Downfall

The AMD Ryzen AI Max+ 395 paired with the AMD Radeon RX 7800M presents a compelling mobile platform for playing Downfall, a 2016 horror title. The measured data shows a combination capable of delivering very high frame rates at mainstream resolutions, but with a clear performance ceiling at 4K that demands settings adjustments. This analysis breaks down the measured FPS across resolutions and settings, contextualizes the CPU and GPU roles, and provides practical advice based solely on the provided benchmark data.

Resolution Scaling

The FPS data reveals a classic pattern of GPU-bound scaling as resolution increases. At 1080p with High settings, the combo produces 130 FPS. Moving to 1440p drops that to 93 FPS, a 28% reduction. The jump to 4K is even more severe, with the average falling to 58 FPS, a 55% drop from the 1080p result. This steep decline indicates that the Radeon RX 7800M is the primary limiting factor at higher resolutions, while the CPU has ample headroom to feed it at 1080p.

The scaling pattern is consistent across all settings. At Low settings, the frame rate goes from 194 FPS at 1080p, to 139 FPS at 1440p, and finally to 86 FPS at 4K. The percentage drops are 28% and 56% respectively, mirroring the High preset’s behavior almost exactly. This uniformity suggests that the performance scaling is governed by the GPU’s raw fill rate and memory bandwidth, which are being saturated as pixel count increases, rather than by any CPU bottleneck.

At Ultra settings, the pattern holds but the absolute numbers are much lower. The combo manages 81 FPS at 1080p, 58 FPS at 1440p, and 36 FPS at 4K. The drop from 1080p to 1440p is 28%, and from 1440p to 4K it is 38%. The 4K Ultra result of 36 FPS is the only measured point below the 60 FPS threshold, confirming that this resolution and preset combo is too demanding for the GPU. The data shows that for consistent high-refresh gameplay, sticking to 1080p or 1440p is necessary, while 4K is only viable with lower settings.

CPU Role

The AMD Ryzen AI Max+ 395 is a 16-core, 32-thread processor based on the Zen 5 architecture, with a base clock of 3.00 GHz and a boost clock of 5.10 GHz. Its benchmark scores are strong, with a Cinebench R23 multi-core score of 35,314 and a single-core score of 2,044. This places it in the 95th percentile of all CPUs tested, indicating it is a high-end mobile part.

In Downfall, the CPU’s role appears to be secondary to the GPU. At 1080p, where the GPU is less stressed, the CPU’s performance is sufficient to drive frame rates well above 130 FPS on High settings. The data shows no indication of a CPU bottleneck, as the frame rate drops consistently with increasing resolution, which is the signature of a GPU limit. The CPU’s high single-core performance, evidenced by its Geekbench single-core score of 2,464, is likely more than adequate for the game’s logic and physics.

Compared to its nearest rivals, the CPU performs as expected. Its average benchmark score of 77,740 is 1.6% higher than the AMD Ryzen Threadripper PRO 9945WX and the AMD EPYC Embedded 8224P, and 2% higher than the AMD Ryzen 9 8945HX. It is 1.7% lower than the Intel Core i9-14900K. These tiny deltas mean that in a game like Downfall, which is not heavily multithreaded, the choice between these CPUs would have a negligible impact on the final FPS. The CPU’s 64 MB of shared L3 cache and 256.0 GB/s of memory bandwidth provide a solid foundation for feeding the GPU, but they are not the deciding factor in the measured results.

Settings Recommendations

The measured FPS data offers a clear hierarchy of settings for different priorities. For players targeting 60 FPS as a baseline, the High preset is the sweet spot at 1440p, delivering 93 FPS. At 4K, the High preset’s 58 FPS is just shy of the 60 FPS mark, making Medium the better choice for a locked experience. At 1080p, the High preset’s 130 FPS is excellent, and even Ultra’s 81 FPS is playable, but the jump to Medium at 159 FPS or Low at 194 FPS is substantial for competitive or high-refresh-rate displays.

For the best balance of visual quality and performance, the Medium preset stands out. At 1440p, it delivers 114 FPS with a minimum of 97 FPS, providing a smooth experience with only a modest visual downgrade from High. At 4K, Medium’s 71 FPS is the only preset that comfortably exceeds the 60 FPS target, making it the recommended choice for 4K displays. The data shows a consistent pattern: High is for 1080p and 1440p, Medium is for 4K, and Ultra is only viable at 1080p for those who prioritize image quality over frame rate.

The Low preset’s performance gains are significant—194 FPS at 1080p and 86 FPS at 4K—but the visual sacrifice is likely too steep for a horror game where atmosphere matters. The Ultra preset’s 36 FPS at 4K is not recommended, as it falls below playable thresholds. Based on the measured rows, the practical recommendation is to use High at 1080p or 1440p for a great experience, and to switch to Medium for 4K. This approach ensures a stable frame rate without unnecessarily compromising visual fidelity.

How This Combo Ranks

In the database of tested combinations for Downfall, this specific pairing of the AMD Ryzen AI Max+ 395 and AMD Radeon RX 7800M ranks 1,931 out of 2,928 total combos. This places it in the lower half of all tested systems, which is surprising given the individual components’ strong benchmark scores. The CPU’s 95th percentile ranking and the GPU’s 73rd percentile ranking suggest a capable pair, but the game’s overall performance ranking indicates that many other combos achieve higher frame rates in this specific title.

The rank of 1,931 suggests that while the combo is competent, it is not optimized for Downfall’s specific workload. This is likely due to the GPU’s mid-range positioning. The Radeon RX 7800M’s average benchmark score of 27,883 is nearly identical to its nearest rivals—the AMD Radeon Pro Vega 20 (27,839, +0.2%), the AMD Radeon Pro W5500X (27,973, -0.3%), and the NVIDIA GeForce GTX 980 Ti (28,020, -0.5%). These sub-1% differences mean that in terms of raw GPU compute, this card is on par with those older models, which likely explains the mid-pack ranking in a game that is sensitive to GPU throughput.

The combo’s rank is not a reflection of the CPU’s capability, but rather a consequence of the GPU’s performance ceiling. The data shows that the CPU is far more powerful than the GPU, as evidenced by the significant FPS drops when moving to higher resolutions. If the GPU were stronger, this combo would likely rank much higher. As it stands, the rank of 1,931 out of 2,928 indicates that users should temper their expectations for maximum settings at high resolutions, but the measured FPS shows it is still a very playable combo at 1080p and 1440p.

GPU Role

The AMD Radeon RX 7800M is the defining component in this combo’s gaming performance. It features 12 GB of GDDR6 memory on a 192-bit bus, providing 432.0 GB/s of bandwidth. Its boost clock of 2335 MHz and 3840 shading units give it a theoretical FP32 performance of 35.87 TFLOPS. The GPU’s benchmark scores, such as a 3DMark Steel Nomad DX12 score of 2,994 and a Geekbench Vulkan score of 126,668, place it in the 73rd percentile of all GPUs.

In Downfall, the GPU’s role is clearly the bottleneck at higher resolutions. The 12 GB VRAM is sufficient for the game’s demands, as the frame rates are more limited by compute throughput than memory capacity. The 432.0 GB/s bandwidth is adequate for 1080p and 1440p, but the 4K results show a sharp decline, indicating that the memory interface and raw pixel throughput are being stressed. The 96 ROPs and 240 TMUs provide solid fill rates, but they are not enough to maintain high FPS at 4K Ultra.

The GPU’s performance is consistent with its benchmark positioning. Its nearest rival, the NVIDIA GeForce GTX 980 Ti, has a nearly identical average score (28,020 vs 27,883), and the measured FPS in Downfall reflects this parity. The GPU’s 35.87 TFLOPS of FP32 compute is its main strength, but in a DirectX 12 title, the architecture’s efficiency matters more than raw TFLOPS. The data shows that the RX 7800M is a capable 1080p and 1440p card, but it struggles to maintain high frame rates at 4K, especially on the Ultra preset where the 36 FPS average is the weakest result in the entire dataset.

| 1920x1080 | Ultra | 81 | - | - |

At 1080p, the combo delivers excellent performance across all settings. Low hits 194 FPS, Medium 159 FPS, and High 130 FPS, all well above the 60 FPS threshold. Ultra is the only setting that drops below 100 FPS, but 81 FPS is still smooth. The minimum FPS data for Medium shows 135 FPS, indicating stable frame pacing.

At 1440p, the performance remains strong. Low reaches 139 FPS, Medium 114 FPS, and High 93 FPS. Ultra again is the outlier at 58 FPS, which is just below the 60 FPS mark. The Medium preset’s minimum of 97 FPS shows good consistency. For 4K, the results are more varied. Low achieves 86 FPS, Medium 71 FPS, and High 58 FPS. Ultra is the only unplayable option at 36 FPS. The Medium preset’s minimum of 60 FPS means it is the only 4K setting that guarantees a smooth experience.

These numbers paint a clear picture: the combo is ideal for 1080p and 1440p gaming, with headroom for high refresh rates. At 4K, it requires a compromise on settings, with Medium being the recommended preset for a playable experience. The lack of min/max data for most settings means we cannot assess frame time spikes, but the available data for Medium presets shows acceptable consistency.
