Downfall

The AMD Ryzen 5 5600 and AMD Radeon RX 6600 pairing delivers a solid, if not spectacular, showing in Downfall, a horror title that clearly scales with both resolution and graphical fidelity. The measured data reveals that this combination is best suited for high-refresh-rate 1080p gaming and remains quite capable at 1440p, while 4K Ultra proves to be a bridge too far for the GPU. The benchmark results indicate a system where the graphics card is the primary limiting factor as resolution climbs, but the processor holds its own at lower settings where frame rates soar.

Resolution Scaling

The frame rate data shows a predictable but pronounced decline as resolution increases, pointing squarely at the GPU as the performance bottleneck in this pairing. At 1080p with High settings, the combo achieves an average of 118.1 FPS. Moving to 1440p High drops that figure by roughly 28% to 84.1 FPS, and at 4K High, the average falls to 51.4 FPS—a 56% reduction from the 1080p baseline. This steep curve is characteristic of a mid-range graphics card like the RX 6600, which has the raw compute to handle lower pixel counts but struggles to maintain high output as the render load expands.

The scaling pattern becomes even more telling when examining the Low settings preset. At 1920x1080 Low, the system produces a very high 175.6 FPS, which indicates that the CPU and GPU are both working efficiently at this light load. Dropping to 2560x1440 Low yields 124.7 FPS, and at 3840x2160 Low, the average is 78.6 FPS. The fact that even at Low settings, 4K performance falls below the 1080p High figure highlights that the RX 6600's 8 GB frame buffer and 128-bit memory interface are being saturated by the sheer pixel count, regardless of the level of detail.

The jump from Medium to Ultra settings at each resolution also reveals the GPU's limits. At 1080p, the gap between Medium (140.5 FPS) and Ultra (74.9 FPS) is a massive 87% performance penalty. At 1440p, the same settings gap sees frame rates drop from 105 FPS to 50.3 FPS, and at 4K, it goes from 64.7 FPS down to 31.4 FPS. This indicates that Downfall's Ultra preset includes effects that heavily tax the rasterization units and memory bandwidth of the RX 6600, making it a setting reserved for lower resolutions or for users who prioritize visual fidelity over smooth motion.

CPU Role

The AMD Ryzen 5 5600 is a six-core, twelve-thread processor based on the Zen 3 architecture, and its specifications suggest it is well-matched to a mid-range GPU in this title. With a base clock of 3.50 GHz and a boost clock of 4.40 GHz, the chip offers strong single-thread performance, which is often critical for game logic and draw call submission. The processor's benchmark scores back this up: it achieves a 3dMark single-thread score of 882 and a Cinebench R23 single-core score of 2584, placing it in the 79th percentile of all CPUs.

In Downfall, the CPU's role appears to be subservient to the GPU at higher resolutions, but it becomes more relevant at 1080p with lower settings. At 1080p Low, the system hits 175.6 FPS, a figure that suggests the Ryzen 5 5600 is capable of feeding frames at a high rate without becoming a bottleneck. The processor's 32 MB of shared L3 cache and dual-channel DDR4 memory support with 51.2 GB/s of bandwidth provide ample data throughput for the game's asset streaming.

Comparing the processor to its nearest rivals, the data shows it is firmly in the middle of the pack. The Ryzen 5 5600 has an average benchmark score of 21765, which is 0.6% ahead of the Intel Xeon D-1746TER and 0.9% ahead of the Intel Core i7-11700F. It trails the AMD EPYC 9554P and EPYC 9534 by 0.6%. These are negligible differences in synthetic workloads, and in a game like Downfall, the 5600's 6-core/12-thread configuration is sufficient to avoid CPU-bound scenarios except perhaps at the very lowest settings where frame rates exceed 170 FPS.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with the Navi 23 chip, and its specifications directly explain the scaling behavior observed in Downfall. The GPU features 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s of bandwidth. Its boost clock is rated at 2491 MHz, with a game clock of 2044 MHz, and it has 1792 shading units. These specs place the card in the 69th percentile of all GPUs, with an average benchmark score of 25235.

The GPU's performance in this horror title is characterized by strong 1080p capabilities and a sharp falloff at 4K. The measured data shows that at 1080p Medium, the card delivers 140.5 FPS, which is excellent for a smooth experience. However, the 4K Ultra result of 31.4 FPS is barely playable, and even 4K High at 51.4 FPS is below the 60 FPS threshold that most users target. This suggests that the RX 6600's 8 GB memory capacity and bandwidth are insufficient for the high-resolution textures and effects that Downfall's Ultra preset demands.

The GPU's rivalry data confirms it is a competitive mid-range part. The RX 6600 has a 0% deltaPct against the AMD Radeon 890M, a -0.2% deltaPct against the AMD Radeon RX 580 2048SP, and a 0.5% deltaPct against the NVIDIA GeForce RTX 3060 Ti. This means its synthetic performance is nearly identical to the RTX 3060 Ti, although the 6600 has a lower TDP of 132 W. In Downfall, the RX 6600's texture rate of 279.0 GTexel/s and pixel rate of 159.4 GPixel/s are the key specs that determine how quickly it can fill the screen, and these metrics limit its ability to maintain high frame rates at 4K.

How This Combo Ranks

In the comprehensive database of tested combinations, this pairing of the Ryzen 5 5600 and RX 6600 ranks 1400th out of 1741 total combos for Downfall. This places it in the lower 20% of all systems tested, which is a somewhat surprising result given the individual component performance. The rank suggests that while the CPU and GPU are each competent on their own, their combination in this game does not yield top-tier results, likely due to the GPU's memory bandwidth constraints at higher resolutions.

This ranking is more a reflection of the competition than a condemnation of the hardware. Many of the 1741 combos include much higher-end GPUs with larger frame buffers and wider memory buses, which naturally perform better in a title that scales heavily with resolution. The combo's position at 1400th indicates that users with this setup should not expect to max out the game at 4K, but they will have a very playable experience at 1080p and 1440p with adjusted settings.

The data also shows that the system is balanced in the sense that neither component severely bottlenecks the other at typical gaming resolutions. At 1080p High, the 118.1 FPS result is a good indication that the CPU can keep up with the GPU's output. The rank is a useful reference point for potential buyers, signaling that this is a mainstream configuration rather than an enthusiast one for Downfall.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the system's capabilities across all resolution and settings combinations. At 1920x1080, the system performs admirably across the board. The Low preset achieves an average of 175.6 FPS, which is exceptionally high and ideal for competitive play or high-refresh-rate monitors. Medium settings deliver 140.5 FPS, High settings produce 118.1 FPS, and Ultra settings still manage a very respectable 74.9 FPS. This resolution is clearly the sweet spot for this hardware, offering smooth gameplay even with maximum visual fidelity.

At 2560x1440, the performance remains strong but shows the first signs of GPU limitation. The Low preset averages 124.7 FPS, which is still highly playable. Medium settings drop to 105 FPS, and High settings produce 84.1 FPS. The Ultra preset, however, falls to 50.3 FPS, which is a significant reduction and may require a lower refresh rate or adaptive sync to feel smooth. This resolution is a good match for the hardware if the user is willing to dial back from Ultra settings.

At 3840x2160, the system is out of its depth for demanding settings. The Low preset averages 78.6 FPS, which is usable, but the Medium preset drops to 64.7 FPS. High settings yield 51.4 FPS, and Ultra settings bring the system to its knees at 31.4 FPS. The data clearly shows that 4K is not a viable option for this combo unless the user sticks to Low or Medium settings and accepts frame rates below 60 FPS. For users targeting 4K, a more powerful GPU with greater memory bandwidth would be required to achieve smooth performance in Downfall.
