GPU Role

The NVIDIA GeForce RTX 5080 is the primary driver of frame rates in Downfall, and its specifications explain the measured performance. The GPU operates with a base clock of 2295 MHz and a boost clock of 2617 MHz, with memory running at 1875 MHz or 30 Gbps effective. These clocks feed 10752 shading units, 336 texture mapping units, and 112 raster output pipelines.

The 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth. This memory subsystem is critical for the 4K results, where the Ultra preset demands substantial texture data. The measured 77 FPS at 4K Ultra demonstrates that the memory bandwidth is sufficient, but the frame rate drop from Medium's 151 FPS indicates that raw compute throughput becomes the limiting factor at the highest settings.

The RTX 5080's 84 ray tracing cores and 336 tensor cores are present in the architecture, though Downfall's 2016 release date means the game does not utilize these modern features. The GPU's 56.28 TFLOPS FP32 performance is the relevant metric for this title's traditional rasterization workload. The pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s ensure that the GPU can handle the game's horror-themed environments without fill rate limitations.

The GPU's benchmark scores contextualize its performance. In 3DMark Steel Nomad DX12, it scores 8637, while Geekbench Vulkan shows 255450 and OpenCL shows 235901. Passmark G3D gives 36565, placing the GPU in the 87th percentile of all graphics cards. The nearest rival, the AMD Radeon 8060S, has an average benchmark score of 55757 compared to the RTX 5080's 56083, a delta of 0.6%. The AMD Radeon RX 9070 GRE scores 57367, which is 2.2% higher, indicating the RTX 5080 sits in a competitive mid-to-high tier.

The GPU's 360 W TDP and suggested 750 W PSU indicate substantial power requirements, but the measured frame rates justify this consumption. The dual-slot cooler and 304 mm length are standard for this performance class. The RTX 5080's 5 nm process node from TSMC houses 45,600 million transistors on a 378 mm² die.

How This Combo Ranks

The AMD Ryzen 9 9900X3D with NVIDIA GeForce RTX 5080 achieves a combo rank of 165 out of 2928 tested combinations in Downfall. This places the system in the 94th percentile of all configurations, meaning only 5.6% of tested combos deliver higher frame rates. Given the game's 2016 release date, this ranking reflects the substantial headroom that modern hardware provides for older titles.

The CPU component of this ranking is supported by the 9900X3D's benchmark scores. The processor achieves 47737 in Cinebench R23 multicore and 6739 in single-core, with a Geekbench multicore score of 22884. Its average benchmark score of 54762 places it in the 91st percentile of all CPUs. The nearest rival, the Intel Core Ultra 5 245KF, scores 55093, which is 0.6% higher, while the Intel Core Ultra 5 245K scores 54053, 1.3% lower. This puts the 9900X3D in a tightly contested mid-range CPU segment.

The GPU's contribution is equally significant. With an average benchmark score of 56083 and an 87th percentile ranking, the RTX 5080 performs within 0.7% of the AMD Radeon RX 6750 GRE 12 GB, which scores 55698. The RTX 5080's predecessor in performance terms, the AMD Radeon RX 9070 GRE, leads by 2.2% with a score of 57367. These narrow deltas show that the RTX 5080 is competitive but not dominant in raw compute.

The combination of a 91st percentile CPU with an 87th percentile GPU produces a 94th percentile gaming result. This synergy indicates that neither component significantly bottlenecks the other in Downfall. The CPU's 12 cores and 24 threads at 4.40 GHz base and 5.50 GHz boost provide ample instruction throughput, while the GPU's 16 GB memory capacity prevents any texture swapping issues at 4K resolution.

The ranking also reflects the system's ability to maintain high minimum frame rates. At 2560x1440 Medium, the 206 FPS minimum is particularly strong, suggesting that the 128 MB L3 cache on the CPU helps maintain consistent frame delivery during sudden scene changes typical of horror games. This cache size, combined with the GPU's 960.0 GB/s bandwidth, creates a data pipeline that rarely stalls.

Resolution Scaling

The frame rate scaling from 1920x1080 to 3840x2160 reveals how the system's components share the workload. At Medium settings, the progression is 339 FPS at 1080p, 242 FPS at 1440p, and 151 FPS at 4K. This represents a 29% drop from 1080p to 1440p, followed by a 38% drop from 1440p to 4K. The pixel count increases by 78% from 1080p to 1440p, and by 125% from 1440p to 4K, meaning the frame rate drops are proportionally smaller than the pixel increases.

This pattern indicates a GPU-bound scenario at higher resolutions. The RTX 5080's 56.28 TFLOPS FP32 performance is the limiting factor as resolution increases, while the CPU's 128 MB L3 cache and 24 threads remain underutilized. At 1080p, the 414 FPS Low preset result suggests the CPU can push the GPU to its maximum output, but the GPU becomes the constraint as pixel count grows.

The Low preset scaling shows a similar trend: 414 FPS at 1080p, 296 FPS at 1440p, and 184 FPS at 4K. The 4K result is 44% of the 1080p figure, while the pixel count is 400% larger. This disproportionate scaling confirms that the GPU's fill rate and shading capacity, rather than memory bandwidth, determine the upper limits.

The Ultra preset exhibits the steepest scaling curve: 174 FPS at 1080p, 124 FPS at 1440p, and 77 FPS at 4K. The 4K result is 44% of the 1080p result, identical to the Low preset's ratio. This consistency across presets suggests that the GT/s rates of the GPU—879.3 GTexel/s texture rate and 293.1 GPixel/s pixel rate—are the binding constraints, as these values scale directly with resolution.

The CPU's role in resolution scaling is minimal. The 9900X3D's single-thread score of 6739 in Cinebench R23 and 3041 in Geekbench provides enough headroom that even at 1080p Low, the 414 FPS result does not hit a CPU ceiling. The 3DMark 16-thread score of 12490 and max-thread score of 13795 confirm that multi-threaded performance is not a limiting factor in this game.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates across all presets. The Low preset leads with 414 FPS average, followed by Medium at 339 FPS with a minimum of 288 FPS and maximum of 390 FPS. The High preset delivers 278 FPS average, while the Ultra preset produces 174 FPS average. No minimum or maximum values are recorded for Low, High, or Ultra at this resolution, but the Medium preset's 288 FPS minimum ensures no dips below 240 Hz.

At 2560x1440, the performance hierarchy remains consistent. Low preset reaches 296 FPS average, Medium delivers 242 FPS with a 206 FPS minimum and 278 FPS maximum, High produces 198 FPS, and Ultra achieves 124 FPS. The Medium preset's 206 FPS minimum is particularly strong, staying above the 200 FPS threshold that high-refresh-rate gamers target.

At 3840x2160, the system shows its first signs of stress. Low preset manages 184 FPS average, Medium delivers 151 FPS with a 128 FPS minimum and 173 FPS maximum, High produces 123 FPS, and Ultra drops to 77 FPS. The Medium preset's 128 FPS minimum is the key figure here, as it remains above 120 FPS, making this the lowest resolution-settings combination that can sustain a 120 Hz 4K display without stutter.

The Ultra preset at 4K, with its 77 FPS average, is the only measured configuration that falls below the 100 FPS mark. This result, while playable on 60 Hz displays, represents a significant drop from the 124 FPS achieved at 1440p Ultra. The 38% performance loss from 1440p to 4K at Ultra settings mirrors the pixel count increase, confirming that the RTX 5080's shading units are fully utilized at this configuration.

Across all resolutions, the Medium preset offers the most complete dataset with both minimum and maximum frame rates recorded. The consistency of the minimum values—288 FPS at 1080p, 206 FPS at 1440p, and 128 FPS at 4K—shows a predictable degradation pattern. Each resolution step reduces the minimum by roughly 40%, which aligns with the GPU's pixel throughput capabilities. The 16 GB GDDR7 memory never appears as a limiting factor, as even the 4K Ultra result shows no signs of texture thrashing or memory-related frame drops.
