GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with the Navi 23 chip, fabricated on a 7 nm process at TSMC with 11,060 million transistors. Its memory configuration is 8 GB of GDDR6 on a 128-bit bus, delivering 280.3 GB/s of bandwidth. The GPU's clocks are notably high: a base of 2055 MHz, a game clock of 2410 MHz, and a boost of 2635 MHz. Memory runs at 2190 MHz, which translates to 17.5 Gbps effective.

These specifications directly influence the measured FPS in Downfall. The GPU's 2048 shading units and 64 ROPs, combined with a pixel rate of 168.6 GPixel/s and texture rate of 337.3 GTexel/s, provide the raw throughput needed for this game's rendering. The 10.79 TFLOPS of FP32 compute is the theoretical ceiling for shader work. In practice, the data shows the GPU handles 1080p and 1440p well at most settings, but the 4K Ultra result of 39.4 FPS reveals the 8 GB frame buffer and 128-bit memory interface become limiting factors at higher resolutions.

The GPU's 72nd percentile ranking among all GPUs, with an average benchmark score of 29024, places it in a competitive tier. Its nearest rival, the AMD Radeon RX 6800M, scores 29011 with a 0% delta — a statistical dead heat. The RX 470 is 0.1% behind at 28996, while the Intel Arc A370M is 0.5% behind at 29175. This tight clustering suggests the 6650 XT is well-matched against these alternatives in synthetic tests, but the game-specific data reveals how memory bandwidth and capacity affect real-world performance in Downfall.

Settings Recommendations

The measured data provides clear guidance on which preset offers the best experience at each resolution. At 1920x1080, the Low preset delivers 197.4 FPS, while Medium drops to 162.6 FPS and High falls to 132.6 FPS. The Ultra preset drops significantly to 83.4 FPS. For most players, the High preset at 1080p offers a strong balance — 132.6 FPS is well above smooth thresholds, and the visual upgrade from Medium is substantial given the 30 FPS gap.

At 2560x1440, the pattern shifts. Low yields 141.1 FPS, Medium 114.5 FPS, and High 94.9 FPS. Ultra falls to 58.5 FPS. The High preset at 1440p is still playable at nearly 95 FPS, but the Medium setting at 114.5 FPS might be preferable for those prioritizing headroom. The Ultra preset at 1440p, at 58.5 FPS, is borderline — it dips below the 60 FPS mark, which may cause noticeable stutter in a horror game where smooth motion matters for atmosphere.

At 3840x2160, the data tells a different story. Low yields 86.1 FPS, Medium 70.9 FPS, and High 58.9 FPS. Ultra plummets to 39.4 FPS. The High preset at 4K, at 58.9 FPS, is just under the 60 FPS target, while Medium at 70.9 FPS provides a comfortable margin. For 4K, the Medium preset appears to be the sweet spot — it maintains playable frame rates while offering better visual fidelity than Low, and it avoids the severe penalty of Ultra.

How This Combo Ranks

The combo rank of 1138 out of 1741 tested combinations places this system in the 65th percentile of all tested combos in Downfall. This means roughly one-third of tested configurations perform worse, while two-thirds perform better. The rank reflects the balance between the CPU's strong compute and the GPU's mid-tier positioning.

The CPU's 83rd percentile ranking among all CPUs, with an average benchmark score of 26574, is a significant contributor. Its nearest rival, the AMD EPYC 8024P, scores 26555 with a 0.1% delta, while the Intel Core i9-11900K scores 26546, also 0.1% behind. The AMD Ryzen 5 7600 is 0.2% ahead at 26617, and the Intel Core i9-12900HK is 0.4% ahead at 26672. This indicates the 5800X3D is competitive with modern chips despite being from the 5000 series.

The GPU's 72nd percentile ranking, with an average score of 29024, is lower than the CPU's percentile, suggesting the GPU is the more limiting factor in this combo. The delta between the GPU and its nearest rivals is minimal — the RX 6800M at 0% and the RX 470 at 0.1% — but the overall combo rank of 1138 indicates that in Downfall specifically, the balance tips toward CPU-bound scenarios at lower resolutions and GPU-bound at higher ones.

CPU Role

The AMD Ryzen 7 5800X3D is a 5000 series processor with 8 cores and 16 threads, based on the Zen 3 architecture with the Vermeer codename. It operates at a base clock of 3.40 GHz and boosts to 4.50 GHz, with a TDP of 105 W. The chip uses AMD Socket AM4 and supports DDR4 memory in dual-channel configuration with a bandwidth of 51.2 GB/s. The 7 nm process from TSMC houses 8,850 million transistors on a 74 mm² die.

The cache hierarchy is noteworthy: 64 KB of L1 per core, 512 KB of L2 per core, and a massive 96 MB of shared L3 cache. This large L3 cache is a defining feature of the 5800X3D and helps in gaming workloads. The benchmark data shows strong multithreaded performance: Cinebench R23 multicore scores 24063, while single-core scores 3397. Geekbench multicore hits 11061 and single-core 2116. Passmark multithread scores 28309, with single-thread at 3234.

In Downfall, the CPU's role is evident from the FPS scaling across resolutions. At 1080p, the Low preset achieves 197.4 FPS, which approaches CPU limits for this processor. The 3dmark 16-thread score of 7299 and max-thread score of 7285 indicate the chip can handle heavy thread loads, but the game's engine likely doesn't scale perfectly to 16 threads. The single-thread score of 884 in 3dmark suggests per-core performance is adequate but not exceptional, which could explain why frame rates cap around 197 FPS even at Low settings.

Measured FPS Breakdown

The measured data provides a comprehensive view of performance across three resolutions and four settings. At 1920x1080, the average FPS ranges from 197.4 (Low) to 83.4 (Ultra). The progression is Linear: Low at 197.4, Medium at 162.6, High at 132.6, and Ultra at 83.4. The gap between High and Ultra is 49.2 FPS, the largest drop in the 1080p tier, indicating Ultra settings introduce a significant rendering overhead.

At 2560x1440, the range narrows. Low yields 141.1 FPS, Medium 114.5 FPS, High 94.9 FPS, and Ultra 58.5 FPS. The drop from High to Ultra is 36.4 FPS, still substantial but less severe than at 1080p. The 1440p results show a consistent 30-40 FPS penalty for each step up in settings, except between Medium and High, which is 19.6 FPS.

At 3840x2160, the performance compresses further. Low produces 86.1 FPS, Medium 70.9 FPS, High 58.9 FPS, and Ultra 39.4 FPS. The gaps between settings are smaller in absolute terms: Low to Medium is 15.2 FPS, Medium to High is 12 FPS, and High to Ultra is 19.5 FPS. This compression indicates the GPU is becoming the bottleneck across all settings at 4K, as even Low settings cannot fully utilize the CPU's capabilities.

Resolution Scaling

The data reveals how FPS scales from 1080p to 4K, and the pattern shifts depending on settings. At Low settings, the FPS drops from 197.4 at 1080p to 141.1 at 1440p, a 28.5% reduction, and further to 86.1 at 4K, a 56.4% reduction from 1080p. This suggests the CPU is partially limiting at 1080p Low, as the GPU has headroom that gets consumed as resolution increases.

At Medium settings, the scaling is similar: 162.6 at 1080p drops to 114.5 at 1440p (29.6% reduction) and 70.9 at 4K (56.4% reduction). The consistent percentage drops across Low and Medium indicate the GPU is the primary limiter even at lower settings, with the CPU providing enough throughput to avoid becoming the bottleneck until frame rates exceed roughly 140 FPS.

At High settings, the drop from 1080p to 1440p is 28.4% (132.6 to 94.9), and to 4K it's 55.6% (132.6 to 58.9). The Ultra settings show a different pattern: 83.4 at 1080p drops to 58.5 at 1440p (29.9% reduction) and 39.4 at 4K (52.8% reduction). The slightly smaller percentage drop at 4K Ultra suggests the Ultra settings are so demanding that resolution scaling becomes less linear, with the GPU's 8 GB frame buffer and 280.3 GB/s bandwidth being the limiting factors.

The limiting component analysis points to the GPU as the primary constraint at higher resolutions and settings. The CPU's 96 MB L3 cache and high single-thread performance (3dmark single-thread 884, Cinebench R23 single-core 3397) allow it to keep up at lower resolutions, but the GPU's 128-bit memory interface and 8 GB capacity create a ceiling that becomes evident at 4K, where even Low settings only reach 86.1 FPS. This is a balanced combo for 1080p and 1440p gaming, but the data clearly shows the GPU is the bottleneck when pushing to 4K.
