Lockdown Protocol

Lockdown Protocol with an AMD Ryzen 5 3600 and AMD Radeon RX 7900 XTX presents a classic high-end GPU paired with a previous-generation mid-range CPU. The benchmark data shows this combo is capable of very high frame rates, but the relationship between resolution, settings, and the two components reveals where the bottlenecks lie. The measured FPS across 1080p, 1440p, and 4K provides a clear picture of how this system scales under load, and the numbers indicate a system that is heavily GPU-bound at higher resolutions while ceding some ground to the CPU at lower ones.

Resolution Scaling

The performance drop from 1080p to 4K is substantial, but it is not uniform across all settings presets. At High settings, the average frame rate falls from 170.6 FPS at 1920x1080 to 138.2 FPS at 2560x1440, a decline of 32.4 FPS, and then further down to 88.1 FPS at 3840x2160. The most significant scaling occurs between 1440p and 4K, where the GPU must render roughly double the pixels. This is the clearest indicator that the Radeon RX 7900 XTX is the primary limiting component at 4K, as the 24 GB of GDDR6 memory and its 960.0 GB/s bandwidth are being taxed by the higher resolution workload.

Looking at the Low preset, the scaling pattern shifts. At 1080p Low, the system achieves 201.8 FPS, which drops to 182.7 FPS at 1440p and then to 142.3 FPS at 4K. The 19.1 FPS difference between 1080p and 1440p is smaller than the 40.4 FPS difference seen on the High preset, suggesting that at Low settings, the CPU has more headroom to keep up. However, the 4K Low result of 142.3 FPS is still significantly higher than the 4K High result of 88.1 FPS, confirming that the GPU is doing the heavy lifting. The data indicates that the Ryzen 5 3600, with its 6 cores and 12 threads, can feed the GPU adequately at 1080p Low, but the gap between Low and High at 1080p (201.8 vs 170.6 FPS) shows that CPU limitations emerge as the graphics load lightens.

The Ultra preset shows the steepest relative drop, going from 139.5 FPS at 1080p to 105.1 FPS at 1440p and finally to 65.2 FPS at 4K. The 4K Ultra result is less than half of the 1080p Low score, illustrating how quickly the GPU is saturated by the combination of maximum visual fidelity and high pixel count. This pattern is typical for a system where the GPU is the dominant factor in determining frame rates at higher resolutions, while the CPU's influence becomes more apparent only when the GPU has less work to do.

GPU Role

The Radeon RX 7900 XTX is the star of this pairing, and its specifications explain its behavior in Lockdown Protocol. With 24 GB of GDDR6 memory on a 384-bit bus, the card has ample capacity for any texture load the game can throw at it. The 960.0 GB/s bandwidth ensures that data flows quickly to the 6144 shading units. The boost clock of 2498 MHz and game clock of 2365 MHz provide the raw compute power needed to drive the high frame rates seen in the benchmark data. The GPU's performance percentile of 85 versus all other GPUs places it well above average, and its average benchmark score of 44019 is competitive with the NVIDIA GeForce RTX 4070 Ti, which sits just 2% behind in the nearest rivals data.

The measured results show that the GPU's power is best utilized at 1440p, where it produces 160.1 FPS on Medium and 138.2 FPS on High. At 4K, the card still delivers playable frame rates on High (88.1 FPS), but the drop to 65.2 FPS on Ultra suggests that the game's most demanding settings are designed to stress even top-tier hardware. The gap between Medium and High at 4K is 14.1 FPS (102.2 vs 88.1), which is a reasonable trade-off for the visual improvements. The GPU's compute capabilities, reflected in its 61.39 TFLOPS FP32 performance, are clearly sufficient for this title, as the system never falls below the 60 FPS threshold on any tested preset until the 4K Ultra setting.

Settings Recommendations

For this specific combination of CPU and GPU, the data points to 1440p High as the sweet spot. The 138.2 FPS average at this setting is smooth and leaves headroom for demanding scenes, while the visual quality is significantly better than the Medium preset's 160.1 FPS. The difference between High and Ultra at 1440p is notable, with Ultra dropping to 105.1 FPS—a 33.1 FPS loss for what is likely a marginal visual gain. At 1080p, High provides 170.6 FPS, which is excellent, but the CPU starts to show its age here; the jump to Low only gains 31.2 FPS, indicating a diminishing return as the GPU becomes less of a bottleneck.

At 4K, the recommendation becomes more nuanced. The High preset at 88.1 FPS is playable and looks good, but the Medium preset at 102.2 FPS offers a safer margin for maintaining frame rates during intense firefights. The Low preset at 142.3 FPS is a viable option for competitive play where frame rate trumps visuals, but it underutilizes the GPU's capabilities. Given the data, 4K Medium is the most balanced choice for this resolution, as it sacrifices some visual fidelity but stays well above the 60 FPS threshold. The Ultra preset at 65.2 FPS is only worth considering if you have a variable refresh rate monitor and prefer absolute maximum quality over consistency.

The bottleneck is real but manageable, and the GPU carries the system to good results.

CPU Role

The Ryzen 5 3600, with its 6 cores and 12 threads, is a Zen 2 architecture chip running on the AM4 socket. Its base clock of 3.60 GHz and boost clock of 4.20 GHz provide adequate single-thread performance, as evidenced by its 3DMark single-thread score of 696 and Cinebench R23 single-core score of 2124. The CPU's 32 MB of shared L3 cache helps with gaming workloads, but its 51.2 GB/s memory bandwidth is modest by modern standards. The data shows that the CPU's impact on Lockdown Protocol is most noticeable at 1080p, where the frame rate ceiling is lower than what the GPU could theoretically achieve.

In the benchmark results, the difference between the 1080p Low (201.8 FPS) and 1080p Medium (176.5 FPS) is just 25.3 FPS, while the gap between Medium and High (170.6 FPS) is only 5.9 FPS. This compression of frame rates at lower settings is a classic sign of CPU limitation. The CPU's percentile of 76 versus all CPUs, along with its average benchmark score of 18129, places it in the same performance tier as the Intel Core i5-11400, which is just 0.1% ahead. For Lockdown Protocol, the CPU provides enough power to avoid major stutters, but it prevents the system from fully utilizing the GPU's potential at 1080p. At 1440p and above, the GPU takes over as the primary driver of performance, and the CPU's role diminishes accordingly.
