Downfall

The AMD Ryzen 5 5500 and Radeon RX 7900 XT pairing in Downfall delivers a performance curve that clearly separates the CPU’s raw throughput from the GPU’s massive rendering headroom. The data shows a system that is heavily GPU-bound at 4K, but which transitions into a more balanced—and eventually CPU-limited—state as resolution drops. For a horror title built on atmospheric tension, the ability to maintain high frame rates across all settings is significant, though the gap between Low and Ultra at 4K reveals where the graphical load truly lies.

Resolution Scaling

The frame rate trajectory from 1080p to 4K is steep and instructive. At 1920x1080 with Low settings, the combo produces 333.4 FPS, which is an exceptional figure that indicates the GPU is barely breaking a sweat. Moving to 2560x1440 Low drops that to 239.9 FPS, a 28% reduction, and at 3840x2160 Low the average falls to 151.7 FPS, a further 37% decline. This pattern shows that even at the lowest settings, the pixel throughput demand of 4K is substantial, cutting performance by more than half compared to 1080p.

The scaling becomes more pronounced at higher settings. At High settings, the drop from 1080p (224.5 FPS) to 1440p (160.2 FPS) is 29%, and the jump to 4K (98.7 FPS) represents a 56% loss from 1080p. Ultra settings show the most extreme scaling: 140.5 FPS at 1080p, 103.9 FPS at 1440p, and 64.6 FPS at 4K. The 4K Ultra result is less than half of the 1080p Ultra figure, demonstrating that the RX 7900 XT’s shading units and memory bandwidth are being pushed to their limits by the combination of high resolution and maximal graphical fidelity. Notably, the difference between Medium and High at any resolution is smaller than the jump from High to Ultra, suggesting that Ultra settings include a particularly demanding set of effects.

CPU Role

The Ryzen 5 5500 is a 6-core, 12-thread processor based on the Zen 3 architecture, with a base clock of 3.60 GHz and a boost clock of 4.20 GHz. Its 16 MB of L3 cache is shared across the cores, and the dual-channel DDR4 memory support provides 51.2 GB/s of bandwidth. In Downfall, the CPU’s role becomes most apparent at lower resolutions where the GPU can render frames faster than the processor can feed them. The 333.4 FPS result at 1080p Low is a strong indicator that the CPU is capable of sustaining very high frame rates, but it also represents a practical ceiling for this combination.

Benchmark data places the 5500 in the 79th percentile of all CPUs, with an average score of 20875. Its nearest rival, the Intel Core i5-12500, scores 20897, a delta of -0.1%, meaning the two are effectively tied in synthetic workloads. The 5500’s single-thread performance, as reflected in a 3dmark_single_thread score of 836, is modest compared to its multi-threaded results, which is typical for a chip in this class. For Downfall, a horror game that likely relies on a few primary threads for game logic and AI, the 5500’s 12 threads provide enough headroom to avoid bottlenecking the GPU at 1440p and above, but the 1080p Low result suggests that the CPU is the limiting factor in that specific scenario.

GPU Role

The Radeon RX 7900 XT is the dominant component in this pairing. With 20 GB of GDDR6 memory on a 320-bit bus, it achieves 800.0 GB/s of bandwidth, which is critical for high-resolution textures. Its 5376 shading units, 336 texture mapping units, and 192 raster operation processors provide substantial raw compute power. The boost clock of 2394 MHz and game clock of 2025 MHz are high for the RDNA 3.0 architecture, and the 5 nm process node from TSMC allows for a transistor density of 109.1M per mm² across 57,700 million transistors.

The GPU’s percentile ranking of 82nd among all GPUs, with an average benchmark score of 38358, confirms its high-end status. Its nearest rival in synthetic tests is the NVIDIA GeForce RTX 5080 Mobile, which scores 38349, a delta of 0%. This indicates that the 7900 XT’s desktop-class performance is comparable to a top-tier mobile part, though the desktop card’s 300 W TDP and dual-slot cooler suggest it is designed for sustained heavy loads. In Downfall, the GPU’s strength is most evident at 4K Ultra, where it still manages 64.6 FPS—a playable result for a horror title—while the CPU’s limitations become less relevant as the resolution increases.

Measured FPS Breakdown

At 1920x1080, the results are consistently high. Low settings yield 333.4 FPS, Medium drops to 274.6 FPS, High follows at 224.5 FPS, and Ultra brings the average down to 140.5 FPS. The step from High to Ultra is the largest single drop at 37%, which indicates that Ultra settings introduce a significant computational burden. Even at the most demanding 1080p preset, the frame rate remains far above the refresh rate of most monitors, making this resolution suitable for competitive play if the game’s horror atmosphere allows for it.

Moving to 2560x1440, the frame rates remain impressive. Low produces 239.9 FPS, Medium 196.6 FPS, High 160.2 FPS, and Ultra 103.9 FPS. The pattern is consistent with 1080p, but the absolute numbers are lower, showing that the GPU is now working harder. The 1440p Ultra result of 103.9 FPS is still smooth, and the gap between Low and Ultra is 57%, which is narrower than at 1080p, suggesting that the CPU is beginning to play a larger role in limiting performance at lower settings.

At 3840x2160, the GPU takes full control. Low settings average 151.7 FPS, Medium 122.1 FPS, High 98.7 FPS, and Ultra 64.6 FPS. The 4K Low result is particularly telling: it is higher than the 1080p Ultra figure, which shows that the GPU has ample headroom at lower settings but is constrained by the sheer number of pixels. The Ultra result of 64.6 FPS is the only one below 60 FPS in the entire dataset, and it represents the worst-case scenario for this combo. The scaling from Low to Ultra at 4K is a 57% reduction, mirroring the 1440p pattern, which reinforces that the GPU is the primary bottleneck at this resolution.

How This Combo Ranks

In the broader database of tested combinations, this pairing ranks 365th out of 1741 combos for Downfall. This places it in the top 21% of all tested systems, which is a strong showing given the CPU’s mid-range status. The rank reflects a balance between the 5500’s modest multi-threaded performance and the 7900 XT’s top-tier GPU capabilities. The CPU’s percentile of 79th is notably lower than the GPU’s 82nd, indicating that the processor is the weaker link in this pairing.

Compared to other combos, the 5500’s synthetic scores are virtually identical to the Intel Core i5-12500, which means that any performance difference in Downfall would come from the GPU rather than the CPU. The 7900 XT’s nearest rival, the RTX 5080 Mobile, has the same average score, suggesting that this desktop GPU is roughly equivalent to a high-end mobile part in raw compute. The 365th rank is likely driven by the CPU’s inability to fully saturate the GPU at lower resolutions, but the high absolute frame rates mean that real-world gameplay is rarely impacted.

FAQ

*Q: Is this combo capable of running Downfall at 4K without issues?*

A: Yes, at 4K High settings the average frame rate is 98.7 FPS, which is well above the 60 FPS threshold for smooth play. Even at 4K Ultra, the combo produces 64.6 FPS, which is playable for a horror title that does not require fast reaction times.

Q: What is the biggest performance gap between settings?

A: The largest single drop occurs from High to Ultra at 1080p, where the average frame rate falls from 224.5 FPS to 140.5 FPS, a 37% reduction. This suggests Ultra settings include particularly demanding effects.

Q: Is the CPU or GPU the limiting factor in this game?

A: At 4K, the GPU is clearly the limiting factor, as frame rates scale directly with resolution. At 1080p Low, the CPU appears to be the bottleneck, as the 333.4 FPS result is likely near the maximum the Ryzen 5 5500 can sustain.

Q: How does the Ryzen 5 5500 compare to its closest rival?

A: The Ryzen 5 5500 has an average benchmark score of 20875, which is 0.1% lower than the Intel Core i5-12500’s 20897. This means they are effectively tied in synthetic performance.

*Q: What is the best resolution for this combo in Downfall?*

A: The 1440p results offer the best balance, with High settings at 160.2 FPS and Ultra at 103.9 FPS. This resolution takes advantage of the GPU’s power while keeping frame rates high.

Q: Does the GPU’s 20 GB of VRAM matter for this game?

A: Given the game’s 2016 release date, the 20 GB of VRAM is far more than necessary, but the 800.0 GB/s bandwidth ensures that high-resolution textures at 4K load quickly and stutter-free.
