Pc Building Simulator

Pc Building Simulator pairs a 6-core Intel Core i5-11400F with the flagship NVIDIA GeForce RTX 5090, and the measured results show a combination that is heavily skewed toward GPU performance. This is a simulation title that scales almost linearly with graphics card capability, and the RTX 5090 dominates the frame rate charts at every resolution and preset. The data indicates that the CPU, while competent, is not the limiting factor in this specific pairing. The measured frames per second (FPS) across all tested configurations reveal a system that can push well past 200 FPS at 1080p, remain fluid at 1440p, and only begin to show strain at 4K with higher quality settings. The benchmark results suggest that this combo is best treated as a high-refresh-rate 1440p machine, or a very capable 4K60 setup when settings are tuned appropriately.

Settings Recommendations

The measured FPS data provides a clear picture of which preset offers the best experience for this hardware combination. At 1920x1080, the difference between Low and Ultra is a drop from 302.7 FPS to 230.1 FPS, which is a 24% performance penalty for the highest visual quality. Given that even the Ultra preset at 1080p delivers 230.1 FPS, there is no reason to use lower settings at this resolution. The data shows that the Ultra preset is the optimal choice for 1080p, as it fully utilizes the high refresh rate potential without sacrificing visual fidelity.

At 2560x1440, the picture becomes more nuanced. The Low preset hits 260.7 FPS, while Ultra drops to 163.6 FPS. The Medium preset at 228.6 FPS and High at 168.6 FPS bracket the range. For a 1440p monitor with a 144Hz refresh rate, the Medium preset is the sweet spot, delivering 228.6 FPS which is more than enough to saturate any standard high-refresh display. The Ultra preset at 163.6 FPS still exceeds 144Hz, so it is also viable, but the Medium preset provides headroom and smoother frame pacing at a 40% higher frame rate than Ultra.

At 3840x2160, the RTX 5090 starts to feel the pressure. The Low preset achieves 175 FPS, which is excellent, but the Medium preset drops to 123.4 FPS, and High falls to 88.5 FPS. The Ultra preset bottoms out at 84.8 FPS. For a 4K gaming experience, the Medium preset at 123.4 FPS is the best balance, providing a smooth 100+ FPS experience while maintaining acceptable visuals. The High preset at 88.5 FPS is still playable but sits just below the 90 FPS threshold, making Medium the clear recommendation for 4K.

GPU Role

The NVIDIA GeForce RTX 5090 is the dominant component in this pairing, and its specifications align directly with the measured performance. The GPU features 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. This memory configuration is far more than any simulation game needs at these resolutions, which explains why the FPS drops are so consistent across settings rather than being limited by memory capacity. The 32 GB frame buffer means that even at 4K Ultra, the game is not competing for VRAM, allowing the GPU to focus entirely on compute.

The clock speeds are also a factor. The base clock of 2017 MHz and boost clock of 2407 MHz, combined with 21760 shading units, produce a raw compute capability of 104.8 TFLOPS FP32. This massive compute throughput is what drives the high frame rates at 1080p and 1440p. The benchmark data shows that the RTX 5090 maintains a 302.7 FPS average at 1080p Low, which reflects its ability to brute-force through draw calls and physics calculations in a simulation environment. The GPU's 176 ROPs and 680 TMUs handle the pixel and texture work efficiently, but the real story is the raw shader performance. The fact that the GPU scores 39650 in Passmark G3D and 380114 in Geekbench OpenCL confirms its position in the 94th percentile of all GPUs, and this translates directly to the measured FPS in this game.

The RTX 5090's nearest rivals in the benchmark database include the RTX 5090 D (0.1% delta), the RTX 5050 Mobile (0.2% delta), and the AMD Radeon PRO W6600 (1.3% delta). These are all close in average benchmark scores, but the RTX 5090's 32 GB memory and higher clock speeds make it particularly suited for this simulation title where frame pacing matters more than raw peak compute.

How This Combo Ranks

This specific combination of the Intel Core i5-11400F and NVIDIA GeForce RTX 5090 ranks 131 out of 1769 tested combos in Pc Building Simulator. That places it in the top 7.4% of all configurations tested for this game. The percentile ranking is strong, but it is not at the absolute top, which suggests that there are faster CPU options that could push this GPU even higher. The CPU has a percentile ranking of 75 against all CPUs, meaning it is better than 75% of processors tested, but it is not a top-tier chip. The GPU, by contrast, sits in the 94th percentile of all GPUs.

The gap between the CPU and GPU percentiles is telling. The i5-11400F scores 14372 in Cinebench R23 multicore and 2029 in single-core, which puts it in the same performance class as the AMD Ryzen 7 5700U (0% delta) and the Intel Core i7-1260P (-0.2% delta). These are mobile-oriented processors, which highlights that the i5-11400F is a mid-range desktop chip. In a simulation game that is not heavily multithreaded, the CPU still keeps up, but the rank of 131 out of 1769 suggests that pairing this GPU with a higher-end CPU would yield better results. The data shows that this combo is GPU-bound in most scenarios, but at 1080p Low where the FPS hits 302.7, the CPU may become a limiting factor.

Measured FPS Breakdown

The measured FPS data provides a complete picture across three resolutions and four quality presets. At 1920x1080, the results are: Low 302.7 FPS, Medium 264.1 FPS, High 234.2 FPS, and Ultra 230.1 FPS. The step from Medium to High is a 12% drop, while High to Ultra is only a 1.8% drop, indicating that the Ultra preset adds very little visual cost at 1080p.

At 2560x1440, the numbers are: Low 260.7 FPS, Medium 228.6 FPS, High 168.6 FPS, and Ultra 163.6 FPS. The drop from Medium to High is a significant 26.3%, which is the largest single-step penalty in this resolution. This suggests that the High preset introduces some heavy effects that scale poorly. The Ultra preset at 163.6 FPS is only 3% slower than High, making High a poor value choice compared to Ultra.

At 3840x2160, the results are: Low 175 FPS, Medium 123.4 FPS, High 88.5 FPS, and Ultra 84.8 FPS. The drop from Low to Medium is 29.5%, and from Medium to High is 28.3%. The step from High to Ultra is only 4.2%, which again shows that Ultra is not much more demanding than High. The 4K numbers are the most telling: the RTX 5090 can deliver over 120 FPS at Medium, but falls below 90 FPS at High and Ultra.

Resolution Scaling

The FPS drop from 1080p to 4K reveals the bottleneck characteristics of this combo. At Low settings, the scaling is: 302.7 FPS at 1080p, 260.7 FPS at 1440p, and 175 FPS at 4K. This is a 13.9% drop from 1080p to 1440p, and a 32.9% drop from 1440p to 4K. The 4K resolution demands 2.25 times the pixel count of 1440p, but the FPS only drops by a third, indicating that the GPU is still not fully saturated.

At Ultra settings, the scaling is: 230.1 FPS at 1080p, 163.6 FPS at 1440p, and 84.8 FPS at 4K. The drop from 1080p to 1440p is 28.9%, and from 1440p to 4K is 48.2%. The 4K Ultra result of 84.8 FPS is the only sub-100 FPS figure in the entire dataset. This scaling pattern shows that the GPU is the limiting component at Ultra settings, but at Low settings, the CPU begins to matter more. The fact that 1080p Low (302.7 FPS) is only 16% faster than 1440p Low (260.7 FPS) suggests that the CPU is holding back the GPU at lower resolutions. At 4K, the GPU is fully engaged, and the scaling becomes more linear with pixel count.

FAQ

Q: Is the RTX 5090 overkill for Pc Building Simulator at 1080p?

A: The data shows that at 1080p Ultra, the combo achieves 230.1 FPS, which is far beyond any standard 60Hz or 144Hz monitor. The RTX 5090 is not overkill if you are targeting 240Hz or 360Hz displays, but for typical monitors, the GPU is heavily underutilized at this resolution.

Q: What is the best resolution for this combo to maintain 100+ FPS?

A: The measured data shows that at 2560x1440 with Ultra settings, the combo delivers 163.6 FPS, and at 3840x2160 with Medium settings, it delivers 123.4 FPS. Both configurations maintain over 100 FPS, making 1440p Ultra and 4K Medium the recommended targets.

Q: How does the i5-11400F compare to its nearest rivals in this game?

A: The i5-11400F has an average benchmark score of 17181, which is essentially tied with the AMD Ryzen 7 5700U (17189, 0% delta) and the Intel Core i7-1260P (17212, -0.2% delta). This means the CPU performance is comparable to those chips, but the combo rank of 131 out of 1769 indicates that other CPUs may pair better with the RTX 5090.

Q: Does the 32 GB VRAM on the RTX 5090 affect performance in this game?

A: The RTX 5090 has 32 GB of GDDR7 memory, but Pc Building Simulator does not appear to be VRAM-limited. The FPS scaling from 1080p to 4K is consistent across settings, and the GPU's compute power (104.8 TFLOPS) is the primary driver of performance, not memory capacity.

Q: Why is the FPS drop from 1440p to 4K larger at Ultra settings than at Low settings?

A: At Ultra settings, the FPS drops from 163.6 FPS at 1440p to 84.8 FPS at 4K, a 48.2% reduction. At Low settings, the drop is from 260.7 FPS to 175 FPS, a 32.9% reduction. This indicates that Ultra settings load the GPU more heavily, making pixel count the dominant factor, while at Low settings, the CPU bottleneck at lower resolutions becomes apparent.

Q: Can this combo run 4K at High settings smoothly?

A: The measured FPS at 3840x2160 High is 88.5 FPS. This is above 60 FPS but below 90 FPS, so it is playable on a standard 60Hz display but may not be ideal for a 120Hz or 144Hz 4K monitor. The Medium preset at 123.4 FPS is a better choice for high-refresh 4K.
