Pc Building Simulator

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 5070 combination delivers a remarkably consistent experience in Pc Building Simulator, with the data showing that the GPU becomes the primary constraint only at 4K, while lower resolutions reveal a CPU-bound scenario. This pairing ranks in the top 20% of all tested combos in this title, placing it at rank 345 out of 1769.

Resolution Scaling

The frame rate scaling from 1080p to 4K clearly illustrates where the bottleneck shifts. At 1080p with Low settings, the combo produces 371.2 FPS, but at 4K Low, it drops to 132.6 FPS, a substantial reduction of 238.6 FPS. This indicates that at 1080p, the CPU is the limiting factor, as the GPU has ample headroom to render frames far beyond what the processor can feed it.

Moving to 1440p, the scaling shows a more balanced workload. At Low settings, the system achieves 251.7 FPS, which is 119.5 FPS lower than the 1080p result. This suggests that while the GPU is beginning to take on more work, the CPU still plays a significant role in determining the final output.

The 4K results tell a different story. At Ultra settings, the combo delivers 64.1 FPS, which is only 0.6 FPS higher than the High preset result of 63.5 FPS. This near-identical performance between High and Ultra at 4K, alongside the jump from 92.1 FPS at Medium to 132.6 FPS at Low, indicates that the GPU is now the definitive limiting component. The data shows that the RTX 5070's rendering capacity is fully saturated at this resolution, with settings having a pronounced impact on the final frame count.

GPU Role

The RTX 5070's memory configuration plays a crucial role in these results. With 12 GB of GDDR7 memory on a 192-bit bus, the card provides 672.0 GB/s of bandwidth. In Pc Building Simulator, this bandwidth appears sufficient at all tested settings, as the frame rate differences between presets at 4K are substantial, ranging from 132.6 FPS at Low to 64.1 FPS at Ultra.

The GPU's clock speeds, with a base of 2325 MHz and a boost of 2512 MHz, contribute to its ability to maintain high frame rates at lower resolutions. The data shows that at 1440p High, the combo reaches 123.9 FPS, which is more than double the 4K High result of 63.5 FPS. This performance gap highlights that the GPU's raw compute power, measured at 30.87 TFLOPS FP32, is more than adequate for this simulation title at mainstream resolutions.

The 83rd percentile ranking against all GPUs, based on an average benchmark score of 41687, positions this card as a high-end performer. When compared to the NVIDIA GeForce RTX 3090, which has an average score of 41441 and a deltaPct of 0.6, the RTX 5070 shows a slight edge in synthetic benchmarks, though the in-game results suggest both would perform similarly at 4K.

How This Combo Ranks

The combination of the Ryzen 5 8400F and RTX 5070 achieves a rank of 345 out of 1769 tested combos in Pc Building Simulator. This places it in the top 19.5% of all combinations, indicating strong overall performance for this title.

The CPU's contribution to this ranking is significant. The Ryzen 5 8400F scores in the 82nd percentile against all CPUs, with an average benchmark score of 25064. Its nearest rival, the AMD Ryzen 7 2700X, has an average score of 25057, representing a 0% deltaPct, meaning the two processors perform nearly identically in synthetic tests. However, the 8400F's newer Zen 4 architecture, built on a 4 nm process, provides efficiency benefits that the older 2700X lacks.

The GPU's 83rd percentile ranking, combined with the CPU's 82nd percentile, creates a balanced pairing where neither component severely bottlenecks the other at most resolutions. The data supports this: at 1440p Ultra, the combo delivers 120.8 FPS, which is a playable and smooth experience for a simulation game.

FAQ

Q: Is the RTX 5070 strong enough for 4K gaming in Pc Building Simulator?

A: Yes, the measured data shows 63.5 FPS at 4K High and 64.1 FPS at 4K Ultra, both of which are playable frame rates for this simulation genre.

Q: How does the Ryzen 5 8400F compare to its closest rival?

A: The Ryzen 5 8400F has an average benchmark score of 25064, while the AMD Ryzen 7 2700X scores 25057, resulting in a 0% deltaPct, indicating nearly identical synthetic performance.

Q: What is the biggest frame rate jump between settings?

A: At 1080p, moving from High (198.3 FPS) to Low (371.2 FPS) produces a 172.9 FPS increase, the largest single-setting jump in the measured data.

Q: Does the CPU bottleneck the GPU at 1080p?

A: Yes, the data strongly suggests this. At 1080p Low, the combo achieves 371.2 FPS, but at 1440p Low, it drops to 251.7 FPS, indicating the CPU cannot feed the GPU enough frames at the lower resolution.

Q: What is the difference between High and Ultra settings at 1440p?

A: The measured results show 123.9 FPS at High and 120.8 FPS at Ultra, a difference of only 3.1 FPS, suggesting Ultra provides a visual upgrade with minimal performance cost.

Q: How does this combo rank among all tested combinations?

A: It ranks 345 out of 1769 total combos, placing it in the top 20% for Pc Building Simulator performance.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce 371.2 FPS, Medium achieves 283 FPS, High reaches 198.3 FPS, and Ultra drops to 192 FPS. The scaling from Ultra to Low represents a 179.2 FPS improvement, showing that the CPU is the primary limiter here.

Moving to 2560x1440, the results show a more GPU-influenced pattern. Low settings yield 251.7 FPS, Medium drops to 176.8 FPS, High settles at 123.9 FPS, and Ultra provides 120.8 FPS. The difference between High and Ultra narrows to just 3.1 FPS at this resolution.

At 3840x2160, the GPU becomes the clear bottleneck. Low settings deliver 132.6 FPS, Medium drops to 92.1 FPS, High reaches 63.5 FPS, and Ultra produces 64.1 FPS. Interestingly, Ultra is 0.6 FPS higher than High at 4K, which could indicate minor measurement variance or that the Ultra preset's additional effects are not fully taxing the GPU.

CPU Role

The Ryzen 5 8400F's six cores and twelve threads, based on the Zen 4 Phoenix architecture, provide solid single-threaded performance that is crucial for simulation games. Its boost clock of 4.70 GHz, combined with a base clock of 4.20 GHz, delivers strong per-core performance. The 3dmark single-thread score of 951 and the cinebench_r23_singlecore score of 2943 both indicate robust single-core capability.

The 16 MB of shared L3 cache and 1 MB of L2 cache per core help reduce memory latency, which is beneficial for the logic-heavy calculations typical of simulation titles. The 83.2 GB/s memory bandwidth, paired with DDR5 support, provides ample data throughput for the CPU to feed the GPU.

At 1080p, the CPU's performance ceiling is evident. The fact that the combo can reach 371.2 FPS at Low settings but only 192 FPS at Ultra shows that the graphics workload, not the CPU, is the differentiator at these settings. The 179.2 FPS gap between Low and Ultra at 1080p is entirely attributable to GPU load, while the CPU maintains its output.

Settings Recommendations

For 4K displays, the data shows that High and Ultra presets both deliver around 63-64 FPS, making either a viable choice. The 0.6 FPS difference between them suggests that Ultra can be selected without meaningful performance loss, providing the best visual quality for a smooth 60 FPS experience.

At 1440p, High settings at 123.9 FPS offer the best balance, with Ultra providing 120.8 FPS for only a 3.1 FPS reduction. Both are excellent for high-refresh-rate monitors, but Medium at 176.8 FPS is the recommended choice for 144Hz displays where maximum smoothness is prioritized.

For 1080p users, the CPU becomes the limiting factor above 192 FPS. Ultra at 192 FPS and High at 198.3 FPS are nearly identical, making Ultra the clear recommendation for visual quality. Medium at 283 FPS and Low at 371.2 FPS are only useful for competitive play or extremely high refresh rate monitors, as the visual downgrade is significant. The measured data indicates that the Ultra preset at 1080p provides the best overall experience.
