Downfall

The Core i5-13400F paired with the RTX 4080 SUPER delivers a performance curve that clearly maps the balance between CPU and GPU load in Downfall. At 1080p, the combination is heavily front-end bound, producing frame rates that stretch far beyond what most displays can show. The Low preset hits an average of 398.2 FPS, which drops to 324.9 FPS on Medium, 266.1 FPS on High, and 168.6 FPS on Ultra. The scaling from Low to Ultra at this resolution is a 57.6% reduction in average frame rate, indicating that the CPU is feeding frames faster than the GPU can render them even at the highest settings.

Moving to 2560x1440 introduces more GPU pressure, but the pattern remains similar. The Low preset still manages a massive 284.4 FPS, while Medium produces 231 FPS, High delivers 190.7 FPS, and Ultra settles at 118.5 FPS. The drop from Low to Ultra here is 58.3%, nearly identical to the 1080p scaling. This consistency suggests that the RTX 4080 SUPER has enough headroom to handle the increased pixel count without becoming the primary bottleneck until the Ultra preset at this resolution.

At 3840x2160, the GPU finally takes over as the limiting component. The Low preset drops to 178.9 FPS, Medium to 144.7 FPS, High to 118.4 FPS, and Ultra to 76.8 FPS. The Ultra preset at 4K is the only configuration that falls below the 100 FPS threshold, indicating a scenario where the Ada Lovelace architecture is fully saturated. The scaling from 1080p Low to 4K Low shows a 55.1% reduction, while the same comparison for Ultra shows a 54.4% reduction, meaning the GPU load is consistent across settings but the CPU becomes more relevant as resolution decreases.

How This Combo Ranks

The data places this configuration at rank 100 out of 1741 tested combos in Downfall. This percentile positioning is exceptional, placing it in the top 5.7% of all CPU-GPU pairings tested for this title. The rank reflects the synergy between the Core i5-13400F’s 10 cores and 16 threads with the RTX 4080 SUPER’s 10240 shading units and 16 GB of GDDR6X memory.

The CPU’s average benchmark score of 25236 puts it at the 82nd percentile among all processors, with its nearest rival being the AMD Ryzen 5 5600X3D, which scores 25365, a mere 0.5% advantage. The Intel Core i7-13620H scores 25201, just 0.1% behind, showing the 13400F sits in a tightly contested performance band. On the GPU side, the RTX 4080 SUPER averages 53610 across all benchmarks, ranking in the 88th percentile. Its closest competitor, the AMD Radeon RX 6900 XT, scores 53489, a 0.2% difference, while the NVIDIA GeForce RTX 5070 Ti trails by 2.9% with a score of 52086.

In Downfall specifically, the measured FPS data shows that at 1440p Ultra, the combo produces 118.5 FPS, which aligns with the 4K High result of 118.4 FPS, suggesting that the GPU reaches a similar performance ceiling under these loads. The 1080p Low result of 398.2 FPS demonstrates that the CPU can sustain very high frame delivery, but the rank of 100 out of 1741 indicates that there are still 99 configurations that achieve higher average performance in this game, likely due to more powerful CPUs or GPUs that can push the 4K Ultra preset higher than 76.8 FPS.

FAQ

Q: What is the highest average FPS this combo achieves in Downfall?

A: The highest measured average is 398.2 FPS at 1920x1080 with the Low preset, which shows the CPU’s ability to deliver extremely high frame rates when the GPU is not heavily loaded.

Q: How does the combo perform at 4K Ultra settings?

A: At 3840x2160 with the Ultra preset, the average FPS drops to 76.8, which is the lowest measurement across all tested configurations, indicating that the GPU is the limiting factor.

Q: Is there a significant difference between 1440p High and 4K High?

Q: Does the combo maintain playable frame rates at all settings?

A: Yes, even the lowest measured average of 76.8 FPS at 4K Ultra remains above the 60 FPS threshold, while all other configurations exceed 100 FPS, indicating strong performance across the board.

Settings Recommendations

The measured data suggests that the optimal experience depends heavily on the target resolution. For 1080p displays, the Low preset at 398.2 FPS is overkill for most monitors, but the Medium preset at 324.9 FPS offers a better balance of visual quality and performance. The High preset at 266.1 FPS still provides excellent smoothness, while Ultra at 168.6 FPS remains highly playable and offers the best visual fidelity at this resolution.

At 1440p, the High preset delivers 190.7 FPS, which is well above the refresh rate of most high-end monitors. The Ultra preset at 118.5 FPS is the recommended choice for users with 144Hz displays, as it provides a significant visual upgrade over High while maintaining frame rates that exceed the refresh rate. The Medium preset at 231 FPS is only recommended for competitive play where maximum frame rates are prioritized over visual quality.

For 4K displays, the High preset at 118.4 FPS is the sweet spot, offering near-Ultra visuals with frame rates that are comfortable for most gaming scenarios. The Ultra preset at 76.8 FPS is still playable but may not be ideal for fast-paced sections of the game. The Low preset at 178.9 FPS and Medium at 144.7 FPS are viable alternatives for users who prioritize smoothness over fidelity, but they sacrifice significant visual quality. The data indicates that the High preset at 1440p provides the best overall experience, combining high frame rates with good visual detail.

Measured FPS Breakdown

At 1920x1080, the performance range spans from 398.2 FPS on Low to 168.6 FPS on Ultra. The Medium preset achieves 324.9 FPS, while High reaches 266.1 FPS. The scaling between successive presets shows a 18.4% drop from Low to Medium, an 18.1% drop from Medium to High, and a 36.6% drop from High to Ultra. This pattern indicates that the Ultra preset introduces a significant increase in GPU load compared to High.

At 2560x1440, the measurements show 284.4 FPS on Low, 231 FPS on Medium, 190.7 FPS on High, and 118.5 FPS on Ultra. The reduction from Low to Medium is 18.8%, from Medium to High is 17.4%, and from High to Ultra is 37.9%. The High to Ultra drop is the largest at this resolution, reflecting the heavy shader and texture demands of the Ultra preset.

At 3840x2160, the Low preset produces 178.9 FPS, Medium reaches 144.7 FPS, High achieves 118.4 FPS, and Ultra drops to 76.8 FPS. The scaling from Low to Medium is 19.1%, from Medium to High is 18.2%, and from High to Ultra is 35.1%. The absolute frame rates at 4K show that the RTX 4080 SUPER maintains high performance even at the most demanding settings, but the Ultra preset at this resolution is the only configuration that falls below the 100 FPS mark, confirming that the GPU is fully utilized at this point.
