Downfall

Downfall’s benchmark data for the AMD Ryzen 7 5700X3D paired with the AMD Radeon RX 570 reveals a configuration that is heavily constrained by the graphics card at higher resolutions, yet surprisingly capable at 1080p. The measured frame rates show a clear narrative: this is a 1080p-oriented setup where the aging Polaris GPU is the primary bottleneck, while the powerful Zen 3 processor waits in the wings. The data indicates that users should prioritize resolution and preset choices carefully to achieve a playable experience in this horror title.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 produces a dramatic and predictable collapse in frame rates, underscoring the GPU-bound nature of Downfall at higher resolutions. At High settings, the average frame rate drops from 62 FPS at 1080p to 44 FPS at 1440p, a 29% reduction. Moving further to 4K, the average plummets to 27 FPS, which represents a 56% drop from the 1080p baseline. This steep decline is a classic indicator that the AMD Radeon RX 570’s rendering capabilities are being saturated as pixel count increases.

The scaling pattern becomes even more telling when examining the Low preset. At 1920x1080, the system achieves a comfortable 92 FPS. At 2560x1440, this falls to 66 FPS, and at 3840x2160, it drops to 41 FPS. The fact that even the lowest settings cannot maintain 60 FPS at 1440p suggests that the RX 570’s raw throughput, rather than its memory subsystem or driver overhead, is the limiting factor. The GPU’s 224.0 GB/s memory bandwidth and 5.095 TFLOPS of FP32 performance are simply insufficient to feed the display at higher pixel densities.

Interestingly, the scaling from 1440p to 4K is less severe than from 1080p to 1440p in percentage terms. At High settings, the drop from 44 FPS to 27 FPS is a 38.6% reduction, while the 1080p to 1440p drop is 29%. This non-linear behavior hints that at 4K, the system is already so far below the refresh rate threshold that other bottlenecks, such as draw call submission or CPU overhead, begin to play a minor role. However, the CPU data suggests this is unlikely, as the Ryzen 7 5700X3D’s multi-threaded performance is far above what Downfall requires.

The data clearly shows that the limiting component shifts with resolution. At 1080p, the CPU has enough headroom to push the GPU to its maximum, as evidenced by the 92 FPS Low preset result. At 4K, the GPU is unequivocally the bottleneck, with the Ultra preset managing only 17 FPS. The takeaway is that users must treat this as a 1080p-centric configuration; any attempt to run at 4K will result in a slideshow, regardless of settings.

FAQ

Q: What is the best resolution for this CPU and GPU combo in Downfall?

A: The measured data shows that 1920x1080 is the only resolution where the system consistently exceeds 60 FPS. At Medium settings, it achieves 75 FPS, and at High settings, 62 FPS. At 2560x1440, the best average is 66 FPS on Low, which drops below 60 on Medium. At 3840x2160, all presets fall below 41 FPS, making it unsuitable for smooth gameplay.

Q: How does the RX 570 compare to its nearest rivals in general benchmarks?

A: The RX 570’s average benchmark score is 28,766, placing it in the 74th percentile of all GPUs. Its nearest rival, the AMD Radeon RX 6800M, scores 28,874, which is a 0.4% difference. The AMD Radeon RX 470 is 0.8% higher, while the NVIDIA Quadro RTX 8000 is 1.2% lower. These differences are negligible in real-world terms.

Q: Is the Ryzen 7 5700X3D a bottleneck for the RX 570 in Downfall?

A: No. The CPU’s multi-threaded benchmark scores, such as 22,366 in Cinebench R23 and 26,318 in Passmark, are far higher than what this game would demand. The frame rate scaling with resolution confirms the GPU is the limiting factor at 1440p and 4K.

Q: What is the expected frame rate at 1080p with Ultra settings?

A: The measured average FPS for the Ultra preset at 1920x1080 is 39 FPS. This is the lowest average among the 1080p presets, indicating that the RX 570 struggles with the highest visual quality settings.

Q: Does the 4 GB VRAM on the RX 570 affect performance in Downfall?

A: The data does not explicitly measure VRAM usage, but the 4 GB GDDR5 memory with a 256-bit bus provides 224.0 GB/s of bandwidth. Given that the High preset at 4K produces 27 FPS and Ultra produces 17 FPS, it is plausible that memory capacity or bandwidth contributes to the severe performance drop at higher resolutions.

Q: How does the CPU’s single-thread performance influence the game?

A: The Ryzen 7 5700X3D has a single-thread score of 804 in 3DMark and 2,970 in Passmark. These are respectable figures, but the game’s frame rates are predominantly GPU-limited, so the CPU’s single-thread strength is not the main factor in the measured results.

GPU Role

The AMD Radeon RX 570 is the undisputed performance ceiling in this configuration. Built on the 14 nm Polaris 20 chip with GCN 4.0 architecture, it operates at a base clock of 1168 MHz and a boost clock of 1244 MHz. The GPU’s 2048 shading units and 32 ROPs deliver a pixel rate of 39.81 GPixel/s and a texture rate of 159.2 GTexel/s. These specifications translate into real-world results that are firmly in the entry-level to mid-range category for modern titles.

In Downfall, the GPU’s role is most evident when examining the frame rate deltas between presets at the same resolution. At 1080p, moving from Low to Medium reduces the average from 92 FPS to 75 FPS, a drop of 18.5%. Increasing to High brings it down to 62 FPS, and Ultra further reduces it to 39 FPS. This consistent degradation across settings indicates that the GPU’s shader and texture units are being progressively loaded, with no sign of CPU intervention.

The 4 GB of GDDR5 memory is a critical specification for this test. At 4K, the Ultra preset’s 17 FPS average suggests that the memory bus is saturated or that the capacity is insufficient for the high-resolution textures. The 256-bit bus width provides 224.0 GB/s of bandwidth, which is adequate for 1080p but likely strained at 1440p and above. The GPU’s 74th percentile ranking among all GPUs, with an average benchmark score of 28,766, places it slightly below the RX 6800M but above the RX 470 in synthetic tests.

The GPU’s power envelope, with a 150 W TDP and a suggested 450 W PSU, confirms its mid-range positioning. The measured results in Downfall show that the RX 570 is best suited for 1080p gaming, where it can deliver playable frame rates on Medium to High settings. At higher resolutions, the GPU’s architectural age becomes apparent, as even the Low preset fails to reach 60 FPS at 1440p.

Measured FPS Breakdown

At 1920x1080, the configuration delivers its best performance. The Low preset averages 92 FPS, which is the highest measured result across all resolutions and settings. Medium settings average 75 FPS, with a minimum of 64 FPS and a maximum of 86 FPS, indicating smooth gameplay with minor fluctuations. High settings average 62 FPS, which is still playable but closer to the 60 FPS threshold. Ultra settings drop to an average of 39 FPS, which is noticeably less fluid and suggests the GPU is overburdened.

Moving to 2560x1440, the frame rates decline significantly. Low settings average 66 FPS, which is the only preset at this resolution to exceed 60 FPS. Medium settings average 54 FPS, with a minimum of 46 FPS and a maximum of 62 FPS, showing more variance and potential stutter. High settings average 44 FPS, and Ultra drops to 28 FPS. These numbers indicate that 1440p is only viable with the lowest settings for a consistent experience.

At 3840x2160, the results are largely unplayable. Low settings average 41 FPS, which is below the 60 FPS target. Medium settings average 33 FPS, with a minimum of 28 FPS and a maximum of 38 FPS. High settings average 27 FPS, and Ultra settings plummet to 17 FPS. The 4K data strongly suggests that this GPU cannot handle the resolution, regardless of how much visual quality is sacrificed.

The measured data also includes specific minimum and maximum values for the Medium preset at each resolution. At 1080p, the range is 64 to 86 FPS, a 22 FPS spread. At 1440p, the range is 46 to 62 FPS, a 16 FPS spread. At 4K, the range is 28 to 38 FPS, a 10 FPS spread. This narrowing range at higher resolutions suggests that the GPU is consistently hitting its performance ceiling, with less headroom for variance.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this configuration depend heavily on the target resolution. At 1920x1080, the High preset at 62 FPS provides a good balance between visual fidelity and smoothness. For users who prioritize frame rate stability, the Medium preset at 75 FPS is the better choice, as it offers a 21% improvement over High while still maintaining acceptable visuals. The Low preset’s 92 FPS is the smoothest experience, but it sacrifices too much graphical detail for a horror game that relies on atmosphere.

At 2560x1440, the Low preset’s 66 FPS is the only viable option for a near-60 FPS experience. The Medium preset’s 54 FPS is borderline, but the minimum of 46 FPS could lead to noticeable hitches during intense scenes. The High and Ultra presets, at 44 FPS and 28 FPS respectively, are not recommended for regular play. Users should either stick to 1080p or accept the visual downgrade to Low at 1440p.

At 3840x2160, no preset provides a playable experience. The Low preset’s 41 FPS is the best case, but it falls short of the 60 FPS target and would likely feel sluggish. The data suggests avoiding 4K entirely with this GPU, as even the highest possible settings yield only 17 FPS. For users who must play at 4K, the Low preset is the only option, but it is not recommended for a smooth experience.

The Ultra preset is universally poor across all resolutions, with the best result being 39 FPS at 1080p. This preset appears to be designed for more powerful GPUs and should be avoided. The Medium preset offers the best balance of performance and quality, particularly at 1080p where it delivers 75 FPS with a minimum of 64 FPS, ensuring consistent frame times.

CPU Role

The AMD Ryzen 7 5700X3D is a formidable processor that is largely underutilized in this pairing. With 8 cores and 16 threads based on the Zen 3 architecture, it operates at a base clock of 3.00 GHz and a boost clock of 4.10 GHz. The CPU’s 96 MB of shared L3 cache is a standout feature, designed to reduce memory latency and improve gaming performance. Its benchmark scores are impressive, with a Cinebench R23 multi-core score of 22,366 and a single-core score of 3,157.

In the context of Downfall, the CPU’s role is to feed the GPU with draw calls and game logic. The measured FPS data shows that the CPU is not a bottleneck at any resolution. At 1080p Low, the 92 FPS result is likely near the GPU’s maximum output, as the RX 570’s 5.095 TFLOPS of FP32 compute can only produce so many frames. The CPU’s multi-threaded performance, as evidenced by its 26,318 Passmark multi-thread score, is more than sufficient for this task.

The CPU’s percentile ranking of 77 places it above the majority of processors, and its nearest rivals show its competitive standing. The AMD Ryzen 5 7600X3D has an average score of 24,728, which is 0.1% lower than the 5700X3D’s 24,709. The AMD Ryzen 9 5900HX scores 24,822, a 0.5% difference, while the Intel Core i5-12450HX and i5-11600 are 0.5% and 0.6% lower, respectively. These tiny deltas indicate that the 5700X3D is well-positioned in its segment.

The CPU’s 105 W TDP and socket AM4 compatibility make it a drop-in upgrade for many existing systems. Its support for DDR4 memory with a dual-channel bus and 51.2 GB/s bandwidth is adequate for gaming. In Downfall, the CPU’s 3D V-Cache (inferred from the X3D branding) likely helps with frame pacing, but the measured data cannot isolate this effect. The overall conclusion is that the Ryzen 7 5700X3D provides ample headroom for future GPU upgrades, as it is clearly not the limiting factor in this test.
