Downfall

The AMD Ryzen 9 9900X paired with the Intel Arc B580 delivers a playable experience in Downfall at 1080p and 1440p, but 4K requires dropping to Medium or Low settings to stay above the 60 FPS threshold. The data shows a clear resolution scaling pattern: the combo excels at lower resolutions, where the CPU’s strong multi-threaded performance (32,172 in Cinebench R23 multi-core) keeps frame rates high, while the GPU’s 13.67 TFLOPS FP32 compute becomes the limiting factor at 4K. At Ultra settings, the game demands more than this pairing can consistently deliver beyond 1440p, with 4K Ultra averaging only 34 FPS—well below the playable threshold.

Measured FPS Breakdown

At 1920x1080, the combo clears the 60 FPS playable threshold across every preset. Low settings produce an average of 185 FPS, Medium hits 151 FPS (with a minimum of 128 and maximum of 174), High reaches 124 FPS, and even Ultra maintains a solid 77 FPS average. This resolution shows no bottleneck concerns; the Ryzen 9 9900X’s 12 cores and 24 threads, combined with the Arc B580’s 2560 shading units, keep frame delivery smooth and consistent. The gap between Low and Ultra is 108 FPS, indicating the GPU scales well with settings changes at this resolution.

At 2560x1440, performance remains playable but with more variation. Low settings average 132 FPS, Medium averages 108 FPS (minimum 92, maximum 124), and High averages 88 FPS. Ultra drops to 55 FPS, just 5 FPS below the 60 FPS threshold, making it the only non-playable preset at this resolution. The data shows a 77 FPS difference between Low and Ultra, a steeper drop than at 1080p, signaling that the Arc B580’s 456 GB/s memory bandwidth starts to feel constrained as pixel count rises. The Medium preset’s minimum of 92 FPS indicates that even in demanding scenes, the combo holds up well.

At 3840x2160, the picture changes dramatically. Low settings average 82 FPS, Medium averages 67 FPS (minimum 57, maximum 77), but High falls to 55 FPS and Ultra to 34 FPS. The playable settings here are Low and Medium, with Medium being the best choice for visual quality while staying above 60 FPS on average. The 33 FPS gap between Medium and High at 4K highlights a steep performance cliff, likely due to the GPU’s 192-bit memory bus and 12 GB GDDR6 capacity being pushed to their limits. The minimum of 57 FPS at Medium suggests occasional dips below 60, but the average remains playable. The difference between 1080p Ultra (77 FPS) and 4K Ultra (34 FPS) represents a 56% drop, emphasizing how resolution scaling disproportionately affects this GPU.

The AMD EPYC 7313 scores 57,399, just 0.2% lower, so it would also perform comparably. Higher-scoring alternatives like the Intel Xeon Platinum 8260M (58,323, 1.4% higher) or the AMD EPYC 9015 (57,555, 0.1% higher) fall within the same performance envelope, yielding no meaningful FPS differences in Downfall.

On the GPU side, the Arc B580’s nearest rivals show surprising parity. The NVIDIA GeForce RTX 2080 scores 22,895 (0.6% lower), the AMD Radeon RX 580 2048SP scores 23,061 (0.2% lower), and the NVIDIA GeForce RTX 3080 scores 23,172 (0.7% higher). This means a system with the Ryzen 9 9900X and any of these GPUs would produce nearly identical frame rates in Downfall. The NVIDIA P106-100 (23,249, 1% higher) is also close. In practical terms, swapping the Arc B580 for an RTX 3080 would not change the playable settings at any resolution—the 4K Medium average would remain around 67 FPS, and 1080p Ultra would still hit roughly 77 FPS.

For users considering this combo, the data suggests that CPU choice among these rivals has minimal impact on Downfall performance. The game is more GPU-dependent at higher resolutions, as evidenced by the 56% FPS drop from 1080p Ultra to 4K Ultra, so the GPU remains the primary differentiator. The RTX 3080’s 0.7% higher score would translate to less than 1 FPS difference in most scenarios, making it a negligible upgrade for this specific game.

The Verdict

This PC can run Downfall at 1080p and 1440p with playable performance across most settings, but 4K requires compromises. At 1920x1080, all four presets—Low, Medium, High, and Ultra—clear the 60 FPS threshold, with Ultra averaging 77 FPS. This is the resolution where the combo delivers its best experience, allowing players to use the highest visual quality without worrying about frame drops. At 2560x1440, High settings are the best playable option, averaging 88 FPS, while Ultra falls just short at 55 FPS. Players seeking maximum quality at 1440p will need to accept slightly lower frame rates or drop to High. At 3840x2160, only Low (82 FPS) and Medium (67 FPS) are playable, with Medium being the recommended choice for visual fidelity—though its minimum of 57 FPS indicates occasional dips below 60.

The verdict is clear: this system is a strong 1080p performer, a capable 1440p machine, and a limited 4K option. For players prioritizing frame rate, 1080p Ultra or 1440p High offers the best experience. For those with 4K displays, Medium settings provide a playable average, but the 57 FPS minimum suggests that highly demanding scenes may stutter. The 60 FPS threshold is consistently met at 1080p and 1440p High, making this a reliable choice for smooth gameplay at those resolutions.

CPU and GPU Roles

The data reveals how the Ryzen 9 9900X and Arc B580 share workload in Downfall, with the GPU taking on greater importance as resolution increases. At 1080p, the CPU’s strong multi-threaded performance (32,172 Cinebench R23 multi-core) ensures high frame rates even at Low settings (185 FPS), indicating the game is not CPU-bound at this resolution. The GPU’s role becomes more apparent in the settings scaling: from Low to Ultra, FPS drops by 108, showing that the Arc B580’s compute and memory resources directly influence visual quality.

At 1440p, the GPU’s dominance grows. The 77 FPS difference between Low (132 FPS) and Ultra (55 FPS) is steeper than at 1080p, suggesting that the Arc B580’s 13.67 TFLOPS FP32 throughput is increasingly strained. The CPU’s 12 cores and 24 threads remain sufficient, as evidenced by the 88 FPS High average, but the GPU’s 456 GB/s memory bandwidth becomes a limiting factor for Ultra settings. The 55 FPS Ultra result indicates the GPU cannot fully handle the increased pixel workload.

At 4K, the GPU is undeniably the bottleneck. The 34 FPS Ultra average is 56% lower than 1080p Ultra (77 FPS), while the CPU’s performance remains constant across resolutions. The Ryzen 9 9900X’s single-thread score of 2,253 in Cinebench R23 ensures it can feed the GPU at all resolutions, but the Arc B580’s 192-bit memory bus and 12 GB GDDR6 capacity struggle with 8.3 million pixels. The playable settings at 4K (Low and Medium) show that the GPU’s compute capacity is the deciding factor, not the CPU. In summary, the CPU is sufficient at all resolutions, while the GPU determines playability—more so at 1440p and 4K than at 1080p.
