Performance Analysis: Lockdown Protocol on Your System
Lockdown Protocol, a first-person shooter released on 2024-03-11, requires sustained frame rates to keep its action readable. The database includes measured average frame rates for the Intel Core i5-9400 paired with the AMD Radeon RX 7800 XT across three resolutions (1920x1080, 2560x1440, 3840x2160) and four quality presets (Low, Medium, High, Ultra). Minimum and maximum frame rates were not recorded for this combination, so the analysis relies on average FPS. The i5-9400 is a 6-core 6-thread Coffee Lake desktop processor released in 2018, while the RX 7800 XT is a 2023 RDNA 3.0 card built on the Navi 32 chip.
Measured FPS Breakdown
At 1920x1080, the combo produces 164.7 FPS on Low, 145.2 FPS on Medium, 137.3 FPS on High, and 108 FPS on Ultra. All four presets clear the 60 FPS playable threshold with considerable margin. The ordering is monotonic: each step up in quality costs a measurable amount of average frame rate, but even Ultra retains a triple-digit result. This resolution is clearly the strongest environment for this pairing.
At 2560x1440, the averages are 150.1 FPS on Low, 122.9 FPS on Medium, 109.1 FPS on High, and 79.9 FPS on Ultra. Again, every preset stays above 60 FPS. The Ultra preset at 1440p is the first to dip below 100 FPS, but it remains comfortably playable. The step from High to Ultra at this resolution is significant, dropping from 109.1 to 79.9.
At 3840x2160, the averages are 114 FPS on Low, 80.5 FPS on Medium, 70.3 FPS on High, and 52.1 FPS on Ultra. The Ultra preset falls below the 60 FPS threshold, making it the only unplayable setting in the dataset. High remains playable at 70.3 FPS, and Low is remarkably strong at 114 FPS given the 4K resolution. The spread between Low and Ultra at 4K is large, from 114 down to 52.1.
The data shows a consistent pattern: the RX 7800 XT has enough headroom at 1080p and 1440p to run all presets smoothly, but 4K Ultra exceeds its practical limit with this CPU.
Best Settings per Resolution
At 3840x2160, the most demanding preset that stays at or above 60 FPS is High, with an average of 70.3 FPS. Ultra misses the threshold at 52.1 FPS. Medium at 80.5 FPS and Low at 114 FPS are also viable, but High offers the best visual quality within the playable envelope.
At 2560x1440, Ultra is the best setting, averaging 79.9 FPS. Since all presets are playable at this resolution, there is no reason to drop below Ultra unless the user prefers higher frame rates for competitive play.
At 1920x1080, Ultra averages 108 FPS, making it the best setting. The 60 FPS threshold is exceeded by a wide margin, so the highest quality preset is also the recommended one.
How This Combo Ranks
In the database, this CPU and GPU combination ranks 1556th out of 3714 tested combinations for Lockdown Protocol. This places it in the upper portion of the tested field. The Intel Core i5-9400 has a percentile ranking of 47 among all CPUs, meaning it sits just below the median. The AMD Radeon RX 7800 XT has a percentile ranking of 51 among all GPUs, just above the median. The combo's overall rank of 1556 reflects the pairing of a slightly below-average CPU with a slightly above-average GPU.
Similar Performance Alternatives
For the CPU, the nearest rivals by average benchmark score are the Intel Core i7-1068NG7 (delta -0.2%), the Intel Core i7-10710U (delta 0.3%), the AMD Ryzen 5 PRO 1500 (delta 0.4%), and the Intel Core i3-10305 (delta -0.4%). All four are within 0.4% of the i5-9400's average score of 2254. In CPU-bound scenarios, such as 1080p Low, swapping to any of these chips would produce nearly identical frame rates. The i5-9400's own Cinebench R23 multicore score is 6629 and singlecore is 935, while its Geekbench multicore is 5141 and singlecore is 1389.
For the GPU, the nearest rivals are the NVIDIA GeForce GTX 1660 (delta -0.5%), the AMD Radeon Pro 5500M (delta 0.9%), the NVIDIA Tesla K20c (delta 1.3%), and the AMD Radeon RX 6500 XT (delta -1.8%). The GTX 1660 is the closest at -0.5% of the RX 7800 XT's average score of 11627. In GPU-bound scenarios, such as 4K Ultra, these alternatives would land within a similar performance envelope. The RX 7800 XT's own 3DMark Steel Nomad score is 4157, and its PassMark G3D score is 24176.
CPU and GPU Roles
The scaling data reveals which component dominates at each resolution. At Low settings, the average FPS moves from 164.7 at 1080p to 150.1 at 1440p and then to 114 at 4K. The modest decline between 1080p and 1440p at Low settings suggests the CPU is the limiting factor at lower resolutions, because the GPU is not yet saturated. At Ultra settings, the averages move from 108 at 1080p to 79.9 at 1440p and then to 52.1 at 4K. The sharper decline at Ultra indicates the GPU becomes the primary bottleneck as both resolution and settings increase.
The i5-9400 has 6 cores and 6 threads, with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. It uses 9 MB of shared L3 cache and dual-channel DDR4 memory with 42.7 GB/s of bandwidth. This is a mainstream 2018 desktop configuration. The RX 7800 XT is a 2023 GPU with 3840 shading units, 240 texture mapping units, 96 ROPs, and 60 ray tracing cores. It has 16 GB of GDDR6 memory on a 256-bit bus, providing 624.1 GB/s of bandwidth. The GPU's boost clock is 2430 MHz and its game clock is 2124 MHz. Its launch MSRP was 499 USD.
The CPU has a 65 W TDP, while the GPU has a 263 W TDP and a suggested power supply of 600 W. The GPU is a dual-slot card with 2x 8-pin power connectors.
At 1080p Low, the 164.7 FPS average is likely near the CPU's ceiling for this game. The i5-9400's 47th percentile ranking among all CPUs supports this interpretation. At 4K Ultra, the 52.1 FPS average shows the GPU struggling with the combined load of high resolution and high settings. The component roles are clear: the CPU matters more at low settings and low resolutions, while the GPU dominates at high settings and high resolutions. For users targeting 1440p or 4K, the RX 7800 XT is the more important component; for 1080p esports-style play, the i5-9400 is the limiting factor.
The Verdict
This PC can run Lockdown Protocol at 60 FPS or higher across all three tested resolutions with the appropriate preset. At 3840x2160, the playable settings are High, Medium, and Low, with High being the best at 70.3 FPS. At 2560x1440, all four settings are playable, and Ultra is the best at 79.9 FPS. At 1920x1080, all four settings are playable, and Ultra is the best at 108 FPS. The only preset that fails the 60 FPS threshold is 4K Ultra at 52.1 FPS. Users with a 4K display should choose High settings, while 1440p and 1080p users can max out the game without concern.
