Pc Building Simulator

Pc Building Simulator with an AMD Ryzen 5 8400F and AMD Radeon RX 6700 XT presents a distinct scaling profile; the data indicates that the CPU is rarely the limiting factor, allowing the GPU to dictate performance across the resolution spectrum. The measured FPS progression suggests a system that is heavily balanced toward GPU throughput, with the CPU's strong single-thread performance ensuring it stays out of the way even at high frame rates.

Resolution Scaling

The performance drop from 1080p to 4K is substantial, a typical indicator of a GPU-bound scenario. At 1080p with Ultra settings, the combo produces an average of 128.8 FPS. Moving to 1440p reduces that to 81.3 FPS, a decline of approximately 37%. At 4K, the average falls to 43.6 FPS, which is a 66% reduction from the 1080p result. This steep curve illustrates that the rendering load is scaling directly with pixel count, placing the burden squarely on the Radeon RX 6700 XT.

The scaling from 1440p to 4K shows a similar pattern across all settings. For instance, at High settings, the transition from 1440p (86.5 FPS) to 4K (45.2 FPS) halves the frame rate. This consistent halving at higher resolutions confirms that the GPU's fillrate and memory bandwidth are the primary determinants of performance, not the CPU's processing capabilities. The Ryzen 5 8400F, with its high boost clock, is capable of feeding the GPU enough data to saturate it, but the GPU's raw throughput becomes the bottleneck as resolution increases.

The gap between Low and Ultra settings also widens with resolution. At 1080p, the difference between Low (268.1 FPS) and Ultra (128.8 FPS) is 139.3 FPS. At 4K, that difference shrinks to 45.8 FPS (89.4 vs 43.6). This compression indicates that at lower resolutions, the CPU and GPU are working in a more balanced state, but at 4K, the GPU is so saturated that even reducing the graphical load cannot fully compensate for the pixel throughput demands. The data shows a classic GPU-limited scaling curve, with the CPU's role diminishing as resolution climbs.

GPU Role

The AMD Radeon RX 6700 XT is the clear performance driver in this configuration. Its 12 GB of GDDR6 memory on a 192-bit bus provides a bandwidth of 384.0 GB/s, which is ample for the textures and assets in Pc Building Simulator. The GPU's boost clock of 2581 MHz and game clock of 2424 MHz are relatively high, allowing for robust compute throughput that directly translates into the high frame rates seen at 1080p and 1440p. The card's architecture, RDNA 2.0, with 2560 shading units and 160 TMUs, provides the raw processing power needed to handle the game's simulation and rendering tasks.

The GPU's benchmark scores corroborate its performance tier. It holds a percentile rank of 77 among all GPUs, with a PassMark G3D score of 19786. Its nearest rival, the AMD Radeon RX 6800, has an average score of 33493, which is 0.7% higher, indicating the 6700 XT is just a step below a higher-tier card. Conversely, the NVIDIA RTX A5000 scores 1.3% lower, placing the 6700 XT in a competitive mid-to-high range. This positioning is reflected in the measured FPS, where the GPU can push beyond 200 FPS at 1080p on Low settings, but struggles to maintain playable frame rates at 4K Ultra, where the 43.6 FPS average is close to the edge of smooth gameplay.

The VRAM capacity is a notable asset. While not heavily taxed by this simulation title at the tested settings, having 12 GB ensures that the GPU does not run into memory allocation issues, which could cause stutters or texture pop-in. The 384.0 GB/s bandwidth provides the necessary data transfer speed to keep the shaders and TMUs fed, particularly at higher resolutions where memory pressure increases. The GPU's performance is the primary reason this combo ranks where it does, as it provides the majority of the computational muscle.

How This Combo Ranks

In the database of tested combinations, this pairing of the Ryzen 5 8400F and RX 6700 XT achieves a rank of 955 out of 1769 combos for Pc Building Simulator. This places it in the 54th percentile of all tested systems, meaning it outperforms slightly more than half of the configurations in this specific game. This mid-pack ranking is consistent with the hardware's profile; the CPU is a solid modern part, and the GPU is a capable previous-generation card, but they do not represent a top-tier pairing for this title.

The ranking suggests that while the system is well-balanced, it is not optimized for maximum performance in this simulation. The CPU's nearest rivals, such as the AMD Ryzen 7 2700X, have nearly identical average benchmark scores (25057 vs 25064, a 0% delta), indicating the 8400F is not providing a unique advantage. Similarly, the GPU's closest competitor, the RX 6800, is only 0.7% faster on average. This means the combo's rank is not due to an exceptional part, but rather a reasonable pairing of mid-range components.

The rank of 955 also implies that many other combos, likely with higher-tier GPUs or newer CPUs, can deliver better frame rates. However, the measured data shows this system is far from a slouch. It achieves over 100 FPS at 1080p on High settings, which is a comfortable experience for most users. The ranking reflects a system that is more than capable for 1080p and 1440p gaming, but it may be outperformed by combos with more powerful graphics cards in this specific benchmark suite.

Measured FPS Breakdown

At 1920x1080, the processor and GPU combination demonstrates its peak performance. With Low settings, the average FPS is 268.1, a figure that underscores the CPU's ability to handle high frame rates without bottlenecking. Medium settings reduce this to 191.8 FPS, while High settings yield 134.7 FPS. Ultra settings bring the average down to 128.8 FPS, still a highly playable result. The small delta between High and Ultra (5.9 FPS) suggests that the Ultra preset adds graphical effects that are not particularly taxing on the GPU at this resolution.

Moving to 2560x1440, the frame rates remain strong but show a clear dependency on the GPU. Low settings produce 169.7 FPS, which is a 37% reduction from the 1080p Low result, highlighting the increased pixel workload. Medium settings deliver 122.6 FPS, and High settings drop to 86.5 FPS. Ultra settings at 1440p give an average of 81.3 FPS, which is still smooth for a simulation title. The scaling factor from 1080p to 1440p is roughly 0.63 across all settings, indicating a consistent GPU workload increase.

At 3840x2160, the GPU becomes the absolute bottleneck. Low settings produce 89.4 FPS, which is respectable, but High settings fall to 45.2 FPS. Medium settings yield 63.4 FPS, and Ultra settings drop to 43.6 FPS. The difference between High and Ultra at 4K is only 1.6 FPS, demonstrating that the GPU is completely saturated and additional graphical fidelity has minimal impact on performance. The transition from 1440p High (86.5 FPS) to 4K High (45.2 FPS) represents a 48% reduction in frame rate, underscoring the challenge of driving 4K with this graphics card. The data shows that 1440p is the sweet spot for this combo, balancing visual quality with high frame rates, while 4K is only viable on lower settings.

CPU Role

The AMD Ryzen 5 8400F, with its 6 cores and 12 threads, provides a solid foundation for this game. Its base clock of 4.20 GHz and boost clock of 4.70 GHz, combined with a 16 MB shared L3 cache, ensure that the CPU can handle the game's logic and simulation threads without becoming a bottleneck. The benchmark data supports this, with a Cinebench R23 multi-core score of 20851 and a single-core score of 2943, indicating robust performance in both heavily threaded and single-threaded workloads.

The CPU's nearest rivals, such as the AMD Ryzen 5 7500F, have an average score of 24993, which is only 0.3% lower than the 8400F's 25064. This suggests that the 8400F is performing as expected for its class. The high single-thread performance is particularly important for Pc Building Simulator, which likely has a primary game thread that benefits from the 4.70 GHz boost. The 3DMark single-thread score of 951, while not directly comparable to gaming, reinforces the CPU's ability to execute instructions quickly.

In this game, the CPU's role is to feed the GPU. The data shows that at 1080p Low, the system achieves 268.1 FPS, which is a high enough frame rate that a weaker CPU would likely become a limiting factor. However, the 8400F's 12 threads and high clock speeds prevent this, allowing the GPU to reach its maximum output. As resolution increases, the CPU's workload remains constant while the GPU's workload increases, so the CPU's importance diminishes. The 65W TDP and 4 nm process node also indicate an efficient part that does not generate excessive heat, but these factors have no direct impact on the game's measured FPS. Overall, the CPU provides ample headroom, ensuring the GPU is the sole determinant of the frame rates seen in the resolution scaling analysis.
