How This Combo Ranks

The combo's rank of 548 out of 1,769 tested combinations means it sits above roughly 69% of all tested pairings in this simulation game. That is a solid mid-to-upper tier placement, but it is not a top-tier result. The CPU alone holds the 82nd percentile among all processors, while the GPU sits at the 79th percentile among all graphics cards, so neither component is an outlier in performance. The combined result reflects a balanced pairing where the GPU's strengths are somewhat tempered by the CPU's mid-range positioning.

Looking at the CPU's nearest rivals, the Ryzen 5 8400F posts an average benchmark score of 25,064, which is virtually identical to the AMD Ryzen 7 2700X at 25,057. The delta is a mere 0%, meaning these two processors are statistically indistinguishable in average performance. The Ryzen AI 5 PRO 340 scores 25,099 (0.1% higher), and the EPYC 9474F scores 25,103 (0.2% higher), while the Ryzen 5 7500F trails slightly at 24,993 (0.3% lower). This cluster of rivals within a 0.5% band suggests the 8400F's performance is well-characterized and consistent with other mid-range options.

For the GPU, the RX 9070's average benchmark score of 34,780 places it alongside the NVIDIA A2 (34,866, 0.2% higher) and the Quadro GV100 (34,677, 0.3% lower). The AMD Radeon HD 7970 (34,541, 0.7% lower) and PRO W6400 (34,511, 0.8% lower) are slightly behind. These tight deltas indicate the RX 9070 sits in a crowded performance band where small differences separate competitors.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor built on the Zen 4 architecture, codenamed Phoenix, using TSMC's 4 nm process. It has a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The cache layout includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. Memory support is DDR5 over a dual-channel bus with 83.2 GB/s of bandwidth, and the CPU connects via PCIe Gen 4 with 20 lanes.

In Pc Building Simulator, which is not a heavily threaded title, the CPU's single-thread performance is more relevant than its multi-thread capabilities. The 3DMark single-thread score of 951 and Cinebench R23 single-core score of 2,943 indicate strong per-core throughput, which helps maintain high frame rates at lower resolutions. The multi-thread scores, such as Cinebench R23 multi-core at 20,851 and PassMark multi-thread at 24,530, show the 12 threads provide adequate headroom for background tasks and any simulation logic the game may run.

The 8400F's percentile of 82 versus all CPUs confirms it is better than most processors available, but its nearest rivals include older parts like the Ryzen 7 2700X, which matches its average score. This suggests that for a simulation game like Pc Building Simulator, the CPU is not a bottleneck at standard gaming resolutions, but it also does not boost the system beyond what a mid-range processor offers. The 4.70 GHz boost clock helps in lightly-threaded scenarios, while the 16 MB L3 cache is modest by modern standards but sufficient for this game's demands.

GPU Role

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture with the Navi 48 chip, fabricated on TSMC's 4 nm process. It features 3,584 shading units, 224 texture mapping units, and 128 raster operation units, along with 56 ray tracing cores. The GPU operates with a base clock of 1,330 MHz, a game clock of 2,070 MHz, and a boost clock of 2,520 MHz. Memory consists of 16 GB of GDDR6 on a 256-bit bus, delivering 644.6 GB/s of bandwidth.

In Pc Building Simulator, the GPU is the primary driver of frame rates, especially at higher resolutions and settings. The 16 GB VRAM is more than sufficient for a simulation title that does not demand massive texture pools, and the 644.6 GB/s bandwidth ensures data delivery is not a constraint. The pixel rate of 322.6 GPixel/s and texture rate of 564.5 GTexel/s are robust figures that translate to strong fill rates.

The RX 9070's benchmark scores show a well-rounded performer: a 3DMark Steel Nomad DX12 score of 6,290, a Geekbench OpenCL score of 133,741, and a Vulkan score of 165,532. The PassMark G3D score of 25,381 and GPU compute score of 14,737 further confirm its capability. The GPU's 79th percentile among all GPUs means it outperforms most graphics cards, though its nearest rivals include professional and older parts, indicating the performance band is competitive but not advanced.

Resolution Scaling

The measured data reveals a steep performance curve as resolution increases. At 1920x1080 with Low settings, the combo delivers 345.1 FPS average, which drops to 219 FPS at 2560x1440 and further to 116.8 FPS at 3840x2160. This represents a 66% reduction from 1080p to 4K at Low settings, indicating the GPU is the primary scaling factor.

For High settings, the progression is 174 FPS at 1080p, 109.5 FPS at 1440p, and 57 FPS at 4K. The drop from 1440p to 4K is particularly steep, with a 48% reduction. At Ultra settings, the numbers are 167.4 FPS at 1080p, 103 FPS at 1440p, and 56.6 FPS at 4K. The consistency of the 4K results around 57 FPS across High, Medium, and Ultra settings suggests that at 4K, the GPU is hitting a performance ceiling where additional settings changes have minimal impact.

The scaling pattern indicates that at 1080p, the CPU has more influence, as evidenced by the large differences between Low (345.1 FPS) and Ultra (167.4 FPS) settings. At 4K, the GPU becomes the dominant limiting factor, with frame rates compressing into a narrow band from 56.6 to 116.8 FPS across all settings. This transition point appears to occur somewhere between 1440p and 4K, where the GPU's rendering load outweighs the CPU's contribution.

Settings Recommendations

For a balanced experience, High settings at 2560x1440 provide 109.5 FPS average, which is well above the 60 FPS threshold for smooth gameplay while maintaining visual quality. This represents a good compromise between the 152.3 FPS at Medium and the 103 FPS at Ultra, with the High preset offering only 6% less performance than Ultra but with reduced visual demands.

At 1920x1080, all settings are playable, with even Ultra delivering 167.4 FPS average. The data suggests that 1080p Ultra is the best experience for high-refresh monitors, as it provides over 160 FPS while keeping all visual features enabled. For 4K displays, the situation is more constrained: High settings yield 57 FPS, which is borderline for smooth play, while Medium delivers 82.1 FPS and Low reaches 116.8 FPS. Given that Ultra at 4K only achieves 56.6 FPS, dropping to Medium or High is advisable for 4K play.

The most efficient settings choice appears to be High at 1440p, which offers 109.5 FPS and uses less GPU headroom than Ultra, potentially allowing for more consistent frame times. For users prioritizing frame rate over visual fidelity, Medium at 1440p at 152.3 FPS is a strong option, as it nearly matches High at 1080p while offering higher resolution.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values are: Low at 345.1, Medium at 242.6, High at 174, and Ultra at 167.4. The gap between Low and Medium is 102.5 FPS, while the gap between High and Ultra is only 6.6 FPS, suggesting diminishing returns at the highest settings.

At 2560x1440, the results are: Low at 219, Medium at 152.3, High at 109.5, and Ultra at 103. The transition from Medium to High represents a 42.8 FPS drop, which is the largest step-down in this resolution. Both High and Ultra remain above 100 FPS, making 1440p a viable option for high-refresh gaming.

At 3840x2160, the data shows: Low at 116.8, Medium at 82.1, High at 57, and Ultra at 56.6. The difference between High and Ultra is negligible at just 0.4 FPS, indicating that the Ultra preset adds no meaningful performance cost but also no additional headroom. The drop from Medium to High is 25.1 FPS, which is substantial and pushes the experience below 60 FPS.

Across all resolutions, the Low settings consistently deliver roughly double the frame rate of Ultra settings. At 1080p, Low is 2.06 times faster than Ultra; at 1440p, it is 2.13 times faster; and at 4K, it is 2.06 times faster. This consistent ratio suggests the settings scaling is uniform across resolutions, with the GPU handling the same relative workload increase. The absolute frame rates, however, show that 4K gaming with this combo requires accepting either lower settings or frame rates near 60 FPS, while 1080p and 1440p provide ample headroom for any settings choice.
