Downfall

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 9 5950X is a 16-core, 32-thread desktop processor built on the Zen 3 architecture (Vermeer) using TSMC's 7 nm process. It operates with a base clock of 3.40 GHz and a boost clock of 4.90 GHz, drawing a 105 W TDP. The chip's cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a substantial 64 MB of L3 cache. Memory support is DDR4 over a dual-channel bus, providing 51.2 GB/s of bandwidth, and the CPU connects via PCIe Gen 4 with 20 lanes.

For a game like Downfall, a horror title from 2016, the CPU's raw thread count is far more than the workload demands. Benchmark data shows this processor scores 10,810 in 3DMark with 16 threads and 11,597 with max threads, while single-thread performance sits at 944 in 3DMark and 1,614 in Cinebench R23 single-core. The game's measured FPS results at 1080p Low reach 291 FPS average, suggesting the CPU is not a limiting factor at lower resolutions. The 16-core design ensures that even if Downfall spawns background threads, the headroom is ample.

The 5950X ranks in the 91st percentile among all CPUs, with an average benchmark score of 51,947. Its nearest rivals include the Intel Core Ultra 5 235HX (average score 52,073, delta -0.2%), AMD EPYC 8124P (52,121, delta -0.3%), Intel Core i9-13900F (51,730, delta 0.4%), and Intel Core i7-14700 (52,301, delta -0.7%). The deltas are all within a fraction of a percent, meaning the 5950X is statistically tied with these chips in aggregate performance.

In this specific pairing with the RX 6800 XT, the CPU's role becomes clearer when examining frame rates across settings. At 1080p Low, the combination produces 291 FPS, which is 49% higher than 1080p High (195 FPS). Such a large gap between Low and High at the same resolution points to the GPU becoming more involved as settings increase, but the CPU still delivers enough throughput to keep minimums respectable. The 5950X's 32 threads do not appear to bottleneck even at high frame rates, as the data shows no single-thread constraint manifesting as stutter or frame drops in the measured rows.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear scaling pattern as resolution increases. At High settings, the average frame rate drops from 195 FPS at 1080p to 139 FPS at 1440p, then to 87 FPS at 4K. This represents a 29% reduction from 1080p to 1440p, and a further 37% reduction from 1440p to 4K. The overall drop from 1080p to 4K at High settings is 55%, meaning the 4K result (87 FPS) is less than half of the 1080p result (195 FPS).

Low settings show a similar trend but with higher absolute values: 291 FPS at 1080p, 207 FPS at 1440p, and 129 FPS at 4K. The percentage drop from 1080p to 1440p is 29%, and from 1440p to 4K is 38%, nearly identical to the High settings pattern. This consistency suggests the scaling factor is resolution-driven rather than settings-driven.

Medium settings provide the only rows with min and max FPS values. At 1080p Medium, the average is 238 FPS with a minimum of 202 and maximum of 273. At 1440p Medium, the average drops to 170 FPS with a minimum of 144 and maximum of 195. At 4K Medium, the average is 106 FPS with a minimum of 90 and maximum of 121. The minimum-to-average ratio stays relatively stable: 85% at 1080p, 85% at 1440p, and 85% at 4K, indicating frame pacing remains consistent across resolutions.

Ultra settings show the steepest absolute drop. The 1080p Ultra average of 122 FPS falls to 87 FPS at 1440p (a 29% drop) and then to 54 FPS at 4K (a 38% drop from 1440p). The 4K Ultra result of 54 FPS is the lowest measured value across the entire dataset.

The pattern strongly indicates that the GPU is the primary limiting factor at higher resolutions. The RX 6800 XT's 16 GB of GDDR6 memory and 512.0 GB/s bandwidth are being exercised more heavily as pixel count increases. The CPU's contribution remains relatively constant, as evidenced by the consistent percentage drops between resolutions regardless of settings. If the CPU were the bottleneck, we would expect the scaling to flatten out at higher resolutions, but instead the frame rates continue to fall proportionally with pixel count.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 9 5950X with the AMD Radeon RX 6800 XT ranks 1,160 out of 3,716 tested combos in Downfall. This places the pairing in the top 31% of all configurations tested. Given that the CPU is in the 91st percentile and the GPU is in the 85th percentile, the combo ranking is slightly lower than either component's individual percentile, suggesting that Downfall does not fully leverage the strengths of this particular pairing.

The rank of 1,160 out of 3,716 means there are 2,556 combos that perform better in this game. This is notable because the 5950X and RX 6800 XT are both high-end components from the same generation (launched November 2020 and October 2020 respectively). The game's 2016 release date likely means it was designed for older hardware, and the measured FPS values—reaching 291 FPS at 1080p Low—show the combo is far from struggling. The relatively low rank may reflect that other combos with newer GPUs or CPUs achieve even higher frame rates in this title, particularly at 1080p where CPU overhead is more apparent.

The deltaPct values for the GPU's nearest rivals show the RX 6800 XT is 1.5% ahead of the NVIDIA RTX A1000 Mobile, 2.5% behind the Intel Arc A550M, 3% behind the NVIDIA GeForce RTX 5070 Ti, and 3% behind the AMD Radeon RX Vega 64 in average benchmark scores. These small deltas indicate the GPU is competitive with a range of cards, but none of these rivals appear in the combo ranking data, so direct comparisons in Downfall are not possible from the provided facts.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

1920x1080 (1080p):

• Low: 291 FPS average
• Medium: 238 FPS average, 202 FPS minimum, 273 FPS maximum
• High: 195 FPS average
• Ultra: 122 FPS average

2560x1440 (1440p):

• Low: 207 FPS average
• Medium: 170 FPS average, 144 FPS minimum, 195 FPS maximum
• High: 139 FPS average
• Ultra: 87 FPS average

3840x2160 (4K):

• Low: 129 FPS average
• Medium: 106 FPS average, 90 FPS minimum, 121 FPS maximum
• High: 87 FPS average
• Ultra: 54 FPS average

The data shows a clear hierarchy: at every resolution, Low produces the highest frame rate, followed by Medium, then High, with Ultra producing the lowest. The gap between Low and Ultra is substantial. At 1080p, the difference is 169 FPS (291 vs 122), representing a 58% reduction. At 1440p, the gap narrows to 120 FPS (207 vs 87), a 58% reduction. At 4K, the gap is 75 FPS (129 vs 54), again a 58% reduction. This consistent 58% drop from Low to Ultra across all resolutions reinforces that the settings scaling is uniform regardless of resolution.

The Medium settings rows provide the only minimum and maximum data. At 1080p, the range spans 71 FPS (202 to 273). At 1440p, the range is 51 FPS (144 to 195). At 4K, the range is 31 FPS (90 to 121). The narrowing range at higher resolutions is consistent with GPU-bound behavior, where frame time variance decreases as the render load increases.

Settings Recommendations — which preset gives the best experience per the measured rows

For 1080p displays, the High preset at 195 FPS average provides a smooth experience while maintaining visual fidelity. The Ultra preset at 122 FPS is also playable, but the 37% drop from High to Ultra may not justify the visual gains, especially since the Medium preset at 238 FPS offers a substantial frame rate advantage with only a moderate reduction in quality. For competitive or high-refresh-rate play, Low at 291 FPS is the clear choice, though it sacrifices visual detail.

At 1440p, the High preset at 139 FPS is the sweet spot, offering a balance between image quality and frame rate that exceeds typical 60 Hz or 120 Hz displays. The Medium preset at 170 FPS is better for high-refresh monitors, while Ultra at 87 FPS remains above 60 FPS and is viable for slower-paced horror gameplay where visual atmosphere matters more than raw frame rate. Low at 207 FPS is excessive for most 1440p displays and would only benefit 240 Hz panels.

For 4K, the situation is more constrained. The High preset at 87 FPS is ideal for 60 Hz displays and provides headroom above the refresh rate. The Medium preset at 106 FPS is even better for 120 Hz panels, with a minimum of 90 FPS ensuring no drops below 90 FPS. The Ultra preset at 54 FPS is below 60 FPS and may introduce visible stutter on standard displays, making it less recommended unless the visual quality is paramount. Low at 129 FPS is unnecessary for 4K since the GPU is the bottleneck, and the Low preset's reduced settings do not help overcome the resolution limitation.

Across all resolutions, the Medium preset offers the best balance, with the measured minimums ensuring consistent frame delivery. At 1080p, Medium's 238 FPS average with a 202 FPS minimum guarantees smooth gameplay. At 1440p, Medium's 170 FPS average with a 144 FPS minimum is excellent. At 4K, Medium's 106 FPS average with a 90 FPS minimum is the only preset that keeps minimums comfortably above 60 FPS.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6800 XT is built on the RDNA 2.0 architecture with the Navi 21 chip, manufactured on TSMC's 7 nm process. The GPU features 4,608 shading units, 288 texture mapping units, and 128 raster operation units, along with 72 ray tracing cores. It operates with a base clock of 1825 MHz and a boost clock of 2250 MHz, with a game clock of 2015 MHz. Memory is 16 GB of GDDR6 on a 256-bit bus, providing 512.0 GB/s of bandwidth. The GPU's pixel rate is 288.0 GPixel/s, and its texture rate is 648.0 GTexel/s, with FP32 performance of 20.74 TFLOPS.

The GPU's memory configuration is particularly relevant for Downfall at high resolutions. The 16 GB VRAM capacity ensures that even at 4K Ultra, the game's textures and buffers fit comfortably within memory, avoiding any spillover to system memory. The 512.0 GB/s bandwidth is sufficient for the measured frame rates, as the data shows no signs of memory bandwidth throttling—the frame rate scaling between resolutions is linear and predictable.

The RX 6800 XT ranks in the 85th percentile of all GPUs, with an average benchmark score of 48,477. Its nearest rivals include the NVIDIA RTX A1000 Mobile (1.5% ahead), Intel Arc A550M (2.5% behind), NVIDIA GeForce RTX 5070 Ti (3% behind), and AMD Radeon RX Vega 64 (3% behind). The GPU's benchmark results show a Passmark G3D score of 24,980 and a Passmark GPU compute score of 13,245, indicating strong rasterization and compute capabilities.

The GPU's 300 W TDP and dual-slot design with 2x 8-pin power connectors suggest it draws significant power, but the measured FPS data shows it delivers consistent performance in Downfall. The DirectX 12 Ultimate support (12_2) is relevant since the game can utilize modern rendering features, though the 2016 release date means the game's engine predates many of these features. The GPU's Vulkan 1.4 and OpenGL 4.6 support provide API flexibility, but the game's performance appears primarily limited by rasterization throughput rather than API overhead.

At 4K Ultra, the GPU produces 54 FPS average, which is 38% lower than 1440p Ultra's 87 FPS. This drop aligns with the 2.25x increase in pixel count from 1440p to 4K, but the frame rate does not drop proportionally—it drops by 38% rather than 56%—indicating that the GPU has some headroom in its memory bandwidth and compute units to partially absorb the resolution increase. The 4K Medium result of 106 FPS further confirms that the GPU can handle 4K when settings are moderated, with the minimum of 90 FPS showing stable delivery.
