Pc Building Simulator

# Pc Building Simulator — Intel Core i5-11400F + AMD Radeon RX 5700 XT

This combo delivers a playable but not overwhelming experience in Pc Building Simulator, sitting near the bottom quarter of tested configurations. The data shows a clear pattern: the pairing is capable of high frame rates at lower resolutions and settings, but falls below the 60 FPS threshold at 4K on higher presets. The benchmark results indicate a system that is balanced enough for 1080p and 1440p gaming, yet one that requires careful settings management for 4K displays. The combination ranks 1341 out of 1769 tested combos in this game, placing it in the 76th percentile of all configurations — a position that reflects its mid-range hardware heritage rather than any single bottleneck.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and reveals where the system's limits lie. At High settings, the average FPS falls from 109.7 at 1920x1080 to 70.6 at 2560x1440, then plummets to 39.8 at 3840x2160. That is a 36% reduction when moving from 1080p to 1440p, followed by a further 44% drop when stepping up to 4K. The scaling pattern is consistent across all settings presets, with the gap between 1440p and 4K being consistently larger than the gap between 1080p and 1440p.

This behavior points to the GPU as the primary limiting factor at higher resolutions. The RX 5700 XT, with its 8 GB of GDDR6 memory and 448.0 GB/s bandwidth, simply cannot maintain the pixel throughput required at 4K. The 256-bit memory bus and 64 ROPs are adequate for 1440p, but the data shows that 4K Ultra is nearly unplayable at 36.2 FPS. The scaling from Low to Ultra at each resolution shows a similar story: at 1080p, the difference between Low (222.5 FPS) and Ultra (103.7 FPS) is a 53% reduction, while at 4K the same settings span from 75.6 FPS down to 36.2 FPS — a 52% reduction. The consistency of this percentage suggests a balanced scaling curve, but the absolute numbers at 4K are simply too low for smooth gameplay.

GPU Role

The AMD Radeon RX 5700 XT is built on the RDNA 1.0 architecture with a Navi 10 chip manufactured on a 7 nm process. Its boost clock of 1905 MHz and game clock of 1755 MHz provide the raw compute power, with 2560 shading units and 160 texture mapping units feeding the 64 ROPs. The FP32 throughput of 9.754 TFLOPS is respectable, but the data shows it is not enough for 4K Ultra in this simulation title.

The 8 GB of GDDR6 memory on a 256-bit bus delivers 448.0 GB/s of bandwidth. This is sufficient for 1080p and 1440p at all settings, as evidenced by the frame rates above 67.6 FPS at 1440p Ultra. However, at 4K, the memory bandwidth becomes a constraint. The measured frame rates at 3840x2160 — 39.8 FPS High, 53.6 FPS Medium, and 36.2 FPS Ultra — all fall below the 60 FPS target, indicating that the GPU is saturated. The pixel rate of 121.9 GPixel/s and texture rate of 304.8 GTexel/s are simply not enough to fill 8.3 million pixels per frame at high quality settings.

The GPU's benchmark scores reinforce this analysis. Its PassMark G3D score of 16277 places it in the 68th percentile of all GPUs, and its nearest rivals — the NVIDIA RTX A5000 Mobile (0.1% faster), Intel Arc A350M (0.3% slower), and NVIDIA GeForce RTX 5060 Mobile (0.6% slower) — are all close in synthetic performance. Yet in this game, the 4K results show that real-world performance lags behind what those synthetic numbers might suggest for a simulation workload.

CPU Role

The Intel Core i5-11400F provides six cores and twelve threads with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. This Rocket Lake-S processor, built on Intel's 14 nm process, delivers solid multi-threaded performance with a Cinebench R23 multi-core score of 14372 and a single-core score of 2029. Its PassMark single-thread score of 2981 and multi-thread score of 16908 show a balanced CPU that is not the bottleneck in this game.

The CPU's 12 MB of shared L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are adequate for Pc Building Simulator's simulation mechanics. The game's genre suggests CPU-bound scenarios, but the data does not support that hypothesis here. The frame rate scaling from 1080p to 4K is almost entirely GPU-driven, with no evidence of a CPU ceiling. At 1080p Low, the system reaches 222.5 FPS, which is far above the refresh rate of most monitors and demonstrates that the i5-11400F can feed the GPU efficiently.

The CPU's nearest rivals — AMD Ryzen 7 5700U (0% difference), Intel Core i7-1260P (0.2% faster), and Intel Core Ultra 7 164U (0.2% faster) — show that the i5-11400F is competitive with newer mobile parts in synthetic benchmarks. Its 75th percentile ranking among all CPUs means it outperforms the majority of processors, and in this game, it is clearly not the limiting factor at any resolution or settings combination.

Measured FPS Breakdown

At 1920x1080, the system delivers excellent performance across all settings. Low settings produce 222.5 FPS, Medium yields 154.8 FPS, High achieves 109.7 FPS, and Ultra still manages 103.7 FPS. All of these are above the 60 FPS threshold, and even Ultra is smooth on a 144 Hz monitor. The jump from High to Ultra is modest — a 5.5% reduction — suggesting diminishing returns from the highest quality preset.

At 2560x1440, the performance remains strong but begins to show strain. Low settings hit 138.3 FPS, Medium achieves 98.2 FPS, High reaches 70.6 FPS, and Ultra drops to 67.6 FPS. The gap between High and Ultra narrows to 4.2%, but the drop from Medium to High is a more significant 28.1%. For 1440p gaming, High settings are the practical ceiling for maintaining a 60+ FPS experience.

At 3840x2160, the system struggles. Low settings produce 75.6 FPS, which is playable, but Medium drops to 53.6 FPS, High falls to 39.8 FPS, and Ultra bottoms out at 36.2 FPS. The scaling from Low to Medium is a 29.1% reduction, and from Medium to High another 25.7% loss. At 4K, only Low settings provide a consistently smooth experience, and even that is close to the 60 FPS line.

How This Combo Ranks

The combo ranks 1341 out of 1769 tested configurations in Pc Building Simulator, placing it in the 76th percentile — meaning 76% of tested combos outperform it. This is a low ranking for a CPU that sits in the 75th percentile and a GPU in the 68th percentile individually. The gap between component rankings and the combo's in-game rank suggests that Pc Building Simulator is particularly demanding on the GPU at high resolutions, or that the game favors configurations with more modern architectures.

The CPU's nearest rivals in synthetic benchmarks — the Ryzen 7 5700U, Core i7-1260P, and Core Ultra 7 164U — all score within 0.2% of the i5-11400F, yet the in-game rank shows this combo underperforms relative to what those synthetic scores might predict. Similarly, the GPU's nearest rivals are all within 0.9% of the RX 5700 XT in average benchmark score, yet the 4K results here are below what a top-30% GPU should deliver in a simulation title.

This ranking indicates that the combo is best suited for 1080p or 1440p gaming, where its performance exceeds the needs of most users. The 4K results, while technically playable on Low settings, are not competitive with other configurations in the database.

Settings Recommendations

Based on the measured frame rates, the optimal experience depends entirely on the target resolution. For 1080p displays, Ultra settings at 103.7 FPS provide the best visual quality with no sacrifice in smoothness. The 5.5% difference between High and Ultra is worth taking for the improved visuals.

For 1440p displays, High settings at 70.6 FPS offer the best balance of quality and performance. Ultra is only 4.2% slower at 67.6 FPS, so either preset works well, but High leaves more headroom for demanding scenes. Medium at 98.2 FPS is the choice for competitive play or high-refresh-rate monitors.

For 4K displays, Low settings at 75.6 FPS are the only viable option for smooth gameplay. Medium at 53.6 FPS is borderline playable, but the frame pacing issues that come with sub-60 FPS performance make it a poor choice. High and Ultra are not recommended at 4K, as the 39.8 FPS and 36.2 FPS results fall well below the acceptable threshold for a simulation game where precision matters.

The data suggests that this combo is a 1080p champion and a 1440p workhorse, but it is not a 4K solution. Users with 4K displays should either lower resolution scaling or accept Low settings. The 8 GB of VRAM and the GPU's compute capabilities are simply not enough for this game's higher presets at 4K resolution.
