# Pc Building Simulator with Intel Core i5-14400F + AMD Radeon RX 6750 XT

Pc Building Simulator, the 2019 simulation title, presents an unusual test scenario for the Intel Core i5-14400F paired with the AMD Radeon RX 6750 XT. With measured data across three resolutions and four settings presets, the combination reveals distinct performance characteristics. The data shows a system that scales predictably with resolution, but the shape of that scaling curve tells a deeper story about where the bottleneck lies. This pairing, ranking 847th out of 1769 tested combos, sits roughly in the middle of the database — a position that invites investigation into whether the CPU or GPU is driving the results.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and consistent across all settings, but the magnitude of that drop varies significantly. At Low settings, the average frame rate falls from 281.4 FPS at 1920x1080 to 95.1 FPS at 3840x2160 — a reduction to roughly one-third of the original value. This is a steep decline that points strongly toward GPU limitation at higher resolutions. At Medium settings, the drop is from 201.6 FPS down to 66.1 FPS, again roughly a third. The High preset shows a similar pattern: 141.4 FPS at 1080p dropping to 45.4 FPS at 4K, which is almost exactly a 68% reduction. Ultra settings follow the same trajectory, falling from 136.7 FPS to 46.6 FPS.

What makes this scaling profile interesting is the consistency of the ratio. Whether the workload is light (Low) or heavy (Ultra), the 4K to 1080p ratio hovers around 0.33 to 0.34. This uniformity suggests that the limiting component — the GPU — is being stressed in a predictable manner as pixel count quadruples. The RX 6750 XT, with its 12 GB of GDDR6 memory and 432.0 GB/s bandwidth, appears to be the primary constraint in this equation. The CPU, with its 10 cores and 16 threads, likely has headroom to spare, especially at lower resolutions where frame rates exceed 200 FPS.

The 1440p results reinforce this interpretation. At Low settings, the system produces 176.1 FPS at 2560x1440, which sits between the 1080p and 4K values in a way that tracks pixel count almost linearly. The same pattern holds for Medium (124.5 FPS), High (91.7 FPS), and Ultra (83.4 FPS). This clean scaling behavior indicates a well-balanced system in terms of memory bandwidth and processing power, but one where the GPU's rendering capabilities are the ceiling at higher resolutions.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with a Navi 22 chip, fabricated on a 7 nm process by TSMC. Its 2560 shading units, 160 TMUs, and 64 ROPs provide the raw compute necessary for this simulation game's visual output. The boost clock of 2600 MHz and game clock of 2495 MHz are competitive figures, and the 13.31 TFLOPS of FP32 performance gives the card substantial headroom for pixel processing.

The memory subsystem is particularly relevant to Pc Building Simulator's performance. The 12 GB of GDDR6 memory on a 192-bit bus delivers 432.0 GB/s of bandwidth. This is crucial because the game's benchmark results show that even at 4K Ultra, the system maintains 46.6 FPS — a playable figure for a simulation title. The VRAM capacity appears sufficient, as the data does not show any catastrophic drops that would indicate memory exhaustion at higher resolutions. The card's performance in synthetic benchmarks — a Passmark G3D score of 20700 and a 3DMark Steel Nomad DX12 score of 2548 — aligns with its measured in-game results, placing it in the 79th percentile of all GPUs.

Interestingly, the nearest rivals for this GPU include the NVIDIA GeForce RTX 3080, which has an average benchmark score only 1.3% higher. This proximity in synthetic scores does not necessarily translate to identical in-game performance, but it contextualizes the RX 6750 XT's position. The card's pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s are the specs that likely govern its behavior in this simulation-heavy title, where rendering many on-screen components and interfaces is the norm.

FAQ

Q: Is the Intel Core i5-14400F the bottleneck at 1080p Low settings?

A: The data suggests not entirely. At 1920x1080 Low, the system achieves 281.4 FPS, which is exceptionally high. The CPU's Cinebench R23 multicore score of 21914 and single-core score of 3093 indicate strong processing capability. However, the 1080p results being roughly triple the 4K results at every setting level implies the GPU is still the limiting factor, even at lower resolutions.

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

A: The combination ranks 847th out of 1769 tested combos, placing it in the 48th percentile. This is a below-median position, which is notable given the individual components' percentiles — the CPU sits in the 88th percentile while the GPU is in the 79th. The middling rank suggests that this particular pairing may not extract the full potential from either component in Pc Building Simulator.

Q: What is the best resolution for a smooth experience?

A: For a 60 FPS target, 2560x1440 at High settings delivers 91.7 FPS, which is comfortably above the threshold. Even 4K at Medium settings achieves 66.1 FPS, making it viable for players who prioritize visual fidelity. The 1080p results are all above 136 FPS, so any setting at that resolution will provide a fluid experience.

Q: Does the RX 6750 XT's 12 GB VRAM cause any issues?

A: The measured data shows no evidence of VRAM-related stuttering or frame rate anomalies. The 4K Ultra result of 46.6 FPS is consistent with the scaling trend from lower settings, indicating that the 432.0 GB/s bandwidth and 12 GB capacity are sufficient for this game's demands at these resolutions.

Q: How does the CPU compare to its nearest rivals?

A: The i5-14400F has an average benchmark score of 32508, which places it nearly identical to the Intel Core i7-12800H (0% delta). It is 0.2% ahead of the AMD Ryzen 5 PRO 7645 and 0.2% behind both the AMD Ryzen 7 250 and Intel Core i7-13705H. This tight grouping suggests the CPU's performance is well-established in this range.

Q: Is the 46.6 FPS at 4K Ultra playable?

A: For a simulation game like Pc Building Simulator, which does not require twitch reflexes, 46.6 FPS is arguably acceptable. However, dropping to High settings at 4K yields 45.4 FPS — nearly identical — so the Ultra preset does not cost much performance here. The 4K Medium setting at 66.1 FPS offers a better balance for smoother gameplay.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all presets. Low settings produce an average of 281.4 FPS, which is a remarkably high figure that suggests the GPU is nowhere near saturation. Medium settings drop to 201.6 FPS, still far above display refresh rate capabilities. High settings yield 141.4 FPS, and Ultra settings reduce the average to 136.7 FPS. Notably, the gap between High and Ultra at 1080p is only 4.7 FPS, indicating diminishing returns from the highest preset.

Moving to 2560x1440, the frame rates remain strong but show more differentiation between presets. Low settings average 176.1 FPS, which is still exceptionally smooth. Medium drops to 124.5 FPS, High to 91.7 FPS, and Ultra to 83.4 FPS. The spread between Low and Ultra at 1440p is 92.7 FPS, a wider margin than at 1080p, reflecting the increased GPU workload.

At 3840x2160, the performance curve flattens considerably. Low settings average 95.1 FPS, which is a playable figure. Medium settings drop to 66.1 FPS, and High settings to 45.4 FPS. Ultra settings produce 46.6 FPS, which is actually slightly higher than High — a minor anomaly that could be attributed to measurement variance or specific scene complexity. The 4K results show that this combo can handle the resolution, but only at lower presets for a consistently smooth experience.

How This Combo Ranks

The combo's rank of 847 out of 1769 tested configurations places it just below the midpoint of the database. This is a curious outcome when considering the individual component strengths. The i5-14400F's 88th percentile ranking among all CPUs and the RX 6750 XT's 79th percentile among GPUs would suggest a higher combined position, yet the in-game results tell a different story.

This disconnect might be explained by the nature of Pc Building Simulator itself. As a simulation game focused on PC assembly rather than action, its rendering demands may not align perfectly with the strengths of this hardware combination. The game's release in 2019 predates both components, which means it was not optimized for their specific architectures. The CPU's nearest rivals — the i7-12800H, Ryzen 5 PRO 7645, and Ryzen 7 250 — all have nearly identical average scores, yet the system's ranking indicates that game-specific factors override raw compute capability.

The GPU's nearest rivals include the RTX 5070 Ti Mobile and RTX 3080, with delta percentages within 1.3%. This suggests the RX 6750 XT is in good company for synthetic benchmarks, but the in-game ranking of 847th shows that Pc Building Simulator's workload does not necessarily reward the card's specific feature set. For players considering this combo, the ranking serves as a reference point rather than a definitive quality judgment.

Settings Recommendations

For players targeting 60 FPS as a baseline, the data points to 1440p Medium or High as the optimal balance. At 2560x1440 Medium, the system delivers 124.5 FPS, which provides significant headroom above the 60 FPS threshold. High settings at the same resolution yield 91.7 FPS, still well above target. Both options offer a smooth experience while allowing for visual improvements over Low settings.

At 4K resolution, the choice becomes more constrained. Medium settings at 66.1 FPS are the only preset that reliably exceeds 60 FPS. High and Ultra settings both fall below 50 FPS, which may be acceptable for a simulation title but could feel less responsive. Low settings at 95.1 FPS are an option for players who prioritize frame rate above all else, but the visual fidelity loss is substantial.

For 1080p users, the situation is more forgiving. Any preset produces frame rates above 136 FPS, so the recommendation is to use Ultra settings for the best visual experience without sacrificing smoothness. The 4.7 FPS difference between High and Ultra at this resolution makes the highest preset essentially free in performance terms. The data also shows that the step from Medium to High costs 60.2 FPS at 1080p, which is a significant drop, but the resulting 141.4 FPS is still excellent.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor from the Raptor Lake architecture, running on Intel Socket 1700. Its base clock of 2.50 GHz and boost clock of 4.70 GHz provide substantial single-thread performance, as evidenced by its Cinebench R23 single-core score of 3093. The 20 MB of shared L3 cache and 1.25 MB per-core L2 cache contribute to responsive performance in simulation workloads.

In Pc Building Simulator, the CPU's role appears secondary to the GPU based on the scaling data. The fact that frame rates drop by roughly two-thirds when moving from 1080p to 4K across all settings strongly suggests the GPU is the primary bottleneck. However, the CPU's performance in multitasking and physics calculations — reflected in its Passmark multithread score of 25783 and data compression score of 317725 — ensures that the game's simulation aspects do not become a limiting factor.

The processor's 65 W TDP and 10 nm process node make it an efficient choice, though this efficiency does not directly translate to gaming performance. Its nearest rival, the Intel Core i7-12800H, has an identical average benchmark score, which underscores that the i5-14400F's performance tier is well-established. The CPU's 88th percentile ranking among all CPUs indicates it is a strong performer overall, even if Pc Building Simulator does not fully leverage its capabilities. The data suggests that for this specific game, the CPU has ample headroom, and any performance gains would need to come from GPU upgrades rather than processor changes.
