Pc Building Simulator

The AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 4080 delivers a robust experience in Pc Building Simulator, but the data reveals a clear pattern: this simulation title scales dramatically with resolution, and the RTX 4080 is the dominant factor in determining frame rates. At 1080p, the combo produces extremely high frame rates that exceed the needs of most displays, while at 4K, the demands of the simulation push the GPU to its limits, resulting in a playable but less fluid experience. This analysis breaks down the measured performance data, compares the combo against other tested configurations, and provides practical settings recommendations based on the benchmark results.

Resolution Scaling

The measured FPS data shows a steep performance curve as resolution increases, which is typical for a simulation game that emphasizes CPU logic but still relies heavily on the GPU for rendering. At 1920x1080, the combo achieves an average of 337 FPS on Low settings, 239 FPS on Medium, 169 FPS on High, and 161 FPS on Ultra. These numbers indicate that at 1080p, the system is almost certainly CPU-bound at lower settings, as the frame rates are so high that the RTX 4080 is not being fully utilized. The jump from Low to Ultra at 1080p only reduces the average FPS by 176 frames, showing that the GPU has ample headroom at this resolution.

Moving to 2560x1440, the average frame rates drop significantly across all settings. Low settings produce 213 FPS, Medium 151 FPS, High 106 FPS, and Ultra 101 FPS. This represents a reduction of roughly 37% to 41% compared to 1080p, which aligns with the increased pixel count. The gap between High and Ultra at 1440p narrows to just 5 FPS, suggesting that the Ultra preset is introducing diminishing returns in visual fidelity for the performance cost. The Medium preset at 1440p, with an average of 151 FPS and a minimum of 128 FPS, remains well above the threshold for smooth gameplay on high refresh rate monitors.

At 3840x2160, the performance hit becomes severe. The average FPS drops to 111 on Low, 79 on Medium, 56 on High, and 53 on Ultra. The scaling from 1440p to 4K is substantial, with the High preset losing 50 FPS and the Medium preset losing 72 FPS. This indicates that the RTX 4080 is becoming the primary bottleneck at 4K, as the increased resolution demands more pixel processing power. The fact that Low settings at 4K (111 FPS) still outperform High settings at 1440p (106 FPS) by a small margin is notable, showing that the GPU has significant compute resources that can be leveraged when the quality settings are reduced.

The difference between High and Ultra at 4K is only 3 FPS (56 vs 53), which is negligible in practice. This suggests that the Ultra preset is not well-optimized for this game at high resolutions, or that the visual improvements are not worth the performance cost. The data clearly shows that resolution is the primary determinant of performance, with the CPU playing a secondary role. At 1080p, the Ryzen 9 8945HX's 16 cores and 32 threads are more than sufficient to feed the GPU, but at 4K, the RTX 4080's workload becomes the limiting factor.

How This Combo Ranks

In the specific context of Pc Building Simulator, the AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 4080 combination ranks 908th out of 3002 tested combos. This places it in the top 31% of all configurations tested for this game, which is a respectable position given that the database likely includes many high-end desktop systems with more powerful GPUs. The ranking indicates that while this combo is competent, it is not at the very top of the performance hierarchy for this title.

The 908th rank out of 3002 combos suggests that there are many other configurations that achieve higher frame rates, likely due to more powerful desktop CPUs or GPUs. However, this is a mobile CPU (the Ryzen 9 8945HX is a 55W TDP part), and the RTX 4080 is a previous-generation GPU (released in 2022). Within the context of mobile platforms, this combo is strong, but it does not compete with the absolute top-tier desktop rigs that might appear in the database.

The data shows that the combo's performance is solid but not exceptional. The RTX 4080's 86th percentile ranking among GPUs is good, but its nearest rivals include the RTX 4080 SUPER (0.1% faster) and the AMD Radeon 8060S (2.7% faster). These small deltas indicate that the GPU is well-positioned in the market. The CPU's 95th percentile ranking among all CPUs is excellent, and its nearest rivals are all within 0.6% of its average score, showing that the Ryzen 9 8945HX is a top-tier processor in synthetic benchmarks.

For Pc Building Simulator specifically, the combo's rank of 908 suggests that the game is more GPU-bound at higher resolutions, which is consistent with the measured FPS data. The CPU's high performance does not translate into a top-100 ranking because the game's engine likely does not scale perfectly with 32 threads. The ranking reflects a balanced system that is capable but not dominant.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the combo delivers exceptional frame rates: 337 FPS on Low, 239 FPS on Medium, 169 FPS on High, and 161 FPS on Ultra. The Medium preset is the only one with recorded minimum and maximum FPS, showing 203 FPS and 275 FPS respectively, which indicates a stable frame delivery. The difference between High and Ultra at 1080p is only 8 FPS, suggesting that the Ultra preset offers marginal visual improvements over High.

At 2560x1440, the performance remains strong but drops noticeably. Low settings yield 213 FPS, Medium 151 FPS (with a minimum of 128 FPS and maximum of 173 FPS), High 106 FPS, and Ultra 101 FPS. The step from Medium to High results in a 45 FPS drop, which is the largest single-setting penalty at this resolution. This suggests that High settings introduce significant rendering effects that impact performance. The gap between High and Ultra is just 5 FPS, making Ultra a viable option for users who want the best visuals without a major performance hit.

At 3840x2160, the RTX 4080 is clearly working hard. Low settings produce 111 FPS, Medium 79 FPS (with a minimum of 67 FPS and maximum of 91 FPS), High 56 FPS, and Ultra 53 FPS. The drop from Low to Medium is 32 FPS, and from Medium to High is 23 FPS. The High and Ultra presets are nearly identical in performance, indicating that the Ultra preset may be adding effects that are not well-optimized or that the GPU is hitting a memory bandwidth limit. The minimum FPS of 67 at 4K Medium is still above 60 FPS, which is the threshold for smooth gameplay on most displays.

The data shows that the combo can handle 4K with reduced settings, but for the best experience, users should target 1440p or lower. At 1080p, the frame rates are so high that they exceed the refresh rate of most monitors, making the system effectively CPU-bound at that resolution. The measured FPS values are all averages, with minimums only recorded for the Medium preset, which limits the analysis of frame time consistency for other settings.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution and refresh rate. For users with a 1080p monitor, the High preset at 169 FPS is an excellent choice, providing a smooth experience that exceeds the capability of most 1440p or 4K displays. The Ultra preset at 161 FPS is also viable, offering a marginal visual upgrade for a small performance cost. The Medium preset at 239 FPS is overkill for most 1080p displays, but it provides a massive headroom for future-proofing or for users with 240Hz+ monitors.

For 1440p, the Medium preset at 151 FPS is the best balance of visual quality and performance. The minimum FPS of 128 ensures that even demanding scenes stay above 120 FPS, which is ideal for high refresh rate gaming. The High preset at 106 FPS is also acceptable for 1440p, especially for users with 144Hz monitors who prefer better visuals. The Ultra preset at 101 FPS is nearly identical to High, so there is no reason to choose High over Ultra unless you prefer the slightly lower performance. The Low preset at 213 FPS is only recommended for competitive play or for users who prioritize maximum frame rates over visual fidelity.

At 4K, the situation is more nuanced. The Medium preset at 79 FPS is the recommended choice, as it delivers a playable experience that stays above 60 FPS in most scenes, with a minimum of 67 FPS. The High preset at 56 FPS is borderline, and the Ultra preset at 53 FPS is not recommended for a smooth experience. The Low preset at 111 FPS is surprisingly good, but it sacrifices too much visual quality for a simulation game where detail matters. For 4K users, the Medium preset offers the best compromise, providing a smooth frame rate while retaining enough visual detail to enjoy the simulation aspects of the game.

The data suggests that the combo is best utilized at 1440p with Medium or High settings, or at 1080p with High or Ultra settings. The 4K experience is possible but requires accepting reduced settings or a lower frame rate. The RTX 4080's 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are sufficient for 4K, but the GPU's raw compute power (48.74 TFLOPS FP32) limits the ability to run the Ultra preset at that resolution.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture, codenamed Dragon Range. It has a base clock of 2.50 GHz and a boost clock of 5.40 GHz, with a 55W TDP. This is a high-end mobile CPU, and its benchmark scores reflect its capability: a Cinebench R23 multicore score of 42713 and a single-core score of 6030. The CPU's 95th percentile ranking among all CPUs confirms its strong performance, and its nearest rival, the Intel Core Ultra 9 285HX, is nearly identical in average score (0.1% difference).

In Pc Building Simulator, the CPU's role is significant but secondary to the GPU at higher resolutions. The game is a simulation, which typically involves complex logic and calculations, but the measured FPS data shows that the system is not CPU-bound at 1440p or 4K. At 1080p, the frame rates of 337 FPS on Low settings suggest that the CPU is capable of feeding the GPU at a very high rate, but the game's engine may not be able to fully utilize all 16 cores. The PassMark multithread score of 51405 and the Cinebench R15 multicore score of 4305 indicate strong multi-threaded performance, which is beneficial for simulation games that can spread workloads across threads.

The CPU's 64 MB of L3 cache and 83.2 GB/s memory bandwidth provide ample data throughput for the game's logic. The 5 nm process node and 13,140 million transistors place it in the latest generation of mobile processors. The fact that the combo ranks 908th out of 3002 suggests that the CPU is not the limiting factor in most scenarios, as other combos with less powerful CPUs likely achieve similar frame rates at lower resolutions. The CPU's high single-core performance (Cinebench R23 single-core score of 6030) is particularly important for simulation games, which often rely on a single main thread for game logic.

The data shows that the Ryzen 9 8945HX is more than capable of handling Pc Building Simulator's CPU demands, and its performance is not a bottleneck until the GPU is fully saturated. The CPU's 32 threads and high boost clock ensure that it can handle the game's simulation aspects without issue, even at 1080p where the GPU is less stressed. For users building a system around this combo, the CPU will not be a limiting factor in achieving the frame rates listed in the measured FPS data.
