Pc Building Simulator

# CPU Role

The AMD Ryzen 5 8400F brings a 6-core, 12-thread configuration based on the Zen 4 (Phoenix) architecture, running on the AM5 socket. This is a desktop-class processor with a base clock of 4.20 GHz and a boost clock of 4.70 GHz, which places it firmly in the mid-range tier for gaming workloads. The CPU's cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and a shared 16 MB L3 cache. Its 65W TDP suggests it is designed for efficiency, while the unlocked multiplier indicates headroom for overclocking. The processor supports DDR5 memory in a dual-channel configuration with a bandwidth of 83.2 GB/s, which is relevant for a simulation title that may rely on memory throughput.

For Pc Building Simulator, the benchmark results demonstrate a strong relationship between core utilization and performance. Looking at synthetic benchmarks, the CPU scores 6,091 in 3DMark 16-thread tests and 6,165 in max-thread tests, showing that the processor scales well when all 12 threads are engaged. The single-thread score of 951 and the 2-thread score of 1,874 indicate that lightly threaded tasks are handled competently, which matters for a game that likely has a primary simulation thread. The Cinebench R23 multi-core score of 20,851 and single-core score of 2,943 further reinforce that this is a balanced processor for both multi-threaded and single-threaded workloads.

Relative to its nearest rivals, the Ryzen 5 8400F sits within a tight competitive band. It is 0.2% ahead of the AMD Ryzen 5 7500F, 0.3% ahead of the Intel Core i7-11850H, and 0.4% ahead of the Intel Core i7-13620H in average benchmark score, while trailing the AMD EPYC 9474F by 0.4%. These deltas are negligible, meaning the CPU's performance class is well-established among its peers. The 77th percentile ranking against all CPUs, with an average benchmark score of 25,005, indicates that this processor outperforms roughly three-quarters of the tested CPU pool. For a simulation game like Pc Building Simulator, where frame pacing and consistent logic updates matter, this level of single-thread and multi-thread performance is sufficient to avoid becoming the primary bottleneck at most settings.

The data implies that the CPU's role in this game is to maintain a high baseline for physics and simulation logic. The 3DMark 8-thread score of 5,275 suggests that even when the game taps into multiple cores—perhaps for managing multiple PC build scenarios or background calculations—the processor can keep up. The PassMark multi-thread score of 24,389 and single-thread score of 3,685 align with the expectation that this CPU will not hold back the GPU in most in-game scenarios, especially at lower resolutions where the GPU has more headroom.

GPU Role

The AMD Radeon RX 7700 is built on the RDNA 3.0 architecture with the Navi 32 chip, fabricated on a 5nm process by TSMC. It features 16 GB of GDDR6 memory on a 256-bit bus, yielding a bandwidth of 624.1 GB/s. The GPU's clock speeds include a base of 1900 MHz, a boost of 2459 MHz, and a game clock of 2041 MHz, with memory running at 2438 MHz (19.5 Gbps effective). The shader configuration includes 2,560 shading units, 160 TMUs, and 96 ROPs, along with 40 ray tracing cores. The pixel rate is 236.1 GPixel/s and the texture rate is 393.4 GTexel/s, with FP32 performance rated at 25.18 TFLOPS.

For Pc Building Simulator, the GPU's role is critical for rendering the visual elements of the simulation, including the 3D models of components, case interiors, and lighting effects. The 16 GB VRAM is notably generous for a game of this genre, ensuring that texture data and complex scenes won't exceed memory capacity even at 4K resolution. The GPU's 58th percentile ranking against all GPUs, with an average benchmark score of 15,852, places it in the mid-to-upper tier of graphics hardware. However, its nearest rivals tell an interesting story: it is 0.1% behind the AMD Radeon R9 370X, 1% behind the AMD Radeon RX 9060, and 1.7% behind the NVIDIA GeForce RTX 3060 Ti, while being 1.1% ahead of the AMD Radeon Pro W5500. These small deltas suggest that while the RX 7700 is competitive, it is not a class leader in raw synthetic benchmarks.

The GPU's DirectX 12 Ultimate support (12_2), Vulkan 1.4, and OpenGL 4.6 APIs position it well for modern game engines. The PassMark G3D score of 20,974 and DirectX 12 score of 96 indicate strong DirectX 12 performance, which is relevant if Pc Building Simulator leverages modern rendering paths. The 3DMark Steel Nomad DX12 score of 2,865 provides a baseline for higher-end graphical loads. In the context of this game, the GPU appears to be the more significant performance determinant, as the measured FPS varies substantially with settings changes, suggesting that visual effects and resolution scaling tax the GPU more than the CPU.

Settings Recommendations

The measured FPS data provides clear guidance on the optimal settings for this combo. At 1080p, the Medium preset delivers an average of 200 FPS with a minimum of 170 FPS and a maximum of 230 FPS, which is an excellent balance of smoothness and visual fidelity. The High preset at 1080p yields 141 FPS, while Ultra drops to 134 FPS—both are playable, but Medium offers a substantial margin above 60 FPS for any potential frame drops. The Low preset at 1080p reaches 282 FPS, but this sacrifices too much visual quality for a simulation game where reading component details matters.

At 1440p, the Medium preset again stands out with an average of 126 FPS, a minimum of 107 FPS, and a maximum of 145 FPS. This resolution provides a sharper image while maintaining high frame rates. The High preset at 1440p averages 89 FPS, which is still smooth, but the Medium preset's 126 FPS average gives more headroom. The Ultra preset at 1440p averages 85 FPS, which is acceptable but begins to approach the limit of what some users might consider high refresh rate territory.

At 4K, the Medium preset is the only viable option for high-refresh-rate play, averaging 66 FPS with a minimum of 56 FPS and a maximum of 76 FPS. This is on the edge of the 60 FPS threshold, meaning there could be occasional dips below that mark. The High preset at 4K averages 47 FPS, and Ultra averages 44 FPS, both of which are below the ideal smoothness threshold. The Low preset at 4K averages 93 FPS, but it sacrifices significant visual quality.

The data indicates that Medium is the best experience across all resolutions for this combo. It provides the highest average FPS with a playable minimum frame rate, while still retaining enough visual detail to appreciate the simulation's graphics. For users prioritizing frame rate above all else, Low at 1440p (178 FPS) or 1080p (282 FPS) are options, but Medium represents the sweet spot for balance.

How This Combo Ranks

The combination of the AMD Ryzen 5 8400F and AMD Radeon RX 7700 ranks 1,348 out of 3,002 tested combos in Pc Building Simulator. This places the combo in the 55th percentile of all tested systems, meaning it outperforms just over half of the configurations tested in this game. Given that the CPU and GPU are both mid-range parts, this ranking is consistent with expectations—the combo is not a top-tier performer but is far from the bottom.

The ranking suggests that this pair is capable of delivering a solid experience in Pc Building Simulator, but it doesn't excel to the level of higher-end configurations. The fact that the CPU's percentile vs all CPUs is 77 and the GPU's percentile vs all GPUs is 58 indicates that the CPU is comparatively stronger than the GPU in the broader hardware landscape. However, in this game, the combo's mid-pack ranking implies that the GPU's performance is more limiting than the CPU's, which aligns with the resolution scaling data showing significant FPS drops at 4K.

Relative to other combos, the 1,348th rank out of 3,002 means there is substantial headroom for improvement if either component were upgraded. The data suggests that pairing a stronger GPU with this CPU could yield better results in this game, as the CPU's benchmark scores suggest it could keep up with a more powerful graphics card. Conversely, the current GPU might be the bottleneck at higher settings, which is confirmed by the FPS behavior across presets.

Resolution Scaling

The FPS data reveals a clear pattern of scaling from 1080p to 4K, which indicates the limiting component. At Medium settings, the average FPS drops from 200 at 1080p to 126 at 1440p (a 37% decrease), and then to 66 at 4K (a 67% decrease from 1440p). This steep decline with increasing resolution is a classic indicator of GPU-bound performance. The CPU is capable of maintaining high frame rates at 1080p, as evidenced by the 282 FPS at Low settings, but as resolution increases and pixel count quadruples, the GPU's rendering workload becomes the dominant factor.

At High settings, the drop is similarly pronounced: 141 FPS at 1080p, 89 FPS at 1440p, and 47 FPS at 4K. The percentage drop from 1080p to 1440p is 37%, and from 1440p to 4K is 47%. At Ultra settings, the pattern continues with 134 FPS at 1080p, 85 FPS at 1440p, and 44 FPS at 4K, representing drops of 37% and 48%, respectively. The consistency of these percentage drops across settings strongly suggests that the GPU is the bottleneck, as the CPU's performance is not scaling with resolution in a way that would cause these FPS declines.

The Low settings data further supports this: 282 FPS at 1080p, 178 FPS at 1440p, and 93 FPS at 4K. Even at the lowest visual settings, the 4K resolution cuts performance by roughly two-thirds compared to 1080p. This is a clear sign that the GPU's raw pixel throughput is the limiting factor, not the CPU. The CPU's high single-thread scores and strong multi-thread performance indicate it has ample headroom to feed the GPU, but the GPU cannot keep up with the increasing pixel load at higher resolutions.

Measured FPS Breakdown

At 1920x1080, the combo delivers the following average FPS across settings: Low settings achieve 282 FPS, Medium achieves 200 FPS with a minimum of 170 and maximum of 230, High achieves 141 FPS, and Ultra achieves 134 FPS. These numbers indicate exceptional performance at 1080p, with even Ultra settings maintaining an average above 130 FPS. The Medium preset's minimum of 170 FPS ensures no noticeable stutter, making it ideal for high refresh rate monitors.

At 2560x1440, the performance remains strong: Low settings average 178 FPS, Medium averages 126 FPS with a minimum of 107 and maximum of 145, High averages 89 FPS, and Ultra averages 85 FPS. The Medium preset at 1440p provides a smooth experience for 120Hz displays, while High and Ultra are still playable on 60Hz monitors but may show occasional dips below 90 FPS in demanding scenes.

At 3840x2160, the performance drops significantly: Low settings average 93 FPS, Medium averages 66 FPS with a minimum of 56 and maximum of 76, High averages 47 FPS, and Ultra averages 44 FPS. At 4K, only Low and Medium settings are viable for smooth gameplay, with Medium providing a borderline 60 FPS experience and Low offering a more comfortable margin above it. High and Ultra settings at 4K are not recommended for consistent frame rates, as they fall below 50 FPS.

The data shows a consistent pattern: Medium settings provide the best balance of performance and quality at every resolution, with the minimum FPS being the key differentiator. At 1080p, the 170 FPS minimum means there's virtually no risk of frame drops affecting gameplay. At 1440p, the 107 FPS minimum is still well above 60 FPS. At 4K, the 56 FPS minimum is just below the 60 FPS threshold, meaning some users may notice occasional stutter.
