Downfall

Resolution Scaling

The measured frames per second across the three tested resolutions reveal a classic pattern of GPU-bound scaling, with the Intel Core Ultra 5 235 and NVIDIA GeForce RTX 3080 combination demonstrating diminishing returns as pixel count increases. At 1080p with Low settings, the combo delivers 299 FPS average, which drops to 214 FPS at 1440p and further to 133 FPS at 4K. This represents a 55.5% reduction from 1080p to 4K at Low settings, indicating that the GPU's rendering load scales almost linearly with pixel count when the CPU has ample headroom.

The High settings preset shows a similar trajectory: 201 FPS at 1080p, 143 FPS at 1440p, and 89 FPS at 4K. The percentage drops between resolutions are consistent—roughly 29% from 1080p to 1440p and 38% from 1440p to 4K—which suggests the system is not being bottlenecked by the processor at any point in this range. Medium settings follow suit with 245 FPS, 175 FPS, and 109 FPS across the three resolutions, respectively, maintaining the same proportional scaling pattern.

Ultra settings, however, introduce a steeper cliff. At 4K Ultra, the average FPS plunges to 56, which is less than half of the 4K High result. This nonlinear drop indicates that the Ultra preset likely enables effects that disproportionately tax the RTX 3080's memory bandwidth or shading resources. The 1440p Ultra result of 90 FPS and 1080p Ultra result of 125 FPS show less severe relative penalties, but the 4K Ultra figure stands out as the most demanding configuration tested.

The scaling behavior points to the GPU as the limiting component across all resolution and settings combinations. The CPU, with its 14 cores and 14 threads, has sufficient compute headroom to feed the graphics card even at 1080p Low where the frame rate approaches 300 FPS. The data shows no evidence of CPU saturation, as the frame rate differences between resolution tiers remain proportional to the pixel count changes rather than flattening out at higher resolutions.

How This Combo Ranks

Within the database of 2,928 tested combinations for Downfall, this pairing of the Intel Core Ultra 5 235 with the NVIDIA GeForce RTX 3080 achieves a combo rank of 776. This places the configuration in the upper quartile of all tested systems, roughly the 73.5th percentile. The rank reflects the combined capability of both components working together in this specific horror title, which tends to favor higher single-thread performance and substantial GPU memory bandwidth.

The CPU alone sits at the 89th percentile among all processors, with an average benchmark score of 46,062. Its nearest rivals include the AMD Ryzen AI 9 HX 375 at 46,030 (0.1% higher), the Intel Core i9-13900HX at 46,098 (0.1% lower), and the AMD EPYC 4364P at 45,970 (0.2% higher). These margins are negligible, indicating the Ultra 5 235 performs essentially on par with a broad cluster of high-end desktop and mobile processors in synthetic workloads.

The GPU, by contrast, ranks at the 68th percentile among all graphics cards, with an average benchmark score of 23,172. Its nearest rivals—the NVIDIA P106-100, AMD Radeon Pro Vega 16, AMD Radeon RX 6600M, and AMD Radeon R9 M290X—all sit within 0.4% of the RTX 3080's score, which is a surprisingly tight grouping given the architectural differences between these parts. This suggests the RTX 3080's synthetic benchmark performance is well understood and consistent, even though its real-world gaming results in Downfall may diverge from those synthetic numbers.

The gap between the CPU's 89th percentile and the GPU's 68th percentile explains why the combo ranks at 776 rather than higher. The graphics card is the weaker link in this pairing, and the overall rank reflects that constraint. For a horror game like Downfall, where atmospheric lighting and shadow effects often stress GPU resources, this imbalance is more consequential than in lighter titles.

CPU Role

The Intel Core Ultra 5 235 brings 14 cores and 14 threads to this configuration, running at a base clock of 3.40 GHz and a boost clock of 5.00 GHz. This processor is built on the Arrow Lake architecture using a 3 nm process from TSMC, with 17,800 million transistors on a 243 mm² die. The cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache, which provides substantial on-die storage for game data.

In Downfall, the CPU's role appears to be secondary to the GPU, given the measured frame rates. At 1080p Low, the system achieves 299 FPS, which would require the processor to maintain high per-thread throughput to avoid becoming a bottleneck. The single-core performance, as reflected in Cinebench R23 at 2,085 points, is competitive with other high-end desktop parts, and the boost clock of 5.00 GHz ensures that the game's main simulation thread has access to rapid execution.

The processor's multi-threaded capabilities are also relevant, as Downfall may offload some tasks to additional cores. The Cinebench R23 multi-core score of 14,769 and PassMark multi-thread score of 37,816 indicate strong parallel performance, though the game's scaling with thread count is not directly measurable from the provided data. The 14 threads (one per core, no hyperthreading) are sufficient for most gaming scenarios, and the 65 W TDP suggests the CPU can sustain boost clocks without excessive thermal throttling in a typical desktop chassis.

Memory bandwidth of 102.4 GB/s over dual-channel DDR5 provides adequate data throughput for feeding the GPU at high frame rates. The PCIe Gen 5 interface with 20 CPU lanes offers ample bandwidth for the RTX 3080, though the GPU itself uses PCIe 4.0 x16, which is backward compatible. The integrated Arc Xe-LPG Graphics 24EU is present but irrelevant for gaming when a discrete GPU is installed.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings presets, providing a comprehensive view of performance. At 1920x1080, the Low preset delivers an average of 299 FPS, which is the highest recorded figure in the entire dataset. Medium at 1080p averages 245 FPS with a minimum of 208 FPS and maximum of 282 FPS, showing a tight frame time distribution. High at 1080p averages 201 FPS, while Ultra at 1080p averages 125 FPS—a 58% reduction from Low, highlighting the significant cost of Ultra effects.

Moving to 2560x1440, the Low preset averages 214 FPS, Medium averages 175 FPS (min 149, max 201), High averages 143 FPS, and Ultra averages 90 FPS. The frame time variance at Medium settings (149-201 FPS) spans 52 FPS, which is proportionally larger than the 74 FPS spread at 1080p Medium (208-282 FPS), suggesting that 1440p introduces more variable rendering workloads.

At 3840x2160, the Low preset averages 133 FPS, Medium averages 109 FPS (min 92, max 125), High averages 89 FPS, and Ultra averages 56 FPS. The 4K Medium frame time range of 92-125 FPS represents a 33 FPS spread, which is tighter in relative terms than the 1440p Medium spread. The Ultra preset at 4K is the only configuration that drops below 60 FPS, making it the sole result that might be considered suboptimal for smooth gameplay on a standard 60 Hz display.

Across all resolutions, the Low-to-Ultra scaling shows consistent multiplicative relationships. At 1080p, Ultra achieves 41.8% of Low's frame rate. At 1440p, Ultra achieves 42.1% of Low. At 4K, Ultra achieves 42.1% of Low. This consistency suggests the settings presets scale similarly regardless of resolution, with the absolute frame rates determined by pixel count.

Settings Recommendations

For players prioritizing smooth gameplay at high refresh rates, the 1080p Medium preset offers an excellent balance with 245 FPS average and a minimum of 208 FPS, ensuring no drops below 200 FPS in the measured data. The 1440p Medium preset at 175 FPS average (min 149 FPS) is similarly robust, making it a strong choice for users with 144 Hz displays at that resolution.

At 4K, the High preset at 89 FPS average is the most balanced option, providing a significant visual upgrade over Medium (109 FPS) while maintaining a comfortable margin above 60 FPS. The 4K Ultra preset at 56 FPS average falls below the 60 FPS threshold, which may be acceptable for players who prioritize visual fidelity over frame rate consistency, but the measured minimum FPS is not available for this configuration, leaving uncertainty about worst-case frame times.

The Low presets, while delivering the highest frame rates (299 FPS at 1080p, 214 FPS at 1440p, 133 FPS at 4K), sacrifice the visual quality that a horror game like Downfall relies on for atmosphere. The Medium presets provide the best compromise between visual fidelity and performance across all three resolutions, with the 1440p Medium result of 175 FPS being particularly noteworthy for its combination of resolution and speed.

For users with variable refresh rate monitors, the Medium preset at each resolution offers the widest measured frame time headroom. The 1080p Medium range (208-282 FPS) and 1440p Medium range (149-201 FPS) both show substantial headroom above their respective minimums, allowing for smooth adaptation to scene complexity. The 4K Medium range (92-125 FPS) is tighter but still provides a 33 FPS window for VRR operation.

GPU Role

The NVIDIA GeForce RTX 3080 is the dominant factor in this combo's gaming performance, equipped with 10 GB of GDDR6X memory on a 320-bit bus, delivering 760.3 GB/s of bandwidth. The GA102 chip, built on Samsung's 8 nm process, contains 28,300 million transistors across a 628 mm² die. Its 8,704 shading units, 272 TMUs, and 96 ROPs handle the pixel and texture workloads in Downfall, while 68 RT cores and 272 tensor cores provide hardware acceleration for ray-traced effects and DLSS if enabled.

The GPU's clock behavior—1440 MHz base and 1710 MHz boost—combined with the 320 W TDP, suggests it can sustain high performance under sustained gaming loads. The measured FPS data at 4K Ultra (56 FPS average) indicates that the card's 10 GB frame buffer and 760.3 GB/s bandwidth are sufficient for this game's Ultra settings at 4K, though the result is marginal for smooth gameplay.

The RTX 3080's synthetic performance, with a 3DMark Steel Nomad DX12 score of 4,407 and PassMark G3D score of 25,086, places it at the 68th percentile among all GPUs. Its FP32 throughput of 29.77 TFLOPS and texture rate of 465.1 GTexel/s provide the raw compute necessary for the measured frame rates. The pixel rate of 164.2 GPixel/s is particularly relevant for a horror game that may employ volumetric effects and heavy post-processing.

The GPU's 68 RT cores support ray-traced lighting, which is common in horror titles for dynamic shadows and reflections. However, the measured data does not specify whether ray tracing is enabled in these presets, so the impact of RT cores on the observed frame rates cannot be isolated. The 10 GB VRAM capacity is adequate for 4K textures in Downfall, as evidenced by the playable frame rates at 4K High, though the 4K Ultra result suggests the memory subsystem is taxed at the highest settings.
