Downfall

The AMD Ryzen 7 5800X paired with the Intel Arc B370 produces a highly constrained gaming experience in Downfall, with benchmark results indicating that the graphics processor is the definitive performance limiter across all tested resolutions and settings. The combo ranks in the 2688th position out of 2928 tested combinations, placing it in the bottom 8% of all systems evaluated for this title, which aligns with the Arc B370's position in the 5th percentile of all GPUs.

Resolution Scaling

The measured FPS data reveals a predictable but steep performance curve as resolution increases, with the frame rate dropping by 33% when moving from 1920x1080 to 2560x1440 at High settings, and a further 37% drop when moving from 2560x1440 to 3840x2160. This translates to average framerates of 64, 46, and 29 FPS respectively, showing that the scaling penalty becomes more severe at higher resolutions.

At Low settings, the resolution scaling pattern is similar but slightly less punishing: 96 FPS at 1920x1080 drops to 68 FPS at 2560x1440 (a 29% reduction), then further to 43 FPS at 3840x2160 (a 37% reduction from 1440p). The Medium preset shows 78, 56, and 35 FPS across the same resolution ladder, with the min-to-max frame range tightening from 67-90 at 1080p to 48-64 at 1440p and finally 30-40 at 4K.

The data indicates that the Intel Arc B370's pixel throughput capabilities—rated at 48.00 GPixel/s—are simply insufficient for 4K rendering in this horror title. The GPU's texture rate of 96.00 GTexel/s and FP32 performance of 6.144 TFLOPS create a bottleneck that becomes increasingly apparent as pixel count grows. With only 1280 shading units and 20 ROPs, the architecture struggles to maintain playable framerates beyond 1440p, and even at 1080p Ultra the average of 40 FPS suggests the graphics pipeline is saturated.

How This Combo Ranks

The combination of AMD Ryzen 7 5800X and Intel Arc B370 ranks 2688th out of 2928 tested combos in Downfall, placing it in the lowest 8.2% of all systems evaluated. This ranking is heavily influenced by the GPU's performance class, as the Arc B370 sits in the 5th percentile of all GPUs with an average benchmark score of just 1184.

The GPU's nearest rivals in the synthetic 3DMark Steel Nomad DX12 benchmark—the ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, AMD Radeon HD 7650M, and AMD FirePro M2000—are all legacy or low-power mobile parts, underscoring the Arc B370's entry-level positioning. The deltaPct values are remarkably tight, ranging from -0.7% to +1.4%, indicating that the Arc B370 sits in an extremely crowded performance tier where minute differences separate products.

In contrast, the Ryzen 7 5800X is a high-performing desktop processor from AMD's 5000 series, built on the Zen 3 (Vermeer) architecture at 7 nm. Its 81st percentile ranking among all CPUs, with an average benchmark score of 29123, places it firmly in mid-to-upper tier territory. The nearest CPU rivals—Intel Core Ultra 5 135H, Intel Xeon Phi 7210, Intel Core i5-13500HX, and AMD Ryzen 5 5600XT—all fall within a 0.6% window of the 5800X's average score, demonstrating that the processor is well-matched against contemporary alternatives.

The massive disparity between CPU and GPU performance tiers explains the combo's low ranking. While the 5800X can feed frames rapidly, the Arc B370's limited shading units, TMUs, and ROPs cap the output at levels more typical of integrated graphics or older discrete parts. The data indicates that this combination is severely GPU-limited, with the processor's capabilities largely wasted in this specific game.

Measured FPS Breakdown

At 1920x1080, the resolution most likely to yield playable results, the average framerates span from 96 FPS at Low settings down to 40 FPS at Ultra. The Medium preset delivers 78 FPS with a recorded range of 67 to 90 FPS, while High settings produce 64 FPS. This represents a 58% performance drop from Low to Ultra, highlighting the significant cost of enabling higher-quality rendering features.

Moving to 2560x1440, the average framerates shift downward substantially: Low settings produce 68 FPS, Medium yields 56 FPS with a 48-64 FPS range, High drops to 46 FPS, and Ultra falls to 29 FPS. The step from 1080p to 1440p costs between 26% (Low) and 31% (Ultra) of the average framerate, showing that the GPU's pixel throughput becomes increasingly strained as resolution climbs.

At 3840x2160, the results are largely disappointing for smooth gameplay. Low settings manage 43 FPS, Medium produces 35 FPS with a 30-40 FPS range, High drops to 29 FPS, and Ultra sinks to 18 FPS. The 4K doubling of pixel count from 1440p exacts a heavy toll, with framerates falling by 37% (Low), 38% (Medium), 37% (High), and 38% (Ultra) respectively.

The min and max FPS data available only for Medium settings across all three resolutions provides insight into frame pacing. At 1080p, the 67-90 FPS range represents a 34% spread from minimum to maximum, suggesting notable frame time variance. At 1440p, the 48-64 FPS range tightens to a 33% spread, while at 4K, the 30-40 FPS range narrows to a 33% spread, indicating consistent relative variance regardless of resolution.

CPU Role

The AMD Ryzen 7 5800X brings substantial processing resources to this combination, featuring 8 cores and 16 threads based on the Zen 3 architecture manufactured at 7 nm by TSMC. Its base clock of 3.80 GHz can boost up to 4.70 GHz, and the processor includes 32 MB of L3 cache alongside 64 KB L1 and 512 KB L2 per core. This configuration delivers strong synthetic benchmark scores, including a Cinebench R23 multi-core result of 15476 and single-core score of 1574.5.

However, the measured FPS data in Downfall suggests that the CPU's capabilities are not the determining factor in this game's performance. The consistent frame rate drops across resolution increases—from 64 to 46 to 29 FPS at High settings—follow the GPU's rendering load pattern rather than any CPU-related bottleneck. If the 5800X were limiting performance, we would expect to see smaller differences between resolutions as GPU load increases while CPU work remains constant.

The processor's 3DMark multi-threaded scores reinforce its strength: 7586 with 16 threads, 6035 with 8 threads, 3543 with 4 threads, and 1846 with 2 threads. The single-thread score of 943 and Geekbench single-core result of 2032 indicate robust per-core performance, which is important for a horror title that may rely on single-threaded game logic. The PassMark physics score of 1364 further confirms the CPU's capability to handle game physics calculations without becoming a bottleneck.

With a TDP of 105 W and support for DDR4 memory at 51.2 GB/s bandwidth, the 5800X provides a solid foundation. Yet the Arc B370's integrated graphics design, with system-shared memory and a 25 W TDP, means the GPU operates within tight power and bandwidth constraints. The data indicates that upgrading the GPU would yield far greater performance gains in Downfall than any CPU change, as the 5800X's 81st percentile ranking leaves considerable headroom for a more capable graphics solution.

Settings Recommendations

Based on the measured FPS data, the optimal configuration for Downfall with this hardware combination is 1920x1080 at Medium settings, which delivers a 78 FPS average with a minimum of 67 FPS and maximum of 90 FPS. This setting provides a 22% improvement over High settings (64 FPS) while maintaining visual quality above the Low preset, which achieves 96 FPS but likely sacrifices too much graphical fidelity.

For users prioritizing smooth performance above all else, 1920x1080 at Low settings produces the highest framerate of any tested configuration at 96 FPS. This is the only setting that approaches high-refresh-rate territory, though the visual trade-offs may be significant for a horror game where atmosphere and environmental detail contribute to the experience.

At 2560x1440, Medium settings provide the most balanced experience with a 56 FPS average and a minimum of 48 FPS, keeping gameplay within acceptable bounds. The High preset at 1440p drops to 46 FPS, which is still playable but shows signs of strain, while Ultra at 29 FPS falls below the threshold for smooth gameplay.

The 4K resolution is only viable at Low settings, where 43 FPS average makes the game technically playable, though the visual compromises may undermine the purpose of running at such high resolution. Medium at 4K produces 35 FPS with a 30 FPS minimum, which could be acceptable for slower-paced horror gameplay but risks noticeable stuttering. High and Ultra at 4K (29 and 18 FPS respectively) are not recommended for active gameplay.

The data suggests that the Arc B370's 6.144 TFLOPS FP32 performance and 96.00 GTexel/s texture rate are best utilized at 1080p with Medium settings, where the GPU can maintain consistent frame delivery without hitting the pixel fill rate limits that plague higher resolutions. The 40 ROPs available for rasterization are adequate for 1080p Medium workloads but become the binding constraint as resolution increases, making 1440p and 4K gameplay marginal at best.
