# Pc Building Simulator with AMD Ryzen 5 8400F + NVIDIA GeForce RTX 5090 D

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 5090 D produces a fascinating benchmark profile in Pc Building Simulator, where the simulation's workload characteristics become clearly visible across resolution and settings scaling. The measured data shows a system capable of extreme frame rates at lower resolutions, but with a distinct pattern of diminishing returns as pixel count rises, suggesting a complex interplay between the 6-core/12-thread Zen 4 processor and the massive Blackwell GPU. At 1080p Low, the combo delivers 372 FPS average, yet at 4K Ultra that figure drops to just 89 FPS — a 76% reduction that reveals where the bottleneck shifts as the rendering load intensifies.

Resolution Scaling

The resolution scaling pattern in Pc Building Simulator tells a compelling story about system balance. Moving from 1920x1080 to 2560x1440 at High settings, the average FPS drops from 284 to 179 — a 37% reduction. The step from 1440p to 3840x2160 at High is even more punishing, falling from 179 to 94 FPS, another 47% decline. This compounding effect means that at 4K High, the system delivers less than one-third of its 1080p High performance.

At Low settings, the scaling story shifts. The 1080p Low result of 372 FPS drops to 319 FPS at 1440p (a 14% reduction) and then to 187 FPS at 4K (a 41% reduction from 1440p). The smaller penalty between 1080p and 1440p at Low settings suggests that at these lower quality presets, the CPU is more capable of feeding frames, and the GPU has enough headroom that the resolution increase doesn't immediately overwhelm it. However, the large drop when moving to 4K Low indicates that even at minimal settings, the pixel throughput demands of 4K begin to strain the rendering pipeline.

The Medium settings data includes min/max FPS values, providing insight into frame time consistency. At 4K Medium, the average is 133 FPS with a measured range of 113 to 153 FPS — a 40 FPS spread. At 1440p Medium, the average rises to 254 FPS with a range of 216 to 292 FPS, a 76 FPS spread. At 1080p Medium, the average reaches 327 FPS with a range of 278 to 376 FPS, a 98 FPS spread. This widening range at higher frame rates is typical of CPU-bound scenarios where thread scheduling and simulation tick variability create larger absolute frame time fluctuations.

The Ultra settings show the most dramatic resolution sensitivity. The 270 FPS at 1080p Ultra falls to 171 FPS at 1440p Ultra (a 37% drop) and then to 89 FPS at 4K Ultra (a 48% drop from 1440p). This near-linear degradation pattern across resolutions at Ultra settings indicates that the Ultra preset's additional rendering features scale consistently with pixel count, unlike the Low preset where the 1440p step shows relatively mild impact.

CPU Role

The AMD Ryzen 5 8400F brings 6 cores and 12 threads to this pairing, operating with a base clock of 4.20 GHz and a boost clock of 4.70 GHz. This Zen 4 architecture processor, built on TSMC's 4 nm process, features 16 MB of shared L3 cache and 1 MB L2 per core. The CPU's benchmark scores place it in the 77th percentile among all CPUs, with an average benchmark score of 25,005.

Passmark results show a multithread score of 24,389 and a single-thread score of 3,685, with the physics test scoring 1,332.

In the context of Pc Building Simulator, the CPU's 6-core/12-thread configuration appears to be a significant factor in the high frame rates observed at 1080p. The simulation genre typically involves substantial CPU-side logic for tracking component states, thermal calculations, and system interactions. The 8400F's boost clock of 4.70 GHz provides strong single-thread performance, which is often critical for simulation update loops.

Comparing to nearest rivals, the Ryzen 5 8400F sits within a tight performance band. The AMD Ryzen 5 7500F scores 24,964 (0.2% lower), the Intel Core i7-11850H scores 24,935 (0.3% lower), and the Intel Core i7-13620H scores 24,911 (0.4% lower). The AMD EPYC 9474F scores 25,103 (0.4% higher). This clustering suggests that the 8400F's computational throughput is well-matched to its peers, meaning any performance differences in-game are more likely attributable to architectural characteristics than raw compute headroom.

Settings Recommendations

The measured FPS data provides clear guidance for optimizing the visual experience versus performance trade-off in Pc Building Simulator. At 4K, the Ultra preset delivers 89 FPS average, which is playable but leaves little headroom for demanding scenes. The High preset at 4K increases performance to 94 FPS, a modest 5 FPS gain that may not justify dropping from Ultra. However, the Medium preset at 4K delivers 133 FPS, a 44 FPS improvement over Ultra while presumably maintaining reasonable visual quality.

At 1440p, the picture changes. The Ultra preset delivers 171 FPS, which exceeds typical high-refresh-rate monitor capabilities. The High preset provides 179 FPS (an 8 FPS gain), while Medium delivers 254 FPS (an 83 FPS gain over Ultra). For users with 144 Hz or 165 Hz displays, the Ultra preset at 1440p is already sufficient, making the lower presets unnecessary unless maximum frame rates are desired.

The 1080p results show that even the Ultra preset delivers 270 FPS, which is beyond what most displays can show. The Low preset at 372 FPS represents the absolute maximum performance this combo can achieve, but the 102 FPS difference between Low and Ultra (372 vs 270) comes at a significant visual quality cost. For competitive play or maximum responsiveness, the Low preset's 372 FPS could be beneficial, but for general use, the Ultra preset at 270 FPS provides an excellent balance.

The Medium settings at each resolution provide the best documented frame time data, with min/max values captured. At 4K Medium, the 113-153 FPS range suggests consistent performance. At 1440p Medium, the 216-292 FPS range shows wider variance. At 1080p Medium, the 278-376 FPS range demonstrates the largest absolute spread, indicating that at these high frame rates, the CPU's role in frame pacing becomes more apparent. For users prioritizing consistent frame delivery, the Medium preset at 1440p (254 FPS average) appears to offer the best combination of high performance and measured stability.

GPU Role

The NVIDIA GeForce RTX 5090 D is a massive GPU based on the GB202 chip, built on TSMC's 5 nm process with 92,200 million transistors on a 750 mm² die. The GPU operates at a base clock of 2017 MHz with a boost clock of 2407 MHz, and features 32 GB of GDDR7 memory on a 512-bit bus, providing 1.79 TB/s of memory bandwidth. The memory runs at 1750 MHz with 28 Gbps effective speed.

The GPU's compute specifications are substantial: 21,760 shading units, 680 texture mapping units, 176 ROPs, 170 ray tracing cores, and 680 tensor cores. The pixel rate is rated at 423.6 GPixel/s, texture rate at 1,636.8 GTexel/s, and FP32 performance at 104.8 TFLOPS. The card carries a TDP of 575 W and requires a 950 W suggested PSU, with a dual-slot design and 1x 16-pin power connector.

In Pc Building Simulator, the GPU's role appears to become increasingly dominant at higher resolutions. The 4K performance gap between Low (187 FPS) and Ultra (89 FPS) suggests that the Ultra preset introduces rendering features that heavily tax the GPU's pixel processing capabilities. The 32 GB of VRAM is unlikely to be a limiting factor in this simulation game, as even the most demanding texture loads typically fall well below this capacity.

The GPU's benchmark results show strong performance across different APIs: 3DMark Steel Nomad DX12 scores 14,326, Geekbench OpenCL scores 310,674, and Geekbench Vulkan scores 376,915. The Passmark results show DirectX 11 scoring 371, DirectX 12 scoring 219, DirectX 10 scoring 231, and DirectX 9 scoring 434. The G3D score of 44,065 and compute score of 28,396 further characterize the GPU's capabilities.

The GPU's 92nd percentile ranking among all GPUs, combined with its average benchmark score of 77,712, confirms its position as a high-end part. However, the nearest rival data shows that the RTX 5090 D's raw benchmark scores are surprisingly close to mobile and datacenter parts, with the AMD Radeon RX 6850M XT scoring 1.6% higher. This suggests that in synthetic benchmarks, the 5090 D's performance is competitive but not overwhelmingly dominant, though its in-game performance in Pc Building Simulator benefits from the specific optimization of this title.

The GPU's memory bandwidth of 1.79 TB/s is likely a key factor in the 4K performance scaling. As resolution increases, the demand for texture bandwidth and framebuffer throughput grows, and the 512-bit bus with GDDR7 memory provides substantial headroom. The 2407 MHz boost clock ensures that the GPU can maintain high utilization even when the simulation's CPU-side logic is processing component interactions and system state updates.
