Lockdown Protocol

Lockdown Protocol presents a demanding workload that clearly separates the AMD Ryzen 5 5500X3D and AMD Radeon RX 6600 combination from the pack, with the measured data placing this pairing at rank 2213 out of 2828 tested combos. The results show a system that is consistently GPU-bound across the board, where the RX 6600's capabilities define the experience, while the Ryzen 5 5500X3D provides sufficient headroom to avoid becoming a bottleneck at the tested settings.

Resolution Scaling

The measured FPS data reveals a steep performance curve as resolution increases, confirming that the AMD Radeon RX 6600 is the primary limiting component in this pairing. At 1920x1080 with Low settings, the combo achieves 146 FPS, but this drops to 107 FPS at 2560x1440 and further to 69 FPS at 3840x2160. This represents a 26.7% reduction from 1080p to 1440p and a 52.7% reduction from 1080p to 4K, a scaling pattern that strongly suggests the GPU's pixel throughput is the constraining factor rather than the CPU.

The scaling behavior becomes even more pronounced when examining the High preset. At 1080p High, the system delivers 90 FPS, which falls to 66 FPS at 1440p (a 26.7% drop) and then to 43 FPS at 4K (a 52.2% drop from 1080p). The consistency of these percentage drops across different settings presets indicates a purely resolution-driven limitation, with the RX 6600's 224.0 GB/s memory bandwidth and 159.4 GPixel/s pixel rate being taxed progressively harder as the pixel count increases.

Interestingly, the gap between Low and Ultra settings narrows at higher resolutions. At 1080p, the difference between Low (146 FPS) and Ultra (68 FPS) is 78 FPS, but at 4K, the difference between Low (69 FPS) and Ultra (32 FPS) shrinks to 37 FPS. This compression at 4K suggests that the GPU is hitting a hard computational ceiling, where even reducing settings cannot fully compensate for the raw pixel workload. The 4K Ultra result of 32 FPS is particularly telling, as it approaches the lower bounds of playability for an FPS title.

GPU Role

The AMD Radeon RX 6600 is clearly the dominant factor in this combo's performance profile. With 8 GB of GDDR6 memory on a 128-bit bus, the GPU provides 224.0 GB/s of bandwidth, which appears sufficient for the tested settings but limits headroom at higher resolutions. The memory clock runs at 1750 MHz (14 Gbps effective), and the boost clock of 2491 MHz with a game clock of 2044 MHz define the card's operational envelope.

The GPU's architectural specifications explain the observed scaling patterns. With 1792 shading units, 112 texture mapping units, and 64 ROPs, the RX 6600 delivers 8.928 TFLOPS of FP32 performance. The 3DMark Steel Nomad DX12 score of 1492 and Passmark G3D score of 15096 place this GPU in the 63rd percentile of all GPUs, with nearest rivals including the NVIDIA Quadro K6000 (0% delta) and NVIDIA GeForce RTX 4050 Mobile (-0.1% delta). This mid-range positioning aligns with the measured FPS figures, which show the card capable of 1080p gaming at high refresh rates but struggling to maintain 60 FPS at 4K on higher presets.

The VRAM allocation becomes a potential concern at 4K Ultra, where the 32 FPS average suggests the GPU is not only compute-bound but potentially memory-constrained. The 8 GB frame buffer is adequate for 1080p and 1440p in this title, but the 4K Ultra result, combined with the narrow gap between Medium (49 FPS) and High (43 FPS) at 4K, indicates that the card is operating at its limits in terms of both fill rate and memory capacity.

How This Combo Ranks

The combo ranks 2213 out of 2828 tested combinations in Lockdown Protocol, placing it in the lower portion of the distribution. This ranking reflects the RX 6600's mid-range position (63rd percentile of GPUs) combined with the Ryzen 5 5500X3D's solid but not exceptional standing (85th percentile of CPUs). The rank suggests that while this pairing can handle the game at 1080p and 1440p on reduced settings, it trails many other configurations in the database.

The gap between the CPU and GPU percentiles is instructive. The Ryzen 5 5500X3D's 85th percentile ranking indicates strong CPU performance relative to the broader market, but the GPU's 63rd percentile holds the combo back. This is consistent with the resolution scaling analysis, which showed the GPU as the limiting factor. The data suggests that the CPU is underutilized in this title, as evidenced by the fact that FPS scales almost entirely with resolution rather than showing CPU-related bottlenecks at lower resolutions.

The rank of 2213 out of 2828 means that approximately 21.7% of tested combos perform worse than this pairing, while 78.3% perform better. This places the combo in a challenging position for Lockdown Protocol, which appears to be a demanding title that favors GPUs with higher pixel throughput and memory bandwidth than the RX 6600 provides at 4K.

CPU Role

The AMD Ryzen 5 5500X3D provides a robust foundation for this gaming combo, with 6 cores and 12 threads operating at base clock of 3.00 GHz and boost clock of 4.00 GHz. The 96 MB shared L3 cache is a standout feature, likely providing excellent game-level caching for Lockdown Protocol's data-heavy workloads. The CPU's Passmark multi-thread score of 20363 and single-thread score of 2941 indicate balanced performance that can handle both the game's main thread and background tasks without issue.

The CPU's nearest rivals in synthetic benchmarks illustrate its competitive position. The AMD Ryzen 5 5600F scores 36945 (0.2% lower), the AMD Ryzen AI 7 PRO 450 scores 37093 (0.2% higher), and the Intel Core Ultra 5 225 scores 36938 (0.2% lower). This clustering within 0.3% suggests that the 5500X3D is in a tightly contested performance tier where no meaningful differences exist in general CPU workloads.

In the context of Lockdown Protocol, the CPU's role appears secondary to the GPU. The 105 W TDP and 7 nm TSMC process node indicate efficient operation, and the DDR4 memory support with 51.2 GB/s bandwidth provides adequate data throughput for the game's engine. The measured FPS data shows no signs of CPU bottlenecking—if the CPU were limiting, we would expect to see FPS plateaus across different resolutions, but instead we see consistent scaling that tracks GPU load.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce 146 FPS average, Medium achieves 103 FPS with a min/max range of 88 to 119 FPS, High reaches 90 FPS, and Ultra drops to 68 FPS. The Medium preset's range of 88-119 FPS shows good frame pacing, with the 31 FPS spread indicating stable performance under load.

Moving to 2560x1440, the performance scales as expected. Low settings maintain 107 FPS, Medium delivers 76 FPS with a min/max of 64 to 87 FPS, High achieves 66 FPS, and Ultra falls to 50 FPS. The Medium range at 1440p (64-87 FPS) shows a wider spread of 23 FPS compared to 1080p, suggesting the GPU is working harder and frame times are less consistent.

At 3840x2160, the RX 6600's limitations become apparent. Low settings still manage 69 FPS, but Medium drops to 49 FPS (min 42, max 56), High falls to 43 FPS, and Ultra bottoms out at 32 FPS. The Medium preset's range of 42-56 FPS represents a 14 FPS spread, which is narrower in absolute terms but represents a larger percentage variation (33.3% of the average) compared to lower resolutions, indicating increased frame time volatility.

Settings Recommendations

For players prioritizing high frame rates at 1080p, the Low preset at 146 FPS is the clear choice, offering more than double the frame rate of Ultra (68 FPS) while likely still providing acceptable visual quality for competitive play. The Medium preset at 103 FPS represents a strong balance, with the 88-119 FPS range ensuring that dips remain above the 60 FPS threshold for smooth gameplay.

At 1440p, the recommended settings shift downward. Low at 107 FPS is the only preset that comfortably exceeds 100 FPS, while Medium at 76 FPS remains viable for those wanting better visuals. The High preset at 66 FPS is marginal, and Ultra at 50 FPS should be avoided for any fast-paced gameplay. The Medium preset's 64-87 FPS range shows that while it can dip below 70 FPS, it maintains playability throughout.

For 4K gaming, the options are severely limited. Low at 69 FPS is the only playable preset, and even this shows signs of strain. Medium at 49 FPS is technically playable but will feel sluggish in an FPS title, while High (43 FPS) and Ultra (32 FPS) are not recommended. Players targeting 4K with this combo should accept significant visual compromises or consider lowering the resolution to 1440p for a better experience. The data clearly indicates that 1080p Medium or 1440p Low provides the best balance of visual fidelity and performance for this hardware combination.
