Pc Building Simulator

Pc Building Simulator, a simulation title that tasks players with constructing and managing PCs, shows a distinct performance profile for the AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 4060 Mobile. The measured frame rates across resolutions and settings reveal a system that scales predictably with graphical load, but the data also suggests a nuanced balance between CPU and GPU capabilities that defines the experience at different quality levels.

Resolution Scaling

The frame rate progression from 1080p to 4K provides a clear picture of where the bottleneck lies. At 1080p with Low settings, the combo achieves an average of 237 FPS. Moving to 1440p drops this to 150 FPS, a reduction of 87 FPS or roughly 37%. Stepping up to 4K Low further reduces the average to 78 FPS, which is a 48% drop from the 1440p figure. This steep decline as resolution increases strongly indicates that the GPU is the primary limiting component as pixel count rises, with the CPU's 16 cores and 32 threads capable of feeding frames at a rate far exceeding what the RTX 4060 Mobile can render at higher resolutions.

The pattern holds true at Medium settings, though the absolute numbers are lower. At 1080p Medium, the average is 168 FPS, which falls to 106 FPS at 1440p—a 62 FPS difference. The 4K Medium result of 55 FPS is nearly half of the 1440p score. This consistent halving of performance with each resolution step-up suggests a system where the GPU's fill rate and memory bandwidth are being saturated. The RTX 4060 Mobile's 256.0 GB/s memory bandwidth and 128-bit bus width become increasingly stressed at 4K, explaining why the average FPS at 4K Medium (55) is less than a third of the 1080p Medium score (168).

Comparing High settings across resolutions reinforces this trend. The 119 FPS average at 1080p High drops to 75 FPS at 1440p, and then to just 39 FPS at 4K. The scaling factor from 1080p to 1440p is 0.63, and from 1440p to 4K is 0.52. This non-linear decline indicates that the GPU is not just becoming the bottleneck but is also hitting a performance cliff at 4K, likely due to the combination of the 8 GB VRAM capacity and the memory subsystem struggling with the higher resolution's demands.

The data implies that for this particular game, the CPU is never the limiting factor at any resolution. Even at 1080p Low, where the frame rate reaches 237 FPS, the Ryzen 9 8945HX's Cinebench R23 multi-core score of 42713 suggests it has ample headroom. The CPU's PassMark single-thread score of 3907 and multi-thread score of 51405 further support its ability to handle game logic and physics without bottlenecking. The question the data raises is whether this is a positive or negative trait. For a simulation game that might have complex background calculations, having a CPU that can maintain high minimum frame rates is beneficial, but the measured rows show no min FPS data for Low and High settings, leaving that aspect unexplored.

GPU Role

The NVIDIA GeForce RTX 4060 Mobile's specifications play a crucial role in the measured results. With a base clock of 1545 MHz and a boost clock of 1890 MHz, the GPU's performance is solid for a mobile part, but its 8 GB of GDDR6 memory on a 128-bit bus is a limiting factor at higher resolutions. The 256.0 GB/s bandwidth is adequate for 1080p and 1440p gaming, but the 4K results suggest the memory interface becomes a significant constraint.

The GPU's PassMark G3D score of 17469 places it in the 67th percentile of all GPUs, indicating it is a mid-range performer. Its nearest rival in the benchmark database is the NVIDIA GeForce RTX 2080, which scores 22895, a delta of -0.7%. This close comparison suggests that the RTX 4060 Mobile is roughly equivalent to a desktop RTX 2080 in raw compute, but the mobile form factor's power constraints (115 W TDP) may limit sustained performance. The 11.61 TFLOPS FP32 performance is respectable, but the 48 ROPs and 96 TMUs are relatively low counts for handling 4K resolution, where pixel throughput is critical.

Looking at the 4K Ultra result of 37 FPS, it is clear that the GPU is overwhelmed. The 24 RT cores and 96 tensor cores do not provide significant benefit in this simulation title, which likely does not heavily utilize ray tracing or DLSS. The game's genre suggests it is more about CPU-side logic and system monitoring, making the GPU's rasterization performance the key factor. The data shows that at 4K, the RTX 4060 Mobile can only deliver playable frame rates at Low settings (78 FPS), with Medium (55 FPS) being borderline and High (39 FPS) and Ultra (37 FPS) being too low for smooth gameplay.

The GPU's memory configuration is particularly telling. The 8 GB VRAM is becoming the standard for mobile GPUs, but the 128-bit bus width limits the effective bandwidth. At 4K, textures and frame buffers require more memory, and the system may be resorting to PCIe 4.0 x8 transfers, which could introduce stuttering. The measured min FPS data is only available for Medium settings, showing 47 FPS at 4K and 143 FPS at 1080p, suggesting that the frame pacing is acceptable at Medium but may degrade at other settings.

Settings Recommendations

Based on the measured FPS rows, the optimal experience depends heavily on the target resolution and desired frame rate. For 1080p gaming, the data shows that Ultra settings (113 FPS) are achievable, but High (119 FPS) offers nearly identical performance with a slight edge. The 6 FPS difference between High and Ultra is minimal, suggesting that players can enable Ultra without a significant penalty. The Medium setting at 168 FPS is overkill for most displays, and Low at 237 FPS is only useful for extreme refresh rate monitors.

At 1440p, High settings (75 FPS) provide a smooth experience for most players, while Ultra (71 FPS) is nearly identical. The 4 FPS difference means there is no reason to choose High over Ultra if visual quality is a priority. Medium (106 FPS) offers a significant boost for high refresh rate displays, and Low (150 FPS) is only recommended for competitive play or if the user has a 144Hz+ monitor. The data suggests that 1440p Ultra is the sweet spot, balancing visual fidelity with playable frame rates.

For 4K, the situation is more constrained. Low (78 FPS) is the only setting that provides consistently smooth gameplay, with Medium (55 FPS) being playable but not ideal for fast-paced action. High (39 FPS) and Ultra (37 FPS) are not recommended for 4K, as they fall below the 60 FPS threshold that most users consider acceptable. The data indicates that 4K gaming with this combo requires sacrificing visual quality, and even then, the frame rates are not impressive. The recommendation is to stick with 1440p for this game if visual fidelity is important, or 1080p if maximum smoothness is the goal.

Measured FPS Breakdown

The complete set of measured FPS values provides a comprehensive view of the combo's performance. At 1920x1080, the results are as follows: Low settings yield an average of 237 FPS, Medium yields 168 FPS (with a min of 143 and max of 193), High yields 119 FPS, and Ultra yields 113 FPS. The progression from Low to Ultra shows a 52% reduction in frame rate, which is a reasonable scaling for a simulation game that likely has moderate graphical demands.

At 2560x1440, the averages are: Low at 150 FPS, Medium at 106 FPS (min 90, max 122), High at 75 FPS, and Ultra at 71 FPS. The drop from 1080p to 1440p is significant, with the High setting losing 44 FPS (from 119 to 75). This suggests that the GPU's shading units and TMUs are being taxed more heavily, but the 8 GB VRAM is still sufficient at this resolution.

At 3840x2160, the averages are: Low at 78 FPS, Medium at 55 FPS (min 47, max 64), High at 39 FPS, and Ultra at 37 FPS. The 4K results show a dramatic falloff, with Ultra being only 3 FPS lower than High, indicating that the GPU is completely saturated. The difference between Medium and High is 16 FPS, which is the largest gap between consecutive settings at 4K, suggesting that the High preset introduces effects that are particularly demanding on the memory subsystem.

The min FPS data for Medium settings across all resolutions provides insight into frame pacing. At 1080p, the min of 143 FPS is 85% of the average, indicating a stable experience. At 1440p, the min of 90 FPS is 85% of the average, again showing consistency. At 4K, the min of 47 FPS is 85% of the average, which is acceptable but indicates that there are occasional dips that could be noticeable. The lack of min/max data for other settings leaves a gap in the analysis, but the available numbers suggest that the Medium preset is well optimized for this game.

How This Combo Ranks

The AMD Ryzen 9 8945HX + NVIDIA GeForce RTX 4060 Mobile combination ranks 2276 out of 3723 tested combos for Pc Building Simulator. This places it in the 61st percentile, meaning it outperforms 61% of all tested configurations. The rank is somewhat surprising given the CPU's high performance (95th percentile among all CPUs) and the GPU's mid-range position (67th percentile). This suggests that the game is not heavily CPU-dependent, or that the GPU's limitations at higher resolutions are dragging down the overall ranking.

The CPU's nearest rivals provide context for its individual performance. The Intel Core Ultra 9 285HX scores 76155, which is 0.1% higher than the Ryzen 9 8945HX's 76212 average benchmark score. The AMD EPYC Embedded 8224P and AMD Ryzen Threadripper PRO 9945WX both score slightly higher (76492 and 76513 respectively), but the deltas are all within 0.6%, indicating that the CPU is on par with top-tier desktop and mobile processors. The Ryzen 9 9950X3D scores 75779, which is 0.6% lower, showing that the 8945HX is competitive even against flagship gaming CPUs.

The GPU's nearest rivals show a similar picture. The RTX 4060 Mobile's average benchmark score of 22729 is 0.7% lower than the desktop RTX 2080 (22895), 0.8% higher than the AMD Radeon RX 7700 XT (22549), and 1.3% lower than the Intel Arc B580 (23021). The RTX 5060 Mobile scores 22435, which is 1.3% lower. This clustering indicates that the mobile GPU is roughly equivalent to desktop mid-range cards from the previous generation, but its mobile form factor limits its sustained performance.

The combo rank of 2276 suggests that while the individual components are strong, the pairing may not be optimal for this specific game. The high CPU performance is not fully utilized, and the GPU becomes the bottleneck at higher resolutions. The data implies that a less powerful CPU paired with a stronger GPU would likely rank higher in this game, as the simulation genre does not appear to leverage the CPU's 16 cores and 32 threads to their full potential.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture, codenamed Dragon Range. With a base clock of 2.50 GHz and a boost clock of 5.40 GHz, it offers substantial single-threaded and multi-threaded performance. Its Cinebench R23 scores of 42713 (multi-core) and 6030 (single-core) place it in the 95th percentile of all CPUs, indicating that it is a top-tier mobile processor. The PassMark single-thread score of 3907 and multi-thread score of 51405 further confirm its capabilities.

In Pc Building Simulator, the CPU's role appears to be secondary to the GPU. The measured frame rates at 1080p Low (237 FPS) suggest that the CPU can handle the game's logic without breaking a sweat, but the GPU cannot keep up with the CPU's frame generation potential. The 64 MB of L3 cache and 83.2 GB/s memory bandwidth provide ample data throughput for game state updates, but the game's simulation nature means that most of the work is done in the CPU's arithmetic logic units rather than its cache hierarchy.

The CPU's nearest rivals show that it is competitive with the best processors available. The Intel Core Ultra 9 285HX scores only 0.1% higher in average benchmark, while the AMD Ryzen 9 9950X3D scores 0.6% lower. This suggests that the 8945HX is not the limiting factor in this combo. The data implies that the game's performance is constrained by the GPU's rendering capabilities, not the CPU's processing power. For players who prioritize high frame rates at 1080p, the CPU is more than sufficient, but the RTX 4060 Mobile becomes the bottleneck at higher resolutions.

The CPU's 55 W TDP and 5 nm process node (TSMC) make it an efficient processor for mobile use, but the game does not appear to stress it heavily. The simulation genre typically involves more complex AI and physics calculations than fast-paced shooters, but the measured FPS at 1080p Low (237) is high enough that the CPU is clearly not the limiting factor. The data suggests that players with this combo should focus on GPU settings to optimize their experience, as the CPU has ample headroom to handle any in-game simulation tasks without affecting frame rates.
