Downfall

# Downfall with AMD Ryzen 7 9800X3D + AMD Radeon RX 6750 XT

The AMD Ryzen 7 9800X3D paired with the AMD Radeon RX 6750 XT lands at rank 833 out of 1,741 tested combinations in Downfall, placing it firmly in the middle of the pack. This is a horror title from 2016 that responds well to raw GPU throughput, and the data shows this combo delivers playable frame rates across most settings, though Ultra presets expose the GPU's limitations at higher resolutions. The CPU, a Zen 5 Granite Ridge part with 8 cores and 16 threads, is clearly not the bottleneck here — its benchmark percentile of 90 versus all CPUs, combined with the GPU's 79th percentile standing, suggests the graphics card carries the performance burden in this pairing.

How This Combo Ranks

At position 833 of 1,741 measured combinations, this setup sits just below the median of all tested hardware pairings in Downfall. The Ryzen 7 9800X3D is a top-tier processor — its average benchmark score of 37,780 places it within 0.1% of the Intel Xeon 6353P (37,811) and Intel Core Ultra 5 225 (37,831), and only 0.6-0.7% behind the Intel Core i9-13900HK and Core i5-13600KF. That CPU strength, however, is partially wasted in this game at lower resolutions where the RX 6750 XT becomes the limiting factor.

The GPU's average benchmark score of 35,327 puts it just 0.2% ahead of the AMD Radeon RX 5600M (35,264), and 0.3% behind the NVIDIA GeForce RTX 5070 Ti Mobile (35,435). The delta to the AMD Radeon 880M (35,646) is only 0.9%, and the GeForce RTX 3080 (35,787) leads by 1.3%. These narrow margins indicate the RX 6750 XT is competitively positioned among its peers, but it lacks the headroom to push this CPU-GPU combo into the upper quartile of Downfall results.

The rank itself reflects a balanced but not exceptional configuration. With 1,741 total combos tested, being at 833 means roughly half of tested systems outperform this pairing. The data suggests that users seeking higher rankings would need substantially more GPU horsepower, as the CPU side is already performing near the top of its class.

GPU Role

The Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, fabricated on a 7 nm process at TSMC. It carries 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. Memory clocks run at 2250 MHz, which translates to 18 Gbps effective, while the GPU's base clock is 2150 MHz and boost clock reaches 2600 MHz. The game clock sits at 2495 MHz, and these clock speeds directly influence how the card handles Downfall's rendering demands.

With 2,560 shading units, 160 texture mapping units, and 64 render output units, the card produces 166.4 GPixel/s pixel rate and 416.0 GTexel/s texture rate. Floating point performance is rated at 13.31 TFLOPS for FP32 and 26.62 TFLOPS for FP16. The 40 ray tracing cores are present, though Downfall's 2016 release predates widespread RT adoption, so their impact on this title is minimal.

The GPU's 12 GB VRAM capacity proves adequate across all tested settings in this game. At 4K Ultra, where the card delivers 42.7 FPS, memory pressure is manageable, and the 432.0 GB/s bandwidth supports the texture streaming typical of horror environments. The 250 W TDP and dual-slot design indicate a power-hungry part, but the benchmark results show consistent performance without thermal throttling artifacts in the measured data.

Settings Recommendations

The measured FPS data indicates that Medium settings offer the best balance of visual quality and performance across all three resolutions. At 1080p Medium, the combo achieves 194.4 FPS, which is 78.6% higher than High settings at the same resolution and nearly double the Ultra result. At 1440p Medium, the 142 FPS result remains well above the 60 FPS threshold for smooth gameplay, while 4K Medium still delivers a respectable 86.2 FPS.

High settings present a viable alternative for users prioritizing visual fidelity, with 159 FPS at 1080p, 115.7 FPS at 1440p, and 71.9 FPS at 4K. These numbers indicate High is playable at all resolutions, though 4K High dips closer to the edge of comfort. Ultra settings, however, should be avoided except at 1080p, where 99.6 FPS is achieved. At 1440p Ultra the frame rate drops to 74.4 FPS, and at 4K Ultra it falls to 42.7 FPS, which is below the smoothness threshold for most players.

Low settings provide maximum frame rates — 243 FPS at 1080p, 172.6 FPS at 1440p, and 108.4 FPS at 4K — but these come at the cost of visual quality that undermines the horror atmosphere. The data supports Medium as the recommended preset: it preserves enough graphical detail for the game's tense environments while maintaining frame rates that exceed display refresh rates in most scenarios.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce 243 FPS, Medium reaches 194.4 FPS, High achieves 159 FPS, and Ultra drops to 99.6 FPS. The gap between Low and Ultra is 143.4 FPS, representing a 59% performance penalty for maximum visual quality. This resolution clearly favors the GPU, with even Ultra remaining above 90 FPS.

Moving to 2560x1440, the frame rates scale down predictably. Low settings yield 172.6 FPS, Medium hits 142 FPS, High manages 115.7 FPS, and Ultra falls to 74.4 FPS. The delta between Low and Ultra here is 98.2 FPS, a 56.9% reduction. Notably, the drop from 1080p to 1440p at each setting is roughly 29% for Low, 27% for Medium, 27% for High, and 25% for Ultra — a consistent scaling pattern that indicates the GPU is the primary constraint.

At 3840x2160, the performance picture changes dramatically. Low settings still deliver 108.4 FPS, which is playable, while Medium drops to 86.2 FPS. High falls to 71.9 FPS, and Ultra plummets to 42.7 FPS. The 4K Ultra result is the only sub-60 FPS measurement in the entire dataset, confirming that this resolution and preset combination exceeds the GPU's capabilities. The scaling from 1440p to 4K is steeper: 37% reduction for Low, 39% for Medium, 38% for High, and 43% for Ultra.

Resolution Scaling

The FPS degradation from 1080p to 4K reveals where the bottleneck lies. At Low settings, performance drops from 243 FPS at 1080p to 172.6 FPS at 1440p and 108.4 FPS at 4K — a 55.4% total reduction. Medium settings show a similar trajectory: 194.4 to 142 to 86.2 FPS, a 55.7% decline. High settings fall from 159 to 115.7 to 71.9 FPS, a 54.8% drop. Ultra settings experience the largest relative decline, going from 99.6 to 74.4 to 42.7 FPS, a 57.1% reduction.

These consistent scaling percentages — all hovering around 55-57% from 1080p to 4K — indicate pixel throughput is the limiting factor. The Ryzen 7 9800X3D's single-thread score of 4,800 in Cinebench R23 and multi-thread score of 34,004 provide ample CPU headroom even at 1080p, where the 243 FPS Low result shows the GPU is still the constraining component. If the CPU were the bottleneck, we would expect to see diminishing FPS gaps at higher resolutions as the GPU becomes more stressed; instead, the linear scaling confirms a GPU-bound scenario across all settings.

The 4K Ultra result of 42.7 FPS is particularly telling. This represents a 57.1% reduction from the 1080p Ultra score, and the absolute value falls below the 60 FPS threshold. The data indicates that users targeting 4K should stick to Medium settings at most, where 86.2 FPS provides a comfortable margin. The RX 6750 XT's 12 GB VRAM and 432.0 GB/s bandwidth are sufficient for the game's demands, but the 13.31 TFLOPS FP32 throughput simply cannot sustain Ultra settings at 4K resolution in this title.
