Lockdown Protocol

The AMD Ryzen 5 8400F and AMD Radeon RX 7900 XT combination delivers a high-refresh-rate experience in Lockdown Protocol, with the data showing a clear shift in system bottleneck as resolution scales. The measured frame rates indicate that this pairing is exceptionally strong at 1080p, where the CPU becomes the primary limiting factor, while at 4K, the GPU's workload dominates performance. This analysis breaks down the specific roles of each component, the impact of resolution scaling, and how this combo ranks against the broader database of tested configurations.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, built on a 4 nm process. Its base clock is 4.20 GHz with a boost clock of 4.70 GHz, and it features a 16 MB shared L3 cache. In synthetic benchmarks, the CPU achieves a Cinebench R23 multi-core score of 20851 and a single-core score of 2943, alongside a Passmark single-thread score of 3684. These figures place the processor in the 82nd percentile among all CPUs, with an average benchmark score of 25064. The nearest rival is the AMD Ryzen 7 2700X, which scores 25057, a delta of 0%, while the AMD Ryzen 5 7500F scores 24993, a delta of 0.3% lower.

In Lockdown Protocol, the CPU's role is most evident at 1080p resolution with Low settings, where the system achieves 282.7 FPS. This high frame rate suggests that the game's engine can utilize the processor's multi-threading capabilities effectively. The 6-core/12-thread configuration provides ample parallel processing for game logic and physics, but the 16 MB L3 cache might be a limiting factor in scenarios with large data sets. At 1080p Medium, the frame rate drops to 200.7 FPS, and at High it falls to 171.8 FPS, indicating that while the CPU handles the base workload, the increasing graphical demands start to engage the GPU more.

Comparatively, the data shows that the Ryzen 5 8400F performs nearly identically to the Ryzen 7 2700X in average benchmark scores, with a delta of 0%. This means that in CPU-bound scenarios, users should expect similar performance to that older 8-core part. However, the single-thread performance of the 8400F is notably strong, which benefits games like Lockdown Protocol that may rely on a primary game thread. The boost clock of 4.70 GHz ensures that single-threaded tasks are handled swiftly, which is critical for maintaining high minimum frame rates, even if the data only provides average FPS values.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 7900 XT is a high-end graphics card built on the RDNA 3.0 architecture, featuring 20 GB of GDDR6 memory on a 320-bit bus, delivering a bandwidth of 800.0 GB/s. Its boost clock is 2394 MHz, with a game clock of 2025 MHz. The card has 5376 shading units and 84 ray tracing cores. In synthetic tests, it achieves a Passmark G3D score of 29009 and a Geekbench OpenCL score of 169834, placing it in the 82nd percentile among all GPUs. The nearest rival is the NVIDIA GeForce RTX 5080 Mobile with an average score of 38349, a delta of 0%, while the NVIDIA GeForce RTX 4080 Mobile scores 38135, a delta of 0.6% lower.

In Lockdown Protocol, the GPU's performance is best illustrated at 4K resolution. At 4K Ultra settings, the system produces 65 FPS, while at 4K High it reaches 79.9 FPS, and at 4K Medium it hits 95.3 FPS. The 20 GB VRAM is more than sufficient for this game at any settings or resolution, as the data shows no indication of memory-related stutters or crashes. The high memory bandwidth of 800.0 GB/s is likely a key factor in maintaining consistent frame rates at 4K, where texture streaming and data transfer demands are highest.

The GPU's compute power, reflected in its 51.48 TFLOPS FP32 performance, is well-utilized in Lockdown Protocol's rendering pipeline. At 1080p Low, the system achieves 282.7 FPS, which is significantly higher than the 4K Low result of 136 FPS. This gap demonstrates that the GPU is not the bottleneck at lower resolutions, as the card has enough headroom to render frames far faster than the CPU can feed it. The RDNA 3.0 architecture's efficiency is evident in the scaling from 1080p to 4K, where the GPU's workload increases substantially, yet it still manages playable frame rates at Ultra settings.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data across resolutions reveals a classic pattern of bottleneck shifting. At 1920x1080 with Low settings, the system achieves 282.7 FPS. This drops to 204.5 FPS at 2560x1440 Low, and then to 136 FPS at 3840x2160 Low. The percentage drop from 1080p to 1440p is approximately 27.7%, while the drop from 1440p to 4K is approximately 33.5%. This steep decline indicates that the GPU is increasingly becoming the limiting factor as resolution rises, since the CPU's workload remains relatively constant while the pixel count quadruples from 1440p to 4K.

At High settings, the same trend is visible: 171.8 FPS at 1080p, 124.5 FPS at 1440p, and 79.9 FPS at 4K. The drop from 1080p to 1440p is 27.5%, and from 1440p to 4K is 35.8%. The larger drop at higher resolutions confirms that the RX 7900 XT is being pushed harder, but the absolute frame rates remain high enough for competitive play. At Ultra settings, the system hits 133.5 FPS at 1080p, 97.6 FPS at 1440p, and 65 FPS at 4K. The 4K Ultra result is the only configuration that falls below the 70 FPS threshold, suggesting that this is the most demanding preset.

The data indicates that at 1080p, the CPU is the primary limiter. The Ryzen 5 8400F's 6 cores and 12 threads are capable of driving high frame rates, but the gap between 1080p Low (282.7 FPS) and 1080p Ultra (133.5 FPS) shows that the GPU still handles a significant portion of the workload. However, the relatively small difference between 1080p Low and 1080p Medium (200.7 FPS) suggests that the CPU's ability to feed the GPU is reaching its ceiling. Conversely, at 4K, the GPU is unequivocally the bottleneck, as the frame rates scale inversely with settings complexity, and the CPU has ample headroom to keep up with the reduced frame production demands.

How This Combo Ranks

In the database of tested combinations, this pairing of AMD Ryzen 5 8400F and AMD Radeon RX 7900 XT holds the rank of 312 out of 1637 combos for Lockdown Protocol. This places it in the top 19.1% of all tested systems, which is a strong showing. The rank is influenced by the CPU's 82nd percentile standing among all CPUs and the GPU's 82nd percentile among all GPUs. The CPU's average benchmark score of 25064 is nearly identical to the AMD Ryzen 7 2700X (25057), indicating that the processor is not a weak link in this combo.

The rank of 312 suggests that while the combo is powerful, there are many other configurations that deliver higher frame rates in this specific game. The GPU's performance, while excellent, is matched by several mobile GPUs in synthetic tests, which might not translate directly to desktop gaming performance. The combo's strength lies in its balanced nature: the CPU does not hold back the GPU at high resolutions, and the GPU provides enough horsepower to push high refresh rates at 1080p. However, the 4K Ultra result of 65 FPS is below the 70 FPS threshold that many enthusiasts prefer, which might explain why it does not rank higher.

Measured FPS Breakdown

| 1920x1080 | Medium | 200.7 |

| 1920x1080 | Ultra | 133.5 |

The data reveals a consistent pattern: at any given resolution, Low settings yield the highest frame rate, followed by Medium, High, and Ultra. The largest absolute difference between settings is at 1080p, where Low (282.7 FPS) outperforms Ultra (133.5 FPS) by 149.2 FPS. At 4K, the difference between Low (136 FPS) and Ultra (65 FPS) is 71 FPS. This scaling indicates that the GPU's compute units and memory bandwidth are heavily taxed by the higher graphical presets, particularly at 4K. For competitive players seeking maximum frame rates, 1080p Low is the clear choice, while those prioritizing visual fidelity can opt for 4K High, which still delivers a smooth 79.9 FPS.
