Downfall

# Downfall with AMD Ryzen 7 9850X3D + AMD Radeon RX 570

The AMD Ryzen 7 9850X3D paired with the AMD Radeon RX 570 produces a deeply lopsided result in Downfall: the CPU sits in the 92nd percentile among all processors with an average benchmark score of 58,386, while the GPU, with an average score of 28,766, lands in only the 74th percentile. This combination ranks 3547th out of 3716 tested combos in the game, placing it in the bottom 5% of all pairings. The bottleneck is unmistakable — the RX 570, a 14nm Polaris 20 part from 2017 with 4GB of GDDR5, is the limiting factor at every resolution, and the data confirms that no amount of CPU headroom can compensate for the GPU's fundamental throughput limits.

Resolution Scaling

The measured FPS data shows a predictable collapse as resolution climbs, but the pattern reveals exactly where the GPU runs out of headroom. At 1080p Low, the combo delivers 92 FPS average, which drops to 66 FPS at 1440p (a 28% reduction) and then to 41 FPS at 4K (a 55% reduction from 1080p). This scaling is far steeper than what a CPU-bound system would show — if the Ryzen 7 9850X3D were the limiting factor, the FPS drop from 1080p to 4K would be minimal because the CPU workload scales little with resolution. Instead, the 51 FPS gap between 1080p Low and 4K Low indicates the RX 570's pixel throughput is the ceiling.

Moving to Medium settings, the trend continues but with a tighter curve. At 1080p Medium, the average is 75 FPS with a minimum of 64 and maximum of 86. At 1440p Medium, that falls to 54 FPS (28% lower), and at 4K Medium, it reaches 33 FPS (56% lower than 1080p). The min/max spread at 1440p Medium (46-62 FPS) and 4K Medium (28-38 FPS) suggests frame pacing remains consistent even as the GPU saturates — there is no sudden stutter or CPU-related hitch, just a steady march downward.

High settings tell the same story with slightly lower absolute numbers: 62 FPS at 1080p, 44 FPS at 1440p (29% drop), and 27 FPS at 4K (56% drop). Ultra settings are the most punishing: 39 FPS at 1080p, 28 FPS at 1440p, and 17 FPS at 4K. The percentage drops from 1080p to 1440p across all settings cluster tightly between 28% and 29%, and the 1080p-to-4K drops cluster between 55% and 56%. This consistency is a hallmark of pure GPU-bound scaling — the CPU is not introducing any variable overhead that would distort the curve.

The 4K results are uniformly unplayable for smooth gameplay, with the best case being 41 FPS at Low settings. The 1440p results are playable only at Low (66 FPS) and Medium (54 FPS), while High dips to 44 FPS and Ultra to 28 FPS. At 1080p, the combo can manage 92 FPS at Low and 75 FPS at Medium, but High drops to 62 FPS and Ultra to 39 FPS. The data shows that the RX 570's 32 ROPs and 224.0 GB/s memory bandwidth are simply insufficient for Downfall's higher resolutions, regardless of how capable the Ryzen 7 9850X3D is.

GPU Role

The AMD Radeon RX 570 is a Polaris 20 chip built on GlobalFoundries' 14nm process, containing 5,700 million transistors on a 232 mm² die. It operates at a base clock of 1168 MHz and a boost clock of 1244 MHz, with memory running at 1750 MHz (7 Gbps effective). The 4GB GDDR5 frame buffer sits on a 256-bit bus, yielding 224.0 GB/s of bandwidth — a figure that becomes critically important in Downfall, a horror title that appears to tax memory throughput heavily based on the measured FPS scaling.

The GPU's 2048 shading units, 128 TMUs, and 32 ROPs produce a pixel rate of 39.81 GPixel/s and a texture rate of 159.2 GTexel/s. The FP32 throughput is 5.095 TFLOPS, which is the same as its FP16 figure (1:1). These specifications place the RX 570 in the 74th percentile among all GPUs, with an average benchmark score of 28,766. Its nearest rivals in the database are the AMD Radeon RX 6800M (average score 28,874, delta of -0.4%), the AMD Radeon R9 M295X (28,580, delta of +0.7%), the AMD Radeon RX 470 (28,996, delta of -0.8%), and the NVIDIA Quadro RTX 8000 (28,421, delta of +1.2%). The RX 570 is effectively within 1% of all these cards, meaning its performance class is tightly clustered — but that class is simply not enough for Downfall at higher resolutions.

The 4GB VRAM capacity is the most obvious constraint in this game. At 4K Ultra, the combo manages only 17 FPS, and even at 4K Low it reaches just 41 FPS. The 256-bit memory bus provides bandwidth that was competitive in 2017, but Downfall's texture and geometry demands at 1440p and above likely exceed the frame buffer capacity, forcing the GPU into memory thrashing. The fact that 1080p Low yields 92 FPS versus 4K Low's 41 FPS — a 2.24x difference for a 4x pixel count increase — suggests that the GPU is not purely pixel-bound; memory bandwidth and capacity are contributing to the shortfall.

The RX 570's boost clock of 1244 MHz is modest by modern standards, and the 150W TDP with a single 6-pin power connector reflects its older architecture. The GPU supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, so API compatibility is not the issue. The bottleneck is raw throughput. The data shows that the GPU's performance relative to its rivals is essentially flat — within 1.2% of the Quadro RTX 8000 and within 0.8% of the RX 470 — which means Downfall's results are consistent with the card's general standing, not an outlier due to driver or game-specific quirks.

CPU Role

The AMD Ryzen 7 9850X3D is a Zen 5 (Granite Ridge) processor on the AMD Socket AM5 platform, built on TSMC's 4nm process with 8,315 million transistors on a 70.6 mm² die. It has 8 cores and 16 threads, with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. The 96 MB of shared L3 cache is the headline feature, supported by 80 KB of L1 and 1 MB of L2 per core. The CPU supports DDR5 memory on a dual-channel bus with 89.6 GB/s bandwidth and ECC support. It includes 24 PCIe Gen 5 lanes and integrated Radeon Graphics, though those are irrelevant for this discrete GPU pairing.

The CPU's benchmark results place it in the 92nd percentile of all processors. Its Cinebench R23 scores are 22,807 multi-core and 2,228 single-core, while Cinebench R15 shows 3,551 multi-core and 343 single-core. Passmark results include a multi-thread score of 41,318, a single-thread score of 4,704, and a physics score of 4,171. The average benchmark score is 58,386, with nearest rivals including the Intel Xeon Platinum 8260M (58,323, delta of +0.1%), Intel Xeon w5-2545 (58,504, delta of -0.2%), Intel Core i9-14900 (58,115, delta of +0.5%), and AMD Ryzen AI 9 HX 470 (58,826, delta of -0.7%). The CPU is within 0.7% of all these rivals, confirming it is a top-tier part.

Despite this CPU horsepower, the measured FPS in Downfall shows no evidence of CPU limitation. At 1080p Low, the combo reaches 92 FPS, which is respectable but not exceptional — a CPU with this much single-thread performance (2,228 in R23 single-core) should be capable of far higher frame rates if the GPU could keep up. The fact that the 1080p Low result (92 FPS) is only 2.35x the 4K Low result (41 FPS) indicates the GPU is the constraint at both resolutions. If the CPU were the bottleneck at 1080p, we would see a much smaller FPS gap between 1080p and 1440p — but the data shows a consistent 28-29% drop, which is purely resolution-driven GPU scaling.

The 8-core/16-thread configuration with a 5.60 GHz boost clock is more than sufficient for Downfall, which is a 2016 horror title with modest CPU demands. The 120W TDP and the 4nm process node mean the CPU runs cool and efficient, but none of that matters when the GPU is delivering 17 FPS at 4K Ultra. The data suggests that swapping in a significantly weaker CPU would produce nearly identical FPS in this game, because the RX 570 saturates well before the Ryzen 7 9850X3D breaks a sweat. The CPU's 0.5% lead over the Core i9-14900 in average benchmark score is irrelevant here; the GPU's 74th percentile standing is the ceiling.

Settings Recommendations

The measured FPS data provides clear guidance for each resolution, and the verdict is straightforward: this combo belongs at 1080p with Low or Medium settings for smooth gameplay. At 1080p Low, the 92 FPS average is comfortably above the 60 FPS threshold for fluid motion. At 1080p Medium, the 75 FPS average with a 64 FPS minimum and 86 FPS maximum adds visual fidelity while staying playable. The 1080p High setting at 62 FPS is borderline — it is technically above 60 FPS, but the lack of min/max data for that row means there is no guarantee of consistency. Ultra at 1080p (39 FPS) is not recommended for anything other than screenshots.

At 1440p, the options narrow considerably. Low setting yields 66 FPS, which is playable but visually sparse. Medium setting drops to 54 FPS with a 46 FPS minimum, which is a significant compromise — the 46 FPS floor could cause noticeable stutter in a horror game where smooth camera movement is critical. High setting at 44 FPS and Ultra at 28 FPS are both below the smoothness threshold. The data suggests that 1440p Medium is the best balance for players who insist on higher resolution, but the 54 FPS average and 46 FPS minimum indicate that this is a compromise, not a recommendation.

At 4K, there is no good option. The best case is 41 FPS at Low, which is below 60 FPS and will feel sluggish. Medium at 33 FPS, High at 27 FPS, and Ultra at 17 FPS are all unplayable. The 4K results are included in the data for completeness, but no settings combination at this resolution produces acceptable performance. The 4GB VRAM and 224.0 GB/s bandwidth are fundamental limits that no settings tweak can overcome.

The overall recommendation is to run Downfall at 1080p Medium settings. This provides 75 FPS average with a 64 FPS minimum, which is a playable experience with moderate visual quality. Players who prioritize frame rate above all else can drop to Low for 92 FPS, but the visual downgrade is substantial. The 1080p High setting at 62 FPS is viable for players with adaptive sync displays, but the Medium setting offers a better safety margin. Avoid Ultra at any resolution, and treat 1440p as a stretch goal only at Low settings.

FAQ

Q: Can this combo run Downfall at 4K?

A: Technically yes, but not playably. The best 4K result is 41 FPS at Low settings, with Medium at 33 FPS, High at 27 FPS, and Ultra at 17 FPS. All 4K results are below 60 FPS, and the 4GB VRAM on the RX 570 is a hard constraint.

Q: Is the Ryzen 7 9850X3D holding back the RX 570?

A: No. The CPU is in the 92nd percentile with an average benchmark score of 58,386, while the GPU is in the 74th percentile with 28,766. The FPS scaling from 1080p to 4K shows a consistent 28-29% drop per resolution step at every settings level, which is pure GPU-bound behavior.

Q: What is the best settings preset for smooth gameplay?

A: 1080p Medium is the sweet spot, delivering 75 FPS average with a 64 FPS minimum and 86 FPS maximum. Low at 1080p reaches 92 FPS, but Medium offers significantly better visuals for only a 17 FPS cost.

Q: How does the RX 570 compare to its nearest GPU rivals in this game?

A: The RX 570's average benchmark score of 28,766 is within 1.2% of the NVIDIA Quadro RTX 8000 (28,421) and within 0.8% of the AMD Radeon RX 470 (28,996). The RX 6800M is 0.4% faster at 28,874, and the R9 M295X is 0.7% slower at 28,580. This combo's performance is consistent with that class.

Q: Why does the FPS drop so much from 1080p to 4K?

A: The RX 570 has 4GB of GDDR5 on a 256-bit bus with 224.0 GB/s bandwidth, plus 32 ROPs. The 4K pixel count requires 4x the fill rate of 1080p, and the card's 39.81 GPixel/s pixel rate is insufficient. The 55-56% FPS drop from 1080p to 4K across all settings confirms the GPU is the limiting component.

Q: Is the CPU's 96MB L3 cache helping in Downfall?

A: The data does not indicate any measurable benefit from the large cache in this game. The FPS results are consistent with GPU-bound scaling, and the CPU's 2,228 Cinebench R23 single-core score is far more than Downfall requires. The cache is a general-purpose advantage, not a specific one for this title.

High settings drop to 62 FPS average. Ultra settings fall to 39 FPS average. The spread from Low to Ultra is 53 FPS, representing a 57.6% performance penalty for maximum visual quality.

At 2560x1440, the performance tier shifts downward. Low settings average 66 FPS. Medium settings average 54 FPS with a 46 FPS minimum and 62 FPS maximum. High settings average 44 FPS. Ultra settings average 28 FPS. The Low-to-Ultra spread is 38 FPS, a 57.6% penalty that mirrors the 1080p pattern, confirming the scaling is resolution-independent.

At 3840x2160, the results are marginal. Low settings average 41 FPS. Medium settings average 33 FPS with a 28 FPS minimum and 38 FPS maximum. High settings average 27 FPS. Ultra settings average 17 FPS. The Low-to-Ultra spread is 24 FPS, a 58.5% penalty. The 4K Medium min/max range of 28-38 FPS shows consistent frame delivery, but at a level that is not playable for most users.

The complete measured data set is as follows: 1080p Low 92 FPS, 1080p Medium 75 FPS (min 64, max 86), 1080p High 62 FPS, 1080p Ultra 39 FPS; 1440p Low 66 FPS, 1440p Medium 54 FPS (min 46, max 62), 1440p High 44 FPS, 1440p Ultra 28 FPS; 4K Low 41 FPS, 4K Medium 33 FPS (min 28, max 38), 4K High 27 FPS, 4K Ultra 17 FPS. The only rows with min/max data are Medium settings across all three resolutions, which show consistent 20-22 FPS ranges, indicating stable frame pacing without severe hitches. The absence of min/max data for Low, High, and Ultra rows means those results should be treated as averages only, with unknown variance.
