Downfall

The AMD Ryzen 5 5600X paired with the AMD Radeon RX 6750 XT delivers a robust performance profile in Downfall, a 2016 horror title. The measured data shows a combination that scales predictably across resolutions and settings, with the 1080p results suggesting a system capable of very high frame rates, while the 4K Ultra preset presents the only significant challenge to maintaining smooth gameplay.

Resolution Scaling

The performance drop from 1080p to 4K is substantial and reveals the shifting balance between CPU and GPU workload. At 1080p with Low settings, the system achieves an average of 242 FPS. Moving to 1440p Low drops this to 172 FPS, a reduction of 70 FPS. At 4K Low, the average falls further to 106.2 FPS. This steep decline indicates that at lower resolutions and settings, the frame rate is heavily influenced by the CPU's ability to feed the GPU, though the Radeon RX 6750 XT continues to scale output as resolution increases.

The scaling pattern changes when settings are raised. At High settings, the frame rate goes from 160.4 FPS at 1080p, to 116 FPS at 1440p, and finally to 72.2 FPS at 4K. The percentage drop from 1080p to 4K is smaller at High settings compared to Low, suggesting that the GPU becomes the primary limiting factor as graphical complexity increases. The Ultra preset shows the most dramatic scaling, with 103.5 FPS at 1080p, 74.3 FPS at 1440p, and just 45.4 FPS at 4K. This 58 FPS difference between 1080p and 4K Ultra points to a GPU that is fully engaged by the highest fidelity settings, leaving little overhead for resolution increases.

Benchmark results indicate that the sweet spot for this combination is 1440p, where the GPU can still push high frame rates across most settings. The data suggests that at 1080p, the CPU's 6 cores and 12 threads are sufficient to prevent bottlenecking, allowing the GPU to work near its potential. At 4K, the GPU's 12 GB of GDDR6 memory and 432.0 GB/s bandwidth are taxed heavily, particularly with the Ultra preset, which cuts performance nearly in half compared to 1080p.

Q: Does the GPU’s benchmark score align with its in-game performance?

A: The GPU has a Passmark G3D score of 20700 and sits in the 79th percentile of all GPUs. This aligns with the in-game results, which show it handling 1440p High at 116 FPS and 4K High at 72.2 FPS, indicating a solid mid-to-high-range performer.

CPU Role

The AMD Ryzen 5 5600X is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer. It operates with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. In Downfall, the CPU's influence is most apparent at lower resolutions and settings where frame rates are exceptionally high. The 1080p Low result of 242 FPS demonstrates that the processor can handle the game's logic and draw calls without creating a significant bottleneck.

The CPU's cache hierarchy includes 32 MB of L3 cache, which helps with game data access. Its benchmark scores reflect strong multi-threaded capabilities, with a Cinebench R23 multi-core score of 18578 and a single-core score of 2622. The 3dMark single-thread score of 917 and the Passmark single-thread score of 3364 both support the CPU's ability to drive high frame rates in less GPU-intensive scenarios.

Compared to its nearest rivals, the Ryzen 5 5600X is closely matched. It trails the AMD Ryzen 5 5600GT by 0.3% and the Intel Core i7-10700 by 0.3% in average benchmark score. It also sits 0.5% behind the Intel Core i5-12490F. These small deltas mean the CPU's performance in Downfall is representative of its class. The 65 W TDP and 7 nm process node from TSMC contribute to efficient operation, though the game results show that at 1080p Low, the CPU is still capable of pushing frame rates beyond 240 FPS, indicating headroom for even more powerful GPUs.

Measured FPS Breakdown

At 1920x1080, the system delivers its best performance. The Low preset averages 242 FPS, which is the highest recorded result. Medium settings produce 194.8 FPS, while High drops to 160.4 FPS. The Ultra preset at 1080p averages 103.5 FPS, which is still very playable and suggests that the CPU is not holding back the GPU at this resolution.

Moving to 2560x1440, the frame rates remain high but show the GPU taking on more work. Low settings average 172 FPS, a 70 FPS drop from 1080p Low. Medium averages 138.5 FPS, and High averages 116 FPS. The Ultra preset at 1440p yields 74.3 FPS, which is a significant drop but still within a playable range for many users. The differences between settings at 1440p are consistent, with each step up in quality costing roughly 20-30 FPS.

At 3840x2160, the GPU is clearly the dominant factor. Low settings average 106.2 FPS, which is still respectable. Medium averages 89.2 FPS, and High averages 72.2 FPS. The Ultra preset, however, falls to 45.4 FPS, which is below the 60 FPS threshold commonly considered smooth. The gap between Low and Ultra at 4K is 60.8 FPS, demonstrating the massive performance cost of the highest settings at this resolution.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip. It features 2560 shading units, 160 texture mapping units, and 64 raster output units. The GPU has a base clock of 2150 MHz and a boost clock of 2600 MHz. Its 12 GB of GDDR6 memory operates on a 192-bit bus, providing 432.0 GB/s of bandwidth. This memory configuration is a key factor in the GPU's ability to handle 4K resolutions, where the data demands are highest.

The GPU's Passmark G3D score of 20700 places it in the 79th percentile of all GPUs. Its nearest rival, the AMD Radeon RX 5600M, scores 35264 on average, a 0.2% difference, while the NVIDIA GeForce RTX 3080 scores 35787, which is 1.3% higher. This indicates the RX 6750 XT is a capable performer, though not at the top tier. In Downfall, the GPU's role becomes more pronounced as resolution increases. At 4K Ultra, the 45.4 FPS average shows the GPU is the limiting component, with the 12 GB memory buffer being filled by high-resolution textures.

The GPU also supports DirectX 12 Ultimate and Vulkan 1.4, which are relevant for a game like Downfall released in 2016. The FP32 performance of 13.31 TFLOPS provides ample compute power for the game's horror-themed rendering. The 40 ray tracing cores are present but are not likely to be heavily utilized by a 2016 title. Overall, the GPU delivers a strong performance at 1440p and can handle 4K at lower settings, but the Ultra preset at 4K is beyond its comfortable capabilities.

Settings Recommendations

The data provides a clear picture of which settings offer the best balance of visual quality and performance. For users with a 1080p display, the High preset at 160.4 FPS is an excellent choice, offering a significant visual improvement over Medium's 194.8 FPS while still maintaining a very high frame rate. The Ultra preset at 103.5 FPS is also viable for those who prioritize maximum visual fidelity.

At 1440p, the High preset at 116 FPS provides the best experience. It delivers a smooth frame rate that is well above the 60 FPS threshold and offers better visuals than Medium's 138.5 FPS. The Ultra preset at 74.3 FPS is playable but may not be ideal for users sensitive to frame rate drops. For most players, High at 1440p is the recommended choice.

For 4K displays, the situation is more constrained. The Low preset at 106.2 FPS is the safest option, providing a smooth experience. Medium at 89.2 FPS is also good, and High at 72.2 FPS is acceptable for those who prioritize image quality. The Ultra preset at 45.4 FPS should be avoided unless the user is willing to accept a sub-60 FPS experience. The measured rows indicate that the best overall experience is 1440p High, which offers a strong balance of visual fidelity and performance without pushing the GPU to its limits.
