Lockdown Protocol

The AMD Ryzen 9 5900X and AMD Radeon RX 6600 combination in Lockdown Protocol exhibits classic resolution-dependent behavior. At 1920x1080, the system delivers 146 FPS on Low settings, which drops to 68 FPS on Ultra—a performance spread that highlights the GPU's workload scaling. Moving to 2560x1440, the average frame rate at Low settings falls to 107 FPS, while Ultra produces 50 FPS. At 4K (3840x2160), the ceiling drops further: Low settings yield 69 FPS, and Ultra falls to 32 FPS. The scaling pattern shows a 53% reduction in average FPS from 1080p Low to 4K Low (146 to 69 FPS), and a 53% reduction from 1080p Ultra to 4K Ultra (68 to 32 FPS).

The transition from 1080p to 1440p at High settings sees a 27% performance drop (90 to 66 FPS), while the jump from 1440p to 4K at High settings results in a 35% reduction (66 to 43 FPS). This non-linear scaling suggests that the Radeon RX 6600's memory subsystem—8 GB of GDDR6 on a 128-bit bus with 224.0 GB/s bandwidth—becomes an increasing constraint as pixel count grows. At 4K, the gap between Low and Medium settings is just 20 FPS (69 vs. 49), while the gap between Medium and Ultra is 17 FPS (49 vs. 32). These compressed margins at high resolution indicate that the GPU is the primary limiting component, with the CPU's contribution diminishing as resolution increases.

CPU Role

The AMD Ryzen 9 5900X brings substantial processing headroom to Lockdown Protocol. This 12-core, 24-thread Zen 3 processor based on the Vermeer architecture operates at a 3.70 GHz base clock and boosts to 4.80 GHz. With 64 MB of L3 cache and dual-channel DDR4 memory support delivering 51.2 GB/s, the CPU's multi-threaded capabilities are well-documented: Cinebench R23 multi-core scores reach 16262 points, while single-core performance registers 1527 points. The 3DMark 16-thread test produces 9075 points, and the max-thread score climbs to 10075.

In the context of Lockdown Protocol, the 5900X's single-thread performance (3DMark single-thread score of 941, Passmark single-thread score of 3469) is likely sufficient to avoid bottlenecking the RX 6600 at lower resolutions. The data shows that at 1080p, the system achieves 146 FPS on Low settings, which suggests the CPU can feed frames at a high rate. However, the percentile ranking of 87th among all CPUs indicates that while this processor is strong, it is not at the absolute top tier. The nearest rivals—Intel Core Ultra 7 366H (avgScore 41263, deltaPct 0.3), Intel Core Ultra 7 356H (avgScore 41215, deltaPct 0.4), AMD Ryzen AI 5 PRO 440 (avgScore 41208, deltaPct 0.4), and Intel Core i7-14650HX (avgScore 41576, deltaPct -0.5)—all fall within 0.5% of the 5900X's average benchmark score of 41376.

The CPU's role in Lockdown Protocol is best understood through the resolution scaling data. At 4K Ultra, the system produces 32 FPS; at 1080p Ultra, it produces 68 FPS. The doubling of resolution more than halves the frame rate, which points to GPU-bound scenarios at high settings. Conversely, the smaller gap between 1080p Low (146 FPS) and 1440p Low (107 FPS)—a 27% drop—suggests that at Low settings, the CPU has more influence on the final frame rate. The 5900X's 12 cores and 24 threads provide ample parallel processing capability, but Lockdown Protocol appears to benefit more from the CPU's strong single-core performance (Geekbench single-core score of 2083) than from its massive multi-threaded throughput (Geekbench multi-core score of 14118).

GPU Role

The AMD Radeon RX 6600, built on the RDNA 2.0 architecture with the Navi 23 chip, is the dominant factor in Lockdown Protocol's performance envelope. This GPU operates with a base clock of 1626 MHz and a boost clock of 2491 MHz, with a game clock of 2044 MHz. The 8 GB of GDDR6 memory on a 128-bit bus provides 224.0 GB/s of bandwidth, which proves adequate for 1080p and 1440p gaming but becomes strained at 4K. The GPU's 1792 shading units, 112 texture mapping units, and 64 raster operation units deliver a pixel rate of 159.4 GPixel/s and a texture rate of 279.0 GTexel/s.

The RX 6600's benchmark profile shows a 3DMark Steel Nomad DX12 score of 1492 and a Passmark G3D score of 15096. The GPU holds a 63rd percentile ranking among all GPUs, with nearest rivals including the NVIDIA Quadro K6000 (avgScore 19030, deltaPct 0), NVIDIA GeForce RTX 4050 Mobile (avgScore 19049, deltaPct -0.1), NVIDIA Tesla K20m (avgScore 19089, deltaPct -0.3), and NVIDIA RTX 2000 Ada Generation (avgScore 18954, deltaPct 0.4). These rivals are all within 0.4% of the RX 6600's average benchmark score of 19036, indicating tight competition at this performance tier.

In Lockdown Protocol, the GPU's VRAM capacity and bandwidth directly influence the measured results. At 1080p, the RX 6600 delivers 146 FPS on Low and 103 FPS on Medium, with the Medium preset showing a minimum of 88 FPS and maximum of 119 FPS. The 4K results tell a different story: Low produces 69 FPS, Medium drops to 49 FPS (min 42, max 56), and Ultra falls to 32 FPS. The RX 6600's FP32 performance of 8.928 TFLOPS and FP16 of 17.86 TFLOPS (2:1) provide the raw compute, but the 224.0 GB/s memory bandwidth appears to be the limiting factor at high resolutions. The GPU's 64 ROPs are tasked with pixel output, and at 4K, the pixel fill rate becomes a bottleneck when combined with higher-quality settings.

Settings Recommendations

For the best experience on this hardware, the data points to 1080p with Medium settings as the sweet spot. At this configuration, the system produces 103 FPS with a minimum of 88 FPS, offering smooth gameplay without the visual compromises of Low settings. The High preset at 1080p drops to 90 FPS, which remains playable but sacrifices 13% of the Medium preset's performance. Ultra at 1080p yields 68 FPS, which is 35% slower than Medium and may introduce visible stutter in fast-paced FPS action.

At 1440p, Medium settings are the highest playable option, delivering 76 FPS with a minimum of 64 FPS. High settings at 1440p reduce the average to 66 FPS, which is still acceptable, but the minimum frame rate data is not recorded. For 4K gaming, only Low settings (69 FPS) provide playable frame rates; Medium (49 FPS) and Ultra (32 FPS) fall below the threshold for competitive play. The measured data shows that the performance gap between Medium and Ultra at any resolution is substantial: 35 FPS at 1080p (103 vs. 68), 26 FPS at 1440p (76 vs. 50), and 17 FPS at 4K (49 vs. 32). These margins suggest that Ultra settings impose a heavy cost without proportional visual gains on this GPU.

A practical approach is to prioritize Medium settings at 1080p or 1440p, depending on display resolution. The Medium preset's recorded minimum and maximum frame rates (88–119 at 1080p, 64–87 at 1440p) indicate stable performance, whereas other presets lack such data. For users with 4K displays, Low settings are the only viable option, as the 69 FPS average at 4K Low aligns with the frame rates seen at 1440p High (66 FPS) and 1080p Ultra (68 FPS).

Measured FPS Breakdown

The complete set of measured frame rates for Lockdown Protocol with the AMD Ryzen 9 5900X and AMD Radeon RX 6600 is as follows:

At 1920x1080:

• Low: 146 FPS average
• Medium: 103 FPS average, 88 FPS minimum, 119 FPS maximum
• High: 90 FPS average
• Ultra: 68 FPS average

At 2560x1440:

• Low: 107 FPS average
• Medium: 76 FPS average, 64 FPS minimum, 87 FPS maximum
• High: 66 FPS average
• Ultra: 50 FPS average

At 3840x2160:

• Low: 69 FPS average
• Medium: 49 FPS average, 42 FPS minimum, 56 FPS maximum
• High: 43 FPS average
• Ultra: 32 FPS average

The data reveals consistent scaling: stepping from Low to Medium costs 43 FPS at 1080p (146 to 103), 31 FPS at 1440p (107 to 76), and 20 FPS at 4K (69 to 49). The transition from Medium to High costs 13 FPS at 1080p (103 to 90), 10 FPS at 1440p (76 to 66), and 6 FPS at 4K (49 to 43). The High to Ultra transition costs 22 FPS at 1080p (90 to 68), 16 FPS at 1440p (66 to 50), and 11 FPS at 4K (43 to 32). These diminishing absolute differences at higher resolutions reinforce the GPU-bound nature of the workload, as the RX 6600's compute and memory resources become saturated. The only preset with complete min/max data is Medium, which at 1080p shows a 31 FPS spread between minimum and maximum, while at 1440p the spread narrows to 23 FPS, and at 4K it compresses to 14 FPS. This tightening of frame variance at higher resolutions indicates more consistent GPU utilization, even as average frame rates decline.
