Downfall

Resolution Scaling

The measured frame rates for Downfall show a steep and consistent performance curve as resolution climbs, but the shape of that curve reveals where the bottleneck shifts. At 1920x1080 with High settings, the combo delivers 190.5 FPS. Moving to 2560x1440 drops that to 133.7 FPS, a reduction of roughly 30%. At 3840x2160, the average falls to 83.9 FPS, which is another 37% decline from the 1440p result. The progression is not linear, and that non-linearity is the key takeaway.

At 1080p, the frame rates are exceptionally high across all quality presets. Low settings produce 280.9 FPS, Medium hits 227.1 FPS, and even Ultra maintains 117.5 FPS. These numbers suggest the CPU is doing heavy lifting at this resolution, because the GPU has ample headroom to render frames well beyond typical display refresh rates. The gap between Low and Ultra at 1080p is 163.4 FPS, which indicates that graphical settings have a massive impact when pixel count is low.

As resolution increases to 1440p, the spread between presets narrows somewhat. Low delivers 198.7 FPS, Medium 164.1 FPS, High 133.7 FPS, and Ultra 84.8 FPS. The delta between Low and Ultra is now 113.9 FPS, still substantial but tighter than at 1080p. This compression suggests the GPU is beginning to take on more responsibility, though the CPU remains capable of feeding it.

At 4K, the preset scaling becomes more pronounced in relative terms. Low settings yield 122 FPS, Medium 101 FPS, High 83.9 FPS, and Ultra drops to 51.9 FPS. The gap between Low and Ultra is 70.1 FPS. The Ultra preset at 4K is the only configuration that falls below 60 FPS, which is notable for a horror title where smooth motion matters for atmosphere. The data indicates that 4K Ultra is the point where the Radeon RX 7800 XT becomes the clear limiting factor, as the frame rate collapses to roughly half of what Low settings achieve at the same resolution.

GPU Role

The AMD Radeon RX 7800 XT is built on the RDNA 3.0 architecture with the Navi 32 chip, fabricated on a 5 nm process at TSMC. It carries 16 GB of GDDR6 memory on a 256-bit bus, yielding 624.1 GB/s of bandwidth. The GPU's boost clock is rated at 2430 MHz, with a game clock of 2124 MHz and a base clock of 1295 MHz. These specifications position it as a high-end card, and the benchmark data confirms that positioning within Downfall.

The GPU's memory configuration is particularly relevant for this game. With 16 GB of VRAM, the card has ample capacity for 4K textures and high-detail assets. The 624.1 GB/s bandwidth ensures that texture streaming and memory-intensive effects do not become bottlenecks at higher resolutions. This explains why the card maintains playable frame rates at 4K High (83.9 FPS) and even 4K Medium (101 FPS), where memory pressure would typically be severe.

The compute resources are substantial: 3840 shading units, 240 texture mapping units, 96 render output units, and 60 ray accelerators. The pixel rate is 233.3 GPixel/s and texture rate is 583.2 GTexel/s. Floating-point performance is rated at 37.32 TFLOPS for FP32, with FP16 reaching 74.65 TFLOPS at a 2:1 ratio. These figures translate directly to the high frame rates observed at 1080p and 1440p, where the GPU is never the limiting factor.

The card's overall benchmark percentile is 76, meaning it outperforms roughly three-quarters of all GPUs in the database. Its average benchmark score is 32619, which places it within 0.4% of the AMD FirePro S9300 X2 (32540) and 0.7% ahead of the AMD FirePro S10000 (32388). The nearest rival on the other side is the NVIDIA P104-100 at 32747, a 0.4% gap, and the NVIDIA T600 Mobile at 32849, a 0.7% gap. These margins are tight, indicating the RX 7800 XT sits in a crowded performance tier.

How This Combo Ranks

The combination of the Intel Core i5-10400F and the AMD Radeon RX 7800 XT ranks 648th out of 1741 tested combos in Downfall. That places it in the upper third of all configurations in the database, which is a strong showing for this pairing. The rank reflects the balance between the CPU's capability and the GPU's raw throughput.

The CPU itself holds the 73rd percentile among all processors, with an average benchmark score of 14168. Its nearest rivals include the AMD EPYC 7552 at 14115 (0.4% slower), the AMD Ryzen 3 7320C at 14277 (0.8% faster), and the Intel Core i5-8500 at 14332 (1.1% faster). These margins are all within a couple of percent, meaning the i5-10400F is competitively positioned in synthetic workloads. However, the combo rank in Downfall is what matters for gaming, and 648th out of 1741 is respectable given the CPU's age.

The GPU's percentile of 76 and average score of 32619 are notably higher than the CPU's corresponding metrics. This asymmetry suggests the GPU is the stronger component in this pairing, which is consistent with the resolution scaling data showing GPU-bound behavior at 4K. At lower resolutions, the CPU's six cores and twelve threads are sufficient to keep frame rates high, but the ceiling is set by the GPU's capability.

In practical terms, this combo ranks ahead of many newer configurations because the RX 7800 XT is a dominant graphics card and the i5-10400F provides enough single-thread performance to avoid severe bottlenecks in most scenarios. The rank of 648 out of 1741 means roughly 63% of tested combos are slower, which is a solid position for a mid-range CPU paired with a high-end GPU.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor from the Core 10th Gen series, built on the Comet Lake architecture using a 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.30 GHz. The cache hierarchy includes 64 KB of L1 per core, 256 KB of L2 per core, and 12 MB of shared L3 cache. Memory support is DDR4 in a dual-channel configuration, yielding 42.7 GB/s of bandwidth. The CPU's TDP is 65 W, and it uses the Intel Socket 1200 interface with PCIe Gen 3 (16 lanes from the CPU).

In synthetic benchmarks, the i5-10400F shows a clear multi-threaded advantage. Cinebench R23 multicore scores 10297, while single-core scores 1453. Geekbench multicore reaches 5783 versus 1454 single-core. PassMark multithread is 12115, with single-thread at 2541. The 3DMark results show a scaling pattern: 2-thread score is 1350, 4-thread is 2560, 8-thread is 3929, and 16-thread is 4748. The difference between 8-thread and 16-thread scores is 819 points, indicating diminishing returns beyond 8 threads, which is typical for a 6-core/12-thread part.

In Downfall, the CPU's role is most apparent at 1080p. The frame rates at that resolution are so high that the GPU cannot be the sole determinant. The 280.9 FPS Low result and 227.1 FPS Medium result suggest the CPU is feeding the GPU efficiently, with the processor's boost clock of 4.30 GHz providing strong single-thread performance for game logic and draw calls. The 65 W TDP means thermal headroom is modest, but the benchmark results show no signs of throttling in this title.

The CPU's 73rd percentile ranking places it above most processors in the database, and its average score of 14168 is competitive with the AMD EPYC 7552 (14115) and within 1.2% of the AMD Ryzen Embedded V2546 (14336). For a 2020 release, this processor remains relevant in gaming workloads, particularly when paired with a high-end GPU like the RX 7800 XT. The data shows that at 1440p and 4K, the CPU has sufficient headroom to avoid becoming the primary bottleneck, as the GPU-bound behavior at those resolutions confirms.
