Downfall

The AMD Ryzen 9 7900X paired with the AMD Radeon RX 9070 XT delivers a compelling 1080p and 1440p experience in Downfall, but the data shows that 4K Ultra remains a demanding target for this combination. The measured frames per second across the resolution and settings matrix reveal a system that is primarily GPU-bound at higher resolutions, while the 12-core CPU provides ample headroom at lower settings.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 produces a predictable and significant performance drop, but the magnitude varies heavily depending on the selected quality preset. At High settings, the average frame rate falls from 206.9 FPS at 1080p to 150.8 FPS at 1440p, a reduction of 56.1 FPS. Moving to 4K High drops the average to 94.7 FPS, which is a 54.2% decrease from the 1080p result. This scaling pattern indicates that the Radeon RX 9070 XT’s 16 GB frame buffer and 644.6 GB/s of memory bandwidth are being taxed substantially as pixel count increases.

The scaling behavior at Low settings tells a different story about the limiting component. At 1920x1080 Low, the combo produces 309.1 FPS average, which is an exceptionally high ceiling that suggests the CPU is still keeping pace with the GPU. At 2560x1440 Low, the average drops to 224.3 FPS, and at 4K Low it reaches 137.9 FPS. The gap between 1080p and 1440p at Low settings is 84.8 FPS, which is larger than the 62.3 FPS gap observed between 1440p and 4K. This non-linear drop indicates that at lower graphical loads, the GPU’s compute throughput becomes the dominant factor, while the Ryzen 9 7900X’s 24 threads are not the bottleneck in this horror title.

Ultra settings present the steepest scaling curve. The average frame rate at 1080p Ultra is 132.3 FPS, which falls to 91.8 FPS at 1440p and plummets to 59.9 FPS at 4K Ultra. The 4K result represents a 54.7% reduction from the 1080p Ultra figure. This steep decline suggests that the RDNA 4.0 architecture’s 4096 shading units and 128 ROPs are saturated by the combination of high resolution and maximum graphical fidelity. The data shows that 4K Ultra is the only configuration tested that dips below the 60 FPS threshold, making it a marginal experience for smooth gameplay.

Settings Recommendations

For players targeting a high refresh rate experience at 1920x1080, the Medium preset offers the best balance of visual quality and performance. The measured 251.4 FPS average at 1080p Medium is more than sufficient for any high-refresh display, and it represents a 42.5% improvement over the High preset’s 206.9 FPS. However, the jump from Medium to Low at 1080p yields 309.1 FPS, which is only a 23% gain, indicating diminishing returns for dropping settings further.

At 2560x1440, the High preset emerges as the sweet spot. The 150.8 FPS average at 1440p High is smooth and visually rich, while the Medium preset delivers 183.9 FPS. The difference between High and Medium at this resolution is 33.1 FPS, but the visual fidelity gains from High settings in a horror game—where lighting and shadow detail matter for atmosphere—justify the trade-off. The Ultra preset at 1440p drops to 91.8 FPS, which is still playable but sacrifices the headroom needed for 144 Hz displays.

For 4K gaming, the data strongly recommends the High preset. The 94.7 FPS average at 3840x2160 High is well above the 60 FPS target and provides a much better experience than the Ultra preset’s 59.9 FPS. The Medium preset at 4K offers 111.2 FPS, which is tempting, but the jump from Medium to High costs only 16.5 FPS while providing substantial visual improvements. The Low preset at 4K reaches 137.9 FPS, but it is unnecessary given that High already delivers a comfortable frame rate.

How This Combo Ranks

Within the benchmark database, this specific CPU-GPU pairing achieves a rank of 466 out of 1741 tested combinations for Downfall. This places the combo in the top 26.8% of all tested systems, which is a strong showing for a horror title that tends to favor GPU performance. The rank reflects the synergy between the Ryzen 9 7900X’s high single-thread performance and the RX 9070 XT’s raw rasterization power.

The CPU itself sits in the 93rd percentile against all tested processors, with an average benchmark score of 50556.

GPU Role

The Radeon RX 9070 XT is the dominant component in this pairing for Downfall, and its memory subsystem plays a critical role in the observed scaling. With 16 GB of GDDR6 memory and a 256-bit bus, the card delivers 644.6 GB/s of bandwidth. This is sufficient to handle the 4K High preset’s 94.7 FPS average without stuttering, but the Ultra preset at 4K reveals the limits of the memory interface when combined with maximum texture quality and shadow detail.

The GPU’s clock behavior is also relevant. The base clock is 1660 MHz, with a game clock of 2400 MHz and a boost clock of 2970 MHz. The large delta between base and boost—1310 MHz—indicates that the card aggressively scales frequency under load, which helps maintain high frame rates in lighter scenes. The memory clock runs at 2518 MHz, translating to 20.1 Gbps effective, which is a high data rate that supports the 4K performance observed.

The architecture’s compute resources are substantial: 4096 shading units, 256 TMUs, and 128 ROPs. The pixel rate of 380.2 GPixel/s and texture rate of 760.3 GTexel/s explain why the card excels at 1080p and 1440p, where fill-rate limits are less likely to be hit. However, the 4K Ultra result of 59.9 FPS suggests that the 128 ROPs become a bottleneck when pixel throughput demands peak, as evidenced by the 54.7% drop from 1080p Ultra. The FP32 performance of 48.66 TFLOPS is high enough for the horror game’s shader work, but the data indicates that memory bandwidth and ROP throughput are the constraining factors at maximum settings.

The card’s 304 W TDP and PCIe 5.0 x16 interface provide ample bandwidth to the CPU, and the measured results confirm that the system is not suffering from interface limitations. The GPU’s DirectX 12 Ultimate support aligns with the game’s rendering requirements, and the 82nd percentile ranking against all GPUs validates its position as a high-end part that pairs well with the 93rd percentile CPU.
