Downfall

The Intel Core i5-10400F and AMD Radeon RX 6650 XT pairing ranks 1123rd out of 1741 tested combos in Downfall, placing it in the lower-middle tier of the database. This position reflects a balanced but not exceptional system, where neither component is a standout performer in this specific horror title. The combo sits well below the top quartile, suggesting that while it handles the game at standard settings, it will not dominate at maximum graphical fidelity, especially at higher resolutions.

How This Combo Ranks

The combo's rank of 1123 out of 1741 puts it in the 35th percentile of all tested configurations for Downfall, a modest standing that indicates this system is more about consistency than raw speed. The CPU's percentileVsAllCpus of 73 shows it is a solid mid-range processor, while the GPU's percentileVsAllGpus of 72 is nearly identical, creating a well-matched pair that avoids major bottlenecks. In practical terms, this means the system will deliver playable frame rates across most settings, but it will not compete with high-end rigs in the database that achieve top-tier performance. The data suggests this is a dependable 1080p-oriented setup, with the ability to stretch into 1440p if settings are adjusted, but 4K Ultra is clearly out of reach. The rank is heavily influenced by the GPU's limitations at higher resolutions, as the CPU has enough headroom to keep up with the graphics card in most scenarios.

GPU Role

The Radeon RX 6650 XT is the primary driver of Downfall's performance, equipped with 8 GB of GDDR6 memory on a 128-bit bus, providing 280.3 GB/s of bandwidth. Its base clock of 2055 MHz boosts to 2635 MHz, with a game clock of 2410 MHz, and the memory runs at 2190 MHz effective 17.5 Gbps. These specifications give the card a solid foundation for a 2016 horror game, but the 8 GB VRAM capacity becomes a constraint at 4K with higher settings. The GPU's benchmark results show a passmark_g3d score of 17166, placing it in the 72nd percentile overall, with nearest rivals including the AMD Radeon RX 6800M at a 0% delta and the Intel Arc A370M at -0.5% delta. This indicates the card performs almost identically to a mobile flagship, making it a capable desktop option. In Downfall, the GPU's role is most evident in the frame rate scaling from Low to Ultra settings, where the 8 GB buffer and 2048 shading units determine how much detail can be pushed before performance collapses.

Resolution Scaling

The measured FPS data shows a clear pattern of GPU-bound scaling as resolution increases, with the frame rate dropping significantly from 1080p to 4K. At 1080p High, the combo delivers 131.7 FPS, which drops to 97.1 FPS at 1440p High, a 26% reduction, and then to 61.7 FPS at 4K High, another 36% drop. This steep decline at 4K indicates the RX 6650 XT is the limiting factor, as the CPU has sufficient headroom to handle the increased pixel workload. Looking at Low settings, the system hits 196.4 FPS at 1080p, 139.7 FPS at 1440p, and 88.9 FPS at 4K, showing that even at the lowest settings, the GPU cannot maintain high frame rates at 4K due to memory bandwidth constraints. The gap between 1440p and 4K is larger than the gap between 1080p and 1440p, which points to the VRAM and bus width being the bottleneck at higher resolutions. For a horror game, this means players will need to prioritize either resolution or detail, as the system cannot reliably sustain 4K at playable settings beyond Low.

Settings Recommendations

The optimal balance between visual quality and performance comes at Medium settings, which delivers 162.2 FPS at 1080p, 113.7 FPS at 1440p, and 73.6 FPS at 4K. This preset provides a significant boost over High settings, which drop to 131.7 FPS at 1080p and 97.1 FPS at 1440p, while still maintaining a playable 61.7 FPS at 4K. Ultra settings are the worst choice for this combo, as they push the GPU to its limits, resulting in 85.9 FPS at 1080p, 59.4 FPS at 1440p, and a barely playable 36.7 FPS at 4K. For a horror game where atmosphere matters, Medium offers the best trade-off, allowing for smooth motion and consistent frame pacing without sacrificing too much visual fidelity. The data shows that Low settings, while delivering the highest frame rates, are unnecessary for 1080p and 1440p play, as Medium already exceeds 100 FPS at those resolutions. At 4K, Medium is the only realistic option for a consistent experience, as High dips to 61.7 FPS and Ultra falls below 40 FPS.

Measured FPS Breakdown

At 1920x1080, the system delivers its best performance, with Low at 196.4 FPS, Medium at 162.2 FPS, High at 131.7 FPS, and Ultra at 85.9 FPS. These numbers show a clear gradient, with each settings tier costing roughly 20-25% performance, and the jump from High to Ultra being the most punishing at 35% loss. Moving to 2560x1440, the frame rates drop to 139.7 FPS on Low, 113.7 FPS on Medium, 97.1 FPS on High, and 59.4 FPS on Ultra. The 1440p results maintain a smoother scaling curve, with Medium still comfortably above 100 FPS and High just under, but Ultra falls below 60 FPS, making it marginal for a horror game that benefits from consistent frame times. At 3840x2160, the performance takes a significant hit, with Low at 88.9 FPS, Medium at 73.6 FPS, High at 61.7 FPS, and Ultra at 36.7 FPS. The 4K numbers reveal that the GPU is the primary constraint, as even Low settings cannot reach 90 FPS, and Ultra is essentially unplayable. The data indicates that 1080p Medium or High is the sweet spot, 1440p Medium is viable, and 4K should only be attempted on Medium or Low.

CPU Role

The Intel Core i5-10400F provides six cores and twelve threads with a base clock of 2.90 GHz and a boost clock of 4.30 GHz, built on the Comet Lake architecture with a 14 nm process. Its 12 MB of shared L3 cache and dual-channel DDR4 memory support with 42.7 GB/s bandwidth give it enough muscle to avoid bottlenecking the RX 6650 XT in Downfall. The CPU's benchmark results include a cinebench_r23_multicore score of 10297 and a single-core score of 1453, placing it in the 73rd percentile of all CPUs. Its nearest rivals include the AMD EPYC 7552 with a 0.4% delta and the Intel Core i5-8500 with a -1.1% delta, showing it performs on par with older server and desktop chips. In a game like Downfall, which is not heavily multithreaded, the single-core performance of 688 in 3dmark_single_thread is more relevant, and it holds up well enough to keep frame rates stable. The CPU's passmark_multithread score of 12115 indicates it has ample processing power for background tasks, but the game's performance is largely dictated by the GPU, as evidenced by the consistent frame rate scaling across resolutions. The 65 W TDP and PCIe Gen 3 interface are adequate for this workload, with the CPU rarely becoming the limiting factor in any of the measured settings.
