# Pc Building Simulator: Intel Core i5-11400F + AMD Radeon RX 7800 XT

The measured performance data for Pc Building Simulator with this combination reveals a system that scales predictably across resolutions and settings, with the AMD Radeon RX 7800 XT clearly dominating the workload. At 1080p Ultra, the combo delivers 155.8 FPS, while dropping to 4K Ultra reduces that to 51.8 FPS — a 67% reduction. The data suggests this is a GPU-bound scenario at higher resolutions, but at lower settings the CPU begins to show its influence. The Intel Core i5-11400F, with 6 cores and 12 threads, provides adequate throughput for a simulation title that rarely stresses more than a few threads, though the gap between Low and Ultra settings at each resolution hints at where the bottleneck shifts.

Resolution Scaling

The FPS drop from 1080p to 4K is steep but consistent across all settings, indicating that the GPU is the primary limiting factor at higher resolutions. At Low settings, the frame rate falls from 298.2 FPS at 1080p to 210.8 FPS at 1440p (a 29% drop), and then to 107.2 FPS at 4K (a 64% drop from 1080p). This pattern — relatively mild scaling from 1080p to 1440p, followed by a dramatic decline at 4K — is typical of a GPU that has ample headroom at lower pixel counts but becomes saturated as pixel count quadruples.

At High settings, the scaling is even more pronounced: 167.5 FPS at 1080p, 104 FPS at 1440p (a 38% drop), and 56.1 FPS at 4K (a 67% drop from 1080p). The Ultra preset shows the most severe degradation, with 155.8 FPS at 1080p falling to 101.9 FPS at 1440p (a 35% drop) and then to 51.8 FPS at 4K (a 67% drop from 1080p). Interestingly, the percentage loss from 1440p to 4K is nearly identical across all settings — roughly 46-49% — which suggests that the GPU's compute and memory bandwidth are the binding constraints once pixel count exceeds 1440p.

The data implies that at 1080p, even Ultra settings leave the RX 7800 XT underutilized, allowing the i5-11400F's 4.40 GHz boost clock to keep pace. At 4K, however, the GPU's 624.1 GB/s memory bandwidth and 37.32 TFLOPS FP32 throughput are the deciding factors, with the CPU's role diminishing significantly. The 16 GB GDDR6 frame buffer is never a limiting factor at these resolutions, as the game's modest texture requirements are easily satisfied.

Settings Recommendations

The measured rows reveal that the Medium preset offers the most balanced experience across all resolutions. At 1080p Medium, the combo achieves 235.9 FPS — 41% higher than High (167.5 FPS) and 51% higher than Ultra (155.8 FPS), while the visual difference between Medium and High is typically minor in a simulation title. At 1440p Medium, 145.1 FPS is well above the 60 FPS threshold, and even at 4K Medium, 77 FPS provides smooth gameplay.

Ultra settings, by contrast, deliver diminishing returns. At 4K Ultra, the 51.8 FPS average dips below the 60 FPS target, making it unsuitable for smooth play on high-refresh-rate displays. The High preset at 4K (56.1 FPS) is similarly marginal. For players prioritizing frame rate stability over visual fidelity, Medium at 1440p or 1080p offers the best trade-off. The data shows that Low settings provide minimal benefit at 1080p (298.2 FPS) and 1440p (210.8 FPS) — these frame rates exceed any typical display's refresh rate, making the visual quality sacrifice unnecessary. At 4K Low (107.2 FPS), the gain over Medium (77 FPS) is substantial, but the visual degradation in a game about building PCs may hinder readability of component details.

GPU Role

The AMD Radeon RX 7800 XT's 16 GB of GDDR6 memory on a 256-bit bus delivers 624.1 GB/s of bandwidth, which appears sufficient for Pc Building Simulator's asset streaming even at 4K Ultra. The GPU's 96 ROPs and 3840 shading units provide ample fill-rate and compute throughput, as evidenced by the 233.3 GPixel/s pixel rate and 37.32 TFLOPS FP32 performance.

The clock behavior is informative: the GPU's base clock of 1295 MHz, game clock of 2124 MHz, and boost clock of 2430 MHz show a wide dynamic range. The measured FPS values suggest the GPU is operating near its game clock in most scenarios, given that the scaling from Medium to Ultra is roughly linear (e.g., 77 FPS at 4K Medium vs. 51.8 FPS at 4K Ultra — a 33% drop for a 33% increase in settings complexity). The passmark G3D score of 24176 and the 3DMark Steel Nomad DX12 score of 4157 position this GPU in the 76th percentile of all GPUs, indicating strong but not flagship-level performance.

The GPU's memory clock of 2438 MHz (19.5 Gbps effective) is a notable asset for this game, as simulation titles often have unpredictable memory access patterns. The 28,100 million transistors on a 346 mm² die at 5 nm provide the efficiency needed to sustain high clocks without thermal throttling, though the 263 W TDP means adequate cooling is required. The nearest rivals — AMD FirePro S9300 X2, NVIDIA P104-100, NVIDIA T600 Mobile, and AMD FirePro S10000 — all score within 0.7% of the RX 7800 XT's average benchmark score of 32619, but none of these are modern gaming GPUs, underscoring the RX 7800 XT's position in the current market.

A: Its average benchmark score of 32619 is within 0.7% of the AMD FirePro S9300 X2, NVIDIA P104-100, NVIDIA T600 Mobile, and AMD FirePro S10000 — though these are largely workstation or older parts.

How This Combo Ranks

The Intel Core i5-11400F + AMD Radeon RX 7800 XT combination ranks 664th out of 1769 tested combos for Pc Building Simulator, placing it in the 62nd percentile. This is a solid mid-tier ranking, reflecting the GPU's strength (76th percentile of all GPUs) paired with a CPU that sits in the 75th percentile of all CPUs. The CPU's average benchmark score of 17181 is nearly identical to its nearest rivals — the AMD Ryzen 7 5700U (17189, 0% delta), Intel Core i7-1260P (17212, -0.2%), Intel Core Ultra 7 164U (17215, -0.2%), and Intel Core i5-1240U (17141, 0.2%) — indicating that the i5-11400F is not a performance outlier.

The ranking suggests that while the GPU is capable of high frame rates, the overall combo is held back by the CPU in CPU-light scenarios at lower resolutions. At 1080p Ultra, the 155.8 FPS result is impressive, but it is not in the top tier of combos that might exceed 200 FPS at this setting. The gap between Low and Ultra at 1080p (298.2 vs. 155.8 FPS) is 48%, which shows that the GPU has significant headroom that the CPU cannot fully exploit. This ranking also implies that players seeking higher frame rates at 1080p would benefit more from a stronger CPU than a stronger GPU, while those targeting 4K would see minimal gains from a CPU upgrade.

CPU Role

The Intel Core i5-11400F brings 6 cores and 12 threads based on the Rocket Lake architecture, with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. Its 12 MB of shared L3 cache and per-core L1 (80 KB) and L2 (512 KB) caches provide ample low-latency storage for Pc Building Simulator's simulation logic. The CPU's memory bandwidth of 51.2 GB/s over dual-channel DDR4 is a potential constraint, though the game's data access patterns appear to not heavily stress this.

The benchmark data shows this CPU's multithreaded performance is solid: Cinebench R23 multi-core score of 14372 and Geekbench multi-core of 7579. However, the single-thread scores (Cinebench R23 single-core 2029, Geekbench single-core 1979) are more relevant for Pc Building Simulator, which likely relies on a few primary threads for simulation updates. The 3DMark 2-thread score of 1691 versus the 16-thread score of 5619 suggests that scaling beyond 4 threads is modest — the 4-thread score of 3171 is just 56% of the 16-thread score. This indicates that the game's engine may not effectively utilize more than 4-6 threads.

The CPU's role becomes more evident at 1080p Low, where 298.2 FPS is achieved. This frame rate is likely near the CPU's maximum throughput for this game, as the GPU is far from saturated at these settings. The PassMark single-thread score of 2981 and the 3DMark single-thread score of 868 support the conclusion that the i5-11400F's single-core performance is adequate but not exceptional. Compared to its nearest rivals, the CPU's performance is statistically indistinguishable — all four rivals are within 0.2% of its average benchmark score — meaning that any of these CPUs would produce nearly identical results in this game.

Measured FPS Breakdown

The complete measured FPS data reveals a consistent pattern across all settings and resolutions:

At 1920x1080, the combo delivers 298.2 FPS on Low, 235.9 FPS on Medium, 167.5 FPS on High, and 155.8 FPS on Ultra. The jump from Low to Medium is a 21% reduction, while High to Ultra is only a 7% reduction — indicating that the High and Ultra presets have similar performance costs.

At 2560x1440, the results are 210.8 FPS on Low, 145.1 FPS on Medium, 104 FPS on High, and 101.9 FPS on Ultra. The Medium to High drop is 28%, while High to Ultra is only 2% — a negligible difference that suggests Ultra adds minimal visual enhancements over High at this resolution.

At 3840x2160, the data shows 107.2 FPS on Low, 77 FPS on Medium, 56.1 FPS on High, and 51.8 FPS on Ultra. The High to Ultra drop is just 8%, confirming that the Ultra preset's additional effects have diminishing returns at 4K. The Low to Medium drop at 4K is 28%, similar to the 1440p pattern.

Across all resolutions, the Low preset consistently achieves frame rates more than double those of Ultra: at 1080p, 298.2 vs. 155.8 FPS (1.9x); at 1440p, 210.8 vs. 101.9 FPS (2.1x); at 4K, 107.2 vs. 51.8 FPS (2.1x). This consistent 2x ratio across resolutions indicates that the settings presets scale uniformly regardless of pixel count, pointing to a well-optimized render pipeline that is primarily GPU-bound at higher settings.

The absence of min and max FPS data means that frame time consistency cannot be assessed, but the average FPS values suggest that the combo maintains playable performance at all tested configurations except 4K High and Ultra, where frame rates fall below 60 FPS.
