# Downfall Performance Analysis: AMD Ryzen 7 5800X3D + NVIDIA GeForce RTX 4070

The AMD Ryzen 7 5800X3D paired with the NVIDIA GeForce RTX 4070 delivers a formidable gaming experience in Downfall, a horror title from 2016 that remains demanding on modern hardware. This combo ranks in the 77th percentile of all tested system configurations, sitting at position 862 out of 3,716 combinations tested. The data reveals a system that excels at high refresh rate 1440p gaming while still delivering playable 4K performance, with the CPU's 3D V-Cache architecture and the GPU's Ada Lovelace design working in concert to produce remarkably consistent frame rates across the resolution spectrum.

Resolution Scaling

The measured FPS data shows a clear and predictable scaling pattern as resolution increases, but the magnitude of the performance drop reveals important insights about where the bottleneck lies in this system. At 1080p with High settings, the combo produces 210 FPS, which drops to 150 FPS at 1440p (a 28.6% reduction) and further to 93 FPS at 4K (a 55.7% reduction from the 1080p baseline). This scaling curve is telling — the performance penalty from 1080p to 1440p is substantial, indicating that the GPU is already becoming a limiting factor at 1440p, while the relatively smaller incremental drop from 1440p to 4K (38% reduction) suggests the GPU continues to be the primary constraint throughout.

Looking at Low settings, the pattern becomes even more instructive. At 1080p Low, the system produces 312 FPS, dropping to 223 FPS at 1440p (−28.5%) and 139 FPS at 4K (−55.4%). The almost identical percentage drops at Low settings compared to High settings (28.5% vs 28.6% from 1080p to 1440p, and 55.4% vs 55.7% from 1080p to 4K) strongly suggest that the scaling is resolution-bound rather than settings-bound. When the CPU is less burdened at Low settings, the GPU still shows the same relative performance degradation, indicating that the RTX 4070's 192-bit memory bus and 504.2 GB/s bandwidth become increasingly stressed as pixel count rises.

The Medium settings row provides additional granularity with min/max FPS data. At 1080p Medium, the system averages 256 FPS with a minimum of 217 and maximum of 294, while at 1440p Medium it averages 182 FPS with a range of 155–210, and at 4K Medium it averages 114 FPS with a range of 97–131. The frame time consistency appears to remain relatively stable across resolutions, with the spread between min and max FPS growing slightly larger at higher resolutions — from 77 FPS at 1080p to 55 FPS at 1440p to 34 FPS at 4K in absolute terms, but the relative spread (max/min ratio) actually narrows, suggesting that 4K performance is more consistently GPU-limited rather than experiencing CPU-driven frame spikes.

CPU Role

The AMD Ryzen 7 5800X3D brings an unusual configuration to this gaming workload: 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.40 GHz and boost clock of 4.50 GHz. What sets this chip apart is its 96 MB of shared L3 cache — a massive amount that proves particularly beneficial in gaming scenarios where data locality and cache hits can dramatically reduce memory latency penalties. The CPU's 3Dmark scores paint a picture of strong multi-threaded performance: 7,299 in the 16-thread test and 7,285 in the max-threads test, with the 8-thread score of 5,906 showing that scaling from 8 to 16 threads yields only a 23.4% improvement — typical for a chip with SMT where the additional logical cores provide diminishing returns in most workloads.

In Downfall, a horror game that likely benefits from the CPU's substantial cache given its potentially complex scene loading and AI-driven tension mechanics, the 5800X3D's performance profile in synthetic benchmarks suggests it is more than capable of feeding the RTX 4070 at all tested resolutions. The Cinebench R23 scores of 14,317 multi-core and 1,452 single-core, combined with Geekbench scores of 11,765 multi-core and 2,017 single-core, indicate a processor that excels in both threaded and lightly-threaded tasks. The Passmark multi-thread score of 28,309 and single-thread score of 3,234 (appearing twice in the benchmark data) further confirm this balanced capability.

However, the resolution scaling data tells a nuanced story about the CPU's role. At 1080p Low where the CPU is most likely to be the limiting factor (given that frame rates exceed 300 FPS), the system still achieves 312 FPS, suggesting the 5800X3D has headroom even at extremely high frame rates. The 3D V-Cache architecture, which is not present in the standard Ryzen 5000 series, likely contributes to this performance by reducing the frequency of cache misses that would otherwise force slower memory accesses. The CPU's 80th percentile ranking among all tested CPUs, with an average benchmark score of 27,896, places it in the upper tier of processors, and its nearest rivals show remarkably tight margins: it trails the AMD Ryzen AI 5 PRO 340 by just 0.1% and leads the Intel Core i5-12600KF by 0.3%, while matching the AMD Ryzen 7 6800U and Intel Core i9-10900K essentially exactly (0% and 0.1% deltas respectively).

GPU Role

The NVIDIA GeForce RTX 4070 represents a significant architectural leap with its Ada Lovelace design on TSMC's 5 nm process, packing 35,800 million transistors into a 294 mm² die. The GPU operates at a base clock of 1920 MHz boosting to 2475 MHz, with 5,888 shading units, 184 texture mapping units, and 64 ROPs. The 12 GB of GDDR6X memory on a 192-bit bus provides 504.2 GB/s of bandwidth — a configuration that proves sufficient for Downfall at all tested settings, though the resolution scaling data suggests it becomes the primary limiting factor at 4K.

The GPU's benchmark scores demonstrate strong DirectX performance, with Passmark DirectX 11 scoring 244 and DirectX 12 scoring 103, while the 3DMark Steel Nomad DX12 test yields 3,854. The Geekbench compute scores of 154,858 in OpenCL and 174,152 in Vulkan indicate robust compute capability that extends beyond pure gaming. The Passmark G3D score of 26,927 and GPU compute score of 14,720 further contextualize the GPU's position in the broader landscape. The RTX 4070 ranks in the 81st percentile of all GPUs, with an average benchmark score of 37,648, and its nearest rivals show it sits in a competitive position: it leads the AMD Radeon PRO W6400 by 1.3% and the AMD Radeon RX Vega 56 by 0.4%, while trailing the NVIDIA RTX 4080 Mobile by 1.3% and essentially matching the NVIDIA Tesla P4 (0.1% delta).

In Downfall, the GPU's role becomes increasingly dominant as resolution rises. The measured FPS at 4K Ultra drops to 58 FPS — the only sub-60 FPS result in the entire dataset — which clearly indicates the GPU is struggling to maintain real-time rendering at maximum settings with 4K pixel counts. The GPU's 158.4 GPixel/s pixel rate and 455.4 GTexel/s texture rate provide the raw throughput, but the 192-bit memory bus appears to be the constraint at 4K Ultra, where the combination of high resolution and maximum visual effects demands more bandwidth than the 504.2 GB/s can supply for sustained 60+ FPS performance.

How This Combo Ranks

The combination of the Ryzen 7 5800X3D and RTX 4070 achieves rank 862 out of 3,716 tested combos in Downfall, placing it in the top 23.2% of all system configurations tested. This ranking reflects a system that is decisively above average but not at the very top tier of performance, which makes sense given that both components are strong mid-to-high-end offerings rather than flagship parts. The CPU's 80th percentile ranking and the GPU's 81st percentile ranking are remarkably aligned, suggesting this pairing creates a balanced system where neither component is severely over- or under-powered relative to the other.

The fact that this combo ranks slightly higher in the percentile distribution than either component does individually (77th percentile for the combo vs 80th and 81st for CPU and GPU respectively) is notable. This could indicate that the specific combination of the 5800X3D's large L3 cache and the RTX 4070's Ada Lovelace architecture works particularly well together in Downfall's rendering pipeline, potentially due to the game's horror genre characteristics — frequent scene transitions, dynamic lighting changes, and tension-building visual effects that may benefit from both the CPU's cache efficiency and the GPU's ray tracing and tensor core capabilities (46 RT cores and 184 tensor cores).

The nearest rival comparisons for each component provide context for the combo's positioning. The CPU's closest competitor, the AMD Ryzen AI 5 PRO 340, is separated by just 0.1% in average benchmark score, while the GPU's nearest rival, the NVIDIA Tesla P4, is 0.1% ahead. This suggests that small performance differences in individual components can translate into meaningful rank differences when combined, as the 862nd position out of 3,716 represents a specific sweet spot in the distribution where many similar-performing combinations cluster.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution and desired frame rate. At 1080p, all settings are playable with excellent performance — even Ultra achieves 131 FPS, while Medium delivers 256 FPS and Low reaches 312 FPS. The Medium preset at 1080p appears to offer the best balance for competitive or high-refresh-rate play, with its 256 FPS average and tight 217–294 FPS range providing smooth performance for 144 Hz and 240 Hz displays.

At 1440p, the High preset at 150 FPS represents the sweet spot for most users, offering a significant visual upgrade over Medium's 182 FPS while still maintaining frame rates well above 144 Hz thresholds. The Ultra preset at 94 FPS remains playable but begins to approach the point where motion smoothness could be compromised on high-refresh displays. For users prioritizing maximum visual fidelity, the 4K High preset at 93 FPS provides a solid experience, while 4K Medium at 114 FPS offers even more headroom. The 4K Ultra setting at 58 FPS is the only configuration that dips below 60 FPS, making it the only setting not recommended for smooth gameplay.

The data reveals that the Medium preset consistently provides the most consistent performance across all resolutions, with the smallest relative frame time variance. At 1080p Medium, the min/max range spans 77 FPS (217–294), at 1440p Medium it spans 55 FPS (155–210), and at 4K Medium it spans 34 FPS (97–131). This consistency suggests that Medium settings avoid the extreme GPU stress of Ultra while providing more visual fidelity than Low, making it the most balanced choice for users who want stable frame pacing.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce an average of 312 FPS, Medium produces 256 FPS (with a minimum of 217 and maximum of 294), High produces 210 FPS, and Ultra produces 131 FPS. The progression from Low to Ultra shows a 58% performance penalty at the highest settings, which is substantial but expected given the dramatic visual quality increase.

Moving to 2560x1440, the performance scales down proportionally. Low settings average 223 FPS, Medium averages 182 FPS (155–210 range), High averages 150 FPS, and Ultra averages 94 FPS. The drop from 1080p to 1440p represents a 28.5% reduction at Low, 28.9% at Medium, 28.6% at High, and 28.2% at Ultra — remarkably consistent scaling that indicates resolution is the dominant factor in performance degradation rather than settings complexity.

At 3840x2160, the system shows its limits. Low settings still manage 139 FPS, Medium averages 114 FPS (97–131 range), High averages 93 FPS, and Ultra drops to 58 FPS. The 4K to 1440p scaling shows a 37.7% reduction at Low, 37.4% at Medium, 38% at High, and 38.3% at Ultra — again highly consistent, confirming that the GPU's rendering throughput scales predictably with pixel count across all quality presets. The 4K Ultra result at 58 FPS is the only measured configuration falling below the 60 FPS threshold, making it the sole setting where the system cannot maintain smooth real-time performance.

FAQ

Q: Can this system run Downfall at 4K with maximum settings?

A: At 3840x2160 with Ultra settings, the combo produces an average of 58 FPS, which is slightly below the 60 FPS threshold. While the game is technically playable at this setting, the frame rate drops below what most users consider smooth for a horror game where responsiveness can be critical. The 4K High preset at 93 FPS provides a much more comfortable experience.

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

A: The data shows 2560x1440 as the sweet spot, with the High preset delivering 150 FPS and even Ultra maintaining 94 FPS. This resolution takes advantage of the RTX 4070's 12 GB of GDDR6X memory while avoiding the 4K Ultra performance penalty, and the 5800X3D's 96 MB L3 cache ensures consistently high frame rates across all settings at this resolution.

Q: How does this combo compare to the 4K Medium setting at lower resolutions?

A: The 4K Medium setting at 114 FPS provides higher visual fidelity than 1440p Ultra (94 FPS) while maintaining better frame rates. However, the 1440p High setting at 150 FPS offers a better balance of visual quality and performance, particularly for high-refresh-rate displays where the extra 36 FPS makes a noticeable difference in smoothness.

Q: Is the CPU or GPU the limiting factor at 1080p?

A: At 1080p Low, the system achieves 312 FPS, which is extremely high and suggests the CPU has significant headroom. The 5800X3D's 8 cores and 16 threads, combined with its 96 MB L3 cache, appear sufficient to feed the GPU even at these elevated frame rates. The GPU becomes the clear bottleneck as resolution increases, evidenced by the consistent percentage drops across all settings.

Q: How consistent is the frame pacing across different settings?

A: The Medium preset provides the most consistent frame pacing, with the narrowest relative range between minimum and maximum FPS. At 1080p Medium, the range is 217–294 FPS (77 FPS spread); at 1440p Medium, it is 155–210 FPS (55 FPS spread); and at 4K Medium, it is 97–131 FPS (34 FPS spread). This consistency makes Medium the best choice for users prioritizing smooth, stable frame delivery.
