Pc Building Simulator

# Pc Building Simulator — AMD Ryzen 7 9800X3D + NVIDIA GeForce RTX 4090

This combination of AMD's Zen 5 flagship and NVIDIA's Ada Lovelace flagship produces an extraordinary spread of frame rates in Pc Building Simulator, ranging from 79.9 FPS at 4K Ultra to 446.7 FPS at 1080p Low. The data reveals a system that is almost never the bottleneck, with the simulation's modest graphical demands allowing the CPU's 3D V-Cache architecture to dominate at lower resolutions while the GPU takes over at 4K. The measured results place this combo 19th out of 1,769 tested configurations, a top-1.1% finish that underscores how close to the ceiling this pairing sits.

Resolution Scaling

The FPS drop from 1080p to 4K tells a clear story about where the workload shifts. At Low settings, the average frame rate falls from 446.7 FPS at 1920x1080 to 172.4 FPS at 3840x2160 — a 61.4% reduction. That steep decline indicates the RTX 4090 becomes the limiting factor as pixel count climbs, since the CPU has already demonstrated it can feed far more frames than the GPU can render at 4K. At Ultra settings, the same resolution change drops performance from 248.6 FPS to 79.9 FPS, a 67.9% cut that reinforces the GPU-bound nature of the highest preset.

The intermediate resolutions show how gracefully this combo scales. At 2560x1440, Low settings produce 327.4 FPS, which is 73.3% of the 1080p Low result. Medium settings at 1440p deliver 230.7 FPS, or 62.7% of the 1080p Medium figure. High settings at 1440p reach 163.5 FPS, which is 63.5% of the 1080p High number. The consistency of these ratios — all clustering between 62% and 73% — suggests a balanced scaling curve where neither component creates a sudden cliff, but the GPU's rendering load grows predictably with pixel count.

What stands out is the 4K Ultra result: 79.9 FPS is still comfortably above 60 FPS, meaning even the heaviest preset at the highest resolution remains playable. The data implies that at 1080p and 1440p, the Ryzen 7 9800X3D's 96 MB of shared L3 cache and 5.20 GHz boost clock keep the CPU from ever becoming a constraint, while the RTX 4090's 24 GB of GDDR6X memory and 1.01 TB/s bandwidth handle the bandwidth demands of higher resolutions without noticeable degradation.

How This Combo Ranks

The comboRankInGame field places this pairing at rank 19 out of 1,769 tested combos, which puts it in the top 1.1% of all configurations. This is a remarkable position for a game that is not typically considered a hardware stress test — Pc Building Simulator is a simulation title, not a AAA shooter, yet the data shows this combo still outperforms 98.9% of tested pairings. The ranking suggests that while the game's rendering demands are modest, the combination of the 9800X3D's single-thread prowess and the RTX 4090's raw throughput creates a ceiling that very few systems can approach.

The CPU's percentileVsAllCpus of 90 and the GPU's percentileVsAllGpus of 91 both indicate top-decile hardware, but the combo's rank 19 out of 1,769 is even more selective. This implies that Pc Building Simulator rewards the specific strengths of this pairing — the CPU's high clock speeds and large cache for simulation logic, and the GPU's massive memory bandwidth for texture streaming. The gap between the combo's rank and the individual components' percentiles suggests that this game particularly appreciates the 9800X3D's 8 cores and 16 threads, which can handle the game's simulation overhead while leaving headroom for the GPU to push frame rates.

Comparing to the nearest rivals in the CPU benchmarks, the 9800X3D scores 37,780 on average, sitting just 0.1% behind the Intel Xeon 6353P's 37,811 and 0.7% behind the Intel Core i5-13600KF's 38,028. These tiny deltas mean the CPU's ranking is essentially tied with several Intel parts, but the 3D V-Cache design likely matters more in this simulation genre than the raw benchmark scores suggest.

CPU Role

The AMD Ryzen 7 9800X3D brings 8 cores and 16 threads based on the Zen 5 architecture, running at a 4.70 GHz base clock and boosting to 5.20 GHz. The 96 MB of shared L3 cache is the defining feature, providing a massive pool of fast memory for the simulation's frequently-accessed data structures. The CPU's benchmark results show a strong scaling curve: the 3DMark 2-thread score of 2,394 climbs to 4,669 at 4 threads, 8,252 at 8 threads, and 10,081 at 16 threads. This near-linear scaling indicates the game's workload can effectively utilize additional threads, though the single-thread score of 1,212 in 3DMark and 4,800 in Cinebench R23 single-core show that per-core performance is equally critical.

In Cinebench R23, the multicore score of 34,004 versus the single-core score of 4,800 yields a ratio of about 7.1x, meaning the CPU scales to approximately 7 cores of effective performance. For a simulation game like Pc Building Simulator, which often has a primary simulation thread plus supporting threads, this profile is ideal. The PassMark physics score of 4,083 and integer math score of 116,709 suggest the CPU excels at the type of calculation-heavy work simulations require. The 90th percentile ranking against all CPUs, with an average benchmark score of 37,780, confirms this is a top-tier part, but the deltaPct values against rivals — all within -0.7% to -0.1% — show that the 9800X3D is not dramatically ahead of the nearest Intel competitors in raw aggregate benchmarks.

The data implies that the 9800X3D's advantage in this game comes less from raw compute and more from the 96 MB L3 cache, which reduces memory latency for the simulation's data sets. The 89.6 GB/s memory bandwidth and DDR5 dual-channel support provide a solid foundation, but the cache is what separates this CPU from the pack.

FAQ

Q: Why does the frame rate drop so much from 1080p to 4K at Low settings?

A: The average FPS falls from 446.7 at 1920x1080 to 172.4 at 3840x2160, a 61.4% reduction. This indicates the RTX 4090 becomes the bottleneck at 4K, as the GPU must render nearly four times as many pixels while the CPU's workload stays relatively constant.

Q: Is this combo overkill for Pc Building Simulator?

A: The combo ranks 19th out of 1,769 tested configurations, which is in the top 1.1%. While the game is a simulation title, the data shows this pairing delivers 79.9 FPS at 4K Ultra, meaning it never dips below a playable threshold even in the worst case.

Q: How does the CPU's cache affect performance in this game?

A: The 96 MB of shared L3 cache is the standout feature of the 9800X3D. Simulation games frequently access the same data structures, and the large cache keeps that data close to the cores, reducing stalls. The CPU's 3DMark scores show strong scaling from 2 threads (2,394) to 16 threads (10,081), suggesting the game can use multiple threads effectively.

Q: What is the best resolution for this combo?

A: At 2560x1440 High settings, the combo achieves 163.5 FPS, which is above the refresh rate of most high-end monitors. At 4K High, it drops to 87.1 FPS, still smooth but not maximizing the GPU's potential. The data suggests 1440p is the sweet spot for balancing visual quality and frame rate.

Q: Does the RTX 4090's 24 GB of VRAM matter at 4K?

A: The 24 GB of GDDR6X memory with 1.01 TB/s bandwidth ensures that texture streaming is never a limiting factor. The 4K Ultra result of 79.9 FPS indicates the GPU's memory subsystem handles the highest resolution and preset without throttling.

Q: How does this combo compare to the CPU's nearest rivals?

A: The 9800X3D's average benchmark score of 37,780 is within 0.7% of the Intel Core i5-13600KF's 38,028 and within 0.1% of the Intel Xeon 6353P's 37,811. These tiny deltas mean the CPU's performance is effectively tied with these parts, but the combo's rank 19 out of 1,769 suggests the 3D V-Cache provides a game-specific benefit.

GPU Role

The NVIDIA GeForce RTX 4090 is built on the AD102 chip with Ada Lovelace architecture, fabricated on TSMC's 5 nm process with 76,300 million transistors. The GPU runs at a 2235 MHz base clock and boosts to 2520 MHz, with memory clocked at 1313 MHz or 21 Gbps effective. The 24 GB of GDDR6X memory on a 384-bit bus delivers 1.01 TB/s of bandwidth, which is critical for high-resolution texture streaming in simulation games. The GPU's 16,384 shading units and 128 RT cores provide immense compute capacity, though Pc Building Simulator likely relies more on the traditional rasterization path.

The GPU's benchmark results show a PassMark G3D score of 38,194 and a Geekbench OpenCL score of 317,684, placing it in the 91st percentile against all GPUs. The nearest rivals in the GPU benchmarks show interesting deltas: the NVIDIA Tesla T4 scores 66,733 on average (0.4% higher), while the AMD Radeon Pro Vega 56 scores 67,097 (0.9% higher). These professional-grade cards edge out the RTX 4090 in aggregate benchmarks, but the 4090's gaming-focused design delivers the 79.9 FPS minimum seen at 4K Ultra in this title.

The GPU's role becomes evident when examining the FPS scaling across settings at each resolution. At 1080p, the difference between Low (446.7 FPS) and Ultra (248.6 FPS) is 198.1 FPS, showing the GPU has headroom even at the highest preset. At 4K, the same settings span from 172.4 FPS to 79.9 FPS, a 92.5 FPS range that shows the GPU working harder. The 5 nm process and 450 W TDP, with a suggested 850 W PSU, indicate this is a power-hungry part, but the performance data justifies the thermal and power requirements.

Settings Recommendations

The measured FPS values across all four settings presets provide a clear picture of the optimal configuration. At 1080p, even Ultra settings produce 248.6 FPS, which is far above any display's refresh rate, so choosing Ultra is the obvious recommendation for maximum visual fidelity without sacrificing smoothness. At 1440p, Ultra delivers 157.2 FPS, still exceptionally high, making it the best choice for high-refresh-rate monitors. At 4K, Ultra drops to 79.9 FPS, which is playable but not ideal for 120 Hz displays.

The data suggests that High settings at 4K (87.1 FPS) provide only a marginal improvement over Ultra (79.9 FPS), a mere 8.2 FPS gain. However, dropping to Medium at 4K (120.8 FPS) yields a substantial 50.9% improvement over Ultra, making Medium the recommended preset for 4K users who prioritize frame rate. The Low preset at 4K (172.4 FPS) offers the highest frame rate but likely sacrifices too much visual quality for the modest gains over Medium.

For most users, the sweet spot is Medium at 4K or Ultra at 1440p. The 1440p Ultra result of 157.2 FPS is high enough to drive 144 Hz monitors, while the 4K Medium result of 120.8 FPS suits 120 Hz displays. The 1080p results are so high across all settings (248.6 to 446.7 FPS) that any preset works, making Ultra the logical default.

Measured FPS Breakdown

At 1920x1080, the combo delivers 446.7 FPS on Low, 367.6 FPS on Medium, 257.5 FPS on High, and 248.6 FPS on Ultra. The gap between Low and Ultra is 198.1 FPS, and the drop from Medium to High is 110.1 FPS, showing that the High preset introduces a significant rendering cost.

At 2560x1440, performance scales to 327.4 FPS on Low, 230.7 FPS on Medium, 163.5 FPS on High, and 157.2 FPS on Ultra. The transition from 1080p to 1440p reduces frame rates by approximately 27% to 37% across presets, with the smallest relative loss at Low (26.7%) and the largest at High (36.5%).

At 3840x2160, the results are 172.4 FPS on Low, 120.8 FPS on Medium, 87.1 FPS on High, and 79.9 FPS on Ultra. The 1440p to 4K transition is steeper, with frame rates falling by 47.3% at Low and 49.2% at Ultra. The 4K Ultra result of 79.9 FPS is the only measured value below 100 FPS, indicating that this combo only begins to feel constrained at the absolute maximum settings and resolution. The progression from Low to Ultra at each resolution shows diminishing returns, with the largest single-step drop occurring from Low to Medium at 1080p (79.1 FPS) and from Medium to High at 1440p (67.2 FPS).
