Lockdown Protocol

The AMD Ryzen 5 8400F and AMD Radeon RX 9070 combination delivers a robust experience in Lockdown Protocol, with performance scaling predictably across resolutions. The data indicates that this pairing is well-balanced for high-refresh-rate 1080p and 1440p gaming, while 4K remains playable with adjustments. This analysis breaks down the measured results to guide settings and expectations.

Resolution Scaling

The measured FPS data reveals a clear and consistent pattern of performance degradation as resolution increases from 1920x1080 to 3840x2160. At High settings, the average frame rate drops from 152 FPS at 1080p to 112 FPS at 1440p, a reduction of 26.3%. Moving further to 4K, the average falls to 72 FPS, which represents a 36% decrease from the 1440p figure and a 52.6% drop from the 1080p baseline. This scaling behavior indicates that the Radeon RX 9070's rendering load is the primary constraint at higher resolutions, as the GPU must process significantly more pixels.

The Low settings preset demonstrates even steeper scaling, with average FPS going from 245 at 1080p down to 180 at 1440p and then to 116 at 4K. The 1080p to 4K transition at Low settings shows a 52.7% performance reduction, nearly identical to the percentage drop seen at High settings. This similarity suggests that the resolution scaling penalty is relatively uniform across different quality presets, which is typical for a GPU-bound scenario where pixel throughput dominates.

Ultra settings exhibit the most severe resolution impact. At 1080p, the average is 114 FPS, which falls to 84 FPS at 1440p and 54 FPS at 4K. The 4K result is only 47.4% of the 1080p performance, indicating that the Ultra preset's additional graphical effects place an outsized burden on the GPU at higher pixel counts. The data shows that the RX 9070's 16 GB of GDDR6 memory and 644.6 GB/s bandwidth are sufficient for the data loads, but the raw compute throughput of 36.13 TFLOPS becomes the limiting factor.

The Medium preset provides the most complete dataset, including minimum and maximum FPS values. At 1080p, the average is 174 FPS with a minimum of 148 and maximum of 200. At 1440p, the average drops to 128 FPS with a minimum of 109 and maximum of 147. At 4K, the average is 82 FPS with a minimum of 70 and maximum of 95. The minimum FPS values at each resolution stay within 15-16% of the average, suggesting consistent frame pacing without severe stutters. This consistency indicates that the Ryzen 5 8400F's six cores and 12 threads are adequately feeding the GPU, preventing CPU-related frame drops.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, built on TSMC's 4 nm process. Its base clock of 4.20 GHz and boost clock of 4.70 GHz provide solid single-thread performance, as evidenced by its 3DMark single-thread score of 951. In Lockdown Protocol, an FPS title, single-thread performance is often critical for game logic and draw call submission. The processor's 16 MB of shared L3 cache helps keep frequently accessed data close to the cores, reducing latency.

The CPU's benchmark results place it in the 77th percentile among all tested CPUs, with an average benchmark score of 25,005. Its nearest rivals in aggregate performance include the AMD Ryzen 5 7500F, which scores 24,964 (a 0.2% difference), and the Intel Core i7-13620H, which scores 24,911 (a 0.4% difference). This close grouping indicates that the 8400F performs competitively with these alternatives in general compute tasks. The multi-threaded performance, shown by a Cinebench R23 multi-core score of 20,851, ensures that background tasks and modern game engines that utilize multiple threads do not bottleneck the RX 9070.

In the context of Lockdown Protocol, the measured FPS data suggests that the CPU is not the limiting factor at 1080p, where the GPU is typically the bottleneck. At 1080p Low settings, the combination reaches 245 FPS, which is a very high frame rate that requires strong CPU throughput to maintain. The fact that the system achieves this score indicates that the 8400F's single-thread performance is sufficient to drive the RX 9070 to near its maximum output at lower resolutions. The 3DMark 16-thread score of 6,091 and max-thread score of 6,165 show that the processor scales well with additional threads, though the gains from 8 to 16 threads are modest, suggesting diminishing returns for this workload.

At 4K Ultra settings, where the system drops to 54 FPS, the CPU's role is minimized as the GPU becomes fully saturated. The data shows that the system's performance is consistently GPU-bound at higher resolutions, with the CPU maintaining frame delivery without introducing stutter. The 2-thread 3DMark score of 1,874 and 4-thread score of 3,563 indicate that the processor's per-core strength is adequate for the game's primary thread, while the 12 threads provide headroom for other system processes.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four quality settings. At 1920x1080, the system delivers its highest frame rates. Low settings produce an average of 245 FPS, Medium settings yield 174 FPS with a minimum of 148 and maximum of 200, High settings reach 152 FPS, and Ultra settings drop to 114 FPS. These numbers indicate that 1080p gaming is exceptional, with even Ultra settings providing smooth gameplay on high-refresh-rate monitors.

At 2560x1440, the performance remains strong. Low settings achieve an average of 180 FPS, Medium settings drop to 128 FPS with a minimum of 109 and maximum of 147, High settings reach 112 FPS, and Ultra settings fall to 84 FPS. The 1440p results show that the RX 9070 is well-suited for this resolution, as even Ultra settings maintain an average above 60 FPS, providing a good balance between visual quality and performance for most players.

At 3840x2160, the system begins to show its limits. Low settings still produce a respectable 116 FPS, but Medium settings drop to 82 FPS with a minimum of 70 and maximum of 95. High settings yield 72 FPS, and Ultra settings fall to 54 FPS. The 4K data shows that while the system can handle 4K gaming, it requires settings reductions to maintain high frame rates. The Medium preset offers the best balance at 4K, with an average of 82 FPS that is close to the 72 FPS of High settings but with a higher minimum frame rate of 70 FPS, suggesting better consistency.

The data across all resolutions shows a consistent pattern: the gap between Low and Medium settings is significant, while the gap between Medium and High is smaller, and the gap between High and Ultra is moderate. For example, at 1080p, the difference between Low and Medium is 71 FPS, between Medium and High is 22 FPS, and between High and Ultra is 38 FPS. This suggests that the Low preset removes many GPU-intensive effects, while the Ultra preset adds effects that have a notable performance cost.

Settings Recommendations

For players targeting the highest possible frame rates, particularly for competitive play, the Low preset at 1080p offers 245 FPS, which is ideal for 240Hz monitors. At 1440p, Low settings still provide 180 FPS, making it a strong choice for high-refresh-rate 1440p displays. The Low preset sacrifices visual fidelity but delivers the smoothest gameplay experience, with the data showing that the system has ample headroom in these configurations.

For a balanced experience that maintains good visual quality without sacrificing performance, the Medium preset is the recommended choice across all resolutions. At 1080p, it delivers 174 FPS with a minimum of 148, which is well above the 144Hz threshold for most monitors. At 1440p, the 128 FPS average with a 109 FPS minimum provides smooth gameplay that is still competitive. At 4K, Medium settings achieve 82 FPS, which is the best balance of quality and speed at that resolution. The Medium preset's consistent minimum frame rates, as shown in the data, suggest it provides the most stable experience.

The High preset is a viable option for players prioritizing visual quality over raw frame rate. At 1080p, it delivers 152 FPS, which is still very smooth. At 1440p, the 112 FPS average is acceptable for most gaming scenarios. However, at 4K, High settings drop to 72 FPS, which may be borderline for some players, especially in fast-paced FPS gameplay where frame consistency is critical. The Ultra preset is not recommended for 4K gaming, as the 54 FPS average falls below the 60 FPS threshold that most players consider the minimum for smooth play. At 1080p and 1440p, Ultra settings provide 114 FPS and 84 FPS respectively, which are playable but represent a significant performance cost for the additional visual effects.

In summary, the data suggests that the Medium preset offers the best all-around experience, providing high frame rates with good visual quality across all resolutions. For competitive players, Low settings at 1080p or 1440p are the optimal choice to maximize frame rates. For casual players who prioritize visuals, High settings at 1080p or 1440p deliver a good experience, while 4K gaming should be limited to Medium settings to maintain playable frame rates.
