Lockdown Protocol

Lockdown Protocol presents a demanding workload that shifts between CPU and GPU limitations depending on the resolution and quality preset selected. This analysis examines the AMD Ryzen 5 8400F paired with the AMD Radeon RX 6600 XT across 1080p, 1440p, and 4K resolutions, using measured frame rate data to characterize the behavior of this specific configuration.

Resolution Scaling

The measured frame rates reveal a predictable scaling pattern as resolution increases, but the magnitude of the performance drop is heavily influenced by the graphics settings. At the Low preset, the average frame rate falls from 159 FPS at 1920x1080 to 117 FPS at 2560x1440, a reduction of 42 FPS. Moving from 1440p to 4K at Low settings brings the average down to 75 FPS, another 42 FPS drop. This consistent step-down suggests that at Low settings, the GPU is the primary limiting factor at every resolution, as the frame rate scales almost linearly with the pixel count increase.

The High preset exhibits a similar pattern but with a steeper initial decline. At 1080p, the average is 99 FPS, which drops to 72 FPS at 1440p—a 27 FPS decrease. The transition to 4K is more severe, yielding just 47 FPS on average. The percentage loss from 1080p to 4K is approximately 52% at High settings, whereas the Low preset loses about 53% across the same resolution range. This relative consistency across presets indicates that the RX 6600 XT's rendering workload, not the CPU, is the dominant constraint when resolution climbs.

Ultra settings tell a different story. The 1080p average of 74 FPS falls to 54 FPS at 1440p, then to 35 FPS at 4K. The drop from 1440p to 4K here is 19 FPS, or roughly 35%, which is a smaller relative decrease than what is seen at Low or High settings. This compressed scaling at Ultra suggests that at 4K, the GPU is so heavily loaded that the frame rate is already near the floor for playable performance, and the additional pixel count has a diminishing absolute impact. The data indicates that this combo is capable of delivering fluid frame rates at 1080p and 1440p, but 4K gaming will require significant compromises in visual quality.

GPU Role

The AMD Radeon RX 6600 XT is built on the RDNA 2.0 architecture with the Navi 23 chip, fabricated on a 7 nm process. Its memory subsystem consists of 8 GB of GDDR6 across a 128-bit bus, providing a bandwidth of 256.0 GB/s. The GPU's boost clock reaches 2589 MHz, with a game clock of 2359 MHz and a base clock of 1968 MHz. These specifications position the card with 2048 shading units, 128 texture mapping units, and 64 raster operation units, which are directly relevant to Lockdown Protocol's rasterization demands.

In this game, the 8 GB VRAM capacity is a critical factor at higher resolutions. The measured data shows that at 4K Medium, the average frame rate is 53 FPS with a minimum of 45 FPS and maximum of 61 FPS. The fact that the frame times remain relatively stable, with a spread of 16 FPS between minimum and maximum, suggests that the GPU is not being forced to swap textures to system memory, which would cause pronounced stutters. However, the low average at 4K Ultra (35 FPS) indicates that the combination of resolution and settings is pushing the GPU's compute throughput to its limit, regardless of memory capacity.

The GPU's pixel rate of 165.7 GPixel/s and texture rate of 331.4 GTexel/s are the theoretical ceilings that govern fill-rate bound scenarios. In Lockdown Protocol, the scaling from Low to Ultra at 1080p shows a drop from 159 FPS to 74 FPS, which is a 53% reduction. This is a substantial performance cost for the visual fidelity uplift, implying that the game's effects, such as shadows and post-processing, are heavily taxing the GPU's shader and texture units. The FP32 performance of 10.60 TFLOPS provides the raw compute for these effects, and the data shows that at 4K Ultra, the card is delivering only about 22% of the frame rate it achieves at 1080p Low.

How This Combo Ranks

Within the benchmark database, this specific combination of the AMD Ryzen 5 8400F and AMD Radeon RX 6600 XT achieves a rank of 2630 out of 3714 tested combos for Lockdown Protocol. This places it in the lower third of all configurations, which is consistent with the mid-range positioning of both components. The combo rank reflects the aggregate performance across all tested resolutions and settings, and the measured data shows that this pairing is more suited to 1080p and 1440p gaming than to 4K.

The CPU's performance characteristics provide context for this ranking. The Ryzen 5 8400F has an average benchmark score of 25005, placing it in the 77th percentile of all CPUs. Its nearest rival in synthetic tests is the AMD Ryzen 5 7500F, which scores 24964, a delta of 0.2%. The Intel Core i7-11850H scores 24935, just 0.3% behind. This indicates that the 8400F is a solid mid-range processor that is unlikely to bottleneck the GPU in most gaming scenarios. However, the GPU's average benchmark score is 24442, placing it in the 70th percentile of all GPUs, with its nearest rival being the NVIDIA GeForce GTX 1630 at 24277, a 0.7% delta.

The combination rank of 2630 out of 3714 suggests that while each component is individually capable, the pairing does not unlock exceptional performance in Lockdown Protocol. The data implies that the RX 6600 XT is the limiting factor at higher resolutions, as the CPU's strong single-thread and multi-thread scores (3dmark_single_thread: 951, cinebench_r23_multicore: 20851) are more than adequate for the game's logic and physics. The combo is ranked below the median, meaning there are over 1000 combinations that deliver higher frame rates in this specific title.

Settings Recommendations

For players targeting a 60 FPS average, the data shows that this combo can achieve that at 1080p High with 99 FPS, and even at 1440p High with 72 FPS. The Medium preset offers a more balanced experience, with 113 FPS at 1080p and 83 FPS at 1440p, along with measured minimums of 96 and 70 FPS respectively, indicating stable frame delivery. At 4K, the Medium preset is the only option that approaches playability, with an average of 53 FPS and a minimum of 45 FPS, which may be acceptable for slower-paced segments but could feel inconsistent during action.

The Low preset should be reserved for competitive play where maximum frame rate is prioritized over visuals. It delivers 159 FPS at 1080p and 117 FPS at 1440p, providing a significant advantage in responsiveness. However, the visual downgrade is substantial, and the data shows that High settings at 1440p only reduce the frame rate by 38% compared to Low, from 117 to 72 FPS. This is a reasonable trade-off for the visual improvement.

Ultra settings are not recommended for this configuration at any resolution above 1080p. At 1080p Ultra, the average is 74 FPS, which is playable, but at 1440p, it drops to 54 FPS, and at 4K, it falls to 35 FPS. For a consistent experience, the Medium preset at 1440p offers the best balance of visual fidelity and performance, with an average of 83 FPS and a minimum of 70 FPS that keeps frame times within a comfortable range. At 4K, players should accept the Medium preset's 53 FPS average or reduce the resolution to maintain higher frame rates.

Measured FPS Breakdown

At 1920x1080, the configuration delivers an average of 159 FPS on Low, 113 FPS on Medium (with a minimum of 96 and maximum of 130), 99 FPS on High, and 74 FPS on Ultra. The scaling from Low to Ultra shows a 53% reduction in average frame rate, from 159 to 74 FPS. The Medium preset's minimum of 96 FPS indicates that even in demanding scenes, the frame rate stays well above 60 FPS, suggesting a smooth experience.

At 2560x1440, the average frame rates are 117 FPS on Low, 83 FPS on Medium (minimum 70, maximum 95), 72 FPS on High, and 54 FPS on Ultra. The Medium preset's minimum of 70 FPS is still above the 60 FPS threshold, making it a viable option for high-refresh-rate monitors. The High preset's 72 FPS average is also playable, but the lack of a recorded minimum suggests that frame dips could occur.

At 3840x2160, the averages drop significantly: 75 FPS on Low, 53 FPS on Medium (minimum 45, maximum 61), 47 FPS on High, and 35 FPS on Ultra. The Medium preset's minimum of 45 FPS represents the lowest measured point across all tested configurations, and it highlights the GPU's struggle at 4K. The Low preset's 75 FPS average is the only setting that offers a comfortable margin above 60 FPS at this resolution, but it comes with the most significant visual compromises.

The data shows a clear hierarchy: 1080p Low is the fastest measured configuration, while 4K Ultra is the slowest. The gap between these two extremes is 124 FPS, or a 78% reduction in average frame rate. This range demonstrates the wide performance envelope of this combo, which is capable of esports-level frame rates at low settings but falls to console-level performance at maximum fidelity.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Phoenix, and manufactured on a 4 nm process by TSMC. Its base clock is 4.20 GHz with a boost clock of 4.70 GHz, and it features a 16 MB shared L3 cache. The CPU's memory bandwidth is 83.2 GB/s over a dual-channel DDR5 interface, which is sufficient for feeding the GPU's 256.0 GB/s bandwidth without creating a bottleneck in most gaming workloads.

In Lockdown Protocol, the CPU's role appears to be secondary to the GPU at higher resolutions, but it becomes more significant at 1080p Low where the frame rate reaches 159 FPS. At this level, the CPU's single-thread performance, as measured by a 3dmark_single_thread score of 951 and a cinebench_r23_singlecore score of 2943, is critical for maintaining high frame rates. The multi-thread capabilities, evidenced by a cinebench_r23_multicore score of 20851, ensure that background tasks and game logic do not interfere with frame delivery.

The CPU's nearest rivals in synthetic benchmarks include the AMD Ryzen 5 7500F, which scores 24964 (0.2% lower), and the Intel Core i7-13620H at 24911 (0.4% lower). The AMD EPYC 9474F scores 25103, which is 0.4% higher. These small deltas indicate that the 8400F is well-matched to its peers, and its 77th percentile ranking among all CPUs suggests it has ample headroom for this game. The measured FPS data shows that this CPU does not bottleneck the RX 6600 XT, as the frame rates scale consistently with resolution changes, which would not occur if the CPU were the limiting factor. The 12 threads are more than adequate for Lockdown Protocol's threaded rendering, and the 4 nm process keeps power consumption low at 65 W TDP, allowing the GPU to operate without thermal constraints from the processor.
