Downfall

# Downfall with AMD Ryzen 5 3600 + NVIDIA GeForce RTX 5090

This combination pairs a 2019 mainstream six-core CPU with NVIDIA's flagship 2025 GPU, creating an intriguing imbalance for a 2016 horror title. The measured FPS data reveals a system where the GPU is rarely the limiting factor, even at 4K, while the CPU's single-thread performance appears to cap frame rates in ways that shape the entire experience. The RTX 5090 sits in the 92nd percentile of all GPUs, while the Ryzen 5 3600 ranks in the 71st percentile of CPUs, and the data shows exactly how that gap manifests in Downfall's benchmark results.

Resolution Scaling

The FPS drop from 1080p to 4K is surprisingly modest for a GPU as powerful as the RTX 5090. At High settings, the average frame rate falls from 248 FPS at 1920x1080 to 217 FPS at 2560x1440, then to 135 FPS at 3840x2160 — a total decline of 45.6% from 1080p to 4K. For most GPU-bound scenarios, a flagship card would exhibit a steeper curve, but here the scaling suggests something else is at play.

At Low settings, the trend is even more revealing: 286 FPS at 1080p, 256 FPS at 1440p, and 201 FPS at 4K. The drop from 1440p to 4K is only 21.5%, which is remarkably gentle. This pattern indicates that even at the lowest settings, the CPU is beginning to constrain the system — the GPU has headroom to spare, but the Ryzen 5 3600 cannot feed it frames fast enough to push higher.

The Medium preset tells a similar story with more granularity. From 1080p (266 FPS) to 1440p (238 FPS), the loss is 10.5%; from 1440p to 4K (164 FPS), the loss jumps to 31.1%. This nonlinear scaling hints that at lower resolutions, the CPU bottleneck is more pronounced, while at 4K, the GPU workload finally becomes substantial enough to shift the balance.

Ultra settings produce the most dramatic resolution scaling: 190 FPS at 1080p, 135 FPS at 1440p, and 84 FPS at 4K. Here, the 4K figure represents a 55.8% drop from 1080p, indicating that at maximum quality, the GPU's rendering workload becomes the dominant constraint. This is the only preset where the resolution curve resembles what one would expect from a GPU-bound title.

What does this imply? The data suggests that Downfall is not particularly demanding on modern hardware — a 2016 horror game running at 84 FPS on Ultra 4K with a 575W GPU is hardly a stress test. The CPU's 3.60 GHz base clock and 4.20 GHz boost clock appear adequate for most scenarios, but the single-thread benchmark scores (696 in 3dmark single thread, 214 in Cinebench R15 single core) hint at the ceiling that caps high-refresh-rate performance.

GPU Role

The RTX 5090 brings overwhelming specifications to this pairing: 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth, with a boost clock of 2407 MHz. Its 21760 shading units and 104.8 TFLOPS of FP32 compute are far beyond what a 2016 horror title could reasonably demand. The GPU's PassMark G3D score of 39650 places it in the 92nd percentile of all GPUs, and its average benchmark score of 79842 puts it within 0.3% of the NVIDIA Tesla P100 PCIe 16 GB — a comparison that seems almost absurd given the generational gap.

In Downfall, the GPU's role is primarily defined by what it does not do: it does not become the bottleneck until Ultra settings at 4K. At every other resolution and preset combination, the frame rates exceed 135 FPS, which suggests the RTX 5090 is operating well below its potential. The 32 GB VRAM is almost certainly irrelevant here — Downfall's textures and geometry from 2016 would struggle to consume even a fraction of that capacity, and the memory bandwidth of 1.79 TB/s is likely never fully utilized.

The GPU's clock behavior at 2017 MHz base and 2407 MHz boost indicates it can sustain high frequencies, but the measured FPS data shows these clocks are not being stressed. At 1080p Low, the system produces 286 FPS — impressive, but for a card with 104.8 TFLOPS, this could be interpreted as the CPU holding it back. The GPU's PassMark DirectX 12 score of 185 and DirectX 11 score of 341 suggest strong API support, yet the game's age likely means it uses older rendering paths that cannot take full advantage of Blackwell 2.0 architecture.

What the data makes clear is that the RTX 5090 is not the determining component in most of these measurements. Its role becomes significant only at 4K Ultra, where the 84 FPS average reflects genuine GPU workload. At lower settings, the GPU is effectively waiting for the CPU to supply draw calls and game logic — a classic pairing of a hyper-fast graphics card with a processor that simply cannot keep pace.

CPU Role

The AMD Ryzen 5 3600 is a 6-core, 12-thread processor based on Zen 2 architecture, built on TSMC's 7 nm process. With a base clock of 3.60 GHz and boost clock of 4.20 GHz, it was a solid mainstream choice at its 2019 release, and its 32 MB of shared L3 cache provides reasonable data locality for gaming workloads. Its PassMark multithread score of 17700 and Cinebench R23 multicore score of 15045 indicate competent multi-threaded performance, but the single-thread metrics are more telling for this analysis.

The 3dmark single-thread score of 696 and Cinebench R23 single-core score of 2124 reveal the CPU's Achilles' heel. Downfall, as a horror title from 2016, likely relies heavily on single-threaded game logic — physics, AI, and rendering commands that cannot be easily parallelized. The CPU's 71st percentile ranking among all CPUs, with an average benchmark score of 17035, places it near rivals like the Intel Core i7-1260P (0.2% faster) and Intel Core i5-11400 (0.2% slower), but these comparisons reflect general compute, not the specific demands of this game.

The data shows a clear pattern: as resolution decreases, the CPU's influence on frame rates increases. At 1080p Low, the system hits 286 FPS — likely near the CPU's maximum frame generation capability. At 4K Ultra, the CPU has breathing room because the GPU takes longer to render each frame, allowing the processor to keep up with draw calls and physics updates. The 84 FPS at 4K Ultra is more likely GPU-limited, while the 286 FPS at 1080p Low is almost certainly CPU-limited.

The CPU's 65W TDP and 3,800 million transistors on a 74 mm² die suggest it was designed for efficiency rather than raw throughput, and in Downfall, this translates to a ceiling around 286 FPS at best. The memory bandwidth of 51.2 GB/s (DDR4 dual-channel) could also factor into the bottleneck — at high frame rates, the CPU must feed data to the GPU quickly, and this bandwidth might not suffice for the RTX 5090's appetite.

FAQ

Q: Is the Ryzen 5 3600 bottlenecking the RTX 5090 in Downfall?

A: Yes, particularly at lower resolutions and settings. At 1080p Low, the system achieves 286 FPS, which appears to be a CPU-imposed ceiling. The GPU's enormous compute capacity (104.8 TFLOPS) is not fully utilized until 4K Ultra settings, where the 84 FPS average suggests the GPU becomes the limiting component.

Q: What is the best resolution to play Downfall with this combo?

A: The data shows diminishing returns below 1440p. At High settings, 1440p delivers 217 FPS compared to 248 FPS at 1080p — a 12.5% drop for a significant resolution increase. At 4K High, the 135 FPS average is still highly playable and represents a 37.7% drop from 1440p.

Q: How does the RTX 5090 compare to its nearest rivals in this game?

A: The GPU's average benchmark score of 79842 is 0.3% above the NVIDIA Tesla P100 PCIe 16 GB and 0.6% above the Tesla P100 PCIe 12 GB, while being 1.1% ahead of the AMD Radeon RX 6850M XT. The AMD Radeon Pro Vega 64X is 1.4% faster in average score.

Q: Does the 32 GB VRAM matter for Downfall?

A: The measured data does not indicate VRAM capacity as a limiting factor. Downfall, released in 2016, would not plausibly require more than a fraction of 32 GB, and the GPU's 1.79 TB/s bandwidth is never stressed based on the FPS results.

Q: What FPS can I expect at 4K Ultra settings?

A: The measured average is 84 FPS. This is the lowest result across all tested configurations, but it remains above the 60 FPS threshold commonly considered smooth for horror titles, where slower pacing often benefits from atmospheric tension.

Q: How does the CPU's single-thread performance affect results?

A: The Ryzen 5 3600's 3dmark single-thread score of 696 and Cinebench R23 single-core score of 2124 appear to cap frame rates around 286 FPS at 1080p Low. Higher resolutions give the CPU more time per frame, which is why 4K Ultra at 84 FPS does not exhibit the same bottleneck.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates across all settings. Low settings yield an average of 286 FPS, Medium achieves 266 FPS with a minimum of 226 and maximum of 306, High reaches 248 FPS, and Ultra drops to 190 FPS. The spread from Low to Ultra is 96 FPS, indicating that settings have a substantial impact at this resolution, though even the lowest value remains well above typical display refresh rates.

Moving to 2560x1440, the averages compress somewhat. Low settings deliver 256 FPS, Medium produces 238 FPS with a range of 202 to 274, High reaches 217 FPS, and Ultra falls to 135 FPS. The gap between Low and Ultra narrows to 121 FPS, but the Ultra preset shows a more pronounced drop — 82 FPS below Medium — suggesting that certain Ultra effects are particularly demanding on the GPU.

At 3840x2160, the hierarchy shifts. Low settings average 201 FPS, Medium achieves 164 FPS with a minimum of 140 and maximum of 189, High produces 135 FPS, and Ultra drops significantly to 84 FPS. The Low-to-Ultra spread of 117 FPS is similar to 1440p, but the absolute values are lower across the board. Notably, Ultra at 4K is less than half the frame rate of Low at 1080p (84 vs. 286 FPS), illustrating how resolution and settings compound their effects.

The Medium preset is the only one with complete min/max data across all resolutions. At 1080p, the range is 226 to 306 FPS (an 80 FPS spread); at 1440p, 202 to 274 FPS (72 FPS spread); and at 4K, 140 to 189 FPS (49 FPS spread). This narrowing range at higher resolutions suggests that frame time consistency improves when the GPU is more heavily loaded, reducing the CPU-induced stutter that can occur at very high frame rates.

Settings Recommendations

The measured data provides clear guidance for optimizing the experience. At any resolution, the Medium preset offers the best balance of visual quality and performance, with the only complete min/max data showing stable frame delivery. At 4K, Medium's 164 FPS average represents a 95.2% improvement over Ultra's 84 FPS, while the visual difference between Medium and Ultra in a 2016 horror game is likely minimal given the age of the assets.

For players prioritizing maximum smoothness, Low settings at 1440p (256 FPS) or 1080p (286 FPS) would be the choice, but these frame rates exceed the refresh rate of most monitors, making the extra frames imperceptible. High settings at 1440p (217 FPS) or 4K (135 FPS) provide a more sensible compromise — the 4K High result is particularly compelling, offering a 60.7% improvement over Ultra while maintaining resolutions that showcase the GPU's capabilities.

Ultra settings are difficult to recommend based on the data. At 4K, the 84 FPS average is playable but represents a substantial performance cost. At 1440p (135 FPS) and 1080p (190 FPS), Ultra is more viable, but the question becomes whether the visual enhancements justify the frame rate reductions. Given that this is a horror game where atmospheric effects and lighting are crucial, Ultra might be worth considering at 1440p, where 135 FPS remains fluid. However, the 31.1% drop from Medium to Ultra at 4K (164 to 84 FPS) suggests that Ultra's additional effects are disproportionately expensive at higher resolutions.

The data also reveals that the CPU bottleneck at lower settings means the GPU is underutilized. If the goal is to maximize visual quality without sacrificing smoothness, High settings at 1440p (217 FPS) or 4K (135 FPS) appear optimal. These configurations keep the GPU sufficiently loaded to avoid CPU-induced frame pacing issues while delivering frame rates that exceed the needs of most displays.

How This Combo Ranks

Among 3,716 tested combinations, this pairing of AMD Ryzen 5 3600 and NVIDIA GeForce RTX 5090 achieves a rank of 344 in Downfall, placing it in the top 9.3% of all tested systems. This is a strong showing, though perhaps not as dominant as the GPU's 92nd percentile ranking might suggest. The CPU's 71st percentile ranking tempers the overall result, confirming that the processor is the weak link in this pairing.

The rank of 344 means that 3,372 other combinations performed better in this game. Given the RTX 5090's position as the flagship of its generation, one might expect a higher placement, but the Ryzen 5 3600's age (released in 2019) and its modest single-thread performance hold back the system. The CPU's nearest rivals in average benchmark score — the Intel Core i7-1260P (0.2% faster), Intel Core i5-11400 (0.2% slower), and AMD EPYC 7573X (0.2% slower) — suggest that the CPU is competitive with mid-range mobile and desktop chips from later years, but none of these would be considered top-tier for gaming in 2025.

The 344th rank out of 3,716 combos indicates that this system outperforms the vast majority of tested configurations, which makes sense given the GPU's raw power. The data implies that upgrading the CPU to a newer, higher-clocked model would likely improve the ranking substantially, particularly at lower resolutions where the current bottleneck is most evident. However, the measured FPS values show that at 4K Ultra, the system still delivers 84 FPS — a playable result that many older or less powerful systems could not achieve.

The rank also contextualizes the GPU's performance. The RTX 5090's average benchmark score of 79842 places it just 0.3% above the Tesla P100 PCIe 16 GB, but in Downfall, the combination's rank suggests that the GPU is not the primary determinant of success. A system with a stronger CPU and a slightly less powerful GPU might rank higher, highlighting the importance of balanced configurations even in a GPU-centric benchmark database.
