Lockdown Protocol

The AMD Ryzen 5 8400F and AMD Radeon RX 6600 combination delivers a surprisingly capable Lockdown Protocol experience, though 4K gaming demands significant settings compromises. Benchmark data reveals a clear hierarchy: 1080p is fully playable at maximum quality, 1440p is smooth at High settings, and 4K requires dropping to Low for a consistent frame rate.

Best Settings per Resolution

At 3840x2160, the most demanding preset that maintains at least 60 FPS is Low, which produces an average of 71.6 FPS. The jump from Low to Medium costs 20.8 FPS (from 71.6 to 50.8), pushing the experience below the 60 FPS threshold. High settings at 4K yield 41.4 FPS, while Ultra drops to 33.6 FPS — both are well outside playable territory for this combo.

At 2560x1440, the best playable preset is High, delivering 67.7 FPS. This leaves modest headroom above the 60 FPS floor. Medium settings run at 76.5 FPS, providing a more comfortable buffer if frame-time consistency matters. Low settings hit 109.1 FPS, which suits high-refresh displays. Ultra falls to 51 FPS, just short of playable.

At 1920x1080, the most demanding preset that stays above 60 FPS is Ultra, with an average of 71.1 FPS. This is the only resolution where the combo can run the game at maximum quality without dropping below the playability threshold. High settings deliver 88.1 FPS, Medium reaches 107.2 FPS, and Low tops out at 144 FPS — a perfect match for 144Hz monitors.

CPU and GPU Roles

The scaling pattern across resolutions reveals a GPU-bound workload at higher pixel counts. Moving from 1080p to 1440p at High settings reduces average FPS from 88.1 to 67.7 — a 23.2% performance drop. The further climb to 4K at High cuts performance to 41.4 FPS, a 38.8% reduction from the 1440p figure. This steep degradation as resolution increases indicates the Radeon RX 6600 is the primary bottleneck at 4K.

At lower resolutions, the CPU's role becomes more evident. The Ryzen 5 8400F's 6-core/12-thread configuration with a 4.70 GHz boost clock appears sufficient to feed the GPU at 1080p. The gap between Low and Ultra at 1080p is 72.9 FPS (from 144 to 71.1), suggesting the GPU handles the extra graphical load gracefully while the CPU keeps up. The CPU's 77th percentile ranking among all tested processors and its close benchmark parity with the Ryzen 5 7500F (only 0.2% difference) support this interpretation.

The 1440p results show a balanced system. Medium settings produce 76.5 FPS versus High's 67.7 FPS — a 11.5% difference that indicates neither component is dramatically oversubscribed. At 4K, however, the GPU's 8 GB of GDDR6 memory and 224.0 GB/s bandwidth become limiting factors, as even Medium settings fail to reach 60 FPS. The GPU's 63rd percentile ranking versus the CPU's 77th percentile confirms the graphics card is the weaker link in this pairing.

Measured FPS Breakdown

3840x2160:

• Low: 71.6 FPS average
• Medium: 50.8 FPS average
• High: 41.4 FPS average
• Ultra: 33.6 FPS average

The 4K results show a consistent degradation pattern. Each settings tier costs roughly 8-10 FPS, with the step from Low to Medium being the most punishing (20.8 FPS loss). The spread from best to worst is 38 FPS, demonstrating that Lockdown Protocol's visual quality settings have substantial performance impact at this resolution.

2560x1440:

• Low: 109.1 FPS average
• Medium: 76.5 FPS average
• High: 67.7 FPS average
• Ultra: 51 FPS average

1440p presents a more usable range. Low settings approach triple-digit frame rates, while Medium and High both clear the 60 FPS threshold. The transition from Medium to High costs 8.8 FPS, while High to Ultra costs 16.7 FPS — the latter being the steepest single-step penalty at this resolution.

1920x1080:

• Low: 144 FPS average
• Medium: 107.2 FPS average
• High: 88.1 FPS average
• Ultra: 71.1 FPS average

At 1080p, every preset is playable. Low settings hit the 144 FPS ceiling, likely matching a common refresh rate. The scaling is remarkably linear: each step up from Low costs roughly 20-35 FPS. Ultra's 71.1 FPS average provides enough headroom above 60 FPS that occasional dips shouldn't cause visible stutter.

FAQ

Q: Can this PC run Lockdown Protocol at 4K with playable frame rates?

A: Yes, but only at Low settings, which average 71.6 FPS. Medium (50.8 FPS), High (41.4 FPS), and Ultra (33.6 FPS) all fall below the 60 FPS playability threshold.

Q: What is the best settings preset for 1440p gaming?

A: High settings provide the best visual quality while staying playable, averaging 67.7 FPS. Medium (76.5 FPS) is a safer choice for maintaining higher frame rates, while Ultra (51 FPS) is not recommended.

Q: Is the CPU or GPU more important for this game?

A: The GPU is the limiting factor at higher resolutions. The RX 6600's 63rd percentile ranking versus the CPU's 77th percentile explains why 4K performance degrades sharply. At 1080p, the CPU's 6-core/12-thread design with 4.70 GHz boost clock appears sufficient to avoid bottlenecking.

Q: Does the combo support 144Hz monitors at 1080p?

A: Only at Low settings, which reach 144 FPS exactly. Medium (107.2 FPS), High (88.1 FPS), and Ultra (71.1 FPS) all fall short of 144 FPS but remain comfortably above 60 FPS.

Q: How does this combo compare to other tested configurations?

A: It ranks 2851st out of 3714 tested combos for Lockdown Protocol, placing it in the lower-middle portion of the database. The CPU's nearest rival, the Ryzen 5 7500F, scores nearly identically (0.2% difference), while the GPU trades blows with the RTX 4050 Mobile (0.1% slower).

Q: What frame rate can I expect at 1080p with Ultra settings?

A: The average is 71.1 FPS, which clears the 60 FPS threshold by a comfortable 11.1 FPS margin. This makes Ultra the recommended preset for 1080p displays.

The Verdict

This PC can run Lockdown Protocol, but the experience varies dramatically by resolution. At 1920x1080, the system achieves playable frame rates at every preset, including Ultra at 71.1 FPS. The 1440p results are positive: High settings deliver 67.7 FPS, and Medium provides 76.5 FPS for extra headroom. At 3840x2160, only Low settings (71.6 FPS) clear the 60 FPS bar; Medium, High, and Ultra all fall short.

For competitive play at 1080p, the 144 FPS average at Low settings makes this combo viable for high-refresh displays. The 1440p High preset (67.7 FPS) is the sweet spot for visual fidelity and smoothness. At 4K, the GPU's memory bandwidth and 8 GB VRAM become clear constraints, limiting users to Low settings for a playable experience.

The data indicates this pairing is well-balanced for 1080p and adequate for 1440p, but it is not a 4K-capable configuration for Lockdown Protocol beyond minimum quality. Users prioritizing 4K should consider a stronger GPU, while those targeting 1080p high-refresh gaming will find this combo performs admirably.

How This Combo Ranks

The AMD Ryzen 5 8400F + AMD Radeon RX 6600 combination ranks 2851st out of 3714 tested combos for Lockdown Protocol, placing it in the 23rd percentile of all configurations. This lower-mid-pack positioning reflects the GPU's modest standing; the RX 6600 sits at the 63rd percentile among all GPUs, while the CPU performs better at the 77th percentile.

The CPU's nearest rivals show how competitive the Ryzen 5 8400F is: the Ryzen 5 7500F scores only 0.2% higher, and the Intel Core i7-13620H is 0.4% ahead. On the GPU side, the RX 6600 essentially ties with the Quadro K6000 (0% difference) and trails the RTX 4050 Mobile by a negligible 0.1%.

Given that the GPU ranks lower than the CPU in their respective percentile distributions, the RX 6600 represents the limiting factor in this pairing. For Lockdown Protocol specifically, the combo's overall rank of 2851 suggests that while the CPU is capable, the GPU holds back performance at higher resolutions. The measured FPS data confirms this: playability drops sharply above 1080p, with only Low settings viable at 4K. Users seeking better 1440p or 4K performance would need to upgrade the graphics card, as the CPU has demonstrated sufficient headroom to support faster GPUs.
