Downfall

The AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 4080 delivers strong frame rates in Downfall, a 2016 horror title. Measured data shows the combo averaging 192 FPS at 1080p High, 137 FPS at 1440p High, and 85 FPS at 4K High. This configuration ranks 1219th out of 3716 tested combos, placing it above the median for the game. The following sections break down how the system scales across resolutions, the GPU and CPU contributions, and how this specific pairing compares to other tested configurations.

Resolution Scaling

Resolution scaling reveals how the workload shifts between the CPU and GPU. In Downfall, the average frame rate drops consistently when moving from 1080p to 4K across all four settings presets. At High settings, the average goes from 192 FPS at 1080p to 137 FPS at 1440p, then to 85 FPS at 4K — a reduction of roughly 56% from 1080p to 4K. The Low preset follows the same pattern: 287 FPS at 1080p, 205 FPS at 1440p, and 127 FPS at 4K, a 55.7% drop. Medium settings show 235 FPS at 1080p, 168 FPS at 1440p, and 104 FPS at 4K, again a 55.7% decrease. Ultra settings are the most demanding: 120 FPS at 1080p, 86 FPS at 1440p, and 53 FPS at 4K, a 55.8% reduction.

The uniformity of this scaling — all four presets lose roughly the same fraction of performance when moving from 1080p to 4K — points directly at the GPU as the limiting component at higher resolutions. The CPU’s workload does not change much with resolution, so if the CPU were the bottleneck, the FPS drop would be less severe as the resolution rises. Instead, the consistent 56% decline indicates that the rendering load at 1440p and 4K is taxing the GPU far more than the CPU. At 1080p, the CPU can push high frame rates, but the GPU becomes the primary constraint as pixel count grows. Notably, the 4K Ultra average of 53 FPS is below the 60 FPS threshold commonly used for smooth play, making 4K Ultra a borderline setting for this combo.

The pattern also shows that the CPU is not holding the system back at any resolution. At 1080p Low, the average reaches 287 FPS, which is far beyond the refresh rate of most monitors, indicating the CPU can feed the GPU with very high frame counts. The GPU’s performance at 1080p is also strong — 192 FPS at High and 120 FPS at Ultra — but the consistent drop at 4K confirms that the GPU is the primary limiting factor for the highest resolution.

FAQ

GPU Role

The NVIDIA GeForce RTX 4080 is the primary graphics processor in this combo. Its 16 GB of GDDR6X memory on a 256-bit bus delivers 716.8 GB/s of bandwidth, which is ample for the textures and effects in Downfall. The GPU’s clocks are listed as a base of 2205 MHz and a boost of 2505 MHz, with memory running at 1400 MHz (22.4 Gbps effective). These clock speeds contribute to the GPU’s raw throughput: it reaches 48.74 TFLOPS of FP32 performance, a figure that places it among the higher end of the GeForce 40-series.

The GPU’s benchmark results further clarify its standing. In Passmark, it scores 34,457 in the G3D test, which puts it in the 86th percentile of all GPUs. Its average benchmark score is 54,247, and it sits very close to its nearest rivals: the RTX 4080 SUPER is only 0.1% higher (54,209), while the AMD Radeon Pro W5700X is 1.1% lower (54,828), and the Radeon RX 6750 GRE 12 GB is 2.6% lower (55,698). This means the RTX 4080 is essentially on par with the 4080 SUPER in synthetic tests, and it is significantly ahead of the other GPUs in the comparison set.

In Downfall, the GPU’s role is clearly visible in the resolution scaling. At 4K Ultra, the average FPS falls to 53, which is the lowest measured value in the dataset. The GPU’s compute and memory bandwidth are stretched at 4K Ultra, leading to the sub-60 result. However, at 1080p, the GPU delivers 120 FPS at Ultra and 192 FPS at High, showing that it is not a bottleneck at lower resolutions. The 16 GB of VRAM is more than adequate for the game’s demands, as the measured frame rates remain high at 4K High (85 FPS) and Medium (104 FPS). The GPU’s 320 W TDP and triple-slot design are physical characteristics, but the benchmark data does not indicate any thermal throttling or power-related issues affecting frame rates.

At 1080p, the system is clearly capable of high refresh-rate gaming. The Low preset averages 287 FPS, and even the Ultra preset stays at 120 FPS. The Medium preset shows a narrow range between 199 and 270 FPS, indicating stable frame pacing. Moving to 1440p, the averages are still high: 205 FPS on Low, 168 FPS on Medium, 137 FPS on High, and 86 FPS on Ultra. The 1440p Medium range of 142–193 FPS shows a wider variance than at 1080p, but still remains smooth. At 4K, the GPU becomes the clear limiting factor. The Low preset averages 127 FPS, which is playable, but the Ultra preset drops to 53 FPS, which is below the 60 FPS comfort threshold. The 4K Medium range of 89–120 FPS is usable, but the High preset at 85 FPS is close to the edge.

How This Combo Ranks

The combination of the Ryzen 9 8945HX and RTX 4080 ranks 1219th out of 3716 tested configurations in Downfall. This means 1218 other combos score higher, while 2497 combos are slower — the setup is better than about 67.2% of all tested pairings. The ranking is based on measured FPS data, which puts this combo in the upper half of the distribution, but not at the very top.

The CPU alone sits in the 95th percentile of all CPUs, with an average benchmark score of 76,212. The GPU is in the 86th percentile of all GPUs, with an average score of 54,247. If the CPU and GPU percentiles were the only factor, one might expect a higher combo rank. The fact that the combo sits at the 67th percentile in Downfall suggests that the game’s performance is not solely determined by these two components; other factors such as memory configuration, storage, or the game’s engine characteristics may play a role. Still, the measured FPS data shows that this combo is more than capable of smooth 1080p and 1440p gameplay, and only struggles at 4K Ultra.

The ranking is also informative when compared to the nearest rivals. The RTX 4080 is within 0.1% of the RTX 4080 SUPER in average GPU score, and the CPU is within 0.1% of the Intel Core Ultra 9 285HX. Yet the combo’s rank is 1219th, which implies that many other combos with slightly different components achieve higher FPS in Downfall. This could be due to the game’s age — it released in 2016 — and its relative insensitivity to high-end hardware. The 4K Ultra result of 53 FPS, for instance, suggests that the GPU is the limiting factor, but the combo still outperforms the majority of tested systems.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor from the 8000 series, based on the Zen 4 architecture (codename Dragon Range). It runs at a base clock of 2.50 GHz and a boost clock of 5.40 GHz, with a TDP of 55 W. The CPU includes 64 MB of L3 cache, 1 MB of L2 per core, and 64 KB of L1 per core. It supports DDR5 memory in a dual-channel configuration, providing a memory bandwidth of 83.2 GB/s. The CPU is built on TSMC’s 5 nm process and has 13,140 million transistors across a 2x 71 mm² die.

In synthetic benchmarks, the CPU scores 42,713 points in Cinebench R23 multi-core and 6,030 points in single-core. PassMark results show 51,405 for multithreaded and 3,907 for single-threaded performance. These scores place the CPU in the 95th percentile of all CPUs, with an average benchmark score of 76,212. Its nearest rival, the Intel Core Ultra 9 285HX, scores 76,155 on average, a delta of 0.1% — meaning the 8945HX is essentially tied with it. The AMD EPYC Embedded 8224P and Ryzen Threadripper PRO 9945WX are both 0.4% higher, while the Ryzen 9 9950X3D is 0.6% lower.

In Downfall, the CPU’s contribution is most evident at 1080p, where frame rates are not limited by the GPU. The Low preset hits 287 FPS, and the Medium preset averages 235 FPS. These numbers indicate that the 16-core processor can handle the game’s CPU logic with headroom to spare. The boost clock of 5.40 GHz helps single-threaded performance, which is relevant for a game that may rely on a few fast cores. The 64 MB L3 cache and dual-channel memory bandwidth of 83.2 GB/s provide sufficient data transfer for the game’s assets, but the data does not indicate that the CPU is a bottleneck at any resolution. The consistent frame-rate scaling across resolutions, as discussed earlier, confirms that the GPU is the primary constraint for this combo in Downfall.
