Downfall

Downfall’s measured frame rates across the 1080p, 1440p, and 4K resolutions reveal a system that is heavily constrained by its graphics solution. The AMD Ryzen 7 5800XT and Intel Arc B370 combination produces playable results only at the lowest settings and resolutions, with the data indicating a clear and consistent pattern of performance degradation as pixel count increases. This analysis strictly uses the provided measured FPS rows, CPU and GPU benchmark scores, and ranking data to interpret how this specific hardware pairing behaves in this 2016 horror title.

Resolution Scaling

The measured FPS data for Downfall shows a predictable but steep decline as resolution increases from 1920x1080 to 3840x2160. At 1080p with Low settings, the combo averages 96 FPS, which is the highest frame rate recorded for this configuration. Moving to 2560x1440 at Low settings drops the average to 68 FPS, a reduction of 28 FPS or roughly 29% from the 1080p result. At 4K (3840x2160) with Low settings, the average falls further to 43 FPS, which is less than half of the 1080p Low figure. This scaling pattern indicates that the GPU is the primary limiting factor, as the frame rate drops almost proportionally with the increase in pixel count.

The High settings preset tells a similar story, though the absolute numbers are lower. At 1920x1080 High, the system produces 64 FPS average. At 2560x1440 High, the average drops to 46 FPS, a 28% decrease. At 3840x2160 High, the average plummets to 29 FPS, which is below the threshold for smooth gameplay in most scenarios. The delta between 1080p and 4K at High settings is 35 FPS, showing that the rendering load at 4K overwhelms the Intel Arc B370’s capabilities.

Medium settings provide the only resolution where min and max FPS values are recorded for all three resolutions. At 1920x1080 Medium, the average is 78 FPS, with a minimum of 67 FPS and a maximum of 90 FPS. At 2560x1440 Medium, the average drops to 56 FPS, with min/max of 48 and 64 FPS respectively. At 3840x2160 Medium, the average is 35 FPS, with min/max of 30 and 40 FPS. The minimum FPS figures are particularly telling: even at 1080p Medium, the minimum of 67 FPS suggests occasional dips, while at 4K Medium the minimum of 30 FPS means the game will stutter noticeably during intense scenes.

Ultra settings are the most demanding, and the results are consistently poor. At 1920x1080 Ultra, the average is 40 FPS, which is only marginally playable. At 2560x1440 Ultra, the average drops to 29 FPS. At 3840x2160 Ultra, the average falls to 18 FPS, which is essentially unplayable for a horror game that relies on atmospheric tension and smooth camera movement. The scaling from 1080p to 4K at Ultra settings shows a 22 FPS drop, representing a 55% reduction in performance. This steep decline underscores that the Arc B370 simply does not have the throughput to handle Downfall’s Ultra preset at higher resolutions.

The data suggests that the CPU is not the bottleneck at any resolution. The Ryzen 7 5800XT has a substantial multi-threaded score of 23,794 in Cinebench R23 and a Passmark multithread score of 28,053, indicating strong processing power. Meanwhile, the Arc B370’s only benchmark score is 1,184 in 3DMark Steel Nomad DX12, placing it in the 5th percentile of all GPUs. The frame rate drops align much more closely with GPU workload scaling than with any CPU limitation. If the CPU were the constraint, the frame rates would remain relatively flat across resolutions; instead, they drop consistently, confirming that the Intel Arc B370 is the limiting component.

GPU Role

The Intel Arc B370 is an integrated graphics solution based on the Xe3-LPG architecture, built on a 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2400 MHz. The memory configuration is listed as “System Shared,” meaning the GPU draws from the system’s main memory rather than dedicated VRAM. The memory bus width and bandwidth are similarly system-dependent, which in practice means that performance can vary based on the host system’s RAM configuration. The Ryzen 7 5800XT supports DDR4 memory with dual-channel architecture and a memory bandwidth of 51.2 GB/s, so the Arc B370 is limited to that shared pool.

The GPU’s performance metrics are modest. It has 1,280 shading units, 40 texture mapping units, and 20 render output units. The pixel rate is 48.00 GPixel/s, and the texture rate is 96.00 GTexel/s. The FP32 performance is 6.144 TFLOPS. These specifications place the Arc B370 far below dedicated gaming GPUs. Its 3DMark Steel Nomad DX12 score of 1,184 is the only benchmark recorded, and it places the GPU in the 5th percentile of all GPUs. The nearest rivals in the data are the ATI Mobility Radeon HD 5570 with a score of 1,186, and the ATI Radeon HD 5770 with a score of 1,190. The Arc B370’s score is 0.2% lower than the HD 5570 and 0.5% lower than the HD 5770. This comparison highlights that despite being a modern part, its raw performance is comparable to GPUs from over a decade ago.

In Downfall specifically, the GPU’s limitations manifest clearly. The highest average FPS recorded is 96 at 1080p Low, which is playable. However, any increase in resolution or settings quickly pushes the system into sub-60 FPS territory. At 1440p High, the average is 46 FPS, and at 4K High, it drops to 29 FPS. The VRAM situation is critical: with “System Shared” memory, the GPU competes with the CPU for memory bandwidth. Downfall, being a 2016 game, likely does not require massive amounts of VRAM, but the shared memory architecture still introduces latency and bandwidth contention that a dedicated GPU would avoid. The boost clock of 2400 MHz is reasonable for an integrated part, but the low base clock of 300 MHz suggests that the GPU may spend significant time at lower frequencies under sustained load, further reducing performance.

The data shows that the Arc B370 is the definitive bottleneck. The Ryzen 7 5800XT’s CPU benchmarks are strong — a Cinebench R23 multicore score of 23,794 and a Passmark single-thread score of 3,535 — but these cannot compensate for the GPU’s lack of throughput. In a horror game like Downfall, which relies on lighting and shadow effects, the GPU’s 20 ROPs and 6.144 TFLOPS are insufficient for higher presets. The 4K Ultra result of 18 FPS is particularly indicative: this is a GPU-bound scenario where the CPU has ample headroom, yet the frame rate collapses due to the GPU’s fill rate and shading limitations.

How This Combo Ranks

In the benchmark database, the combination of the AMD Ryzen 7 5800XT and Intel Arc B370 in Downfall ranks 2,688 out of 2,928 tested combos. This places the pairing in the bottom 8% of all configurations tested for this game. The rank reflects the severe GPU bottleneck discussed earlier. The CPU itself is not the issue; the Ryzen 7 5800XT has a percentile rank of 81 among all CPUs, meaning it outperforms 81% of tested processors. Its average benchmark score is 29,879, which is nearly identical to its nearest rivals: the AMD Ryzen 7 7840H scores 29,868 (0% delta), the AMD Ryzen 7 8845HS scores 29,955 (-0.3% delta), and the AMD Ryzen 5 9600X scores 29,713 (0.6% delta). This indicates that the CPU is a capable mid-to-high-range part.

However, the GPU’s percentile rank of 5 places it in the bottom 5% of all GPUs. The Arc B370’s average benchmark score of 1,184 is only 0.2% lower than the ATI Mobility Radeon HD 5570 and 0.5% lower than the ATI Radeon HD 5770. This extreme disparity between CPU and GPU performance is the root cause of the low combo rank. The combo rank of 2,688 out of 2,928 suggests that most other tested configurations, even those with weaker CPUs, achieve better frame rates in Downfall because they are paired with more capable graphics solutions.

The data implies that if the Ryzen 7 5800XT were paired with even a modest dedicated GPU, the combo rank would improve substantially. The CPU’s 8 cores and 16 threads, along with its 32 MB of shared L3 cache, provide more than enough processing power for Downfall, which is a CPU-light horror title. The measured FPS data supports this: at 1080p Low, the system achieves 96 FPS, which is a reasonable result for a low-end GPU. But at 4K Ultra, the system falls to 18 FPS, a result that is 40% slower than the 1080p Low result. The combo rank is thus a reflection of the GPU’s inability to handle higher resolutions, not the CPU’s.

CPU Role

The AMD Ryzen 7 5800XT is a desktop processor from the 5000 series, based on the Zen 3 architecture (codename Vermeer). It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. The CPU is built on a 7 nm process by TSMC, with 4,150 million transistors on a 74 mm² die. It has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 32 MB of shared L3 cache. The memory support is DDR4 with dual-channel architecture, providing a memory bandwidth of 51.2 GB/s. The CPU supports ECC memory and has 20 PCIe Gen 4 lanes. It was released on July 30, 2024, with a launch MSRP of $249.

In Downfall, the CPU’s role is secondary to the GPU, but its capabilities ensure that it never becomes the limiting factor. The Cinebench R23 multicore score of 23,794 and single-core score of 3,359 indicate strong performance for both multi-threaded and single-threaded workloads. The Passmark multithread score of 28,053 and single-thread score of 3,535 further confirm this. The 3DMark scores show scaling from 1,879 for 2 threads to 7,683 for 16 threads, with an 8-thread score of 6,141 and a max-thread score of 7,680. These scores suggest that the CPU can handle Downfall’s game logic, AI, and physics without breaking a sweat.

The CPU’s 4.80 GHz boost clock is particularly beneficial for a game like Downfall, which likely relies on single-thread performance for rendering calls and game state updates. The single-thread benchmark scores (3,359 in Cinebench R23, 3,535 in Passmark) place it well above the threshold needed for smooth gameplay. The 32 MB of L3 cache also helps keep frequently accessed data close to the cores, reducing memory latency. However, the measured FPS data shows that even with this strong CPU, the frame rates are limited by the GPU. At 1080p Low, the system hits 96 FPS, which is likely near the CPU’s maximum for this game, but at 4K Ultra, the GPU drops the frame rate to 18 FPS, proving that the CPU has ample headroom.

The CPU’s nearest rivals in the database are the AMD Ryzen 7 7840H, AMD Ryzen 7 8845HS, AMD Ryzen 7 7840HS, and AMD Ryzen 5 9600X. The delta percentages are minimal (0% to 0.6%), indicating that the Ryzen 7 5800XT performs essentially identically to these parts in general benchmarks. In Downfall specifically, the CPU’s performance is more than sufficient, and the combo rank of 2,688 is almost entirely attributable to the GPU. If the user were to upgrade the GPU while keeping the Ryzen 7 5800XT, the frame rates would improve dramatically, especially at higher resolutions.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for the AMD Ryzen 7 5800XT and Intel Arc B370 in Downfall depend heavily on the target resolution. At 1920x1080, the Medium preset offers the best balance of visual quality and performance. The average FPS is 78, with a minimum of 67 and a maximum of 90. This ensures that the game remains playable even during demanding scenes. The Low preset at 1080p achieves 96 FPS average, which is smoother, but the visual downgrade may detract from the horror atmosphere. The High preset at 1080p averages 64 FPS, which is playable but with less headroom for dips. The Ultra preset at 1080p averages 40 FPS, which is borderline and likely to feel choppy in a horror game that uses sudden movements.

At 2560x1440, the Low preset is the only viable option for consistent performance. It averages 68 FPS, which is smooth. The Medium preset averages 56 FPS, with a minimum of 48 FPS, which may result in occasional stutters. The High preset drops to 46 FPS, and the Ultra preset falls to 29 FPS, both of which are below the threshold for comfortable gameplay. For 1440p users, the data clearly recommends Low settings to maintain a playable experience. The Medium preset is a compromise if the user can tolerate frame rate dips below 50 FPS.

At 3840x2160, none of the settings provide a truly smooth experience. The Low preset averages 43 FPS, which is the best result at this resolution but still below 60 FPS. The Medium preset averages 35 FPS, with a minimum of 30 FPS, which will be noticeably stuttery. The High preset averages 29 FPS, and the Ultra preset averages 18 FPS, both of which are unplayable for a game that requires responsive controls. For 4K, the recommendation is to use Low settings and accept the 43 FPS average, or to lower the resolution entirely.

The data suggests that the best overall experience is at 1920x1080 with Medium settings. This configuration provides an average of 78 FPS, a minimum of 67 FPS, and a maximum of 90 FPS, which offers both visual quality and smoothness. The Medium preset likely includes moderate shadows and textures, which are important for a horror game’s atmosphere, without the performance penalty of High or Ultra. The 1440p Medium preset (56 FPS average) is a secondary option for users with higher-resolution monitors, but the 1080p Medium result is the most balanced. The Ultra preset is not recommended at any resolution, as the 40 FPS at 1080p is the highest it achieves, and it drops to 18 FPS at 4K. The measured data clearly indicates that the Intel Arc B370 is a low-end GPU, and the settings recommendations must reflect that reality.
