Lockdown Protocol

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor built on the Zen 4 architecture (Phoenix codename) using TSMC's 4 nm process. It operates with a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The chip carries 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. Memory support is DDR5 over a dual-channel bus, yielding 83.2 GB/s of bandwidth. The CPU sits on the AMD Socket AM5 platform, with PCIe Gen 4 connectivity (20 lanes from the CPU itself).

In synthetic benchmarks, the 8400F posts a single-thread score of 951 in 3DMark and 2943 in Cinebench R23 single-core. Multi-threaded results are stronger: 20851 in Cinebench R23 multicore, 8757 in Cinebench R20 multicore, and 24530 in PassMark multithread. The 3DMark 16-thread score is 6091, while the max-threads score is 6165, indicating that the processor scales well with additional threads up to its 12-thread capacity. The average benchmark score across all tests is 25064, placing it in the 82nd percentile of all CPUs tested.

For Lockdown Protocol, an FPS title, the 8400F's 6 cores and 12 threads are sufficient to handle game logic, physics, and AI workloads without becoming a bottleneck at most settings. The high boost clock of 4.70 GHz helps maintain frame pacing in scenes with many entities. The L3 cache of 16 MB is modest compared to some rivals, but the fast DDR5 memory bandwidth compensates in memory-sensitive scenarios. The CPU's single-thread performance, as reflected in the 3DMark single-thread score of 951, is critical for games that rely heavily on one primary thread for frame submission. The data shows that at 1080p with Low settings, the combo reaches 122.5 FPS average, suggesting the CPU is not the limiting factor at this resolution and setting combination.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of the AMD Ryzen 5 8400F and NVIDIA GeForce GTX 1660 Ti ranks 1431 out of 1637 tested combos in Lockdown Protocol. That places it in the lower 12.6% of all configurations tested for this game, which is a significant finding given that both components are mid-range or older parts. The rank of 1431 indicates that the majority of tested combos deliver higher average frame rates in this title.

The CPU's nearest rivals by average benchmark score include the AMD Ryzen 7 2700X (deltaPct 0%), AMD Ryzen AI 5 PRO 340 (deltaPct -0.1%), AMD EPYC 9474F (deltaPct -0.2%), and AMD Ryzen 5 7500F (deltaPct 0.3%). These are all within 0.3% of the 8400F's average score of 25064, meaning the processor is competitive with these parts in general compute. However, the GPU's nearest rivals—AMD Radeon RX 570X (deltaPct 0.4%), NVIDIA Tesla K10 (deltaPct -0.7%), NVIDIA RTX A2000 Mobile (deltaPct 0.8%), and NVIDIA GeForce GTX 680 (deltaPct 0.8%)—are all similarly close in average score around 13925.

The combination's rank of 1431 out of 1637 suggests that while the individual components are not weak in isolation, the pairing does not excel in Lockdown Protocol specifically. The data indicates that the GPU's 6 GB VRAM and Turing architecture are likely the constraining factors, as the CPU's percentile of 82 is higher than the GPU's percentile of 55. This rank implies that many other combos, even with similar or slightly better GPUs, achieve higher frame rates. The deltaPct values for GPU rivals are all under 1%, indicating the GTX 1660 Ti is closely matched with several older or mobile parts in raw compute, which may explain the mid-to-low tier ranking.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data shows a clear pattern of resolution scaling. At 1080p with Low settings, the combo achieves 122.5 FPS average. Moving to 1440p Low drops the average to 89.7 FPS, a reduction of 26.8%. At 4K Low, the average falls to 60.4 FPS, which is 50.7% lower than the 1080p Low result. This scaling behavior indicates that the GPU is the primary limiting component at higher resolutions, as the CPU's performance headroom is not exhausted at 1080p.

For High settings, the progression is: 77.3 FPS at 1080p, 57.5 FPS at 1440p (a 25.6% drop), and 35.7 FPS at 4K (a 53.8% drop from 1080p). The percentage drops between resolutions are consistent across settings, suggesting a uniform GPU-bound scaling. At Medium settings, the values are 90.6 FPS at 1080p, 63.8 FPS at 1440p (29.6% drop), and 42.1 FPS at 4K (53.5% drop). Ultra settings show 57.7 FPS at 1080p, 42.2 FPS at 1440p (26.9% drop), and 25.9 FPS at 4K (55.1% drop).

The consistent ~25-30% drop from 1080p to 1440p and ~50-55% drop from 1080p to 4K across all settings is a classic signature of GPU-limited performance. The CPU's 6 cores and 12 threads are not the bottleneck here; rather, the GTX 1660 Ti's 6 GB VRAM and 288.0 GB/s bandwidth are insufficient to maintain frame rates as pixel count increases. The 4K High result of 35.7 FPS is particularly telling—it falls below the 60 FPS threshold that most FPS players consider playable, indicating that this combo is not suitable for 4K gaming in this title beyond Low settings.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo delivers the following average FPS: Low settings produce 122.5 FPS, Medium settings yield 90.6 FPS, High settings achieve 77.3 FPS, and Ultra settings drop to 57.7 FPS. The scaling from Low to Ultra at 1080p is a 52.9% reduction, which shows that the GPU's shading units (1536) and texture mapping units (96) are heavily taxed as settings increase. The 1080p results are all above 57 FPS, with Low and Medium exceeding 90 FPS, making this resolution viable for competitive play at lower settings.

At 2560x1440, the measured FPS are: Low at 89.7 FPS, Medium at 63.8 FPS, High at 57.5 FPS, and Ultra at 42.2 FPS. The drop from 1080p to 1440p ranges from 25.6% (High) to 29.6% (Medium). The 1440p Low result of 89.7 FPS is still respectable, but Medium and High hover around the 60 FPS mark, and Ultra falls below 45 FPS. This indicates that 1440p is only suitable for Low settings if smooth gameplay is the priority.

At 3840x2160, the results are: Low at 60.4 FPS, Medium at 42.1 FPS, High at 35.7 FPS, and Ultra at 25.9 FPS. The 4K Low result is barely at 60 FPS, while all other settings fall below 45 FPS. The Ultra setting at 25.9 FPS is nearly unplayable for a fast-paced FPS. The data clearly shows that this combo is not intended for 4K gaming, with even Low settings producing a marginal frame rate. The GPU's 48 ROPs and 5.437 TFLOPS of FP32 compute are simply not enough to handle 8.3 million pixels at 4K with acceptable performance.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce GTX 1660 Ti is built on the Turing architecture (TU116 chip) using TSMC's 12 nm process. It has 1536 shading units, 96 texture mapping units, and 48 ROPs. The base clock is 1500 MHz with a boost clock of 1770 MHz. Memory consists of 6 GB of GDDR6 on a 192-bit bus, providing 288.0 GB/s of bandwidth. The memory clock is 1500 MHz (12 Gbps effective). The GPU's FP32 performance is 5.437 TFLOPS, with FP16 at 10.87 TFLOPS (2:1). The pixel rate is 84.96 GPixel/s and the texture rate is 169.9 GTexel/s. The TDP is 120 W with a suggested PSU of 300 W.

In benchmark scores, the GTX 1660 Ti achieves a PassMark G3D score of 12871 and a PassMark GPU compute score of 5226. The 3DMark Steel Nomad DX12 score is 1061, while Geekbench OpenCL and Vulkan scores are 60863 and 58014, respectively. The average benchmark score is 13925, placing it in the 55th percentile of all GPUs. Its nearest rivals are all within 0.8% in average score, including the AMD Radeon RX 570X and NVIDIA GeForce GTX 680, indicating the 1660 Ti is a mid-tier performer.

For Lockdown Protocol, the 6 GB VRAM is sufficient at 1080p but may be strained at 4K with High or Ultra textures. The 288.0 GB/s bandwidth is a bottleneck when rendering at higher resolutions, as the FPS data shows a sharp decline from 1080p to 4K. The GPU's 1536 shading units are adequate for 1080p Medium and High settings, but the 48 ROPs limit fill-rate-heavy scenes, explaining the 57.7 FPS at 1080p Ultra. The boost clock of 1770 MHz helps maintain performance in lighter scenes, but the overall compute capability (5.437 TFLOPS) caps the frame rate in this FPS title. The combination's rank of 1431 out of 1637 is largely attributable to the GPU's age and mid-range positioning; the CPU is comparatively stronger, as evidenced by its 82nd percentile ranking versus the GPU's 55th percentile.
