Lockdown Protocol

Lockdown Protocol presents a demanding workload for the AMD Ryzen 7 3700X and AMD Radeon RX 6650 XT combination, with benchmark results showing a clear sensitivity to both resolution and graphical presets. The measured data indicates that this pairing is best suited for high-refresh-rate 1080p gaming, with performance scaling predictably as resolution increases.

Resolution Scaling

The transition from 1080p to 4K reveals a significant performance drop, highlighting the GPU as the primary bottleneck at higher resolutions. At 1080p with Low settings, the system achieves an average of 165 FPS, which drops to 121 FPS at 1440p and further to 78 FPS at 4K. This represents a 53% reduction in frame rate from 1080p to 4K at Low settings, a scaling pattern typical of a GPU that is increasingly strained by pixel count.

The scaling becomes even more pronounced when examining the High settings preset. At 1080p High, the average is 103 FPS, falling to 75 FPS at 1440p and 49 FPS at 4K. The drop from 1440p to 4K is particularly steep, with a 35% performance loss, suggesting that the RX 6650 XT's 8 GB frame buffer and 128-bit memory interface are being pushed to their limits at 3840x2160. The 4K Ultra preset confirms this, with the system managing only 36 FPS, which is below the threshold for smooth gameplay.

At 1080p, the scaling between presets is less dramatic than at higher resolutions. The difference between Low (165 FPS) and Ultra (77 FPS) at 1080p is 88 FPS, while at 4K the same preset comparison yields only a 42 FPS difference (78 FPS vs 36 FPS). This indicates that at 1080p, the CPU has more headroom to feed the GPU, whereas at 4K, the GPU becomes so saturated that preset changes have a smaller absolute impact on frame rates. The data suggests that for 1440p gaming, users should expect to use Medium or High settings to maintain playable frame rates, as the Ultra preset drops to 56 FPS.

GPU Role

The AMD Radeon RX 6650 XT, based on the RDNA 2.0 architecture with the Navi 23 chip, is the defining component in these results. Its 8 GB of GDDR6 memory on a 128-bit bus provides 280.3 GB/s of bandwidth, which appears sufficient for 1080p and 1440p gaming but becomes a limiting factor at 4K. The GPU's boost clock of 2635 MHz and game clock of 2410 MHz contribute to its 10.79 TFLOPS of FP32 compute, yet the 4K Ultra results show that this raw throughput is not enough to maintain high frame rates in Lockdown Protocol.

The GPU's benchmark percentile of 65 versus all GPUs places it in the mid-range tier, and its nearest rivals include the NVIDIA Tesla K40m and AMD FirePro D300, which are older professional cards. This positioning explains why the RX 6650 XT struggles at 4K, where it achieves only 49 FPS on High settings. The measured FPS at 4K Medium (56 FPS average) with a minimum of 47 FPS and maximum of 64 FPS shows significant frame time variance, indicating that the GPU is working near its capacity.

The GPU's 64 ROPs and 128 TMUs handle texture and pixel processing, and the 32 ray accelerators provide DirectX 12 Ultimate support, but these features do not translate to 4K performance headroom. The data shows that the RX 6650 XT is most comfortable at 1080p, where even the Ultra preset achieves 77 FPS, and at 1440p with Medium settings, which delivers an 86 FPS average. The 4K results, with the best case being 78 FPS on Low, suggest that users should avoid 4K unless they are willing to compromise heavily on visual quality.

Measured FPS Breakdown

The measured data provides a comprehensive view of performance across three resolutions and four quality presets. At 1920x1080, the system delivers its best results: Low settings average 165 FPS, Medium averages 117 FPS with a range of 100-135 FPS, High averages 103 FPS, and Ultra averages 77 FPS. All 1080p presets exceed the 60 FPS threshold, making this resolution the most flexible for the hardware.

Moving to 2560x1440, the performance picture changes. The Low preset averages 121 FPS, which remains highly playable. Medium settings produce an 86 FPS average with a 73-99 FPS range, and High settings drop to 75 FPS. The Ultra preset at 1440p averages just 56 FPS, which is borderline for smooth gameplay in a fast-paced FPS title. The transition from 1080p to 1440p costs roughly 25-30% of performance across presets, which is consistent with the increased pixel workload.

At 3840x2160, the results show a system under significant stress. Low settings average 78 FPS, which is surprising given the resolution, but Medium drops to 56 FPS with a 47-64 FPS range. High settings average 49 FPS, and Ultra falls to 36 FPS. The 4K Medium results, with their 47 FPS minimum, indicate that frame pacing could be inconsistent during intense gameplay moments. The gap between 4K Low (78 FPS) and 4K Medium (56 FPS) is 22 FPS, showing that even modest quality increases have a substantial impact at this resolution.

Settings Recommendations

For 1920x1080 gaming, the Ultra preset at 77 FPS is the best choice for visual quality, as it remains comfortably above the 60 FPS target. Users prioritizing higher refresh rates could select High settings for 103 FPS or Medium for 117 FPS, but the visual fidelity difference between High and Ultra is typically more noticeable than between Medium and High. The 1080p Medium preset's 100 FPS minimum ensures consistent performance even in demanding scenes.

At 2560x1440, the Medium preset provides the best balance, with an 86 FPS average and 73 FPS minimum. This keeps frame rates above the 60 FPS threshold while offering better visual quality than Low settings. The High preset at 75 FPS is also viable, though the lower minimum frame rate could be noticeable in fast-paced action. The Ultra preset at 56 FPS is not recommended for competitive play, as it may dip below playable thresholds during intense combat.

For 3840x2160, the only recommended setting is Low, which averages 78 FPS. The Medium preset's 47 FPS minimum makes it risky for a game where quick reactions are essential, and High and Ultra presets fall below 50 FPS averages. Given the GPU's 65th percentile ranking and the significant performance drop at 4K, users should treat this resolution as a secondary option rather than a primary gaming mode. The data clearly shows that 1080p Medium or High, or 1440p Medium, offers the most consistent experience.

CPU Role

The AMD Ryzen 7 3700X, with its 8 cores and 16 threads, provides a solid foundation for Lockdown Protocol. Its base clock of 3.60 GHz and boost clock of 4.40 GHz, combined with 32 MB of L3 cache, ensure that the CPU is not the limiting factor in most scenarios. The CPU's benchmark performance, including a 22458 Passmark multithread score and a 2656 single-thread score, places it in the 84th percentile versus all CPUs, slightly ahead of the AMD Ryzen AI 7 350 by 0.1% and the Intel Core Ultra 7 165H by 0.5%.

The evidence for CPU headroom is visible in the FPS scaling patterns. At 1080p, where the GPU has less work per frame, the system achieves 165 FPS on Low settings, indicating that the CPU can feed the GPU sufficiently. The 4K results, where the CPU workload per frame is similar but the GPU is far more stressed, show a dramatic FPS drop. This divergence confirms that the RX 6650 XT is the performance limiter, not the Ryzen 7 3700X.

The CPU's 16 threads and Zen 2 architecture, built on TSMC's 7 nm process with 3,800 million transistors, handle the game's background tasks and physics calculations without issue. The 51.2 GB/s dual-channel memory bandwidth is adequate for the DDR4 platform, and the PCIe Gen 4 support with 24 lanes provides sufficient bandwidth for the GPU's PCIe 4.0 x8 interface. The Ryzen 7 3700X's launch MSRP was $329, and its active production status ensures continued availability. Overall, the CPU's performance is more than sufficient for Lockdown Protocol, with the GPU being the component that determines the playable settings at each resolution.
