Pc Building Simulator

Pc Building Simulator is a simulation title that rarely stresses high-end hardware, but the measured results for the Intel Core i5-13400F and NVIDIA GeForce RTX 4080 combo show a fascinating shift in bottleneck behavior across resolutions. At 1080p, the CPU is clearly the limiting factor, but by 4K, the GPU takes over, creating a predictable scaling curve that highlights the strengths and limits of this pairing.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep but consistent, revealing how the workload transitions from CPU-bound to GPU-bound. At Ultra settings, the combo delivers 224 FPS at 1080p, which falls to 141 FPS at 1440p and then to 74 FPS at 4K. That is a 34% reduction from 1080p to 1440p, and another 48% drop from 1440p to 4K. The pattern is nearly identical at High settings: 235 FPS at 1080p, 148 FPS at 1440p, and 78 FPS at 4K.

The most telling data point comes from the Low settings preset. At 1080p Low, the combo hits 366 FPS, but at 1440p Low it only drops to 297 FPS, and at 4K Low it still manages 155 FPS. The relatively small gap between 1080p and 1440p Low (366 vs 297 FPS) suggests that the CPU is holding the system back at lower resolutions. If the GPU were the sole bottleneck, the difference would be much larger, as the pixel count increases by 78% between those two resolutions. Instead, the i5-13400F’s 10 cores and 16 threads are saturated by the game’s simulation logic, capping performance well below what the RTX 4080 could deliver.

At 4K, the situation flips. The jump from 155 FPS at Low to 110 FPS at Medium and then 78 FPS at High shows the GPU becoming the primary constraint. The RTX 4080’s 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are sufficient, but the raw compute load at 3840x2160 begins to tax the 9728 shading units. The delta between 4K Medium (110 FPS) and 4K Ultra (74 FPS) is 33%, which aligns with the GPU’s workload scaling rather than CPU limits.

Notably, the only measured minimum and maximum frame times appear at Medium settings across all resolutions. At 1080p Medium, the range is 274–370 FPS, at 1440p Medium it is 179–242 FPS, and at 4K Medium it is 93–126 FPS. This suggests that Medium is the sweet spot where neither component is completely maxed out, allowing for more consistent frame pacing. The absence of min/max data for Low, High, and Ultra presets means those settings likely exhibit more variance, though the average scores remain stable.

How This Combo Ranks

Within the benchmark database, this specific CPU-GPU pairing ranks 278th out of 3723 tested combos for Pc Building Simulator. That places it in the top 7.5% of all configurations, which is impressive for a mid-range CPU paired with a high-end GPU. The rank reflects the game’s moderate hardware demands—it is not a graphically intensive title, so the RTX 4080’s raw power is somewhat wasted, but the i5-13400F’s strong multi-threaded performance helps maintain high frame rates.

The CPU’s average benchmark score of 25292 places it in the 77th percentile of all processors. Its nearest rival, the AMD Ryzen 9 6900HS, scores 25284, a delta of 0%. The Intel Core 5 120 and AMD Ryzen 5 5600X3D both score slightly higher at 25362 and 25365 respectively, showing a -0.3% delta. The AMD Ryzen 7 6800H trails at 25201, a 0.4% delta. This clustering indicates that the i5-13400F is firmly in the upper-midrange tier, trading blows with mobile flagship chips and desktop X3D parts.

For the GPU, the RTX 4080’s average score of 54247 puts it in the 86th percentile of all graphics cards. Its nearest rival, the RTX 4080 SUPER, scores 54209 with a 0.1% delta, meaning the two are nearly identical in synthetic benchmarks. The AMD Radeon Pro W5700X scores 54828 (-1.1%), while the RX 6750 GRE 12 GB scores 55698 (-2.6%). The RTX 4080 is clearly a top-tier GPU, but its performance in Pc Building Simulator is constrained by the game’s low graphical demands.

The combo rank of 278 suggests that while the RTX 4080 is overkill for this title, the i5-13400F is a capable partner. Many higher-ranked combos likely use faster CPUs, but the difference in real-world FPS is minimal given the game’s simulation-heavy nature. The data shows that this pairing is well-balanced for 1440p and 4K gaming, even if it is not the absolute best configuration.

FAQ

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

A: The data shows 1440p as the sweet spot. At High settings, it delivers 148 FPS, which is 90% of the 1080p score (235 FPS) while offering significantly more screen detail. At 4K High, performance drops to 78 FPS, which is still playable but not ideal for high-refresh monitors.

Q: How much faster is the RTX 4080 than its closest rival, the RTX 4080 SUPER?

A: The RTX 4080 scores 54247 in average benchmarks, while the RTX 4080 SUPER scores 54209. The delta is 0.1%, meaning the RTX 4080 is actually slightly ahead by 38 points, a negligible difference in real-world gaming.

Q: Does the i5-13400F bottleneck the RTX 4080 at 1080p?

A: Yes. At 1080p Low, the combo hits 366 FPS, but at 1440p Low it only drops to 297 FPS. The 19% reduction from 1080p to 1440p is far less than the 78% pixel increase, indicating the CPU limits performance before the GPU becomes fully utilized.

Q: What is the frame time variance at Medium settings?

A: The only measured min/max values are at Medium. At 1080p, the range is 274–370 FPS (average 322), at 1440p it is 179–242 FPS (average 210), and at 4K it is 93–126 FPS (average 110). These ranges suggest stable frame pacing across all resolutions.

Q: How does this combo rank compared to other tested configurations?

A: It ranks 278th out of 3723 combos, putting it in the top 7.5% of all tested pairs. The CPU is in the 77th percentile and the GPU in the 86th percentile, so the combo is stronger than the average pairing.

Q: Is the RTX 4080 overkill for this game?

A: Given that 4K Ultra delivers 74 FPS and 1080p Ultra delivers 224 FPS, the GPU has ample headroom. The game’s simulation genre does not heavily utilize graphics features, so a lower-tier GPU would likely achieve similar results, but the RTX 4080 ensures no frame rate drops are CPU-related.

Measured FPS Breakdown

At 1920x1080, the combo delivers exceptional performance across all settings. Low settings produce 366 FPS, Medium produces 322 FPS (with a measured range of 274–370), High produces 235 FPS, and Ultra produces 224 FPS. The difference between High and Ultra is just 11 FPS, suggesting diminishing returns from the highest preset.

Moving to 2560x1440, the frame rates remain impressive. Low hits 297 FPS, Medium averages 210 FPS (range 179–242), High averages 148 FPS, and Ultra averages 141 FPS. The gap between High and Ultra narrows to just 7 FPS, indicating that the Ultra preset’s additional effects have minimal impact at this resolution.

At 3840x2160, the GPU begins to show its limits. Low still manages 155 FPS, but Medium drops to 110 FPS (range 93–126), High to 78 FPS, and Ultra to 74 FPS. The difference between High and Ultra is only 4 FPS, while the jump from Low to Medium is 45 FPS, showing that the GPU’s compute resources are the bottleneck at 4K.

The scaling pattern is consistent: Low to Medium provides the largest FPS boost at every resolution, while High to Ultra yields marginal gains. For example, at 1080p, the difference between Low (366) and Medium (322) is 44 FPS, while High (235) to Ultra (224) is only 11 FPS. This suggests that Medium is the most efficient preset for balancing visual quality and performance.

Settings Recommendations

Based on the measured data, the Medium preset offers the best experience for this combo. At 1440p, Medium delivers 210 FPS with a narrow frame time range (179–242), which is ideal for smooth gameplay. The High preset at 1440p drops to 148 FPS, a 30% reduction that is noticeable on high-refresh monitors but still playable. Ultra at 1440p yields 141 FPS, barely better than High and not worth the extra visual settings.

For 4K users, Medium is again the recommended choice. It produces 110 FPS with a stable range (93–126), while High drops to 78 FPS and Ultra to 74 FPS. The 36 FPS gap between Medium and High at 4K is significant, and the visual differences in a simulation game are unlikely to justify the performance loss. Low at 4K (155 FPS) is an option for competitive play, but the graphical quality reduction may be too severe for a game focused on visual detail.

At 1080p, the choice is less critical. High (235 FPS) and Ultra (224 FPS) are nearly identical, so Ultra is fine if the monitor supports it. However, Medium (322 FPS) provides a 97 FPS boost over Ultra, which could be beneficial for 240Hz displays. Low (366 FPS) is unnecessary unless chasing absolute maximum frame rates.

The data suggests that Medium is the sweet spot across all resolutions, offering the best balance of frame rate and visual fidelity. The measured min/max values at Medium also indicate more consistent frame pacing, which is crucial for a simulation game where stutters can disrupt gameplay.

CPU Role

The Intel Core i5-13400F features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. This Raptor Lake-S chip has a 20 MB shared L3 cache and supports DDR4 and DDR5 memory. Its synthetic benchmarks show strong multi-threaded performance: Cinebench R23 multicore scores 22604, while single-core scores 3191. Geekbench multicore hits 11068, and Passmark multithread scores 25032.

In Pc Building Simulator, the CPU’s role is significant due to the game’s simulation mechanics. The low-resolution results (1080p Low at 366 FPS) indicate that the CPU is the primary bottleneck at lower settings. The 16 threads are likely utilized for simulating PC components, and the 4.60 GHz boost clock helps maintain high frame rates in less demanding scenes. The 3DMark scores support this interpretation: the 16-thread score of 7314 is nearly identical to the max-thread score of 7307, showing excellent scaling across all cores.

At 4K, the CPU’s influence diminishes. The frame rates at 4K Low (155 FPS) versus 4K Ultra (74 FPS) show a 52% drop, which is driven by GPU load rather than CPU limits. The RTX 4080’s 48.74 TFLOPS FP32 performance and 280.6 GPixel/s pixel rate become the limiting factors. However, the CPU still needs to feed the GPU with enough draw calls, and the i5-13400F’s 3DMark 8-thread score of 5591 suggests it can handle the simulation overhead without stuttering.

Compared to its nearest rivals, the i5-13400F is well-positioned. It matches the AMD Ryzen 9 6900HS (0% delta) and slightly trails the Ryzen 5 5600X3D (-0.3%). The Ryzen 7 6800H is 0.4% behind. This means the CPU’s performance in Pc Building Simulator is consistent with its synthetic scores, and it does not exhibit any unusual behavior in this specific game. The 65W TDP and 10 nm process node make it an efficient choice, though the RTX 4080’s 320W TDP dominates the system’s power draw.

The combination of 10 cores and a high boost clock is well-suited for a simulation game that likely uses multiple threads for logic but still benefits from fast single-thread performance for physics or UI updates. The CPU’s 77th percentile ranking among all processors confirms it is above average, but not top-tier, which explains why it occasionally bottlenecks the RTX 4080 at 1080p.
