Downfall

# Downfall — Intel Core Ultra 7 155H + AMD Radeon RX 7900M

The combination of the Intel Core Ultra 7 155H and AMD Radeon RX 7900M delivers a compelling mobile gaming experience in Downfall, a horror title from 2016 that remains demanding at higher presets. This pairing ranks in the 58th percentile of tested configurations, with the GPU clearly dominating the performance profile across most settings and resolutions. The data reveals a system that can handle 1440p High with ease but struggles to maintain playable frame rates at 4K Ultra, offering a clear picture of where the hardware's limits lie.

Resolution Scaling

Downfall's performance scales predictably as resolution increases, but the pattern reveals important characteristics about this specific hardware pairing. At 1080p Low, the system achieves 257 FPS average, which drops to 183 FPS at 1440p Low and further to 114 FPS at 4K Low. This represents a 29% reduction from 1080p to 1440p and a 38% reduction from 1440p to 4K. The scaling is consistent with GPU-bound behavior, where each pixel count increase directly impacts the rendering load.

Looking at High settings, the scaling pattern shifts slightly. The system delivers 172 FPS at 1080p, 123 FPS at 1440p, and 76 FPS at 4K. The percentage drops are 28% from 1080p to 1440p and 38% from 1440p to 4K, nearly identical to the Low preset percentages. This consistency suggests the GPU is the primary limiting factor across all settings, with the CPU providing sufficient headroom to avoid bottlenecking even at lower resolutions where frame rates exceed 250 FPS.

Medium settings show a similar trajectory: 210 FPS at 1080p, 150 FPS at 1440p, and 93 FPS at 4K. The min-to-max FPS spread at Medium settings is remarkably tight, with 178-241 FPS at 1080p (a 63 FPS range), 127-172 FPS at 1440p (45 FPS range), and 79-107 FPS at 4K (28 FPS range). This narrowing range at higher resolutions indicates that frame time consistency improves as the GPU becomes more saturated, reducing the variance caused by CPU-side frame pacing.

Ultra settings present the most dramatic scaling. The system produces 108 FPS at 1080p, 77 FPS at 1440p, and only 48 FPS at 4K. The 4K Ultra result falls below the 60 FPS threshold commonly considered minimum for smooth gameplay, suggesting that this configuration is not suitable for maximum settings at native 4K. The scaling from 1440p to 4K at Ultra represents a 38% drop, consistent with other presets, but the absolute values are low enough that the experience degrades noticeably.

The overall pattern strongly indicates GPU-bound performance. If the CPU were the limiting factor, we would expect to see frame rates plateau at lower resolutions, particularly at Low settings where the GPU workload is lightest. Instead, the system scales almost linearly with pixel count, a hallmark of a configuration where the Radeon RX 7900M is doing the heavy lifting and the Core Ultra 7 155H is keeping pace without becoming a constraint.

How This Combo Ranks

Among 2,928 tested combinations in Downfall, this pairing achieves rank 1,219, placing it in the 58th percentile of all configurations. This mid-pack positioning reflects a balanced but not exceptional performance profile; the system outperforms a majority of tested combos but is clearly not at the top tier for this title.

The GPU's individual ranking is notably stronger than the combo ranking. The Radeon RX 7900M sits in the 94th percentile among all GPUs, indicating that the graphics card itself is a high-performing component. This discrepancy between GPU percentile and combo rank suggests that the overall system performance is being held back by factors other than pure GPU capability, likely the CPU or memory subsystem in certain scenarios.

The CPU's percentile ranking is 83rd among all processors, which is respectable but below the GPU's standing. The Core Ultra 7 155H's average benchmark score of 32,697 places it very close to several competitors: the Intel Core i5-14600T scores 32,707 (a 0% delta), the AMD Ryzen AI 7 PRO 360 scores 32,662 (0.1% faster), the AMD Ryzen 5 7400F scores 32,750 (0.2% slower), and the AMD Ryzen 7 PRO 6850H scores 32,812 (0.4% slower). These near-identical scores indicate that the 155H is competitively positioned within its performance class, but it does not stand out from its immediate rivals.

The combo rank of 1,219 out of 2,928 suggests that in Downfall specifically, this hardware pairing performs adequately but not spectacularly. The game's horror genre often involves complex lighting and shadow effects, which can be demanding on both CPU and GPU. The mid-pack ranking indicates that while the system is capable, it does not achieve the top-tier results that the GPU's 94th percentile might suggest, implying some degree of CPU limitation in certain scenarios or that the specific combination does not synergize optimally for this title.

CPU Role

The Intel Core Ultra 7 155H features 16 cores and 22 threads based on the Meteor Lake architecture, manufactured on Intel's 7 nm process. Its base clock of 3.80 GHz and boost clock of 4.80 GHz provide substantial single-threaded performance headroom, which is relevant for Downfall's game logic and physics calculations. The processor's 24 MB of shared L3 cache helps maintain data locality for frequently accessed game assets.

In synthetic benchmarks, the 155H demonstrates strong multi-threaded capability with a Cinebench R23 multi-core score of 15,028 and a single-core score of 1,743. The PassMark single-thread score of 3,468 indicates solid per-core performance, while the multi-thread score of 24,873 shows good scaling across cores. These numbers suggest the CPU can handle the demands of a modern game like Downfall without becoming a bottleneck in most scenarios.

The nearest CPU rivals all score within 0.4% of the 155H's average benchmark score, which means the processor is essentially performance-equivalent to several other mid-range options. This parity is important because it means the combo's ranking in Downfall is primarily determined by the GPU and how well the two components interact, rather than by the CPU being either exceptionally strong or weak relative to its peers.

For Downfall, the CPU's role appears to be supportive rather than dominant. At 1080p Low, where the GPU workload is lightest and frame rates reach 257 FPS, the CPU must deliver frames quickly enough to keep the GPU fed. The fact that the system achieves such high frame rates at this setting indicates the 155H has sufficient single-threaded performance to avoid becoming a limiting factor, even at high frame rates where CPU overhead becomes more significant.

However, the 83rd percentile CPU ranking versus the 94th percentile GPU ranking suggests that in compute-heavy scenes, the processor may not fully complement the graphics card's capabilities. This could manifest as occasional frame hitches or reduced performance in CPU-intensive sequences, though the measured data shows generally smooth performance across most settings and resolutions.

Measured FPS Breakdown

At 1080p, the system delivers excellent performance across all presets. Low settings produce 257 FPS average, which is exceptionally high and indicates the game is well-optimized for lower-end workloads at this resolution. Medium settings yield 210 FPS with a min of 178 FPS and max of 241 FPS, providing a smooth experience with minimal frame time variance. High settings achieve 172 FPS, still well above the threshold for high-refresh-rate displays. Ultra settings drop to 108 FPS, which remains playable but represents a significant step down from the other presets, reflecting the increased rendering complexity at maximum quality.

At 1440p, the performance remains strong but shows the expected reduction. Low settings deliver 183 FPS, Medium produces 150 FPS with a min of 127 FPS and max of 172 FPS, and High achieves 123 FPS. Ultra settings drop to 77 FPS, which is still above 60 FPS and provides a playable experience, though the gap between Ultra and High (46 FPS difference) is substantial. The min-max range at Medium settings (127-172 FPS) indicates good consistency, with only a 45 FPS spread.

At 4K, the system's limits become apparent. Low settings achieve 114 FPS, which is respectable for 4K gaming. Medium settings produce 93 FPS with a min of 79 FPS and max of 107 FPS, maintaining playability. High settings drop to 76 FPS, which is still above 60 FPS and provides a smooth experience. Ultra settings, however, fall to 48 FPS, which is below the 60 FPS threshold and may result in noticeable stuttering during fast-paced scenes. This 4K Ultra result represents the only measured configuration that fails to maintain acceptable frame rates.

The data shows that the system's sweet spot is 1440p, where it can deliver high frame rates at High settings while maintaining good visual quality. At 1080p, the system is capable of extremely high frame rates, making it suitable for competitive play or high-refresh-rate displays. At 4K, users will need to compromise on settings to achieve smooth performance, with Medium or Low being the recommended presets.

Settings Recommendations

For users prioritizing smooth gameplay, the data clearly indicates that Medium settings offer the best balance of performance and visual quality across all resolutions. At 1080p Medium, the system delivers 210 FPS with a minimum of 178 FPS, ensuring consistent frame delivery. At 1440p Medium, 150 FPS average with a 127 FPS minimum provides an excellent experience on high-refresh-rate monitors. At 4K Medium, 93 FPS average with a 79 FPS minimum remains comfortably above 60 FPS.

High settings are also viable for users who prioritize visual fidelity over maximum frame rates. At 1440p High, 123 FPS is sufficient for smooth gameplay, and at 4K High, 76 FPS provides a playable experience. The 4K High setting represents the highest visual quality that maintains acceptable performance at that resolution.

Ultra settings should be avoided at 4K, where the 48 FPS average falls below playable thresholds. At 1440p Ultra, 77 FPS is playable but represents a significant performance cost over High settings (46 FPS difference) for what may be marginal visual improvements. At 1080p Ultra, 108 FPS is acceptable but again comes at a substantial cost versus High settings (64 FPS difference).

The optimal recommendation is 1440p High for the best combination of visual quality and performance. This setting delivers 123 FPS, which is high enough for smooth gameplay on most displays while providing enhanced visual detail over Medium. For users with 4K displays, 4K Medium at 93 FPS offers the best balance, while those with 1080p displays can comfortably use High settings at 172 FPS or even Ultra at 108 FPS if visual quality is paramount.

GPU Role

The AMD Radeon RX 7900M is the dominant component in this configuration, ranking in the 94th percentile among all GPUs. Its performance class is demonstrated by an average benchmark score of 97,487, placing it slightly above the AMD Radeon Pro VII (97,131, 0.4% faster) and significantly ahead of the AMD Radeon Instinct MI60 (92,466, 5.4% faster) and NVIDIA RTX A4500 (91,671, 6.3% faster). The NVIDIA Quadro RTX 6000 scores higher at 101,872 (4.3% faster), but the 7900M remains competitive in its class.

The GPU's specifications support its strong performance. With 16 GB of GDDR6 memory on a 256-bit bus, the card provides 576.0 GB/s of memory bandwidth, which is ample for 4K textures and high-resolution rendering. The 4,608 shading units and 192 ROPs enable high pixel throughput, while the 72 ray-tracing cores provide hardware acceleration for advanced lighting effects common in horror games. The boost clock of 2090 MHz and base clock of 1825 MHz, combined with the RDNA 3.0 architecture on a 5 nm process, deliver substantial compute capability.

In benchmark tests, the 7900M achieves a 3DMark Steel Nomad DX12 score of 4,201, a Geekbench OpenCL score of 129,499, and a Geekbench Vulkan score of 158,760. These results indicate strong DirectX 12 and Vulkan performance, which is relevant for Downfall's rendering pipeline.

The GPU's 94th percentile ranking versus the combo's 58th percentile ranking highlights that the graphics card is significantly more capable than the overall system performance suggests. This disparity is likely due to the CPU not fully enabling the GPU's potential in all scenarios, though the measured frame rates show that the GPU is clearly the primary driver of performance. The consistent resolution scaling and the fact that frame rates drop proportionally with pixel count confirm that the RX 7900M is the limiting component at higher resolutions, while at lower resolutions the CPU may occasionally constrain performance.

The 180 W TDP indicates a high-power mobile GPU, and the "IGP" slot width suggests this is a laptop-integrated solution rather than a discrete card. The PCIe 4.0 x16 interface provides sufficient bandwidth for the GPU's data requirements, and the 57,700 million transistors on a 529 mm² die demonstrate the complexity of this chip. For Downfall specifically, the GPU's strong performance at Medium and High settings across all resolutions confirms that it is well-suited for this title, with the main limitation being the 4K Ultra preset where even this powerful GPU cannot maintain 60 FPS.
