The MX570 comparison is notable because it suggests the RTX 4080 Mobile's performance profile is competitive even against significantly different class parts.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest performance. Low settings produce an average of 337 FPS, while Medium settings yield 239 FPS with a minimum of 203 FPS and maximum of 275 FPS. High settings drop to 169 FPS average, and Ultra settings produce 161 FPS. The gap between Low and Ultra is approximately 176 FPS, indicating that settings have a significant impact at this resolution.

Moving to 2560x1440, performance remains robust but scales down proportionally. Low settings average 213 FPS, Medium averages 151 FPS with a range of 128-173 FPS, High averages 106 FPS, and Ultra averages 101 FPS. The difference between 1080p and 1440p at each setting level shows roughly a 37-40% reduction in frame rate across most presets, though the Low setting drops by 37% and Ultra by 37%.

At 3840x2160, the system still delivers playable frame rates across all settings. Low averages 111 FPS, Medium averages 79 FPS with a range of 67-91 FPS, High averages 56 FPS, and Ultra averages 53 FPS. The 4K results show the GPU beginning to become a limiting factor, particularly at High and Ultra settings where frame rates approach 50-60 FPS territory. The min FPS of 67 at 4K Medium indicates that even momentary dips remain well above playable thresholds.

The scaling from 1080p to 4K shows a consistent pattern: at Low settings, FPS drops from 337 to 111 (a 67% reduction); at Medium, from 239 to 79 (67% reduction); at High, from 169 to 56 (67% reduction); and at Ultra, from 161 to 53 (67% reduction). This uniform scaling across settings suggests the performance bottleneck shifts consistently with resolution rather than being tied to specific graphics features.

How This Combo Ranks

The combination ranks 1188th out of 3723 tested combos in Pc Building Simulator, placing it in the 68th percentile of all systems. This means approximately 32% of tested configurations outperform it, while 68% perform worse. Given the game's simulation nature and modest graphical demands, this ranking reflects the overall capability of the CPU-GPU pair rather than any specific optimization for this title.

The ranking position is notable because both components individually rank highly — the CPU in the 95th percentile and GPU in the 81st percentile. The combo ranking being lower than either component's individual percentile suggests that other systems with more powerful GPUs or CPUs may achieve higher frame rates in this game, though the measured results show this combo already delivers excellent performance at all tested settings.

Compared to the nearest rival combos by component score, this system performs consistently with expectations. The CPU's near-tie with the Intel Core Ultra 9 285HX and GPU's near-tie with the RTX 5080 Mobile suggest that swapping either component for its closest rival would produce negligible differences in actual gameplay. The 3723 total combos tested provide a broad comparison base, and ranking in the top third indicates this is a well-matched pair for the game's requirements.

Settings Recommendations

Based on the measured frame rates, the optimal settings preset depends on the target resolution. At 1920x1080, Ultra settings at 161 FPS are the best choice for maximum visual quality while maintaining frame rates well above any competitive threshold. The 75 FPS drop from Medium to Ultra is substantial, but 161 FPS remains smooth on any modern display.

At 2560x1440, Medium settings at 151 FPS provide the strongest balance between visual fidelity and performance. The minimum frame rate of 128 FPS ensures no perceptible stuttering, while the 151 FPS average leaves headroom for demanding scenes. Ultra at 101 FPS is also viable for users prioritizing image quality, but the 50 FPS advantage of Medium makes it the recommended choice for most users.

At 3840x2160, Medium settings at 79 FPS are the recommended preset. The minimum of 67 FPS remains above the 60 FPS threshold for smooth gameplay, while the 79 FPS average provides comfortable margin. High settings at 56 FPS are playable but risk dropping below 60 FPS in demanding moments, and Ultra at 53 FPS should be avoided for consistent performance. Low at 111 FPS is available for users who prioritize frame rate over visual quality.

For users with high refresh rate displays at 1080p, the Low setting at 337 FPS and Medium at 239 FPS both exceed 240 Hz capabilities, making Medium the better choice for visual quality without sacrificing refresh rate headroom. At 1440p, the 213 FPS Low setting similarly supports high refresh rates, but Medium at 151 FPS still exceeds 144 Hz displays.

Resolution Scaling

The frame rate scaling from 1080p to 4K follows a remarkably consistent pattern across all settings presets. At every quality level, the transition from 1920x1080 to 2560x1440 reduces frame rates by approximately 37%, and the transition from 1440p to 4K reduces them by another 47%. This compounding effect means 4K performance is roughly 67% lower than 1080p performance at every settings level.

This uniform scaling pattern indicates that the GPU is the primary limiting factor as resolution increases. The CPU's strong single-thread and multi-thread performance ensures it can feed the GPU adequately at all resolutions, but the RTX 4080 Mobile's 12 GB VRAM and 432.0 GB/s bandwidth become increasingly stressed at higher pixel counts. The fact that Low settings scale identically to Ultra settings (both dropping 67% from 1080p to 4K) suggests that resolution-dependent overhead dominates the performance equation rather than specific graphics features.

The measured results show that the combo maintains playable frame rates at all resolutions and settings, with the lowest result being 53 FPS at 4K Ultra. The data indicates that 4K gaming is viable on this system, particularly at Medium settings where the 79 FPS average provides a comfortable experience. Users targeting 4K should prioritize Medium settings to maintain smooth gameplay, while 1080p and 1440p users can freely choose between Ultra quality and maximum frame rates based on their display capabilities and personal preferences.
