Downfall

# Downfall with AMD Ryzen 9 5950X + Intel Arc B570

The AMD Ryzen 9 5950X paired with the Intel Arc B570 produces a playable but uneven experience in Downfall, a 2016 horror title that scales predictably across the four tested presets. At 1080p, the combination delivers strong frame rates ranging from 68 FPS at Ultra to 163 FPS at Low, but the gap between presets widens dramatically at 4K, where Ultra drops to 30 FPS while Low maintains 72 FPS. The dataset shows a system that is clearly GPU-limited at higher resolutions and settings, with the 16-core, 32-thread CPU never appearing as the bottleneck in any measured configuration.

Settings Recommendations

For the best balance of visual quality and frame pacing, the Medium preset is the clear sweet spot across all three resolutions. At 1080p, Medium produces 133 FPS average with a minimum of 113 FPS and maximum of 153 FPS, which is only 18% below the Low preset's 163 FPS but delivers substantially better visuals than Low. The 1440p Medium result of 95 FPS (81 minimum, 110 maximum) remains comfortably above 60 FPS, making it suitable for high-refresh monitors. Even at 4K, Medium holds 59 FPS with a 50 FPS minimum, keeping the experience fluid on standard 60 Hz displays.

High settings are viable at 1080p and 1440p, yielding 109 FPS and 78 FPS respectively, but the 4K High result of 49 FPS falls short of the 60 FPS target. Ultra settings should be avoided at 4K entirely, as the 30 FPS average makes the game feel sluggish; at 1440p Ultra the 49 FPS average is borderline, and only at 1080p does Ultra reach a respectable 68 FPS. Low settings provide the highest frame rates but sacrifice visual fidelity, and the data suggests they are only necessary for 4K users targeting maximum smoothness, the 72 FPS at 4K Low is the only way to reach 60+ FPS at that resolution.

The measured minimum frame times from Medium settings indicate consistent performance: the 4K Medium minimum of 50 FPS is only 15% below the average, and the 1440p and 1080p minimums are 85% and 85% of their averages respectively. This suggests the game is not experiencing severe stutter or frame time spikes at Medium, making it the most predictable preset for competitive or tense horror gameplay where sudden frame drops can be jarring.

GPU Role

The Intel Arc B570's specifications directly explain the performance ceiling observed in Downfall. With 10 GB of GDDR6 memory on a 160-bit bus delivering 380.0 GB/s of bandwidth, the card has sufficient memory capacity for this 2016 title, but the bandwidth and compute resources determine the scaling pattern. The GPU's 2304 shading units, 144 texture mapping units, and 80 render output units combine for 11.52 TFLOPS FP32 performance, which places it in the 65th percentile of all GPUs in the database.

The memory clock runs at 2375 MHz (19 Gbps effective), and the base and boost clocks are both locked at 2500 MHz, a flat clock curve that suggests consistent sustained performance rather than bursty boosts. The 5 nm process node from TSMC with 19,600 million transistors on a 272 mm² die indicates a modern architecture (Xe2-HPG, Battlemage generation) that handles DirectX 12_2, Vulkan 1.4, and OpenGL 4.6. Downfall, being a 2016 release, likely uses older DirectX paths, and the Arc B570's driver overhead on legacy APIs could explain why the card's performance relative to its theoretical compute is modest.

Comparing to nearest rivals, the Arc B570's average benchmark score of 20556 is essentially tied with the NVIDIA GeForce RTX 3070 Mobile (20534, 0.1% delta) and the Intel Arc A750 (20582, -0.1% delta). This means the B570 performs within 0.5% of its closest competitors in synthetic tests, yet the in-game results show a wide spread between presets. The GPU's 65th percentile ranking indicates it is a mid-range performer, and the measured frame rates in Downfall align with that positioning, capable at 1080p and 1440p, but struggling to maintain high presets at 4K.

Resolution Scaling

The frame rate drops from 1080p to 4K reveal a classic GPU-bound scenario. At Low settings, 1080p produces 163 FPS, 1440p drops to 116 FPS (a 29% reduction), and 4K falls to 72 FPS (a 56% reduction from 1080p). This scaling is steeper than the pixel count increase alone would suggest, 4K has 4 times the pixels of 1080p, indicating that the Arc B570's memory bandwidth and fill rate become limiting factors at higher resolutions.

Medium settings show a similar pattern: 133 FPS at 1080p, 95 FPS at 1440p (71% of 1080p), and 59 FPS at 4K (44% of 1080p). The gap between Low and Medium narrows as resolution increases, from 18% at 1080p to 22% at 1440p and 18% at 4K, suggesting that the GPU's compute resources handle the extra pixel work proportionally across presets. High settings demonstrate the steepest scaling drop: 109 FPS at 1080p falls to 78 FPS at 1440p (72%) and 49 FPS at 4K (45%). Ultra settings compress the range further, with 68 FPS at 1080p dropping to 49 FPS at 1440p (72%) and 30 FPS at 4K (44%).

The consistent 44-45% retention from 1080p to 4K across Medium, High, and Ultra presets strongly indicates the GPU is the sole limiting component. A CPU-bound system would show diminishing frame rate differences as resolution increases, but here the proportional scaling matches pixel throughput expectations for a GPU with 200.0 GPixel/s pixel rate and 360.0 GTexel/s texture rate.

Measured FPS Breakdown

At 1920x1080, the full preset range is playable. Low settings deliver 163 FPS average, Medium produces 133 FPS with a minimum of 113 FPS and maximum of 153 FPS, High reaches 109 FPS, and Ultra manages 68 FPS. The 95 FPS difference between Low and Ultra represents a 140% performance spread, giving players substantial headroom to prioritize visual fidelity or frame rate.

At 2560x1440, the same ordering persists but the gaps compress. Low settings achieve 116 FPS, Medium drops to 95 FPS (81 minimum, 110 maximum), High falls to 78 FPS, and Ultra lands at 49 FPS. The Ultra preset at 1440p is the first configuration to drop below 60 FPS, though the 49 FPS average remains playable for a horror title where slower pacing is acceptable. Medium and High both remain above 60 FPS, making them the recommended options for 1440p displays.

At 3840x2160, only Low and Medium maintain playable frame rates. Low produces 72 FPS, Medium averages 59 FPS with a 50 FPS minimum and 68 FPS maximum, High drops to 49 FPS, and Ultra falls to 30 FPS. The 42 FPS difference between Low and Ultra at 4K is smaller in absolute terms than at 1080p, but the relative impact is severe, Ultra at 4K runs at 43% of Low's frame rate. The Medium preset's minimum of 50 FPS is just above the threshold where frame pacing becomes noticeable, making it the highest preset that can be recommended for 4K without compromises.

The measured data shows no anomalies or outliers; the progression from Low to Ultra is monotonic at every resolution, and the minimum frame times from Medium settings are consistently 85% of their respective averages. This indicates stable performance without thermal throttling or driver-related stutters in the tested configurations.

CPU Role

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture (Vermeer codename) built on TSMC's 7 nm process. It operates at a 3.40 GHz base clock and boosts to 4.90 GHz, with a 64 MB L3 cache and 512 KB L2 per core. The CPU's 105 W TDP and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide adequate performance for gaming workloads, though Downfall's age means it likely uses fewer threads than modern titles.

In synthetic benchmarks, the 5950X scores 26017 in Cinebench R23 multi-core and 1614 in single-core, with a Geekbench multi-core score of 15233 and single-core of 2083. Its 3DMark scores scale from 944 in single-thread to 11597 in max-thread tests, showing strong multi-threaded scaling. The Passmark multi-thread score of 45424 and single-thread of 3470 place it in the 91st percentile of all CPUs, with an average benchmark score of 51947.

Compared to its nearest rivals, the 5950X is tightly clustered: the Intel Core Ultra 5 235HX scores 52073 (-0.2% delta), the AMD EPYC 8124P scores 52121 (-0.3% delta), and the Intel Core i7-14700 scores 52301 (-0.7% delta). Only the Intel Core i9-13900F scores lower at 51730 (0.4% delta). This grouping means the 5950X's CPU performance is statistically indistinguishable from these competitors in aggregate benchmarks.

In Downfall specifically, the CPU's role appears minimal given the GPU-bound scaling pattern. The 4K to 1080p frame rate ratios (44-45% across Medium, High, Ultra) are consistent with pure GPU limitations, and the 1080p Low preset's 163 FPS suggests the CPU can feed frames well above what the Arc B570 can render at higher settings. The 5950X's architecture from 2020, with its high single-thread performance (Cinebench R23 single-core 1614), is more than sufficient for a 2016 horror title that does not demand modern multi-threaded optimizations.
