Downfall

# Downfall with AMD Ryzen 7 5800XT + NVIDIA GeForce GTX 1660 Ti

The pairing of AMD's Ryzen 7 5800XT with NVIDIA's GTX 1660 Ti in Downfall produces a system that ranks 1515th out of 1741 tested combos, placing it in the lower-mid tier of the database. The measured frame rates tell a story of a GPU-bound experience at higher resolutions, with the CPU showing surprising headroom as settings drop. This analysis breaks down how the 8-core, 16-thread processor interacts with the 6 GB Turing-based card across four resolutions and four quality presets.

Resolution Scaling

The FPS drop from 1080p to 4K reveals a classic GPU-limited scenario. At Low settings, the system delivers 150 FPS at 1920x1080, falling to 105.9 FPS at 2560x1440 — a 29.4% reduction — and then dropping further to 64.9 FPS at 3840x2160, which is 56.7% lower than the 1080p figure. This steep decline indicates that pixel throughput, rather than geometry or CPU logic, becomes the bottleneck as resolution climbs.

The pattern holds across other presets. At High settings, the drop from 1080p (98.6 FPS) to 1440p (68.9 FPS) is 30.1%, and the slide to 4K (43.1 FPS) represents a 56.3% loss from 1080p. Interestingly, the percentage drops are remarkably consistent across Low, Medium, and High — all hovering around the 29-31% range for 1440p and 55-57% for 4K. This uniformity suggests that the GTX 1660 Ti's 192-bit memory bus and 288.0 GB/s bandwidth are the limiting factors, as the workload scales predictably with pixel count.

Ultra settings tell a different story. At 1080p, Ultra yields 63.4 FPS, which drops to 47.2 FPS at 1440p (a 25.6% decrease) and 27.8 FPS at 4K (a 56.2% decrease from 1080p). The smaller 1440p drop implies that at Ultra, the GPU's shading units (1536) and texture units (96) become saturated even at lower resolutions, making the transition to 1440p less costly relative to the already-heavy workload.

CPU Role

The Ryzen 7 5800XT brings substantial compute resources to the table: 8 cores, 16 threads, with a 3.80 GHz base and 4.80 GHz boost clock. Its Cinebench R23 multicore score of 23794 places it at the 86th percentile among all CPUs, with nearest rivals like the AMD Ryzen 7 7840H (avg score 29868) sitting just 0.3% ahead. This processor is not the weak link in Downfall.

Benchmark results indicate that at 1080p Low, the system hits 150 FPS, which is likely approaching the CPU's practical limit for this game engine. The 3dmark single-thread score of 959 and 2-thread score of 1879 show solid per-core performance, adequate for a 2016 horror title that likely uses 2-4 threads primarily. The 3dmark 8-thread score of 6141 versus max-threads score of 7680 suggests that Downfall may not fully utilize all 16 threads, but the processor's headroom means frame rates are dictated by the GPU even at lower resolutions.

The 32 MB L3 cache and DDR4 memory support with 51.2 GB/s bandwidth provide ample data throughput for game assets. The CPU's passmark multithread score of 27988, which is 0.1% ahead of the AMD Ryzen 7 PRO 5755GE (29740 avg), reinforces that this is a mid-range-plus processor that won't constrain the GTX 1660 Ti in most scenarios.

GPU Role

The GTX 1660 Ti, with its 6 GB GDDR6 memory and 192-bit bus, delivers 288.0 GB/s of bandwidth — a figure that becomes critical in Downfall's higher-resolution presets. The GPU's 55th percentile ranking among all GPUs, with an average benchmark score of 13925, places it near the AMD Radeon RX 570X (13871, 0.4% behind) and NVIDIA RTX A2000 Mobile (13821, 0.8% behind). This is a mid-range card, and the measured frame rates reflect that positioning.

The GPU's boost clock of 1770 MHz and 5.437 TFLOPS FP32 performance are sufficient for 1080p gaming, but the data shows the card struggling at 4K. At 4K Ultra, the system manages only 27.8 FPS — a playable-but-not-smooth experience. The 48 ROPs and 84.96 GPixel/s pixel fill rate are modest by modern standards, which explains the steep scaling losses at 4K.

The memory subsystem deserves scrutiny. With 6 GB of GDDR6, the card has enough capacity for most 1080p and 1440p textures, but the 12 Gbps effective memory speed and 192-bit interface create a bandwidth ceiling. The consistent ~56% FPS drop from 1080p to 4K across all settings suggests that memory bandwidth, not compute, is the primary limiter — as pixel count quadruples, the bandwidth requirement outpaces what the 288.0 GB/s can sustain.

How This Combo Ranks

At rank 1515 out of 1741 combos, this pairing sits in the 13th percentile of all tested configurations. This low ranking is driven by the GPU's modest performance ceiling rather than CPU inadequacy — the Ryzen 7 5800XT's 86th percentile CPU ranking versus the GTX 1660 Ti's 55th percentile GPU ranking highlights the imbalance.

The combo's measured frame rates at 1080p Medium (120.9 FPS) and High (98.6 FPS) are respectable for a horror title, but the 4K numbers (43.1 FPS High, 27.8 FPS Ultra) fall below the 60 FPS threshold that most gamers target. Compared to combos with higher rankings, this system would struggle in 4K scenarios but remain competitive at 1080p. The gap between CPU and GPU capability suggests that upgrading the graphics card would yield significant gains, while the processor has headroom for a more powerful GPU.

Settings Recommendations

Based on the measured rows, the optimal experience balances visual fidelity against frame rate consistency. At 1920x1080, Medium settings (120.9 FPS) provide a comfortable margin above 60 FPS, while High (98.6 FPS) still maintains excellent smoothness. Ultra (63.4 FPS) barely clears the 60 FPS bar, making it viable for players who prioritize image quality.

At 2560x1440, Medium (86.7 FPS) and High (68.9 FPS) are both playable, but Ultra (47.2 FPS) dips below 60 FPS. For 1440p users, Medium offers the best balance of quality and performance. At 3840x2160, only Low (64.9 FPS) achieves 60 FPS, while Medium (54.7 FPS) and High (43.1 FPS) require frame rate tolerance, and Ultra (27.8 FPS) is not recommended for smooth gameplay.

The data suggests that Downfall's preset scaling is non-linear — the jump from High to Ultra costs roughly 36% performance at 1080p (from 98.6 to 63.4 FPS) and 35% at 1440p (68.9 to 47.2 FPS), making Ultra a premium option that many users will skip.

Measured FPS Breakdown

At 1920x1080, the system delivers 150 FPS on Low, 120.9 FPS on Medium, 98.6 FPS on High, and 63.4 FPS on Ultra. The progression shows diminishing returns — going from Low to Medium costs 19.4% performance, Medium to High costs 18.4%, and High to Ultra costs 35.7%.

At 2560x1440, the figures are 105.9 FPS (Low), 86.7 FPS (Medium), 68.9 FPS (High), and 47.2 FPS (Ultra). The percentage losses from 1080p are consistent at approximately 29-30% for Low, Medium, and High, with Ultra showing a slightly lower 25.6% drop.

At 3840x2160, the system achieves 64.9 FPS (Low), 54.7 FPS (Medium), 43.1 FPS (High), and 27.8 FPS (Ultra). The 4K Low figure is remarkable — it's higher than the 1080p Ultra number (63.4 FPS), demonstrating that settings have a larger impact than resolution in this configuration. The 4K Ultra result of 27.8 FPS is the only sub-30 FPS measurement in the dataset.

FAQ

Q: Is the Ryzen 7 5800XT bottlenecking the GTX 1660 Ti in Downfall?

A: No. The CPU's 86th percentile ranking and high benchmark scores (Cinebench R23 multicore 23794) far exceed the GPU's 55th percentile performance. The consistent FPS drops across resolutions indicate GPU limitation, not CPU constraint.

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

A: 1920x1080 offers the most headroom, with Medium (120.9 FPS) and High (98.6 FPS) both providing smooth gameplay. At 2560x1440, Medium (86.7 FPS) is viable, but 3840x2160 only reaches 60 FPS on Low settings.

Q: How does the GTX 1660 Ti compare to its nearest rivals in synthetic benchmarks?

A: The GPU's average benchmark score of 13925 is 0.4% ahead of the AMD Radeon RX 570X (13871) and 0.8% ahead of the NVIDIA RTX A2000 Mobile (13821), but 0.7% behind the NVIDIA Tesla K10 (14029).

Q: Can this system handle 4K gaming in Downfall?

A: Only at Low settings (64.9 FPS). Medium drops to 54.7 FPS, High to 43.1 FPS, and Ultra to 27.8 FPS. Players seeking 4K with higher quality presets would need a more powerful GPU.

Q: What CPU benchmarks indicate the processor's headroom for gaming?

A: The 3dmark 8-thread score of 6141 versus max-threads score of 7680 shows the CPU has additional throughput available. The single-thread score of 959 and passmark single-thread score of 3538 confirm strong per-core performance for game logic.

Q: How does the combo's rank of 1515 out of 1741 reflect its capability?

A: The low rank is primarily due to the GPU's mid-range positioning. The system performs well at 1080p (all settings above 63 FPS) but struggles at higher resolutions, which drags down its overall standing among tested combos.
