score in Cinebench R23 is 3,359, while its multi-core score is 23,794. The 3DMark 2-thread score is 1,879, which scales up to 7,683 for 16 threads, showing excellent multi-threading efficiency. However, Pc Building Simulator’s performance pattern suggests that the game relies heavily on one or two threads, as the frame rates at 1080p Low (356 FPS) are far higher than what a fully GPU-bound title would produce, yet they still cap out at a level that indicates CPU instruction issue limits.

The game’s simulation logic, which involves tracking component compatibility, power draw calculations, and system boot sequences, is inherently serial. The 5800XT’s single-thread performance, as measured by the 3DMark single-thread score of 959 and PassMark single-thread score of 3,535, is strong but not class-leading. The CPU’s boost clock of 4.80 GHz helps, but the data shows that at 1080p, the frame rate ceiling is around 356 FPS on Low settings. This suggests that the game’s main thread is the bottleneck, and additional GPU power would not push this number higher.

The 8-core, 16-thread configuration is likely overkill for this title, as the game probably does not scale well beyond a few threads. The multi-core benchmarks, such as Cinebench R23’s 23,794 points, are impressive, but they do not translate directly to Pc Building Simulator’s frame rates. The fact that the combo ranks 293rd, despite having a CPU that beats the vast majority of processors in synthetic tests, indicates that the game favors higher single-thread performance over raw core counts. The Ryzen 7 5800XT’s nearest CPU rivals, including the Ryzen 5 9600X which scores 0.6% higher on average, might offer marginally better single-thread performance, which could explain why some combos rank higher.

FAQ

Q: What is the best resolution to play at with this combo for the highest frame rate?

A: The data shows 1920x1080 provides the highest average FPS across all settings, with the Low preset reaching 356 FPS. At 2560x1440, the maximum average is 297 FPS on Low, and at 3840x2160, the maximum average is 155 FPS on Low.

Q: Does the RTX 4080’s 16 GB VRAM matter for this game?

A: The measured FPS data shows no indication of VRAM limitations, as even at 4K Ultra with 74 FPS, there are no reported minimum FPS drops that would suggest memory pressure. The game is not graphically demanding enough to stress the 16 GB GDDR6X buffer.

Q: Is the Ryzen 7 5800XT the bottleneck at 1080p?

A: Yes, the evidence is strong. At 1080p Low, the system achieves 356 FPS, but this number does not increase proportionally with GPU headroom. The CPU’s single-thread performance, as measured by a 3DMark single-thread score of 959, appears to cap the frame rate.

Q: How does this combo compare to the highest-ranked ones?

A: This combo ranks 293rd out of 3,723 tested combinations, placing it in the top 8%. The individual components rank at the 81st percentile (CPU) and 86th percentile (GPU), but the game’s CPU-bound nature means that combos with faster single-threaded CPUs likely rank higher.

Q: What is the frame rate difference between Low and Ultra at 4K?

A: At 3840x2160, the Low preset averages 155 FPS, while the Ultra preset averages 74 FPS. This is a 52.3% reduction in frame rate when moving from the lowest to the highest quality settings.

Q: Does the game benefit from the CPU’s 16 threads?

A: The benchmark data does not show a clear scaling benefit from multi-threading. The 16-thread 3DMark score is 7,683, but the frame rates in Pc Building Simulator are more closely tied to the single-thread score of 959, suggesting the game primarily uses one or two threads.

GPU Role

The NVIDIA GeForce RTX 4080 is a high-end graphics card based on the Ada Lovelace architecture, with 9,728 shading units, 76 RT cores, and a boost clock of 2505 MHz. It has 16 GB of GDDR6X memory on a 256-bit bus, providing 716.8 GB/s of bandwidth. In synthetic benchmarks, it achieves a PassMark G3D score of 34,457 and a 3DMark Steel Nomad DX12 score of 6,567. Despite this massive compute capability, Pc Building Simulator does not come close to saturating the GPU. At 1080p Low, the frame rate is 356 FPS, but the GPU is likely idle waiting for CPU instructions.

The GPU’s role becomes more apparent as resolution increases. At 4K Ultra, the average FPS drops to 74, which is still far above playable thresholds but represents a 79.2% reduction from the 1080p Low figure. The pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are more than sufficient for this title, as the game’s visual complexity is low compared to modern shooters or open-world titles. The RTX 4080’s nearest GPU rivals, including the RTX 4080 SUPER with a 0.1% higher average score, would perform nearly identically in this game, confirming that the GPU is not the limiting factor.

The VRAM usage is a non-issue. The game’s 4K Ultra preset, which is the most demanding, still only requires a fraction of the 16 GB available. The GPU’s memory bandwidth of 716.8 GB/s is also overkill, as the frame rates scale with resolution in a way that suggests the rendering pipeline is not bandwidth-limited. The RTX 4080’s FP32 performance of 48.74 TFLOPS is impressive, but Pc Building Simulator’s workload does not leverage this raw compute power. Instead, the GPU is effectively coasting, with its performance only becoming relevant at 4K where the pixel fill rate starts to matter.

Settings Recommendations

Based on the measured FPS data, the ideal settings depend on the target resolution and desired smoothness. At 1920x1080, all settings produce excellent frame rates, but the Medium preset offers a balanced experience with 313 FPS average and a minimum of 266 FPS. The Ultra preset at 1080p drops to 224 FPS, which is still very smooth but does not provide a meaningful visual improvement for a simulation game. For players with high refresh rate monitors, the High preset at 235 FPS is a strong choice, as it provides a 3.6% frame rate increase over Ultra while likely offering nearly identical visual fidelity in this type of game.

At 2560x1440, the Medium preset delivers 210 FPS with a minimum of 179 FPS, which is ideal for smooth gameplay. The High preset at 148 FPS is also acceptable, but the jump from Medium to High costs a 29.5% performance hit. The Ultra preset at 141 FPS is only 4.7% slower than High, suggesting that the visual differences between High and Ultra are not worth the performance trade-off. At this resolution, the Low preset provides 297 FPS, but it is unnecessary given the medium preset’s headroom.

At 3840x2160, the situation changes. The High preset averages 78 FPS, which is just above the 60 FPS threshold for smoothness, but the Medium preset at 110 FPS is a safer choice for maintaining fluidity. The Low preset at 155 FPS is the best option for maximum performance, but it sacrifices visual quality. The Ultra preset at 74 FPS is playable but leaves no margin for frame rate dips in complex scenes. Given the game’s simulation nature, where system-building menus and part browsing are common, the Medium preset at 4K provides the best balance of visual clarity and performance. For competitive or fast-paced interaction, the Low preset at 1440p or 1080p is recommended.

Measured FPS Breakdown

The complete set of measured frame rates is as follows. At 1920x1080, the Low preset averages 356 FPS, the Medium preset averages 313 FPS with a minimum of 266 FPS and a maximum of 360 FPS, the High preset averages 235 FPS, and the Ultra preset averages 224 FPS. At 2560x1440, the Low preset averages 297 FPS, the Medium preset averages 210 FPS with a minimum of 179 FPS and a maximum of 242 FPS, the High preset averages 148 FPS, and the Ultra preset averages 141 FPS. At 3840x2160, the Low preset averages 155 FPS, the Medium preset averages 110 FPS with a minimum of 93 FPS and a maximum of 126 FPS, the High preset averages 78 FPS, and the Ultra preset averages 74 FPS.

The data shows a consistent hierarchy: at every resolution, the Low preset is fastest, followed by Medium, High, and Ultra. The gap between Low and Medium is large, averaging about 31% across all resolutions. The gap between Medium and High is also significant, averaging about 39%, while the gap between High and Ultra is small, averaging about 4%. This suggests that the Ultra preset offers diminishing returns over High, and the Medium preset is a sweet spot for performance per quality step. The minimum FPS values for the Medium preset show that the 1% lows scale proportionally with resolution, from 266 FPS at 1080p to 93 FPS at 4K, indicating no sudden stutters or memory-related hitches.
