Q: What is the best average FPS achieved by this combo in Downfall, and at what settings?

A: The highest recorded average is 147.1 FPS at 1920x1080 with Low settings. The most demanding configuration, 3840x2160 Ultra, drops to 27.8 FPS average.

Q: How does the combo rank overall in Downfall among tested combinations?

A: This pairing ranks 1,529 out of 1,741 tested combos in Downfall. That puts it in the lower portion of the field, though the data shows it remains playable at several settings.

Q: Does the GTX 1660 SUPER support modern graphics APIs relevant to Downfall?

A: Yes. The GPU supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. Its Turing architecture and 12 nm process node from TSMC underpin these capabilities.

Q: What memory configuration does the GTX 1660 SUPER use, and how does that affect performance?

A: It uses 6 GB of GDDR6 memory on a 192-bit bus with 336.0 GB/s bandwidth. Memory clocks run at 1750 MHz, yielding 14 Gbps effective. This bandwidth is a key factor in the measured FPS differences across resolutions.

GPU Role

The NVIDIA GeForce GTX 1660 SUPER is the sole graphics engine here, and its specifications dictate the performance envelope in Downfall. The GPU's base clock is 1530 MHz with a boost clock of 1785 MHz, built on the TU116 chip with 1,408 shading units, 88 TMUs, and 48 ROPs. Pixel rate reaches 85.68 GPixel/s, while texture rate hits 157.1 GTexel/s. The FP32 compute throughput is 5.027 TFLOPS, with FP16 at 10.05 TFLOPS (2:1). These figures explain why the card handles 1080p and 1440p with relative ease but struggles at 4K Ultra.

The 6 GB GDDR6 frame buffer is a critical constraint. At 3840x2160, the card delivers 43.4 FPS on High, 55.7 on Medium, and 62.9 on Low — but Ultra falls to 27.8 FPS. The bandwidth of 336.0 GB/s, driven by a 192-bit bus and 1750 MHz memory clock (14 Gbps effective), is sufficient for lower resolutions but becomes a bottleneck as pixel count rises. The 12 nm process node from TSMC and 6,600 million transistors highlight the GPU's age; it launched in October 2019 with a 125 W TDP and dual-slot cooler. The card's passmark G3D score of 12,699 and DirectX 11 score of 104 reflect its mid-range positioning, which aligns with the measured FPS data showing playable but not exemplary 4K performance.

How This Combo Ranks

In Downfall, this combination of AMD Ryzen 7 5800X3D and NVIDIA GeForce GTX 1660 SUPER ranks 1,529 out of 1,741 tested combos. That places it near the bottom quartile of all pairings, which is expected given the GPU's 55th percentile standing among all GPUs. The CPU, by contrast, sits at the 83rd percentile of all CPUs — a significant mismatch that suggests the graphics card is the limiting factor.

The ranking reflects real measured performance, not synthetic estimates. The data shows that while the CPU is capable of feeding the GPU at lower resolutions, the GTX 1660 SUPER cannot maintain high frame rates at 4K Ultra. At 1920x1080, the combo achieves 147.1 FPS on Low and 64.2 FPS on Ultra, indicating that the GPU is the primary constraint in demanding settings. At 2560x1440, the spread narrows: 102.8 FPS on Low versus 46.8 FPS on Ultra. The 4K results are telling — 62.9 FPS on Low drops to 27.8 FPS on Ultra, a 55.8% reduction. This rank of 1,529 out of 1,741 is consistent with a mid-range GPU paired with a high-end CPU, where the former dictates overall performance in a horror title like Downfall.

Measured FPS Breakdown

The measured FPS data spans three resolutions and four settings tiers, providing a full picture of this combo's capabilities.

At 1920x1080, the combo delivers its best results. Low settings produce 147.1 FPS average, Medium drops to 119.1 FPS, and High yields 97.9 FPS. Ultra is the outlier at 64.2 FPS — still playable, but a 56.3% reduction from Low. These numbers indicate that at 1080p, the GTX 1660 SUPER is rarely the bottleneck, even with a demanding CPU like the 5800X3D feeding it.

Moving to 2560x1440, performance scales down predictably. Low settings average 102.8 FPS, Medium 89.1 FPS, High 71.3 FPS, and Ultra 46.8 FPS. The gap between Low and Ultra (54.5%) is slightly smaller than at 1080p, suggesting the GPU is becoming more constrained by resolution than by settings. High settings at 1440p remain fluid, but Ultra requires compromises.

At 3840x2160, the card's limitations become stark. Low settings average 62.9 FPS, Medium 55.7 FPS, High 43.4 FPS, and Ultra 27.8 FPS. The Ultra result is the only one below 30 FPS in the entire dataset, and the 35.1 FPS difference between Low and Ultra is the largest absolute spread. The data shows that 4K High is borderline (43.4 FPS), while 4K Ultra is effectively unplayable for smooth gameplay. These measured averages confirm that the GTX 1660 SUPER is best suited for 1080p and 1440p gaming in Downfall, with 4K reserved for Low or Medium settings.

CPU Role

The AMD Ryzen 7 5800X3D provides the processing foundation for this combo, and its capabilities are far above what the GTX 1660 SUPER can utilize in Downfall. This 8-core, 16-thread processor from the 5000 series uses the Zen 3 architecture (codenamed Vermeer) on a 7 nm TSMC process. It operates at a 3.40 GHz base clock and boosts to 4.50 GHz, with a 105 W TDP. The L3 cache is a substantial 96 MB shared, which is a defining feature of this chip, alongside 64 KB L1 and 512 KB L2 per core.

Synthetic benchmarks underscore the CPU's strength. Cinebench R23 multicore scores 24,063, while single-core hits 3,397. Geekbench multicore is 11,061 and single-core 2,116. Passmark multithread reaches 28,309, with single-thread at 3,234. The 3DMark 16-thread score of 7,299 and max-thread score of 7,285 show consistent scaling across thread counts. Its average benchmark score of 26,574 places it just 0.1% above the Intel Core i9-11900K and 0.2% below the AMD Ryzen 5 7600, confirming it remains competitive in 2025.

In Downfall, this CPU has ample headroom. The measured FPS at 1080p Low (147.1 FPS) and 1440p Low (102.8 FPS) indicates the GPU is the limiting factor, not the processor. The CPU's 8 cores and 16 threads handle the game's logic and physics without issue, while the 96 MB L3 cache helps with data-heavy scenarios. However, the CPU's 83rd percentile ranking versus the GPU's 55th percentile creates an imbalance — the 5800X3D could drive far higher frame rates with a more powerful graphics card. This pairing, ranked 1,529 out of 1,741, leaves CPU performance on the table at every resolution and setting tested.
