# Downfall with AMD Ryzen 9 8945HX + NVIDIA GeForce RTX 5070 Ti

The AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 5070 Ti delivers a commanding performance profile in Downfall, a 2016 horror title that remains demanding at high resolutions. The measured data shows this combination ranks 1041st out of 2928 tested CPU-GPU combos for this game, placing it in the top 36% of all configurations. The RTX 5070 Ti's benchmark percentile of 86 versus all GPUs indicates strong overall capability, while the Ryzen 9 8945HX sits at the 95th percentile against all CPUs. In practical terms, this system achieves smooth 4K gameplay at High settings and exceeds 200 FPS at 1080p on Medium, demonstrating that the GPU is the primary performance driver across most of the tested spectrum.

Resolution Scaling

The FPS progression from 1080p to 4K reveals a predictable but steep performance curve that highlights the GPU-bound nature of Downfall at higher resolutions. At Low settings, the system delivers 263 FPS at 1080p, drops to 188 FPS at 1440p (a 28.5% reduction), and falls further to 117 FPS at 4K (a 37.8% reduction from 1440p). This scaling pattern indicates that the RTX 5070 Ti's compute resources are being increasingly taxed as pixel count rises, with the 4K Low result still maintaining a highly playable frame rate.

Moving to Medium settings, the same resolution progression shows 215 FPS at 1080p, 154 FPS at 1440p (a 28.4% drop), and 96 FPS at 4K (a 37.7% drop from 1440p). The consistency of these percentage drops across Low and Medium presets suggests that the game's rendering workload scales uniformly with resolution, and that neither the CPU nor GPU introduces bottlenecks that would distort this relationship. The 4K Medium result of 96 FPS with a minimum of 81 FPS and maximum of 110 FPS indicates that the hardware maintains stable frame delivery even under increased pixel pressure.

At High settings, the scaling becomes even more pronounced. The system achieves 176 FPS at 1080p, 126 FPS at 1440p (a 28.4% reduction), and 78 FPS at 4K (a 38.1% reduction from 1440p). The Ultra preset reveals the most dramatic resolution sensitivity, with 110 FPS at 1080p falling to 79 FPS at 1440p (a 28.2% drop) and then to 49 FPS at 4K (a 38.0% drop from 1440p). This consistent ~28% penalty for stepping from 1080p to 1440p and ~38% penalty for stepping from 1440p to 4K across all settings indicates that the RTX 5070 Ti's 16 GB of GDDR7 memory and 256-bit bus are sufficient, but the GPU's raw shading throughput becomes the limiting factor at 4K Ultra.

The data suggests that 4K Ultra at 49 FPS represents the boundary of playable performance for this combination, while 4K High at 78 FPS offers a more comfortable margin. The resolution scaling analysis points to the GPU as the limiting component at 4K, as the CPU's 16 cores and 32 threads are unlikely to be saturated by a 2016 horror title even at lower resolutions.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is the undisputed performance anchor in this configuration, and its specifications directly explain the measured FPS results. The GPU features 8960 shading units, 280 texture mapping units, and 96 raster output pipelines, with base and boost clocks of 2295 MHz and 2452 MHz respectively. These specifications translate to a pixel rate of 235.4 GPixel/s and a texture rate of 686.6 GTexel/s, which are substantial figures for handling Downfall's horror-themed environments that likely feature detailed textures and lighting effects.

The 16 GB of GDDR7 memory on a 256-bit bus provides 896.0 GB/s of bandwidth, which proves adequate even at 4K resolutions where texture data demands are highest. The measured FPS at 4K Medium (96 FPS) versus 4K High (78 FPS) shows a 23.1% performance cost for the step up in quality, which is a moderate penalty that reflects increased shading and texture work rather than memory bandwidth limitations. The Ultra preset at 4K drops to 49 FPS, a 37.2% reduction from High, indicating that the most demanding settings push the GPU's compute capacity to its limits.

The GPU's benchmark scores reinforce its position in the performance hierarchy. The 3DMark Steel Nomad DX12 score of 6604 and Geekbench Vulkan score of 225122 demonstrate strong modern API performance, while the Passmark G3D score of 32974 places it at the 86th percentile versus all GPUs. The nearest rival comparison shows the RTX 5070 Ti trailing the AMD Radeon RX 6900 XT by 2% in average benchmark score, but leading the RX 6800 XT by 3.1%. This competitive positioning explains why the GPU can deliver 176 FPS at 1080p High but struggles to maintain 50 FPS at 4K Ultra — the hardware is capable but not unlimited.

The GPU's FP32 compute of 43.94 TFLOPS and FP16 performance at a 1:1 ratio of 43.94 TFLOPS indicate balanced compute capabilities that benefit both traditional rasterization and any potential ray-traced effects in Downfall. The 70 RT cores and 280 tensor cores provide additional headroom for advanced rendering features, though the 2016 game's engine likely relies primarily on conventional shading. The 300 W TDP and 700 W suggested PSU requirement are notable power considerations, but they enable the sustained clock behavior needed for consistent frame delivery across extended gaming sessions.

Settings Recommendations

The measured FPS data provides clear guidance for optimizing the Downfall experience with this hardware. At 1080p, all settings presets deliver playable frame rates, but the Ultra preset at 110 FPS versus High at 176 FPS represents a 37.5% performance cost that may not justify the visual improvements for competitive or fast-paced play. The Medium preset at 215 FPS offers the best balance for high-refresh-rate monitors, with the measured minimum of 183 FPS ensuring no drops below 144 Hz refresh rates.

At 1440p, the Medium preset delivers 154 FPS with a minimum of 130 FPS, making it the recommended choice for smooth gameplay on 144 Hz displays. High settings at 126 FPS remain viable, but the margin above 60 FPS is thinner. The Ultra preset at 79 FPS is playable but sacrifices the high-refresh experience, making it suitable only for players who prioritize visual fidelity over frame rate. Low settings at 188 FPS provide maximum performance headroom but likely compromise the atmospheric horror experience that benefits from detailed shadows and textures.

For 4K gaming, the High preset at 78 FPS is the clear sweet spot. This delivers a smooth experience on 60 Hz displays with room to spare, and the visual quality remains high enough to appreciate the game's horror aesthetics. Medium at 96 FPS offers additional headroom for variable refresh rate displays, while Ultra at 49 FPS is borderline and may result in noticeable stutter during intense scenes. Low at 117 FPS is playable but undermines the visual immersion that horror games rely on.

The data indicates that the RTX 5070 Ti's 16 GB VRAM is not a limiting factor at any resolution or settings combination tested, as even the most demanding 4K Ultra preset completed without memory-related performance collapses. The recommended presets — Medium at 1080p, Medium at 1440p, and High at 4K — all provide frame rates that comfortably exceed 60 FPS while maintaining visual quality appropriate for a horror title where atmosphere matters.

This grouping indicates that the CPU's performance is competitive with the best mobile and desktop processors, making it unlikely to limit frame rates in Downfall at any of the tested resolutions.

In the measured FPS data, the CPU's influence is most apparent at 1080p Low settings where the GPU has the least work to do. The 263 FPS result at 1080p Low demonstrates that the CPU can feed the GPU with sufficient draw calls and game logic updates to sustain very high frame rates. The 32 threads provide ample capacity for any background tasks, while the 5.40 GHz boost clock ensures responsive single-threaded performance for the game's primary simulation thread. The DDR5 memory support with 83.2 GB/s bandwidth and dual-channel configuration further reduces any potential data delivery bottlenecks.

Measured FPS Breakdown

The complete measured FPS dataset reveals consistent performance patterns across all resolution and settings combinations:

1920x1080 (1080p):

• Low: 263 FPS average
• Medium: 215 FPS average, with a minimum of 183 FPS and maximum of 247 FPS
• High: 176 FPS average
• Ultra: 110 FPS average

2560x1440 (1440p):

• Low: 188 FPS average
• Medium: 154 FPS average, with a minimum of 130 FPS and maximum of 177 FPS
• High: 126 FPS average
• Ultra: 79 FPS average

3840x2160 (4K):

• Low: 117 FPS average
• Medium: 96 FPS average, with a minimum of 81 FPS and maximum of 110 FPS
• High: 78 FPS average
• Ultra: 49 FPS average

The Medium preset at each resolution includes minimum and maximum FPS measurements, providing insight into frame time consistency. At 1080p Medium, the range from 183 to 247 FPS shows a spread of 64 FPS, indicating some variation but maintaining a minimum well above 144 Hz. At 1440p Medium, the 130 to 177 FPS range represents a 47 FPS spread, with the minimum still exceeding 120 Hz. At 4K Medium, the 81 to 110 FPS range shows an 29 FPS spread, and the minimum of 81 FPS remains comfortably above 60 Hz.

The performance deltas between settings presets are consistent across resolutions. Moving from Low to Medium costs approximately 18-19% performance at each resolution (263 to 215 at 1080p, 188 to 154 at 1440p, 117 to 96 at 4K). The step from Medium to High costs approximately 18-19% as well (215 to 176, 154 to 126, 96 to 78). However, the step from High to Ultra is more expensive at approximately 37-38% (176 to 110, 126 to 79, 78 to 49), indicating that the Ultra preset includes disproportionately demanding effects.

The resolution scaling from 1080p to 1440p consistently costs approximately 28% performance across all settings, while the step from 1440p to 4K costs approximately 38% performance. This increasing penalty with resolution suggests that the GPU's fill rate and shading capacity become progressively more strained as pixel count quadruples from 1080p to 4K. The 4K Ultra result of 49 FPS represents the only configuration that falls below 60 FPS, indicating that this combination is capable of handling all but the most demanding settings at the highest resolution.
