Downfall

The AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 5070 delivers a highly capable experience in Downfall, a 2016 horror title that scales predictably with resolution and settings. The data shows a combination that is firmly mainstream in this game’s database, ranking in the 46th percentile of tested combos, with performance that leans heavily on the GPU at higher resolutions while the CPU provides ample headroom. This analysis breaks down exactly how the pairing behaves, where its limits lie, and what the numbers mean for practical play.

Resolution Scaling

The measured FPS data shows a clear and expected trend: performance drops as resolution increases, but the rate of that drop reveals where the bottleneck sits. At 1080p with Low settings, the combo averages 223 FPS. Moving to 1440p Low drops that to 159 FPS, a 29% reduction. At 4K Low, the average falls to 99 FPS, which is a 56% drop from 1080p Low. This scaling pattern is typical for a GPU-bound scenario at lower settings—the render load grows with pixel count, and the graphics card has to work progressively harder.

The story changes when settings are raised. At Ultra settings, the 1080p average is 93 FPS, 1440p drops to 67 FPS (28% lower), and 4K falls to 42 FPS (55% lower than 1080p). Notice that the percentage drop from 1080p to 4K is nearly identical between Low and Ultra (56% vs. 55%). This consistency indicates that resolution scaling is uniform across settings, and the GPU is the primary limiter in both cases. The RTX 5070’s 12 GB of GDDR7 memory and 672.0 GB/s of bandwidth are sufficient to handle the frame buffer at all tested resolutions, but the sheer pixel throughput at 4K cuts the frame rate roughly in half.

The gap between settings at a fixed resolution is also telling. At 1080p, the difference between Low (223 FPS) and Ultra (93 FPS) is 130 FPS, a 58% reduction. At 4K, the same settings gap is 57 FPS (from 99 to 42), a 58% reduction. This parallel scaling means that the game’s settings do not disproportionately burden the GPU at higher resolutions; the performance cost of each setting tier is consistent. For a horror game that relies on atmosphere, the data suggests that playing at 1440p High (107 FPS) or 4K High (66 FPS) is a sensible sweet spot, balancing visual fidelity with smooth frame rates.

How This Combo Ranks

In Downfall, this specific combination of the Ryzen 9 8945HX and RTX 5070 ranks 1570 out of 2928 tested combos. That places it in the lower-middle tier of the database, which is surprising given the individual components’ strong benchmark scores. The CPU sits in the 95th percentile among all CPUs, and the GPU is in the 82nd percentile among all GPUs, yet the combo rank suggests that Downfall does not fully leverage this hardware’s strengths.

The rank implies that many other pairings—likely those with higher-end GPUs or configurations better suited to this game’s engine—outperform this combo. For context, the CPU’s nearest rivals include the Intel Core Ultra 9 285HX, which scores 0.1% higher on average, and the AMD Ryzen 9 9950X3D, which is 0.6% higher. The GPU’s nearest rivals are workstation-class cards like the AMD Radeon Pro 580 (0.1% higher) and the NVIDIA RTX A500 Mobile (2% higher), which are not typical gaming parts. This suggests that the RTX 5070’s gaming performance is competitive with professional cards in synthetic benchmarks, but in Downfall, the combo still lands in the 46th percentile.

What does this mean practically? The combo is not a top-tier performer for this title, but it is far from inadequate. A rank of 1570 out of 2928 means that roughly 54% of tested combos deliver higher frame rates in Downfall. This is likely due to the game’s age—released in 2016—and its engine’s reliance on single-threaded CPU performance or specific GPU features that the RTX 5070’s Blackwell architecture does not prioritize. The data indicates that this pairing is solid for modern titles but does not dominate a legacy horror game.

GPU Role

The NVIDIA GeForce RTX 5070 is the primary driver of frame rates in Downfall, as evidenced by the resolution scaling data. Its specifications include 12 GB of GDDR7 memory on a 192-bit bus, yielding 672.0 GB/s of bandwidth. The base clock is 2325 MHz with a boost clock of 2512 MHz, and the card houses 6144 shading units, 192 texture mapping units, and 80 raster output pipelines. These figures translate to a pixel rate of 201.0 GPixel/s and a texture rate of 482.3 GTexel/s, which are more than adequate for a game from 2016.

The VRAM capacity is not a limiting factor at any of the tested settings. Even at 4K Ultra, where the average FPS drops to 42, the 12 GB frame buffer is sufficient; the performance drop is due to compute load, not memory exhaustion. The GPU’s FP32 throughput of 30.87 TFLOPS is high, and the 48 RT cores and 192 tensor cores are present but largely unused in a non-ray-traced title like Downfall. The data shows that the GPU’s raw rasterization performance is what matters here, and it scales predictably with resolution and settings.

The RTX 5070’s average benchmark score of 40377 places it in the 82nd percentile of all GPUs, with nearest rivals like the AMD Radeon Pro 580 (40318) and AMD Radeon Pro WX 7100 (40063) being within 1% either way. This indicates that the card’s synthetic performance is consistent, but its real-world gaming results in Downfall are moderate. The measured FPS at 1080p High (149 FPS) and 1440p High (107 FPS) are respectable, but the 4K Ultra result of 42 FPS is below the 60 FPS threshold that many players consider the minimum for smooth gameplay. The GPU is clearly the bottleneck at 4K, as the CPU has ample headroom.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings. At 1920x1080, the combo achieves 223 FPS on Low, 182 FPS on Medium (with a min of 155 and max of 210), 149 FPS on High, and 93 FPS on Ultra. The Medium setting is the only one with recorded min/max values, showing a 55 FPS spread, which indicates some frame pacing variability but no severe stuttering. The 1080p numbers are all above 90 FPS, making this resolution ideal for high-refresh-rate monitors.

At 2560x1440, performance remains strong: 159 FPS on Low, 130 FPS on Medium (min 111, max 150), 107 FPS on High, and 67 FPS on Ultra. The drop from 1080p to 1440p is roughly 29% across all settings, which is consistent with the increased pixel count. The 1440p Ultra result of 67 FPS is playable, but the High setting at 107 FPS offers a better balance for most users. The Medium setting’s min of 111 FPS ensures that even the worst-case frame times stay well above 60 FPS.

At 3840x2160, the GPU is heavily taxed: 99 FPS on Low, 81 FPS on Medium (min 69, max 93), 66 FPS on High, and 42 FPS on Ultra. The 4K High result of 66 FPS is borderline playable, while 4K Ultra at 42 FPS is not ideal for a horror game that benefits from smooth motion. The Medium setting’s min of 69 FPS is noteworthy—it stays above 60 FPS even in the worst case, making 4K Medium the most reliable choice for a locked 60 FPS experience. The data clearly shows that 4K Ultra is the only configuration that dips below 60 FPS, and it does so by a significant margin.

FAQ

A: It ranks 1570 out of 2928 combos, placing it in the 46th percentile. This is lower than the CPU’s 95th percentile and GPU’s 82nd percentile, suggesting that Downfall does not fully utilize the hardware’s strengths.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture, codenamed Dragon Range. It has a base clock of 2.50 GHz and a boost clock of 5.40 GHz, with 64 MB of L3 cache. The CPU’s benchmark scores are impressive: a Cinebench R23 multi-core score of 42713 and a single-core score of 6030, placing it in the 95th percentile of all CPUs. Its average benchmark score of 76212 is nearly identical to its nearest rival, the Intel Core Ultra 9 285HX, which scores 76155 (0.1% higher).

In Downfall, the CPU’s role is secondary to the GPU. The game, released in 2016, does not require 16 cores or 32 threads; it is unlikely to scale beyond a few threads. The CPU’s single-core performance, as evidenced by the Cinebench R23 single-core score of 6030, is more relevant, and it is more than sufficient to feed the RTX 5070. The measured FPS data shows no signs of CPU throttling: at 1080p Low, the combo hits 223 FPS, which is a high frame rate that would expose CPU limits if they existed. The fact that the FPS scales consistently with resolution and settings indicates that the CPU is not a bottleneck at any point.

The CPU’s 55 W TDP and dual-channel DDR5 memory support (83.2 GB/s bandwidth) are adequate for gaming, though the memory bandwidth is modest compared to the GPU’s 672.0 GB/s. The 5 nm process node and 13,140 million transistors give it a performance edge, but in a horror game like Downfall, the CPU’s massive multi-core capability is largely unused. The data suggests that a less powerful CPU could achieve similar frame rates, but the 8945HX ensures there is no risk of CPU-induced stuttering or frame drops, even in the most demanding scenes. For this title, the CPU is a silent partner—it does its job without ever becoming the limiting factor.
