Downfall

# Downfall with AMD Ryzen 5 5600X + Intel Arc B370

This combination delivers playable frame rates at 1080p and 1440p with adjusted settings, but the Intel Arc B370's position as a low-percentile GPU (5th percentile vs. all GPUs) makes 4K Ultra a slideshow at 18 FPS. The AMD Ryzen 5 5600X, sitting at the 75th percentile among all CPUs, is not the limiting factor in this pairing; the GPU's performance ceiling dominates the measured results across every resolution and settings tier. The data shows a classic GPU-bound scenario where the CPU's strong multi-threaded and single-threaded scores cannot compensate for the Arc B370's modest graphics throughput in this horror title.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and consistent, revealing the GPU as the definitive bottleneck. At High settings, the average FPS falls from 64 at 1920x1080 to 46 at 2560x1440—a 28% reduction—then further to 29 at 3840x2160, which represents a 55% loss from the 1080p baseline. This pattern holds across all settings tiers: Low settings go from 96 FPS at 1080p to 68 at 1440p (a 29% drop) and 43 at 4K (a 55% drop from 1080p). The scaling is nearly linear with pixel count, indicating that the render pipeline is saturated by the GPU's fill rate and shading capacity rather than any CPU-side constraint.

The Medium settings tier provides the only complete min/max data, and it reinforces the GPU-bound conclusion. At 1080p Medium, the average is 78 FPS with a minimum of 67 and maximum of 90. Moving to 1440p Medium drops the average to 56 FPS (min 48, max 64), and 4K Medium falls to 35 FPS (min 30, max 40). The minimum frame rates scale proportionally with the averages, suggesting no sudden CPU-related stutters or frame-time spikes that would indicate processor limitation. The Intel Arc B370's pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are the hardware ceilings that these numbers reflect.

At Ultra settings, the resolution scaling becomes brutal. The 1080p Ultra average is 40 FPS, which drops to 29 at 1440p (a 27.5% reduction) and 18 at 4K (a 55% reduction). The 4K Ultra result of 18 FPS is below the threshold for smooth gameplay in a horror title, where responsiveness matters for atmosphere and reaction. The data suggests that even 1440p Ultra is marginal, while 1080p High and Medium are the practical sweet spots for this combo. The scaling pattern across all four settings tiers—High, Medium, Low, and Ultra—shows remarkable consistency in the percentage drops, which is a hallmark of a purely GPU-limited system where the CPU's 6 cores and 12 threads are never the constraint.

FAQ

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

A: The measured data shows 1920x1080 as the only resolution where all settings tiers achieve playable averages. At 1080p, Low averages 96 FPS, Medium averages 78 FPS, High averages 64 FPS, and even Ultra averages 40 FPS. At 1440p, only Low (68 FPS) and Medium (56 FPS) exceed 30 FPS averages, while 4K never reaches 45 FPS even at Low settings.

Q: How does the Intel Arc B370 compare to its nearest GPU rivals?

A: The Arc B370's 3DMark Steel Nomad DX12 score of 1184 places it at the 5th percentile among all GPUs. Its nearest rival, the ATI Mobility Radeon HD 5570, scores 1186 (0.2% higher), while the ATI Radeon HD 5770 scores 1190 (0.5% higher). The AMD Radeon HD 7650M scores 1192 (0.7% higher), and the AMD FirePro M2000 scores 1168 (1.4% lower). These are all legacy or low-end parts, confirming the Arc B370's entry-level positioning.

Q: Is the AMD Ryzen 5 5600X strong enough for this game?

A: Yes, the CPU data indicates ample headroom. The Ryzen 5 5600X scores 11,838 in Cinebench R23 multi-core and 1,541 in single-core, with a PassMark multi-thread score of 21,858 and single-thread score of 3,364. The 75th percentile ranking among all CPUs, combined with the GPU-bound scaling pattern observed in the FPS data, means the processor is not the limiting factor in this pairing.

Q: What settings should a user prioritize for 1440p gameplay?

A: The measured data indicates Medium settings are the highest playable tier at 2560x1440, with an average of 56 FPS (min 48, max 64). High settings at 1440p average 46 FPS, which is playable but closer to the edge. Low settings at 1440p reach 68 FPS average, providing smoother motion for users who prefer higher frame rates over visual fidelity. Ultra at 1440p averages only 29 FPS, which is not recommended.

Q: How does the combo rank among all tested combinations?

A: The combo ranks 2,688th out of 2,928 tested combinations in Downfall, placing it in the bottom 8.2% of all configurations. This low ranking is consistent with the GPU's 5th percentile standing, while the CPU's 75th percentile performance cannot boost the overall result in a GPU-bound title.

Q: What does the 4K performance indicate about the GPU's memory subsystem?

A: The Arc B370 uses System Shared memory with System Dependent bandwidth, meaning it relies on the host system's DDR4 memory through the IGP bus interface. At 3840x2160, even Low settings only average 43 FPS, and Ultra drops to 18 FPS. The shared memory architecture and the GPU's 6.144 TFLOPS FP32 compute are insufficient for the pixel throughput demanded at 4K in this horror title.

How This Combo Ranks

The combination of the AMD Ryzen 5 5600X and Intel Arc B370 ranks 2,688th out of 2,928 tested combos in Downfall, placing it in the bottom 8.2% of all configurations. This ranking is heavily weighted by the GPU's performance class. The Arc B370 sits at the 5th percentile among all GPUs, with an average benchmark score of 1184 in 3DMark Steel Nomad DX12. Its nearest rivals are all legacy parts from over a decade ago, including the ATI Mobility Radeon HD 5570 (1186, 0.2% faster) and ATI Radeon HD 5770 (1190, 0.5% faster). The only GPU in its immediate vicinity that it beats is the AMD FirePro M2000 (1168, 1.4% slower).

The CPU does not rescue this ranking. The Ryzen 5 5600X is a 75th-percentile processor with an average benchmark score of 21,771, placing it just 0.1% above the AMD Ryzen 7 4800H (21,749) and 0.5% above the AMD Ryzen 5 PRO 6650U (21,874) and Intel Core i7-11700 (21,891). Its Cinebench R23 scores of 11,838 multi-core and 1,541 single-core are respectable for a 6-core, 12-thread Zen 3 part, but in a GPU-bound title like Downfall, the processor's strong showing in synthetic benchmarks does not translate into higher frame rates. The combo rank of 2,688 out of 2,928 reflects the reality that the Arc B370's 6.144 TFLOPS FP32 throughput and 48.00 GPixel/s pixel rate are the constraining factors across all measured resolutions.

The gap between the CPU's and GPU's percentile standings—75th versus 5th—creates a significant imbalance. For users upgrading from an older GPU, the data suggests that the Ryzen 5 5600X has substantial headroom to drive a more powerful graphics card in this title. The measured FPS results show no CPU-related bottlenecks, as the frame rate scales predictably with resolution and settings changes.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings average 96 FPS, providing a smooth experience well above refresh rate thresholds. Medium settings average 78 FPS with a minimum of 67 and maximum of 90, offering a good balance of visual quality and performance. High settings average 64 FPS, which is solid for a horror game where slower pacing is common. Ultra settings average 40 FPS, which is playable but shows the GPU struggling with the highest fidelity options.

Moving to 2560x1440, the performance drops are noticeable but manageable at lower settings. Low settings average 68 FPS, still comfortably playable. Medium settings average 56 FPS with a minimum of 48 and maximum of 64, keeping frame times consistent. High settings average 46 FPS, which dips below the 60 FPS ideal but remains acceptable for the genre. Ultra settings average 29 FPS, crossing below the 30 FPS playability threshold and indicating the GPU is overwhelmed.

At 3840x2160, only Low settings approach playability. Low averages 43 FPS, which is borderline but usable in a slower-paced horror title. Medium averages 35 FPS with a minimum of 30 and maximum of 40, sitting right at the edge of acceptable performance. High averages 29 FPS, falling below the playability line. Ultra averages 18 FPS, which is effectively unplayable and demonstrates the Arc B370's limits at 4K resolution.

The Medium settings tier provides the only min/max data across all resolutions, allowing for frame time analysis. At 1080p, the spread from 67 to 90 FPS around the 78 average shows reasonable consistency. At 1440p, the 48 to 64 FPS range around the 56 average maintains similar relative variance. At 4K, the 30 to 40 FPS range around the 35 average tightens, suggesting that at higher resolutions, the GPU is consistently saturated rather than experiencing intermittent spikes or drops. The absence of min/max data for other settings tiers limits deeper analysis, but the available numbers indicate stable frame delivery without CPU-induced stuttering.

GPU Role

The Intel Arc B370 is the defining component in this pairing, and its specifications explain the measured results. Built on Intel's 3 nm process with the Xe3-LPG architecture, this GPU features 1,280 shading units, 40 texture mapping units, and 20 raster output pipelines. Its boost clock of 2400 MHz (base 300 MHz) drives a pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s, with FP32 compute of 6.144 TFLOPS. The GPU's 5th percentile standing among all GPUs, with a 3DMark Steel Nomad DX12 score of 1184, places it in direct competition with GPUs from the early 2010s.

The memory configuration is particularly relevant for Downfall's performance. The Arc B370 uses System Shared memory with System Dependent bandwidth, meaning it draws from the host's DDR4 memory pool through the IGP bus interface. This architecture is typical of integrated-class graphics, and the data reflects its limitations. At 4K Ultra, the 18 FPS average suggests the shared memory bandwidth cannot sustain the texture and geometry loads required at that resolution. The GPU's 20 ROPs are a severe constraint at high pixel counts, explaining why resolution scaling is so punishing.

The GPU's 10 ray tracing cores and DirectX 12 Ultimate (12_2) API support are present, but Downfall is a 2016 horror title that predates widespread ray tracing adoption. The game's rendering workload likely relies on traditional rasterization, which is precisely where the Arc B370's modest ROP count and fill rate become limiting factors. The 25 W TDP and IGP form factor indicate this is not designed for high-end gaming, and the measured FPS data across all 12 configurations confirms that expectation. The GPU's nearest rivals—all ATI/AMD parts from the HD 5000/7000 era—underscore its position as an entry-level solution.

CPU Role

The AMD Ryzen 5 5600X provides a solid foundation that the Arc B370 cannot fully utilize in Downfall. This 6-core, 12-thread processor based on Zen 3 architecture (codenamed Vermeer) operates at a 3.70 GHz base clock with a 4.60 GHz boost clock on a 7 nm TSMC process. Its cache hierarchy includes 64 KB L1 per core, 512 KB L2 per core, and 32 MB L3, with dual-channel DDR4 memory support providing 51.2 GB/s bandwidth. The CPU's 75th percentile ranking among all CPUs, with an average benchmark score of 21,771, places it just above the AMD Ryzen 7 4800H (0.1% higher) and Intel Core i7-11700 (0.5% higher).

Synthetic benchmarks show the Ryzen 5 5600X's capabilities. Cinebench R23 scores of 11,838 multi-core and 1,541 single-core demonstrate strong multi-threaded performance for its 65 W TDP. Geekbench scores of 9,173 multi-core and 1,989 single-core corroborate this. PassMark results are particularly thorough: multi-thread score of 21,858, single-thread of 3,364, integer math of 71,161, floating point math of 39,487, and extended instructions of 16,991. The processor's 3DMark scores—5,582 for 16 threads, 5,588 for max threads, and 917 for single-thread—show scaling efficiency across thread counts.

In Downfall, however, the CPU's role is secondary. The measured FPS scaling from 1080p to 4K follows pixel count almost exactly, which is the signature of a GPU-bound workload. If the CPU were limiting, the frame rates would show less degradation at higher resolutions, as the processor would still be feeding frames at its maximum rate. Instead, the 55% drop from 1080p to 4K at both Low and High settings indicates the GPU's pixel throughput is the constraint. The Ryzen 5 5600X's 4,150 million transistors and 74 mm² die size give it ample compute headroom for this 2016 title, and its 12 threads are more than sufficient for the game's threading model. The processor's strong single-thread performance (Cinebench R23 single-core of 1,541, PassMark single-thread of 3,364) ensures that even lightly threaded game logic is handled without delay, but this advantage is invisible in the final frame rates because the GPU cannot keep up.
