Downfall

Downfall, the 2016 horror title, presents an interesting case study in system scaling when paired with the Intel Core Ultra 5 125H and the NVIDIA GeForce RTX 4090. This combination, ranked 595th out of 2928 tested combos, demonstrates behavior that is heavily influenced by the game's age and the specific workload it places on modern hardware. The data shows a clear narrative: the GPU is rarely the limiting factor, and the experience is instead shaped by how the game engine interacts with the CPU and the graphics settings applied.

Resolution Scaling

The performance drop from 1080p to 4K is significant but not uniform across all settings, revealing where the bottleneck lies. At the Low preset, the average frame rate falls from 314 FPS at 1920x1080 to 140 FPS at 3840x2160. That is a 55.4% reduction in frames, which is a substantial hit. However, the fact that the 1080p score is over 300 FPS suggests the CPU is the primary constraint at that resolution, as the GPU is not being pushed hard enough to reach its maximum potential.

Moving to the High preset, the scaling is more linear. The average drops from 211 FPS at 1080p to 150 FPS at 1440p, and finally to 94 FPS at 4K. This pattern indicates a more balanced workload where both the CPU and GPU are contributing to the frame rate. The transition from 1440p to 4K at High settings results in a 37.3% performance loss, which is a typical cost for the increase in pixel count. This suggests that at High settings, the RTX 4090 is starting to become more of a limiting factor, though still not fully saturated.

The Ultra preset shows the most dramatic scaling. At 1080p, the combo achieves 132 FPS, which drops to 94 FPS at 1440p and then plummets to 59 FPS at 4K. The 4K Ultra result is the only measurable average below 60 FPS in the entire dataset. This steep decline, particularly the 55.3% drop from 1440p to 4K, points to a very heavy GPU workload that overwhelms the card's capabilities at this resolution. It is clear that Ultra settings at 4K are not a viable target for a smooth experience with this hardware.

The Medium preset offers a middle ground, with frame rates of 257 FPS at 1080p, 184 FPS at 1440p, and 114 FPS at 4K. The scaling from 1080p to 4K here is a 55.6% drop, which is nearly identical to the Low preset's percentage loss. This consistency suggests that at Medium and Low settings, the CPU is the primary limiting factor at lower resolutions, and the GPU only becomes the main constraint when the resolution increases enough to add sufficient pixel shading work.

GPU Role

The NVIDIA GeForce RTX 4090 is a monstrous piece of silicon, but the data suggests it is often waiting for instructions in this game. The GPU's specification sheet lists a massive 24 GB of GDDR6X memory on a 384-bit bus with 1.01 TB/s of bandwidth, which is far more than a 2016 horror title should require. The card's 82.58 TFLOPS of FP32 performance and 1,290.2 GTexel/s texture rate are also extreme for this workload. The benchmark results indicate that the GPU is not the bottleneck at 1080p, where the CPU's limits are reached first.

The RTX 4090's role becomes more pronounced as the resolution increases. The card's boost clock of 2520 MHz and base clock of 2235 MHz are high, but the game doesn't seem to push the card into a state where these clocks are the deciding factor. Instead, the data shows that the GPU's raw throughput is sufficient to handle everything except the most demanding settings at 4K. The VRAM capacity is never a concern, as even the highest settings in a game from this era will not come close to exhausting 24 GB.

The GPU's benchmark scores put it in the 88th percentile of all GPUs, and its average benchmark score of 60347 places it in the same league as the Intel Arc Pro A60 and AMD Radeon Pro Vega 48. However, these rivals are not gaming-focused cards, which highlights that the RTX 4090 is primarily a compute and high-resolution gaming monster. In Downfall, the GPU's performance is only truly tested at the 4K Ultra preset, where it produces 59 FPS. This is a surprisingly low result for a card of this caliber, indicating that the game's Ultra settings may have inefficient or exaggerated effects that do not scale well with modern architecture.

How This Combo Ranks

The combo's rank of 595 out of 2928 tested combinations places it in the top 20.3% of all systems tested. This is a strong showing, but not a top-tier result, which is surprising given the components involved. The ranking suggests that while the RTX 4090 is a top-tier GPU, the Intel Core Ultra 5 125H may be holding the system back in certain scenarios. The CPU's average benchmark score of 27507 puts it in the 79th percentile of all CPUs, and it is a near-exact match for the AMD Ryzen 7 5800 and Intel Core i5-12600K, with a deltaPct of -0.1% and -0.3% respectively.

This performance parity with mid-range desktop CPUs from a previous generation indicates that the mobile Ultra 5 125H, despite its 14 cores and 18 threads, is not able to feed the RTX 4090 adequately in all situations. The combo's rank is likely dragged down by the 1080p and 1440p results, where the CPU's limits are exposed. At 4K, the rank might be higher because the GPU becomes the bottleneck, allowing the CPU to catch up. The data shows that the system's overall standing is a compromise between a very strong GPU and a competent, but not flagship, mobile processor.

Settings Recommendations

Based on the measured FPS rows, the optimal balance of visual quality and performance is achieved at the High preset. At 1920x1080, High yields 211 FPS, which is more than enough for any display. At 2560x1440, High produces 150 FPS, which is still exceptionally smooth and provides a significant visual upgrade over Medium. Even at 3840x2160, High maintains an average of 94 FPS, which is well above the 60 FPS threshold for a playable experience. High offers a 65% performance increase over Ultra at 4K while likely providing a nearly identical visual experience.

The Medium preset is a solid fallback if you are using a 4K display and want to ensure maximum frame rates. The data shows 114 FPS at 4K on Medium, which is a 20.3% improvement over High. However, the visual difference between High and Medium in a horror game with dark environments may be more noticeable than the frame rate suggests. Low settings are generally not recommended, as the 314 FPS at 1080p and 224 FPS at 1440p are wasted on most monitors, and the visual downgrade is likely severe. Ultra should be avoided, especially at 4K, where the 59 FPS average is below the standard for a smooth experience.

FAQ

Q: What is the best resolution for this combo to play Downfall at?

A: The data indicates that 2560x1440 on the High preset is the sweet spot, delivering 150 FPS. This provides a high level of detail with a frame rate that is more than double the 4K Ultra result.

Q: Can this system handle 4K gaming in Downfall?

A: Yes, but with caveats. At 4K High, the average FPS is 94, which is playable. However, at 4K Ultra, the average drops to 59 FPS, which is borderline for smooth gameplay.

Q: How does the CPU affect performance in this game?

A: The Intel Core Ultra 5 125H, with its 14 cores and 18 threads, appears to be the limiting factor at lower resolutions. The 1080p Low preset yields 314 FPS, which suggests the CPU is maxed out, preventing the GPU from pushing even higher frame rates.

Q: Is the RTX 4090's 24 GB of VRAM necessary for this game?

A: No. Downfall is from 2016 and will not utilize that much memory. The VRAM capacity is irrelevant to the measured performance, which is instead governed by the GPU's compute capabilities and the CPU's speed.

Q: What is the difference in performance between the Low and Ultra presets?

A: At 1080p, the difference is 314 FPS on Low versus 132 FPS on Ultra, a 58% reduction. At 4K, the difference is 140 FPS on Low versus 59 FPS on Ultra, a 57.9% reduction. The Ultra preset consistently costs roughly 58% of the frame rate compared to Low.

Q: How does this combo compare to other CPUs in the database?

A: The Intel Core Ultra 5 125H has an average benchmark score of 27507, making it statistically identical to the AMD Ryzen 7 5800 and Intel Core i5-12600K, with a deltaPct of -0.1% and -0.3% respectively.

CPU Role

The Intel Core Ultra 5 125H is a mobile processor with a base clock of 3.60 GHz and a boost clock of 4.50 GHz. It features 14 cores and 18 threads, which is a hybrid design typical of modern mobile chips. However, its performance in Downfall is defined less by its multi-core capabilities and more by its single-thread performance, which is a common trait for games. The CPU's Cinebench R23 single-core score is 1647.5, and its multi-core score is 12804.5. In a game like Downfall, the single-core score is often more indicative of gaming performance.

The CPU's passmark single-thread score of 3399 places it in a competitive position, but the data suggests it is still a bottleneck. The benchmark results show that at 1080p Low, the system hits 314 FPS. This is a high number, but it is likely capped by the CPU's ability to process the game's logic and draw calls. The CPU's percentile rank of 79 against all CPUs and its near-identical performance to the AMD Ryzen 7 5800 (deltaPct -0.1%) and Intel Core i5-12600K (deltaPct -0.3%) confirm that it is a solid mid-range performer, not a top-tier gaming chip.

The 18 MB of shared L3 cache is adequate, but the 28W TDP is a clear indicator of its mobile, power-efficient design. This low power envelope means it cannot sustain the high clocks that a desktop processor with a higher TDP might achieve. In Downfall, this translates to a scenario where the CPU cannot always keep up with the RTX 4090's ability to render frames, particularly at lower resolutions where the GPU is not the limiting factor. The CPU's performance is a bottleneck, but a mild one, as the frame rates are still very high in absolute terms.

Measured FPS Breakdown

The complete dataset provides a full picture of the system's capabilities. At 1920x1080, the Low preset achieves 314 FPS, Medium hits 257 FPS with a minimum of 218 and a maximum of 295, High reaches 211 FPS, and Ultra drops to 132 FPS. The spread from Low to Ultra is 182 FPS, demonstrating a massive performance range based on settings.

At 2560x1440, the results are: Low at 224 FPS, Medium at 184 FPS with a minimum of 156 and a maximum of 211, High at 150 FPS, and Ultra at 94 FPS. The performance gap between Low and Ultra here is 130 FPS. The Medium preset shows a tighter variance between its min and max frames, suggesting a more consistent experience than the 1080p result.

At 3840x2160, the numbers are: Low at 140 FPS, Medium at 114 FPS with a minimum of 97 and a maximum of 131, High at 94 FPS, and Ultra at 59 FPS. This is the only resolution where the Ultra preset falls below 60 FPS. The data shows a clear and consistent pattern: each increase in resolution or settings tier results in a predictable decrease in frame rate. The Medium preset is the only one that reports min and max FPS values, and those values show a spread of 34 FPS at 1080p, 55 FPS at 1440p, and 34 FPS at 4K, indicating that the game's frame time variance is moderate at this setting. The lack of min/max data for other presets limits a deeper analysis of frame pacing, but the averages provide a reliable basis for evaluating performance.
