Downfall

How This Combo Ranks

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 5090 D sits at rank 325 out of 3716 tested combos in the database for Downfall. That places this configuration in the top 8.7% of all recorded system pairings, which is a strong showing for a game that is primarily GPU-bound at higher settings. The CPU itself holds a 68th percentile ranking among all tested processors, while the GPU ranks in the 92nd percentile among all tested graphics cards. The gap between those two percentile figures is significant: the RTX 5090 D is operating at a much higher tier than the i5-10400F, and in this game, that imbalance still produces excellent frame rates because Downfall does not heavily tax the processor.

Looking at the CPU's nearest rivals in the database, the i5-10400F posts an average benchmark score of 14185. That is within 0.2% of the Intel Xeon 6756E (14163), within 0.3% of the Intel Core 7 160UL (14232), within 0.5% of the AMD EPYC 7552 (14115), and within 0.6% of the AMD Ryzen 3 7320C (14277). These are all very close scores, meaning the i5-10400F is squarely in a performance band where no single rival holds a meaningful edge. For gaming, this translates to consistent frame pacing, as the CPU is not the limiting factor in Downfall.

The GPU's nearest rivals tell a similar story at a higher performance level. The RTX 5090 D averages 77712 across all GPU benchmarks. The AMD Radeon RX 6650M XT scores 76904, which is 1.1% lower. The AMD Radeon RX 6850M XT scores 78940, which is 1.6% higher. The NVIDIA Tesla P100 PCIe 12 GB scores 79396 (2.1% higher), and the NVIDIA Tesla P100 PCIe 16 GB scores 79605 (2.4% higher). The RTX 5090 D is effectively trading blows with these cards in synthetic tests, although the gaming measurements in Downfall show it performing far above anything those rivals would manage in a modern horror title, thanks to its architecture and memory subsystem.

The combined rank of 325 out of 3716 is driven almost entirely by the GPU. If the CPU were swapped for a faster model, the rank would likely improve slightly, but the data shows that the i5-10400F is already providing enough throughput to let the RTX 5090 D stretch its legs.

CPU and GPU Roles

In Downfall, the division of labor between the Intel Core i5-10400F and the NVIDIA GeForce RTX 5090 D shifts depending on resolution and preset. The database records measured FPS across three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings (Low, Medium, High, Ultra). The scaling between these points reveals where the bottleneck lies.

At 1920x1080, the CPU has more influence than at higher resolutions, but even here the RTX 5090 D is so fast that the i5-10400F never becomes a hard limit. Moving from Low to Ultra at 1080p drops the average from 284 FPS to 202 FPS, a reduction of 82 FPS. That is a 29% penalty for maximum visual quality. The CPU's single-thread score of 688 in 3DMark and its Cinebench R23 single-core score of 1451 are modest by modern standards, but Downfall's engine does not require extreme single-thread performance. The 1080p Ultra result of 202 FPS shows the CPU can feed the GPU well enough to stay far above the 60 FPS playable threshold.

At 2560x1440, the GPU begins to take on more responsibility. The average FPS at Low is 254, at Medium it is 236, at High it is 220, and at Ultra it is 144. The step from High to Ultra is the largest single drop (76 FPS), which is consistent with a GPU that is now working harder on pixel shading and memory bandwidth. The RTX 5090 D has 32 GB of GDDR7 memory on a 512-bit bus with 1.79 TB/s of bandwidth, so it is well equipped for 1440p. The CPU still has headroom, as evidenced by the fact that even the lowest 1440p result (144 FPS at Ultra) is more than double the playable threshold.

At 3840x2160, the GPU is the dominant factor. The average FPS at Low is 214, at Medium it is 175, at High it is 144, and at Ultra it drops to 90. The spread from Low to Ultra is 124 FPS, which is the largest absolute range of any resolution. This is a clear sign that the RTX 5090 D is doing the heavy lifting. The CPU's role at 4K is mostly to keep up with draw calls and physics, and the i5-10400F manages that without dragging the average below 90 FPS even at Ultra. The CPU's multi-threaded scores, such as 10283 in Cinebench R23 and 12115 in Passmark multithread, are sufficient for this workload.

The preset scaling also tells a story. At every resolution, the drop from High to Ultra is proportionally larger than the drop from Medium to High. For example, at 4K, High averages 144 FPS while Ultra averages 90 FPS, a 37.5% reduction. At 1440p, High averages 220 FPS while Ultra averages 144 FPS, a 34.5% reduction. At 1080p, High averages 246 FPS while Ultra averages 202 FPS, an 18% reduction. This suggests that the Ultra preset introduces effects that are particularly demanding on the GPU's shading units and ray tracing cores, and the i5-10400F is not the cause of those frame rate dips.

Measured FPS Breakdown

The database provides exact measured FPS values for this combo, with average, minimum, and maximum figures recorded where available. The minimum and maximum values are only listed for the Medium preset at each resolution, so those are the primary indicators of frame pacing consistency.

At 1920x1080, the Low preset delivers an average of 284 FPS. The Medium preset averages 264 FPS, with a minimum of 225 FPS and a maximum of 304 FPS. The High preset averages 246 FPS. The Ultra preset averages 202 FPS. The gap between the minimum and maximum at Medium is 79 FPS, which shows some variance but remains well above the 60 FPS floor. Even the lowest recorded frame at 1080p Medium (225 FPS) is nearly four times the playable threshold.

At 2560x1440, the Low preset averages 254 FPS. The Medium preset averages 236 FPS, with a minimum of 201 FPS and a maximum of 272 FPS. The High preset averages 220 FPS. The Ultra preset averages 144 FPS. The minimum at Medium (201 FPS) is still more than three times the playable threshold. The variance from minimum to maximum is 71 FPS, which is slightly tighter than at 1080p, indicating that the GPU is smoothing out frame delivery as resolution increases.

At 3840x2160, the Low preset averages 214 FPS. The Medium preset averages 175 FPS, with a minimum of 149 FPS and a maximum of 202 FPS. The High preset averages 144 FPS. The Ultra preset averages 90 FPS. The minimum at Medium (149 FPS) is still 2.5 times the playable threshold. The variance from minimum to maximum is 53 FPS, the smallest of any resolution, which means the GPU is delivering more consistent frames at 4K despite the heavier load.

The absence of minimum and maximum values for Low, High, and Ultra presets means the database only guarantees average performance for those settings. However, the Medium preset data at each resolution provides a useful proxy for frame stability. At 4K Medium, the minimum of 149 FPS is far above 60 FPS, so there is no risk of stutter or dips below playable levels. At 1440p and 1080p, the minimums are even higher. The RTX 5090 D's 32 GB memory buffer and 1.79 TB/s bandwidth are likely contributors to this stability, as the game can keep assets resident without frequent texture streaming.

The Verdict

The Intel Core i5-10400F and NVIDIA GeForce RTX 5090 D combination can run Downfall at every resolution and preset recorded in the database, and it clears the 60 FPS playable threshold with substantial margin in all cases.

At 3840x2160, all four presets (Low, Medium, High, Ultra) are playable. The best settings are Ultra, which averages 90 FPS. That is 30 FPS above the playable threshold, so even the most demanding preset at 4K is comfortable. The Medium preset at 4K averages 175 FPS with a minimum of 149 FPS, so there is no risk of dropping below 60 FPS during intense scenes.

At 2560x1440, all four presets are playable. The best settings are Ultra, which averages 144 FPS. That is more than double the playable threshold. The Medium preset at 1440p averages 236 FPS with a minimum of 201 FPS, meaning even the worst-case frame is over 3 times the threshold.

At 1920x1080, all four presets are playable. The best settings are Ultra, which averages 202 FPS. That is more than triple the playable threshold. The Medium preset at 1080p averages 264 FPS with a minimum of 225 FPS, so the lowest recorded frame is still nearly 4 times the threshold.

The verdict is unambiguous: this combo is overqualified for Downfall at every setting. The weakest recorded result, 4K Ultra at 90 FPS average, is still 50% above the playable threshold. The i5-10400F does not bottleneck the RTX 5090 D in this game, and the GPU has so much headroom that the user can max out every visual option without concern.
