Downfall

# Downfall with AMD Ryzen 7 5700 + NVIDIA GeForce GTX 1660 Ti

The AMD Ryzen 7 5700 paired with the NVIDIA GeForce GTX 1660 Ti delivers playable performance in Downfall, a 2016 horror title that proves more demanding than its age suggests. This combination ranks 3202nd out of 3716 tested combos, placing it in the lower third of the database, yet the measured frame rates tell a more nuanced story across resolutions and settings than the raw rank implies.

Resolution Scaling

The frame rate drop from 1080p to 4K reveals a system that becomes increasingly GPU-bound at higher resolutions. At Low settings, the transition from 1920x1080 (147 FPS) to 2560x1440 (105 FPS) represents a 28.6% performance loss, while the jump from 1440p to 4K (65 FPS) costs another 38.1%. This progressive decline is steeper than the pixel-count increase would suggest, indicating the GTX 1660 Ti's 6 GB GDDR6 memory and 288.0 GB/s bandwidth are being saturated as resolution climbs.

At Medium settings, the pattern holds but with smaller absolute margins: 120 FPS at 1080p falls to 86 FPS at 1440p (a 28.3% drop), then to 53 FPS at 4K (a 38.4% further decline). The 4K Medium result of 53 FPS with a minimum of 45 and maximum of 61 shows noticeable variance, suggesting the GPU is working near its limits rather than being held back by the CPU. High settings follow a similar curve—99 FPS at 1080p, 70 FPS at 1440p, and 44 FPS at 4K—with the 4K figure dipping below the 60 FPS threshold that many consider the playability baseline.

The Ultra preset tells the most revealing story about the limiting component. At 1080p Ultra, the system manages 62 FPS, but this collapses to 44 FPS at 1440p and just 27 FPS at 4K. The 4K Ultra result is particularly telling: the 27 FPS average represents a 56.5% drop from the 1080p Ultra score, a proportionally larger penalty than seen at lower settings. This suggests that at Ultra, the combination of increased geometry, texture detail, and post-processing effects overwhelms the GTX 1660 Ti's 1536 shading units and 48 ROPs, making the GPU the unequivocal bottleneck.

The scaling behavior across all four settings presets points to a system where the Ryzen 7 5700's 8 cores and 16 threads are not the limiting factor. Even at 1080p Low, where the CPU has the least GPU work to wait on, the 147 FPS result does not suggest processor constraint. The consistent 30-40% performance drops between each resolution step, regardless of settings, are characteristic of a GPU-limited scenario where the graphics card's memory bandwidth and compute throughput dictate the ceiling.

Settings Recommendations

For 1080p displays, the Medium preset at 120 FPS average (minimum 102, maximum 138) provides the best balance of fluidity and visual fidelity. The jump from Low to Medium costs 27 FPS (18.4% reduction) but likely delivers substantially better texture filtering and shadow quality in a horror title where atmosphere matters. High settings at 99 FPS remain playable, but the additional 21 FPS loss from Medium to High is harder to justify when the visual gains in a dark, corridor-heavy game may be subtle.

At 1440p, Medium again emerges as the sweet spot with 86 FPS average (minimum 73, maximum 99). The minimum of 73 FPS stays comfortably above the 60 FPS threshold, providing smooth gameplay during the tense, action-heavy sequences that horror games often deploy. High settings at 70 FPS are acceptable for players who prioritize image quality, but the 16 FPS penalty over Medium is significant. Low at 105 FPS is the choice for competitive or high-refresh-rate play, though the visual compromises in a game designed around atmosphere and dread may diminish the experience.

The 4K picture is more constrained. Medium at 53 FPS (minimum 45, maximum 61) is the only setting that approaches playability, though the minimum frame rate suggests occasional stutter during demanding scenes. High at 44 FPS is borderline, while Low at 65 FPS offers the only 4K option that maintains a consistent 60+ FPS experience. Ultra at 27 FPS is effectively unplayable, and even the most forgiving players would struggle with such low frame rates in a game that relies on responsive controls for its horror set-pieces.

Across all resolutions, Medium represents the best compromise between visual quality and performance for this hardware combination. The GTX 1660 Ti's 6 GB VRAM appears sufficient for Medium textures at all tested resolutions, and the measured frame times at Medium show the most consistency. Players with 1080p monitors can safely choose High settings and still average 99 FPS, but those on 1440p or 4K displays should stick to Medium to maintain smooth gameplay.

CPU Role

The AMD Ryzen 7 5700 brings substantial processing power to this pairing, with 8 cores and 16 threads based on the Zen 3 architecture (Cezanne codename). The processor's 3.70 GHz base clock and 4.60 GHz boost clock, combined with 16 MB of L3 cache, provide ample headroom for a horror game that likely does not heavily utilize more than a few threads. The CPU's benchmark results reinforce this: 3DMark single-thread score of 901, 2-thread score of 1762, and 4-thread score of 3382 show strong scaling through the first four threads, while the 8-thread score of 5585 and max-thread score of 6617 indicate diminishing returns beyond 8 threads.

In Downfall, the CPU's role appears secondary to the GPU across all tested scenarios. The frame rate patterns—consistent 30-40% drops when moving from 1080p to 1440p to 4K at every settings preset—are the signature of a GPU-bound workload. If the CPU were the limiting factor, we would expect to see smaller performance gaps at higher resolutions where the GPU has more work to do per frame. Instead, the scaling suggests the Ryzen 7 5700 is feeding the GTX 1660 Ti as fast as the GPU can process frames.

The CPU's 65 W TDP and 7 nm process node (10,700 million transistors on a 180 mm² die) indicate efficient operation, but these specifications matter less for gaming performance than the architectural efficiency of Zen 3. The processor's Cinebench R23 multicore score of 20655 and single-core score of 2916 place it well above the minimum requirements for modern games. In this specific title, the CPU's 16 threads provide more than enough parallel processing capacity for the game's AI, physics, and game logic, leaving the GPU as the sole bottleneck.

The nearest CPU rivals in benchmark scores—Intel Xeon D-2752TER (25530, -0.1%), AMD Ryzen 5 7640U (25485, +0.1%), AMD Ryzen 5 6600H (25550, -0.1%), and AMD Ryzen 7 5825U (25446, +0.3%)—all fall within 0.3% of the Ryzen 7 5700's average benchmark score of 25517. This clustering suggests that any of these processors would deliver nearly identical frame rates in Downfall when paired with the same GPU, reinforcing that the CPU is not the performance limiter in this configuration.

How This Combo Ranks

The combination of Ryzen 7 5700 and GTX 1660 Ti ranks 3202nd out of 3716 tested combos in Downfall, placing it in the 13.8th percentile of all tested systems. This low rank reflects the GPU's age and tier more than the CPU's capability. The GTX 1660 Ti's percentile rank of 41 among all tested GPUs, combined with the Ryzen 7 5700's 78th percentile among CPUs, creates a pairing where the graphics card drags the overall system ranking down despite a strong processor.

The GPU's nearest rivals in benchmark scores—AMD Radeon 540 (7673, +0.7%), AMD Radeon Pro WX 3100 (7580, +1.9%), AMD Radeon R7 250 (7557, +2.2%), and Intel Arc A310 (7550, +2.3%)—all score within 2.3% of the GTX 1660 Ti's average of 7723. This tight grouping indicates that the GTX 1660 Ti sits at a performance tier where small architectural differences can shift rankings, yet in Downfall specifically, the measured frame rates show the card delivering playable results at 1080p and 1440p, with 4K limited to lower settings.

The combo rank of 3202 out of 3716 suggests that most tested systems outperform this pairing in Downfall. However, the rank alone does not capture the playability picture: at 1080p Medium, this system delivers 120 FPS, which is well above the 60 FPS target most players seek. The rank reflects the database's inclusion of many higher-end GPUs, not a deficiency in this specific combination for this specific game. Players with 1080p monitors will find this system perfectly adequate, while those with 4K displays should adjust expectations accordingly.

GPU Role

The NVIDIA GeForce GTX 1660 Ti, based on the TU116 chip with Turing architecture, serves as the primary performance determinant in this pairing. The card's 6 GB of GDDR6 memory on a 192-bit bus provides 288.0 GB/s of bandwidth, which proves adequate for 1080p and 1440p gaming but becomes a limiting factor at 4K. The GPU's 1500 MHz base clock and 1770 MHz boost clock, combined with 1536 shading units, 96 TMUs, and 48 ROPs, deliver a raw compute throughput of 5.437 TFLOPS FP32.

The card's benchmark results show its positioning: 3DMark Steel Nomad DX12 score of 1061, PassMark G3D score of 12871, and Geekbench OpenCL score of 51029. These synthetic benchmarks place the GTX 1660 Ti in the 41st percentile among all tested GPUs, confirming its mid-range status. The GPU's 12 nm process node (6,600 million transistors on a 284 mm² die) means it operates at a 120 W TDP, requiring a 300 W suggested power supply—modest by modern standards.

In Downfall, the GTX 1660 Ti's memory subsystem appears to be the critical factor. The VRAM's 288.0 GB/s bandwidth and 6 GB capacity dictate how well the card handles higher resolutions and settings. At 4K Ultra, the 27 FPS result likely stems from both bandwidth saturation and VRAM capacity limits, as the card struggles to feed its 1536 shading units with texture data at that resolution. The 4K Medium result of 53 FPS, while better, still shows the card working at its limits, as evidenced by the 45 FPS minimum.

The GPU's PassMark DirectX scores—DirectX 9 at 190, DirectX 10 at 66, DirectX 11 at 103, and DirectX 12 at 51—indicate that Downfall's rendering workload aligns with the card's DX11 strengths. The game's 2016 release date means it likely uses DX11-era rendering techniques, which the GTX 1660 Ti handles efficiently. The card's support for DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4 ensures compatibility with modern API features, though Downfall may not leverage them extensively.

Measured FPS Breakdown

At 1920x1080, the system demonstrates strong performance across all settings. Low settings produce 147 FPS average, Medium delivers 120 FPS (minimum 102, maximum 138), High achieves 99 FPS, and Ultra manages 62 FPS. The 85 FPS spread between Low and Ultra shows the GPU's capability at this resolution, with even the most demanding preset remaining playable. The Medium preset's minimum of 102 FPS indicates consistent frame delivery without dips below the 100 FPS mark.

Moving to 2560x1440, performance drops predictably. Low settings average 105 FPS, Medium delivers 86 FPS (minimum 73, maximum 99), High reaches 70 FPS, and Ultra falls to 44 FPS. The Medium preset remains the sweet spot with its minimum of 73 FPS ensuring smooth gameplay. The 19 FPS gap between Low and Medium, and the 16 FPS gap between Medium and High, show reasonable scaling, but the 26 FPS drop from High to Ultra becomes problematic, pushing the experience below the 60 FPS threshold.

At 3840x2160, the GTX 1660 Ti struggles to maintain playable frame rates at higher settings. Low settings average 65 FPS, Medium delivers 53 FPS (minimum 45, maximum 61), High achieves 44 FPS, and Ultra drops to 27 FPS. The Medium preset's 45 FPS minimum suggests occasional stuttering during intense scenes, while the High and Ultra results fall below acceptable playability for most users. Only Low settings at 65 FPS provide a consistently smooth 4K experience, though the visual compromises may undermine the horror atmosphere that benefits from higher detail.

The complete frame rate table across all tested configurations shows a clear pattern: the GTX 1660 Ti excels at 1080p, handles 1440p adequately at Medium settings, and requires Low settings at 4K for playable performance. The Ryzen 7 5700 provides sufficient CPU headroom at all resolutions, never appearing as the bottleneck in this pairing. Players seeking the best experience should prioritize 1080p Medium or High settings, where this combination delivers smooth, immersive gameplay in Downfall's tense horror environments.
