Downfall

The AMD Ryzen 5 4600G paired with the NVIDIA GeForce RTX 5080 produces a striking performance profile in Downfall, one defined by a massive GPU advantage that is increasingly constrained by CPU headroom at lower resolutions. The data shows this combo ranks 164th out of 1,741 tested combinations, placing it in the top 9.4% of all systems, though the specific frame rates reveal that the Ryzen 5 4600G is often the limiting factor despite the RTX 5080’s raw power.

CPU Role — cores, clocks, and how they relate to this game's results

The Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, built on a 7nm process by TSMC. Its base clock is 3.70 GHz with a boost clock of 4.20 GHz, and it carries 8 MB of shared L3 cache alongside 64 KB of L1 and 512 KB of L2 per core. The processor’s benchmark scores show a clear split: single-thread performance is modest at 726 in 3dmark_single_thread and 1,919 in Cinebench R23 single-core, while multi-thread results are stronger, hitting 13,593 in Cinebench R23 multi-core and 15,992 in Passmark multithread.

In Downfall, the CPU’s 6 cores and 12 threads are sufficient to keep the system operational, but the data suggests they are not enough to fully feed the RTX 5080 at lower resolutions. At 1080p Low, the system reaches 295.3 FPS, while at 4K Low it drops to 185.4 FPS — a 37% reduction. The fact that 1080p Low does not approach the GPU’s theoretical ceiling, combined with the relatively weak single-thread score of 726, indicates that the processor’s per-core performance is the bottleneck in CPU-bound scenarios. The 4.20 GHz boost clock helps, but the architecture’s age limits how far the GPU can stretch at high frame rates.

The processor’s nearest rivals in overall benchmark average — the AMD Ryzen 3 PRO 5355GE (deltaPct 0), Intel Core i5-12450H (deltaPct 0.1), Intel Core i3-14100T (deltaPct -0.8), and Intel Core i3-13100F (deltaPct -1) — all sit within 1% of the 4600G’s average score of 17,489. This tells us the 4600G is firmly in a mid-range CPU tier. In Downfall, that tier is adequate for 4K gaming but leaves performance on the table at 1080p where the RTX 5080’s 56.28 TFLOPS FP32 compute cannot be fully utilized.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combo’s rank of 164 out of 1,741 tested combinations is a strong result, landing it in the top 9.4% of all systems tested. This ranking is driven almost entirely by the RTX 5080, which itself ranks in the 89th percentile among all GPUs with an average benchmark score of 59,188. The GPU’s nearest rivals — Intel Arc A570M (deltaPct 1.6), Intel Arc Pro A60 (deltaPct -1.9), Intel Arc A580 (deltaPct 2.5), and AMD Radeon Pro W5500X (deltaPct 2.6) — are all within 2.6% of the 5080’s average score, but the 5080’s 3DMark Steel Nomad DX12 score of 8,637 and Passmark G3D score of 36,565 demonstrate its high-end positioning.

The CPU, by contrast, sits at the 75th percentile among all CPUs, which is respectable but not elite. The gap between the GPU’s 89th percentile and the CPU’s 75th percentile is the defining characteristic of this pairing. In Downfall, the combo’s rank is likely higher than what the CPU alone could achieve, but lower than what the GPU alone would suggest. The data indicates that if the CPU were upgraded, the same GPU could push even higher frame rates at 1080p and 1440p, where the current scores are limited by the processor rather than the graphics card.

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

The measured frame rates show a clear pattern: as resolution increases, the performance drop is significant, but the relative drop between 1080p and 1440p is larger than between 1440p and 4K, which is a hallmark of CPU limitation at lower resolutions. At High settings, the system delivers 254.7 FPS at 1080p, drops to 205.4 FPS at 1440p (a 19.4% reduction), and then falls to 128.8 FPS at 4K (a 37.3% reduction from 1080p). The 1440p to 4K drop of 37.3% is actually smaller in percentage terms than the 1080p to 1440p drop of 19.4% when normalized per pixel, suggesting the GPU is taking over as the primary limiter at higher resolutions.

At Low settings, the pattern is even more pronounced: 295.3 FPS at 1080p, 262.1 FPS at 1440p (an 11.2% drop), and 185.4 FPS at 4K (a 37.2% drop from 1080p). The smaller drop from 1080p to 1440p at Low settings (11.2%) compared to High settings (19.4%) is counterintuitive if the GPU were the sole bottleneck — it indicates that at 1080p Low, the CPU is so heavily constrained that even reducing the GPU load does not meaningfully increase frame rates. The 4K Low result of 185.4 FPS vs 1080p Low at 295.3 FPS shows that at 4K, the GPU workload becomes significant enough to lower frame rates substantially, but the 4600G still cannot push beyond 295 FPS even at 1080p Low.

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

At 1920x1080, the system’s highest frame rate is 295.3 FPS at Low settings, followed by 273.1 FPS at Medium, 254.7 FPS at High, and 179.8 FPS at Ultra. The gap between Low and Ultra is 115.5 FPS, a 39.1% reduction, which is substantial but not as large as the gap seen at higher resolutions. The Medium-to-High difference is only 18.4 FPS, suggesting diminishing returns between those two presets.

At 2560x1440, Low produces 262.1 FPS, Medium 245.9 FPS, High 205.4 FPS, and Ultra 125 FPS. The Low-to-Medium gap is just 16.2 FPS, indicating that the CPU is still the primary limiter at these settings. The High-to-Ultra drop is 80.4 FPS, a 39.1% reduction, showing that Ultra settings place a heavy load on the GPU at this resolution.

At 3840x2160, Low delivers 185.4 FPS, Medium 153 FPS, High 128.8 FPS, and Ultra 76.5 FPS. The Ultra result is the lowest across all tested configurations, and the gap between High and Ultra at 4K is 52.3 FPS, a 40.6% reduction. The 4K Low result of 185.4 FPS is still well above 60 FPS, indicating that the RTX 5080’s 16 GB of GDDR7 memory and 960.0 GB/s bandwidth are more than sufficient for this game.

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

The RTX 5080 is a Blackwell 2.0 architecture GPU built on a 5nm process by TSMC, with 45,600 million transistors on a 378 mm² die. It features 10,752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores, with a base clock of 2295 MHz and a boost clock of 2617 MHz. The 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, and the GPU’s FP32 performance is 56.28 TFLOPS.

In Downfall, the GPU’s role becomes more apparent as resolution increases. At 4K Ultra, the system produces 76.5 FPS, which is exactly the kind of result that leverages the 5080’s full compute capability. The 4K High result of 128.8 FPS, 4K Medium of 153 FPS, and 4K Low of 185.4 FPS all demonstrate that the GPU has ample headroom at this resolution, with the CPU becoming less of a factor. The pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s are more than sufficient for this horror title, which does not appear to push the GPU to its limits even at Ultra settings.

The GPU’s 89th percentile ranking among all GPUs, with an average benchmark score of 59,188, places it well above the CPU’s 75th percentile. In Downfall, the data shows that the GPU is never the limiting factor at 1080p or 1440p, but at 4K, it becomes the primary determinant of frame rates. The 4K Ultra result of 76.5 FPS is the only configuration where the system drops below 100 FPS, and it still remains comfortably playable.

Settings Recommendations

For the best experience per the measured rows, the 1440p High preset at 205.4 FPS offers an optimal balance of visual quality and frame rate. At this setting, the system delivers smooth gameplay with a high refresh rate, and the 19.4% drop from 1080p High is acceptable given the resolution increase. If maximum frame rates are the priority, 1080p Low at 295.3 FPS is the fastest option, but the visual compromise is significant.

For 4K gaming, the High preset at 128.8 FPS is recommended over Ultra, as the 40.6% reduction from High to Ultra (128.8 to 76.5 FPS) is substantial and may not be worth the visual gains in a horror title where smoothness matters. The Medium preset at 4K (153 FPS) is also viable, offering a 18.8% improvement over High without the steep cost of Ultra. The data clearly shows that Ultra settings at any resolution impose a heavy penalty: 39.1% reduction from High at 1080p, 39.1% at 1440p, and 40.6% at 4K. Given the CPU’s limitations at lower resolutions, 1440p High is the sweet spot where the GPU’s capabilities are more fully utilized without the extreme cost of Ultra.
