Pc Building Simulator

The AMD Ryzen 5 8400F and AMD Radeon RX 5700 XT combination delivers measured performance in Pc Building Simulator across three resolutions and four presets. The CPU, a 6-core 12-thread Zen 4 part with a boost clock of 4.70 GHz, and the GPU, an 8 GB GDDR6 RDNA 1.0 card with a boost clock of 1905 MHz, produce the frame rates detailed below. The CPU carries a launch MSRP of $170, and the GPU a launch MSRP of 399 USD. Benchmark results indicate that this pairing is capable of smooth gameplay at 1080p and 1440p, while 4K requires a careful preset choice.

Settings Recommendations

The measured FPS rows show a clear hierarchy across presets. At 1920x1080, the Ultra preset averages 103.3 FPS, which is well above the 60 FPS threshold for fluid simulation gameplay. High averages 112.4 FPS, Medium 159 FPS, and Low 222.9 FPS. Since even the most demanding preset clears 100 FPS, the best experience at 1080p is the Ultra preset—there is no reason to sacrifice visual quality when the headroom is this large. The data shows that the GPU is not a limiting factor at this resolution, and the CPU’s strong single-thread performance (Cinebench R23 single-core score of 2943) helps maintain high frame rates.

At 2560x1440, the picture changes. Ultra averages 66.4 FPS, which is still above 60 but leaves little margin for scene complexity. High averages 68.2 FPS, nearly identical to Ultra, while Medium jumps to 96.6 FPS and Low reaches 140.6 FPS. For a consistently smooth experience, Medium is the recommended preset at 1440p: it delivers 96.6 FPS, a 45% improvement over Ultra’s 66.4 FPS, while still offering a substantial visual upgrade over Low. High and Ultra are playable, but the extra load on the GPU (8 GB VRAM, 448.0 GB/s bandwidth) shows diminishing returns—the difference between High and Ultra is only 1.8 FPS, so choosing Ultra over High adds no practical benefit.

At 3840x2160, the GPU becomes the primary bottleneck. Low averages 73.3 FPS, Medium 53.8 FPS, High 38.2 FPS, and Ultra 33 FPS. Only Low clears the 60 FPS bar. Medium falls below 60, and High/Ultra are not viable for smooth play. Therefore, the best experience at 4K is the Low preset, which provides 73.3 FPS—a playable frame rate that still allows the simulation to run without stutter. Users who prioritize visual fidelity over frame rate could accept Medium’s 53.8 FPS, but the data suggests that Low is the only preset that meets a standard 60 FPS target.

GPU Role

The AMD Radeon RX 5700 XT is built on the RDNA 1.0 architecture with 8 GB of GDDR6 memory on a 256-bit bus, yielding a bandwidth of 448.0 GB/s. Its base clock is 1605 MHz, game clock 1755 MHz, and boost clock 1905 MHz. These specifications directly influence the measured frame rates. The GPU’s average benchmark score of 24731 places it in the 68th percentile of all GPUs, and its nearest rivals include the NVIDIA RTX A5000 Mobile (deltaPct -0.1), Intel Arc A350M (deltaPct 0.3), NVIDIA GeForce RTX 5060 Mobile (deltaPct 0.6), and NVIDIA Quadro RTX 5000 (deltaPct 0.9). This means the RX 5700 XT is within 0.9% of the Quadro RTX 5000 in average score, indicating a tightly clustered performance band.

In Pc Building Simulator, the GPU’s role becomes evident as resolution increases. At 1080p, the GPU is not stressed—even Ultra averages 103.3 FPS, and the CPU’s 6-core/12-thread design (Cinebench R23 multicore score of 20851) is sufficient to feed the card. At 1440p, the GPU begins to matter more: the drop from Medium (96.6 FPS) to Ultra (66.4 FPS) shows that the card’s shading units (2560) and texture units (160) are being pushed. At 4K, the GPU is clearly the limiting component—the 8 GB VRAM and 448.0 GB/s bandwidth are not enough to maintain high frame rates on High or Ultra, as evidenced by the 38.2 and 33 FPS averages. The GPU’s pixel rate of 121.9 GPixel/s and texture rate of 304.8 GTexel/s are adequate for lower presets, but the 4K Ultra result of 33 FPS indicates that the card’s compute throughput (9.754 TFLOPS FP32) is insufficient for the highest settings at that resolution.

Resolution Scaling

The measured FPS data shows a consistent decline as resolution increases, but the magnitude varies by preset. At High settings, the average FPS falls from 112.4 at 1080p to 68.2 at 1440p and 38.2 at 4K. That is a drop of 44.2 FPS from 1080p to 1440p, and another 30 FPS from 1440p to 4K. At Medium, the progression is 159 → 96.6 → 53.8, a similar pattern. At Low, the numbers are 222.9 → 140.6 → 73.3, showing that even the least demanding preset loses more than half its frame rate when moving from 1080p to 4K. At Ultra, the drop is 103.3 → 66.4 → 33, with the 4K result being less than one-third of the 1080p value.

This scaling pattern indicates that the GPU is the primary bottleneck at higher resolutions. The CPU’s performance is relatively constant across resolutions—its 3DMark single-thread score of 951 and Cinebench R23 single-core score of 2943 suggest it can handle the simulation’s logic regardless of pixel count. The GPU, however, must render more pixels, and its 8 GB VRAM and 256-bit bus become strained. The fact that Low at 4K (73.3 FPS) is still higher than Ultra at 1440p (66.4 FPS) underscores that the GPU’s fill rate and memory bandwidth are the deciding factors. For users targeting 4K, the data suggests that only the Low preset provides a playable experience, while 1440p offers a wider range of viable settings.

How This Combo Ranks

In the database of tested combos for Pc Building Simulator, this pairing ranks 1349th out of 1769 combinations. That places it in the lower portion of the field, despite the individual components’ respectable percentiles. The CPU’s percentileVsAllCpus is 82, meaning it outperforms 82% of all CPUs in the database, and its average benchmark score of 25064 is within 0.3% of the AMD Ryzen 5 7500F (deltaPct 0.3) and within 0.1% of the AMD Ryzen 7 2700X (deltaPct 0). The GPU’s percentileVsAllGpus is 68, with an average score of 24731, placing it near the NVIDIA RTX A5000 Mobile (deltaPct -0.1) and Intel Arc A350M (deltaPct 0.3).

The low combo rank suggests that while each part is above average, the combination is not optimized for this specific game. The simulation genre often favors CPU performance, and the Ryzen 5 8400F’s 6 cores and 12 threads are sufficient, but the RX 5700 XT’s 8 GB VRAM and RDNA 1.0 architecture may not be the best match for the game’s rendering demands at higher resolutions. The measured FPS data confirms that the combo excels at 1080p and 1440p Medium, but struggles at 4K. Compared to other combos in the database, this pairing is likely held back by the GPU’s age (released 2019-07-06) and its end-of-life production status. The CPU, released 2024-03-31, is newer and more capable, but the GPU’s limitations cap the overall performance.
