# Pc Building Simulator with AMD Ryzen 5 8400F + AMD Radeon RX 7700 XT

The AMD Ryzen 5 8400F paired with the AMD Radeon RX 7700 XT delivers a surprisingly robust experience in Pc Building Simulator, a simulation title that leans more on CPU logic than GPU spectacle. With the CPU sitting in the 77th percentile against all processors and the GPU in the 67th percentile, this combo lands at rank 1384 out of 3723 tested combinations. The measured data reveals a system that scales predictably across resolutions, but the real story lies in how the frame rates compress as you push toward 4K, exposing the GPU as the primary bottleneck at higher settings.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep but not catastrophic, which tells us exactly where the performance ceiling lives. At Low settings, the combo produces 309 FPS at 1920x1080, drops to 195 FPS at 2560x1440, and settles at 102 FPS at 3840x2160. That is a 67% reduction from 1080p to 4K, a decline that points squarely at the Radeon RX 7700 XT struggling to fill the pixel count at the highest resolution.

The scaling pattern shifts when you raise the quality preset. At Ultra settings, 1080p yields 147 FPS, 1440p drops to 93 FPS, and 4K falls to 49 FPS. The percentage loss from 1080p to 4K here is 67% again, but the absolute numbers tell a different story: the gap between Low and Ultra at 1080p is 162 FPS, while at 4K that same gap shrinks to just 53 FPS. This compression indicates that at 4K, the GPU is saturated regardless of the preset, making the resolution the dominant factor rather than the graphical workload.

Looking at the Medium preset, which includes min and max FPS data, the trend becomes clearer. At 4K Medium, the average is 72 FPS with a minimum of 61 and maximum of 83. At 1440p Medium, the average jumps to 138 FPS with a range of 118 to 159. At 1080p Medium, the average reaches 219 FPS with a spread from 186 to 252. The relative stability of the min-to-max range across resolutions—roughly 22 FPS at 4K, 41 FPS at 1440p, and 66 FPS at 1080p—suggests that CPU frame pacing remains consistent, but the GPU's headroom evaporates as resolution climbs.

The data indicates that 1440p is the sweet spot for this pairing. At High settings, 1440p produces 98 FPS, which is 64% of the 1080p High score of 155 FPS. That is a reasonable trade-off for the increased resolution. At 4K High, however, the 51 FPS average is barely playable for a simulation where precise mouse movements matter, and the 49 FPS at Ultra pushes it below the 60 FPS threshold that most users consider the baseline for smooth gameplay.

Settings Recommendations

The measured FPS rows provide a clear hierarchy for optimizing the experience. If the target is a locked 60 FPS at 4K, the only viable option is the Low preset, which delivers 102 FPS—plenty of headroom. The Medium preset at 4K hits 72 FPS, which is comfortably above 60, but the minimum of 61 FPS suggests occasional dips that could be noticeable in gameplay. For users who prioritize visual fidelity at 4K, Medium is the sensible choice, as it offers a 23 FPS improvement over High while still maintaining an average above 60.

At 1440p, the recommendation shifts to High settings. The 98 FPS average at High is 29 FPS above the 4K High score and only 40 FPS below the 1440p Low score of 195 FPS. The Ultra preset at 1440p yields 93 FPS, which is only 5 FPS below High, so the visual upgrade from High to Ultra comes at a minimal performance cost. Given that Ultra at 1440p still clears 90 FPS, it is the best balance of image quality and performance for users with 1440p monitors.

For 1080p, the story is less about hitting a playable threshold and more about maximizing refresh rate. The Ultra preset produces 147 FPS, which exceeds most 144Hz monitors' capabilities. The Medium preset at 219 FPS and Low at 309 FPS are overkill for standard displays but useful for high-refresh-rate panels. The data shows that even at Ultra, 1080p performance is so high that the CPU becomes the limiting factor, as evidenced by the smaller relative drop from High to Ultra (155 to 147 FPS) compared to the drop from Medium to High (219 to 155 FPS).

The minimum FPS values, available only for the Medium preset, provide insight into frame consistency. At 1080p Medium, the minimum of 186 FPS is 85% of the average, indicating solid stability. At 1440p Medium, the minimum of 118 FPS is 86% of the average. At 4K Medium, the minimum of 61 FPS is 85% of the average. This consistent ratio across resolutions suggests that the system's frame time variance scales proportionally, with no unexpected stutters at any resolution.

How This Combo Ranks

The comboRankInGame places this pairing at 1384 out of 3723 tested combinations, which puts it in the 63rd percentile of all CPU-GPU pairings tested in Pc Building Simulator. This is a mid-pack result, but the context matters: the game is simulation-heavy, and the Ryzen 5 8400F's multi-threaded performance is a significant contributor to the rank.

The CPU's avgBenchmarkScore of 25005 places it just 0.2% ahead of the AMD Ryzen 5 7500F (24964), 0.3% ahead of the Intel Core i7-11850H (24935), and 0.4% ahead of the Intel Core i7-13620H (24911). It trails the AMD EPYC 9474F (25103) by 0.4%. These are incredibly tight margins, meaning the 8400F is essentially performance-equivalent to its nearest rivals, with differences well within measurement noise.

On the GPU side, the Radeon RX 7700 XT's avgBenchmarkScore of 22549 is 0.5% ahead of the NVIDIA GeForce RTX 5060 Mobile (22435), 1.7% ahead of the AMD Radeon RX 5700 (22170), but 0.8% behind the NVIDIA GeForce RTX 4060 Mobile (22729) and 1.5% behind the NVIDIA GeForce RTX 2080 (22895). This places the GPU in a competitive but not dominant position, which aligns with its 67th percentile ranking among all GPUs.

Given these rival scores, the combo rank of 1384 out of 3723 suggests that the CPU-GPU pairing is well-balanced. The CPU's slight edge over its direct rivals compensates for the GPU's slight deficit against its competitors, resulting in a system that performs near the median of all tested combinations. For a simulation game that benefits from CPU throughput, this rank is respectable but not exceptional, indicating room for improvement with a stronger GPU if higher resolutions are the priority.

Measured FPS Breakdown

At 1920x1080, the measured FPS spans from 147 at Ultra to 309 at Low. The High preset delivers 155 FPS, while Medium produces 219 FPS with a minimum of 186 and maximum of 252. The progression from Low to Ultra shows a 162 FPS drop, which is a 52% reduction in performance when moving from the lightest to the heaviest preset.

At 2560x1440, the averages range from 93 at Ultra to 195 at Low. High settings yield 98 FPS, and Medium produces 138 FPS with a minimum of 118 and maximum of 159. The delta between Low and Ultra is 102 FPS, representing a 52% reduction, mirroring the 1080p scaling pattern almost exactly.

At 3840x2160, the numbers compress significantly. Low delivers 102 FPS, Medium averages 72 FPS with a range of 61 to 83, High drops to 51 FPS, and Ultra bottoms out at 49 FPS. The difference between Low and Ultra is just 53 FPS, a 52% reduction from Low, but the absolute gap is far smaller than at lower resolutions, confirming the GPU's saturation point.

The Medium preset is the only one with complete min and max data across all three resolutions. At 1080p, the range is 66 FPS (186 to 252); at 1440p, it is 41 FPS (118 to 159); at 4K, it is 22 FPS (61 to 83). This narrowing range with increasing resolution indicates that frame pacing becomes more consistent as the GPU becomes the bottleneck, reducing the CPU's ability to cause frame time spikes.

GPU Role

The Radeon RX 7700 XT brings 12 GB of GDDR6 memory on a 192-bit bus, yielding 432.0 GB/s of bandwidth. In Pc Building Simulator, this memory configuration proves sufficient even at 4K Ultra, where the 49 FPS average indicates the GPU is compute-limited rather than memory-limited. The 12 GB capacity is ample for a simulation game that does not stream massive textures, and the 432.0 GB/s bandwidth supports the frame rates observed without exhibiting memory pressure.

The GPU's clock speeds are notable: a base clock of 1435 MHz and a boost clock of 2544 MHz, with a game clock of 2171 MHz. The boost clock is 77% higher than the base clock, which is a substantial turbo range. In practice, this means the GPU can aggressively scale its frequency under load, which helps explain why the frame rates at 1080p Low (309 FPS) are so high—the GPU is likely running near its boost ceiling when the pixel workload is light.

The 5 nm process node and 28,100 million transistors on a 346 mm² die give the RX 7700 XT a transistor density of 81.2M per mm². This density enables the 35.17 TFLOPS FP32 performance, which is the raw compute throughput that drives the pixel and texture rates of 244.2 GPixel/s and 549.5 GTexel/s respectively. These figures align with the observed 4K performance: the GPU can push 49-51 FPS at the highest presets, which is consistent with a mid-range card's expected 4K capability in a non-demanding title.

The GPU's 96 ROPs and 216 TMUs handle the rasterization and texturing workloads. In a game like Pc Building Simulator, which likely involves UI-heavy rendering and 3D component models, the ROP count is sufficient for the observed frame rates. The RT cores (54) are present but likely unused in this game, as the simulation genre rarely employs ray tracing. The GPU's DirectX 12 Ultimate support ensures compatibility with modern APIs, though the game's 2019 release date means it likely uses DirectX 11 or 12, both of which the GPU handles comfortably.
