Downfall

# Downfall with Intel Core Ultra 5 125H + NVIDIA GeForce RTX 4080

The Intel Core Ultra 5 125H paired with the NVIDIA GeForce RTX 4080 delivers a playable experience across all tested resolutions in Downfall, but the performance curve reveals a system that leans heavily on the GPU at higher settings while the CPU shows its limits at lower presets. This mobile processor, part of the Core Ultra Series 1 with Meteor Lake architecture, combines 14 cores and 18 threads with a boost clock of 4.50 GHz, while the RTX 4080 brings 16 GB of GDDR6X memory and Ada Lovelace architecture to the table. The measured frame rates show a clear pattern: at 1080p Low the combo hits 287 FPS, but at 4K Ultra it drops to 53 FPS, a spread that tells the story of where each component's headroom begins and ends.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all four settings presets, indicating that Downfall's rendering load scales aggressively with pixel count. At Low settings, the average frame rate falls from 287 FPS at 1920x1080 to 205 FPS at 2560x1440, then to 127 FPS at 3840x2160 — that is a 44% reduction from 1080p to 1440p and a further 38% reduction from 1440p to 4K. At High settings, the pattern repeats: 192 FPS at 1080p, 137 FPS at 1440p, and 85 FPS at 4K. The Medium preset shows 235 FPS at 1080p, 168 FPS at 1440p, and 104 FPS at 4K, while Ultra drops from 120 FPS at 1080p to 86 FPS at 1440p and finally to 53 FPS at 4K.

These scaling patterns suggest the GPU is the primary bottleneck as resolution increases, which is expected given the RTX 4080's 256-bit memory bus and 716.8 GB/s bandwidth. The fact that even at 4K Low the system still produces 127 FPS indicates substantial GPU headroom for a horror title of Downfall's era, but the Ultra preset at 4K falling to 53 FPS shows that the combination of maximum settings and 4K resolution overwhelms the graphics pipeline. The gap between Low and Ultra at each resolution grows as resolution increases: at 1080p the difference is 167 FPS (287 vs 120), at 1440p it is 119 FPS (205 vs 86), and at 4K it narrows to 74 FPS (127 vs 53). This shrinking delta implies that at lower resolutions the CPU and memory subsystem contribute more to frame rate variability, while at 4K the GPU's pixel throughput becomes the dominant constraint.

GPU Role

The NVIDIA GeForce RTX 4080 in this combo is a mobile variant that still carries the full AD103 chip with 9,728 shading units, 304 texture mapping units, and 112 raster output pipelines. Its boost clock of 2505 MHz and base clock of 2205 MHz, combined with 16 GB of GDDR6X memory running at 22.4 Gbps effective, provide the raw throughput needed to sustain the frame rates measured in Downfall. The GPU's 48.74 TFLOPS of FP32 compute and 280.6 GPixel/s pixel rate explain why the card can push 287 FPS at 1080p Low — the pixel fill rate is more than sufficient for that resolution, and the shading units handle the horror game's effects without breaking a sweat.

VRAM usage is not directly measured in the data, but the 16 GB capacity is more than adequate for Downfall, a game released in 2016 when 4 GB graphics memory was common. The 716.8 GB/s memory bandwidth ensures that texture streaming at 4K Ultra does not become a limiting factor, which is supported by the fact that the 4K Ultra result of 53 FPS is likely compute-bound rather than memory-bound. The RTX 4080's percentile ranking of 86 among all GPUs, with an average benchmark score of 54,247, places it near the top of the performance stack, and its nearest rivals include the RTX 4080 SUPER (0.1% difference) and AMD Radeon Pro W5700X (-1.1% difference). Those tiny deltas indicate that this GPU is essentially at parity with the SUPER variant in synthetic benchmarks, yet the measured Downfall results show the 4080 handling the game's demands without any signs of thermal throttling or clock instability.

The GPU's 320 W TDP and triple-slot design suggest this is a high-power mobile part, and the combination of 76 RT cores and 304 tensor cores means Downfall's lighting and shadow effects — likely using DirectX 12 Ultimate features — are processed efficiently. The passmark DirectX 12 score of 132 and DirectX 11 score of 314 indicate that the card excels in modern API workloads, which aligns with the strong 4K performance observed. The 3DMark Steel Nomad DX12 score of 6,567 further corroborates that the GPU is not the weak link in this pairing; rather, the 4K Ultra result of 53 FPS is a consequence of the game's ultra preset being designed for earlier hardware generations.

How This Combo Ranks

The combo of Intel Core Ultra 5 125H and NVIDIA GeForce RTX 4080 ranks 902 out of 2,928 tested combinations in Downfall, placing it in the 69th percentile of all tested systems. That rank is notable because it puts this combo in the upper third of all configurations, yet the individual components rank higher — the CPU sits at the 79th percentile among all processors, and the GPU at the 86th percentile among all graphics cards. The discrepancy between component percentiles and combo rank suggests that Downfall is not fully utilizing the CPU's capabilities, or that the mobile platform introduces bottlenecks that desktop combos do not face.

The CPU's nearest rivals provide context for its performance class. The AMD Ryzen 7 5800 has an average benchmark score of 27,535, which is a -0.1% delta from the Core Ultra 5 125H's average of 27,507. The Intel Core i5-12600K and AMD Ryzen 7 5700X both score 27,578, a -0.3% delta, while the AMD Ryzen 3 PRO 5355G scores 27,382, a +0.5% delta. These near-identical scores mean the 125H performs like a mid-range desktop CPU from the previous generation, despite being a mobile part with a 28 W TDP. In Downfall, however, the combo rank of 902 out of 2,928 implies that many systems with lower-spec CPUs but faster desktop GPUs outrank this mobile pairing.

The GPU's nearest rivals show that the RTX 4080 is at the top of its class. The RTX 4080 SUPER scores 54,209, a mere 0.1% higher, while the AMD Radeon Pro W5700X scores 54,828, a -1.1% delta, and the AMD Radeon RX 6750 GRE 12 GB scores 55,698, a -2.6% delta. These differences are within noise for synthetic benchmarks, meaning the RTX 4080 is effectively performance-equivalent to the SUPER variant in this title. The fact that the combo still only reaches rank 902 suggests that the mobile CPU's thermal and power constraints, not the GPU, are what hold the system back in Downfall's more CPU-sensitive scenarios.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce an average of 287 FPS, which is more than enough for any high-refresh-rate display. Medium settings yield 235 FPS average, with a minimum of 199 FPS and maximum of 270 FPS, showing tight frame pacing. High settings average 192 FPS, while Ultra drops to 120 FPS average. The 1080p results indicate that the CPU can feed the GPU up to 287 FPS, but the Ultra preset at 120 FPS suggests that the game's draw calls and shadow calculations become more demanding, yet still remain well within playable territory.

Moving to 2560x1440, the frame rates remain high but show the expected resolution penalty. Low settings average 205 FPS, which is still exceptionally smooth. Medium settings average 168 FPS, with a minimum of 142 FPS and maximum of 193 FPS. High settings average 137 FPS, and Ultra drops to 86 FPS average. The 1440p Ultra result of 86 FPS is particularly relevant for users with 144 Hz monitors, as it means the system can drive that refresh rate at high but not ultra settings. The minimum frame rate of 142 FPS at Medium settings indicates that even in demanding scenes, the system stays above 140 FPS, providing a consistent experience.

At 3840x2160, the system still maintains playable frame rates across all presets. Low settings average 127 FPS, which is remarkable for 4K and suggests the game is not particularly demanding on older hardware. Medium settings average 104 FPS, with a minimum of 89 FPS and maximum of 120 FPS. High settings average 85 FPS, while Ultra falls to 53 FPS average. The 4K Ultra result of 53 FPS is the only measurement below 60 FPS in the entire dataset, indicating that users targeting 4K 60 FPS should stick to High settings or lower. The Medium preset at 4K, with its 104 FPS average and 89 FPS minimum, offers the best balance for 4K gaming on this combo.

Settings Recommendations

The measured data points to Medium settings as the sweet spot for this combo across all resolutions. At 1080p Medium, the system delivers 235 FPS average with a 199 FPS minimum and 270 FPS maximum, providing a frame rate that exceeds any display refresh rate currently available. At 1440p Medium, the 168 FPS average with a 142 FPS minimum ensures a smooth experience on high-refresh monitors, and even at 4K Medium, the 104 FPS average with an 89 FPS minimum keeps gameplay fluid. The Medium preset consistently outperforms High by roughly 20-25% in average frame rate, while the visual difference in a horror game like Downfall is likely minimal given its 2016 release date.

For users with 60 Hz displays, the High preset at 4K (85 FPS average) or Ultra at 1440p (86 FPS average) offers the best visual quality without sacrificing playability. The Ultra preset at 1080p (120 FPS average) is also viable, but the jump from Medium to Ultra at 4K costs 51 FPS (from 104 to 53), which is a steep price for the highest visual fidelity. Given that Downfall is a horror game where atmosphere matters, the Medium preset's combination of frame rate consistency and visual quality makes it the recommended default, with Low settings reserved for users prioritizing maximum frame rates on 240 Hz displays. The data shows no scenario where Ultra settings provide a playable experience at 4K, so users should either cap settings at High for 4K or accept the 53 FPS average if they insist on maximum quality.
