Downfall

The AMD Ryzen 7 5700X paired with the AMD Radeon RX 6600 XT is a mid-range combination that handles Downfall competently, though the data reveals a clear performance ceiling at higher resolutions. The 8-core, 16-thread Zen 3 processor provides ample headroom, while the RDNA 2 graphics card becomes the primary bottleneck as pixel count rises. This analysis breaks down the measured frame rates, settings scaling, and where this combo stands among the 1,741 tested configurations.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and tells a clear story about which component is doing the heavy lifting. At 1080p with Low settings, the combo produces 191.6 FPS. Moving to 1440p Low drops that to 133.4 FPS, a 30.4% reduction, and 4K Low lands at 84.9 FPS, which is 55.7% below the 1080p result. This pattern indicates the RX 6600 XT is the limiting factor as resolution increases; the CPU’s 16 threads are more than sufficient to feed the GPU at lower resolutions, but the graphics card’s 128-bit memory bus and 256.0 GB/s bandwidth struggle to keep up with the 3840x2160 pixel count.

The gap between settings widens at higher resolutions, which further confirms GPU dominance. At 1080p, the spread from Low to Ultra is 111.6 FPS (191.6 down to 80.0). At 1440p, that spread shrinks to 78.3 FPS (133.4 down to 55.1). At 4K, the spread compresses to 46.1 FPS (84.9 down to 38.8). This compression happens because the GPU is already saturated at 4K, so lowering settings yields diminishing returns; the pixel throughput limit is hit before the rendering complexity becomes the primary constraint. The data suggests that 1440p is the sweet spot for this pairing, as it balances the CPU’s ability to push high frame rates with the GPU’s capacity to render detailed scenes without collapsing.

GPU Role

The RX 6600 XT is built on the Navi 23 chip using RDNA 2.0 architecture, with 8 GB of GDDR6 memory on a 128-bit bus. The base clock is 1968 MHz, the game clock is 2359 MHz, and the boost clock reaches 2589 MHz, with memory running at 2000 MHz (16 Gbps effective). These clocks are relatively high for the class, and the 2048 shading units help sustain performance in Downfall’s horror environments, which tend to feature dark, texture-heavy scenes. The 64 ROPS and 331.4 GTexel/s texture rate are adequate for 1080p and 1440p, but the 256.0 GB/s bandwidth becomes a limiting factor at 4K.

The GPU’s benchmark scores place it in the 71st percentile among all GPUs, with an average score of 27985. Its nearest rival is the NVIDIA GeForce GTX 980 Ti, which scores 27956, a delta of 0.1% — essentially a tie. The RTX 3070 scores 28238, which is 0.9% higher, showing the RX 6600 XT is within striking distance of a much higher-tier card in synthetic tests, but the measured FPS in Downfall tells a more nuanced story. The 8 GB VRAM is sufficient for this 2016 title, as none of the settings presets appear to exceed it, but the memory bus width is the structural weakness that caps 4K performance.

FAQ

*Q: Is the Ryzen 7 5700X bottlenecking the RX 6600 XT in Downfall?*

A: No. The CPU’s 16 threads and 32 MB of L3 cache provide more than enough throughput. At 1080p Low, the combo hits 191.6 FPS, and the frame rate drops are consistent with GPU limitations as resolution increases, not CPU stalls.

Q: How does this combo compare to the CPU’s nearest rivals in synthetic benchmarks?

A: The Ryzen 7 5700X has an average benchmark score of 26214, which is 0.1% higher than the Intel Core i9-11900KF (26196) and 0.2% higher than the AMD Ryzen 5 5500GT (26161). It trails the AMD Ryzen 7 PRO 6850U and the AMD Ryzen 5 7600X by 0.2% each.

*Q: What is the best resolution for this combo in Downfall?*

A: 1440p with High settings delivers 93.5 FPS, which is smooth and visually detailed. 1080p Ultra hits 80.0 FPS, but 1440p High offers a better balance of image quality and frame rate.

Q: How much performance is lost going from 1080p to 4K at the same settings?

A: At High settings, 1080p yields 129.4 FPS, while 4K yields 56.8 FPS, a drop of 56.1%. The loss is even larger on Ultra, where 1080p’s 80.0 FPS falls to 38.8 FPS at 4K, a 51.5% reduction.

Q: Is the RX 6600 XT’s VRAM sufficient for this game?

A: Yes. The 8 GB GDDR6 memory is more than enough for Downfall, which is a 2016 release. The limiting factor is not capacity but the 128-bit memory bus, which caps bandwidth at 256.0 GB/s.

Q: Does the combo rank highly among all tested configurations?

A: It ranks 1260 out of 1741 combos, placing it in the lower-middle tier. This is expected given the RX 6600 XT’s 71st percentile GPU ranking and the CPU’s 83rd percentile ranking.

Measured FPS Breakdown

At 1080p, the RX 6600 XT shows strong performance across all presets. Low settings produce 191.6 FPS, Medium 154.5 FPS, High 129.4 FPS, and Ultra 80.0 FPS. The jump from High to Ultra is significant — a 49.4 FPS drop — indicating that Ultra settings introduce rendering effects that heavily tax the GPU’s 10.60 TFLOPS FP32 compute. The 1080p results are all playable, even Ultra, which stays above 60 FPS.

At 1440p, the frame rates remain respectable. Low hits 133.4 FPS, Medium 111.5 FPS, and High 93.5 FPS. Ultra drops to 55.1 FPS, which is below the 60 FPS threshold for smooth gameplay. The drop from High to Ultra at 1440p is 38.4 FPS, similar to 1080p’s pattern, but the absolute values are lower, confirming that the GPU is running out of headroom.

At 4K, the picture changes dramatically. Low yields 84.9 FPS, Medium 69.0 FPS, and High 56.8 FPS. Ultra falls to 38.8 FPS, which is barely playable for a horror title that benefits from steady frame pacing. The gap between Low and Medium at 4K is 15.9 FPS, while the gap between Medium and High is 12.2 FPS, showing that each setting tier costs a similar amount of performance. The Ultra preset at 4K is the only configuration that dips below 40 FPS, making it the least viable option.

How This Combo Ranks

The combination ranks 1260 out of 1741 tested combos, placing it in the 72nd percentile of all configurations — meaning roughly 28% of tested combos perform worse. This is a solid mid-pack result. The CPU’s 83rd percentile ranking (higher than the GPU’s 71st) indicates the processor is not the weak link; the RX 6600 XT is the limiting component in this pairing. The GPU’s nearest rival, the GTX 980 Ti, scores nearly identically in synthetic tests (0.1% delta), but in Downfall the RX 6600 XT’s RDNA 2 architecture likely handles the horror game’s shader workload more efficiently, given the measured FPS are consistent with a modern mid-range card.

The combo’s rank is dragged down by the 4K results, where the 128-bit memory bus and 256.0 GB/s bandwidth cannot compete with higher-tier GPUs that have wider buses. At 1080p and 1440p, the combo would rank much higher, as the frame rates are competitive with more expensive pairings. The data suggests this is a 1080p/1440p build, not a 4K machine.

Settings Recommendations

For the best experience, 1080p High settings at 129.4 FPS is the clear winner — it provides a high frame rate with good visual fidelity, and the 49.4 FPS gap to Ultra is not worth the visual upgrade for a horror game that relies on atmosphere over graphical extremes. If you have a 1440p monitor, High settings at 93.5 FPS is the recommended preset; it stays well above 60 FPS and looks noticeably sharper than 1080p. Medium at 1440p (111.5 FPS) is a viable alternative if you prefer maximum smoothness over minor texture details.

Avoid Ultra at 1440p (55.1 FPS) and 4K (38.8 FPS) unless you have adaptive sync and can tolerate occasional dips. The 4K High setting (56.8 FPS) is borderline, but the frame rate is too close to 60 FPS to be reliable during intense scenes. For 4K, Low settings at 84.9 FPS is the only preset that offers a comfortable margin above 60 FPS, but the visual downgrade is severe. The pragmatic choice is to run 1440p High and enjoy Downfall as it was meant to be played — dark, tense, and smooth.
