Lockdown Protocol

# Lockdown Protocol with Intel Core i5-12400F + AMD Radeon RX 6600

The Intel Core i5-12400F paired with the AMD Radeon RX 6600 delivers a mid-range 1080p experience in Lockdown Protocol, but the data reveals a system that struggles to maintain playable frame rates as resolution climbs to 4K. The combo ranks 1326th out of 1637 tested combinations, placing it in the lower 19% of all tested configs, a position driven primarily by the GPU's 8 GB VRAM capacity and the CPU's 6-core/12-thread configuration. Across all measured settings, the average frame rates range from a high of 145.6 FPS at 1080p Low to a low of 33.6 FPS at 4K Ultra, indicating a wide performance envelope that depends heavily on both resolution and quality preset.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial, and the pattern across settings reveals where the bottleneck shifts. At Low settings, the transition from 1920x1080 to 3840x2160 sees average FPS fall from 145.6 to 72.1, a reduction of 73.5 FPS or roughly 50%. At High settings, the drop is from 93.0 to 41.9 FPS, a 51.1 FPS decline that represents a 55% loss. The Medium preset follows a similar trajectory, falling from 101.4 to 48.5 FPS, while Ultra settings drop from 68.8 to 33.6 FPS, losing 35.2 FPS.

The scaling behavior suggests that at 1080p, the CPU still has headroom to push higher frame rates, as evidenced by the 145.6 FPS Low-settings result. However, the GPU's compute resources become the limiting factor as pixel count increases. The RX 6600's 1792 shading units and 64 ROPs, combined with its 224.0 GB/s memory bandwidth on a 128-bit bus, dictate that 4K resolution pushes the render pipeline to its limits. The 4K Ultra result of 33.6 FPS is particularly telling—this is below the 60 FPS threshold and indicates that the GPU is saturated.

Interestingly, the delta between Low and Ultra settings at each resolution remains relatively consistent in percentage terms. At 1080p, the gap between Low (145.6) and Ultra (68.8) is 76.8 FPS; at 1440p, it is 57.7 FPS (105.8 vs 48.1); at 4K, it narrows to 38.5 FPS (72.1 vs 33.6). This narrowing gap at higher resolutions confirms that the GPU becomes the dominant constraint, as the additional shading work from Ultra settings cannot be compensated by the CPU's ability to feed frames.

GPU Role

The AMD Radeon RX 6600, built on the RDNA 2.0 architecture with the Navi 23 chip, is the primary determinant of Lockdown Protocol's performance ceiling. The GPU's 8 GB of GDDR6 memory on a 128-bit bus provides 224.0 GB/s of bandwidth, which is adequate for 1080p and 1440p gameplay but becomes strained at 4K, particularly with higher texture quality settings that demand more VRAM capacity.

The clock behavior is notable: the GPU lists a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. The boost clock headroom of 865 MHz above base suggests that thermal and power conditions allow the card to operate near its maximum potential in less demanding scenes, but sustained loads at 4K will likely cause the clocks to settle closer to the game clock figure. The 14 Gbps effective memory speed translates to the 224.0 GB/s bandwidth, which is a moderate figure for a card in this class.

Benchmark data places the RX 6600 at the 69th percentile among all GPUs, with an average benchmark score of 25235. Its nearest rivals include the AMD Radeon 890M (deltaPct 0), the AMD Radeon RX 580 2048SP (deltaPct -0.2), the AMD Radeon RX 6700M (deltaPct 0.2), and the NVIDIA GeForce RTX 3060 Ti (deltaPct 0.5). The near-identical scores among these four GPUs indicate that Lockdown Protocol's performance is not exceptionally sensitive to GPU architectural differences within this performance band. The RX 6600's 8.928 TFLOPS FP32 throughput and 159.4 GPixel/s pixel rate are the raw compute figures that drive the measured FPS, and the 17.86 TFLOPS FP16 rate suggests that any half-precision optimizations in the game engine could provide additional headroom, though the measured results do not reflect such gains.

How This Combo Ranks

The combination of the Intel Core i5-12400F and AMD Radeon RX 6600 holds rank 1326 out of 1637 tested combos in Lockdown Protocol. This places the pairing in the bottom quintile of all tested systems, which is a meaningful indicator that this hardware configuration is not optimized for this game's demands. The rank reflects a system that can deliver smooth 1080p gameplay at lower settings but falls behind many other configurations at higher resolutions and quality presets.

The CPU's percentile ranking among all processors is 77, meaning it outperforms 77% of all CPUs in the database. However, this relative strength does not translate into a high combo rank, reinforcing that the GPU is the limiting factor. The GPU's percentile ranking of 69 is notably lower, and when combined with the game's measured FPS data, the result is a system that sits below the median of tested combos. The deltaPct values for the CPU's nearest rivals—Intel Core i7-8700K (0.1), Intel Core i5-1335U (0.3), AMD Ryzen 5 7533HS (-0.7), and AMD EPYC 7773X (1.3)—show that the i5-12400F is competitive with these processors on average benchmark scores, with a 19221 average against scores ranging from 18979 to 19364. This CPU-level competitiveness underscores that the combo's low rank stems from the GPU side of the equation.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values are 145.6 (Low), 101.4 (Medium), 93.0 (High), and 68.8 (Ultra). The Low preset delivers frame rates well above the 144 Hz refresh threshold, making it suitable for high-refresh monitors. Medium and High both clear 90 FPS, providing smooth gameplay, while Ultra dips to 68.8 FPS, which is still playable but approaches the 60 FPS boundary. The spread from Low to Ultra at 1080p is 76.8 FPS, indicating that quality settings have a substantial impact on performance at this resolution.

Moving to 2560x1440, the average FPS values are 105.8 (Low), 78.6 (Medium), 67.2 (High), and 48.1 (Ultra). The Low preset remains above 100 FPS, but Medium falls below the 80 FPS mark, and Ultra drops below 50 FPS. The 57.7 FPS spread between Low and Ultra is narrower than at 1080p, reflecting the GPU's increasing workload. For 1440p gaming, the data suggests that Medium settings are the practical ceiling for maintaining 60+ FPS, while High settings hover near the 60 FPS threshold and Ultra requires compromise.

At 3840x2160, the average FPS values are 72.1 (Low), 48.5 (Medium), 41.9 (High), and 33.6 (Ultra). Only the Low preset approaches playable frame rates, and even that falls short of 75 FPS. Medium and High are below 50 FPS, and Ultra is firmly in slideshow territory at 33.6 FPS. The 38.5 FPS spread from Low to Ultra at 4K is the smallest of the three resolutions, confirming that the GPU is the sole bottleneck and that even reducing quality settings cannot fully compensate for the pixel-pushing demands of 4K.

CPU Role

The Intel Core i5-12400F brings 6 cores and 12 threads to this combination, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. This Alder Lake-S architecture CPU, manufactured on Intel's 10 nm process, has 18 MB of shared L3 cache and supports both DDR4 and DDR5 memory. The CPU's benchmark scores are respectable: a Cinebench R23 multicore score of 16518, a Geekbench multicore score of 9138, and a 3DMark max threads score of 5912. These figures indicate that the CPU is not the primary constraint in Lockdown Protocol at most settings.

The CPU's 77th percentile ranking and its average benchmark score of 19221 place it nearly identically to the Intel Core i7-8700K (19210, deltaPct 0.1) and ahead of the Intel Core i5-1335U (19167, deltaPct 0.3), while trailing the AMD Ryzen 5 7533HS (19364, deltaPct -0.7) and the AMD EPYC 7773X (18979, deltaPct 1.3). In Lockdown Protocol, the 6-core/12-thread configuration is sufficient to drive the RX 6600 to its limits at 1080p, as evidenced by the 145.6 FPS Low-settings result. However, at 4K, the CPU's role diminishes, and the frame rates are dictated entirely by the GPU's rendering capabilities.

The CPU's 65 W TDP and locked multiplier (no overclocking) mean that sustained boost clock operation at 4.40 GHz is feasible within the power envelope, but the data does not suggest that CPU frequency is a limiting factor in this game. The single-threaded performance, as measured by a 3DMark single thread score of 909 and a Geekbench singlecore score of 2221, is adequate for the game's logic and physics, but the GPU-bound nature of Lockdown Protocol at higher resolutions means that CPU headroom is largely unused beyond 1080p. In summary, the i5-12400F provides a solid foundation, but the RX 6600's 8 GB VRAM and compute throughput cap the overall system performance, resulting in the observed combo rank of 1326 out of 1637.
