Pc Building Simulator

Pc Building Simulator is a simulation title that scales unusually well with hardware, and the AMD Ryzen 7 5800X3D paired with the NVIDIA GeForce RTX 4080 SUPER produces a frame-rate curve that reveals a system with massive headroom at lower resolutions but a clear GPU ceiling at 4K. The data shows a 90th-percentile CPU and an 88th-percentile GPU working in tandem, with the measured FPS at each setting tier providing a clear picture of where this combination excels and where it starts to strain.

Resolution Scaling

The frame-rate drop from 1080p to 4K is steep and consistent, pointing directly at the graphics card as the primary limiter at higher resolutions. At Low settings, the average FPS falls from 324.7 at 1920x1080 to 279.1 at 2560x1440, then drops sharply to 154.3 at 3840x2160. That is a 52.5% reduction from 1080p to 4K, which is a classic sign of GPU-bound behavior—the CPU is feeding frames faster than the GPU can render them at the higher pixel count.

The pattern holds across all presets. At High settings, the average goes from 232.4 at 1080p down to 147.2 at 1440p, and then to 80 at 4K. At Ultra, the numbers are 221.1, 137.6, and 74.9 respectively. The relative drop between 1440p and 4K is consistently around 45-46% for High and Ultra, which is slightly less severe than the Low preset’s 44.7% drop, suggesting that as the settings load increases, the GPU’s compute and memory bandwidth become the bottleneck more uniformly.

What stands out is how close the 1080p and 1440p numbers are at Low settings. The difference between 324.7 and 279.1 is only 14%—a modest penalty for a resolution bump. This indicates that at Low settings, even at 1440p, the CPU’s 96 MB of shared L3 cache and 8-core/16-thread configuration are still able to keep pace. The real cliff appears when moving to 4K, where the RTX 4080 SUPER’s 16 GB of GDDR6X memory and 736.3 GB/s bandwidth are taxed heavily, and the average FPS falls below the 1440p Low result by more than 44%.

The implication for builders is straightforward: if the target is 4K, the RTX 4080 SUPER is the component doing the heavy lifting, and the 5800X3D is not holding it back at these settings. At 1080p and 1440p, the system is likely CPU-limited in lighter scenes, but the measured averages are so high that this is irrelevant for practical use.

FAQ

Q: What is the best resolution for this CPU/GPU combo in Pc Building Simulator?

A: The data shows 2560x1440 as the sweet spot. At High settings, the average FPS is 147.2, which is well above the 80 average at 4K Ultra. At 1440p Ultra, the average is 137.6, still comfortably playable, while 4K Ultra drops to 74.9—a borderline result for a fast-paced simulation.

Q: How does the Ryzen 7 5800X3D’s cache affect performance here?

A: The 5800X3D features 96 MB of shared L3 cache, which is unusually large for a desktop CPU. The benchmark results show that at 1080p Low, the average FPS is 324.7, and at 1080p Ultra it is 221.1. The high cache capacity likely helps maintain these high frame rates by reducing memory latency in a game that involves managing many objects and UI elements.

Q: Is the RTX 4080 SUPER overkill for this game?

A: At 1080p and 1440p, yes—the measured averages exceed 220 FPS at Ultra, and hit 324.7 at Low. At 4K, the card is more justified, with an 80 FPS average at High and 74.9 at Ultra. The 16 GB VRAM is ample for this title, but the card’s compute power is only fully utilized at 4K.

Q: What is the frame rate difference between Low and Ultra at 1440p?

A: At 2560x1440, Low produces an average of 279.1 FPS, while Ultra produces 137.6 FPS. That is a 51% reduction in average frame rate, showing that the Ultra preset nearly halves performance compared to Low, though both remain playable.

Q: How does this combo rank against other tested systems?

A: The combo ranks 179th out of 1769 tested combinations, placing it in the top 10.1% of all systems tested in this game. This is consistent with the CPU and GPU both being in the 83rd and 88th percentiles respectively.

Q: Can this system handle 4K with high refresh rate monitors?

A: At 4K High, the average is 80 FPS, and at Ultra it is 74.9. This is sufficient for a 60 Hz panel, but not enough for 144 Hz. For a 144 Hz 4K monitor, dropping to Medium settings raises the average to 111.9 FPS, which is closer to the target.

CPU Role

The AMD Ryzen 7 5800X3D is a Zen 3 part built on a 7 nm process, with 8 cores and 16 threads. Its base clock is 3.40 GHz, boosting to 4.50 GHz, and it has a 105 W TDP. The defining feature is the 96 MB shared L3 cache, which is triple the typical size for this architecture. In Pc Building Simulator, a game that simulates system assembly and likely involves many discrete objects and UI updates, this cache is a significant asset.

The benchmark scores for the CPU show a strong multithreaded profile: a 3DMark 16-thread score of 7299 and a max-thread score of 7285, with single-thread at 884. Cinebench R23 multicore hits 24063, while single-core is 3397. These numbers place the CPU in the 83rd percentile of all CPUs, with an average benchmark score of 26574. Its nearest rival, the AMD EPYC 8024P, scores 26555, a delta of 0.1%—essentially identical—while the Intel Core i9-11900K is also within 0.1%. The AMD Ryzen 5 7600 is 0.2% faster, and the Intel Core i9-12900HK is 0.4% faster.

In this game, the CPU’s role is to feed the GPU with draw calls and simulation updates. The measured FPS at 1080p Low (324.7) is far above what any GPU-bound scenario would produce, meaning the CPU is not the limiting factor at that resolution. The 16 threads and large cache allow for consistent frame delivery, and the data supports this: the gap between 1080p and 1440p at Low settings is only 14%, which is smaller than the gap between 1440p and 4K (44.7%). This pattern suggests the CPU is capable of pushing frame rates well beyond 300 FPS, and the GPU becomes the bottleneck only as pixel count rises.

How This Combo Ranks

The combination of the Ryzen 7 5800X3D and RTX 4080 SUPER ranks 179th out of 1769 tested combos in Pc Building Simulator. That places it in the top 10.1% of all systems tested, which is a strong result given the game’s simulation nature and the fact that many higher-ranked combos likely feature newer, more expensive CPUs and GPUs.

The CPU’s percentile rank of 83 and the GPU’s percentile of 88 are both high, but the system’s overall rank of 179 suggests that the pairing is well-balanced for this title. The nearest CPU rivals—such as the Intel Core i9-11900K and AMD Ryzen 5 7600—are within 0.4% of the 5800X3D’s average benchmark score, meaning that swapping the CPU for a slightly faster part would not drastically change the in-game FPS at 4K, where the GPU dominates. However, at 1080p, a faster CPU might push the average above 324.7, but the data does not show that here.

The GPU’s nearest rival, the AMD Radeon RX 6900 XT, is 0.2% slower in average benchmark score, while the RTX 5070 Ti is 2.9% faster. This indicates that the RTX 4080 SUPER is positioned near the top of the performance stack, and its 16 GB memory is more than enough for this game’s requirements. The rank of 179 out of 1769 is a practical indicator that this combo will handle the game with ease at most settings, but it is not the absolute fastest configuration available.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest averages. Low settings produce 324.7 FPS, Medium drops to 285.9, High comes in at 232.4, and Ultra is 221.1. The difference between Low and Ultra is 103.6 FPS, or 31.9% lower performance at Ultra. This resolution is clearly CPU-limited in lighter scenes, as the GPU is capable of far more than 324.7 FPS if the CPU could feed it.

At 2560x1440, the averages are 279.1 (Low), 207.5 (Medium), 147.2 (High), and 137.6 (Ultra). The drop from Low to Ultra is 141.5 FPS, a 50.7% reduction. The gap between High and Ultra is only 9.6 FPS, suggesting that Ultra adds visual fidelity without a massive performance penalty at this resolution.

At 3840x2160, the averages are 154.3 (Low), 111.9 (Medium), 80 (High), and 74.9 (Ultra). The spread from Low to Ultra is 79.4 FPS, a 51.4% reduction. Notably, the difference between High and Ultra at 4K is just 5.1 FPS, which makes Ultra the obvious choice for quality at 4K if the hardware can tolerate the slightly lower average.

The data shows a consistent pattern: at every resolution, the jump from Low to Medium costs about 20-25% performance, while the jump from High to Ultra costs only 3-6%. This suggests that the Ultra preset is not dramatically more demanding than High in this game, despite the visual improvements.

Settings Recommendations

For a 1080p display, the data shows that Ultra settings are an easy recommendation. The average FPS of 221.1 is far above any refresh rate on the market, and the difference from High (232.4) is negligible. Even at Low, the 324.7 average is pointless to chase unless chasing maximum frame times, but for normal use, Ultra is the clear choice.

At 1440p, the recommendation is Ultra as well. The 137.6 average is enough for a 144 Hz monitor, and the difference from High (147.2) is only 6.5%. If the display is a 165 Hz or 240 Hz panel, dropping to High would provide a more comfortable margin, but the data indicates that Ultra remains playable for most users.

At 4K, the choice depends on the display’s refresh rate. For a 60 Hz monitor, Ultra at 74.9 FPS is perfectly fine, and the visual quality is worth the 5.1 FPS penalty over High (80). For a 120 Hz or 144 Hz display, High is the better option, as it provides a 80 FPS average, while Medium offers 111.9 FPS for those who prefer higher frame rates over maxed-out settings. Low at 154.3 FPS is overkill for most, but the data shows it is available if needed.

Overall, the system is capable of running the game at maximum settings at 1080p and 1440p without concern. At 4K, the Ultra preset is viable for 60 Hz panels, and High or Medium are better suited for higher refresh rates. The measured FPS at 4K Medium (111.9) suggests that a compromise between quality and speed is achievable, making this combo flexible across all resolution tiers.
