Lockdown Protocol

Lockdown Protocol's measured frame rates for the Intel Core i7-13700K paired with the AMD Radeon RX 6600 reveal a system that is decisively GPU-bound at higher resolutions, but which transitions into a more balanced configuration at 1080p. The data shows a clear and consistent scaling pattern: dropping from 4K to 1440p yields substantial gains, while the jump to 1080p further increases performance, though with diminishing returns at the lowest settings, suggesting the CPU begins to exert its influence.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, highlighting the RX 6600 as the primary limiting factor. At Ultra settings, the average frame rate falls from 65.4 FPS at 1920x1080 to 35.1 FPS at 3840x2160, a reduction of approximately 46%. This indicates that the GPU's rendering throughput is saturated well before the CPU becomes a bottleneck, as the pixel count quadruples while the frame rate does not even halve.

The scaling pattern becomes more pronounced when examining the Low preset. Here, the system achieves 145.7 FPS at 1080p, but this drops to 105 FPS at 1440p and further to 67.9 FPS at 4K. The percentage decline from 1080p to 1440p is 28%, while the drop from 1440p to 4K is 35%. This suggests that even at Low settings, where the GPU's workload is reduced, the RX 6600's 8 GB frame buffer and 128-bit memory interface become increasingly strained as resolution rises.

At Medium settings, the same trend holds: 104.3 FPS at 1080p, 74.6 FPS at 1440p, and 49.7 FPS at 4K. The High preset shows 90.6 FPS, 63.3 FPS, and 43 FPS respectively. The consistent pattern across all presets confirms that resolution scaling is the dominant factor, and the data indicates that the 4K results are firmly in the territory where the GPU is the sole constraint, with the CPU's 16 cores and 24 threads providing ample headroom.

GPU Role

The AMD Radeon RX 6600's specifications directly explain the observed performance ceiling. With 8 GB of GDDR6 memory on a 128-bit bus delivering 224.0 GB/s of bandwidth, the card is positioned as a 1080p-class solution. The boost clock of 2491 MHz and game clock of 2044 MHz are competitive, but the 1792 shading units and 64 ROPs limit the fill rate and pixel throughput, which is exactly what the benchmark results reflect.

The GPU's 7 nm process node and RDNA 2.0 architecture provide efficiency, but the raw performance numbers tell the story. In Lockdown Protocol, the RX 6600's 8.928 TFLOPS of FP32 compute is insufficient to maintain high frame rates at 4K, where even the Low preset only yields 67.9 FPS. The card's 3DMark Steel Nomad DX12 score of 1492 and Passmark G3D score of 15096 place it in the 69th percentile of all GPUs, which aligns with the observed mid-range performance.

The memory subsystem is particularly telling. At 4K Ultra, the card delivers 35.1 FPS, likely due to the 8 GB capacity being stressed by high-resolution textures. The transition from Medium to High at 4K shows a drop from 49.7 FPS to 43 FPS, a 13% penalty, while the jump from High to Ultra costs another 18%. This indicates that the GPU's memory bandwidth and capacity are the limiting factors at higher resolutions, rather than the core clock speed.

How This Combo Ranks

The combination of the Core i7-13700K and RX 6600 ranks 1361 out of 1637 tested combos in Lockdown Protocol, placing it in the lower 17% of all configurations. This ranking is underwhelming given the CPU's strength, but it is entirely consistent with the GPU's mid-range positioning. The data suggests that the processor is not the limiting factor in this pairing, as the CPU's performance percentile is 93rd overall, while the GPU sits at the 69th percentile.

The CPU's average benchmark score of 47282 places it within 0.1% of the Core i7-13700KF (47334) and 0.3% ahead of the EPYC 4364P (47131), confirming its high-end status. In contrast, the GPU's average score of 25235 is effectively tied with the Radeon 890M (25246) and RX 580 2048SP (25287), with a delta of 0% and -0.2% respectively. This wide gap between CPU and GPU capability is the root cause of the low combo ranking, as the system's gaming performance is bottlenecked by the graphics card.

The 4K Ultra result of 35.1 FPS is particularly damaging to the combo's ranking, as it falls below the 60 FPS threshold that most competitive shooters require. Even at 1440p Ultra, the 53.2 FPS average is marginal, and the data indicates that this combination is best suited for 1080p gaming, where it can achieve playable frame rates across all settings.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution. At 1080p, the High preset offers the best balance, delivering 90.6 FPS, which is comfortably above the 60 FPS playability threshold while maintaining visual quality. The Medium preset at 104.3 FPS is also viable for users prioritizing frame rate over fidelity, but High provides a 15% improvement in visual quality for only a 13% FPS cost.

For 1440p users, the Low preset is the only setting that guarantees a smooth experience, with 105 FPS. The Medium preset at 74.6 FPS is playable, but the High preset at 63.3 FPS is borderline, and Ultra at 53.2 FPS is below the ideal threshold. The data suggests that 1440p Medium is the maximum acceptable setting for this combo, as it maintains a 74.6 FPS average without sacrificing too much detail.

At 4K, the situation is more constrained. The Low preset at 67.9 FPS is the only option that approaches smooth gameplay, while Medium at 49.7 FPS and High at 43 FPS are noticeably less fluid. The Ultra preset at 35.1 FPS is not recommended for any serious play, as the frame rate is too low for a fast-paced FPS. Overall, the data indicates that 1080p High is the sweet spot for this hardware combination, offering the best compromise between visual fidelity and performance.

Measured FPS Breakdown

At 1920x1080, the measured average FPS across settings are: Low 145.7, Medium 104.3, High 90.6, and Ultra 65.4. The spread from Low to Ultra is 80.3 FPS, representing a 55% performance drop when maxing out settings. This is the most favorable resolution for the combo, with even the Ultra preset maintaining a playable frame rate.

At 2560x1440, the averages fall to: Low 105, Medium 74.6, High 63.3, and Ultra 53.2. The gap between Low and Ultra narrows to 51.8 FPS, a 49% reduction. The Low preset remains excellent, but the Ultra settings begin to struggle, falling below 60 FPS.

At 3840x2160, the averages are: Low 67.9, Medium 49.7, High 43, and Ultra 35.1. The difference between Low and Ultra is now 32.8 FPS, a 48% drop. Only the Low preset achieves a frame rate above 60 FPS at this resolution. The data shows a consistent pattern: each resolution increase costs roughly 30-40% performance, and each settings tier costs 15-20% performance, with the GPU's limitations becoming more pronounced at higher resolutions.

CPU Role

The Intel Core i7-13700K provides a strong foundation for this system, with 16 cores, 24 threads, and a boost clock of 5.40 GHz. Its benchmark scores are exceptional: Cinebench R23 multicore at 39000, single-core at 5505, and Geekbench multicore at 17731. The processor's 30 MB of shared L3 cache and support for DDR4 and DDR5 memory ensure that it is not the bottleneck in Lockdown Protocol.

However, the CPU's role in this specific game is largely to stay out of the way. At 1080p Low, the system achieves 145.7 FPS, which is likely approaching the point where the CPU's per-core performance begins to matter. The single-thread score of 5505 in Cinebench R23 and 1136 in 3DMark single-thread suggest that the processor has ample headroom, but the 145.7 FPS ceiling at Low settings indicates that even this powerful CPU cannot fully compensate for the GPU's limitations.

The data shows that at 4K, the CPU's utilization is minimal, as the GPU is clearly the limiting factor. The combination of 16 cores and 24 threads is far more than Lockdown Protocol requires, and the processor's 93rd percentile ranking versus all CPUs confirms that it is a high-end component. In this pairing, the CPU's role is to ensure that frame times remain stable, which the benchmark results confirm, as there are no sudden dips or inconsistencies in the measured FPS.
