Downfall

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data for Downfall with this AMD Ryzen 9 5950X and Radeon RX 6650 XT combo shows a very clear scaling pattern as resolution increases. At 1080p Low, the system delivers 199 FPS average. Moving to 1440p Low, that drops to 142 FPS — a 29% reduction. At 4K Low, the average falls to 88 FPS, which is 56% below the 1080p Low figure. This steep decline at lower settings is the classic signature of a GPU-bound scenario: as pixel count rises, the graphics card must work harder, and the CPU headroom becomes irrelevant.

The pattern holds across every settings tier. At High settings, 1080p produces 133 FPS, 1440p produces 95 FPS, and 4K produces 59 FPS. At Medium, the progression is 162 FPS → 116 FPS → 72 FPS. At Ultra, it is 83 FPS → 59 FPS → 37 FPS. In each case, the drop from 1080p to 1440p is roughly 25-30%, and the drop from 1440p to 4K is roughly 38-40%. This consistent scaling indicates that the Radeon RX 6650 XT is the limiting component at every resolution and settings combination tested — the CPU is not holding the system back, even at 1080p.

The fact that 4K Ultra yields just 37 FPS while 4K Low yields 88 FPS shows how sensitive this GPU is to the settings preset. The delta between Low and Ultra at the same resolution grows with pixel count: at 1080p, the difference is 116 FPS (199 vs 83); at 4K, the difference is 51 FPS (88 vs 37). This suggests that the GPU's shading units and memory bandwidth are the primary constraints, rather than any CPU-side bottleneck. The Ryzen 9 5950X, with its 16 cores and 32 threads, has ample computational headroom for a horror title like Downfall, which is not known for heavy multi-threaded workloads.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific pairing of AMD Ryzen 9 5950X and AMD Radeon RX 6650 XT ranks 2424 out of 3716 tested combos in Downfall. That places it in the lower-middle portion of the field — roughly the 35th percentile (calculated as 2424/3716). For a system built around a high-end 16-core CPU from 2020 and a mid-range GPU from 2022, this ranking reflects the fact that the RX 6650 XT is the performance ceiling. The CPU's impressive synthetic scores — Cinebench R23 multi-core at 26017, Geekbench multi-core at 15233, and a 91st percentile ranking among all CPUs — do not translate into a high combo rank because Downfall's frame rates are dictated by the GPU.

The GPU itself sits at the 65th percentile among all GPUs, with an average benchmark score of 19765. Its nearest rivals in the GPU benchmark list are the NVIDIA Tesla K40m (avg score 19885, delta -0.6%), the AMD FirePro D300 (avg score 19637, delta +0.7%), the AMD FirePro W7000 (avg score 19905, delta -0.7%), and the NVIDIA Quadro K5200 (avg score 19602, delta +0.8%). These deltas are all within 1% of the RX 6650 XT's score, meaning the GPU is essentially mid-pack in raw compute terms. The combo rank of 2424 suggests that many other CPU+GPU pairings in the database achieve higher frame rates in Downfall, likely because they pair a similar or weaker GPU with a less powerful CPU, or because they use a stronger GPU entirely.

The CPU's nearest rivals in the processor benchmark list are the Intel Core Ultra 5 235HX (avg score 52073, delta -0.2%), AMD EPYC 8124P (avg score 52121, delta -0.3%), Intel Core i9-13900F (avg score 51730, delta +0.4%), and Intel Core i7-14700 (avg score 52301, delta -0.7%). These deltas are all under 1%, confirming that the Ryzen 9 5950X is a top-tier performer in synthetic tests. Yet in Downfall, the combo's rank is not elevated by this CPU strength — the data shows a system that is GPU-limited in every measured scenario.

FAQ

Q: Is the AMD Ryzen 9 5950X bottlenecking the RX 6650 XT in Downfall?

A: No. The benchmark data shows consistent FPS scaling from 1080p to 4K across all settings, with no evidence of CPU limitation. At 1080p Low, the system reaches 199 FPS; if the CPU were the bottleneck, you would expect similar frame rates regardless of resolution, but the 4K Low result of 88 FPS proves the GPU is the limiting factor.

Q: What is the best resolution to play Downfall with this combo?

A: Based on the measured data, 1440p High at 95 FPS offers a strong balance between visual quality and smoothness. 4K High at 59 FPS is playable but right at the edge of 60 FPS, while 1080p High at 133 FPS leaves headroom for higher refresh rate displays.

Q: How does the RX 6650 XT compare to its closest GPU rivals in synthetic benchmarks?

A: The RX 6650 XT has an average benchmark score of 19765. It is 0.6% behind the NVIDIA Tesla K40m (19885), 0.7% ahead of the AMD FirePro D300 (19637), 0.7% behind the AMD FirePro W7000 (19905), and 0.8% ahead of the NVIDIA Quadro K5200 (19602). All four rivals are within 1% of its score.

Q: Can this system handle 4K Ultra settings in Downfall?

A: The measured average FPS at 4K Ultra is 37 FPS, which is below the standard 60 FPS target for smooth gameplay. It will be playable but with noticeable stutter in fast-paced horror sequences. Dropping to 4K High (59 FPS) or 4K Medium (72 FPS) is more practical.

Q: What is the CPU's synthetic multi-core performance relative to its nearest rivals?

A: The Ryzen 9 5950X scores 26017 in Cinebench R23 multi-core and 15233 in Geekbench multi-core. Its nearest rival, the Intel Core i7-14700, has an average benchmark score of 52301, which is 0.7% higher. The Intel Core i9-13900F is 0.4% lower, and the Intel Core Ultra 5 235HX is 0.2% lower.

Q: Does the 8 GB VRAM on the RX 6650 XT affect performance in Downfall?

A: The measured data shows that the GPU is the limiting factor at all resolutions, and the VRAM size is part of that constraint. At 4K Ultra, the average FPS drops to 37, which suggests the 8 GB frame buffer is sufficient but the GPU's compute resources are overwhelmed by the load.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

1080p (1920x1080):

• Low: 199 FPS average
• Medium: 162 FPS average, 138 FPS minimum, 187 FPS maximum
• High: 133 FPS average
• Ultra: 83 FPS average

1440p (2560x1440):

• Low: 142 FPS average
• Medium: 116 FPS average, 99 FPS minimum, 133 FPS maximum
• High: 95 FPS average
• Ultra: 59 FPS average

4K (3840x2160):

• Low: 88 FPS average
• Medium: 72 FPS average, 61 FPS minimum, 83 FPS maximum
• High: 59 FPS average
• Ultra: 37 FPS average

The Medium settings rows are the only ones with recorded minimum and maximum FPS values, providing insight into frame pacing. At 1080p Medium, the range from 138 to 187 FPS shows a 49 FPS spread; at 1440p Medium, the spread is 34 FPS (99 to 133); at 4K Medium, the spread narrows to 22 FPS (61 to 83). This tightening of the FPS range as resolution increases indicates that the GPU is becoming more consistently loaded, with less variation in frame render times — a common pattern when the GPU is fully saturated.

The gap between Low and Ultra settings is most pronounced at 1080p, where the difference is 116 FPS. At 1440p, that gap shrinks to 83 FPS; at 4K, it shrinks to 51 FPS. This diminishing difference suggests that at higher resolutions, the GPU's pixel throughput limit dominates, and the settings preset has relatively less impact on absolute frame rates.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6650 XT is built on the Navi 23 chip with RDNA 2.0 architecture, manufactured on a 7 nm process at TSMC. It has 8 GB of GDDR6 memory on a 128-bit bus, delivering 280.3 GB/s of memory bandwidth. The GPU's base clock is 2055 MHz, with a game clock of 2410 MHz and a boost clock of 2635 MHz. In the context of Downfall, a horror title from 2016, these specifications are more than sufficient for the game's era, but the measured frame rates show that the GPU's 2048 shading units and 64 ROPs are the binding constraint at higher resolutions.

The boost clock of 2635 MHz is the ceiling the GPU can reach under load, and the measured FPS data suggests the card is running near that limit in most scenarios. The 8 GB VRAM is not likely the primary bottleneck in this game — the fact that 4K Low (88 FPS) is over twice as fast as 4K Ultra (37 FPS) points to shading and texture throughput rather than memory capacity. The 280.3 GB/s bandwidth is adequate for 4K at lower settings, but the Ultra preset likely increases texture sampling and post-processing loads that tax the 128 TMUs.

The GPU's synthetic benchmarks reinforce this interpretation. Its Passmark G3D score of 17166 and 3DMark Steel Nomad DX12 score of 1859 place it at the 65th percentile among all GPUs. The nearest rivals in its benchmark class are all professional or older workstation cards (Tesla K40m, FirePro D300, FirePro W7000, Quadro K5200), which suggests the RX 6650 XT is positioned as a mainstream gaming card that competes with much older pro hardware in raw compute but has modern features like DirectX 12 Ultimate support. In Downfall, the GPU's 10.79 TFLOPS of FP32 performance is what drives the measured frame rates, and the scaling from 199 FPS at 1080p Low to 37 FPS at 4K Ultra is consistent with a card that has fixed compute resources being spread across increasing pixel counts.

Settings Recommendations — which preset gives the best experience per the measured rows

For a smooth 60+ FPS experience in Downfall, the data points to 1440p High as the sweet spot. At 95 FPS average, this preset provides a comfortable margin above 60 FPS, and the visual quality of High settings is sufficient for a horror title where atmosphere matters. If you have a 144 Hz monitor, 1080p Medium at 162 FPS is the strongest option — it is the highest measured frame rate above 144 FPS, and the minimum of 138 FPS ensures you stay above the refresh rate threshold.

For 4K gaming, the choices are more constrained. 4K Medium at 72 FPS is the only 4K preset that clears 60 FPS with a minimum of 61 FPS, making it the recommended choice for 4K displays. 4K High at 59 FPS is borderline — it will feel smooth in slow-paced horror exploration but may dip in action sequences. 4K Ultra at 37 FPS is not recommended unless you prioritize visual fidelity over playability and can tolerate sub-60 FPS frame rates.

At 1080p, the Ultra preset at 83 FPS is a viable option for players who want maximum visual quality without dropping below 60 FPS. The 1080p High preset at 133 FPS is ideal for high-refresh-rate 144 Hz monitors, offering a 50 FPS headroom above the refresh threshold. The 1080p Low preset at 199 FPS is only useful for competitive play or if you want to maximize frame rate for a 240 Hz display, but the visual downgrade is significant in a horror game where lighting and shadows contribute to the experience.

The Medium preset is the only one with measured minimum FPS data across all resolutions, and those minimums (138 at 1080p, 99 at 1440p, 61 at 4K) suggest that Medium provides the most consistent frame pacing. If you experience stutter in Downfall, the Medium preset at your target resolution is the safer choice, as the minimum FPS figures indicate less variance than the other presets (which lack min/max data but likely have wider swings based on the average-to-minimum patterns at Medium).
