Lockdown Protocol

Lockdown Protocol is an FPS game released in March 2024, and this analysis covers the measured performance of the AMD Ryzen 5 8400F paired with the AMD Radeon RX 7600 across four graphical presets at three resolutions. All data presented here comes from direct measurements of average, minimum, and maximum FPS for this specific CPU–GPU combination, combined with synthetic benchmark scores from the CPU and GPU. The goal is to describe how this configuration scales with resolution, where its strengths and limitations lie, and which settings provide the most playable experience, using only the recorded numbers.

Resolution Scaling

The measured FPS for this combo decrease steadily as resolution increases from 1920x1080 to 3840x2160. At the Low preset, the average FPS falls from 160 at 1080p to 117 at 1440p and then to 76 at 4K. That is a 27% reduction from 1080p to 1440p and a further 35% reduction from 1440p to 4K – in absolute terms, a 44 FPS drop from the lowest to highest resolution. The Medium preset shows a similar pattern: 113 FPS at 1080p, 83 FPS at 1440p, and 54 FPS at 4K, dropping by roughly 59 FPS across the full range. High preset goes from 99 FPS at 1080p to 73 FPS at 1440p to 47 FPS at 4K, and Ultra starts at 74 FPS, falls to 54 FPS, then hits 35 FPS at 4K.

The data clearly indicate that the GPU is the limiting component at higher resolutions. At 1080p, even the most demanding Ultra preset yields 74 FPS, while the less demanding Low preset reaches 160 FPS. As resolution increases, the performance cost is nearly linear for each preset, and the frame time stress climbs quickly. For example, 4K Ultra delivers only 35 FPS, a value substantially below the 60 FPS threshold that most users would find acceptable. Despite the robust 6-core, 12-thread CPU with a 4.70 GHz boost clock, the frame rate at 4K is gated by the pixel load, not by the processor – the GPU simply runs out of headroom. Because the CPU metrics (cores, threads, clocks) remain constant at a given resolution, the resolution drop cannot be attributed to the processor but points directly to the graphics card’s processing capabilities and its 8 GB VRAM allocation.

How This Combo Ranks

Within the database of tested system combos, this particular combination of Ryzen 5 8400F and RX 7600 is ranked 2577 out of 3714 total configurations for Lockdown Protocol. That means it sits slightly below the median – roughly 31% of tested combos perform better, and about 69% perform worse. The CPU alone ranks in the 77th percentile among all CPUs, while the GPU ranks in the 57th percentile among GPUs. These benchmark positions suggest the CPU is a relatively strong unit for its class, with a multi-core score of 20851 in Cinebench R23 and a single-core score of 2943, both well above the average processor. The GPU, by contrast, is typical for its tier, with an average benchmark score of 15169 and a PassMark G3D score of 16634. The combined ranking in Lockdown Protocol is notably lower than the CPU’s individual percentile, which tells a clear story: the GPU is mostly pulling the system down in this game.

The nearest CPU rivals for the Ryzen 5 8400F – AMD Ryzen 5 7500F (score 24964, delta 0.2%), Intel Core i7-11850H (24935, delta 0.3%), Intel Core i7-13620H (24911, delta 0.4%), and AMD EPYC 9474F (25103, delta -0.4%) – all have average benchmark scores within a few tenths of a percent. So in synthetic tests, the CPU is essentially on par with those alternatives. But in Lockdown Protocol, the difference between a 77th-percentile CPU and a 57th-percentile GPU becomes meaningful, because the game is visually heavy. The low combined rank (2577/3714) should not be read as a CPU fault; rather, it reflects the fact that the CPU’s capability is underutilized in scenarios where the GPU is already maxed out. In short, the data indicate that the combo sits in the lower third of all tested systems for this title, a strong contributor to the low rank.

GPU Role

The AMD Radeon RX 7600, built on the RDNA 3.0 architecture with a Navi 33 die, is the performance bedrock of this pair. Its specification sheet includes 8 GB of GDDR6 memory on a 128-bit bus with a bandwidth of 288.0 GB/s, base clock of 1720 MHz, game clock of 2250 MHz, and boost clock of 2655 MHz. The shading unit count is 2048, with 128 texture units, 64 ROPs, and 32 ray-tracing cores. In terms of synthetic benchmarks, it yields a 3DMark Steel Nomad DX12 score of 6072 (actually 2310? Wait the pack says 2310), a 3DMark Steel Nomad DX12 score of 2310, and Geekbench OpenCL score of 88051, Vulkan score of 34401. Its PassMark G3D score is 16634, with a percentile of 57 among all GPUs.

The GPU’s role in Lockdown Protocol becomes clear when we cross-reference the measured FPS with its specifications. At 4K Ultra, the frame rate plummets to 35 FPS, which aligns with the GPU’s memory bandwidth and shading capacity. 8 GB of VRAM is often borderline for 4K gaming, and the measured results support that idea, even though the data do not explicitly include VRAM usage. The GPU’s 128-bit bus means bandwidth is limited, and its 2048 shader units must handle the high pixel load. More telling is the jump from 4K Medium 54 FPS to 4K Low 76 FPS – a 22 FPS improvement when texture quality is reduced. That indicates that the GPU’s compute units are not the sole bottleneck; the memory subsystem and bandwidth limitations become more noticeable at lower settings.

From benchmark scores, the RX 7600 sits in the lower half of the overall GPU distribution. Its nearest rivals are NVIDIA GeForce RTX 3050 OEM (delta -0.2%), AMD Radeon Pro 560X (0.6% slower), AMD Radeon 680M (-0.7% slower), and NVIDIA GeForce GTX 660 Ti (0.7% slower). The 0.7% delta from the fastest of those rivals (like RTX 3050 OEM) is still negligible in synthetic tests, but in real titles the differences expand. In Lockdown Protocol, the 57th percentile ranking of the GPU is directly visible in the 4K Ultra frame rate of 35 FPS, which is far below the. It is clear that the RX 7600 is not a 4K-class card, yet at 1080p and 1440p it provides playable numbers, especially at Medium or Low settings.

FAQ

A: The measured average FPS at 2560x1440 on Ultra is 73 FPS. The minimum is not recorded, but the average is exactly 73 FPS.

Q: Which resolution touches the highest FPS for this system?

A: The highest average FPS is 160, achieved at 1920x1080 with Low settings. Even the High preset at 1080p yields 99 FPS.

Q: How does the CPU's multi-core score compare to the nearest rival?

A: The Ryzen 5 8400F scores 20851 in Cinebench R23, while the AMD Ryzen 5 7500F has an average multi-score of 24964 – a 0.2% higher score. The Intel Core i7-11850H is 0.3% higher, and the AMD EPYC 9474F is -0.4% lower.

Q: What is the launch MSRP of each part?

A: The AMD Ryzen 5 8400F has a launch MSRP of $170, and the AMD Radeon RX 7600 has a launch MSRP of 269 USD.

Q: Can the RX 7600 provide smooth gameplay at 4K?

A: Only at the Low setting does it reach an average FPS of 76. Medium obtains 54 FPS, High 47 FPS, and Ultra 35 FPS. All of those except Low fall below the common 60 FPS target, so the answer is no based on the measured data.

Q: How does the 8400F single-core score relate to its overall performance in this game?

A: The CPU’s single-core score of 2943 in Cinebench R23 places it in the 84th percentile, which shows that its own per-thread capability is strong. But in Lockdown Protocol, at 1080p Low the CPU can handle 160 FPS, indicating that single-thread performance is likely sufficient for most playable presets.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on Zen 4 (Phoenix) on the 4nm node. It carries a base clock of 4.20 GHz, a boost to 4.70 GHz, 1 MB L2 per core and a 16 MB shared L3 cache, running on the Desktop platform with a 65 W TDP. In synthetic benchmarks, it scores 20951 in Cinebench R23 multicore and 2943 in single-core, with a PassMark single-thread score of 3685 and a multithread score of 24389. All of these numbers are in the 84th percentile of all CPUs, which indicates that as a standalone piece, the CPU is strong.

In Lockdown Protocol, however, the measured FPS progression across resolutions shows no evidence that the CPU becomes a limitation. At 1080p Low, the 160 FPS result is the highest within this combination, yet it jumps to 117 FPS at 1440p and to 76 FPS at 4K for the same preset. That linear scaling is typical of GPU-bound rendering, not a CPU-bound scenario. For a CPU to be the primary issue, you would expect minimal FPS change when the resolution rises since the geometry and game logic logic stay constant. But the frame rate halves from 1080p to 4K, so the CPU is not the wall here. Instead, the game takes advantage of the CPU’s six cores and twelve threads; Lockdown Protocol is an FPS with many dynamic objects, but even in the most demanding Ultra preset, the 35 FPS at 4K is produced by the GPU’s pixel throughput constraints, not by insufficient CPU threads.

The nearest CPU rivals – Ryzen 5 7500F, i7-11850H, i7-13620H, and EPYC 9474F – all show scores within 0.4% of the 8400F, so at the CPU level no standout issue appears. Because these six parts perform almost identically in benchmarks, the total system percentile is not influenced by CPU variance. The same CPU with a faster GPU would obviously rank higher in Lockdown Protocol, confirming that its role in this combo is to feed a mid-range GPU without impeding it at 1080p and 1440p, but at 4K the GPU is the choke point.

Settings Recommendations

Based on the measured frames, the best settings depend heavily on the display resolution needed Web user.

At 1920x1080: The Low preset hits 160 FPS, which is excellent for esports or high-refresh (above 144 Hz). Medium reaches 113 FPS and High 99 FPS, both well north of 60. Ultra yields 74 FPS, still highly smooth. For the most competitive or high-Hz panel, choose Low to get the highest headroom. For a typical 60 FPS or slightly higher, High or Ultra is best since visual quality is good enough – there is no FPS problem below 60.

At 2560x1440: Medium gives 83 FPS – a sweet spot that balances visual fidelity and speed. High gives 79 FPS (actually 73 FPS), Low gives 117 FPS, and Ultra only 57 FPS. The difference between Medium and Low is 30% increase in FPS, which could be key for 144 Hz monitors. For a static 1440p60 panel, Medium or High is recommended. If a higher refresh rate is present, Low avoids the ultra cost and is still 67 FPS above the 60 FPS floor.

At 3840x2160: only the Low preset meets the 60 FPS target with 76 FPS. Medium (57 FPS) is very close but does not hold 60. High (47) and Ultra (35) are below the playable threshold for most users. Therefore, the best experience on a 4K display is at Low settings. There is no tuning that will bring Medium up; the resolution is simply too demanding for this GPU.

Measured FPS Breakdown

All measured FPS values from the dataset are as follows, for quick reference:

| Resolution | Preset | Average (FPS) | Minimum (FPS) | Maximum (FPS) |

|---|---|---|---|---|

| 1920x1080 | Low | 160 | – | – |

| 1920x1080 | Medium | 113 | 96 | 130 |

| 1920x1080 | High | 99 | – | – |

| 1920x1080 | Ultra | 74 | – | – |

| 2560x1440 | Low | 117 | – | – |

| 2560x1440 | Medium | 83 | 71 | 96 |

| 2560x1440 | High | 73 – | – | – |

| 2560x1440 | Ultra | 54 | – | – |

| 3840x2160 | Low | 76 | – | – |

| 3840x2160 | Medium | 54 | 46 | 62 |

| 3840x2160 | High | 47 | – | – |

| 3840x2160 | Ultra | 35 | – | – |

The data only contain min/max values for the Medium preset at each resolution. For other presets only the average is given. This means that the variance across other presets is not recorded, but the Medium rows show the typical spread: at 1080p the min and max are 141 FPS apart? Actually 130 minus 96 is 34 FPS. At 1440p that gap is 25 FPS (96-71), and at 4K the gap is 16 FPS (62-46). The smaller variance at higher resolutions is predictable as the frame rate drops and the GPU often becomes the limiting factor. Overall, this table essentially defines the capabilities of the RX 7600 and the 8400F in Lockdown Protocol, meaning that any preset above Low at 4K pushes beyond that card’s realism.
