Lockdown Protocol

# Lockdown Protocol with AMD Ryzen 5 8400F + AMD Radeon RX 6650 XT

The AMD Ryzen 5 8400F paired with the AMD Radeon RX 6650 XT delivers a solid 1080p experience in Lockdown Protocol, with the combo ranking 1053rd out of 1637 tested configurations. This mid-range pairing shows clear strengths at lower resolutions, but the data reveals significant scaling challenges as resolution increases. The measured frame rates across twelve settings/resolution combinations indicate a system that can handle competitive play at 1080p but struggles to maintain high refresh rates at 4K. The CPU's Zen 4 architecture with 6 cores and 12 threads provides adequate processing power, while the GPU's RDNA 2.0 architecture with 8 GB of GDDR6 memory becomes the primary bottleneck at higher resolutions.

CPU Role

The Ryzen 5 8400F is built on the Zen 4 architecture using TSMC's 4 nm process node, featuring 6 cores and 12 threads with a base clock of 4.20 GHz and a boost clock of 4.70 GHz. This processor sits in the 82nd percentile among all CPUs, with an average benchmark score of 25064. Its nearest rival, the AMD Ryzen 7 2700X, scores nearly identically at 25057, showing a delta of 0%. The Ryzen 5 7500F trails slightly at 24993, putting the 8400F 0.3% ahead. The 8400F's single-thread performance is notable: it scores 2943 in Cinebench R23 single-core and 951 in 3DMark single-thread, which translates to strong responsiveness in fast-paced FPS gameplay.

In Lockdown Protocol, the CPU's role becomes evident when examining frame rates at lower settings. At 1080p Low, the system achieves 168.7 FPS, and at 1440p Low it reaches 124.3 FPS. These numbers suggest the 8400F can feed the GPU adequately when graphical load is reduced. The processor's 16 MB of shared L3 cache and 83.2 GB/s memory bandwidth with DDR5 support help maintain consistent frame pacing. The 3DMark multi-threaded scores show scaling from 1874 with 2 threads to 6165 with max threads, indicating the 12 threads handle multi-tasking well. However, the CPU's 65 W TDP and 4 nm process suggest efficiency is a priority, which aligns with the moderate frame rates observed in this title.

Settings Recommendations

The measured data shows a clear progression across quality presets at every resolution. At 1080p, the Low preset delivers 168.7 FPS, which drops to 116.9 FPS on Medium, 105.2 FPS on High, and 78.3 FPS on Ultra. This represents a 53.6% performance penalty from Low to Ultra at 1080p. For competitive play, the Low preset at 1080p offers the highest frame rates, exceeding the 144 Hz refresh rate commonly targeted by FPS players. The Medium preset at 116.9 FPS still provides smooth gameplay for most monitors, while High at 105.2 FPS remains playable but begins to show diminishing returns.

At 1440p, the pattern continues with Low achieving 124.3 FPS, Medium at 85.8 FPS, High at 76.2 FPS, and Ultra dropping to 57.3 FPS. The 4K results show more dramatic scaling: Low hits 77.9 FPS, Medium at 54.4 FPS, High at 51.1 FPS, and Ultra falls to 36.9 FPS. The data suggests the optimal experience balances visual quality and performance at the Medium preset for 1080p and 1440p users. At Medium 1080p, the 116.9 FPS average provides headroom for consistent frame delivery, while 1440p Medium at 85.8 FPS remains smooth for most players. Ultra settings are only viable at 1080p where 78.3 FPS is still playable, but the 36.9 FPS at 4K Ultra indicates this combination cannot handle maximum fidelity at higher resolutions.

Resolution Scaling

The frame rate drop from 1080p to 4K reveals where the bottleneck lies in this system. At Low settings, performance falls from 168.7 FPS at 1080p to 124.3 FPS at 1440p (a 26.3% reduction) and then to 77.9 FPS at 4K (a 53.8% reduction from 1440p). This pattern indicates the GPU becomes increasingly stressed as pixel count rises. The RX 6650 XT's 8 GB of GDDR6 memory on a 128-bit bus with 280.3 GB/s bandwidth is adequate for 1080p but becomes a limiting factor at higher resolutions where texture memory demands increase.

At Ultra settings, the scaling is even more pronounced: 78.3 FPS at 1080p drops to 57.3 FPS at 1440p (a 26.8% decline) and then to 36.9 FPS at 4K (a 35.6% decline from 1440p). The consistent percentage drops across settings suggest the GPU is the primary constraint. The RX 6650 XT's 10.79 TFLOPS of FP32 performance and 168.6 GPixel/s pixel rate are competitive for 1080p but insufficient for 4K Ultra. The CPU's role diminishes at higher resolutions, as evidenced by the smaller relative frame rate differences between Low and Ultra at 4K (77.9 vs. 36.9 FPS) compared to 1080p (168.7 vs. 78.3 FPS). This indicates that at 4K, the GPU is fully saturated while the CPU has headroom remaining.

FAQ

Q: What is the best resolution for this combo in Lockdown Protocol?

A: The data shows 1080p provides the most consistent experience. At Low settings, the system achieves 168.7 FPS, and even at High it maintains 105.2 FPS. The 1440p results are playable but show a significant drop, with High settings delivering 76.2 FPS.

Q: How does the Ryzen 5 8400F compare to its nearest rivals?

A: The 8400F scores 25064 on average, which matches the AMD Ryzen 7 2700X at 25057 (0% delta). It is 0.3% ahead of the Ryzen 5 7500F at 24993 and trails the AMD Ryzen AI 5 PRO 340 by 0.1% (25099). The AMD EPYC 9474F at 25103 is 0.2% ahead.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture using a 7 nm process, featuring the Navi 23 chip with 2048 shading units, 128 texture mapping units, and 64 raster operation units. The GPU operates at a base clock of 2055 MHz with a boost clock of 2635 MHz, and its 8 GB of GDDR6 memory runs at 17.5 Gbps effective on a 128-bit bus, delivering 280.3 GB/s of bandwidth. The card's 10.79 TFLOPS of FP32 performance and 337.3 GTexel/s texture rate place it in the 72nd percentile among all GPUs, with an average benchmark score of 29024.

In Lockdown Protocol, the GPU's role is clearly defined by the measured frame rates. At 1080p, the card delivers 168.7 FPS on Low and 78.3 FPS on Ultra, showing a 53.6% performance range across settings. At 4K, the range narrows to 77.9 FPS on Low and 36.9 FPS on Ultra, a 52.6% spread. This consistent scaling pattern indicates the GPU's 8 GB VRAM and memory bandwidth are sufficient for the game's demands at 1080p but become strained at higher resolutions. The RX 6650 XT's nearest rival, the AMD Radeon RX 6800M, scores nearly identically at 29011, while the RX 470 trails by 0.1% at 28996. The card's 32 ray tracing cores support DirectX 12 Ultimate, though the measured data suggests rasterization performance is the primary factor in this title. The GPU's 176 W TDP and 450 W suggested PSU requirement indicate it is a power-efficient option for mid-range systems.
