Downfall

# Downfall with AMD Ryzen 9 5900X + AMD Radeon RX 7800 XT

The AMD Ryzen 9 5900X paired with the AMD Radeon RX 7800 XT ranks 1234th out of 3716 tested combos in Downfall, placing it in the upper third of all configurations evaluated. This is a horror title from 2016 that responds well to both strong CPU throughput and substantial GPU memory bandwidth, and the measured frame rates across three resolutions and four quality presets show a system that delivers playable performance at 4K, excellent performance at 1440p, and very high frame rates at 1080p. The combination of a 12-core Zen 3 processor with a 16 GB RDNA 3 graphics card produces a balanced platform where the limiting factor shifts from GPU at 4K to CPU at 1080p, though both components remain capable throughout the tested range.

How This Combo Ranks

The combo's position of 1234 out of 3716 tested configurations means this pairing sits ahead of roughly two-thirds of all tested systems in Downfall. This is a solid result for a mid-to-high-range desktop setup, particularly given that the game was released several years before either component launched. The ranking reflects the combined contribution of both the processor and the graphics card, and the data indicates that neither component is dramatically underperforming relative to its expected contribution.

The AMD Ryzen 9 5900X itself ranks in the 87th percentile among all CPUs tested across the benchmark database, with an average benchmark score of 41376. Its nearest rivals in the overall CPU rankings include the Intel Core Ultra 7 366H with an average score of 41263 (a 0.3% delta), the Intel Core Ultra 7 356H at 41215 (0.4% delta), and the AMD Ryzen AI 5 PRO 440 at 41208 (0.4% delta). The Intel Core i7-14650HX sits slightly ahead at 41576, representing a -0.5% delta from the 5900X's score. These deltas are all within one percent, indicating that the 5900X sits in a tightly clustered performance band where small architectural differences separate competitors.

The Radeon RX 7800 XT, meanwhile, ranks in the 51st percentile among all GPUs, with an average benchmark score of 11627. Its nearest rivals show a wider spread: the NVIDIA GeForce GTX 1660 scores 11680 (-0.5% delta), the AMD Radeon Pro 5500M scores 11528 (0.9% delta), and the NVIDIA Tesla K20c scores 11479 (1.3% delta). The AMD Radeon RX 6500 XT sits above at 11842 (-1.8% delta). These comparisons reveal that while the 7800 XT is ranked near the median of all GPUs in aggregate benchmarks, its real-world performance in Downfall is substantially stronger, as evidenced by the measured frame rates. This discrepancy suggests that Downfall's rendering workload aligns well with the 7800 XT's specific architectural strengths rather than its general-purpose compute capabilities.

GPU Role

The AMD Radeon RX 7800 XT brings 16 GB of GDDR6 memory on a 256-bit bus, yielding a memory bandwidth of 624.1 GB/s. This is a substantial memory subsystem that proves particularly relevant in Downfall, a horror game that tends to load large texture sets and maintain consistent frame pacing during dark, environment-heavy scenes. The GPU's base clock is 1295 MHz, with a boost clock of 2430 MHz and a game clock of 2124 MHz. The memory operates at 2438 MHz, which translates to 19.5 Gbps effective.

The 7800 XT's rendering resources include 3840 shading units, 240 texture mapping units, and 96 raster operation pipelines. The pixel rate is 233.3 GPixel/s and the texture rate is 583.2 GTexel/s, with FP32 performance rated at 37.32 TFLOPS. These specifications indicate a GPU designed for high-throughput rasterization, which is precisely what Downfall's 2016-era engine requires. The card also includes 60 ray tracing cores, though Downfall predates widespread ray tracing adoption and the measured data does not indicate ray tracing workloads being exercised.

At 4K resolution, the GPU becomes the primary performance determinant. The measured frame rates show a clear progression from 53 FPS at Ultra settings to 84 FPS at High, 103 FPS at Medium, and 125 FPS at Low. The substantial jump from Ultra to High (31 FPS) suggests that the Ultra preset includes effects that impose a heavy load on the GPU's shading units and memory bandwidth. The 16 GB VRAM capacity ensures that even at 4K Ultra, memory capacity is unlikely to be a limiting factor; the constraints appear to be computational rather than capacity-related.

Resolution Scaling

The measured FPS data across 1080p, 1440p, and 4K reveals how the system's performance scales with resolution and what that implies about the primary bottleneck. At 1080p, the Low preset delivers 282 FPS, Medium delivers 231 FPS, High delivers 189 FPS, and Ultra delivers 118 FPS. Moving to 1440p, the same settings produce 202 FPS, 165 FPS, 135 FPS, and 85 FPS respectively. At 4K, the numbers drop further to 125 FPS, 103 FPS, 84 FPS, and 53 FPS.

The scaling from 1080p to 1440p shows an average reduction of roughly 28% across all settings, while scaling from 1440p to 4K shows an additional reduction of roughly 38%. The most dramatic single drop occurs at Ultra settings from 1080p (118 FPS) to 1440p (85 FPS), representing a 28% decrease, followed by another 38% decrease at 4K (53 FPS). These scaling patterns are consistent with a GPU-bound scenario at higher resolutions, where the increased pixel count directly impacts the rasterization workload.

At 1080p, the frame rates exceed 200 FPS at Low and Medium settings, which suggests that the CPU is capable of feeding the GPU at high rates. The 5900X's 12 cores and 24 threads, with a base clock of 3.70 GHz and boost clock of 4.80 GHz, provide ample single-thread performance for game logic and draw call submission. The fact that 1080p Low achieves 282 FPS indicates that the CPU is not a limiting factor at lower resolutions, and the GPU has sufficient headroom to render frames as fast as the CPU can issue them.

The resolution scaling data indicates that Downfall is predominantly GPU-limited at 1440p and 4K, while at 1080p the system approaches a more balanced state where both components contribute meaningfully to overall performance. The gap between 1080p and 1440p frame rates is larger than the gap between 1440p and 4K in percentage terms, which is typical for a game where memory bandwidth and fill rate become increasingly important at higher pixel counts.

FAQ

A: At 1080p Medium, the average is 231 FPS with a minimum of 196 and maximum of 266. At 1440p Medium, the average is 165 FPS with a minimum of 140 and maximum of 190. At 4K Medium, the average is 103 FPS with a minimum of 87 and maximum of 118. The min-to-max spread narrows as resolution increases, indicating more consistent frame pacing at higher pixel counts.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across twelve configurations, spanning three resolutions and four quality presets. At 1920x1080, the Low preset achieves an average of 282 FPS, which is the highest measured value in the dataset. The Medium preset at 1080p delivers 231 FPS average, with a minimum of 196 and maximum of 266. The High preset at 1080p produces 189 FPS average, and the Ultra preset drops to 118 FPS average. This progression shows a 58% reduction from Low to Ultra at 1080p, indicating that the Ultra preset imposes significant additional GPU load even at this resolution.

At 2560x1440, the Low preset averages 202 FPS, representing a 28% decrease from the 1080p Low result. The Medium preset at 1440p averages 165 FPS, with a minimum of 140 and maximum of 190, showing a slightly wider variance than the 1080p Medium result. The High preset at 1440p averages 135 FPS, and the Ultra preset averages 85 FPS. The reduction from Low to Ultra at 1440p is 58%, identical to the percentage drop at 1080p, suggesting that the relative cost of each preset is consistent across these two resolutions.

At 3840x2160, the Low preset averages 125 FPS, the Medium preset averages 103 FPS with a minimum of 87 and maximum of 118, the High preset averages 84 FPS, and the Ultra preset averages 53 FPS. The drop from Low to Ultra at 4K is 58%, again matching the pattern seen at lower resolutions. This consistency indicates that the Ultra preset imposes a fixed proportional overhead regardless of resolution, while the absolute frame rates are determined by the pixel count.

The Medium preset is the only one with recorded minimum and maximum FPS values across all resolutions, providing insight into frame pacing. At 1080p, the spread from minimum to maximum is 70 FPS (196 to 266), which narrows to 50 FPS at 1440p (140 to 190) and 31 FPS at 4K (87 to 118). This narrowing suggests that at higher resolutions, the GPU becomes more consistently saturated, reducing the variance in frame delivery times.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, built on TSMC's 7 nm process node. It features a base clock of 3.70 GHz and a boost clock of 4.80 GHz, with a TDP of 105 W. The CPU's cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 64 MB of L3 shared across the chip. The processor supports DDR4 memory in a dual-channel configuration with a memory bandwidth of 51.2 GB/s, and it runs on the AMD Socket AM4 platform with PCIe Gen 4 connectivity.

In Downfall, the CPU's role is most evident at 1080p, where the system achieves 282 FPS at Low settings. This high frame rate indicates that the 5900X can maintain very high draw call throughput and game logic processing. The 3dmark single-thread score of 941 and multi-thread score of 10075 at max threads provide context for the CPU's capability in both lightly-threaded and heavily-threaded workloads. The Cinebench R23 multicore score of 16262 and single-core score of 1527 further confirm strong performance in both scenarios.

The CPU's 87th percentile ranking among all CPUs, with an average benchmark score of 41376, places it comfortably above the median. Its nearest rivals include the Intel Core Ultra 7 366H and Core Ultra 7 356H, both of which are mobile processors that achieve nearly identical average scores. This suggests that the 5900X's desktop-oriented design with higher clocks and more generous power envelope does not provide a significant advantage in aggregate benchmarks, though in gaming workloads like Downfall, the sustained clock behavior of a desktop CPU can be beneficial.

The 5900X's 12 cores and 24 threads are more than sufficient for Downfall, which is a 2016 title that likely does not scale beyond a handful of threads. The processor's single-thread performance, as evidenced by the 3dmark single-thread score of 941 and Geekbench single-core score of 2083, is more relevant for this game's engine. The Passmark single-thread score of 3469 further reinforces that this CPU provides strong single-threaded capability, which is what Downfall's game logic and render thread require.

Settings Recommendations

The measured FPS data provides clear guidance for selecting settings based on target resolution and desired frame rate. At 1080p, all presets deliver average frame rates above 118 FPS, so the recommendation depends on whether the user prioritizes maximum visual quality or maximum frame rate. The High preset at 189 FPS offers an excellent balance, providing strong visual fidelity while maintaining frame rates that exceed the refresh rate of most high-refresh-rate monitors. The Ultra preset at 118 FPS remains smooth and provides the highest quality visuals available in the dataset.

At 1440p, the High preset at 135 FPS is the strongest recommendation. It delivers a substantial improvement over the Medium preset's 165 FPS in visual quality while remaining well above the 60 FPS threshold. The Ultra preset at 85 FPS is also viable for users who prioritize image quality, though the 50 FPS gap between High and Ultra suggests that the Ultra preset includes effects that may not justify the performance cost for all users. The Low preset at 202 FPS is unnecessary at this resolution, as the High preset already provides more than adequate frame rates.

At 4K, the High preset at 84 FPS is the recommended choice for most users. It offers a significant improvement over the Medium preset's 103 FPS in visual quality while maintaining frame rates that are smooth on standard 60 Hz displays and most VRR displays. The Ultra preset at 53 FPS is playable but sits below 60 FPS, which may result in noticeable judder on fixed-refresh displays. The Low preset at 125 FPS is not recommended at 4K, as the visual quality reduction is substantial and the frame rate benefit over High is modest in absolute terms.

Across all resolutions, the Medium preset demonstrates consistent frame pacing, with the only recorded minimum and maximum values in the dataset. At 4K Medium, the minimum of 87 FPS and maximum of 118 FPS indicate that the system maintains a narrow frame time distribution, which is particularly important in a horror game where sudden frame hitches can break immersion. For users who prioritize consistent frame delivery over peak frame rates, the Medium preset at any resolution offers the most predictable performance profile.
