Downfall

The AMD Ryzen 7 5800X paired with the AMD Radeon RX 6750 XT delivers a comprehensive performance profile in Downfall, a horror title from 2016. This analysis examines the measured FPS data across three resolutions and four quality presets, interpreting the results through the lens of the hardware’s specifications and benchmark standings. The CPU, a Zen 3 Vermeer chip with 8 cores and 16 threads, and the GPU, a RDNA 2.0 Navi 22 part with 12 GB of GDDR6 memory, form the basis of this system. The data shows a clear hierarchy of performance that informs optimal settings and reveals the balance between processor and graphics load.

Settings Recommendations

The measured FPS data indicates that the High preset offers the most balanced experience across all tested resolutions. At 1920x1080, the High preset produces an average of 163.6 FPS, which is a substantial drop from the 242.1 FPS seen at Low, but it remains far above the 99.6 FPS of the Ultra preset. The step from Low to High costs roughly 78.5 FPS, while the step from High to Ultra costs 64 FPS, suggesting that High captures most of the visual fidelity without the steep performance penalty of Ultra. At 2560x1440, the High preset averages 113.7 FPS, still comfortably above the 70.2 FPS of Ultra, making it the recommended choice for smooth gameplay. At 3840x2160, High achieves 69.9 FPS, which is playable for a horror title where pacing matters more than twitch reflexes, whereas Ultra drops to 45.7 FPS, a level that may feel less fluid.

For users prioritizing maximum frame rates, the Low preset at 1080p hits 242.1 FPS, but this comes at the cost of visual detail. The Medium preset provides a middle ground, with 198.2 FPS at 1080p, 141.1 FPS at 1440p, and 85.5 FPS at 4K. The data suggests that High is the sweet spot: it delivers 163.6 FPS at 1080p, 113.7 FPS at 1440p, and 69.9 FPS at 4K, all of which are above typical refresh rate thresholds for smooth motion. The Ultra preset, while offering the highest quality, reduces performance by 39% compared to High at 1080p (99.6 vs 163.6 FPS), a trade-off that is difficult to justify given the marginal visual gains in a dark, atmospheric game. Therefore, High is recommended for the best experience per the measured rows, balancing clarity and fluidity across all resolutions.

GPU Role

The AMD Radeon RX 6750 XT is the primary driver of frame rates in Downfall, and its specifications directly explain the measured results. The GPU features 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth, which is ample for a 2016 title even at 4K resolution. The memory clock runs at 2250 MHz, translating to 18 Gbps effective, and this high bandwidth supports the texture-heavy environments typical of horror games. The base clock is 2150 MHz, with a boost clock of 2600 MHz and a game clock of 2495 MHz, providing the computational headroom seen in the FPS numbers.

The GPU’s rendering capabilities are defined by its 2560 shading units, 160 texture mapping units, and 64 ROPs, which produce a pixel rate of 166.4 GPixel/s and a texture rate of 416.0 GTexel/s. These figures correlate with the FPS scaling: at 1080p, the GPU can push 163.6 FPS on High, but as resolution increases to 4K, the pixel fill rate becomes a limiting factor, dropping to 69.9 FPS on the same preset. The FP32 performance of 13.31 TFLOPS is sufficient for the game’s DirectX 12 Ultimate (12_2) API, and the 40 ray tracing cores, while not heavily utilized in this title, add future-proofing. The GPU’s average benchmark score of 35327 places it in the 79th percentile, with rivals like the NVIDIA GeForce RTX 3080 (35787) and AMD Radeon RX 5600M (35264) showing similar aggregate performance, yet the game-specific data reveals that Downfall scales predictably with the GPU’s memory bandwidth and shading capacity.

The VRAM capacity is not a bottleneck here, as even at 4K Ultra, the game runs at 45.7 FPS, indicating that the 12 GB buffer is sufficient; the drop from High to Ultra is more about shader complexity than memory exhaustion. The GPU’s 250 W TDP and dual-slot design are consistent with its performance class, and the PCIe 4.0 x16 interface ensures no bandwidth limitation. Overall, the data shows that the RX 6750 XT is well-matched to Downfall’s engine, with the measured FPS reflecting its mid-to-high-end positioning in the 79th percentile of all GPUs.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across twelve combinations of resolution and settings. At 1920x1080, the Low preset delivers 242.1 FPS, Medium 198.2 FPS, High 163.6 FPS, and Ultra 99.6 FPS. This shows a consistent degradation as quality increases, with the largest single drop occurring from High to Ultra, a loss of 64 FPS. At 2560x1440, the numbers are 172 FPS for Low, 141.1 FPS for Medium, 113.7 FPS for High, and 70.2 FPS for Ultra. The pattern holds, but the absolute values are lower due to the increased pixel count. At 3840x2160, Low still manages 109.2 FPS, Medium 85.5 FPS, High 69.9 FPS, and Ultra drops to 45.7 FPS.

These figures reveal that the system is capable of high refresh rates at 1080p even on High, making it ideal for competitive play if desired. At 1440p, the High preset’s 113.7 FPS is excellent for most displays, while Ultra’s 70.2 FPS remains playable but less smooth. At 4K, the Low preset’s 109.2 FPS is surprising, indicating that the game is not overly demanding at lower settings, but the Ultra preset’s 45.7 FPS is the only sub-60 FPS result in the entire dataset. The data also shows that the gap between Low and Ultra widens with resolution: at 1080p the difference is 142.5 FPS, at 1440p it is 101.8 FPS, and at 4K it is 63.5 FPS. This suggests that the GPU’s fill rate limits the Ultra preset more severely at higher resolutions, while the CPU becomes less relevant as the GPU takes over the workload.

Resolution Scaling

The FPS drop from 1080p to 4K is a clear indicator of where the bottleneck lies. At the Low preset, the average FPS goes from 242.1 at 1080p to 172 at 1440p and finally 109.2 at 4K. This represents a 45% reduction from 1080p to 1440p (242.1 to 172) and a 55% reduction from 1080p to 4K (242.1 to 109.2). At the High preset, the numbers are 163.6, 113.7, and 69.9 FPS, respectively, showing a 31% drop to 1440p and a 57% drop to 4K. The scaling is not linear, which points to the GPU being the primary constraint as resolution increases.

The pixel count quadruples from 1080p to 4K, but the FPS does not quarter, meaning the GPU has some headroom in its memory bandwidth and compute units. For instance, at Low settings, 4K achieves 45% of the 1080p frame rate (109.2/242.1), which is better than the theoretical 25% if it were purely pixel-bound. This indicates that the game’s engine is not fully saturating the GPU at lower settings, allowing the RX 6750 XT’s 432.0 GB/s bandwidth to compensate. At Ultra settings, 4K achieves 46% of the 1080p frame rate (45.7/99.6), suggesting a similar scaling pattern. The consistency across presets implies that the limiting component is the GPU’s shader processing, particularly the 2560 shading units, rather than memory or CPU. The CPU’s role is secondary, as its 8-core, 16-thread configuration with a boost clock of 4.70 GHz provides ample processing power to feed the GPU at all resolutions, but the FPS data clearly shows a GPU-bound scenario at higher pixel counts.

CPU Role

The AMD Ryzen 7 5800X provides the computational foundation for this system, and its specifications align with the measured FPS in Downfall. The CPU features 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.80 GHz and a boost clock of 4.70 GHz. Its cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a 32 MB L3 cache, which is crucial for game logic and physics calculations. The CPU’s benchmark scores are robust: it achieves a Cinebench R23 multi-core score of 23571 and a single-core score of 3327, placing it in the 84th percentile of all CPUs. Its average benchmark score of 27606 is nearly identical to the AMD Ryzen 7 5800 (27535, a 0.3% delta), showing that this processor is a strong performer.

In Downfall, the CPU’s role is to maintain a stable frame pipeline, especially at lower resolutions where the GPU is less stressed. At 1080p Low, the system hits 242.1 FPS, which requires the CPU to process game state updates and draw calls rapidly. The 8-core design with 16 threads ensures that background tasks do not interfere with the main game thread, and the high single-core performance (Geekbench single-core score of 2194) is beneficial for the game’s primary logic. The data shows that the CPU is not a bottleneck at any resolution, as the FPS scaling from 1080p to 4K is consistent with GPU limitations. The CPU’s memory bandwidth of 51.2 GB/s on a dual-channel DDR4 interface is sufficient for this game, and its PCIe Gen 4 support with 20 lanes allows the GPU to communicate without restriction.

The CPU’s 84th percentile ranking versus all CPUs, with a Passmark multithread score of 27732, indicates that it has headroom for more demanding titles, but in Downfall, it operates as a capable partner to the RX 6750 XT. The measured FPS at 4K High (69.9) shows that the CPU can feed the GPU enough data to maintain playable frame rates, while the 1080p results show that it can push over 200 FPS when the GPU allows. The CPU’s TDP of 105 W and 7 nm process node contribute to its efficiency, but the game data is the clearest evidence: the CPU provides a solid platform without constraining the GPU’s performance, making it a balanced match for this horror title.
