Pc Building Simulator

Pc Building Simulator is a simulation title that stresses system configuration logic more than raw rendering, but the measured FPS data for the AMD Ryzen 9 5950X and NVIDIA GeForce RTX 4080 SUPER combination reveals distinct performance ceilings at each resolution. The combo achieves a rank of 133 out of 1769 tested configurations, placing it in the top 7.5% of all pairings. This analysis breaks down how the CPU and GPU interact across resolution and quality settings, using only the measured frame rates and hardware specifications provided.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, but the pattern reveals where the bottleneck shifts. At 1080p Low, the combo produces 350.3 FPS, while at 4K Low it falls to 152.1 FPS—a reduction of 56.6%. This scaling is less severe than the 4K-to-1080p ratio for High settings, where the drop from 235 FPS to 76.1 FPS represents a 67.6% decline. The data suggests that at lower quality presets, the CPU (with its 16 cores and 32 threads) can feed frames faster, but the GPU's rendering load at 4K becomes the limiting factor.

At Medium settings, the scaling from 1080p (305.3 FPS) to 4K (110.2 FPS) is a 63.9% reduction, while Ultra settings show a 66.4% drop (223 FPS to 75 FPS). The consistency of these percentages—hovering between 56% and 68%—indicates that resolution scaling is primarily GPU-bound, as the RTX 4080 SUPER's 16 GB of GDDR6X memory and 736.3 GB/s bandwidth must handle exponentially more pixels at 4K. The 1080p-to-1440p transition is milder: High settings drop from 235 FPS to 148.1 FPS (37% reduction), while Low settings fall from 350.3 FPS to 296.2 FPS (15.4% reduction). This smaller delta at Low settings implies that at 1080p Low, the CPU is nearing its frame delivery limit, and the GPU has headroom that gets consumed as resolution increases.

The 4K Ultra result of 75 FPS is notably close to the 4K High result of 76.1 FPS, differing by only 1.1 FPS. This near-identical performance suggests that beyond High settings, the game's Ultra preset adds negligible GPU load for this hardware, possibly due to simulation logic being CPU-bound even at 4K. Conversely, the gap between 4K Low (152.1 FPS) and 4K Medium (110.2 FPS) is 41.9 FPS, showing that quality presets have a more significant impact at lower resolutions where the GPU is less saturated.

GPU Role

The RTX 4080 SUPER's specifications directly explain its performance in this title. With a base clock of 2295 MHz and a boost clock of 2550 MHz, the GPU's compute throughput is substantial, but the game's simulation nature means the 10240 shading units and 80 RT cores are not fully utilized for physics or logic. The 16 GB VRAM is more than sufficient for any preset at any resolution, so memory capacity is not a limiting factor. Instead, the 256-bit memory bus and 736.3 GB/s bandwidth become relevant when moving from 1440p to 4K, where the pixel fill rate demands increase.

The GPU's benchmark scores show it sits at the 88th percentile among all GPUs, with an average benchmark score of 53610. Its nearest rival, the AMD Radeon RX 6900 XT, scores 53489—a delta of just 0.2%—meaning the RTX 4080 SUPER is effectively tied with that card in synthetic tests. However, in this game, the GPU's role is secondary to the CPU at lower resolutions. At 1080p Low, the 350.3 FPS result is likely limited by the CPU's single-thread performance (3dmark_single_thread score of 944) rather than the GPU's raw power. The CPU's boost clock of 4.90 GHz and 64 MB L3 cache help maintain high frame rates, but the GPU's 52.22 TFLOPS FP32 throughput is only fully exercised at 4K.

The GPU's 320 TMUs and 112 ROPs contribute to texture and pixel processing, which explains why the 4K Medium (110.2 FPS) and 4K High (76.1 FPS) results differ by 34.1 FPS—a larger gap than between High and Ultra (1.1 FPS). This suggests that Medium settings offload some simulation work to the CPU, while High and Ultra keep the GPU busier with effects that have diminishing returns. The GPU's 5 nm process node and 45,900 million transistors are architectural advantages, but the game's release date of 2019 means it was not designed to leverage Ada Lovelace features like DLSS 3 frame generation, which would otherwise boost 4K performance.

How This Combo Ranks

The combo rank of 133 out of 1769 tested configurations places this pairing in the 92.5th percentile of all combinations. This is a strong result, but the ranking reflects the entire system's balance rather than just peak FPS. The CPU's percentile vs all CPUs is 93, and the GPU's percentile vs all GPUs is 88, so the combo slightly underperforms what those individual percentiles might suggest—likely because the 5950X's 16-core design is overkill for a game that may not scale beyond 8 threads. The CPU's 3dmark_8_threads score of 6598 versus its 3dmark_max_threads score of 11597 indicates that multithreaded scaling tapers off, and Pc Building Simulator likely benefits more from the single-thread score of 944.

Relative to other combos, this pairing's rank is solid but not elite. The CPU's nearest rivals include the Intel Core i5-14600K (avg score 49166, delta -0.2%) and the Intel Core i5-14600KF (49367, delta -0.6%), both of which have fewer cores but potentially better game-specific performance. The GPU's nearest rivals, the AMD Radeon RX 6900 XT (delta 0.2%) and Radeon Pro W6600M (delta 0.4%), are within striking distance, meaning a different GPU could yield similar or better results without the 5950X's high core count. The combo's rank of 133 out of 1769 suggests that many configurations with mid-range CPUs and high-end GPUs achieve comparable FPS, as the game's CPU demands are modest.

The data indicates that this combo is in the top 10% of tested systems, but the gap between rank 133 and higher ranks is likely driven by CPUs with faster single-thread performance or GPUs with higher clock speeds. The 5950X's 3dmark_single_thread score of 944 is moderate, while the RTX 4080 SUPER's boost clock of 2550 MHz is high, but the GPU's 88th percentile ranking means there are faster options. For a simulation game, the CPU's 16 cores and 32 threads are largely idle, so a more balanced pairing might rank higher.

FAQ

Q: What is the best resolution for this combo to maintain high FPS?

A: At 1080p, the combo delivers 223 FPS on Ultra and 235 FPS on High, both well above typical monitor refresh rates. At 1440p, High settings produce 148.1 FPS, while 4K Ultra drops to 75 FPS, which is still playable but close to the 60 FPS threshold.

Q: How does the CPU affect performance at 1080p Low?

A: The 1080p Low result of 350.3 FPS is the highest measured FPS, but the CPU's 3dmark_single_thread score of 944 and 3dmark_2_threads score of 1856 suggest single-thread limits. The 4.90 GHz boost clock helps, but the game likely cannot fully use the 16 cores, so the CPU becomes the bottleneck at low settings.

Q: Is the RTX 4080 SUPER's 16 GB VRAM sufficient for 4K Ultra?

A: Yes, the 16 GB GDDR6X memory is more than enough for this game, as the 4K Ultra result of 75 FPS shows no VRAM-related stuttering. The 736.3 GB/s bandwidth and 256-bit bus handle the pixel load, but the FPS is still limited by the GPU's rendering throughput.

Q: Why is there only a 1.1 FPS difference between 4K High and 4K Ultra?

A: The 4K High result is 76.1 FPS and 4K Ultra is 75 FPS, nearly identical. This suggests the Ultra preset adds little GPU workload beyond High, possibly because the game's simulation logic becomes CPU-bound at these settings, or the visual effects have diminishing returns.

Q: How does this combo compare to its nearest GPU rival?

A: The RTX 4080 SUPER has an average benchmark score of 53610, while the AMD Radeon RX 6900 XT scores 53489—a 0.2% difference. In this game, the measured FPS would likely be similar, as the GPU is not the primary bottleneck at lower resolutions.

Q: What does the combo rank of 133 out of 1769 mean for gaming?

A: It means this pairing outperforms 92.5% of tested combinations. However, the CPU's 93rd percentile and GPU's 88th percentile rankings suggest the combo is slightly less than the sum of its parts, due to the game's limited multithreading and the CPU's high core count being underutilized.

Measured FPS Breakdown

1080p (1920x1080): The lowest quality preset delivers the highest FPS at 350.3, followed by Medium at 305.3, High at 235, and Ultra at 223. The gap between Low and Medium is 45 FPS, while the gap between High and Ultra is only 12 FPS. This indicates that the game's quality settings scale non-linearly, with Low being significantly lighter on the GPU.

1440p (2560x1440): Low settings produce 296.2 FPS, Medium drops to 207, High is 148.1, and Ultra is 139.9. The difference between Low and Medium is 89.2 FPS, which is the largest single-step drop across any resolution. High to Ultra shows only an 8.2 FPS difference, reinforcing that Ultra has minimal impact over High.

4K (3840x2160): Low settings yield 152.1 FPS, Medium falls to 110.2, and High (76.1) and Ultra (75) are nearly identical. The drop from Low to Medium is 41.9 FPS, while High to Ultra is just 1.1 FPS. At 4K, the GPU's pixel fill rate becomes the bottleneck, as evidenced by the 50% reduction from Low to High (152.1 to 76.1 FPS).

Across all resolutions, the pattern is consistent: Low settings are 20-50% faster than Medium, and High is only slightly faster than Ultra. The 1080p Low result of 350.3 FPS is the absolute maximum measured, indicating that the CPU can push over 350 frames per second when GPU load is minimal. The 4K Ultra result of 75 FPS is the minimum measured, still above playable thresholds. The data confirms that this combo is well-suited for high-refresh-rate 1080p and 1440p gaming, with 4K performance being acceptable but not exceptional.
