Downfall

The AMD Ryzen 7 5700G paired with the AMD Radeon RX 580 delivers a surprisingly playable experience in Downfall, a 2016 horror title that clearly favors raw GPU throughput over CPU muscle. The measured data reveals a system that excels at 1080p, struggles at 4K, and leaves room for interpretation about where the true bottleneck lies.

FAQ

*Q: What is the best resolution and settings combination for this hardware in Downfall?*

A: The 1920x1080 Medium preset, delivering an average of 83.5 FPS, offers the best balance between fluidity and visual fidelity. High at 1080p is also viable at 68.8 FPS, but the drop from Medium to High costs nearly 15 FPS, making Medium the sweet spot.

*Q: Can this combo handle 4K gaming in Downfall?*

A: Barely, and only at the lowest settings. At 3840x2160 with Low settings, the system averages 44.4 FPS, which is borderline playable. High and Medium settings at 4K fall to 30.2 and 36.1 FPS respectively, while Ultra drops to 20.5 FPS, which is not a smooth experience.

Q: How does the CPU compare to its closest rivals in synthetic benchmarks?

A: The Ryzen 7 5700G has an average benchmark score of 25626, placing it in the 83rd percentile of all CPUs. It is nearly identical to the AMD Ryzen 7 6800U, which scores 25706 (a 0.3% difference), and slightly ahead of the Intel Xeon D-2752TER (25532, 0.4% higher) and Intel Core 5 210H (25490, 0.5% higher).

Q: What is the GPU's standing relative to other graphics cards?

A: The RX 580 sits in the 53rd percentile of all GPUs with an average benchmark score of 13559. Its performance is essentially tied with the NVIDIA GeForce GTX 570 (13564, 0% delta) and the NVIDIA GeForce GTX 950 (13549, 0.1% delta), making it a middle-of-the-pack contender.

Q: How does the 5700G's multi-threaded performance compare to its single-threaded performance?

A: The multi-threaded scores are substantially higher. In Cinebench R23, the multicore score is 20755 versus 2930 for single-core, showing a 7x scaling advantage. Similarly, 3DMark shows a peak of 6629 with 16 threads versus 899 for a single thread, indicating strong scaling across its 8 cores and 16 threads.

*Q: Is the 8 GB VRAM on the RX 580 sufficient for Downfall at high resolutions?*

A: The data suggests VRAM capacity is not the primary constraint. The RX 580 has 8 GB of GDDR5 memory with a 256-bit bus and 256.0 GB/s bandwidth. The larger performance drops between 1440p and 4K (e.g., from 49.3 to 30.2 FPS on High) are more indicative of compute or memory bandwidth limits rather than VRAM overflow.

GPU Role

The AMD Radeon RX 580 is the defining component in this pairing for Downfall. With a base clock of 1257 MHz and a boost clock of 1340 MHz, the GPU's performance caps out at 6.175 TFLOPS of FP32 compute. The data shows a clear pattern: as resolution increases, the frame rate collapses, highlighting that the RX 580's fillrate and memory bandwidth are the limiting factors.

At 1080p, the GPU has enough headroom to push frame rates above 100 FPS on Low, but the scaling to 4K is brutal. The jump from 1920x1080 to 2560x1440 on High settings results in a 28% performance loss (68.8 to 49.3 FPS). Moving from 1440p to 4K at High settings costs another 39% of frame rate (49.3 to 30.2 FPS). These diminishing returns point directly at the 256.0 GB/s memory bandwidth and the 193.0 GTexel/s texture rate being overwhelmed at higher pixel counts.

The RX 580's 8 GB of VRAM is adequate for the textures Downfall likely demands, as even at 4K Ultra, the system still renders 20.5 FPS rather than stuttering to a halt. The GPU's DirectX 12 support (12_0) and Vulkan 1.3 compatibility are also relevant, as the game's API usage can influence how efficiently these clocks are utilized. Interestingly, the GPU's Passmark G3D score of 8813 is modest, but its DirectX 11 score of 60 suggests it is well-tuned for legacy rendering paths, which might explain why Low settings at 4K still achieve 44.4 FPS.

Settings Recommendations

The measured data provides a clear hierarchy for optimizing the experience. The 1920x1080 Medium preset is the recommended starting point, averaging 83.5 FPS. This provides a substantial 21% improvement over High settings (68.8 FPS) while retaining a visual quality step above Low. For players seeking maximum fluidity, Low at 1080p yields 100.2 FPS, a 17% gain over Medium, which is ideal for horror titles where quick reactions matter.

At 2560x1440, Medium (60.5 FPS) is the only preset that maintains a 60 FPS average. High drops to 49.3 FPS, which is acceptable for slower-paced horror exploration but not ideal for action sequences. The Ultra preset at 1440p (28.4 FPS) is a non-starter. Moving up to 3840x2160, Low (44.4 FPS) is the only playable option, with Medium (36.1 FPS) and High (30.2 FPS) being borderline cinematic, and Ultra (20.5 FPS) being effectively a slideshow.

The data suggests that the visual difference between Medium and High is not worth the performance penalty at any resolution. The 1080p Medium preset offers the best "experience per frame," as it preserves the GPU's resources for maintaining a stable frame rate in a genre where sudden frame drops can ruin the atmosphere.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its peak performance. Low settings average 100.2 FPS, providing a comfortable margin above 60 FPS. Medium settings drop to 83.5 FPS, which is still excellent. High settings average 68.8 FPS, and Ultra falls to 43.5 FPS. The gap between High and Ultra is the largest single-step drop at this resolution (25.3 FPS), suggesting that Ultra enables expensive effects that the RX 580 cannot handle efficiently.

At 2560x1440, the performance curve becomes steeper. Low averages 73.6 FPS, which is playable. Medium averages 60.5 FPS, right at the playability threshold. High averages 49.3 FPS, which is acceptable for the genre. Ultra plummets to 28.4 FPS, a 53% drop from High, indicating that Ultra settings at 1440p are beyond the GPU's capabilities.

At 3840x2160, the system is clearly overmatched. Low averages 44.4 FPS, which is playable but not smooth. Medium averages 36.1 FPS, and High averages 30.2 FPS, both below the 60 FPS threshold. Ultra averages 20.5 FPS, which is unplayable. The scaling from 1440p to 4K at Low settings (73.6 to 44.4 FPS) represents a 40% reduction, highlighting the immense pixel throughput demand that the RX 580 cannot meet.

How This Combo Ranks

The combination of the Ryzen 7 5700G and RX 580 ranks 1618 out of 1741 tested combos in Downfall. This places it in the bottom 7% of all possible system configurations, which is a stark contrast to the individual component standings. The CPU ranks in the 83rd percentile of all processors, and the GPU ranks in the 53rd percentile of all GPUs, yet their combined performance is poor.

This disparity suggests that either the RX 580 is severely bottlenecking the CPU in this title, or that Downfall has a specific optimization issue with this hardware pairing. The low rank indicates that most other combos tested achieve higher frame rates, likely due to more balanced GPU-CPU pairings. The CPU's high benchmark scores (e.g., 20755 in Cinebench R23 multicore) are rendered irrelevant by the GPU's inability to keep up at higher resolutions, but at 1080p Low, the system shows it can reach 100.2 FPS. The rank likely suffers because the data includes higher-resolution tests where the GPU fails to deliver, dragging the average score down.

CPU Role

The AMD Ryzen 7 5700G is a formidable processor that is not the limiting factor in Downfall. With 8 cores and 16 threads based on the Zen 3 architecture, it operates at a base clock of 3.80 GHz and boosts to 4.60 GHz. The CPU's 16 MB of L3 cache and 51.2 GB/s of dual-channel DDR4 memory bandwidth provide ample resources for game logic and physics.

The benchmark data shows exceptional multi-threaded performance: Cinebench R23 multicore scores 20755, and Passmark's multithread test scores 24419. Single-thread performance is also strong, with Cinebench R23 single-core at 2930. In Downfall, a horror game that likely has modest threading requirements, the CPU is never the bottleneck. The measured FPS at 1080p Low (100.2 FPS) is likely near the game's engine limit for this CPU, but the drop to 68.8 FPS at 1080p High is purely GPU-driven.

The CPU's 65W TDP and 7nm process node (TSMC) allow for sustained boost clocks without thermal throttling, ensuring consistent frame times. The 5700G's integrated Radeon Vega 8 graphics are irrelevant here since the discrete RX 580 handles rendering. The CPU's performance relative to rivals (e.g., 0.5% faster than the Intel Core 5 210H) confirms it is not holding back the system.

Resolution Scaling

The FPS drop from 1080p to 4K is the most revealing metric for bottleneck analysis. At Medium settings, the progression is 83.5 FPS (1080p) → 60.5 FPS (1440p) → 36.1 FPS (4K). This represents a 27.5% drop from 1080p to 1440p, and a 40.3% drop from 1440p to 4K. The scaling is not linear, suggesting the GPU is hitting memory bandwidth limits.

At Low settings, the progression is 100.2 FPS (1080p) → 73.6 FPS (1440p) → 44.4 FPS (4K). The drop from 1080p to 1440p is 26.6%, and from 1440p to 4K is 39.7%. These percentages are remarkably consistent across settings, indicating that the RX 580's fixed memory bandwidth of 256.0 GB/s is the primary constraint.

The pixel count increases by 2.25x from 1080p to 1440p, and by 2.25x from 1440p to 4K. If the GPU were purely fillrate-bound, we would expect a linear FPS drop (e.g., 100.2 / 2.25 = 44.5 FPS at 1440p). Instead, we see 73.6 FPS at 1440p, which is 65% higher than the linear prediction. This indicates that the GPU is not purely fillrate-bound; rather, it is likely limited by the game's draw call overhead or the CPU's ability to feed the GPU. At 4K, the FPS (44.4) is much closer to the linear prediction (73.6 / 2.25 = 32.7 FPS), suggesting the GPU becomes the absolute bottleneck at that resolution. The data implies that at 1080p and 1440p, the system is partially CPU-bound or engine-limited, but at 4K, the RX 580's raw compute is definitively the ceiling.
