Pc Building Simulator

Pc Building Simulator presents an interesting case study for the AMD Ryzen AI Max+ 395 paired with the NVIDIA GeForce RTX 4070 Mobile. The measured frame rates across resolutions and settings reveal a configuration that is heavily influenced by the graphics card, particularly at higher resolutions, while the processor provides ample headroom to avoid becoming the primary constraint.

Resolution Scaling

The data shows a clear and predictable pattern: average frame rates decline as resolution increases from 1920x1080 to 3840x2160. This is entirely expected, as higher resolutions demand more pixel-pushing power from the GPU. The most telling comparison is at the High preset, where the average FPS drops from 133 at 1920x1080 to 84 at 2560x1440, and then further to 44 at 3840x2160. This represents a significant 67% reduction in performance from the lowest to the highest resolution tested.

The scaling curve between resolutions is not linear. Moving from 1080p to 1440p at High settings results in a 49 FPS drop, while moving from 1440p to 4K results in a 40 FPS drop. This suggests that the GPU is beginning to hit its limits more aggressively at 4K, as the workload becomes increasingly dominated by fragment shading and memory bandwidth rather than geometry processing. The RTX 4070 Mobile's 8 GB of GDDR6 memory and 256.0 GB/s bandwidth are likely being stressed at the higher resolutions.

At the Low preset, the pattern is even more pronounced. The average FPS at 1920x1080 is 266, which drops to 168 at 2560x1440 and 88 at 3840x2160. The fact that the 4K Low setting still achieves a playable 88 FPS indicates that the CPU is not a limiting factor in this scenario. The scaling from 1440p to 4K at Low is a 80 FPS drop, which is a larger absolute decrease than at High settings, further emphasizing the GPU's role as the bottleneck when the graphical load is lowered.

The Medium preset provides the only complete set of min and max FPS data, offering insight into frame time consistency. At 3840x2160, the average is 62 FPS with a min of 53 and max of 72, a spread of 19 FPS. At 2560x1440, the average is 119 FPS with a range of 101 to 137 (36 FPS spread). At 1920x1080, the average is 189 FPS with a range of 160 to 217 (57 FPS spread). This data indicates that while the average frame rate scales down with resolution, the variance in frame times also decreases, suggesting more consistent performance at lower resolutions where the GPU is less stressed.

CPU Role

The AMD Ryzen AI Max+ 395 is a 16-core, 32-thread processor based on the Zen 5 architecture. It boasts a base clock of 3.00 GHz and a boost clock of 5.10 GHz. Its benchmark scores are substantial; for instance, it achieves a Cinebench R23 multicore score of 35314 and a Geekbench multicore score of 20992. These results place it in the 95th percentile of all CPUs, indicating top-tier processing capability.

In the context of Pc Building Simulator, a simulation game, the CPU's role is to handle the game's logic, system calculations, and the simulation of PC components. The data suggests that the Ryzen AI Max+ 395 has more than enough compute power for this task. The fact that the average FPS at 1920x1080 Low is 266 FPS, which is a very high frame rate, indicates that the CPU is not bottlenecking the system at lower resolutions where the GPU has less work to do.

The CPU's 64 MB of shared L3 cache and quad-channel memory support (with a total bandwidth of 256.0 GB/s) likely help in feeding the GPU with data efficiently, especially in a game that simulates many concurrent objects and states. The high PassMark multithread score of 54934 and the 95th percentile ranking against all CPUs reinforce the notion that this processor is a strong partner for a mid-to-high-end mobile GPU. The data shows that even at 4K Ultra, where the GPU is most stressed, the CPU is still able to maintain a 42 FPS average, confirming it is not the primary limiting component.

GPU Role

The NVIDIA GeForce RTX 4070 Mobile is the other half of this combo. It is based on the Ada Lovelace architecture and features 4608 shading units, 144 texture mapping units, and 48 raster output pipelines. It has a base clock of 1395 MHz and a boost clock of 1695 MHz. Its memory configuration is 8 GB of GDDR6 on a 128-bit bus, providing a bandwidth of 256.0 GB/s.

The GPU's benchmark scores, such as a PassMark G3D score of 19587, place it in the 73rd percentile of all GPUs. Its nearest rivals include the AMD Radeon RX 6700 XT (with a 0% delta) and the NVIDIA GeForce RTX 3090 (with a -0.5% delta), indicating that its raw compute performance is comparable to those desktop-class cards. However, its mobile form factor and 115 W TDP mean it is designed for laptops, and its performance is still bound by the system's cooling and power delivery.

In Pc Building Simulator, the GPU's role is to render the 3D environment, manage visual effects, and handle the graphical interface. The measured FPS data clearly shows that the RTX 4070 Mobile is the bottleneck at higher resolutions and settings. At 3840x2160 Ultra, the average FPS is 42, which is below the 60 FPS threshold often considered smooth. At 2560x1440 Ultra, the average is 80 FPS, which is more comfortable, and at 1920x1080 Ultra, it reaches 127 FPS.

The performance delta between Low and Ultra presets is stark. At 1080p, the difference is 139 FPS (from 266 to 127), and at 4K, the difference is 46 FPS (from 88 to 42). This demonstrates that the GPU's compute and memory subsystems are heavily taxed by the higher graphical demands of the Ultra preset, particularly at higher resolutions. The 8 GB VRAM is likely sufficient for this simulation game at these settings, but the data suggests that the card's raw throughput is the limiting factor.

How This Combo Ranks

The combination of the AMD Ryzen AI Max+ 395 and the NVIDIA GeForce RTX 4070 Mobile is ranked 2006 out of 3723 tested combos in this game. This places it in the upper-middle tier of all hardware combinations tested on the benchmark database. It is not a top-tier combo, but it is far from the bottom, indicating that it offers a solid level of performance for a mobile platform.

The ranking is likely influenced by the fact that the RTX 4070 Mobile, while capable, is not a flagship GPU. Its 73rd percentile ranking among all GPUs is lower than the CPU's 95th percentile ranking among all CPUs. This imbalance means the combo's overall performance is capped by the GPU, which is consistent with the data showing the GPU as the primary bottleneck at higher resolutions.

Compared to other combos in the database, this pairing sits just past the halfway point. This suggests that there are many systems with more powerful GPUs that can push higher frame rates at 4K, but this combo still provides a very good experience at 1080p and 1440p. The CPU's strength ensures that the system will not feel sluggish in CPU-intensive tasks or at lower resolutions, making it a balanced, if not top-tier, mobile gaming solution.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the average frame rates are as follows: Low yields 266 FPS, Medium yields 189 FPS (with a min of 160 and max of 217), High yields 133 FPS, and Ultra yields 127 FPS. This shows that at 1080p, the system is capable of very high refresh rate gaming on the Low and Medium presets, and it can still achieve over 120 FPS on High and Ultra.

Moving to 2560x1440, the performance scales down. The Low preset averages 168 FPS, Medium averages 119 FPS (min 101, max 137), High averages 84 FPS, and Ultra averages 80 FPS. This resolution is the sweet spot for this combo, as it offers a great balance between visual fidelity and performance, with the Medium and High presets providing smooth gameplay above 80 FPS.

At 3840x2160, the GPU becomes the clear limiting factor. The Low preset averages 88 FPS, which is still playable, but the Medium preset drops to 62 FPS (min 53, max 72), and the High and Ultra presets fall to 44 and 42 FPS, respectively. The data indicates that 4K gaming is only comfortable at the Low or Medium settings, and even then, the frame rates are not as high as what a desktop GPU might achieve.

Settings Recommendations

Based on the measured rows, the optimal settings for this combo depend on the user's target resolution and desired frame rate. For users with a 1920x1080 display, the Ultra preset is the best choice, as it provides an average of 127 FPS, which is well above the 60 FPS threshold and close to the 144 Hz refresh rate that many monitors offer. The drop from High to Ultra is a marginal 6 FPS, so there is little reason not to use the highest settings.

For 2560x1440 displays, the High preset is recommended for a balanced experience. It delivers an average of 84 FPS, which is smooth for most players. The Ultra preset only offers a 4 FPS reduction to 80 FPS, so some users might prefer Ultra for the extra visual details. However, the Medium preset at 119 FPS is the best choice for users who prioritize high refresh rates, as it nearly doubles the performance of Ultra.

At 3840x2160, the data suggests that the Medium preset is the highest setting that should be used for a playable experience, with an average of 62 FPS. The Low preset offers 88 FPS for a more responsive feel, but the visual quality is compromised. The High and Ultra presets, with averages of 44 and 42 FPS, are not recommended for 4K gaming, as they fall below the 60 FPS target and may result in a less fluid experience.
