# Downfall Performance Analysis: Intel Core Ultra 5 235HX + NVIDIA GeForce RTX 4080 Mobile

Downfall, the 2016 horror title, shows remarkable scalability across resolutions and settings with this mobile flagship pairing. The measured data reveals a system that comfortably handles 4K gaming at high framerates, yet the performance curve exposes interesting bottlenecks and optimization opportunities. This analysis examines how the Intel Core Ultra 5 235HX and NVIDIA GeForce RTX 4080 Mobile interact across twelve distinct benchmark configurations, offering insights into where the hardware excels and where diminishing returns appear.

Resolution Scaling

The FPS progression from 1080p to 4K tells a compelling story about system balance. At 1920x1080 with Low settings, the combo produces 287 FPS, which drops to 205 FPS at 2560x1440 and further to 127 FPS at 3840x2160. This represents a 55.7% reduction from 1080p to 1440p, and a 55.8% reduction from 1440p to 4K. The nearly identical percentage drops suggest a consistent scaling pattern dominated by pixel count rather than any sudden architectural limitation.

High settings reveal a similar trend with different magnitudes. The 1080p High result of 192 FPS falls to 137 FPS at 1440p (a 28.6% decrease) and then to 85 FPS at 4K (a 38.0% decrease from 1440p). The larger relative drop at 4K under High settings compared to Low settings indicates that the RTX 4080 Mobile's 12 GB GDDR6 memory and 432.0 GB/s bandwidth begin to feel pressure as both resolution and quality demands increase simultaneously.

Ultra settings present the most dramatic scaling curve. The 120 FPS achieved at 1080p Ultra drops to 86 FPS at 1440p (28.3% decrease) and plummets to 53 FPS at 4K (38.4% decrease from 1440p). The 4K Ultra result sits just barely above playable thresholds for many users, suggesting that this configuration pushes the hardware to its practical limits. The data indicates that at 4K Ultra, the GPU is the clear limiting component, with the 53 FPS average representing a 55.8% reduction from the 1080p Ultra baseline.

The scaling pattern across all settings shows a consistent story: the RTX 4080 Mobile maintains strong performance through 1440p, but 4K Ultra demands more than the 110 W TDP GPU can consistently deliver. The 24.72 TFLOPS FP32 compute and 133.2 GPixel/s pixel rate provide ample headroom at lower resolutions, but the 192-bit memory bus and 432.0 GB/s bandwidth become increasingly strained as pixel throughput requirements escalate.

GPU Role

The NVIDIA GeForce RTX 4080 Mobile serves as the primary performance driver in this pairing, and its characteristics directly explain the measured results. The GPU's 7424 shading units operating at a boost clock of 1665 MHz deliver substantial raw compute power, evidenced by the 287 FPS Low-settings result at 1080p. This figure represents the ceiling of what the memory subsystem and rendering pipeline can sustain when graphical complexity is minimal.

The 12 GB GDDR6 memory running at 2250 MHz (18 Gbps effective) across a 192-bit bus provides 432.0 GB/s of bandwidth. This configuration proves sufficient for most scenarios in Downfall, but the 4K Ultra result of 53 FPS suggests the memory bandwidth becomes a limiting factor when texture loads and shader complexity peak simultaneously. The 104 FPS Medium result at 4K with an 89 FPS minimum and 120 FPS maximum shows the GPU can maintain decent framerates when settings are moderated, but the 51 FPS gap between 4K Medium and 4K Ultra (104 to 53) indicates a sharp cliff in performance scaling.

The GPU's Ada Lovelace architecture, built on TSMC's 5 nm process with 35,800 million transistors, delivers efficiency that allows these high framerates within a 110 W power envelope. The 58 RT cores and 232 tensor cores contribute to the DirectX 12 Ultimate feature set, though Downfall's 2016 release likely doesn't heavily utilize ray tracing or DLSS features. The 24.72 TFLOPS FP16 and FP32 performance (1:1 ratio) suggests compute-heavy workloads aren't a bottleneck, which explains why the GPU maintains strong performance in less demanding settings.

The PassMark G3D score of 24926 places this GPU in the 81st percentile of all GPUs, with nearest rivals including the NVIDIA GeForce RTX 5080 Mobile (deltaPct -0.6) and RTX 4070 (deltaPct 1.3). This close grouping indicates the RTX 4080 Mobile sits at a performance tier where minor architectural differences create small deltas. The 432.0 GB/s bandwidth and 80 ROPs provide the memory throughput and pixel output capacity needed for high-resolution gaming, though the 4K Ultra results demonstrate that raw specifications don't guarantee unlimited headroom.

FAQ

A: At High settings, 4K produces 85 FPS, which is playable. Medium settings yield 104 FPS with a 89 FPS minimum. Ultra settings drop to 53 FPS, which may be acceptable for some users but represents the edge of viability. The data shows 4K is possible with settings compromises.

Q: Why does the GPU performance ranking seem low relative to its FPS results?

A: The RTX 4080 Mobile ranks in the 81st percentile of all GPUs with an average benchmark score of 38135, yet delivers 287 FPS at 1080p Low. This discrepancy reflects that Downfall's rendering demands differ from synthetic benchmarks, and the game appears optimized for the GPU's architecture.

Measured FPS Breakdown

At 1920x1080, the lowest resolution tested, the RTX 4080 Mobile delivers exceptional performance across all settings. Low settings produce 287 FPS average, representing the maximum throughput measured in this dataset. Medium settings reduce this to 235 FPS with a minimum of 199 FPS and maximum of 270 FPS, showing tight frametime consistency. High settings yield 192 FPS, while Ultra drops to 120 FPS. The 1080p results demonstrate a clear linear scaling pattern: each step from Low to Medium reduces performance by 18.1%, Medium to High by 18.3%, and High to Ultra by 37.5%. The larger drop to Ultra suggests specific rendering features that disproportionately impact the GPU.

Moving to 2560x1440, the performance hierarchy remains consistent but the margins compress. Low settings produce 205 FPS, which is 71.4% of the 1080p Low result. Medium achieves 168 FPS with a 142 FPS minimum and 193 FPS maximum, representing 71.5% of the 1080p Medium figure. High settings deliver 137 FPS (71.4% of 1080p High), and Ultra yields 86 FPS (71.7% of 1080p Ultra). This uniform ~71.4% scaling factor across all settings at 1440p indicates that resolution alone, not settings complexity, drives the performance reduction at this tier.

At 3840x2160, the scaling pattern shifts. Low settings produce 127 FPS, which is 44.3% of the 1080p Low result. Medium achieves 104 FPS (44.3% of 1080p Medium) with 89 FPS minimum and 120 FPS maximum. High settings deliver 85 FPS (44.3% of 1080p High), and Ultra drops to 53 FPS (44.2% of 1080p Ultra). The remarkably consistent 44.3% scaling factor across all settings at 4K reinforces that pixel count dictates performance at this resolution, regardless of quality level. However, the absolute differences matter: the 51 FPS gap between 4K Medium and Ultra (104 vs 53) represents a 49% performance penalty that makes Ultra settings impractical at 4K.

The Medium settings rows provide the only min/max data in the dataset, revealing frame pacing characteristics. At 1080p Medium, the 199-270 FPS range spans 71 FPS, indicating some variance but generally smooth delivery. At 1440p Medium, the 142-193 FPS range spans 51 FPS, showing tighter consistency. The 4K Medium range of 89-120 FPS spans just 31 FPS, suggesting that at higher resolutions, the GPU operates closer to its limits and produces more stable frametimes.

Settings Recommendations

The measured data supports a clear recommendation hierarchy based on resolution targets. At 1920x1080, Ultra settings at 120 FPS represent the optimal choice for users prioritizing visual quality without sacrificing smoothness. The 120 FPS average exceeds the 60 FPS threshold by 100%, providing ample headroom for demanding scenes. Users with high-refresh-rate displays might prefer High settings at 192 FPS, which maintains excellent visual fidelity while nearly doubling the framerate. The 287 FPS Low result is unnecessary for most scenarios, though it demonstrates the hardware's ceiling.

For 2560x1440 gaming, Ultra settings at 86 FPS offer the best balance of visual fidelity and performance. The 86 FPS average remains comfortably above 60 FPS, and the 205 FPS Low result confirms the GPU has significant headroom. High settings at 137 FPS provide better motion clarity for competitive play, while Medium at 168 FPS sits between these options. The data suggests that 1440p Ultra is the sweet spot for this hardware, delivering the full visual experience without compromising playability.

At 3840x2160, settings management becomes critical. Ultra at 53 FPS falls below the 60 FPS standard and may cause noticeable stuttering in a horror title where atmosphere depends on smooth motion. High settings at 85 FPS provide the best experience, offering a 60.4% improvement over Ultra while maintaining most visual enhancements. Medium at 104 FPS maximizes framerate for users with 100Hz+ displays, though the 89 FPS minimum approaches the edge of comfort. Low at 127 FPS is overly conservative for 4K, sacrificing visual quality that the GPU can handle at higher settings.

The data indicates that High settings should be the default recommendation at all resolutions, as it consistently delivers framerates 60% or more above the minimum playable threshold while preserving the game's intended visual presentation. Users with variable refresh rate displays may prefer Medium settings to ensure framerates never dip near the minimum thresholds.

CPU Role

The Intel Core Ultra 5 235HX provides the computational foundation for this gaming combination, and its specifications suggest it's more than adequate for Downfall's demands. The 14-core, 14-thread configuration with a 2.90 GHz base clock and 5.10 GHz boost clock delivers strong single-threaded performance, as evidenced by the 4903 Cinebench R23 single-core score and 4683 PassMark single-thread score. The 24 MB shared L3 cache and 102.4 GB/s memory bandwidth provide the data throughput necessary for feeding the GPU at high framerates.

The CPU's 91st percentile ranking among all CPUs, with an average benchmark score of 52073, places it in elite company. Its nearest rivals include the AMD EPYC 8124P (deltaPct -0.1), AMD Ryzen 9 5950X (deltaPct 0.2), Intel Core i7-14700 (deltaPct -0.4), and Intel Core i9-13900F (deltaPct 0.7). These sub-1% deltas indicate the 235HX performs within a hair of desktop-class processors from previous generations, despite being a mobile chip with a 55 W TDP.

The 1080p Low result of 287 FPS serves as the clearest indicator of CPU capability. This framerate represents a scenario where the GPU is lightly loaded, meaning the CPU must generate and submit draw calls faster than 287 times per second. The fact that the 235HX sustains this rate without bottlenecking suggests its 5.10 GHz boost clock and Arrow Lake architecture provide ample single-thread throughput for even the most demanding esports-style scenarios.

The Cinebench R23 multicore score of 34731 and PassMark multithread score of 40849 demonstrate that the CPU scales well across its 14 cores, though Downfall's 2016 release likely doesn't utilize more than a few threads. The PassMark physics score of 2550 and find prime numbers score of 361 indicate strong integer and floating-point performance, which translates to consistent frame delivery in physics-heavy game scenes. The CPU's 3 nm process node and 17,800 million transistors on a 243 mm² die contribute to its efficiency, though the TDP of 55 W is modest compared to desktop counterparts.

How This Combo Ranks

The combination of Intel Core Ultra 5 235HX and NVIDIA GeForce RTX 4080 Mobile achieves a rank of 1219 out of 3716 tested combinations in Downfall, placing it in the 67.2nd percentile of all system pairings. This ranking reflects the hardware's strong but not elite performance tier, consistent with the individual component percentiles (CPU at 91st, GPU at 81st percentile).

The rank suggests that while both components are individually capable, the pairing doesn't reach the top tiers of performance. This could be attributed to the GPU's mobile power envelope limiting its sustained performance compared to desktop variants, or the CPU's 14-thread configuration providing more compute than Downfall can utilize. The 3716 total combinations indicate a diverse testing pool, and the 1219 rank places this combo in the upper third of all systems tested.

The deltaPct values from the nearest rival benchmarks provide context for where this hardware sits. The CPU's closest rival, the Intel Core i9-13900F, scores 0.7% higher in average benchmarks, while the GPU's closest rival, the RTX 4070, scores 1.3% lower. These small differences suggest that component selection within this performance tier yields minimal impact on overall system capability. The combo rank of 1219, combined with the strong measured FPS data, indicates that this pairing delivers excellent real-world gaming performance even if it doesn't crack the top 1000 combinations.

The measured FPS results across all twelve configurations consistently exceed 53 FPS, with most results well above 85 FPS. This real-world performance validates the hardware combination as a capable gaming system for Downfall, particularly at 1440p where it excels across all settings. The 4K Ultra result of 53 FPS represents the only configuration that approaches the lower bounds of playability, and even this result is usable with adaptive sync technology. The rank of 1219, while not top-tier, reflects a system that handles this horror title with aplomb across the vast majority of tested scenarios.
