Downfall

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. Its base clock is 2.90 GHz with a boost clock of 4.30 GHz, and it carries a 65 W TDP. The CPU’s cache layout includes 64 KB of L1 per core, 256 KB of L2 per core, and 12 MB of shared L3 cache. Memory support is DDR4 over a dual-channel bus, yielding a bandwidth of 42.7 GB/s. In synthetic workloads, this CPU scores 10,297 in Cinebench R23 multi-core and 1,453 in single-core, while Geekbench shows 5,783 multi-core and 1,454 single-core. Its Passmark multithread score is 12,115, and its single-thread score is 2,541. The processor sits at the 73rd percentile of all CPUs, with an average benchmark score of 14,168.

For a horror title like Downfall, the CPU’s role is to handle game logic, physics, and frame pacing. The 6-core/12-thread configuration is sufficient for modern threading, and the data indicates that at 1080p Low settings, the combination reaches 237.8 FPS average. This high frame rate suggests the CPU is not a bottleneck at lower resolutions, as the GPU is likely the limiting factor. However, the processor’s nearest rivals in average score include the AMD EPYC 7552 (0.4% higher), the AMD Ryzen 3 7320C (0.8% lower), and the Intel Core i5-8500 (1.1% lower). These deltas are minimal, meaning the i5-10400F performs within a tight band of similar processors, and in Downfall, the CPU’s single-thread strength (1,453 in Cinebench R23) is more relevant than its multi-core throughput, given the game’s age and genre. The boost clock of 4.30 GHz helps maintain responsiveness in scenes with sudden enemy spawns, a common horror mechanic.

GPU Role

The AMD Radeon RX 6750 XT is a RDNA 2.0 architecture GPU built on a 7 nm process by TSMC, featuring 17,200 million transistors on a 335 mm² die. It has a base clock of 2150 MHz, a game clock of 2495 MHz, and a boost clock of 2600 MHz. The memory subsystem consists of 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s of bandwidth with an effective speed of 18 Gbps. The GPU has 2,560 shading units, 160 texture mapping units, and 64 raster operation units, with 40 ray tracing cores. Its pixel rate is 166.4 GPixel/s, texture rate is 416.0 GTexel/s, and FP32 performance is 13.31 TFLOPS. The card’s TDP is 250 W, requiring a 600 W suggested power supply, and it uses a dual-slot design with 1x 6-pin and 1x 8-pin power connectors.

The GPU’s benchmark results place it at the 79th percentile of all GPUs, with a Passmark G3D score of 20,700 and a Geekbench Vulkan score of 109,310. Its nearest rivals include the AMD Radeon RX 5600M (0.2% higher), the NVIDIA GeForce RTX 5070 Ti Mobile (0.3% lower), and the AMD Radeon 880M (0.9% lower). In Downfall, the GPU’s 12 GB VRAM is ample for the game’s textures, and the high memory bandwidth supports smooth rendering at higher resolutions. The boost clock of 2600 MHz ensures that the GPU can push frame rates well above 100 FPS at 1080p, but the data shows that the GPU becomes the primary bottleneck at 4K Ultra, where the average FPS drops to 47. The 64 ROPs and 160 TMUs are sufficient for the game’s geometry and pixel fill requirements, but the GPU’s performance ceiling is evident when settings are maxed out.

Resolution Scaling

The measured FPS data shows a clear progression as resolution increases from 1920x1080 to 3840x2160. At 1080p Low, the average FPS is 237.8, which drops to 173.5 at 1440p Low and 110 at 4K Low. This represents a 27% decrease from 1080p to 1440p and a 36.6% decrease from 1440p to 4K, indicating that the GPU is increasingly stressed as pixel count rises. At High settings, the pattern continues: 163.9 FPS at 1080p, 114.5 at 1440p, and 71.1 at 4K. The drop from 1080p to 1440p is 30.1%, and from 1440p to 4K is 37.9%. At Medium settings, the scores are 193.9, 137.6, and 87.8 FPS, with drops of 29% and 36.2%, respectively. The Ultra settings show the steepest decline: 101.7 FPS at 1080p, 71.7 at 1440p, and 47 at 4K, which is a 29.5% drop followed by a 34.4% drop.

These scaling patterns reveal that the CPU is not the limiting component at lower resolutions. At 1080p Low, the frame rate of 237.8 FPS approaches the CPU’s potential, but as resolution increases, the GPU’s workload grows disproportionately. The fact that 4K Ultra produces only 47 FPS—less than half of the 1080p Ultra score of 101.7—suggests that the GPU is the dominant constraint at higher settings. The diminishing returns from 1440p to 4K (around 34-38% drops) are typical for a GPU-bound scenario, whereas the 27-30% drops from 1080p to 1440p show a more balanced load. This indicates that players targeting 4K will need to reduce settings, while 1080p and 1440p are more forgiving.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings levels. At 1920x1080, the Low setting yields an average of 237.8 FPS, Medium produces 193.9 FPS, High reaches 163.9 FPS, and Ultra drops to 101.7 FPS. These numbers show that the game is highly playable at all settings, with even Ultra maintaining triple-digit frame rates. The gap between Low and Ultra is 136.1 FPS, indicating that the GPU has headroom at 1080p but is still taxed by higher quality presets.

At 2560x1440, the average FPS values are 173.5 for Low, 137.6 for Medium, 114.5 for High, and 71.7 for Ultra. The drop from Low to Ultra is 101.8 FPS, and the scaling is less linear than at 1080p, with Ultra suffering a more pronounced hit. The 1440p Ultra score of 71.7 FPS is still above the 60 FPS threshold, but it is approaching the lower bound of smooth gameplay. At 3840x2160, the numbers are 110 FPS for Low, 87.8 for Medium, 71.1 for High, and 47 for Ultra. The Low setting remains fluid, but Ultra falls below 60 FPS, making it less ideal for competitive or fast-paced horror sequences. The 4K High setting at 71.1 FPS is a viable option, though the 4K Ultra experience would require a more powerful GPU.

How This Combo Ranks

The combination of the Intel Core i5-10400F and AMD Radeon RX 6750 XT ranks 829 out of 1,741 tested combos in Downfall, placing it in the 47.6th percentile of all combinations. This mid-pack ranking reflects a system that is capable but not top-tier, as the CPU and GPU are both mid-range components from their respective generations. The CPU’s 73rd percentile and the GPU’s 79th percentile individually suggest that each part is above average, but the combo’s ranking indicates that other pairings with higher-end components achieve better results. The data implies that the GPU is the stronger component in this pairing, as its percentile is slightly higher than the CPU’s, and the frame rates at 1080p and 1440p are largely GPU-limited. At 4K Ultra, the GPU’s limitations are exposed, but the combo remains competitive for 1080p and 1440p gaming, which is typical for this hardware class.
