Lockdown Protocol

# Lockdown Protocol with AMD Ryzen 5 8400F + NVIDIA GeForce RTX 5090 D

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 5090 D delivers a formidable Lockdown Protocol experience, with measured frame rates ranging from 88 FPS at 4K Ultra to 290 FPS at 1080p Low. This combination sits at rank 48 out of 2,828 tested combos, placing it firmly in the top 2% of all configurations tested for this FPS title. The data reveals a system that scales predictably across resolutions and settings, though the pattern of scaling exposes where each component's influence begins and ends.

Resolution Scaling

The measured FPS data shows a clear and consistent pattern of performance degradation as resolution increases, but the rate of that degradation tells an important story about system balance. At 1080p High, the combo produces 243 FPS average; at 1440p High, that drops to 183 FPS; and at 4K High, it falls further to 118 FPS. This represents a 24.7% drop from 1080p to 1440p, followed by a 35.5% drop from 1440p to 4K. The scaling is not linear — the steepest percentage decline occurs in the final step to 4K, which is characteristic of a system where the GPU becomes progressively more dominant as pixel count rises.

Looking at Low settings, the same pattern emerges with higher absolute numbers: 290 FPS at 1080p, 261 FPS at 1440p, and 190 FPS at 4K. The percentage drops are 10.0% and 27.2% respectively. The relatively modest decline from 1080p to 1440p at Low settings suggests that at lower graphical loads, the CPU is still contributing meaningfully to frame generation. However, the much larger drop when moving to 4K Low indicates the GPU's fill rate and memory bandwidth are becoming the binding constraints.

The Medium settings data includes min and max FPS figures, providing additional insight. At 1080p Medium, the average is 255 FPS with a minimum of 217 and maximum of 293. At 1440p Medium, the average drops to 209 FPS with min/max of 178/241. At 4K Medium, the average is 135 FPS with min/max of 115/155. The spread between minimum and maximum FPS (roughly 30% of the average at each resolution) suggests frame time variance that remains relatively consistent regardless of resolution, pointing toward a CPU-side component in frame pacing rather than purely GPU-bound rendering.

Ultra settings show the heaviest load: 187 FPS at 1080p, 137 FPS at 1440p, and 88 FPS at 4K. The 4K Ultra result is the only measured configuration below 100 FPS, indicating that this is the threshold where the RTX 5090 D's immense compute resources are finally saturated by Lockdown Protocol's demands. The resolution scaling data collectively indicates that at 1080p and 1440p, the system has headroom in the GPU, while at 4K, particularly with Ultra settings, the GPU becomes the clear limiting component.

GPU Role

The NVIDIA GeForce RTX 5090 D is built on the Blackwell 2.0 architecture using TSMC's 5 nm process, packing 92,200 million transistors into a 750 mm² die. Its 32 GB of GDDR7 memory across a 512-bit bus delivers 1.79 TB/s of bandwidth, which is substantial for a game like Lockdown Protocol that demands rapid texture streaming and high-resolution asset access. The GPU's clock behavior shows a base of 2017 MHz with a boost of 2407 MHz, and memory running at 1750 MHz (28 Gbps effective). These specifications translate to a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s, with FP32 compute at 104.8 TFLOPS.

In the benchmark data, the RTX 5090 D achieves a Passmark G3D score of 44,065 and a 3DMark Steel Nomad DX12 score of 14,326, with a Geekbench Vulkan score of 376,915. Its percentile ranking among all GPUs is 92, and its average benchmark score of 77,712 places it slightly above the AMD Radeon RX 6650M XT (76,904, a 1.1% delta) and slightly below the AMD Radeon RX 6850M XT (78,940, a -1.6% delta). The nearest rival comparisons show that the RTX 5090 D sits in a competitive band with those mobile-class Radeon parts, which is notable given its desktop flagship positioning.

The GPU's role in Lockdown Protocol becomes apparent when examining the measured FPS across settings. At 1080p Low, the 290 FPS result is likely near the practical ceiling for the engine, and the fact that Ultra settings at 1080p still achieve 187 FPS suggests the GPU has ample compute headroom at lower resolutions. The 32 GB VRAM capacity is more than sufficient for any settings combination in this game, and the 1.79 TB/s bandwidth ensures that even at 4K Ultra, memory throughput does not become a bottleneck. The 4K Ultra result of 88 FPS, while the lowest in the dataset, still represents playable performance and showcases the GPU's ability to handle the most demanding configuration tested.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 (Phoenix) architecture, manufactured on TSMC's 4 nm process. It operates with a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The CPU supports DDR5 memory in dual-channel configuration with 83.2 GB/s of bandwidth, and its cache hierarchy includes 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. This is a desktop AM5 part with PCIe Gen 4 support (20 lanes from CPU), and it was released with a launch MSRP of $170.

In synthetic benchmarks, the 8400F shows strong multi-threaded performance: Cinebench R23 multicore scores 20,851, while single-core reaches 2,943. Passmark multithread scores 24,389, with single-thread at 3,685. The 3DMark results show scaling from 1,874 in the 2-thread test to 6,165 in max-threads, indicating reasonable multi-core scaling for a 6-core part. The CPU's percentile ranking among all CPUs is 77, with an average benchmark score of 25,005. Its nearest rivals are remarkably close: the AMD Ryzen 5 7500F scores 24,964 (0.2% delta), the Intel Core i7-11850H scores 24,935 (0.3% delta), and the Intel Core i7-13620H scores 24,911 (0.4% delta). The AMD EPYC 9474F scores 25,103 (-0.4% delta), completing a tightly clustered competitive set.

For Lockdown Protocol, the CPU's influence is most evident in the lower-resolution and lower-settings scenarios. At 1080p Low, the 290 FPS result likely approaches the engine's frame rate cap or the CPU's ability to feed draw calls to the GPU. The 6-core/12-thread configuration with boost clocks up to 4.70 GHz provides sufficient single-thread performance for game logic and physics, while the 16 MB L3 cache helps with frequently accessed game data. The 83.2 GB/s memory bandwidth is adequate for feeding the GPU at high frame rates, though the 4K results show that this is not the primary constraint. The CPU's 77th percentile ranking indicates it is a solid mid-range performer, and in this combo, it does not appear to be the limiting component at 4K, where GPU load dominates.

Measured FPS Breakdown

The measured FPS data for this combo covers 12 distinct configurations across three resolutions and four quality settings. At 1920x1080, the results are: Low averages 290 FPS, Medium averages 255 FPS (min 217, max 293), High averages 243 FPS, and Ultra averages 187 FPS. The progression from Low to Ultra shows a 35.5% reduction in average FPS, with the largest single-step drop occurring between High and Ultra (56 FPS). The Medium setting's minimum of 217 FPS is the lowest 1080p figure recorded, which is still well above typical high-refresh-rate monitor capabilities.

At 2560x1440, the performance scales down predictably: Low averages 261 FPS, Medium averages 209 FPS (min 178, max 241), High averages 183 FPS, and Ultra averages 137 FPS. The drop from 1080p to 1440p is consistent across settings, ranging from 10.0% at Low to 26.7% at Ultra. The Medium setting's min/max spread of 63 FPS (178 to 241) is the widest recorded at any resolution, suggesting occasional frame dips that could be noticeable on a 240 Hz display. The 1440p Ultra result of 137 FPS remains highly playable for competitive FPS gameplay.

At 3840x2160, the data shows the system's limits: Low averages 190 FPS, Medium averages 135 FPS (min 115, max 155), High averages 118 FPS, and Ultra averages 88 FPS. The 4K Low result of 190 FPS demonstrates that even at the highest resolution, the system can deliver high refresh rates when graphical load is reduced. However, the 4K Ultra result of 88 FPS is the only configuration below 100 FPS, and it represents a 53.8% reduction from 1080p Ultra. The Medium setting at 4K shows a min of 115 FPS, meaning the lowest recorded frame rate across all tests is still above 100 FPS except for the 4K Ultra average.

The data reveals that this combo is capable of high refresh rates at 1080p and 1440p across all settings, with only 4K Ultra falling below the 100 FPS threshold. The Medium settings with min/max data show that frame pacing is generally stable, with the widest variance occurring at 1440p Medium.

How This Combo Ranks

The AMD Ryzen 5 8400F + NVIDIA GeForce RTX 5090 D combination achieves rank 48 out of 2,828 tested combos in Lockdown Protocol. This places it in the 98.3rd percentile — meaning it outperforms approximately 2,780 other tested configurations. The ranking reflects the raw GPU power of the RTX 5090 D (92nd percentile among all GPUs) combined with a mid-range CPU (77th percentile among all CPUs). The high combo rank relative to the CPU's individual percentile suggests that Lockdown Protocol is predominantly GPU-bound in most configurations, allowing the RTX 5090 D to carry the system toward the top of the rankings.

The gap between the CPU's 77th percentile and the combo's 98.3rd percentile ranking indicates that the game's performance ceiling is largely determined by the GPU. The RTX 5090 D's nearest rivals in synthetic benchmarks — the AMD Radeon RX 6650M XT and RX 6850M XT — show deltas of 1.1% and -1.6% respectively, meaning the 5090 D sits in a tightly contested performance band despite its flagship positioning. This further suggests that in Lockdown Protocol, the GPU's real-world performance is what matters most, and the 5090 D delivers near-top-tier results.

The combo rank of 48 out of 2,828 also implies that 47 other combinations achieve higher frame rates in this game. These would likely pair even higher-end CPUs with the RTX 5090 D or similar flagship GPUs, potentially eliminating any CPU-side bottlenecks that might exist at 1080p Low where the 8400F's 290 FPS result could be constrained by processor throughput. The data indicates that for most users, this combo delivers performance at or near the top of what is achievable, with only a small fraction of exotic configurations surpassing it.
