Downfall

The AMD Ryzen 7 5700X3D paired with the AMD Radeon RX 6600 XT delivers a compelling 1080p experience in Downfall, but the data reveals a sharp performance cliff as resolution climbs. This combination ranks in the 74th percentile of all tested combos for this title, suggesting a balanced, mid-range pairing that is clearly GPU-limited at higher resolutions. The measured frames per second (FPS) across the board tell a consistent story: this is a setup built for high-refresh 1080p gaming, with the GPU heavily dictating the performance ceiling.

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

The FPS scaling from 1920x1080 to 3840x2160 is dramatic and reveals a classic GPU-bound scenario. At Low settings, the average FPS falls from 193.9 at 1080p to 84 at 4K, a reduction of more than half. This steep decline indicates that the Radeon RX 6600 XT is the primary bottleneck; as pixel count quadruples, the GPU’s shading units and memory bandwidth are overwhelmed.

The pattern holds across all settings. At High, the drop is from 125.9 FPS at 1080p to 54.9 at 4K. The Ultra preset shows an even more severe collapse, plummeting from 78.3 FPS at 1080p to just 34.6 at 4K. Notably, the gap between Low and Ultra at 4K is a massive 49.4 FPS, while at 1080p that same gap is 115.6 FPS. This widening spread suggests that at lower resolutions, the CPU has more headroom to feed frames, but at 4K, the GPU's raw throughput becomes the sole limiting factor.

The 2560x1440 results sit predictably in between, with the High preset achieving 88.6 FPS and Ultra falling to 59.6 FPS. The data implies that the Ryzen 7 5700X3D’s 8 cores and 16 threads are more than sufficient to keep the GPU fed at 1080p, but the RX 6600 XT’s 8 GB of VRAM and 256.0 GB/s bandwidth are the ceiling for 1440p and 4K. For a horror title where smoothness is paramount, the 4K Ultra numbers are simply not viable.

A: Yes, particularly at 4K. The RX 6600 XT's average benchmark score of 27985 places it just 0.1% behind the GTX 980 Ti. The FPS data confirms this, as performance drops by 56.7% from 1080p to 4K on Low settings, indicating the GPU is the limiting component.

Q: What is the FPS difference between Low and Ultra at 1440p?

A: At 2560x1440, the Low preset achieves 134.9 FPS, while Ultra drops to 59.6 FPS. This represents a difference of 75.3 FPS, showing that the Ultra preset is nearly 2.3 times more demanding on the GPU.

Q: Does the CPU's cache configuration matter for this game?

A: The CPU has 96 MB of shared L3 cache, which is a significant amount. While the data does not directly measure game-specific cache impact, the strong 1080p results suggest that the 8-core, 16-thread setup with this large cache is sufficient to avoid bottlenecks in Downfall.

Q: What is the GPU's memory bandwidth and how does it affect 4K performance?

A: The RX 6600 XT has a 128-bit memory bus with 256.0 GB/s bandwidth. At 4K, the High preset only reaches 54.9 FPS, and Ultra falls to 34.6 FPS. This indicates that the memory bandwidth is insufficient for the high pixel throughput required at 4K, contributing to the severe FPS drop.

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

At 1920x1080, the RX 6600 XT shows its strength. Low settings hit 193.9 FPS, Medium achieves 154.3 FPS, and High reaches 125.9 FPS. Even the demanding Ultra preset maintains 78.3 FPS. These numbers indicate a smooth, high-refresh experience for all presets.

Moving to 2560x1440, the strain becomes visible. Low settings still deliver 134.9 FPS, and Medium is respectable at 114 FPS. High drops to 88.6 FPS, which is still playable. Ultra, however, falls to 59.6 FPS, which is borderline for a horror game where frame pacing is critical.

At 3840x2160, the GPU is clearly overtaxed. Low settings produce 84 FPS, but Medium drops to 67.2 FPS. High falls below the 60 FPS threshold to 54.9 FPS, and Ultra is nearly unplayable at 34.6 FPS. The progression from Low to Ultra at 4K shows a consistent 15-20% performance hit per settings tier, demonstrating the GPU's limited headroom at this resolution.

The full dataset shows a clear hierarchy: 1080p is the sweet spot, 1440p requires settings compromises, and 4K is only viable on Low settings for a playable frame rate.

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

The AMD Radeon RX 6600 XT is a RDNA 2.0 part with 8 GB of GDDR6 memory on a 128-bit bus. Its boost clock of 2589 MHz and game clock of 2359 MHz are relatively high, but the 256.0 GB/s bandwidth is the critical limiter. The 64 ROPs and 2048 shading units are sufficient for 1080p, but the pixel rate of 165.7 GPixel/s is not enough for high-fidelity 4K.

The GPU's average benchmark score of 27985 places it at the 71st percentile, with the NVIDIA GeForce GTX 980 Ti as its closest rival at 0.1% higher. This close competition is reflected in Downfall's performance, where the card behaves like a mid-range 1080p champion. The 8 GB VRAM capacity is not directly tested in the FPS data, but it is a likely contributor to the steep drop at 4K Ultra, where texture and geometry data exceed the memory bus's effective throughput.

The FP32 performance of 10.60 TFLOPS suggests adequate raw compute for the game's horror visuals, but the memory bandwidth bottleneck becomes apparent in the resolution scaling. The GPU's 160 W TDP and PCIe 4.0 x8 interface are standard for this class, but the data indicates that no amount of clock speed can overcome the bandwidth limitation at 4K.

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

For a 1080p display, the High preset at 125.9 FPS is the optimal balance of visual fidelity and performance. It is 51.4% faster than Ultra (78.3 FPS) while retaining significantly better visuals than Medium (154.3 FPS). For players prioritizing maximum frame rates, Low at 193.9 FPS is viable, but High is the recommended default.

At 1440p, the Medium preset at 114 FPS is the best choice. It is nearly twice as fast as Ultra (59.6 FPS) and only slightly slower than Low (134.9 FPS). High at 88.6 FPS is also acceptable, but the jump from Medium to High yields diminishing returns given the 22% FPS cost.

For 4K displays, the data is clear: use Low settings to achieve 84 FPS. Medium at 67.2 FPS is playable but not ideal for a horror game where smooth motion is essential. High (54.9 FPS) and Ultra (34.6 FPS) are not recommended, as they fall below the 60 FPS threshold and introduce noticeable stutter.

The overall recommendation is to target 1080p High for the best experience, as it maximizes the GPU's strengths while avoiding the resolution-related bottlenecks.

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

The AMD Ryzen 7 5700X3D is an 8-core, 16-thread processor with a base clock of 3.00 GHz and a boost clock of 4.10 GHz. Its 96 MB of shared L3 cache is a defining feature, and its Cinebench R23 multicore score of 22366 places it well above average. The single-core score of 3157 is strong for gaming, and the 3DMark single-thread score of 804 confirms solid per-core performance.

Given the FPS data, the CPU is clearly not a bottleneck at any resolution. At 1080p Low, the GPU produces 193.9 FPS, which the CPU can feed without issue. The 82nd percentile ranking against all CPUs supports this, with the nearest rival being the Intel Core i7-1360P at a 0.2% difference. The CPU's performance is effectively tied with the AMD Ryzen 5 7600X3D (0.3% delta) and the Intel Core i5-11600 (0.5% delta).

The 3D V-Cache architecture, while not explicitly named in the benchmarks, is implied by the 96 MB L3 cache. This large cache is likely beneficial in Downfall, as the game's horror environments may involve predictable asset access patterns. The 8 cores and 16 threads ensure that the CPU side of the equation is never a limiting factor, even when the GPU is struggling at 4K. The PassMark multithread score of 26318 further confirms the CPU's capability to handle background tasks without impacting game performance.

In summary, the CPU provides a robust foundation, but the GPU is the determining factor for overall game performance. The combo rank of 1298 reflects this, as the CPU's strength is only fully realized when paired with a more capable GPU.
