Downfall

The AMD Ryzen 7 9850X3D and AMD Radeon RX 6650 XT combination delivers a playable experience across most of Downfall’s settings, but the data clearly indicates a preference for the Medium preset as the optimal balance. At 1080p, the Medium preset produces an average of 162 FPS, which is 29 frames higher than High and 79 frames higher than Ultra, while remaining comfortably above the 60 FPS threshold for smooth horror gameplay. The Low preset pushes performance to 199 FPS, but the visual degradation in a horror title—where atmosphere and lighting are critical—makes this trade-off less appealing; Medium retains enough fidelity to preserve the intended mood while offering a significant FPS cushion over the High and Ultra settings. At 1440p, the Medium preset again stands out with 116 FPS average and a minimum of 99 FPS, ensuring no noticeable stutter during intense sequences, whereas High drops to 95 FPS and Ultra falls to 59 FPS, the latter being borderline for a genre that relies on sudden movement. The 4K Medium preset yields 72 FPS with a minimum of 61 FPS, which is just above the playability line, but the 4K High preset at 59 FPS and 4K Ultra at 37 FPS suggest that pushing beyond Medium at this resolution invites performance risks. For the best experience per the measured rows, the Medium preset at 1080p or 1440p offers the highest consistent frame rates without sacrificing the visual quality that Downfall’s horror atmosphere demands; at 4K, Medium is the only viable option that keeps the average above 60 FPS.

GPU Role

The Radeon RX 6650 XT’s 8 GB of GDDR6 memory on a 128-bit bus with 280.3 GB/s bandwidth plays a decisive role in Downfall’s performance, as the game’s measured FPS scales directly with the GPU’s capabilities across resolutions. The card’s boost clock of 2635 MHz and game clock of 2410 MHz, built on the RDNA 2.0 architecture with 2048 shading units, 128 TMUs, and 64 ROPs, provides a solid foundation for a 2016 horror title that is not exceptionally demanding by modern standards. The GPU’s 10.79 TFLOPS of FP32 compute and 32 ray accelerators contribute to the rendering pipeline, though Downfall’s release date suggests it relies more on traditional rasterization than ray tracing. The benchmark results show that the GPU becomes the limiting factor at higher resolutions and settings: at 1080p Low, the CPU’s strength (8 cores, 16 threads, Zen 5 architecture) allows the GPU to reach 199 FPS, but at 4K Ultra, the frame rate collapses to 37 FPS, indicating that the RX 6650 XT’s memory bandwidth and compute resources are stretched thin. The card’s 64 ROPs and 168.6 GPixel/s pixel rate help maintain fill rates, yet the 8 GB VRAM capacity appears sufficient for Downfall’s textures, as no VRAM-related stutter is evident in the min FPS data, which remains above 60 FPS only at Medium settings across all resolutions. The GPU’s percentile ranking versus all GPUs stands at 65, placing it in the upper-midrange tier, and its nearest rivals—such as the NVIDIA Tesla K40m with a 0.6% score difference—confirm that it operates in a competitive but not top-tier segment. The data shows that the RX 6650 XT’s clock speeds are consistently utilized, but the transition from 1440p High (95 FPS) to 4K High (59 FPS) highlights that the card’s 280.3 GB/s bandwidth is the likely bottleneck, as the CPU’s 89.6 GB/s memory bandwidth and 96 MB L3 cache remain underutilized at those settings.

Resolution Scaling

Frame rates drop sharply as resolution increases from 1080p to 4K, and the pattern reveals a clear shift in the limiting component. At 1080p Low, the combo delivers 199 FPS, which drops to 142 FPS at 1440p Low—a 28.6% reduction—and further to 88 FPS at 4K Low, representing a 38% drop from 1440p. This scaling suggests that at lower settings, the CPU’s high single-thread performance (2228 in Cinebench R23 single-core) can feed the GPU adequately at 1080p, but the GPU begins to struggle as pixel count increases. The Medium preset tells a similar story: 162 FPS at 1080p falls to 116 FPS at 1440p (a 28.4% decrease) and then to 72 FPS at 4K (a 37.9% decrease from 1440p), with the minimum FPS at 4K Medium (61 FPS) closely tracking the average, indicating sustained GPU load. The High preset shows 133 FPS at 1080p, 95 FPS at 1440p (a 28.6% drop), and 59 FPS at 4K (a 37.9% drop), mirroring the scaling pattern of Medium and suggesting that the GPU’s compute and memory throughput are the dominant constraints, not the CPU. The Ultra preset exhibits the most dramatic scaling: 83 FPS at 1080p, 59 FPS at 1440p (a 28.9% drop), and 37 FPS at 4K (a 37.3% drop), with the 4K result being nearly unplayable. The consistent percentage drops across settings—roughly 28% from 1080p to 1440p and 38% from 1440p to 4K—indicate that the limiting component is the RX 6650 XT, as the Ryzen 7 9850X3D’s performance (92nd percentile among all CPUs) would not degrade in this proportional manner if it were the bottleneck. The data shows that at 1080p, the CPU’s headroom allows the GPU to run at its peak, but at 4K, the GPU’s 8 GB memory and 128-bit bus become insufficient, with the 4K Ultra result of 37 FPS being 55% lower than the 1080p Ultra result, a gap that cannot be attributed to CPU limitations given the processor’s 16 threads and 5.60 GHz boost clock.

How This Combo Ranks

The combination of the AMD Ryzen 7 9850X3D and AMD Radeon RX 6650 XT ranks 2424 out of 3716 tested combos in Downfall, placing it in the 34.8th percentile of all configurations. This mid-pack ranking is somewhat counterintuitive given the CPU’s strong standalone performance—the Ryzen 7 9850X3D sits at the 92nd percentile among all CPUs, with an average benchmark score of 58386, slightly ahead of the Intel Core i9-14900 by 0.5% and nearly matching the Intel Xeon Platinum 8260M within 0.1%. However, the GPU’s lower standing drags the combo down: the RX 6650 XT ranks at the 65th percentile among all GPUs, with an average benchmark score of 19765, which is 0.6% behind the NVIDIA Tesla K40m and 0.7% ahead of the AMD FirePro D300. This disparity between CPU and GPU performance explains the ranking—the processor is capable of far more than the graphics card can deliver, and in Downfall, the GPU becomes the limiting factor at higher resolutions, as evidenced by the FPS scaling data. The combo’s rank of 2424 indicates that it outperforms roughly 35% of tested configurations, but it falls behind systems with more balanced or higher-tier GPUs, even if those systems have weaker CPUs. For instance, the data shows that the CPU’s nearest rivals in raw compute (like the Intel Xeon w5-2545, which is 0.2% faster) would not necessarily produce better gaming results if paired with a stronger GPU, whereas this pairing’s bottleneck is clearly the graphics card. The ranking suggests that users seeking higher positions in Downfall’s benchmark hierarchy would need to prioritize GPU upgrades over CPU, as the Ryzen 7 9850X3D’s 8 cores and 96 MB L3 cache provide ample headroom that the RX 6650 XT cannot exploit, particularly at 4K where the frame rate drops to 59 FPS on High settings.

Measured FPS Breakdown

1080p (1920x1080): The Low preset delivers the highest average at 199 FPS, with no min/max recorded. Medium averages 162 FPS, with a minimum of 138 FPS and a maximum of 187 FPS, providing a stable frame rate with a 49 FPS variance. High averages 133 FPS, and Ultra drops to 83 FPS, showing that the jump from High to Ultra costs 50 FPS (a 37.6% reduction). The Medium preset’s minimum of 138 FPS ensures no noticeable frame drops during gameplay, while the Low preset’s 199 FPS average is the only setting that approaches 200 FPS.

1440p (2560x1440): Low averages 142 FPS, representing a 28.6% drop from the 1080p Low result. Medium averages 116 FPS, with a minimum of 99 FPS and a maximum of 133 FPS, keeping the minimum just below 100 FPS. High averages 95 FPS, which is 20 FPS lower than Medium, and Ultra averages 59 FPS, making it the only 1440p setting below 60 FPS. The Medium preset’s min-max range of 99–133 FPS shows a 34 FPS spread, indicating consistent performance without severe stuttering.

4K (3840x2160): Low averages 88 FPS, a 38% drop from the 1440p Low result, but remains playable. Medium averages 72 FPS, with a minimum of 61 FPS and a maximum of 83 FPS, which is the only 4K setting with a reported minimum above 60 FPS. High averages 59 FPS, just below the 60 FPS threshold, and Ultra averages 37 FPS, which is nearly unplayable. The scaling from 1440p to 4K is consistent: Low drops from 142 to 88 FPS (38%), Medium from 116 to 72 FPS (38%), High from 95 to 59 FPS (38%), and Ultra from 59 to 37 FPS (37%). This uniform percentage drop across all settings confirms that the GPU is the limiting factor at 4K, as the CPU’s performance headroom cannot compensate for the increased pixel load.
