Pc Building Simulator

The Intel Core i5-11400F paired with the AMD Radeon RX 7900 XT delivers a decisive 4K experience in Pc Building Simulator, though the data reveals a clear shift in bottleneck behavior as resolution climbs. At 1080p, the combo is heavily CPU-limited, with frame rates exceeding 300 FPS at Low settings, while at 4K, the GPU becomes the primary constraint, with Ultra settings dropping to 64.4 FPS. This system ranks 389th out of 1,769 tested combinations, placing it in the top 22% of all configs for this title.

Resolution Scaling

The scaling pattern from 1080p to 4K is stark and reveals the limiting component at each step. Moving from 1080p High (200.9 FPS) to 1440p High (125 FPS) represents a 37.8% performance drop, while the jump from 1440p High to 4K High (63.7 FPS) is a further 49.0% reduction. This nonlinear decline indicates that the RX 7900 XT’s raw compute is the bottleneck at higher resolutions, not the i5-11400F’s six cores.

At 1080p, the CPU ceiling is evident: Low settings produce 298.5 FPS, but Ultra only yields 190.2 FPS, a 36.3% gap that suggests the processor cannot feed the GPU fast enough even at lower graphical loads. The 1440p results confirm this—Low hits 251.6 FPS, while Ultra manages 117.4 FPS, showing a 53.3% reduction. By 4K, the GPU takes over entirely: Low delivers 128.4 FPS, Medium 91.7 FPS, High 63.7 FPS, and Ultra 64.4 FPS. The near-identical High and Ultra scores at 4K indicate the GPU is saturated, with the 20 GB VRAM buffer preventing any memory-related stutter.

FAQ

*Q: Can this combo run Pc Building Simulator at 4K Ultra?*

A: Yes, but barely. The measured 4K Ultra average is 64.4 FPS, which is playable but not high-refresh. The 4K High result (63.7 FPS) is nearly identical, suggesting Ultra adds little visual cost but also no headroom.

Q: Is the Intel Core i5-11400F a bottleneck at 1080p?

A: Yes. At 1080p Low, the system reaches 298.5 FPS, but at 1080p Ultra it drops to 190.2 FPS. This 36.3% gap is far larger than the GPU’s 4K scaling, indicating the CPU limits frame rates when the GPU is not under full load.

Q: How does the RX 7900 XT’s 20 GB VRAM affect 4K performance?

A: The 20 GB GDDR6 memory with 800.0 GB/s bandwidth ensures that texture-heavy scenes at 4K do not hit memory limits. The 4K Ultra score of 64.4 FPS confirms the bottleneck is shader throughput, not VRAM capacity.

Q: What is the best resolution for maximizing frame rate?

A: 1440p offers the best balance. At 1440p High, the system delivers 125 FPS, which is 96% higher than 4K High and still 37.8% lower than 1080p High, but with significantly better image quality than 1080p.

Q: How does this combo rank against other tested systems?

A: It ranks 389th out of 1,769 tested combos, placing it in the 78th percentile. This is above average, but the ranking is dragged down by the CPU’s 75th percentile score versus the GPU’s 82nd percentile.

Q: Does the i5-11400F’s lack of overclocking matter for this game?

A: No. The multiplier is locked, but the measured FPS at 1080p (298.5 FPS Low) is already far beyond any display refresh rate, so additional CPU headroom would not improve the gaming experience.

Settings Recommendations

The optimal preset depends on the target resolution, but the data strongly favors High settings for balanced visual fidelity and performance. At 4K, High (63.7 FPS) and Ultra (64.4 FPS) are statistically identical, so choosing High avoids any unnecessary GPU strain without sacrificing visual quality. The 1.1 FPS difference between them is negligible, and High likely reduces power draw on the 300 W TDP card.

At 1440p, High (125 FPS) is the sweet spot, delivering 6.5% more performance than Ultra (117.4 FPS) while still looking superior to Medium (175.6 FPS). The Medium preset at 1440p is a viable option for high-refresh monitors, but the visual downgrade from High is not worth the extra 50.6 FPS unless the display is 165 Hz or faster. At 1080p, Low (298.5 FPS) is pointless for most users since even Ultra (190.2 FPS) exceeds typical 144 Hz displays. Medium (265.5 FPS) is the best choice for 240 Hz panels, while High (200.9 FPS) is the maximum sensible setting for 165 Hz screens.

How This Combo Ranks

The combination ranks 389th out of 1,769 tested configurations, which places it in the top 22% of all systems benchmarked for Pc Building Simulator. This is a strong showing, but the rank is asymmetric: the GPU’s 82nd percentile (vs all GPUs) is notably higher than the CPU’s 75th percentile (vs all CPUs). This imbalance means the i5-11400F holds back the RX 7900 XT in CPU-bound scenarios, particularly at 1080p where the frame rates exceed 200 FPS.

Relative to the GPU’s nearest rivals, the RX 7900 XT scores 38,358 on average, matching the NVIDIA GeForce RTX 5080 Mobile (38,349, 0% delta) and outperforming the NVIDIA CMP 70HX (38,225, 0.3% delta) and RTX 4080 Mobile (38,135, 0.6% delta). The CPU’s nearest rivals are similarly tight: the i5-11400F averages 17,181, essentially tied with the AMD Ryzen 7 5700U (17,189, 0% delta) and Intel Core i7-1260P (17,212, -0.2% delta). This data shows the combo is built around a GPU that punches above its CPU partner’s weight.

GPU Role

The AMD Radeon RX 7900 XT is the dominant component in this pairing, and its benchmark data confirms it. The GPU scores 29,009 in Passmark G3D and 16,828 in GPU Compute, with a 3DMark Steel Nomad DX12 score of 5,623. These figures place it in the 82nd percentile of all GPUs, and its 20 GB GDDR6 memory on a 320-bit bus provides 800.0 GB/s of bandwidth—sufficient for 4K textures without spillover.

The clock behavior explains the 4K scaling. The base clock is 1,387 MHz, boosting to 2,394 MHz, with a game clock of 2,025 MHz. At 4K, the GPU’s 5,376 shading units and 336 texture mapping units are fully engaged, producing 51.48 TFLOPS of FP32 performance. The 192 ROPs deliver a pixel rate of 459.6 GPixel/s, which is why the 4K Ultra score (64.4 FPS) is only slightly below the 4K High score (63.7 FPS)—the ROP throughput is the limiting factor, not the shading units. The GPU’s 84 ray accelerators are irrelevant here since Pc Building Simulator does not use ray tracing, but the 12 Ultimate (12_2) API support ensures full DirectX 12 compatibility.

Measured FPS Breakdown

The complete dataset shows a clear progression across resolutions and settings. At 1080p, Low delivers 298.5 FPS, Medium 265.5 FPS, High 200.9 FPS, and Ultra 190.2 FPS. At 1440p, the same settings produce 251.6 FPS, 175.6 FPS, 125 FPS, and 117.4 FPS, respectively. At 4K, the scores are 128.4 FPS (Low), 91.7 FPS (Medium), 63.7 FPS (High), and 64.4 FPS (Ultra).

The 1440p to 4K transition is particularly revealing. At 1440p Low, the system hits 251.6 FPS, but 4K Low drops to 128.4 FPS—a 49.0% reduction that mirrors the 1440p High to 4K High drop (125 to 63.7 FPS, 49.0%). This consistent halving across all settings confirms the GPU is the sole bottleneck at 4K. Conversely, the 1080p to 1440p transition shows a smaller drop for Low settings (298.5 to 251.6 FPS, 15.7%) versus High settings (200.9 to 125 FPS, 37.8%), indicating the CPU can still partially compensate at lower graphical loads.

CPU Role

The Intel Core i5-11400F is a six-core, 12-thread processor with a base clock of 2.60 GHz and a boost of 4.40 GHz. Its benchmark results are respectable but not exceptional: Cinebench R23 multicore scores 14,372, while Geekbench multicore hits 7,579. The single-thread scores (Cinebench R23: 2,029, Geekbench: 1,979) are adequate for simulation games, but the 75th percentile ranking versus all CPUs shows it is a mid-range part.

In Pc Building Simulator, the CPU’s role is most visible at 1080p, where frame rates exceed 200 FPS. The 3DMark 16-thread score of 5,619 and max-thread score of 5,652 indicate the processor can handle multiple simulation threads, but the gap between 1080p Low (298.5 FPS) and 1080p Ultra (190.2 FPS) suggests the 12 MB L3 cache and 14 nm process limit sustained throughput when the GPU is not the constraint. The 65 W TDP and locked multiplier mean the processor cannot be pushed further, but this is irrelevant given that even at 1440p High (125 FPS), the system comfortably exceeds 60 FPS. The CPU’s 51.2 GB/s memory bandwidth on dual-channel DDR4 is sufficient for this game’s data streaming, as evidenced by the stable 4K scores.
