Downfall

Resolution Scaling

The measured FPS data for Downfall shows a clear and steep scaling curve as resolution increases. At 1080p with High settings, this combo averages 132 FPS. Moving to 1440p drops that to 93.3 FPS, a 29.3% reduction. Pushing to 4K High yields 57 FPS, which is 56.8% below the 1080p figure. This pattern indicates that the AMD Radeon RX 6650 XT is the primary limiting factor at higher resolutions, as the frame rate penalty from 1080p to 4K is substantial and consistent across all settings presets.

The Low preset tells a similar story, but with higher absolute numbers. At 1080p Low, the combo reaches 199 FPS. At 1440p Low, it falls to 139.9 FPS, and at 4K Low, it still manages 87.8 FPS. The gap between 1080p and 4K Low is 55.9%, almost identical to the High preset's 56.8% drop. This consistency suggests the scaling is resolution-bound rather than settings-bound; the GPU's rendering load scales predictably with pixel count regardless of the quality preset.

Medium settings show 164.7 FPS at 1080p, 117.8 FPS at 1440p, and 73.4 FPS at 4K. The drop from 1080p to 1440p is 28.5%, and from 1440p to 4K is 37.7%. Ultra is the most demanding tier, with 82.1 FPS at 1080p, 58.2 FPS at 1440p, and 34.4 FPS at 4K. The Ultra preset's 4K result is below the 60 FPS threshold, indicating that this combination is not suitable for maxed-out 4K play.

The limiting component shifts depending on resolution. At 1080p, the Ryzen 5 3600's six cores and twelve threads can keep up with the GPU's output, as evidenced by the large FPS headroom at Low and Medium. At 4K, the GPU's 8 GB VRAM and 128-bit memory bus become the bottleneck, with even Medium settings dropping to 73.4 FPS. The data shows that 1440p is the practical ceiling for this pairing, as it maintains playable frame rates across all presets except Ultra.

Settings Recommendations

For 1440p gaming, which appears to be the sweet spot for this combination, the High preset offers the best balance. At 93.3 FPS, it provides smooth gameplay for a horror title where responsiveness matters. The Medium preset at 117.8 FPS gives more headroom, but the visual fidelity loss in a genre that relies on atmosphere and detail may not be worth the 26.3% frame rate increase. Ultra at 1440p drops to 58.2 FPS, which is marginal for a game that may feature sudden action sequences.

At 1080p, the recommendation shifts. High at 132 FPS is excellent, but Medium at 164.7 FPS offers a significant boost with minimal graphical compromise. Low at 199 FPS is excessive for this genre; the extra frames beyond 144 Hz are unlikely to be perceptible on most displays, and the visual downgrade is severe. Ultra at 82.1 FPS is playable but represents a 37.8% drop from High, which is a steep price for marginal improvements.

At 4K, the data is clear: stick to Low or Medium. Low at 87.8 FPS is the only preset that comfortably exceeds 60 FPS. Medium at 73.4 FPS is still playable, but High at 57 FPS and Ultra at 34.4 FPS fall below the smoothness threshold. For a horror game that often uses darkness and shadow to build tension, the Low preset's reduced effects may actually help visibility, but Medium provides a better compromise between atmosphere and performance.

The measured rows suggest that the Ultra preset is not a viable option at any resolution above 1080p for this combo. At 1440p it barely holds 58.2 FPS, and at 4K it collapses to 34.4 FPS. The performance cliff between High and Ultra is steep: 36.3% at 1080p, 37.6% at 1440p, and 39.7% at 4K. This indicates that the Ultra preset introduces rendering features that disproportionately tax the GPU's 2048 shading units and 64 ROPs.

How This Combo Ranks

This pairing of AMD Ryzen 5 3600 with AMD Radeon RX 6650 XT ranks 1139 out of 1741 tested combos in Downfall. That places it in the lower third of the database, which may surprise given the individual component scores. The GPU sits at the 72nd percentile among all GPUs, and the CPU at the 76th percentile among all CPUs, yet the combined result is dragged down by the game's specific demands.

The rank suggests that Downfall is particularly sensitive to one component class more than the other. The CPU's nearest rival, the Intel Core i5-11400, scores nearly identically with a deltaPct of -0.1, meaning the 3600 edges it out by a hair. The GPU's nearest rival, the AMD Radeon RX 6800M, shows a deltaPct of 0.0, indicating a perfect tie in average benchmark score. Despite these strong individual showings, the combo's rank implies that other pairings at similar price points achieve better frame rates in this specific title.

The 1741-combo database includes many high-end configurations, so a rank of 1139 means approximately 65% of tested combinations outperform this one. This is not a condemnation of the hardware, but rather a reflection of where it sits in the performance hierarchy. The Ryzen 5 3600 was released in 2019, and the RX 6650 XT in 2022, so they represent mid-range options from their respective generations.

For context, the CPU's average benchmark score of 18129 is within 0.3% of its nearest rivals, meaning the 3600 is perfectly competitive for its class. The GPU's average score of 29024 is similarly close to its rivals. The combo's rank in Downfall, therefore, likely reflects the game's optimization for newer architectures or higher-end hardware rather than any deficiency in this specific pairing.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with the Navi 23 chip. Its 8 GB of GDDR6 memory on a 128-bit bus provides 280.3 GB/s of bandwidth, which becomes a critical factor in Downfall's 4K performance. The memory clock runs at 2190 MHz, effectively 17.5 Gbps, and the GPU's base clock is 2055 MHz with a boost clock of 2635 MHz and a game clock of 2410 MHz.

The GPU's 2048 shading units, 128 TMUs, and 64 ROPs deliver a pixel rate of 168.6 GPixel/s and a texture rate of 337.3 GTexel/s. The FP32 performance is 10.79 TFLOPS, which is modest by modern standards but adequate for a horror game from 2016. The 32 ray accelerators support DirectX 12 Ultimate, though Downfall predates widespread ray tracing adoption, so this feature is unlikely to impact results.

The 4K High result of 57 FPS shows the GPU's limits. The 8 GB VRAM is sufficient for the game's textures, but the 128-bit memory bus creates bandwidth constraints at higher resolutions. The 280.3 GB/s bandwidth is a bottleneck when the render target grows from 1080p to 4K, which explains the steep FPS drops. The GPU's percentile rank of 72 places it above average, but its nearest rival, the AMD Radeon RX 6800M at a deltaPct of 0.0, shows it is evenly matched with a mobile flagship.

The passmark G3D score of 17166 and the 3DMark Steel Nomad DX12 score of 1859 provide synthetic confirmation of its mid-range positioning. The Geekbench scores — 109922 Metal, 87548 OpenCL, and 93769 Vulkan — indicate the GPU handles compute workloads competently. For Downfall specifically, the GPU's role is dominant, as evidenced by the consistent resolution scaling across all presets.

CPU Role

The AMD Ryzen 5 3600 features six cores and twelve threads based on the Zen 2 architecture, manufactured on TSMC's 7 nm process. Its base clock is 3.60 GHz with a boost clock of 4.20 GHz, and it draws 65 W TDP. The 32 MB shared L3 cache provides ample fast storage for game data, and the dual-channel DDR4 memory support with 51.2 GB/s bandwidth is adequate for this pairing.

The CPU's benchmark scores show strong multithreaded performance. Cinebench R23 multicore reaches 15045, and Passmark multithread scores 17700. Single-thread performance is more modest: Cinebench R23 singlecore scores 2124, and Passmark single-thread scores 2562. In Downfall, the single-thread performance is likely the more relevant metric, as horror games often rely on a primary gameplay thread.

The CPU's percentile rank of 76 places it above three-quarters of all CPUs tested. Its nearest rival, the Intel Core i5-11400, scores 18150 in average benchmark versus the 3600's 18129, a deltaPct of -0.1, meaning the 3600 is essentially tied with its direct competitor. The AMD Ryzen 5 7535HS at 18101 (deltaPct 0.2) and the Ryzen 5 1600 at 18158 (deltaPct -0.2) round out a tightly clustered group.

In Downfall, the CPU's role is secondary to the GPU, but it must keep up with the render thread. The 1080p Low result of 199 FPS confirms the CPU can feed the GPU efficiently at high frame rates. The 3DMark scores — 4605 for 16 threads, 4603 for max threads, and 696 for single thread — show scaling that tops out around 8 threads, which aligns with the 6-core/12-thread configuration. The Passmark physics score of 1152 indicates solid game physics processing capability.
