Lockdown Protocol

Lockdown Protocol places the AMD Ryzen 5 4600G and NVIDIA GeForce GTX 1660 Ti combination in the 1417th position out of 1637 tested hardware pairings, a result that places this system firmly in the lower tier of the game’s performance database. The data indicates that this pairing is capable of delivering playable frame rates, but only when settings and resolution are managed carefully. The benchmark results show a system that is more constrained by its graphics subsystem than its processor, yet the CPU’s architectural limits become visible at lower resolutions where the GPU is less burdened.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. This CPU sits in the 75th percentile of all processors according to aggregate benchmark data, with an average benchmark score of 17489. Its nearest rivals include the AMD Ryzen 3 PRO 5355GE, which matches the 4600G’s average score with a 0% delta, and the Intel Core i5-12450H, which is just 0.1% ahead. The processor’s single-thread performance, as measured by a 3dmark_single_thread score of 726, is modest, and this becomes a relevant factor in Lockdown Protocol, a genre where frame pacing often depends on the primary game thread.

In this game’s measured results, the CPU’s influence is most apparent when the GPU is not the bottleneck. At 1920x1080 with Low settings, the system achieves 125.7 FPS, a figure that is 31.6% higher than the 94.1 FPS seen at 2560x1440 Low. This scaling shows that the processor can feed the GPU adequately at lower resolutions, but the gap narrows as resolution increases. The 4600G’s 8 MB of shared L3 cache and dual-channel DDR4 memory support at 51.2 GB/s are adequate for the game’s demands, yet the 3dmark_16_threads score of 4863 and the cinebench_r23_multicore score of 13593 indicate that multi-threaded headroom is not a limiting factor here. The data suggests that the CPU is not the primary constraint in most tested configurations, as the frame rate drops of 26.7% from Low to High at 1080p (125.7 to 74.9 FPS) are more indicative of GPU load than CPU limits.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is the dominant performance factor in this pairing. This Turing-architecture card operates with a base clock of 1500 MHz and a boost clock of 1770 MHz, paired with 6 GB of GDDR6 memory on a 192-bit bus, yielding 288.0 GB/s of bandwidth. The GPU’s average benchmark score of 13925 places it in the 55th percentile of all graphics cards, with its nearest rival being the AMD Radeon RX 570X at just 0.4% ahead. The GTX 1660 Ti’s 1536 shading units and 48 ROPs deliver a pixel rate of 84.96 GPixel/s and a texture rate of 169.9 GTexel/s, but the 6 GB VRAM capacity becomes a clear limiting factor in Lockdown Protocol at higher settings.

The measured FPS data shows a steep performance cliff as settings increase. At 3840x2160, the card drops from 58 FPS on Low to 35.5 FPS on High, a 38.8% reduction, and further to 27.7 FPS on Ultra. This pattern repeats at 2560x1440, where Low produces 94.1 FPS but Ultra falls to 41.5 FPS. The 1920x1080 results are more forgiving, with Low hitting 125.7 FPS and Ultra still managing 56.5 FPS. The VRAM pressure is evident in the 4K results, where the gap between Medium (42.7 FPS) and High (35.5 FPS) is a 16.9% drop, suggesting that the 6 GB frame buffer is being saturated. The GPU’s 3dmark_steel_nomad_dx12 score of 1061 and passmark_directx_12 score of 51 indicate that modern API workloads challenge this card, but the data shows it remains viable for 1080p play.

FAQ

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

A: The measured data shows that 1920x1080 is the only resolution where all settings presets remain above 56 FPS. At 2560x1440, Ultra drops to 41.5 FPS, and at 3840x2160, even Low only reaches 58 FPS.

Q: How does the Ryzen 5 4600G compare to its closest rival?

A: The AMD Ryzen 3 PRO 5355GE has an identical average benchmark score of 17482, a 0% delta from the 4600G’s 17489. The Intel Core i5-12450H is 0.1% ahead with a score of 17475.

Q: Is the GTX 1660 Ti's 6 GB VRAM sufficient for 4K gaming?

A: The benchmark data indicates that at 3840x2160, frame rates range from 58 FPS on Low to 27.7 FPS on Ultra. The steep drop between Medium (42.7 FPS) and High (35.5 FPS) suggests VRAM capacity is strained at this resolution.

Q: What settings preset should be avoided at 1440p?

A: The Ultra preset at 2560x1440 produces only 41.5 FPS, which is below the 56 FPS achieved on High. The data shows a 26.4% performance penalty from High to Ultra at this resolution.

Q: How much faster is this combo at 1080p Low compared to 4K Low?

A: At 1920x1080 Low, the system averages 125.7 FPS, which is 116.7% higher than the 58 FPS at 3840x2160 Low. This demonstrates that resolution scaling is the primary performance lever.

Q: Does the CPU hold back the GPU at lower resolutions?

A: The data shows that at 1080p, the frame rate scales from 56.5 FPS on Ultra to 125.7 FPS on Low, a 122.5% increase. This wide range indicates the GPU is the bottleneck, as the CPU maintains sufficient throughput across all settings.

Measured FPS Breakdown

The measured frame rates for Lockdown Protocol with this hardware combination reveal a consistent pattern across all three resolutions. At 3840x2160, the system produces 58 FPS on Low, 42.7 FPS on Medium, 35.5 FPS on High, and 27.7 FPS on Ultra. The transition from Low to Medium represents a 26.4% drop, while Medium to High is a further 16.9% reduction, and High to Ultra costs another 22.0%. These diminishing returns indicate that the GTX 1660 Ti’s 6 GB frame buffer and 288.0 GB/s bandwidth are the limiting factors at 4K.

Moving to 2560x1440, the results improve substantially. Low settings deliver 94.1 FPS, Medium achieves 67.4 FPS, High produces 56 FPS, and Ultra drops to 41.5 FPS. The gap between Low and Medium is 28.4%, which is the largest single-step reduction at this resolution, suggesting that texture quality and shadow complexity at Medium begin to tax the GPU’s resources. The 1440p results show that High is the highest preset that maintains a comfortable margin above 60 FPS, though it falls short at 56 FPS.

At 1920x1080, the system is most capable. Low settings yield 125.7 FPS, Medium delivers 90.9 FPS, High reaches 74.9 FPS, and Ultra manages 56.5 FPS. The scaling from Low to Ultra is a 55.1% reduction, which is the smallest relative drop across all resolutions. This indicates that at 1080p, the GPU can handle the increased load of higher presets without hitting the same hard limits seen at higher resolutions. The 1080p Medium result of 90.9 FPS is particularly notable, as it offers a 21.4% improvement over High while remaining above the 60 FPS threshold, making it the most balanced preset in the entire dataset.

Settings Recommendations

The measured data provides a clear hierarchy for optimizing the gameplay experience with the Ryzen 5 4600G and GTX 1660 Ti. At 1920x1080, the Medium preset delivers 90.9 FPS, which is 21.4% higher than High’s 74.9 FPS and only 34.8 FPS below Low’s 125.7 FPS. This makes Medium the best experience for players prioritizing smoothness, as it maintains a substantial margin above 60 FPS while preserving visual quality. For players who accept lower visual fidelity, Low at 125.7 FPS is the smoothest option, but the 34.8 FPS gain over Medium is unlikely to be noticeable on most displays.

At 2560x1440, the recommendation shifts to Low, which produces 94.1 FPS. Medium drops to 67.4 FPS, a 28.4% reduction that pushes the experience closer to the edge of playability. High at 56 FPS and Ultra at 41.5 FPS are not recommended, as they fall below the 60 FPS threshold and introduce noticeable stutter in a fast-paced FPS. The 1440p Low preset is the only configuration in this resolution that provides a comfortable buffer, and it is 39.7% faster than the next viable option at Medium.

For 3840x2160, the data is unequivocal: only the Low preset at 58 FPS is playable. Medium at 42.7 FPS, High at 35.5 FPS, and Ultra at 27.7 FPS all fail to maintain a consistent experience. The 58 FPS at 4K Low is marginal, and players should consider lowering the resolution to 1440p for a more stable experience. Across all resolutions, the pattern is consistent: the GTX 1660 Ti’s 6 GB VRAM and 5.437 TFLOPS of FP32 performance are best utilized at 1080p Medium, which offers the optimal balance of frame rate and visual quality according to the measured rows.
