Downfall

# Downfall with AMD Ryzen 9 9900X + AMD Radeon RX 6650 XT

This combination of the AMD Ryzen 9 9900X and AMD Radeon RX 6650 XT places at rank 2424 out of 3716 tested combos in Downfall, putting it in the lower-middle portion of the field. The CPU is a top-tier part — its 92nd percentile ranking among all CPUs and an average benchmark score of 57498 — while the GPU sits at just the 65th percentile among all GPUs with an average score of 19765. That imbalance is the defining characteristic of this pairing: the processor is dramatically more capable than the graphics card, and the measured frame rates across all resolutions and settings reflect that the RX 6650 XT is the primary constraint on performance in this horror title.

How This Combo Ranks

The combo rank of 2424 out of 3716 represents the 34.8th percentile of tested configurations in Downfall. This is a modest result, and the data suggests why: the GPU's 65th percentile standing among all GPUs is the limiting factor. In terms of raw synthetic benchmarks, the RX 6650 XT's nearest rivals are the NVIDIA Tesla K40m (deltaPct -0.6), AMD FirePro D300 (deltaPct 0.7), AMD FirePro W7000 (deltaPct -0.7), and NVIDIA Quadro K5200 (deltaPct 0.8). All of these are within 0.8% of the RX 6650 XT's average score of 19765, indicating that this GPU is closely clustered with a group of professional and older workstation cards in general compute performance.

The CPU tells a different story. The Ryzen 9 9900X's nearest rivals are the AMD EPYC 9015 (deltaPct -0.1), AMD EPYC 7313 (deltaPct 0.2), Intel Core i9-14900 (deltaPct -1.1), and Intel Xeon Platinum 8260M (deltaPct -1.4). The 9900X's average benchmark score of 57498 places it within 1.4% of these server and high-end desktop parts, which is remarkable for a 12-core desktop processor. The deltaPct values here are small — the 9900X is essentially tied with the EPYC 9015 and trails the Intel Core i9-14900 by just 1.1%. This CPU is a heavyweight, but in Downfall, that heavyweight status doesn't translate into elite frame rates because the GPU cannot keep pace.

The measured FPS data confirms the bottleneck pattern. At 1080p Low, the combo produces 199 FPS, but that drops to 83 FPS at 1080p Ultra. At 4K, the range is 37 FPS (Ultra) to 88 FPS (Low). These numbers place the combo firmly in mid-pack territory, consistent with its 2424 rank. The percentile gap between CPU (92nd) and GPU (65th) is the single most informative statistic for understanding this pairing's position in the overall rankings.

Settings Recommendations

The measured data across all three resolutions and four settings levels provides a clear picture of which preset offers the best experience. At 1080p, the Low preset delivers 199 FPS, Medium 162 FPS, High 133 FPS, and Ultra 83 FPS. The Medium preset, with a minimum of 138 FPS and maximum of 187 FPS, offers the most balanced experience — it maintains well above 120 FPS on average while providing a substantial visual uplift over Low. High at 133 FPS is also viable, but the jump from Medium to High costs 29 FPS, which is a significant trade-off for what is typically a modest visual improvement in horror titles.

At 1440p, the pattern shifts. Low produces 142 FPS, Medium 116 FPS (minimum 99, maximum 133), High 95 FPS, and Ultra 59 FPS. The Medium preset again emerges as the sweet spot, with an average of 116 FPS and a minimum of 99 FPS that keeps the experience smooth. High at 95 FPS is acceptable but starts to approach the threshold where frame drops become noticeable. Ultra at 59 FPS is borderline unplayable for a genre that benefits from responsive camera movement.

At 4K, the choices are more constrained. Low gives 88 FPS, Medium 72 FPS (minimum 61, maximum 83), High 59 FPS, and Ultra 37 FPS. The Medium preset is the clear recommendation here — it is the only 4K setting that stays above 60 FPS on average while providing a reasonable minimum of 61 FPS. High at 59 FPS is technically playable but sits right at the edge, and Ultra at 37 FPS is not a viable experience. For users prioritizing frame rate at 4K, Low at 88 FPS is the alternative, but Medium offers substantially better visuals for a 16 FPS cost.

Resolution Scaling

The FPS drop from 1080p to 4K across settings reveals the GPU-bound nature of this configuration. At Low settings, the progression is 199 FPS (1080p) to 142 FPS (1440p) to 88 FPS (4K) — a 55.8% reduction from 1080p to 4K. At Medium, the numbers are 162 to 116 to 72, a 55.6% reduction. At High, 133 to 95 to 59, a 55.6% reduction. At Ultra, 83 to 59 to 37, a 55.4% reduction.

The consistency of these percentages — all falling between 55.4% and 55.8% — is a textbook signature of a GPU-bound scenario. If the CPU were the limiting factor, the scaling from 1080p to 4K would show a much smaller FPS drop at lower resolutions, where the CPU is more likely to be the constraint. Instead, the uniform ~55% reduction across all settings indicates that the RX 6650 XT's rendering throughput is the dominant factor at every resolution.

The 1440p to 4K transition is particularly telling. At Low, going from 142 to 88 FPS is a 38.0% drop; at Medium, 116 to 72 is a 37.9% drop; at High, 95 to 59 is a 37.9% drop; at Ultra, 59 to 37 is a 37.3% drop. The pixel count increase from 1440p to 4K is 2.25x, but the FPS drops by less than 40%, which suggests that the GPU has some headroom in its memory bandwidth and cache hierarchy. Still, the overall pattern is clear: this is a GPU-limited configuration, and the Ryzen 9 9900X's substantial compute resources — 12 cores, 24 threads, and a 5.60 GHz boost clock — are not being fully utilized in this game.

Measured FPS Breakdown

At 1920x1080, the full settings range is available. Low produces an average of 199 FPS. Medium averages 162 FPS with a minimum of 138 and maximum of 187. High averages 133 FPS. Ultra averages 83 FPS. The spread from Low to Ultra is 116 FPS, which is a 58.3% reduction — a large drop that indicates the Ultra preset imposes significant rendering costs on this GPU.

At 2560x1440, the numbers scale down proportionally. Low averages 142 FPS. Medium averages 116 FPS with a minimum of 99 and maximum of 133. High averages 95 FPS. Ultra averages 59 FPS. The 83 FPS spread from Low to Ultra represents a 58.5% reduction, nearly identical to the 1080p percentage, reinforcing the GPU-bound analysis.

At 3840x2160, the performance envelope tightens. Low averages 88 FPS. Medium averages 72 FPS with a minimum of 61 and maximum of 83. High averages 59 FPS. Ultra averages 37 FPS. The 51 FPS spread from Low to Ultra is a 58.0% reduction. Notably, the minimum FPS at 4K Medium (61) is exactly at the threshold of 60 FPS, meaning any scene complexity spike could push it below playable levels.

The Medium presets across all resolutions are the only settings with measured minimum and maximum values. At 1080p, the min-max range is 138-187 (a 49 FPS spread); at 1440p, it is 99-133 (34 FPS); at 4K, it is 61-83 (22 FPS). The narrowing range at higher resolutions suggests that the GPU is becoming more consistently saturated, with less variance in frame times as the render load increases.

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 on a 237 mm² die. It features 2048 shading units, 128 texture mapping units, and 64 render output units, along with 32 ray tracing cores. The GPU's FP32 compute is rated at 10.79 TFLOPS, with FP16 at 21.59 TFLOPS (2:1). These specifications place it as a mid-range part, and its 65th percentile ranking among all GPUs confirms that positioning.

The memory subsystem consists of 8 GB of GDDR6 on a 128-bit bus, yielding 280.3 GB/s of bandwidth. The memory clock is 2190 MHz (17.5 Gbps effective). The 8 GB capacity is sufficient for Downfall at 1080p and 1440p, but at 4K, the combination of higher resolution textures and the game's horror-themed environments — which often feature complex lighting and shadow effects — could pressure the memory capacity. The measured 4K performance, ranging from 37 to 88 FPS across settings, suggests that the GPU is not running out of memory outright but is instead limited by raw compute and fill rate.

The clocks are notable: a base of 2055 MHz, a game clock of 2410 MHz, and a boost of 2635 MHz. These are high frequencies for a 7 nm part, and the boost behavior is consistent with the measured FPS scaling. The pixel rate of 168.6 GPixel/s and texture rate of 337.3 GTexel/s are the key specs for understanding Downfall's performance, as horror games frequently rely on high-resolution textures and volumetric effects. The GPU's DirectX 12 Ultimate (12_2) support and Vulkan 1.4 API compatibility ensure modern rendering paths are available.

The RX 6650 XT's nearest rivals in synthetic benchmarks are all professional or older cards — the NVIDIA Tesla K40m, AMD FirePro D300, AMD FirePro W7000, and NVIDIA Quadro K5200 — all within 0.8% of its average score. This clustering is unusual for a consumer gaming GPU and suggests that the RX 6650 XT's gaming-specific optimizations are not fully captured by general compute benchmarks. In Downfall specifically, the measured FPS indicates the GPU is performing as expected for its class: capable at 1080p and 1440p with medium settings, but struggling at 4K Ultra.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture (Granite Ridge codename), fabricated on a 4 nm process at TSMC. It has a base clock of 4.40 GHz and a boost clock of 5.60 GHz, with a TDP of 120 W. The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. Memory support is DDR5 with dual-channel configuration and 89.6 GB/s of bandwidth, and the CPU connects via PCIe Gen 5 with 24 lanes. It was released in August 2024 with a launch MSRP of $499.

In synthetic benchmarks, the 9900X delivers strong results: Cinebench R23 multicore scores 32172 and singlecore 2253; Geekbench multicore is 22174 and singlecore is 3010; Passmark multithread is 54643 and single thread is 4672. The 3DMark scores show scaling from 1286 (single thread) to 13929 (max threads), demonstrating excellent multi-threaded performance. The CPU's 92nd percentile ranking and its nearest rivals — the AMD EPYC 9015, AMD EPYC 7313, Intel Core i9-14900, and Intel Xeon Platinum 8260M — all within 1.4% of its average score, confirm that this is a top-tier desktop processor.

However, in Downfall, the CPU's capabilities are largely untapped. The measured FPS scaling patterns — with nearly identical percentage drops from 1080p to 4K across all settings — indicate that the game is not CPU-bound at any resolution. Even at 1080p Low, where the CPU would be most likely to become a constraint, the combo produces 199 FPS, which is well below the 9900X's theoretical ceiling. The 12 cores and 24 threads are far more than Downfall requires, and the 5.60 GHz boost clock provides ample single-thread performance for game logic and physics.

The contrast between the CPU's 92nd percentile and the GPU's 65th percentile is stark. This is a configuration where the processor is overqualified for the graphics card paired with it. In a more GPU-balanced system, the 9900X would likely enable significantly higher frame rates in Downfall, but with the RX 6650 XT, the CPU sits idle while the GPU works at full capacity. The data shows that upgrading the GPU would yield far larger performance gains in this game than any CPU change.
