Downfall

# Downfall Performance Analysis: Intel Core Ultra 9 275HX + NVIDIA GeForce RTX 5090 Mobile

The measured frame rates for this combination reveal a system that is thoroughly GPU-bound at higher resolutions, yet shows surprising headroom at 1080p where the CPU's 24 cores and 5.40 GHz boost clock begin to matter. This pairing of Intel's top-tier Arrow Lake-HX mobile processor with NVIDIA's flagship Blackwell laptop GPU delivers playable performance across all tested configurations, though the scaling patterns expose where each component's influence wanes. The data set includes twelve distinct measurement points spanning three resolutions and four quality presets, offering a comprehensive view of how this flagship mobile duo handles Downfall's horror environments.

Resolution Scaling

The frame rate deltas between 1080p and 4K tell a clear story about system bottlenecking. At Low settings, the average FPS drops from 328 at 1920x1080 to 146 at 3840x2160, a reduction of 182 frames per second (55.5% decrease). This dramatic falloff indicates that the RTX 5090 Mobile's rendering pipeline becomes increasingly saturated as pixel count rises, while the CPU has ample capacity to feed frames at lower resolutions. The 24-core Ultra 9 275HX, with its 2.70 GHz base and 5.40 GHz boost, appears more than capable of keeping up with the GPU's output at 1080p Low, where the 328 FPS figure likely approaches the engine's internal limits.

Moving to High settings, the scaling pattern shifts slightly. The 1920x1080 result of 220 FPS drops to 157 FPS at 2560x1440 (a 28.6% reduction), then further to 98 FPS at 3840x2160 (another 37.6% drop from 1440p). The diminishing returns between 1440p and 4K suggest that the GPU's 24 GB of GDDR7 memory and 896.0 GB/s bandwidth are being taxed heavily by the higher resolution's increased texture and shading demands. Notably, the 4K High result of 98 FPS remains above the 60 FPS threshold, indicating the GPU's 10496 shading units and 112 ROPs provide sufficient raw throughput for this horror title at 4K.

Ultra settings present the most extreme scaling curve. The 138 FPS at 1080p falls to 98 FPS at 1440p (a 29.0% reduction), then plummets to 61 FPS at 4K (a 37.8% drop from 1440p). This pattern suggests that Ultra presets introduce effects that disproportionately impact higher resolutions, likely including volumetric lighting or screen-space reflections that scale with pixel count. The 61 FPS at 4K Ultra sits right at the edge of playability, while the 138 FPS at 1080p Ultra demonstrates that this combination can handle maximum quality when resolution is kept moderate.

The data reveals an interesting inversion: at 1080p, the gap between Low (328 FPS) and Ultra (138 FPS) is 190 FPS, while at 4K, that same gap narrows to 85 FPS (146 vs 61). This compression at higher resolutions confirms that the GPU becomes the limiting factor, masking the performance cost of quality settings. Conversely, at 1080p, the CPU's influence is more apparent—the 24 threads allow the system to maintain high frame rates even when the GPU is less stressed.

Settings Recommendations

For players targeting 60 FPS as a minimum, the 4K Ultra preset delivers 61 FPS on average, making it technically viable but leaving almost no headroom for demanding scenes. The 4K High preset, at 98 FPS, provides a more comfortable margin while still offering substantial visual quality. Given that the jump from High to Ultra at 4K costs 37 FPS (a 37.8% reduction), the High preset appears to be the sweet spot for 4K displays—it maintains frame rates well above refresh-rate thresholds while avoiding the performance cliff of Ultra.

At 2560x1440, all four presets exceed 90 FPS, with High (157 FPS) and Medium (192 FPS) both offering excellent experiences. The Ultra preset at 98 FPS matches the 4K High result, suggesting that 1440p Ultra is equivalent in cost to 4K High on this hardware. For 1440p users, Medium or High provide the best balance—Medium's 192 FPS offers ample headroom for high-refresh-rate monitors, while High's 157 FPS still comfortably exceeds 144 Hz displays. The 234 FPS Low result at 1440p is unnecessarily high for most displays and sacrifices too much visual fidelity.

The 1920x1080 results show this combination is overkill for standard monitors. Even Ultra presets achieve 138 FPS, which exceeds 120 Hz displays, while Medium (269 FPS) and High (220 FPS) push well beyond 240 Hz capabilities. For 1080p players, the choice between High and Ultra depends on refresh rate—those with 144 Hz panels can enable Ultra and still maintain 138 FPS, while 240 Hz users should stick with High to stay above 200 FPS. The Low preset at 328 FPS serves no practical purpose on current display technology.

Considering the full data set, the High preset at 2560x1440 represents the best overall experience—it delivers 157 FPS, which exceeds all common refresh rates, while the 98 FPS 4K High result offers a viable 4K option. The Medium preset at 4K (119 FPS) also warrants consideration, as it provides a 21 FPS improvement over High at the cost of some visual effects, with its minimum FPS of 101 ensuring smooth playback.

How This Combo Ranks

Among the 3,716 tested combinations in the database, this pairing ranks 803rd in Downfall specifically. This places it in the top 21.6% of all tested systems, though the ranking suggests that numerous other configurations—likely including desktop parts and possibly dual-GPU setups—achieve higher frame rates in this title. The percentile position indicates that while this mobile flagship is formidable, it does not dominate Downfall's leaderboard.

The CPU's overall percentile of 94 versus all processors, combined with its average benchmark score of 67,469, positions it slightly below the Intel Xeon w5-3525 (67,673 average, -0.3% delta) and AMD EPYC 4484PX (67,822 average, -0.5% delta). These rival comparisons are based on synthetic benchmarks rather than gaming performance, but they contextualize the Ultra 9 275HX's compute capabilities. The 0.7% advantage over the Intel Xeon 6515P (67,006 average) shows how tightly clustered these high-end processors are in raw throughput.

For the GPU, the RTX 5090 Mobile's 84th percentile ranking places it behind several desktop cards in the aggregate database. Its average benchmark score of 45,152 is nearly identical to the AMD Radeon Pro 5500 XT (45,384, -0.5% delta) and slightly ahead of the NVIDIA GeForce RTX 4070 Ti (44,795, +0.8% delta). However, these comparisons use synthetic workloads that may not reflect Downfall's specific engine characteristics. The 3DMark Steel Nomad DX12 score of 5,871 and Passmark G3D score of 30,034 indicate strong DirectX 12 performance, which aligns with Downfall's modern rendering requirements.

The gap between the 803rd rank in Downfall and the top-20% CPU/GPU percentiles suggests that either the game is particularly sensitive to certain hardware characteristics, or that the mobile platform's power constraints limit sustained performance. The 95 W TDP for the GPU and 55 W for the CPU indicate a combined thermal budget that may throttle during extended sessions, potentially explaining why this combination doesn't rank higher despite its component-level strength.

Measured FPS Breakdown

The complete measured data set reveals consistent scaling across all settings and resolutions:

At 1920x1080, the Low preset achieves 328 FPS average. The Medium preset delivers 269 FPS average with a minimum of 228 FPS and maximum of 309 FPS, showing a 59 FPS drop from Low. High settings produce 220 FPS average, while Ultra drops to 138 FPS average. The progression from Low to Ultra at 1080p shows a 190 FPS total reduction, with each settings tier costing approximately 50-60 FPS at this resolution.

The 2560x1440 results follow a similar pattern with compressed margins. Low settings yield 234 FPS average, Medium delivers 192 FPS (minimum 163, maximum 221), High produces 157 FPS, and Ultra achieves 98 FPS. The total spread from Low to Ultra is 136 FPS, significantly less than the 190 FPS spread at 1080p. The Medium preset's minimum of 163 FPS ensures consistent performance even in demanding scenes.

At 3840x2160, the distribution tightens further. Low settings average 146 FPS, Medium averages 119 FPS (minimum 101, maximum 137), High averages 98 FPS, and Ultra averages 61 FPS. The 85 FPS spread from Low to Ultra at 4K represents less than half the spread seen at 1080p. Notably, the 4K Ultra result of 61 FPS is the only measured configuration below 60 FPS, though it barely clears that threshold.

The Medium preset is the only configuration with complete minimum and maximum data across all three resolutions. The minimum-to-average gaps are 41 FPS at 1080p (228 min vs 269 avg), 29 FPS at 1440p (163 vs 192), and 18 FPS at 4K (101 vs 119). This narrowing variance at higher resolutions further confirms the GPU bottleneck theory—when the GPU is saturated, frame time consistency improves because the CPU has spare capacity to handle spikes.

CPU Role

The Intel Core Ultra 9 275HX brings substantial compute resources to this pairing. With 24 cores and 24 threads operating at a 2.70 GHz base clock and 5.40 GHz boost, this Arrow Lake-HX processor provides the kind of multi-threaded headroom that modern games increasingly exploit. The 36 MB of shared L3 cache and 3 MB L2 cache per core help maintain high memory throughput, while the dual-channel DDR5 support with 102.4 GB/s bandwidth ensures the GPU receives data without stalling.

The CPU's synthetic performance underscores its capabilities. The Cinebench R23 multi-core score of 35,589 and single-core score of 2,204 demonstrate strong both-threaded and single-threaded performance. The Geekbench multi-core score of 20,795 and single-core score of 2,458 further confirm this processor's balanced capabilities. The Passmark multi-thread score of 55,759 and single-thread score of 4,713 indicate that this CPU can handle both heavily threaded workloads and latency-sensitive single-thread tasks.

In Downfall specifically, the CPU's influence is most apparent at 1080p Low settings, where the 328 FPS result suggests the processor is capable of feeding frames faster than the GPU can render them. The 24 threads allow the game's background simulation and physics systems to run concurrently with rendering tasks without creating bottlenecks. However, the 94th percentile ranking versus all CPUs and the tight clustering of nearest rivals (all within 0.7% of the average score) indicate that this processor is not uniquely advantaged for gaming—many workstation and server chips offer comparable raw throughput.

The 3 nm process node and 17,800 million transistors in a 243 mm² die demonstrate Intel's use of TSMC's advanced manufacturing, which contributes to the 55 W TDP. This power envelope allows the CPU to maintain high clocks during gaming sessions without excessive thermal throttling, though the combined 150 W CPU+GPU thermal budget may still limit sustained performance in thin laptop chassis.

GPU Role

The NVIDIA GeForce RTX 5090 Mobile is the dominant force in this pairing, and the benchmark data reflects its considerable capabilities. The GB203 chip, built on TSMC's 5 nm process with 45,600 million transistors in a 378 mm² die, provides 10,496 shading units, 328 TMUs, and 112 ROPs. The 82 RT cores and 328 tensor cores offer dedicated hardware for ray tracing and AI-enhanced features, though Downfall's horror aesthetic may not heavily utilize these capabilities.

The 24 GB of GDDR7 memory on a 256-bit bus delivers 896.0 GB/s of bandwidth, which proves critical at 4K resolutions where texture and geometry data demands are highest. The memory clock of 1750 MHz (28 Gbps effective) allows the GPU to feed its 10496 shading units efficiently. The base clock of 990 MHz and boost clock of 1515 MHz represent the mobile power envelope's constraints—desktop equivalents run at higher frequencies, which partially explains the GPU's 84th percentile ranking.

The GPU's synthetic benchmarks provide context for its Downfall performance. The 3DMark Steel Nomad DX12 score of 5,871 and Passmark G3D score of 30,034 indicate strong DirectX 12 performance, which aligns with the game's modern rendering pipeline. The Geekbench OpenCL score of 201,834 and Vulkan score of 198,405 show balanced compute capabilities across APIs. The Passmark DirectX 11 score of 269 versus DirectX 12 score of 138 suggests the GPU is more optimized for modern APIs.

The nearest rival comparisons reveal interesting positioning. The RTX 5090 Mobile's average benchmark score of 45,152 is nearly identical to the desktop RTX 4070 Ti (44,795, +0.8% delta) and Radeon Pro 5500 XT (45,384, -0.5% delta). This suggests that mobile flagship GPUs now match previous-generation desktop performance, though the 95 W TDP and IGP slot width indicate significant thermal constraints compared to desktop cards with dedicated cooling and power delivery.

In Downfall, the GPU's role becomes increasingly dominant as resolution increases. The 4K Ultra result of 61 FPS shows the GPU operating near its limits, while the 1080p Low result of 328 FPS demonstrates its ability to push extremely high frame rates when not pixel-bound. The 24 GB VRAM capacity ensures that even the most demanding texture packs at 4K Ultra will not exceed memory limits, leaving the 896.0 GB/s bandwidth as the primary constraint at higher resolutions.
