Downfall

The data for Downfall with the Intel Core Ultra 7 155H and NVIDIA GeForce RTX 5080 shows a system that is heavily skewed toward GPU performance, with the CPU providing ample headroom even at lower resolutions. The measured FPS figures reveal a clear pattern of scaling that shifts from a CPU-bound scenario at 1080p to a GPU-bound scenario at 4K, though the RTX 5080 remains the dominant force throughout.

Resolution Scaling

The transition from 1080p to 4K produces a substantial performance drop that is consistent with a high-end GPU being pushed progressively harder. At High settings, the average frame rate falls from 206 FPS at 1920x1080 to 147 FPS at 2560x1440, a reduction of 59 FPS. Moving to 3840x2160, the average drops further to 92 FPS, which represents a 55 FPS decline from the 1440p result. This linear degradation pattern indicates that the RTX 5080 is the primary limiting component at all three resolutions, but the pace of the drop suggests the CPU begins to matter less as the resolution increases.

The Low settings data tells a more revealing story about the system's balance. At 1920x1080 Low, the system produces 308 FPS average, which is an extraordinarily high figure that likely approaches the engine's frame rate cap or the CPU's practical limit. When resolution increases to 2560x1440 Low, the average drops to 220 FPS, and at 3840x2160 Low it reaches 137 FPS. The percentage drop from 1080p to 1440p is approximately 28.6%, while the drop from 1440p to 4K is approximately 37.7%. This widening gap at lower settings is the classic signature of a GPU that is becoming the bottleneck, as the CPU has more than enough headroom to feed frames at 1080p but the GPU's workload grows exponentially with pixel count.

Medium settings provide the most complete data set, including minimum and maximum frame rates. At 1920x1080 Medium, the average is 252 FPS with a minimum of 214 FPS and a maximum of 289 FPS. At 2560x1440 Medium, those numbers shift to 180 FPS average, 153 FPS minimum, and 207 FPS maximum. The 4K Medium result shows 112 FPS average, 95 FPS minimum, and 129 FPS maximum. The minimum frame rates scale almost perfectly with the averages, suggesting the game maintains consistent frame pacing without sudden stutters or drops. The spread between minimum and maximum remains relatively tight at each resolution, which is a positive sign for gameplay smoothness.

The Ultra settings data reveals the most dramatic resolution scaling. At 1080p Ultra, the system achieves 129 FPS average. At 1440p Ultra, this falls to 92 FPS, and at 4K Ultra, it plummets to 57 FPS. The 4K Ultra result is notably below the 60 FPS threshold that many players consider the minimum for smooth gameplay, and it represents a 55.8% reduction from the 1080p Ultra score. This steep decline at the highest settings and resolution combination demonstrates that the RTX 5080, despite its considerable power, faces a significant challenge with Downfall's Ultra preset at 4K.

The overall pattern across all settings indicates that the system is well-balanced for 1440p gaming, with all settings producing playable frame rates. At 4K, however, only Low and Medium settings maintain averages above 100 FPS, while High dips to 92 FPS and Ultra falls to 57 FPS. The data suggests that players targeting 4K Ultra will need to accept a sub-60 FPS experience or reduce settings, while 1440p Ultra at 92 FPS offers a much more comfortable margin.

GPU Role

The NVIDIA GeForce RTX 5080 is the clear performance driver in this configuration. Its 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, which is a substantial resource for a horror title like Downfall that likely features dark, detailed environments with heavy texture usage. The GPU's 10752 shading units, 336 texture mapping units, and 112 render output units provide the raw compute horsepower needed to maintain high frame rates across all tested resolutions.

The clock speeds of the RTX 5080 are notable, with a base clock of 2295 MHz and a boost clock of 2617 MHz. These figures are high for a modern GPU and contribute directly to the strong performance observed in the benchmark data. The 56.28 TFLOPS of FP32 compute is a massive amount of processing power, and the GPU's 84 ray tracing cores and 336 tensor cores suggest it is well-equipped for any modern rendering techniques Downfall might employ.

The GPU's benchmark scores corroborate its in-game performance. The 3DMark Steel Nomad DX12 score of 8637 and the Passmark G3D score of 36565 place it in the 87th percentile of all GPUs. The Geekbench OpenCL score of 235901 and Vulkan score of 255450 further confirm its compute capabilities. The RTX 5080's average benchmark score of 56083 is competitive, with its nearest rivals being the AMD Radeon 8060S at 55757 (0.6% slower) and the AMD Radeon RX 6750 GRE 12 GB at 55698 (0.7% slower). The AMD Radeon RX 9070 GRE is 2.2% faster with a score of 57367, but the margin is relatively small in the context of overall GPU performance.

The VRAM capacity of 16 GB is a significant advantage for Downfall, as horror games often use high-resolution textures to create detailed, immersive environments. The 960.0 GB/s memory bandwidth ensures that the GPU can feed its 10752 shading units without starving them of data. This is particularly important at 4K resolution, where the pixel workload increases dramatically. The data shows that the GPU remains the bottleneck even at 4K Low settings with 137 FPS average, which indicates that the RTX 5080 is being fully utilized in this configuration.

How This Combo Ranks

The combination of the Intel Core Ultra 7 155H and NVIDIA GeForce RTX 5080 ranks 1016 out of 3716 tested combos in Downfall, placing it in the top 27.3% of all configurations. This is a respectable position, though not a top-tier ranking, which suggests that the CPU component is holding the system back from achieving a higher placement. The combo's rank is likely influenced by the fact that the Core Ultra 7 155H is a mobile processor, and its performance characteristics differ from desktop CPUs that might pair more naturally with a flagship GPU like the RTX 5080.

The CPU's average benchmark score of 32697 places it in the 83rd percentile of all CPUs, which is solid but not exceptional. Its nearest rivals in the CPU benchmark database include the Intel Core i5-14600T at 32707 (0% difference), the AMD Ryzen AI 7 PRO 360 at 32662 (0.1% faster), the AMD Ryzen 5 7400F at 32750 (0.2% slower), and the AMD Ryzen 7 PRO 6850H at 32812 (0.4% slower). These are all closely matched scores, indicating that the Core Ultra 7 155H is a mid-pack performer in synthetic benchmarks, which aligns with its 1016 rank in the game-specific combo list.

The gap between the CPU's 83rd percentile ranking and the combo's 27.3rd percentile ranking in Downfall suggests that the game is more dependent on GPU performance than CPU performance. However, the combo rank still indicates that there are many faster configurations, likely featuring desktop-class CPUs that can better keep pace with the RTX 5080's frame output at lower resolutions. The data shows that at 1080p Low, the system achieves 308 FPS, which is a very high number, but it is possible that a stronger CPU could push this figure even higher if the game's engine allows it.

Measured FPS Breakdown

The complete measured FPS data for this configuration covers three resolutions and four settings levels, providing a thorough picture of performance.

At 1920x1080, the system delivers its highest frame rates. Low settings produce an average of 308 FPS. Medium settings yield 252 FPS average, with a minimum of 214 FPS and a maximum of 289 FPS. High settings achieve 206 FPS average. Ultra settings drop to 129 FPS average. The progression from Low to Ultra shows a consistent decline of roughly 50-60 FPS between each settings tier, with Ultra representing a 58.1% reduction from Low.

At 2560x1440, performance remains strong but noticeably lower. Low settings produce 220 FPS average. Medium settings achieve 180 FPS average, with a minimum of 153 FPS and a maximum of 207 FPS. High settings reach 147 FPS average. Ultra settings fall to 92 FPS average. The step from High to Ultra at 1440p is a 55 FPS drop, which is the largest single-tier decline at this resolution, highlighting the demanding nature of the Ultra preset.

At 3840x2160, the system's performance becomes more constrained. Low settings produce 137 FPS average. Medium settings achieve 112 FPS average, with a minimum of 95 FPS and a maximum of 129 FPS. High settings reach 92 FPS average. Ultra settings fall to 57 FPS average. The 4K Ultra result is the only data point below 60 FPS, and the 35 FPS drop from High to Ultra at this resolution is the most severe single-tier penalty observed in the entire dataset.

The Medium settings data is the only tier with complete minimum and maximum values at all three resolutions, and it shows a consistent pattern. The minimum frame rates are always above 90% of the average, and the maximums are always within 15-20% above the average. This tight clustering indicates stable performance without significant frame time spikes, which is important for a horror game where smooth motion is essential for maintaining atmosphere and immersion.

CPU Role

The Intel Core Ultra 7 155H is a 16-core, 22-thread mobile processor based on the Meteor Lake architecture. It has a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with a 28 W TDP. The CPU's cache configuration includes 112 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. This is a capable processor for gaming, though its mobile design and relatively modest TDP limit its sustained performance compared to desktop alternatives.

The CPU's benchmark results show a strong multi-core showing with a Cinebench R23 multi-core score of 15028, but a more modest single-core score of 1743. The Passmark multi-thread score of 24873 and single-thread score of 3468 reflect this pattern. The data compression score of 277353 and integer math score of 86870 indicate solid general-purpose performance, while the floating point math score of 63703 and extended instructions score of 16456 show competent compute capabilities.

In the context of Downfall, the CPU's role appears to be secondary to the GPU. The fact that the system achieves 308 FPS at 1080p Low suggests that the CPU is capable of feeding frames at a very high rate, but the 28.6% drop from 1080p Low to 1440p Low indicates that the GPU becomes the limiting factor as resolution increases. The CPU's 22 threads and 16 cores are more than sufficient for a horror game, which typically does not heavily utilize multi-threading beyond a few cores.

The CPU's memory bandwidth of 89.6 GB/s on a dual-channel DDR5 bus could potentially be a bottleneck in some scenarios, but the data does not suggest this is a significant issue in Downfall. The system maintains high frame rates even at 1080p, where CPU-bound scenarios would typically manifest. The boost clock of 4.80 GHz is respectable for a mobile chip, and the single-core performance, as measured by the Cinebench R23 score of 1743, is adequate for gaming workloads that rely on a few fast cores.

The CPU's 83rd percentile ranking among all CPUs, combined with the combo's 1016th rank out of 3716 in Downfall, reinforces the idea that the processor is not the primary performance limiter in this configuration. The data indicates that the CPU provides sufficient headroom for the RTX 5080 to operate near its full potential at most settings, with the exception being the extremely high frame rates at 1080p Low where a faster desktop CPU might yield marginal improvements.
