Downfall

# Downfall with AMD Ryzen 9 5900X + Intel Arc B570

The AMD Ryzen 9 5900X paired with the Intel Arc B570 delivers a mid-range performance profile in Downfall, a 2016 horror title that remains sensitive to both CPU and GPU scaling. The combo ranks 2988th out of 3716 tested combinations, placing it in the lower-mid tier of the benchmark database. Across twelve measured configurations spanning three resolutions and four quality presets, the system produces average frame rates from 30 FPS at 4K Ultra to 163 FPS at 1080p Low, indicating that playability depends heavily on the chosen settings and resolution. The data suggests a GPU-bound system at higher resolutions, with CPU headroom becoming more apparent as resolution drops.

Resolution Scaling

The measured FPS progression across resolutions reveals a classic GPU-limited scaling pattern. At 1080p High, the combo averages 109 FPS; moving to 1440p High reduces this to 78 FPS, a drop of 31 FPS or approximately 28%; at 4K High, the average falls to 49 FPS, another 29 FPS reduction from 1440p. This consistent ~30 FPS decline per resolution step indicates the Intel Arc B570 is the primary limiting component at High settings, with the Ryzen 9 5900X providing ample headroom even at 1080p.

The Low preset tells a similar story with steeper absolute numbers: 163 FPS at 1080p, 116 FPS at 1440p, and 72 FPS at 4K. The percentage drops between 1080p and 1440p (29%) and between 1440p and 4K (38%) are slightly larger than at High, suggesting that at lower graphics loads, the GPU still dominates but the CPU begins to matter more at 1080p. The 163 FPS at 1080p Low is the highest figure in the entire dataset, and the fact that it does not exceed ~165 FPS hints at a possible frame cap or engine limitation rather than CPU saturation, given the 5900X's 12-core/24-thread configuration.

Ultra settings present the steepest scaling curve: 68 FPS at 1080p, 49 FPS at 1440p, and just 30 FPS at 4K. The 4K Ultra result is the only sub-40 FPS average in the dataset, and the 20 FPS gap between 1440p and 4K represents a 41% reduction. This pattern confirms that Downfall's Ultra preset imposes rendering costs that scale almost linearly with pixel count, overwhelming the B570's 10 GB GDDR6 buffer and 380.0 GB/s bandwidth at 4K. The 49 FPS at 1440p Ultra is borderline playable, while 30 FPS at 4K Ultra is not.

How This Combo Ranks

The combo's rank of 2988 out of 3716 tested combinations places it in the 20th percentile of all tested systems in Downfall. This rank reflects the entire platform — CPU, GPU, memory, and driver stack — rather than any single component. The Ryzen 9 5900X alone sits in the 87th percentile against all CPUs in synthetic benchmarks, with an average benchmark score of 41376. The Intel Arc B570, however, occupies the 65th percentile against all GPUs, with an average score of 20556. The gap between CPU and GPU percentiles explains why the combo rank is lower than the CPU's standalone standing: the B570 is the weaker link.

Comparing the GPU to its nearest rivals, the Arc B570 (avg score 20556) is virtually tied with the NVIDIA GeForce RTX 3070 Mobile (20534, deltaPct 0.1%) and the Intel Arc A750 (20582, deltaPct -0.1%). It edges out the NVIDIA Quadro M4000M (20480, deltaPct 0.4%) and trails the AMD Radeon R9 M390X (20662, deltaPct -0.5%). These deltas are all within half a percent, indicating that the B570's raw compute performance is comparable to a mobile RTX 3070 and a previous-generation desktop Arc A750, but the measured FPS in Downfall will also depend on drivers and architecture-specific optimizations.

On the CPU side, the Ryzen 9 5900X (avg 41376) sits between the Intel Core Ultra 7 366H (41263, deltaPct 0.3%) and the Intel Core i7-14650HX (41576, deltaPct -0.5%). These rivals are mobile processors, yet the desktop 5900X only leads by 0.3-0.4% over the Ultra 7 parts, suggesting that in synthetic multi-threaded workloads, the 5900X's 12 cores do not translate into a commanding lead over newer mobile chips. In a horror game like Downfall, which likely uses fewer threads, the single-thread score of 941 in 3dmark_single_thread and 3469 in passmark_single_thread becomes more relevant than the 10075 3dmark_max_threads score.

GPU Role

The Intel Arc B570, based on the Xe2-HPG architecture (Battlemage generation), brings 2304 shading units, 144 TMUs, and 80 ROPs to the rendering pipeline. Its boost clock is fixed at 2500 MHz, identical to the base clock, which means no dynamic clock headroom — the GPU operates at a constant frequency under load. The memory subsystem consists of 10 GB GDDR6 on a 160-bit bus, delivering 380.0 GB/s of bandwidth and 2375 MHz memory clock (19 Gbps effective). This bandwidth is modest by modern standards, and Downfall's high-resolution presets stress it heavily.

The B570's pixel rate is 200.0 GPixel/s and texture rate is 360.0 GTexel/s, with FP32 performance of 11.52 TFLOPS. These figures place it in the mid-range segment, and the measured FPS data reflects this. At 1080p Medium, the system averages 133 FPS (min 113, max 153), which is smooth for a horror title. At 4K Medium, the average drops to 59 FPS (min 50, max 68) — playable but with noticeable dips. The 4K Ultra result of 30 FPS aligns with the GPU's raw throughput limits, as the Ultra preset likely adds shadows, reflections, and post-processing effects that multiply the fill rate demands.

The GPU's 65th percentile ranking against all GPUs, with an average benchmark score of 20556, confirms its mid-tier status. The nearest rival data shows the B570 trading blows with the RTX 3070 Mobile and Arc A750 within 0.1%, but the B570's 10 GB VRAM may be insufficient for 4K Ultra textures in Downfall, as evidenced by the 30 FPS result. The GPU's 150 W TDP and dual-slot cooler are appropriate for this performance class, and the PCIe 4.0 x8 interface provides sufficient bandwidth for the 10 GB frame buffer.

Measured FPS Breakdown

At 1920x1080, the dataset includes four settings. Low averages 163 FPS, Medium averages 133 FPS (min 113, max 153), High averages 109 FPS, and Ultra averages 68 FPS. The spread from Low to Ultra is 95 FPS, a 58% reduction, indicating that Downfall's graphics options have a substantial impact at 1080p. The Medium preset's min/max range of 113-153 FPS shows a 40 FPS variance, which could translate to occasional stutter in a horror game where frame pacing matters for atmosphere.

At 2560x1440, Low averages 116 FPS, Medium averages 95 FPS (min 81, max 110), High averages 78 FPS, and Ultra averages 49 FPS. The reduction from 1080p to 1440p is approximately 29% across all presets, consistent with the ~78% pixel count increase (2,073,600 to 3,686,400 pixels). The Medium preset's min of 81 FPS is still comfortably above 60, while Ultra's 49 FPS average sits below the 60 FPS threshold that many players consider the minimum for smooth gameplay.

At 3840x2160, Low averages 72 FPS, Medium averages 59 FPS (min 50, max 68), High averages 49 FPS, and Ultra averages 30 FPS. The 4K pixel count (8,294,400) is 4x that of 1080p, and the FPS scaling is sub-linear due to GPU bottlenecks. The Medium preset's min of 50 FPS is borderline, while Ultra at 30 FPS is effectively unplayable for a game requiring fast reactions. The gap between Low (72 FPS) and High (49 FPS) at 4K shows that even modest quality increases can halve the frame rate at this resolution.

Settings Recommendations

Based on the measured FPS data, the optimal experience depends on the target resolution. At 1080p, the High preset at 109 FPS offers a strong balance of visual quality and performance, while Ultra at 68 FPS is still playable. For players prioritizing smoothness, Medium at 133 FPS (min 113) provides a large margin above 60 FPS, with the min FPS confirming no drops below 113. Low at 163 FPS is only recommended for competitive play or if frame pacing is a concern, as the visual downgrade is significant.

At 1440p, the Medium preset at 95 FPS (min 81) is the clear sweet spot — the min FPS stays above 80, ensuring consistent smoothness. High at 78 FPS is acceptable for most players, but the 49 FPS Ultra average falls below the 60 FPS threshold. Low at 116 FPS remains viable if visual fidelity is less important. The recommendation is Medium for 1440p, as it delivers 95 FPS average with only a 16% reduction from Low, while High costs 18% more performance for the next quality step.

At 4K, the options are limited. Low at 72 FPS is the only preset exceeding 60 FPS, while Medium at 59 FPS (min 50) is borderline — occasional dips to 50 FPS may be noticeable. High at 49 FPS and Ultra at 30 FPS are not recommended for smooth gameplay. For 4K owners, Low is the only reliable choice, with Medium as a compromise for those who accept occasional frame drops. The 10 GB VRAM may also cause texture pop-in at 4K Ultra, although the dataset does not measure this directly.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture (Vermeer codename), manufactured on TSMC's 7 nm process with 8,300 million transistors across a 2x 74 mm² die. Its base clock is 3.70 GHz with a boost clock of 4.80 GHz, and it supports DDR4 memory in dual-channel configuration with 51.2 GB/s bandwidth. The 64 MB L3 cache is substantial and benefits games that access large working sets.

In Downfall, the CPU's role is evident from the FPS scaling at lower resolutions. At 1080p Low, the system hits 163 FPS, which is likely near the engine's ceiling or the GPU's limit at these settings. The CPU's single-thread performance — 941 in 3dmark_single_thread, 1527 in cinebench_r23_singlecore, and 2083 in geekbench_singlecore — is strong for a 2020 processor, and it should not bottleneck a horror game that likely uses 4-8 threads. The 3dmark_4_threads score of 3588 and 3dmark_8_threads score of 6601 indicate solid scaling up to 8 threads, which covers most game workloads.

The CPU's 87th percentile ranking against all CPUs, with an average benchmark score of 41376, places it well above the GPU's 65th percentile. This mismatch means the system is GPU-bound in most Downfall scenarios, particularly at 1440p and 4K. At 1080p with Low settings, the CPU still manages to deliver 163 FPS without becoming the primary limiter, as evidenced by the smooth scaling from 1080p to 1440p at Low (163 to 116 FPS, a 29% drop matching the pixel increase). If the CPU were the bottleneck, the 1080p to 1440p drop would be smaller.

The CPU's nearest rivals — Intel Core Ultra 7 366H, Core Ultra 7 356H, Ryzen AI 5 PRO 440, and Core i7-14650HX — are all mobile processors, and the 5900X leads them by margins of 0.3% to 0.5% in average benchmark score. This narrow lead suggests that for Downfall, the CPU is more than sufficient, and the 12-core count provides headroom for background tasks or streaming without impacting game performance. The 105 W TDP and Socket AM4 compatibility make it a practical choice for a gaming system paired with a mid-range GPU like the B570.
