Pc Building Simulator

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 5090 is a top-tier combination for Pc Building Simulator, ranking 28th out of 1,769 tested combos. Measured frame rates are exceptionally high across all resolutions and settings, with the combo delivering over 85 FPS even at 4K Ultra. The data shows that the RTX 5090’s massive memory bandwidth and the Ryzen 5 8400F’s strong single-thread performance combine to produce a system that is rarely the bottleneck in this simulation title.

Settings Recommendations

The measured FPS rows reveal a clear sweet spot: the Medium preset offers the best balance of visual quality and frame rate. At 4K, Medium delivers 128.5 FPS, which is 43% higher than High’s 89.9 FPS and 50% higher than Ultra’s 85.9 FPS. The jump from High to Medium is substantial, while the drop from High to Ultra is only 4.5% (89.9 to 85.9). At 1440p, Medium hits 243.8 FPS versus 168.9 on High and 159.7 on Ultra—a 44% advantage over High. At 1080p, Medium reaches 329.3 FPS, compared to 271.9 on High and 258 on Ultra. In every resolution, Medium provides a large FPS boost over High while still being a higher preset than Low. For players seeking maximum visual fidelity, High is preferable to Ultra because it consistently outperforms Ultra by 4–6 FPS across resolutions. However, the data strongly supports Medium as the best experience per measured row, especially for high-refresh-rate displays.

GPU Role

The RTX 5090 is a dominant force in this game. Its 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, and its boost clock reaches 2407 MHz. These specifications translate into headroom that the game rarely stresses. At 4K Ultra, the GPU still manages 85.9 FPS, and at 1080p Low it hits 374.3 FPS. The GPU’s benchmark percentile is 94, with an average score of 84,306, placing it among the fastest cards tested. Its nearest rival, the RTX 5090 D, scores 84,241 (0.1% higher), while the RTX 5050 Mobile scores 84,171 (0.2% higher)—all within a 1.6% band. The GPU’s 104.8 TFLOPS FP32 compute and 1,636.8 GTexel/s texture rate are far beyond what Pc Building Simulator requires. The data indicates that the GPU is not the limiting factor at 1080p or 1440p; even at 4K, the frame rates remain high, suggesting the game is not particularly GPU-intensive. The 32 GB VRAM is more than sufficient, and the high memory bandwidth ensures no bandwidth-related stutters.

How This Combo Ranks

The combo rank of 28 out of 1,769 places this pairing in the top 1.6% of all tested configurations for Pc Building Simulator. This is consistent with the individual component percentiles: the CPU sits at the 82nd percentile (average benchmark score 25,064), and the GPU at the 94th percentile (average score 84,306). The CPU’s nearest rivals—the Ryzen 7 2700X (25,057, 0% delta), Ryzen AI 5 PRO 340 (25,099, -0.1%), EPYC 9474F (25,103, -0.2%), and Ryzen 5 7500F (24,993, 0.3%)—show that the 8400F is essentially on par with those chips. The GPU’s nearest rivals are similarly close, with the RTX 5090 D (84,241, 0.1%), RTX 5050 Mobile (84,171, 0.2%), Radeon PRO W6600 (83,209, 1.3%), and CMP 40HX (85,637, -1.6%). The high combo rank reflects that this CPU-GPU pairing is well matched for this game, with no obvious bottleneck.

CPU Role

The Ryzen 5 8400F is a 6-core, 12-thread processor based on Zen 4 (Phoenix) architecture, built on a 4 nm process. Its base clock is 4.20 GHz and boost clock reaches 4.70 GHz, with a TDP of 65 W. The CPU’s single-thread performance is strong: it scores 951 in 3DMark single-thread, 2,943 in Cinebench R23 single-core, and 3,684 in Passmark single-thread. Multi-thread scores are also respectable—Cinebench R23 multi-core hits 20,851, and Passmark multi-thread reaches 24,530. The CPU’s average benchmark score is 25,064, placing it at the 82nd percentile. Its nearest rival, the Ryzen 7 2700X, scores 25,057 (0% delta), indicating the 8400F is effectively tied with that older chip. In Pc Building Simulator, the CPU’s role is to feed the GPU with enough data. The measured FPS at 1080p Low (374.3) and 1440p Low (317.1) shows that the CPU is not a bottleneck even at low settings, where the GPU is less stressed. The high single-thread score and 4.70 GHz boost clock ensure that the game’s simulation logic runs smoothly. The CPU’s launch MSRP is $170, but its performance in this game is far above what that price suggests.

Resolution Scaling

The FPS drop from 1080p to 4K reveals the limiting component. At High settings, the average FPS falls from 271.9 at 1080p to 168.9 at 1440p (a 38% drop) and then to 89.9 at 4K (a 47% drop from 1440p). The larger drop from 1440p to 4K indicates that the GPU becomes the primary limiter at higher resolutions. At Low settings, the drop from 1080p to 1440p is only 15% (374.3 to 317.1), but the drop from 1440p to 4K is 44% (317.1 to 176.4). This pattern—smaller drops at lower resolutions and larger drops at 4K—confirms that the GPU is the bottleneck at 4K, while the CPU and memory system are sufficient to keep frame rates high at 1080p and 1440p. At Medium settings, the drop from 1080p to 1440p is 26% (329.3 to 243.8) and from 1440p to 4K is 47% (243.8 to 128.5). The consistent 44–47% drop from 1440p to 4K across all presets shows that the RTX 5090’s performance scales predictably with resolution, and the CPU does not introduce a significant bottleneck until the GPU is fully loaded. The data suggests that for 4K gaming, the GPU is the limiting factor, while at 1080p and 1440p, the combo has ample headroom.
