Lockdown Protocol

Measured FPS Breakdown

The recorded data for Lockdown Protocol with the Intel Core i5-9400 and AMD Radeon RX 6600 XT shows a clear performance hierarchy across resolutions and presets. At 1920x1080, the combination delivers its strongest results. The Low preset reaches an average of 159 FPS, the highest figure recorded for this pairing. Medium averages 113 FPS with a minimum of 96 FPS and a maximum of 130 FPS. High drops to 99 FPS average, while Ultra settles at 74 FPS average. All four 1080p presets stay comfortably above the 60 FPS playable threshold.

Moving to 2560x1440, the averages step down but remain respectable. Low produces 117 FPS average, Medium hits 83 FPS with a min/max range of 70 to 95, and High manages 72 FPS average. Ultra falls to 54 FPS average, which dips below the 60 FPS threshold. The gap between Low and High at 1440p is 45 FPS, a substantial spread that indicates the GPU is responsive to preset changes.

At 3840x2160, the picture changes significantly. Low still achieves 75 FPS average, making it the only 4K preset that clears 60 FPS. Medium averages 53 FPS with a minimum of 45 FPS and a maximum of 61 FPS. High drops to 47 FPS average, and Ultra bottoms out at 35 FPS average. The 4K results show a steep falloff as settings increase, with a 40 FPS difference between Low and Ultra.

The data indicates that min/max figures were only recorded for the Medium preset at each resolution. At 1080p Medium, the frame time consistency is solid, with the minimum staying 17 FPS above the playable threshold. At 1440p Medium, the minimum of 70 FPS still clears 60 FPS. At 4K Medium, the minimum of 45 FPS falls well short, confirming that this preset is not viable at that resolution.

CPU and GPU Roles

The scaling between resolutions reveals how the Core i5-9400 and RX 6600 XT share the workload in Lockdown Protocol. From 1080p to 1440p, the average FPS drops by roughly 25 to 30 percent across presets. From 1440p to 4K, the drop is steeper, around 35 to 40 percent. This pattern suggests that at 1080p, the CPU has more influence on the final frame rate, while at 4K, the GPU becomes the dominant constraint.

The i5-9400 is a 6-core, 6-thread processor with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. Its Cinebench R23 multi-core score is 6629, and its single-core score is 935. The CPU sits at the 47th percentile among all tested processors, which is a mid-pack position. In Lockdown Protocol, the 1080p Low result of 159 FPS shows that the CPU can feed the GPU enough frames at lower settings, but the 4K Ultra result of 35 FPS indicates the GPU is the limiting factor at high resolution and maxed presets.

The RX 6600 XT features 2048 shading units, 128 texture units, and 64 ROPs. Its boost clock reaches 2589 MHz, and it has 8 GB of GDDR6 memory on a 128-bit bus with 256.0 GB/s bandwidth. The GPU sits at the 70th percentile among all tested GPUs, which is a stronger relative position than the CPU. At 4K, the GPU's raw throughput becomes the bottleneck, as evidenced by the 47 FPS average at High and 35 FPS at Ultra. At 1080p, the CPU's mid-pack standing is less exposed, since the GPU can still hit 159 FPS at Low.

The preset scaling also tells a story. At 1080p, going from Low to Ultra costs 85 FPS, a 53 percent reduction. At 4K, the same preset jump costs 40 FPS, a 53 percent reduction as well. The proportional impact is similar, but the absolute numbers are much lower at 4K. This indicates that the combination is balanced enough at 1080p to let settings dictate the experience, while at 4K, even Low settings push the hardware to its limits.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU, the Intel Core i5-9400 has an average benchmark score of 2254. The closest match is the Intel Core i7-1068NG7 with an average score of 2259, a delta of -0.2 percent. The Intel Core i7-10710U scores 2248, a delta of 0.3 percent. The AMD Ryzen 5 PRO 1500 scores 2246, a delta of 0.4 percent. The Intel Core i3-10305 scores 2264, a delta of -0.4 percent. All four rivals sit within a 1 percent band of the i5-9400, meaning any of these processors would produce nearly identical frame rates in Lockdown Protocol when paired with the same GPU.

For the GPU, the AMD Radeon RX 6600 XT has an average benchmark score of 24442. The NVIDIA GeForce GTX 1630 scores 24277, a delta of 0.7 percent. The Intel Arc A350M scores 24647, a delta of -0.8 percent. The NVIDIA GeForce GTX 780 Ti scores 24236, a delta of 0.8 percent. The NVIDIA GeForce RTX 2080 SUPER scores 24170, a delta of 1.1 percent. These four GPUs are all within 2 percent of the RX 6600 XT's average score, so swapping to any of them would yield similar performance in this game.

In practical terms, a system with the i5-9400 and RX 6600 XT would behave almost identically to one with a Core i7-1068NG7 or a Core i3-10305 paired with the same GPU. On the graphics side, the GTX 1630 or RTX 2080 SUPER would produce comparable results when paired with the i5-9400. The delta percentages are small enough that the playable resolutions and presets would remain the same: 1080p at all settings, 1440p up to High, and 4K only at Low.

How This Combo Ranks

The combination of the Intel Core i5-9400 and AMD Radeon RX 6600 XT ranks 2630 out of 3714 tested combos in Lockdown Protocol. This places it in the lower 30 percent of all pairings in the database. The rank reflects the mid-pack CPU and the above-average GPU working together, but the CPU's 47th percentile standing drags the overall position down relative to combos with newer or higher-end processors.

The rank of 2630 means that roughly 1100 tested combinations perform worse than this pairing, while about 2600 perform better. That is a meaningful context for the measured FPS results. The 1080p performance is strong, with all presets clearing 60 FPS, but the 4K results are limited to Low settings. The combo's rank suggests that many other systems can handle higher settings at 1440p or 4K, which is consistent with the 4K High average of 47 FPS falling short of the playable threshold.

The GPU's 70th percentile ranking is the stronger component here. The CPU's 47th percentile is the weaker link. In a game like Lockdown Protocol, which appears to scale well with both CPU and GPU based on the resolution and preset differences, this imbalance means the CPU limits the system's potential at lower resolutions, while the GPU limits it at higher resolutions. The net effect is a combo that is solidly capable at 1080p, acceptable at 1440p with tuned settings, and only marginally playable at 4K.

The Verdict

Can this PC run Lockdown Protocol? Yes, but the answer depends heavily on resolution and settings. The verdict by resolution is clear from the measured data.

At 1920x1080, all four presets are playable. The best setting is Ultra with an average of 74 FPS, which clears the 60 FPS threshold by 14 frames. Low delivers 159 FPS, Medium 113 FPS, and High 99 FPS. For a 1080p display, this combination offers full flexibility, and players can choose between maximum visual quality at 74 FPS or competitive frame rates at 159 FPS.

At 2560x1440, three presets are playable: High at 72 FPS, Low at 117 FPS, and Medium at 83 FPS. The best setting is High with an average of 72 FPS. Ultra falls to 54 FPS, which misses the 60 FPS threshold. Players with 1440p monitors should stick to High or below for a smooth experience.

At 3840x2160, only Low is playable, with an average of 75 FPS. Medium averages 53 FPS, High 47 FPS, and Ultra 35 FPS. The best setting at 4K is Low, which still provides a comfortable margin above 60 FPS. Players with 4K displays will need to accept reduced visual quality to maintain playable frame rates.

The playable threshold is 60 FPS, and the data shows that this combo clears it at 1080p across the board, at 1440p for three of four presets, and at 4K for only the Low preset. The system is best suited for 1080p gaming with high settings, or 1440p gaming with High settings. It is not a 4K-capable machine beyond Low presets.
