Downfall

How This Combo Ranks

The AMD Ryzen 7 7800X3D paired with the AMD Radeon RX 6600 ranks 1373 out of 1741 tested combos in Downfall. That places this configuration in the lower-middle portion of the database, meaning roughly 79% of tested combinations deliver higher average frame rates. The ranking reflects a significant bottleneck: the CPU sits in the 87th percentile among all processors, while the GPU sits in only the 69th percentile among all graphics cards. The data suggests the RX 6600 is the limiting factor in this pairing.

The CPU itself is a strong performer. Its average benchmark score of 31580 places it narrowly ahead of the Intel Core i7-12700F, which scores 31543, a margin of just 0.1%. It also edges out the AMD Ryzen 9 5980HX by 0.3% and the AMD Ryzen 7 8700G by 0.6%. In multithreaded workloads, the 7800X3D posts a Cinebench R23 multicore score of 29149 and a Geekbench multicore score of 15101. Single-thread performance is equally capable, with a Geekbench single-core score of 2725 and a Cinebench R23 single-core score of 4115. These figures indicate the processor is far from being the constraint in Downfall's frame rate results.

The GPU, by contrast, is a mid-range part. Its average benchmark score of 25235 is statistically tied with the AMD Radeon 890M, which scores 25246 (a 0% difference), and the AMD Radeon RX 6700M, which scores 25180 (a 0.2% difference). The RX 6600 trails the NVIDIA GeForce RTX 3060 Ti by just 0.5%, but all four cards are clustered within a narrow performance band. The measured frame rates in Downfall reflect this GPU ceiling; the CPU has ample headroom to push higher numbers if a more powerful graphics card were installed.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with the Navi 23 chip, fabricated on a 7 nm process at TSMC. It carries 8 GB of GDDR6 memory on a 128-bit bus, delivering a memory bandwidth of 224.0 GB/s. The GPU has 1792 shading units, 112 texture mapping units, and 64 raster operation pipelines. Clock speeds are moderate: a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. The memory runs at 1750 MHz, which translates to 14 Gbps effective.

In Downfall, the GPU's role is decisive. At 1080p with Low settings, the combo reaches 175.1 FPS, but this drops to 73.6 FPS at Ultra — a reduction of 101.5 FPS. The pattern is consistent across resolutions. At 1440p, Low produces 126.8 FPS while Ultra yields 54.2 FPS. At 4K, the spread narrows in absolute terms: Low hits 79.1 FPS, Ultra falls to 34.2 FPS. The GPU's 8 GB frame buffer and its pixel rate of 159.4 GPixel/s are the primary drivers of these results. The texture rate of 279.0 GTexel/s also matters; higher settings increase texture detail, which directly taxes the 112 TMUs.

The GPU's FP32 throughput of 8.928 TFLOPS is modest by modern standards, and the data shows this becomes the binding constraint as settings rise. The CPU's 96 MB of shared L3 cache, a hallmark of the 7800X3D's 3D V-Cache design, does not compensate for the GPU's limits in this title. The measured FPS at Ultra settings across all resolutions indicates the RX 6600 is saturated, not the processor.

Resolution Scaling

The frame rate deltas from 1080p to 4K reveal where the bottleneck shifts. At Low settings, the combo delivers 175.1 FPS at 1080p, 126.8 FPS at 1440p, and 79.1 FPS at 4K. That is a 48.3% drop from 1080p to 1440p, and a 37.6% drop from 1440p to 4K. The scaling is steep, indicating the GPU is heavily loaded even at Low. At Medium settings, the numbers are 144.4 FPS at 1080p, 103.2 FPS at 1440p, and 64.6 FPS at 4K. The drop from 1080p to 1440p is 28.5%, and from 1440p to 4K is 37.4%.

At High settings, 1080p yields 118 FPS, 1440p yields 81.7 FPS, and 4K yields 50.7 FPS. The 1080p-to-1440p decline is 30.8%, while the 1440p-to-4K decline is 37.9%. At Ultra, the pattern shifts: 73.6 FPS at 1080p, 54.2 FPS at 1440p, and 34.2 FPS at 4K. The 1080p-to-1440p drop is 26.4%, and the 1440p-to-4K drop is 36.9%. Across every setting, the 1440p-to-4K penalty is larger than the 1080p-to-1440p penalty. This suggests pixel count scaling outpaces the GPU's raw fill rate capabilities.

The data indicates the CPU is not the limiter at any resolution. The 7800X3D's single-thread performance — a PassMark single-thread score of 3759 and a 3DMark single-thread score of 959 — is sufficient to feed the RX 6600 at all tested settings. The frame rate collapses are consistent with GPU-bound behavior. At 4K Ultra, the combo produces just 34.2 FPS, a figure that highlights the RX 6600's limitations with high pixel counts and heavy shading loads.

Measured FPS Breakdown

At 1920x1080, the combo delivers 175.1 FPS on Low, 144.4 FPS on Medium, 118 FPS on High, and 73.6 FPS on Ultra. The step from Low to Medium costs 30.7 FPS, from Medium to High costs 26.4 FPS, and from High to Ultra costs 44.4 FPS. The Ultra setting imposes a disproportionate penalty, suggesting a specific rendering feature or memory usage spike.

At 2560x1440, the results are 126.8 FPS on Low, 103.2 FPS on Medium, 81.7 FPS on High, and 54.2 FPS on Ultra. The gaps are 23.6 FPS from Low to Medium, 21.5 FPS from Medium to High, and 27.5 FPS from High to Ultra. The Ultra penalty is again the largest single step, but the overall range is compressed compared to 1080p.

At 3840x2160, the numbers drop to 79.1 FPS on Low, 64.6 FPS on Medium, 50.7 FPS on High, and 34.2 FPS on Ultra. The differences are 14.5 FPS from Low to Medium, 13.9 FPS from Medium to High, and 16.5 FPS from High to Ultra. At 4K, even Low settings fall below the 80 FPS mark, and Ultra barely reaches playable territory for a horror title. The 4K High result of 50.7 FPS and the 4K Ultra result of 34.2 FPS both fall short of the 60 FPS threshold commonly considered smooth.

The data shows a clear trend: the RX 6600's performance degrades predictably as resolution and settings increase. The 1080p Low result of 175.1 FPS is the only configuration that clears 170 FPS. No configuration at 4K exceeds 79.1 FPS. The GPU's 8 GB memory capacity and 224.0 GB/s bandwidth appear adequate for this game's demands, but the shading and rasterization throughput limits frame rates at higher quality presets.

Settings Recommendations

The measured data suggests that Medium settings at 1080p offer the best balance for this combo. The 144.4 FPS result at 1080p Medium is 29.7% higher than the 118 FPS at High, while the visual quality difference between Medium and High is typically smaller than the performance gap. For players prioritizing smoothness, 1080p Low at 175.1 FPS is the fastest option, but it sacrifices visual fidelity.

At 1440p, Medium provides 103.2 FPS, which is above the 60 FPS threshold and still retains a reasonable level of detail. High at 1440p drops to 81.7 FPS, which remains playable but approaches the point where frame pacing becomes noticeable in a horror title. Ultra at 1440p yields 54.2 FPS, which is below the 60 FPS mark and not recommended for consistent gameplay.

At 4K, no setting achieves 60 FPS. Low produces 79.1 FPS, Medium produces 64.6 FPS, High produces 50.7 FPS, and Ultra produces 34.2 FPS. For 4K play, Medium is the only setting that clears 60 FPS, and it does so by a slim margin. High and Ultra are best avoided at this resolution. The data indicates 1080p Medium or 1440p Medium are the most sensible presets, with the former offering 144.4 FPS and the latter offering 103.2 FPS. Ultra settings are only viable at 1080p, where the 73.6 FPS result is still above playable thresholds but significantly lower than lower presets.
