Pc Building Simulator

Pc Building Simulator is a simulation title that stresses both CPU and GPU in ways that become clear when looking at the measured frame rates for the AMD Ryzen 9 5900X and NVIDIA GeForce RTX 4080. The data indicates a system that is overwhelmingly GPU-limited at higher resolutions, but which still delivers very high frame rates even at 4K. The 5900X, with 12 cores and 24 threads, provides ample headroom, while the RTX 4080, with 16 GB of GDDR6X memory and a 256-bit bus, handles the heavy lifting. This page breaks down how this specific pairing scales across resolutions and settings, where the CPU matters, and what the measured FPS numbers mean in practice.

Resolution Scaling

Resolution scaling with this combo is dramatic and predictable. At 1920x1080 with Low settings, the average frame rate is 349 FPS. Moving to 2560x1440 at Low drops that to 297 FPS, a reduction of about 15%. At 3840x2160, Low yields 155 FPS, which is a 56% drop from the 1080p Low figure. This pattern is consistent with the GPU becoming the primary limiter as pixel count rises.

The 1080p to 4K scaling is most pronounced at Medium settings. At 1920x1080 Medium, the average is 310 FPS. At 2560x1440 Medium, it falls to 210 FPS, and at 3840x2160 Medium, it is 110 FPS. That represents a 65% reduction from 1080p to 4K. The Low settings row shows an even steeper relative drop from 1440p to 4K: from 309 FPS to 155 FPS, a 50% decline. This indicates that at 1080p, the CPU is still able to feed frames quickly, but the RTX 4080 is already being pushed hard at 4K.

The High settings data reinforces the same story. At 1920x1080 High, the average is 235 FPS. At 2560x1440 High, it is 148 FPS. At 3840x2160 High, it is 78 FPS. That is a 67% drop from 1080p to 4K, which is a very large reduction. The Ultra preset produces 224 FPS at 1080p, 141 FPS at 1440p, and 74 FPS at 4K. The 4K Ultra result of 74 FPS is still well within playable territory, but the scaling curve shows that this game is almost purely GPU-bound at higher resolutions. The CPU’s 12-core, 24-thread configuration is not the limiting factor at any resolution; the GPU can only produce so many frames per second as the render load grows.

The 4K Medium row is the only one with min and max FPS recorded: 93 and 126 FPS, with an average of 110. The 4K High and 4K Ultra rows have no min/max values, but the averages of 78 and 74 FPS respectively suggest that the game is hitting a wall around 74-78 FPS at Ultra settings. The 1440p Medium row has min/max of 179 and 242 FPS, and the 1080p Medium row has 261 and 353 FPS. These minimums show that even in heavier scenes, the frame rate stays high enough for smooth gameplay. The data shows that the RTX 4080 is the driving component for this game, and the 5900X is never the bottleneck at any tested resolution.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, codenamed Vermeer. It is built on TSMC’s 7 nm process and fits the AMD Socket AM4. The base clock is 3.70 GHz with a boost clock of 4.80 GHz, and it has a TDP of 105 W. The CPU has 64 MB of L3 cache, 512 KB of L2 cache per core, and 64 KB of L1 cache per core. Its memory support is DDR4 with a dual-channel bus, delivering a peak bandwidth of 51.2 GB/s. The processor supports PCIe Gen 4.

In this game, the CPU’s role is to feed the GPU with draw calls and physics calculations. The data suggests that the 5900X is more than sufficient. At 1080p Low, the frame rate reaches 349 FPS, which is a very high number that indicates the CPU is not holding back. Even when the resolution drops to 4K, the frame rate is limited by the GPU, not the CPU. The 5900X’s single-thread performance is strong, with a Cinebench R23 single-core score of 1527 and a multi-core score of 16262. Its Geekbench single-core score is 2083, and multi-core is 14118.

The 5900X has 12 cores and 24 threads, which is more than enough for a simulation game that likely uses multiple threads for building and management tasks, but the frame rate is not particularly CPU-sensitive at lower resolutions. The benchmark results show a clear pattern: the higher the resolution, the more the GPU dominates the frame rate. The 5900X is not the limiting component at any resolution tested. Its percentile rank among all CPUs is 87, which means it performs better than 87% of tested CPUs. Its average benchmark score is 41376, and it sits at a 0.3% difference from its nearest rival, the Intel Core Ultra 7 366H, which means the 5900X is a solidly mid-top-tier processor.

The 5900X’s boost clock of 4.80 GHz is high for a 12-core chip, and this helps with single-thread performance. The game’s engine may rely on a few threads for certain tasks, and the 5900X’s ability to boost to 4.80 GHz on a single core is beneficial. However, the overall frame rate is dictated by the GPU, so the CPU’s clock speed is not the main factor in the measured FPS differences.

How This Combo Ranks

The combination of the AMD Ryzen 9 5900X and NVIDIA GeForce RTX 4080 ranks 314th out of 3723 tested combos in Pc Building Simulator. That places it in the top 8.4% of all tested combinations. This rank reflects the overall performance of the CPU and GPU working together, and it is a very good result. The 5900X has an average benchmark score of 41376, and the RTX 4080 has an average score of 54247, but the in-game rank takes into account real-world FPS data.

Being at rank 314 out of 3723 means there are many combos that are faster, but also many that are slower. The position is largely determined by the RTX 4080’s GPU power, which is high. The RTX 4080 scores a percentile of 86 among GPUs, and the 5900X scores 87 among CPUs. These are both above-average parts, and their combination is strong.

The nearest rivals for the 5900X are all within 0.5% of its average score, meaning the CPU is not a differentiator. The RTX 4080’s nearest rival is the RTX 4080 SUPER, which is only 0.1% faster. Therefore, the rank of 314 is mostly a function of the GPU choice. The in-game results show that this combo can hit 349 FPS at 1080p Low and 155 FPS at 4K Low, and 74 FPS at 4K Ultra, which are all playable and smooth.

There are 3723 combos tested, and this one is in the top 10%, which is a strong position. The data suggests that the 5900X is not a weak link in this setup; the RTX 4080 is the primary driver of performance. For someone who wants to play Pc Building Simulator at high frame rates, this combo is more than adequate.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings levels. At 1920x1080:

• Low: 349 FPS average
• Medium: 310 FPS average, with min 261 FPS and max 353 FPS
• High: 235 FPS average
• Ultra: 224 FPS average

At 2560x1440:

• Low: 309 FPS average
• Medium: 210 FPS average, with min 179 FPS and max 242 FPS
• High: 148 FPS average
• Ultra: 141 FPS average

At 3840x2160:

• Low: 155 FPS average
• Medium: 110 FPS average, with min 93 FPS and max 126 FPS
• High: 78 FPS average
• Ultra: 74 FPS average

The 1080p numbers are extremely high, with the lowest setting producing 349 FPS and the highest setting producing 224 FPS. The gap between Low and Ultra at 1080p is 125 FPS, which is a 36% reduction. At 1440p, the gap between Low and Ultra is 168 FPS (309 to 141), a 54% reduction. At 4K, the gap is 81 FPS (155 to 74), a 52% reduction. This indicates that the GPU is heavily stressed at 4K, but even at Ultra, the frame rate is still above 70 FPS, which is smooth for a simulation game.

The Medium settings at each resolution provide the most complete data. The 1080p Medium has a min of 261 FPS and max of 353 FPS, showing a range of 92 FPS. The 1440p Medium has a min of 179 and max of 242, a 63 FPS range. The 4K Medium has a min of 93 and max of 126, a 33 FPS range. The smaller range at higher resolutions suggests the GPU is more consistently maxed out, with less variance. The frame data shows that this combo can handle high-refresh-rate monitors at 1080p and 1440p, and even at 4K, it can maintain a good experience.

Settings Recommendations

For a 1080p monitor, the Ultra preset is not necessary. The data shows that at 1080p Ultra, the average FPS is 224, while at High it is 235 FPS and at Medium it is 310 FPS. Since the game is a simulation, the difference between High and Ultra may be small, but the 310 FPS at Medium is a significant jump over Ultra’s 224 FPS. If you have a 240Hz monitor, Medium or High would be the best choices to take advantage of the high refresh rate. The 349 FPS at Low is overkill and may not be worth the visual sacrifice.

For a 1440p monitor, the Medium preset provides an average of 210 FPS, with a min of 179 FPS, which is smooth. High gives 148 FPS, and Ultra gives 141 FPS. For a 144Hz to 165Hz monitor, High or Ultra are fine, but Medium will push the frame rate higher and will still look good. The 210 FPS at Medium is a solid choice if you want to use a high-refresh-rate 1440p panel. The 141 FPS at Ultra is also playable, but it is close to the lower limit for a 144Hz monitor.

For a 4K monitor, the Medium preset is the sweet spot. It produces an average of 110 FPS, with a min of 93 FPS, which is well above 60 FPS. High gives 78 FPS, and Ultra gives 74 FPS. The difference between High and Ultra is only 4 FPS, so there is little reason to use Ultra unless you want the highest visual quality. The 4K Medium at 110 FPS is very smooth and is the best performance-per-visual trade-off. The Low setting at 4K gives 155 FPS, but the visual degradation is likely too much for a simulation game where you look at detailed building parts.

In general, the data suggests that Medium settings at any resolution provide a strong balance, with the 1080p Medium delivering 310 FPS, 1440p Medium delivering 210 FPS, and 4K Medium delivering 110 FPS. The Ultra preset is only 74 FPS at 4K, which is still playable, but the Medium is the recommended choice for a high-refresh experience. The only caveat is that the 4K Low at 155 FPS is very high, but the visual quality will be low, so it is better to use Medium. The measured FPS data shows that this combo can handle any settings, but the smart choice is to use Medium at 4K, High at 1440p, and Medium or High at 1080p, depending on your monitor’s refresh rate.
