Pc Building Simulator

Resolution Scaling

The measured FPS data for Pc Building Simulator with the AMD Ryzen 9 9950X3D and NVIDIA GeForce RTX 4080 reveals a dramatic scaling pattern that clearly identifies the GPU as the primary bottleneck at higher resolutions. Moving from 1920x1080 to 2560x1440 at Ultra settings, the average frame rate drops from 224 FPS to 141 FPS — a 37% reduction. The subsequent step to 3840x2160 at Ultra yields 74 FPS, another 47.5% decline. This steep, nearly linear scaling with pixel count is the signature of a GPU-limited scenario.

At Low settings, the scaling is even more pronounced. The 1080p Low average of 470 FPS falls to 297 FPS at 1440p (a 36.8% drop) and then to 155 FPS at 4K (a 47.8% drop from 1440p). The fact that the 4K Low result (155 FPS) is still lower than the 1080p Ultra result (224 FPS) underscores how resolution dominates the performance envelope regardless of visual complexity.

The data indicates that at 1080p, the combination is heavily CPU-bound in this simulation title. The jump from 224 FPS at Ultra to 470 FPS at Low (a 109.8% increase) shows that the GPU has enormous headroom when pixel count is low. The Ryzen 9 9950X3D's 16 cores and 32 threads, with a boost clock of 5.70 GHz, are clearly capable of feeding the RTX 4080 at these frame rates. However, the 4K results tell a different story — the gap between Low (155 FPS) and Ultra (74 FPS) narrows to 109.5% improvement, still large but compressed by the sheer pixel throughput required.

At 4K, the RTX 4080's 16 GB of GDDR6X memory and 716.8 GB/s bandwidth become the limiting factors. The 256-bit bus width and 22.4 Gbps effective memory clock are sufficient for this simulation, but the 48.74 TFLOPS of FP32 compute is what ultimately caps performance. The 4K Medium result of 110 FPS, compared to 4K Low at 155 FPS, shows a 40.9% penalty for moving up one preset tier.

Settings Recommendations

The benchmark results point to Medium settings as the optimal balance for this hardware combination, particularly at higher resolutions. At 3840x2160, Medium delivers 110 FPS average with a minimum of 93 FPS and maximum of 126 FPS. This is the only 4K preset that maintains a comfortable margin above 90 FPS throughout the measured range, making it the clear choice for smooth gameplay without visual compromise.

High settings at 4K produce 78 FPS average, which dips below the 80 FPS threshold that many players consider the floor for responsive simulation gameplay. The step from Medium to High costs 32 FPS (29.1% reduction), while the step from High to Ultra costs only 4 FPS (5.1% reduction). This inverted scaling — where the highest preset tier costs less than the middle tier — suggests that Ultra at 4K is nearly a free upgrade over High, but neither reaches the 90 FPS minimum that Medium achieves.

At 2560x1440, Medium delivers 210 FPS average with a minimum of 179 FPS and maximum of 242 FPS. This is far beyond what any display can refresh, so the recommendation shifts to visual quality. Ultra at 1440p produces 141 FPS, which remains above 140 FPS and is still exceptionally smooth. For players with 144 Hz or 165 Hz monitors, 1440p Ultra is the superior choice, sacrificing 69 FPS (32.9%) versus Medium but gaining the full visual fidelity.

At 1920x1080, all presets deliver playable results, but the data shows diminishing returns. Low produces 470 FPS, Medium 333 FPS, High 235 FPS, and Ultra 224 FPS. The jump from High to Ultra costs only 11 FPS (4.7%), making Ultra the obvious choice at 1080p for any player prioritizing image quality over extreme frame rates. The Medium preset at 1080p offers the best risk-adjusted profile with a 283 FPS minimum, ensuring no frame drops below 280 FPS even in heavy simulation scenes.

GPU Role

The NVIDIA GeForce RTX 4080 plays the decisive role in this combination's 4K performance. With 16 GB of GDDR6X memory on a 256-bit bus delivering 716.8 GB/s bandwidth, the card has ample memory capacity for Pc Building Simulator's asset streaming. The 4K Medium result of 110 FPS, with a minimum of 93 FPS, shows that the GPU's 9728 shading units and 112 ROPs are well-matched to this simulation's rendering demands.

The clock behavior is telling. The RTX 4080's base clock of 2205 MHz and boost clock of 2505 MHz represent a 13.6% boost headroom. This boost capability is what allows the card to maintain 155 FPS at 4K Low, a result that would be unattainable at base clocks given the 4K Ultra result of 74 FPS. The 76 RT cores and 304 tensor cores contribute to the card's overall 48.74 TFLOPS FP32 throughput, though Pc Building Simulator's rendering workload appears to favor traditional rasterization.

The GPU's 320 W TDP and triple-slot form factor indicate a high-power design, but the benchmark results show that this power budget is effectively translated into frame rate. The card's position in the benchmark database — 86th percentile among all GPUs with an average benchmark score of 54247 — places it just 0.1% ahead of the RTX 4080 SUPER (54209) and 1.1% behind the Radeon Pro W5700X (54828). This tight grouping explains why the 4K results are so consistent: the RTX 4080 is operating at the edge of its performance class.

At 1080p, the GPU's role recedes. The 470 FPS Low result and 333 FPS Medium result show that the card is far from saturated, with the CPU becoming the limiting factor. The 4K results, however, demonstrate that the RTX 4080's 16 GB memory buffer is sufficient — the 4K Ultra result of 74 FPS is not memory-constrained but compute-constrained, as evidenced by the modest 4 FPS difference between High and Ultra.

How This Combo Ranks

The AMD Ryzen 9 9950X3D + NVIDIA GeForce RTX 4080 combination ranks 171st out of 3723 tested combinations in Pc Building Simulator, placing it in the top 4.6% of all configurations. This ranking reflects the strength of both components, though the data shows that the CPU is the standout performer relative to its peers.

The CPU's percentile ranking of 95 among all processors is exceptional. Its average benchmark score of 75779 places it just 0.1% ahead of the AMD Ryzen 7 PRO 9755 (75738) and AMD Ryzen 7 PRO 9755X3D (75716), and 0.3% ahead of the AMD EPYC 8224P (75582). The nearest rival, Intel Core Ultra 9 285, trails by 0.4% with a score of 75488. This tight clustering at the top of the CPU charts means that the 9950X3D's 171st combo ranking is driven more by the GPU's relative position than by any CPU deficiency.

The GPU's percentile ranking of 86 is notably lower than the CPU's 95, and its average benchmark score of 54247 places it in a competitive but not dominant position. The RTX 4080 SUPER matches it within 0.1% (54209), while the Radeon Pro W5700X leads by 1.1% (54828) and the Radeon RX 6750 GRE 12 GB leads by 2.6% (55698). This 2.7% spread among the nearest rivals (including the Radeon 8060S at 55757) suggests that the GPU is the limiting factor in this combo's ranking.

The 171st rank out of 3723 combinations indicates that many configurations with faster GPUs or more optimized pairings achieve higher scores in Pc Building Simulator. The data suggests that pairing the 9950X3D with a higher-tier GPU would likely improve the ranking, as the CPU has significant headroom at 1080p where it achieves 470 FPS at Low settings.

CPU Role

The AMD Ryzen 9 9950X3D's 16 cores and 32 threads, based on the Zen 5 architecture with Granite Ridge codename, provide exceptional processing power for Pc Building Simulator's simulation logic. The CPU's 128 MB of L3 cache, combined with 80 KB L1 and 1 MB L2 per core, ensures that game state calculations and physics updates have ample fast-access storage. The 89.6 GB/s dual-channel DDR5 memory bandwidth supports the high thread counts without creating a memory bottleneck.

The CPU's performance across synthetic benchmarks confirms its capability. The Cinebench R23 multicore score of 42018 and single-core score of 2259 highlight the balance between multi-threaded throughput and single-thread responsiveness. The 3DMark results show scaling from 2549 at 2 threads to 17184 at max threads, with 16374 at 16 threads — indicating that the CPU scales effectively up to its full core count. The Geekbench multicore score of 26736 and single-core score of 3064 reinforce this dual strength.

The 5.70 GHz boost clock is the critical factor for Pc Building Simulator's single-threaded game logic. The 3DMark single-thread score of 1292 and PassMark single-thread score of 4737 demonstrate that the CPU can deliver high per-core performance, which is essential for simulation games that often have a primary thread handling game state updates. The 4.30 GHz base clock ensures sustained performance under multi-threaded loads without thermal throttling.

The 170 W TDP and 4 nm TSMC process node (with 16,630 million transistors on a 2x 70.6 mm² die) show that the CPU is designed for high sustained performance. The PassMark multithread score of 70255 and physics score of 5670 confirm that the CPU can handle the computational load of Pc Building Simulator's simulation, which benefits from the 32 threads when managing multiple concurrent systems.

In the benchmark data, the CPU's role is most evident at 1080p. The 470 FPS Low result represents a scenario where the GPU is not the bottleneck, and the CPU's ability to feed frames at that rate is a direct result of its high single-thread performance and large cache. The 224 FPS Ultra result at 1080p shows that even with increased graphical load, the CPU maintains sufficient frame pacing.

Measured FPS Breakdown

1920x1080

At 1080p, the measured results show a wide spread across settings. Low delivers 470 FPS average, Medium 333 FPS (with a minimum of 283 and maximum of 383), High 235 FPS, and Ultra 224 FPS. The progression from Low to Medium represents a 29.1% reduction, Medium to High a 29.4% reduction, and High to Ultra a 4.7% reduction. The tight minimum of 283 FPS at Medium indicates that even in the most demanding scenes, the combination maintains high frame rates.

2560x1440

At 1440p, the results scale predictably. Low produces 297 FPS, Medium 210 FPS (minimum 179, maximum 242), High 148 FPS, and Ultra 141 FPS. The Medium result's minimum of 179 FPS is still above most high-refresh displays, while the Ultra result at 141 FPS is exactly at the threshold of 144 Hz monitors. The drop from Low to Medium (29.3%) mirrors the 1080p pattern, but the High to Ultra step at 1440p costs only 7 FPS (4.7%), consistent with the 1080p behavior.

3840x2160

At 4K, the data shows the GPU's limits. Low achieves 155 FPS, Medium 110 FPS (minimum 93, maximum 126), High 78 FPS, and Ultra 74 FPS. The Medium preset is the only one that maintains a minimum above 90 FPS. The step from Medium to High costs 32 FPS (29.1%), while High to Ultra costs 4 FPS (5.1%). The 4K Low result of 155 FPS is 47.8% lower than the 1440p Low result of 297 FPS, demonstrating the quadratic scaling of pixel count.

The complete data set reveals a consistent pattern: the Medium preset at each resolution provides the best minimum frame rate relative to its average, with the minimum averaging 86.4% of the average across all three resolutions. The Ultra preset at each resolution shows the smallest penalty for the highest visual quality, with the High to Ultra delta averaging just 4.9%. This suggests that Pc Building Simulator's Ultra preset is efficiently implemented, offering enhanced visuals without proportional performance cost.
