Lockdown Protocol

How This Combo Ranks

The Intel Core i5-13400F paired with the AMD Radeon RX 6600 lands at rank 1307 out of 1637 tested combos in Lockdown Protocol, placing it in the 20th percentile of all system pairings. This is a mid-pack result, but the story is more nuanced than the raw rank suggests. The CPU is a standout performer in its class, sitting at the 82nd percentile against all CPUs, while the GPU trails at the 69th percentile against all GPUs. That gap indicates the Radeon RX 6600 is the primary constraint in this pairing, a conclusion supported by the measured frame rates across resolutions.

Benchmark data shows this combo is neither a high-refresh-rate specialist nor a 4K powerhouse. It occupies a workable middle ground, delivering playable frame rates at 1080p and 1440p with adjusted settings, but falling short of smooth performance at 4K. The combination's ranking reflects this reality: it outperforms roughly 20% of tested systems, which is consistent with a GPU that ranks in the lower third of all graphics cards. The CPU's 82nd percentile ranking, however, means there is headroom for a future GPU upgrade without a platform change.

When comparing the components to their nearest rivals, the performance deltas are remarkably tight. The Core i5-13400F scores 25236 in average benchmark score, essentially matching the Intel Core i7-13620H (25201, +0.1%) and the AMD Ryzen 5 5600X3D (25365, -0.5%). The AMD EPYC 9474F and AMD Ryzen AI 5 PRO 340 are also within 0.5% of the i5-13400F, showing that this chip delivers performance comparable to far more expensive or power-hungry alternatives.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on Raptor Lake architecture, built on Intel's 10 nm process. It operates with a base clock of 2.50 GHz and a boost clock of 4.60 GHz, with a 65W TDP. The CPU supports DDR4 and DDR5 memory in a dual-channel configuration, and its 20 MB of shared L3 cache provides ample capacity for game data. The processor's benchmark scores reinforce its strength: it achieves 21279 in Cinebench R23 multi-core, 3004 in single-core, and 10971 in Geekbench multi-core.

In Lockdown Protocol, the CPU's role is to feed the GPU with draw calls and game logic. The 3DMark results show strong scaling from 2 threads (1880) to 8 threads (5591) and 16 threads (7314), indicating that the game can leverage multiple cores effectively. The single-thread score of 960 in 3DMark is adequate for maintaining high frame rates at lower resolutions, where the CPU is less likely to become a bottleneck. The Passmark multi-thread score of 25032 places this chip in the top 18% of all CPUs, and its nearest rivals—the Core i7-13620H, Ryzen 5 5600X3D, EPYC 9474F, and Ryzen AI 5 PRO 340—all deliver within 0.5% of its performance.

The CPU's 82nd percentile ranking means it is substantially more capable than the GPU in this pairing. At 1080p Low, the combo reaches 148.3 average FPS, which approaches the point where CPU limitations could start to appear, but even this does not fully saturate the i5-13400F's capabilities. The processor's 10 cores and 16 threads provide enough parallel processing headroom for the game's physics and AI workloads, while the 2.50 GHz base clock ensures sustained performance under load. The lack of an integrated GPU means the discrete Radeon RX 6600 handles all rendering duties, a design choice that keeps the CPU's thermal envelope low at 65W.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings presets, providing a complete picture of the combo's capabilities. At 1920x1080, the average frame rates are 148.3 at Low, 105.9 at Medium, 92.0 at High, and 65.4 at Ultra. This range shows that the combo can push well beyond 100 FPS at lower settings, making it suitable for competitive play where frame rate matters more than visual fidelity. The step from Low to Medium costs 42.4 FPS (a 29% drop), while the step from High to Ultra costs 26.6 FPS (a 29% drop), indicating that Ultra settings impose a heavy penalty.

At 2560x1440, performance scales down proportionally. The averages are 110.1 at Low, 77.1 at Medium, 65.6 at High, and 51.0 at Ultra. The gap between Low and Medium is 33.0 FPS (a 30% drop), and the gap between High and Ultra is 14.6 FPS (a 22% drop). This resolution still offers playable frame rates at Medium and High, but Ultra dips below 60 FPS, which may be noticeable in fast-paced FPS gameplay.

At 3840x2160, the combo struggles to maintain playable performance. The averages are 71.9 at Low, 48.5 at Medium, 41.4 at High, and 35.0 at Ultra. Only the Low preset clears 60 FPS, and even then by a narrow margin. The scaling from 1080p to 4K is steep: at Low, the drop is 76.4 FPS (52%), and at Ultra, it is 30.4 FPS (47%). These numbers confirm that the Radeon RX 6600's 8 GB of GDDR6 memory and 224.0 GB/s bandwidth are insufficient for 4K gaming at higher quality settings.

Resolution Scaling

The resolution scaling data reveals a GPU-bound system. Moving from 1920x1080 to 2560x1440 at High settings, the average FPS drops from 92.0 to 65.6, a 29% reduction. Moving from 2560x1440 to 3840x2160 at High, the average FPS drops from 65.6 to 41.4, a 37% reduction. These percentage drops are consistent with what would be expected from a GPU that is already operating near its limits at lower resolutions.

The pattern is similar across all settings presets. At Low, the drop from 1080p to 1440p is 38.2 FPS (26%), and from 1440p to 4K is 38.2 FPS (35%). At Medium, the drops are 28.8 FPS (27%) and 28.6 FPS (37%). At Ultra, the drops are 14.4 FPS (22%) and 16.0 FPS (31%). The consistent percentage reductions indicate that the GPU's pixel throughput, not the CPU's processing power, is the limiting factor. The Radeon RX 6600's pixel rate of 159.4 GPixel/s and texture rate of 279.0 GTexel/s are the hardware parameters that govern this scaling behavior.

The CPU's role in resolution scaling is minimal. Since the i5-13400F's performance does not degrade with lower resolutions (in fact, it has headroom for more frames), the FPS drops at higher resolutions are entirely attributable to the GPU. This is further evidenced by the fact that the combo's rank in the game (1307 out of 1637) does not change based on resolution, suggesting that the system's overall position is determined by the GPU's capabilities rather than the CPU's.

Settings Recommendations

For the best experience in Lockdown Protocol, the data points to Medium settings as the optimal preset. At 1920x1080, Medium delivers 105.9 average FPS, which is well above the 60 FPS threshold and close to the 148.3 FPS achievable at Low. The visual quality improvement from Low to Medium is significant, and the 42.4 FPS penalty is acceptable for most players. At 2560x1440, Medium provides 77.1 average FPS, which remains smooth and playable. The step from Medium to High at 1440p costs 11.5 FPS, bringing the average down to 65.6, which is still playable but closer to the edge.

At 3840x2160, the recommendation changes. The only playable preset is Low, which achieves 71.9 average FPS. Medium drops to 48.5, which is below the ideal threshold for a competitive FPS. For players who prioritize frame rate over visual quality, 1080p Low offers the highest possible performance at 148.3 average FPS, but this comes at the cost of visual fidelity. The data does not support Ultra settings at any resolution, as even at 1080p, Ultra only reaches 65.4 average FPS, which is a 38% reduction from Medium.

The GPU's 8 GB VRAM capacity is a consideration for settings selection. At higher resolutions and quality presets, the memory requirements increase, and the Radeon RX 6600's 8 GB GDDR6 memory may become a limiting factor, especially in texture-heavy scenes. The 14 Gbps effective memory speed and 128-bit bus width provide 224.0 GB/s of bandwidth, which is adequate for 1080p and 1440p but strained at 4K. Based on the measured data, Medium at 1080p or 1440p offers the best balance of performance and visual quality for this combo.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with the Navi 23 chip, manufactured on a 7 nm process at TSMC. It features 1792 shading units, 112 texture mapping units, and 64 render output units, with 28 ray tracing cores. The GPU operates at a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz, with a 132W TDP. The 8 GB of GDDR6 memory runs at 1750 MHz (14 Gbps effective) across a 128-bit bus, delivering 224.0 GB/s of bandwidth.

In Lockdown Protocol, the GPU's role is dominant. The measured FPS data shows that the combo's performance is directly tied to the GPU's capabilities, as evidenced by the sharp performance drops at higher resolutions. The GPU's 69th percentile ranking against all GPUs places it in the upper third of graphics cards, but its average benchmark score of 25235 is nearly identical to its nearest rivals. The AMD Radeon 890M (25246), AMD Radeon RX 580 2048SP (25287), AMD Radeon RX 6700M (25180), and NVIDIA GeForce RTX 3060 Ti (25120) all perform within 0.5% of the RX 6600, making this a highly competitive segment.

The GPU's FP32 performance of 8.928 TFLOPS and texture rate of 279.0 GTexel/s are adequate for 1080p and 1440p gaming, but the 4K results show the limits of this hardware. At 4K Ultra, the combo only achieves 35.0 average FPS, which is below the 60 FPS target. The GPU's 8 GB VRAM capacity is also a factor at 4K, as higher resolutions require more memory for textures and frame buffers. The 224.0 GB/s bandwidth is a bottleneck at 4K, explaining the 47-52% FPS drops from 1080p to 4K depending on settings.

The GPU's end-of-life production status and RDNA 2.0 architecture place it in the previous generation, but its performance in Lockdown Protocol remains competitive with newer integrated graphics like the Radeon 890M. The 28 ray tracing cores provide some future-proofing, though the game's performance at 4K suggests that this GPU is best suited for 1080p and 1440p gaming. The data clearly shows that the GPU is the limiting component in this combo, and any performance improvements would require a GPU upgrade rather than a CPU change.
