Lockdown Protocol

The AMD Ryzen 5 8400F and Intel Arc B570 combination delivers a playable Lockdown Protocol experience at 1080p and 1440p, but struggles at 4K unless settings are dropped significantly. Benchmark data shows this pairing ranks 2987th out of 3714 tested combinations, placing it in the lower-middle tier of systems for this specific title. The measured frame rates reveal a system that is perfectly capable for mainstream gaming, with clear performance scaling as resolution drops and settings are tuned.

Measured FPS Breakdown

At 3840x2160, the system produces an average of 40 FPS on High settings, which falls well below the 60 FPS playability threshold. Dropping to Medium improves the average to 46 FPS, with a minimum of 39 FPS and a maximum of 52 FPS, still not reaching smooth gameplay. Low settings are the only playable option at 4K, delivering an average of 64 FPS. Ultra settings at this resolution are the most demanding, yielding an average of just 30 FPS.

Moving to 2560x1440 shows a substantial improvement. High settings achieve an average of 62 FPS, just clearing the 60 FPS bar. Medium settings run at an average of 71 FPS, with a minimum of 60 FPS and a maximum of 81 FPS, providing a consistently smooth experience. Low settings hit an average of 100 FPS, which is excellent for competitive play. Ultra settings at 1440p average 46 FPS, which remains below the playability threshold.

At 1920x1080, the system demonstrates its full potential. Ultra settings reach an average of 63 FPS, making the highest preset playable at this resolution. High settings average 84 FPS, Medium averages 96 FPS with a minimum of 82 FPS and a maximum of 111 FPS, and Low settings hit an impressive 136 FPS. The gap between Low and Ultra at 1080p is 73 FPS, showing that the game scales well with settings while still maintaining playability even at maximum quality.

CPU and GPU Roles

The performance scaling across resolutions indicates that the Intel Arc B570 becomes the limiting factor as resolution increases. At 1080p, the CPU has more headroom, allowing the GPU to push higher frame rates — the jump from 63 FPS at Ultra to 136 FPS at Low represents a 116% improvement that is primarily GPU-bound. The Ryzen 5 8400F, with its six cores and twelve threads based on Zen 4 architecture, provides sufficient processing power for this game at lower resolutions.

At 1440p, the balance shifts. The difference between Low and Ultra narrows to 54 FPS, indicating the GPU is beginning to bottleneck. The 8400F's single-thread performance, scoring 2943 in Cinebench R23 single-core, is adequate for the game's logic, but the Arc B570's 11.52 TFLOPS of FP32 compute is the constraining factor. The 160-bit memory bus and 380.0 GB/s bandwidth also play a role, as higher resolutions demand more memory throughput.

At 4K, the GPU dominance is absolute. The system cannot maintain 60 FPS on Medium or High settings, with only Low settings crossing the threshold. The Arc B570's 10 GB of GDDR6 memory is sufficient for this game, but the raw compute power is insufficient for high-fidelity 4K rendering. The CPU's role diminishes further, as the frame rates are consistently below the playable threshold regardless of the 8400F's capabilities.

Similar Performance Alternatives

The Ryzen 5 8400F sits very close to several other processors in benchmark performance. The AMD Ryzen 5 7500F is nearly identical, with an average score of 24964 compared to the 8400F's 25005, a delta of just 0.2%. This means either CPU would produce nearly identical frame rates in Lockdown Protocol. The Intel Core i7-11850H and Intel Core i7-13620H are also within 0.4% of the 8400F's average score, though these are mobile processors that would behave differently in sustained workloads.

On the GPU side, the Intel Arc B570's nearest rival is the Intel Arc A750, which scores 20582 versus the B570's 20556, a delta of -0.1%. This suggests the A750 would deliver essentially the same performance in this game. The NVIDIA GeForce RTX 3070 Mobile scores 20534, within 0.1% of the B570, though as a mobile part its power characteristics differ. The AMD Radeon R9 M390X is also close at 20662, but this is an older architecture that may not support all modern rendering features.

For builders considering alternatives, the 8400F's 77th percentile ranking among all CPUs means it is a solid mid-range choice, while the B570's 65th percentile GPU ranking indicates it is slightly below average in the broader GPU landscape. A system with a Ryzen 5 7500F and Arc A750 would behave almost identically to this configuration.

The Verdict

This PC can run Lockdown Protocol playably at 1080p and 1440p, but not at 4K. At 1920x1080, all four presets — Low, Medium, High, and Ultra — clear the 60 FPS threshold, with Ultra averaging 63 FPS. This makes 1080p the ideal resolution for this system, allowing gamers to use the highest settings without compromising smoothness.

At 2560x1440, three presets are playable: Low at 100 FPS, Medium at 71 FPS, and High at 62 FPS. Ultra falls short at 46 FPS. The Medium preset offers the best combination of visual quality and performance, with a minimum of 60 FPS ensuring no drops below the playability threshold. High is technically playable but leaves less headroom for demanding scenes.

At 3840x2160, only Low settings achieve playable frame rates, averaging 64 FPS. Medium averages 46 FPS, High averages 40 FPS, and Ultra averages 30 FPS. For 4K gaming, this system requires significant compromises — essentially turning the game down to its lowest visual quality to maintain smooth gameplay. The data clearly indicates that 4K is not this system's intended resolution for Lockdown Protocol.

FAQ

Q: Can this system run Lockdown Protocol at 60 FPS on Ultra settings?

A: Yes, but only at 1920x1080, where Ultra averages 63 FPS. At 2560x1440, Ultra drops to 46 FPS, and at 3840x2160, Ultra averages 30 FPS.

Q: What is the best resolution to use with this PC?

A: 1920x1080 is the best resolution, as all four presets clear 60 FPS. The highest playable preset at 1440p is High at 62 FPS, while 4K is limited to Low settings at 64 FPS.

Q: How does the Intel Arc B570 compare to the Intel Arc A750 in this game?

A: The two GPUs are nearly identical in benchmark performance, with the B570 scoring 20556 and the A750 scoring 20582, a difference of just -0.1%. Frame rates would be virtually indistinguishable.

Q: Is the Ryzen 5 8400F a bottleneck at 1080p?

A: No, the data suggests the CPU is sufficient at 1080p. The 8400F's average benchmark score of 25005 places it in the 77th percentile, and the GPU becomes the limiting factor as resolution increases.

Q: What frame rates can I expect at 1440p Medium settings?

A: Medium settings at 1440p average 71 FPS, with a minimum of 60 FPS and a maximum of 81 FPS. This provides a consistently smooth experience with no drops below the playability threshold.

Q: Why does 4K performance drop so significantly?

A: The Arc B570's compute power, rated at 11.52 TFLOPS, is insufficient for high-fidelity 4K rendering. At 4K, the GPU becomes heavily overloaded, with High settings averaging only 40 FPS and Ultra dropping to 30 FPS.

Best Settings per Resolution

At 3840x2160, the best playable setting is Low, which averages 64 FPS. Medium, High, and Ultra all fall below 60 FPS, so Low is the only viable option for smooth gameplay at this resolution.

At 2560x1440, High settings provide the best visual quality while maintaining playability, averaging 62 FPS. Medium is also a strong choice at 71 FPS with a 60 FPS minimum, but High offers better fidelity for a modest frame rate cost.

At 1920x1080, Ultra settings are fully playable with an average of 63 FPS. This is the most demanding preset that stays at or above 60 FPS, and it is the recommended configuration for 1080p gaming. The system has enough headroom that even the highest quality settings do not compromise smoothness.
