Downfall

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 2600 is a desktop processor from the 2000 series, built on the Zen architecture and codenamed Pinnacle Ridge. It is produced on a 12 nm process node at GlobalFoundries, with a transistor count of 4,800 million and a die size of 213 mm². The chip offers 6 cores and 12 threads, operating at a base clock of 3.40 GHz and a boost clock of 3.90 GHz. Cache configuration includes 96 KB of L1 per core, 512 KB of L2 per core, and a shared 16 MB L3 cache. Memory support is dual-channel DDR4 with a bandwidth of 46.9 GB/s. The CPU uses PCIe Gen 3 with 16 lanes from the processor itself.

In benchmark terms, the Ryzen 5 2600 posts a Cinebench R23 multi-core score of 11186 and a single-core score of 1579. Its PassMark multithread score is 13160, with a single-thread score of 2239. The average benchmark score sits at 19616, placing it in the 77th percentile among all CPUs. Compared to its nearest rivals, the data shows a tight grouping: it trails the Intel Core i5-1345U by 0.4% and the Intel Core i5-11600KF by 0.6%, while leading the AMD Ryzen 5 7530U by 0.6% and the Intel Core i7-10700F by 0.7%. These deltaPct values indicate that the Ryzen 5 2600 performs essentially on par with a cluster of mid-range processors from both Intel and AMD.

For a horror game like Downfall, the CPU's role is primarily to feed the GPU with draw calls and manage game logic. The 6-core, 12-thread configuration provides reasonable parallelism for modern titles, but the Zen architecture's single-thread performance lags behind newer designs. The measured FPS data shows that at 1080p with Low settings, the combo reaches 178 FPS, which suggests the CPU is not a bottleneck at lower resolutions in this title. However, at Ultra settings across all resolutions, the frame rates drop sharply, indicating that the graphics load becomes the dominant factor. The CPU's 65 W TDP and active production status make it a workable partner for the RX 6600, but the data suggests the pairing is balanced toward GPU-bound scenarios at higher settings.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6600 is part of the Radeon RX 6000 series, built on the RDNA 2.0 architecture and using the Navi 23 chip. It is fabricated on a 7 nm process at TSMC, with 11,060 million transistors and a die size of 237 mm², giving a transistor density of 46.7 million per mm². The GPU has a base clock of 1626 MHz, a boost clock of 2491 MHz, and a game clock of 2044 MHz. Memory operates at 1750 MHz, which translates to 14 Gbps effective. The card features 8 GB of GDDR6 memory on a 128-bit bus, providing a bandwidth of 224.0 GB/s. It includes 1792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. Pixel rate is 159.4 GPixel/s, texture rate is 279.0 GTexel/s, and FP32 performance is 8.928 TFLOPS.

In synthetic benchmarks, the RX 6600 delivers a PassMark G3D score of 15096 and a 3DMark Steel Nomad DX12 score of 1492. Its average benchmark score is 25235, placing it in the 69th percentile among all GPUs. The nearest rivals show very small deltas: the AMD Radeon 890M is exactly 0% apart, the AMD Radeon RX 580 2048SP trails by 0.2%, the AMD Radeon RX 6700M leads by 0.2%, and the NVIDIA GeForce RTX 3060 Ti leads by 0.5%. These margins are negligible in practice, meaning the RX 6600's performance profile is nearly identical to that of these other cards.

For Downfall, the GPU's 8 GB VRAM is sufficient for the game's demands, as evidenced by the measured FPS across settings. At 1080p, the card delivers 117.7 FPS on High and 141.6 FPS on Medium, showing strong headroom. The boost clock of 2491 MHz helps maintain high frame rates at lower resolutions, but at 4K Ultra the average drops to 31.7 FPS, highlighting the GPU's limits under heavy load. The PCIe 4.0 x8 interface provides ample bandwidth for the 8 GB memory pool. The card's TDP of 132 W and dual-slot design are modest, making it a balanced mid-range option that pairs well with the Ryzen 5 2600 in this title.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 5 2600 with the AMD Radeon RX 6600 ranks 1402 out of 1741 tested combos in Downfall. This places the pairing in the lower half of the database, with roughly 80% of tested combinations performing better. The percentile position reflects the mid-range nature of both components: the CPU sits in the 77th percentile among all processors, while the GPU sits in the 69th percentile among all graphics cards. When combined, the overall rank is dragged down by the GPU's relatively lower standing, suggesting that the graphics card is the limiting factor in this pairing.

The rank of 1402 means that most other combinations—whether they use newer CPUs, higher-tier GPUs, or both—achieve higher frame rates in this game. However, the measured FPS data shows that this combo is still playable at many settings. The gap between this combo and the top performers is likely substantial, but the data provided does not include specific deltaPct values for the combo rank itself. What is clear is that the RX 6600's 69th percentile GPU standing constrains the overall result, while the CPU's 77th percentile performance provides adequate support. For users seeking higher ranks, the data suggests upgrading the GPU would yield more benefit than upgrading the CPU, given the CPU's higher relative standing.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1080p, the combo delivers its best results. With Low settings, the average FPS is 178. Medium settings yield 141.6 FPS, High settings produce 117.7 FPS, and Ultra settings drop to 74.3 FPS. The progression from Low to Ultra shows a consistent decline, with Ultra being 58% lower than Low. These numbers indicate that at 1080p, the combo can handle even Ultra settings with playable frame rates, though the jump from High to Ultra costs a significant 43.4 FPS.

Moving to 1440p, the frame rates scale down noticeably. Low settings average 127 FPS, Medium averages 100.8 FPS, High averages 83.8 FPS, and Ultra averages 52.1 FPS. The pattern mirrors 1080p but with a steeper drop at Ultra, which is 59% lower than Low. This resolution still offers smooth gameplay on High settings, but Ultra becomes borderline for fast-paced action.

At 4K (3840x2160), the GPU starts to struggle. Low settings average 77.1 FPS, Medium averages 65 FPS, High averages 49.6 FPS, and Ultra averages 31.7 FPS. The Ultra setting at 4K is barely playable, while Low and Medium remain acceptable. The gap between Low and Ultra at 4K is 45.4 FPS, showing that the GPU's limits are reached at this resolution. Across all resolutions, the delta between Low and Ultra grows as resolution increases, from 103.7 FPS at 1080p to 45.4 FPS at 4K, indicating that the GPU becomes more constrained at higher pixel counts.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS drop from 1080p to 4K reveals which component is the bottleneck. At Low settings, the average FPS falls from 178 at 1080p to 127 at 1440p (a 28.7% drop) and then to 77.1 at 4K (a 39.3% drop from 1440p). At High settings, the progression is 117.7 to 83.8 to 49.6, representing drops of 28.8% and 40.8% respectively. At Ultra settings, the numbers are 74.3, 52.1, and 31.7, with drops of 29.9% and 39.2%.

These percentage drops are relatively consistent across settings, which is a classic sign of GPU-bound scaling. If the CPU were the limiting factor, the frame rates would stay flatter as resolution increases, since the CPU workload remains constant while the GPU workload grows. Instead, the FPS drops roughly 30% from 1080p to 1440p and another 40% from 1440p to 4K, regardless of the quality preset. This pattern indicates that the RX 6600's rendering throughput is the primary constraint.

The CPU's 77th percentile ranking versus the GPU's 69th percentile supports this interpretation. At 1080p Low, the combo reaches 178 FPS, which is high enough to suggest the CPU can push frames when the GPU is not heavily loaded. But as resolution increases, the GPU's pixel fill rate and memory bandwidth become the limiting factors. The 224.0 GB/s memory bandwidth and 159.4 GPixel/s pixel rate are the likely culprits at 4K. This is a GPU-bound scenario, and the data confirms that upgrading the GPU would provide the most significant FPS gains at higher resolutions.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the best experience depends on the resolution target. At 1080p, Ultra settings deliver 74.3 FPS, which is smooth for most players. The drop from High (117.7 FPS) to Ultra (74.3 FPS) is substantial, but the visual quality improvement may justify it. For players who prioritize frame rate, High settings at 1080p offer a strong balance, with nearly 118 FPS and only a modest visual downgrade from Ultra.

At 1440p, High settings provide 83.8 FPS, which is comfortably playable. Ultra drops to 52.1 FPS, which may be acceptable for a horror game where slower pacing is common, but the 31.7 FPS difference between High and Ultra is steep. Medium settings at 100.8 FPS are the best choice for those who want a smooth experience with some visual fidelity. Low settings at 127 FPS are only recommended for competitive play, which is unlikely in a horror title.

At 4K, the options are more constrained. Medium settings average 65 FPS, which is playable, while High drops to 49.6 FPS and Ultra to 31.7 FPS. Low settings at 77.1 FPS are the smoothest option but sacrifice most visual quality. For a horror game, atmosphere matters, so Medium settings at 4K strike the best balance between visual immersion and playability. High settings at 4K are borderline, and Ultra is not recommended unless the player accepts a sub-35 FPS experience.

Across all resolutions, the data suggests that Medium or High settings provide the best experience per the measured rows. Low settings waste the GPU's potential, while Ultra settings push frame rates below comfortable thresholds at 1440p and 4K. At 1080p, Ultra is viable, but for consistent performance, High is the sweet spot. The combo's rank of 1402 out of 1741 indicates that it is not a top-tier pairing, but the measured FPS shows it can handle Downfall well at 1080p and 1440p with appropriate settings.
