# Pc Building Simulator with AMD Ryzen 7 7800X3D + NVIDIA GeForce RTX 4090

Pc Building Simulator, a simulation title released in early 2019, presents an unusual workload for high-end hardware. The measured data for this AMD Ryzen 7 7800X3D and NVIDIA GeForce RTX 4090 combination reveals a game that is far more demanding on the graphics card than the processor, yet the scaling patterns suggest a nuanced relationship between resolution, settings, and the underlying components. This analysis examines the measured FPS across three resolutions and four quality presets, interpreting what the numbers indicate about system balance, GPU limitations, and optimal configuration for this specific pairing.

Resolution Scaling

The FPS drops from 1080p to 4K are substantial, but the magnitude varies significantly depending on the quality preset. At Low settings, the average FPS falls from 378 at 1920x1080 to 172.8 at 3840x2160 — a reduction of 54.3%. This steep decline indicates that even at Low settings, the RTX 4090 is being pushed hard by the pixel count increase, with the GPU becoming the primary bottleneck as resolution climbs. At Medium settings, the drop is from 335.6 to 120.5, a 64.1% decrease, showing that the combination of higher settings and more pixels amplifies the GPU workload considerably.

The High preset tells a similar story: 260.4 FPS at 1080p falls to 83.3 at 4K, a 68% reduction. Ultra settings produce the most dramatic scaling, with 251 FPS at 1080p dropping to 82 at 4K — a 67.3% decline. The fact that Ultra and High at 4K yield nearly identical results (82 vs 83.3 FPS) suggests that at this resolution, the GPU is so saturated that the additional visual fidelity of Ultra over High comes at almost no extra measurable cost in this title. This clustering of results at 4K Ultra and High points to a hard ceiling imposed by the graphics card's rendering capacity rather than the CPU.

Interestingly, the gap between 1080p and 1440p is smaller than the gap between 1440p and 4K at every setting. For example, at Low settings, 1080p delivers 378 FPS, 1440p delivers 327.7 (a 13.3% drop), but 4K drops to 172.8 (a 47.3% drop from 1440p). This non-linear scaling indicates that the game's rendering pipeline becomes exponentially more expensive as pixel count grows, likely due to fill-rate and memory bandwidth demands that scale with resolution. The data implies that at 1080p and 1440p, the CPU has more headroom to feed the GPU, while at 4K, the GPU's raw throughput becomes the sole limiting factor.

GPU Role

The RTX 4090's specifications are central to interpreting these results. With 24 GB of GDDR6X memory on a 384-bit bus, delivering 1.01 TB/s of bandwidth, the card has ample memory resources for a simulation game that likely stores many assets. The 82.58 TFLOPS of FP32 performance and a boost clock of 2520 MHz indicate a GPU that should excel at high-resolution rendering. The measured data confirms this: even at 4K Ultra, the combo maintains 82 FPS, which is playable for a simulation genre where frame rates below 60 are often acceptable.

The GPU's percentile ranking of 91 among all GPUs, with an average benchmark score of 66473, places it near the top of the hierarchy. Its nearest rivals include the NVIDIA Tesla T4 (delta -0.4%) and AMD Radeon Pro Vega 56 (delta -0.9%), though these are professional cards with different driver optimizations. The 128 RT cores and 512 tensor cores suggest the card is prepared for ray-traced workloads, though the game's age (2019) likely does not leverage these features heavily. The memory clock of 1313 MHz (21 Gbps effective) combined with the 384-bit bus provides the bandwidth necessary to avoid stuttering at 4K, which the smooth scaling from High to Ultra (83.3 to 82 FPS) supports.

The data indicates that the GPU is the dominant component in this pairing. At 1080p Low, the 378 FPS result suggests the CPU might be limiting, but the RTX 4090's sheer speed means it can still push enormous frame rates. The 91st percentile ranking and passmark G3D score of 38194 confirm that this is one of the fastest consumer GPUs available, making it the logical bottleneck in a simulation game that does not heavily utilize multi-threaded CPU workloads.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution and desired frame rate. At 1920x1080, all presets deliver well above 250 FPS, with Low at 378, Medium at 335.6, High at 260.4, and Ultra at 251. For competitive or high-refresh-rate gaming, the Low or Medium presets offer the highest headroom, but the difference between High and Ultra is minimal (260.4 vs 251), suggesting that Ultra provides the best visual experience with only a 3.6% performance penalty over High.

At 2560x1440, the story shifts slightly. Ultra delivers 156.6 FPS, High 163.2, Medium 234.6, and Low 327.7. The gap between Ultra and High narrows to just 4.2%, making Ultra a clear choice for visual fidelity without sacrificing smoothness. The 4K resolution presents a more critical decision: Ultra and High are nearly identical (82 vs 83.3 FPS), while Medium jumps to 120.5 and Low to 172.8. For a simulation game where immersion matters, High at 4K offers the best balance — it is visually indistinguishable from Ultra in the measured data, but it provides a slight FPS buffer. Medium at 4K, at 120.5 FPS, is the recommendation for players who prioritize frame rate smoothness over maximum detail, as it delivers a 45% improvement over High while still looking respectable.

The data suggests that the "High" preset is the sweet spot across all resolutions, as it consistently sits near the top of the performance curve without the diminishing returns seen in Ultra. At 1080p, High offers 260.4 FPS versus Ultra's 251 — a negligible difference. At 1440p, High delivers 163.2 versus Ultra's 156.6. At 4K, High at 83.3 beats Ultra's 82. The measured rows indicate no scenario where Ultra provides a meaningful FPS advantage, making High the most efficient choice for this combo.

FAQ

Q: Is this combo overkill for Pc Building Simulator at 1080p?

A: The data shows 378 FPS at 1080p Low and 251 FPS at 1080p Ultra. These figures far exceed typical display refresh rates, indicating the hardware is heavily underutilized at this resolution. The CPU and GPU are both capable of far more than the game demands.

Q: Why do High and Ultra settings produce nearly identical FPS at 4K?

A: At 3840x2160, High averages 83.3 FPS and Ultra averages 82 FPS — a 1.6% difference. This suggests the GPU is saturated at this resolution, and the extra visual features in Ultra do not add measurable rendering cost. The bottleneck is the pixel throughput, not the settings complexity.

Q: Does the 24 GB VRAM on the RTX 4090 impact these results?

A: The 24 GB GDDR6X memory with 1.01 TB/s bandwidth provides ample capacity for this game. The measured FPS does not show any stutter or frame drops that would indicate memory pressure, even at 4K Ultra. The memory subsystem is not a limiting factor in any of the measured rows.

Q: How does this combo rank compared to other tested configurations?

A: The combo ranks 40th out of 1769 tested combinations in Pc Building Simulator, placing it in the top 2.3% of all tested systems. This is consistent with the high percentile rankings of both the CPU (87) and GPU (91).

Q: What is the best settings preset for a 144Hz monitor at 1440p?

A: At 2560x1440, all presets exceed 144 FPS, with Ultra at 156.6 FPS being the lowest measured. Therefore, Ultra is the recommended preset for a 144Hz display, as it provides the highest visual quality while still staying above the refresh rate threshold.

Q: Is the CPU or GPU more important for this game's performance?

A: The scaling patterns indicate the GPU is the primary driver of performance. At 4K, FPS drops significantly from 1080p regardless of settings, which points to GPU-bound rendering. The CPU, with its 8 cores and 16 threads, does not appear to bottleneck even at high frame rates.

How This Combo Ranks

The AMD Ryzen 7 7800X3D and NVIDIA GeForce RTX 4090 combination ranks 40th out of 1769 tested combos in Pc Building Simulator, placing it in the 97.7th percentile of all systems tested. This top-tier ranking is consistent with the individual component performance: the CPU sits in the 87th percentile among all CPUs with an average benchmark score of 31580, while the GPU ranks in the 91st percentile with an average score of 66473. The CPU's nearest rivals include the Intel Core i7-12700F (delta 0.1%), AMD Ryzen 9 5980HX (delta 0.3%), and AMD Ryzen 7 8700G (delta 0.6%), indicating that the 7800X3D is tightly clustered with other high-end processors.

The GPU's nearest rivals are more disparate: the NVIDIA Tesla T4 (delta -0.4%), AMD Radeon Pro Vega 56 (delta -0.9%), and NVIDIA Quadro P6000 (delta -1.3%). These professional cards have similar average benchmark scores but are not designed for gaming, making the RTX 4090's gaming performance notably stronger. The rank of 40 out of 1769 suggests that while there are 39 combinations that outperform this pairing in Pc Building Simulator, they likely consist of even more exotic hardware or configurations better tuned for this specific simulation workload. The data confirms that this combo sits at the upper echelon of tested systems, with only a small fraction of alternatives delivering higher measured FPS.

CPU Role

The AMD Ryzen 7 7800X3D brings 8 cores and 16 threads, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. Its 96 MB of shared L3 cache is a defining feature, likely beneficial for simulation games that may have larger data sets. The CPU's benchmark scores are impressive: Cinebench R23 multicore reaches 29149 and single-core 4115, while Geekbench multicore hits 15101. The 3DMark 16-thread score of 7980 and max-thread score of 7967 indicate strong multi-threaded performance, though the single-thread score of 959 in 3DMark suggests that per-core performance is not the absolute highest.

In Pc Building Simulator, the CPU's role appears secondary to the GPU. The measured FPS at 1080p Low (378) is likely near the CPU's limit for this game, given that the RTX 4090 could theoretically render even higher frame rates. The fact that 1080p Low and Medium (335.6) differ by 11.2% suggests some CPU involvement, but the dramatic drops at 4K (e.g., Low from 378 to 172.8) indicate GPU saturation. The CPU's 120 W TDP and 5 nm process from TSMC, with 11,270 million transistors on a 71 mm² die, make it a power-efficient choice that does not thermally throttle in most scenarios.

The 7800X3D's percentile ranking of 87 and average benchmark score of 31580 place it slightly above its nearest rival, the Intel Core i7-12700F, by 0.1%. This marginal difference suggests that in this game, the CPU choice matters less than the GPU, as the simulation workload likely does not fully utilize the CPU's 3D V-Cache advantage. The dual-channel DDR5 memory support with 83.2 GB/s bandwidth provides sufficient memory throughput, though the game's 2019 release date may not leverage modern memory architectures fully.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values are: Low 378, Medium 335.6, High 260.4, and Ultra 251. The progression from Low to Ultra shows a 33.6% reduction in performance, with the largest drop occurring between Medium and High (75.2 FPS difference). At 2560x1440, the values are: Low 327.7, Medium 234.6, High 163.2, and Ultra 156.6. The drop from Low to Ultra is 52.2%, indicating that higher resolution amplifies the settings impact. At 3840x2160, the numbers are: Low 172.8, Medium 120.5, High 83.3, and Ultra 82. The difference between Low and Ultra is 52.5%, but the gap between High and Ultra is just 1.3 FPS.
