Downfall

The AMD Ryzen 5 5600X paired with the NVIDIA GeForce RTX 5090 presents a stark contrast in hardware generations. The CPU, a Zen 3 (Vermeer) part from the 5000 series, launched on November 4, 2020, with a launch MSRP of $299. It brings 6 cores and 12 threads to the AM4 platform, with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. This is a 7 nm design with 32 MB of L3 cache and a 65 W TDP, making it a highly efficient desktop processor. In contrast, the RTX 5090 is a Blackwell 2.0 flagship, released on January 29, 2025, built on a 5 nm process with a 575 W TDP. This pairing is a test of how a modern top-tier GPU performs when driven by a previous-generation mid-range CPU.

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

The Ryzen 5 5600X’s specifications establish it as a strong but not extreme multi-threaded performer. Its 6-core/12-thread configuration, combined with a 4.60 GHz boost clock, allows it to handle the demands of a 2016 horror title like Downfall without becoming a bottleneck at lower resolutions. Benchmark data for the CPU shows a single-thread score of 917 in 3DMark, a Cinebench R23 single-core score of 2622, and a multi-core score of 18578. These results place the CPU in the 78th percentile of all CPUs, indicating it remains a capable processor for gaming workloads.

The relationship between the CPU and the GPU in Downfall is evident in the frame rate data. At 1080p, the CPU’s processing power is critical for feeding the GPU with draw calls. The measured 1080p Low average of 377.5 FPS and 1080p High average of 307.7 FPS show that the Ryzen 5 5600X can push exceptionally high frame rates, suggesting that the game’s engine can scale well with this processor's single-core capabilities. The 3DMark 2-thread score of 1793 and 4-thread score of 3363 indicate that the processor has strong low-thread-count performance, which is often what older games rely upon for the main game logic and rendering thread.

However, the CPU’s 6-core limit does show in the data when compared to its synthetic benchmarks. The 3DMark max-thread score of 5588 is only slightly above the 16-thread score of 5582, indicating that the extra threads beyond 6 cores are not providing significant additional throughput. This suggests that in Downfall, which may not be heavily optimized for more than 6 cores, the CPU is providing a stable baseline. The PassMark multi-thread score of 21858 further supports this, showing that while the CPU is not the absolute top-tier for multi-threaded tasks, it is more than sufficient for a game of this era. The data indicates that the 5600X is a balanced partner for the RTX 5090, enabling the GPU to reach its full potential in this specific title.

A: The RTX 5090 features 32 GB of GDDR7 memory on a 512-bit bus, providing a memory bandwidth of 1.79 TB/s. This high bandwidth is a key factor in maintaining strong frame rates at 4K resolution, as the GPU can quickly access the large textures and assets required.

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

The measured FPS data reveals a clear progression of performance scaling across resolutions. At 1080p, the frame rates are exceptionally high, indicating that the CPU is the primary limiting factor, as the GPU has ample headroom to render frames quickly. At 1080p Ultra, the average FPS is 190.5. Moving to 1440p, the same Ultra settings yield an average of 138.7 FPS, a drop of 27.2%. At 4K Ultra, the average FPS falls to 82.4, which is a 40.6% drop from the 1440p result and a 56.7% drop from the 1080p result.

This scaling pattern is characteristic of a system where the GPU becomes the bottleneck as resolution increases. The workload on the GPU grows with the pixel count, while the CPU's workload remains relatively constant. The fact that the 4K Ultra frame rate (82.4 FPS) is still above 60 FPS shows the raw power of the RTX 5090, but the significant drop from 1080p to 4K demonstrates the GPU is now the limiting component. The difference between 1080p Low (377.5 FPS) and 1440p Low (329 FPS) is a modest 12.8% drop, but the transition to 4K Low (201.4 FPS) shows a 38.8% drop from 1440p. This indicates that even at lower settings, the pixel fill rate demand at 4K is substantial, and the GPU's rendering capabilities, rather than the CPU's instruction throughput, dictate the final frame rate. The data clearly shows the role of the CPU is dominant at 1080p, while the RTX 5090's performance defines the experience at 4K.

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

The following data provides a comprehensive view of the average FPS for the AMD Ryzen 5 5600X and NVIDIA GeForce RTX 5090 combination in Downfall.

1920x1080 (Full HD)

• Low: The average FPS is 377.5.
• Medium: The average FPS is 349.7.
• High: The average FPS is 307.7.
• Ultra: The average FPS is 190.5.

At 1080p, the frame rates are consistently above 190 FPS across all settings. The difference between Low and Ultra is 187 FPS, a 49.5% reduction in performance. This shows that while the CPU can drive very high frame rates, the Ultra settings introduce a significant load on the GPU, even at this lower resolution.

2560x1440 (Quad HD)

• Low: The average FPS is 329.
• Medium: The average FPS is 265.6.
• High: The average FPS is 222.2.
• Ultra: The average FPS is 138.7.

At 1440p, the frame rates remain high, with the Low setting producing an average of 329 FPS. The scaling from Low to Ultra shows a 190.3 FPS drop, or 57.8%. The performance difference between 1080p and 1440p at the same settings is noticeable but not dramatic, with a 12.8% drop for Low and a 27.2% drop for Ultra.

3840x2160 (4K Ultra HD)

• Low: The average FPS is 201.4.
• Medium: The average FPS is 167.3.
• High: The average FPS is 137.9.
• Ultra: The average FPS is 82.4.

At 4K, the GPU is heavily stressed. The Low setting still produces over 200 FPS, but the Ultra setting drops to 82.4 FPS. The drop from Low to Ultra is 119 FPS, a 59.1% reduction. The 4K results demonstrate that while the RTX 5090 is powerful, the most demanding settings at this resolution will push the frame rate down significantly, though it remains playable.

How This Combo Ranks — use comboRankInGame vs other tested combos

The AMD Ryzen 5 5600X and NVIDIA GeForce RTX 5090 combination holds a prominent position in the benchmark database for Downfall. With a combo rank of 35 out of 1741 tested configurations, this pairing is in the 98th percentile, meaning it outperforms 98% of all other tested CPU and GPU combinations in this game. This high ranking is primarily driven by the immense performance of the RTX 5090, especially its ability to maintain high frame rates at 1440p and 4K, where the GPU is the primary bottleneck.

While the Ryzen 5 5600X is not the most powerful CPU available, its performance is sufficient to not hinder the RTX 5090 in this specific title. The rank of 35 demonstrates the effectiveness of the pairing. The data indicates that this combo is positioned among the top-tier systems for playing Downfall, offering a very high-performance experience. The CPU's 78th percentile ranking among all CPUs confirms its enduring gaming capability, but it is the GPU's 94th percentile ranking that pushes this combo to the top 35. The deltaPct from the CPU's nearest rivals is minimal, meaning that swapping to a Ryzen 5 5600GT or Intel Core i7-10700 would likely have a negligible impact on the overall frame rate, as the GPU is doing the heavy lifting in most scenarios. This ranking confirms that users with this configuration can expect a top-tier gaming experience in Downfall without any significant performance compromises.
