Downfall

# Downfall with Intel Core Ultra 5 125H + NVIDIA GeForce RTX 4090 Mobile

This combo ranks 826th out of 3,716 tested combinations in Downfall, placing it in the top 22% of all tested hardware pairings. That rank is driven primarily by the GPU's strong showing in this horror title, while the CPU contributes enough to avoid bottlenecking at most settings. The measured frame rates across resolutions and presets reveal a system that can handle 4K at high settings comfortably, but the Ultra preset at 4K is the only configuration where the experience drops below 60 FPS. For a 2016 horror game, this pairing delivers far more headroom than the genre typically demands, making it a versatile option for players who want maximum visual fidelity or extremely high refresh rates at lower resolutions.

How This Combo Ranks

The 826th position out of 3,716 tested combos puts this pairing in the 77th percentile of all combinations measured in Downfall. That is a strong result, though not a top-tier one, because the CPU sits below the GPU in relative performance. The Intel Core Ultra 5 125H ranks in the 79th percentile among all CPUs, while the RTX 4090 Mobile ranks in the 84th percentile among all GPUs. The combo's overall rank being lower than both individual component percentiles suggests that Downfall's workload does not scale perfectly with this pairing, or that the mobile platform constraints limit the GPU's full potential.

Looking at the measured data, the gap between this combo and the top-ranked systems is most visible at 4K Ultra, where the average FPS drops to 59. That is the only preset where the system falls below 60 FPS, and it does so by just one frame. At 1440p Ultra, the average jumps to 94 FPS, and at 1080p Ultra it reaches 132 FPS. These numbers indicate that the combo's rank is held back primarily by the 4K Ultra scenario, not by any fundamental weakness in the hardware.

The CPU's nearest rivals provide context for its contribution. The AMD Ryzen 7 5800 scores 27,535 on average, which is 0.1% higher than the Core Ultra 5 125H's 27,507 average benchmark score. The Intel Core i5-12600K and AMD Ryzen 7 5700X both score 27,578, putting them 0.3% ahead. The AMD Ryzen 3 PRO 5355G scores 27,382, which is 0.5% behind. These are all extremely close margins, meaning the Core Ultra 5 125H is competitive with several well-known desktop CPUs from previous generations, despite being a mobile part with a 28 W TDP.

The NVIDIA RTX A6000 scores 44,075, which is 0.9% ahead. These deltas are small, indicating that the RTX 4090 Mobile sits in a performance cluster with professional workstation cards and a newer mobile GPU. In Downfall specifically, the GPU's 16 GB of VRAM and 576.0 GB/s memory bandwidth provide ample resources for the game's textures and effects.

GPU Role

The NVIDIA GeForce RTX 4090 Mobile is the dominant component in this pairing, and its specifications explain why Downfall runs so smoothly at most settings. The GPU uses the AD103 chip on TSMC's 5 nm process, with 45,900 million transistors packed into a 379 mm² die. That transistor density of 121.1M per mm² is among the highest in the mobile GPU space, enabling the 9,728 shading units, 304 texture mapping units, and 112 raster output pipelines to work efficiently.

Clock speeds for the RTX 4090 Mobile are listed at 1,335 MHz base and 1,695 MHz boost. These are relatively modest clocks for a flagship GPU, but the Ada Lovelace architecture's efficiency means the card still delivers 32.98 TFLOPS of FP32 performance. The 76 ray tracing cores and 304 tensor cores provide hardware acceleration for any ray-traced effects in Downfall, though the game's 2016 release date means it likely relies more on traditional rasterization. The pixel rate of 189.8 GPixel/s and texture rate of 515.3 GTexel/s are more than sufficient for a horror game that emphasizes atmosphere over raw geometric complexity.

Memory is a key strength. The 16 GB of GDDR6 VRAM on a 256-bit bus provides 576.0 GB/s of bandwidth. At 4K Ultra, Downfall's highest preset, the GPU maintains 59 FPS average. At 4K High, the average rises to 94 FPS. The 16 GB capacity ensures that texture-heavy scenes at 4K will not exceed VRAM limits, which is particularly important for a game that relies on dark, detailed environments to build tension. The memory clock runs at 2,250 MHz, or 18 Gbps effective, which is a high speed for GDDR6.

The GPU's average benchmark score of 43,667 places it in the 84th percentile of all GPUs. Its nearest rival, the RTX A6000, scores 44,075, which is 0.9% higher. The Quadro M6000 scores 43,301, which is 0.8% lower. These margins are small, but in Downfall the RTX 4090 Mobile's performance is clearly sufficient for high-refresh-rate gaming at 1440p and above. The measured FPS at 1440p High is 150, and at 1080p High it reaches 211. Even at 4K High, the 94 FPS average is well above the 60 FPS target that most players consider the baseline for smooth gameplay.

Settings Recommendations

For 4K displays, the best experience is Medium settings. The measured data shows 114 FPS average, with a minimum of 97 FPS and a maximum of 131 FPS. This preset keeps the frame rate well above 60 FPS at all times, even in the most demanding scenes. High settings at 4K drop the average to 94 FPS, which is still playable, but the lack of minimum FPS data for High makes Medium the safer choice for consistent performance. Ultra at 4K averages 59 FPS, which is technically playable but leaves no margin for frame drops, and the minimum FPS is not recorded for this preset.

For 1440p, High settings at 150 FPS average is the standout choice. This provides a smooth experience on 144 Hz monitors, and the visual quality is high. Medium settings at 1440p deliver 184 FPS average with a minimum of 156 FPS, which is even more headroom for competitive play or for players who prefer maximum smoothness. Low settings at 1440p reach 224 FPS, which is useful for esports-style play, but the visual compromise is significant for a horror game that relies on atmosphere. Ultra at 1440p averages 94 FPS, which is identical to 4K High, making it a reasonable choice for players who want maximum quality at 1440p.

For 1080p, the recommendation depends on the monitor's refresh rate. For 240 Hz monitors, Medium settings at 257 FPS average (minimum 218 FPS) or Low at 314 FPS are the best options. For 144 Hz or 165 Hz monitors, High settings at 211 FPS average provide excellent quality with plenty of headroom. Ultra at 1080p averages 132 FPS, which is above 120 Hz and suitable for most high-refresh displays, though the visual difference between High and Ultra may not justify the 79 FPS drop in average frame rate.

The general pattern across all resolutions is that Medium provides the best balance of visual fidelity and performance, while High offers a modest quality increase at a noticeable FPS cost. Ultra is the most demanding preset and only recommended for 1080p or 1440p, where the frame rates remain above 90 FPS.

Measured FPS Breakdown

At 3840x2160 (4K), the combo delivers a wide range of performance depending on settings. Low settings produce 140 FPS average, which is remarkable for 4K and indicates the game is not particularly demanding at lower presets. Medium settings yield 114 FPS average, with a minimum of 97 FPS and a maximum of 131 FPS, providing consistent performance above the 60 FPS threshold. High settings drop to 94 FPS average, which is still smooth but represents a 20 FPS reduction from Medium. Ultra settings at 4K average 59 FPS, which is just below the 60 FPS standard and the only measured configuration that fails to reach that target.

At 2560x1440 (1440p), the performance scales up significantly. Low settings reach 224 FPS average, which is excellent for high-refresh-rate gaming. Medium settings produce 184 FPS average, with a minimum of 156 FPS and a maximum of 211 FPS, ensuring no drops below the 144 Hz threshold. High settings average 150 FPS, which is still above 144 Hz and provides a strong balance of quality and speed. Ultra settings at 1440p average 94 FPS, which matches the 4K High result and demonstrates that Ultra is roughly equivalent to a 4K High workload.

At 1920x1080 (1080p), the combo shows its full potential. Low settings reach 314 FPS average, which is extremely high and suitable for 300 Hz monitors if such displays are available. Medium settings produce 257 FPS average, with a minimum of 218 FPS and a maximum of 295 FPS, providing consistent performance above 240 Hz. High settings average 211 FPS, which is above 200 FPS and ideal for 240 Hz displays. Ultra settings at 1080p average 132 FPS, which is above 120 Hz and provides a console-beating experience with maximum visual quality.

The scaling between resolutions follows a predictable pattern. Moving from 1080p to 1440p reduces frame rates by approximately 30-35% across most settings. Moving from 1440p to 4K reduces frame rates by approximately 40-45%. The Medium preset consistently shows the tightest minimum-to-maximum FPS range, indicating that this preset produces the most stable frame pacing. The Low preset shows the highest averages but lacks minimum FPS data, so its consistency cannot be verified from the measured values.

CPU Role

The Intel Core Ultra 5 125H is a 14-core, 18-thread mobile processor based on the Meteor Lake architecture, built on Intel's 7 nm process. It has a base clock of 3.60 GHz and a boost clock of 4.50 GHz, with a TDP of 28 W. The cache hierarchy includes 112 KB of L1 per core, 2 MB of L2 per core, and 18 MB of shared L3 cache. Memory support is DDR5 with dual-channel configuration and 89.6 GB/s of bandwidth. The CPU integrates Arc Xe-LPG 96EU graphics, though the discrete RTX 4090 Mobile handles all rendering in Downfall.

In Downfall, the CPU's role is to feed the GPU with draw calls and game logic. The measured frame rates at 1080p Low (314 FPS average) suggest that the CPU can handle very high frame rates without becoming a bottleneck. The 18 threads provide ample parallelism for the game's horror-themed environments, which often feature complex lighting and shadow calculations. The boost clock of 4.50 GHz is competitive for single-threaded performance, as evidenced by the Cinebench R23 single-core score of 1,647.5 and PassMark single-thread score of 3,399.

The CPU's overall benchmark results show a balanced profile. The Cinebench R23 multi-core score of 12,804.5 and PassMark multi-thread score of 21,100 indicate solid multi-threaded performance. The PassMark integer math score of 69,986 and floating-point math score of 51,670 show that the CPU handles both types of workloads effectively. The data compression score of 236,209 and encryption score of 14,251 are less relevant for gaming but indicate general processing capability.

Comparing the Core Ultra 5 125H to its nearest rivals, the performance differences are negligible. The AMD Ryzen 7 5800 is 0.1% faster, the Intel Core i5-12600K and AMD Ryzen 7 5700X are each 0.3% faster, and the AMD Ryzen 3 PRO 5355G is 0.5% slower. These margins are within measurement noise, meaning the Core Ultra 5 125H performs equivalently to these desktop CPUs in synthetic benchmarks. In Downfall specifically, the CPU's 79th percentile rank among all CPUs ensures it does not limit the GPU's performance in most scenarios.

The CPU's memory bandwidth of 89.6 GB/s and dual-channel DDR5 support are adequate for the game's data streaming needs. The 18 MB of shared L3 cache helps keep frequently accessed data close to the cores, reducing latency. The 7 nm process node and 28 W TDP mean the CPU generates modest heat, which is beneficial in a mobile form factor where thermal headroom is limited. However, the CPU's performance in this combo is secondary to the GPU, as Downfall's frame rates scale more with GPU settings than with CPU capabilities, as evidenced by the significant FPS differences between Low and Ultra presets at the same resolution.
