Pc Building Simulator with Intel Core i5-9400 + AMD Radeon RX 580, In-Depth Analysis
This analysis examines the measured performance of the Intel Core i5-9400 paired with the AMD Radeon RX 580 in Pc Building Simulator. The data set provides a clear picture of how this combination behaves across standard resolutions and quality presets. The results show a system that is decisively more capable at lower resolutions, with its performance envelope collapsing as the pixel count climbs. The following sections break down the bottleneck dynamics, the role of each component, and the optimal settings for this pairing.
Resolution Scaling
The measured frames per second reveal a steep performance cliff as resolution increases. At 1920x1080 with Low settings, the combo produces 119.5 FPS. Moving to 2560x1440 at the same Low preset drops the average to 78.8 FPS, a reduction of roughly one-third. The decline continues to 3840x2160, where the average settles at 40.9 FPS. This pattern indicates that the rendering load scales heavily with pixel count, and the RX 580's compute resources are the primary constraint.
At High settings, the scaling is equally pronounced. The 1080p result is 60.5 FPS, which falls to 38 FPS at 1440p and then to 18.4 FPS at 4K. The gap between 1080p and 1440p is 22.5 FPS, while the gap between 1440p and 4K is 19.6 FPS. This near-linear degradation suggests the GPU is saturated at every step, with no headroom to absorb the extra pixel workload. The Ultra preset tells a similar story: 55.4 FPS at 1080p, 33.5 FPS at 1440p, and 18.5 FPS at 4K. The 4K Ultra result is effectively unplayable, and even the 4K Medium figure of 27.8 FPS is marginal.
The data indicates that this system is firmly a 1080p performer. At 1440p, only the Low preset reaches the 60 FPS threshold, while High and Ultra fall below 40 FPS. The transition from 1080p to 1440p incurs a 30-40% performance penalty across presets, while the jump to 4K roughly halves the already reduced frame rates. The limiting component is clearly the GPU, as the CPU's six cores and six threads are unlikely to be the bottleneck at these low frame rates, particularly in a simulation title where the scene complexity is moderate.
GPU Role
The AMD Radeon RX 580 features 8 GB of GDDR5 memory on a 256-bit bus, providing a bandwidth of 256.0 GB/s. Its base clock is 1257 MHz with a boost clock of 1340 MHz, and the memory runs at 2000 MHz or 8 Gbps effective. The card has 2304 shading units, 144 texture mapping units, and 32 render output units. These specifications place it in the mid-range segment, and its benchmark scores reflect that positioning.
In Pc Building Simulator, the GPU's VRAM capacity is sufficient for the game's demands, as the simulation does not typically require massive texture buffers. The limiting factor is more likely the raw compute throughput, rated at 6.175 TFLOPS FP32. The 4K results, where even Low settings only yield 40.9 FPS, suggest the shader units are overwhelmed by the pixel count. The 8 GB VRAM is not the constraint; if it were, we would see a more pronounced difference between Low and Ultra at the same resolution. Instead, the drop from Low to Ultra at 1080p is from 119.5 FPS to 55.4 FPS, indicating a fill-rate or shader-bound scenario.
The GPU's percentile ranking among all tested graphics cards is 53, placing it just above the median. Its nearest rivals in aggregate benchmark score include the NVIDIA GeForce GTX 570 and the GTX 950, with delta percentages of 0 and 0.1, respectively. This contextualizes the RX 580 as a capable but not exceptional part. In this specific game, the measured data shows it can comfortably handle 1080p at Medium settings, achieving 86.6 FPS, but struggles to maintain playable frame rates at higher resolutions.
How This Combo Ranks
The combination of the Intel Core i5-9400 and the AMD Radeon RX 580 is ranked 1651 out of 1769 tested combos in Pc Building Simulator. This places it in the bottom 7% of all configurations, which is a poor showing. The rank reflects that most other CPU-GPU pairings deliver higher average frame rates at the tested settings. The low rank is notable because the individual components are not at the very bottom of their respective benchmark charts.
The CPU's average benchmark score is 2305, which places it at the 50th percentile of all CPUs. Its nearest rivals include the Intel Core i3-10305 with a score of 2300 and a delta of 0.2, and the Intel Core i7-8809G with a score of 2319 and a delta of -0.6. The GPU's average benchmark score is 13559, at the 53rd percentile of all GPUs. Despite these mid-pack individual scores, the combo ranks poorly, suggesting that this particular game favors other hardware combinations, perhaps due to specific driver optimizations or the game's reliance on certain architectural features.
The rank of 1651 out of 1769 is a decisive metric. It indicates that in a database of thousands of combinations, this pairing is near the bottom for Pc Building Simulator. This is not a reflection of the components being defective, but rather that they are outperformed by the vast majority of alternatives. For context, the delta percentages against the GPU's nearest rivals are all within 1.1%, so the RX 580 is not an outlier in its class. The poor combo rank is more likely a function of the game's modest requirements, where even lower-end parts can achieve high frame rates, pushing this combo down the list.
FAQ
Q: What is the best resolution for this combo in Pc Building Simulator?
A: The data shows that 1920x1080 is the only resolution where the system consistently achieves playable frame rates. At 1080p, all four tested presets exceed 55 FPS, with Low at 119.5 FPS and Medium at 86.6 FPS. At 1440p, only the Low preset reaches 78.8 FPS, while High and Ultra fall to 38 FPS and 33.5 FPS, respectively.
Q: How much performance is lost when moving from 1080p to 4K at High settings?
A: The average frame rate drops from 60.5 FPS at 1920x1080 to 18.4 FPS at 3840x2160 at High settings. This represents a reduction of 42.1 FPS, which is a 70% decrease in performance. The system is not suited for 4K gaming in this title.
Q: Is the 8 GB VRAM on the RX 580 sufficient for this game?

A: The AMD Radeon RX 580 has an average benchmark score of 13559. Its nearest rival is the NVIDIA GeForce GTX 570 with a score of 13564, showing a delta of 0. The NVIDIA GeForce GTX 950 is also close with a score of 13549 and a delta of 0.1.
CPU Role
The Intel Core i5-9400 is a six-core, six-thread processor with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. It has 9 MB of shared L3 cache and supports dual-channel DDR4 memory, with a memory bandwidth of 42.7 GB/s. In Pc Building Simulator, the CPU's role is less critical than the GPU, as evidenced by the frame rate scaling with resolution.
At 1080p Low, the system achieves 119.5 FPS, which is a high enough frame rate that the CPU might start to become a factor. However, the single-core and multi-core benchmark scores, such as 1125 in Cinebench R23 single-core and 7969 in multi-core, indicate a competent processor. The CPU's percentile ranking is 50, meaning it is exactly average among all tested CPUs. Its nearest rival, the Intel Core i3-10305, has an average score of 2300, which is a 0.2 delta from the i5-9400's 2305.
The data suggests that the CPU is not the primary bottleneck in this game. If it were, we would see less variation in frame rates across resolutions, as the CPU workload would remain constant. Instead, the frame rates drop significantly from 1080p to 4K, which is a classic sign of GPU limitation. The CPU's six threads are sufficient for the game's simulation logic, and its boost clock of 4.10 GHz provides adequate single-thread performance for game logic. The 65W TDP and 14 nm process are not directly relevant to gaming performance but indicate an efficient part.
Settings Recommendations
Based on the measured data, the optimal settings for this combo depend on the target frame rate. For a smooth 60 FPS experience at 1080p, the High preset delivers 60.5 FPS, which is just above the threshold. The Medium preset provides more headroom at 86.6 FPS, making it the better choice for maintaining a stable frame rate with some margin for demanding scenes. The Low preset at 119.5 FPS is the highest frame rate available, but it comes with a visual quality sacrifice that may not be necessary.
For 1440p, the choices are more constrained. The Low preset achieves 78.8 FPS, which is playable, but the Medium preset drops to 52.7 FPS, which is below the 60 FPS target. High and Ultra at 1440p are not recommended, as they yield 38 FPS and 33.5 FPS, respectively. At 4K, no preset is recommended for a good experience; the best result is 40.9 FPS on Low, which is still below the playable threshold.
The best experience per the measured rows is 1080p with the Medium preset. This setting provides a balance between visual fidelity and performance, achieving 86.6 FPS. It offers a significant improvement over the High preset's 60.5 FPS while retaining better visuals than Low. For users with a 1440p monitor, the Low preset is the only viable option for smooth gameplay, but the compromise in visual quality may not be worth it. Overall, this system is best utilized at 1080p, where it can deliver a responsive and visually acceptable experience without pushing the GPU to its limits.
