Lockdown Protocol

The Intel Core i5-10400F paired with the AMD Radeon RX 6600 XT delivers a playable experience in Lockdown Protocol, but the data reveals a system that scales predictably with resolution and settings. At 1080p, the combination is capable of high refresh rates, while 4K pushes the GPU to its limits. This analysis breaks down the measured FPS across twelve distinct configurations, focusing on where the bottleneck shifts between the CPU and GPU.

Resolution Scaling

The measured FPS data shows a clear and consistent drop as resolution increases from 1920x1080 to 3840x2160, which is expected for a GPU-bound title. At High settings, the average frame rate falls from 97.8 FPS at 1080p to 73.4 FPS at 1440p, a reduction of 24.4 FPS. Moving to 4K, the average drops further to 49.8 FPS, representing a 49% decrease from the 1080p figure. This scaling pattern indicates that the RX 6600 XT is the primary limiting factor at higher resolutions, as the workload on the GPU increases significantly with pixel count.

The scaling is even more pronounced at the Ultra preset. At 1080p, the system manages 73.4 FPS, which falls to 53.9 FPS at 1440p and then to 35.4 FPS at 4K. The 4K Ultra result is below the 60 FPS threshold that many users consider the baseline for smooth gameplay, suggesting that this preset is too demanding for the combination at ultra-high resolutions. The drop from 1440p to 4K at Ultra is 18.5 FPS, a 34% reduction, which highlights the exponential cost of pushing more pixels.

Conversely, the Low preset shows the least severe scaling. At 1080p Low, the system achieves 160.5 FPS, which is the highest measured result in the entire dataset. At 1440p Low, this falls to 118.3 FPS, and at 4K Low, it remains at a respectable 74.2 FPS. The 4K Low result is still higher than the 1080p Ultra result of 73.4 FPS, which indicates that the Low preset relieves enough GPU pressure to allow for higher resolutions without sacrificing frame rate. This suggests that for users prioritizing frame rate over visual fidelity, the Low preset at 1440p or 4K is a viable option.

The data indicates that at 1080p, the system is not fully GPU-bound. The difference between Low (160.5 FPS) and Ultra (73.4 FPS) at 1080p is substantial, showing that the CPU can feed the GPU with enough frames to exploit lower settings. However, the gap narrows at higher resolutions, confirming that the GPU becomes the bottleneck as resolution increases. The scaling analysis suggests that 1440p High is the sweet spot for balancing visual quality and performance, while 4K is only suitable for the Low or Medium presets.

GPU Role

The AMD Radeon RX 6600 XT, built on the RDNA 2.0 architecture with a 7 nm process, is the driving force behind the visual output in Lockdown Protocol. Its 8 GB of GDDR6 memory on a 128-bit bus provides a bandwidth of 256.0 GB/s, which is sufficient for the textures and assets at 1080p and 1440p. At 4K, the memory capacity and bandwidth become more strained, which is reflected in the significant FPS drops observed at the High and Ultra presets.

The GPU's clock speeds are a key indicator of its performance headroom. The base clock is 1968 MHz, with a game clock of 2359 MHz and a boost clock of 2589 MHz. The boost clock is the maximum sustained frequency under load, and the data suggests that the GPU is hitting these high frequencies in less demanding scenarios. However, at 4K Ultra, the GPU is likely operating at its limit, as evidenced by the 35.4 FPS average. This is the lowest result in the dataset, indicating that the GPU's compute resources are fully saturated.

The RX 6600 XT has 2048 shading units, 128 texture mapping units, and 64 render output units, along with 32 ray accelerators. The pixel rate of 165.7 GPixel/s and texture rate of 331.4 GTexel/s are substantial for a mid-range card, but they are not enough to handle 4K Ultra in a modern FPS. The FP32 performance of 10.60 TFLOPS is a measure of raw compute power, and the benchmark results show that the card sits in the 71st percentile of all GPUs, with an average benchmark score of 27985. Its nearest rival is the NVIDIA GeForce GTX 980 Ti, which has an average score of 27956, a delta of 0.1%, indicating that the RX 6600 XT is marginally faster in synthetic tests.

In practical terms, the GPU's role is to maintain frame rates above the playable threshold. At 1440p High, the card achieves 73.4 FPS, which is a smooth experience. The data shows that the GPU is the limiting factor at 4K, where even the Low preset (74.2 FPS) requires a significant reduction in visual fidelity to achieve playable frame rates. The card's 8 GB VRAM is adequate for 1080p and 1440p, but users pushing 4K may encounter texture pop-in or stuttering if VRAM is exceeded, although the measured data does not explicitly confirm this.

CPU Role

The Intel Core i5-10400F provides the processing foundation for this system, and its role in Lockdown Protocol is to feed the GPU with draw calls and game logic. This is a 6-core, 12-thread processor based on the Comet Lake architecture, manufactured on a 14 nm process. Its base clock is 2.90 GHz, with a boost clock of 4.30 GHz, and it has a 12 MB shared L3 cache. The CPU's benchmark scores show a balanced profile, with a single-thread score of 688 in 3DMark and a multi-thread score of 4748 in the 16-thread test.

The CPU's performance in synthetic benchmarks places it in the 73rd percentile of all CPUs, with an average benchmark score of 14168. Its nearest rival is the AMD EPYC 7552, which has an average score of 14115, a delta of 0.4%, meaning the i5-10400F is slightly faster. This indicates that the CPU is a competent performer for its class, but it is not a high-end part. In Lockdown Protocol, the CPU's role is more critical at lower resolutions where the GPU can produce frames faster, reducing the likelihood of a CPU bottleneck.

At 1080p Low, the system achieves 160.5 FPS, which is likely near the CPU's limit for this game. The difference between 1080p Low (160.5 FPS) and 1440p Low (118.3 FPS) is 42.2 FPS, which is a larger drop than the difference between 1440p Low and 4K Low (44.1 FPS). This suggests that the CPU is capable of driving high frame rates, but the GPU becomes the limiting factor as resolution increases. The CPU's 6 cores and 12 threads are sufficient for modern FPS titles, and the data does not show any significant CPU-related stuttering or frame drops.

The memory bandwidth of 42.7 GB/s for the CPU is a potential bottleneck in CPU-intensive scenarios, but the measured FPS data does not indicate that this is a major issue. The CPU's boost clock of 4.30 GHz is respectable for gaming, and its single-thread performance in Cinebench R23 (1453 points) is adequate for handling game logic. The data suggests that the i5-10400F is well-matched with the RX 6600 XT, as neither component is severely underpowered relative to the other, but the GPU is the more significant factor in determining performance at higher resolutions.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user's resolution and performance goals. For 1080p, the High preset delivers 97.8 FPS, which is smooth for competitive play. The Medium preset at 110.7 FPS offers a slight performance boost with a minor visual trade-off, making it a strong choice for users who prioritize frame rate. The Ultra preset at 73.4 FPS is still playable but does not provide a significant visual improvement over High to justify the 24.4 FPS loss.

For 1440p, the High preset is the recommended choice, as it achieves 73.4 FPS, which is above the 60 FPS threshold for smooth gameplay. The Medium preset at 85.7 FPS is an alternative for users who want a higher frame rate, but the visual difference between Medium and High is often minimal in fast-paced FPS titles. The Ultra preset at 53.9 FPS is below the ideal threshold and should be avoided unless the user prioritizes visual fidelity over performance.

For 4K, the Low preset is the only option that provides a consistently smooth experience, with 74.2 FPS. The Medium preset at 53.8 FPS is borderline playable, but the frame rate may dip below 60 FPS in intense scenes. The High preset at 49.8 FPS and Ultra at 35.4 FPS are not recommended for 4K, as they do not meet the playability standard. The data suggests that the RX 6600 XT is not designed for 4K Ultra in Lockdown Protocol, and users should either lower the resolution or adjust settings to the Low or Medium presets to maintain a playable frame rate. Overall, the High preset at 1440p provides the best balance of visual quality and performance, while the Low preset at 1080p is the best for maximizing frame rate.
