Lockdown Protocol

The AMD Ryzen 5 8400F and NVIDIA GeForce GTX 1660 SUPER combination, tested in Lockdown Protocol, occupies the 3166th position out of 3714 total configurations in the database. That places the pair in the bottom 15% of all combinations ranked, a direct consequence of the GPU's limitations at high resolutions. The CPU is a 6-core, 12-thread Zen 4 part with a 4.20 GHz base clock and a 4.70 GHz boost, while the graphics card carries 6 GB of GDDR6 memory on a 192-bit bus with a 1530 MHz base and 1785 MHz boost. Measured average frame rates extend from 36 FPS at 4K High to 123 FPS at 1080p Low, making this a setup clearly biased toward 1080p gaming.

How This Combo Ranks

The 3166th rank in Lockdown Protocol's tested combinations is a low placement, and it is not reflected in the individual component percentiles. The CPU sits in the 77th percentile among all CPUs, with an average benchmark score of 25005 points. The GPU, however, only reaches the 53rd percentile, with an average score of 12986. This large gap between the two components increases the likelihood that the GPU is the primary determinant of the game's frame rates – a conclusion that the measured FPS data confirms. When compared to its aggregate rivals, the CPU's nearest neighbor is the AMD Ryzen 5 750F with an average score of 24964, placing the 8400F a marginal 0.2% ahead. The Intel Core i7-11850H trails by 0.3%, and the Intel Core i7-13620H by 0.4%; the AMD EPYC 9474F runs 0.4% faster. Similarly, the GTX 1660 SUPER leads the NVIDIA GeForce RTX 3050 Ti Mobile and the AMD Radeon RX 580 by 0.4% each, is 0.9% faster than the Radeon 740M, yet falls 0.7% behind the NVIDIA Tesla M2090. These tight deltas illustrate that the GPU is a mid-range silicon wavering at the edge of faster upper-bound rivals, while the CPU is a stronger performer relative to its own category.

The ranking also tells us that, despite the GPU's modest standing, the component pair is substantially slower in Lockout Protocol than many combinations with lower raw silicon scores. The two CPU benchmarks – a 16-thread 3D mark score of 6091 and single-thread 1874 – show enough threading capacity to exceed the game's demands, but only when the CPU is pushed to its absolute limits. The data is measured, not projected, so the ranking is based on actual rendering of the game across the full resolution set. With 4K and Ultra settings delivering sub-30 frame rates, the ranking reflects a system that can't maintain high-refresh play at higher definition.

CPU Role

The Ryzen 5 8400F is built on the 4 nm TSMC process and uses the Zen 4 architecture in the Phoenix form factor. Its 6 cores and 12 threads are accompanied by a base clock of 4.20 GHz, a boost clock of 4.70 GHz, and 16 MB of shared L3 cache. The CPU's integrated graphics are absent, so the GTX 1660 SUPER handles all rendering duties. In Cinebench R23, the 8400F posts 20851 points multicore and 2943 points single-core, which places it just two percent behind the Ryzen 5 7500F in aggregate multi-threading (0.2% delta). The 3DMark single-thread score of 951 and multi-threads of 6,616 reveal a processor that is well-capable of feeding a mid-range GPU at any resolution.

For Lockdown Protocol, an FPS title, the CPU's multi-threaded performance covers the physics and AI simulation required to keep a game world active. The measured data shows that at 1080p Low, the system achieves 123 FPS, and at 1080p Low settings the combination rarely hits a CPU-induced wall. Evidence of this is the nearly linear performance drop when moving from Low to High at 1080p: the average FPS falls from 87 to 76, a modest 11% penalty. If the CPU were the limiting factor, the delta would be more pronounced. The 8400F's L3 cache of 16 MB is typical for the core count, but not as large as some of its rivals. Nevertheless, the CPU-time share is only about 15 micron seconds per frame in the best-case scenario. In multi-threaded tasks, the 20,851 Cinebench R23 multicore score reflects the 12 threads are efficiently deployed.

The CPU's 3DMark 16-thread score of 6091 and 8-thread score of 5275 show that the core count is enough for the game's threading, but not overprovisioned. The MainStream benchmark reveals a peak single-thread result of 3685 points, which does not indicate any problem. The power model is the 65 W TDP, and the base clock of 4.20 GHz can be pushed to 4.70 GHz under load. In long sessions, this thermal headroom will not be the issue because the cTDP may drop to 40% for mobiles, but desktop 8400F is likely to sustain its 4.7 GHz without boost throttling, given the air cooler can move.

The pair of components shows that the 8400F is rarely the bottleneck. However, at 4K Ultra, the average FPS is 27, which is below the threshold for a playable experience, yet the CPU still delivered the same result as at 1080p Ultra (57 FPS). This means the CPU's workload is scale-invariant with resolution, while the GPU's directly scales with pixel count. Therefore, the Ryzen 5 8400F is not the limiting factor in this config; the GPU and its memory load are.

GPU Role

The NVIDIA GeForce GTX 1660 SUPER is based on the TU116 chip using the Turing architecture, manufactured on TSMC's 12 nm process. It has 1,408 shading units, 88 texture units, and 48 ROPs. The core runs at 1530 MHz base and 1785 MHz boost, and the 6 GB of GDDR6 is clocked at an effective 14 Gbps across a 192-bit memory bus, delivering 336 GB/s of bandwidth. The pixel rate is 85.68 GPixel/s and texture rate 157.1 GTexel/s, with a peak FP32 performance of 5.027 TFLOPS. These numbers place the GPU near the top of the 10‑series product line, but still well behind contemporary 8‑nanometer designs. The GPU's PassMark G3D score is 12699; its OpenCL score in GeekBench is 52490.

Against its nearest rivals, the 1660 SUPER is 0.4% faster than a mobile RTX 3050 Ti and a desktop RX 580, and 0.9% faster than an AMD Radeon 740M, but 0.7% slower than the Tesla M2090. This places it in the middle of the current field. However, the 6 GB VRAM is the stickiest limitation. With DirectX 12 12_1 and 1024 ROPS – the render output is at 48. The memory bandwidth of 336 GB/s is sufficient for 1080p to handle texture fetches, but when the engine needs to allocate textures for 4K high settings, the VRAM runs out and forces streaming.

The measured FPS reflects the GPU info: at 1080p High, the average is 76 FPS; at 1080p Ultra, it drops to 57 FPS, which is nearly 20% below the High setting. At 1440p, High gives 56 FPS and Ultra gives 42; at 4K, High yields only 36 FPS, Ultra 27. This pattern shows the GPU as the dominant factor all the way from 1080p Ultra to any 4K preset. Even at Low settings, the GTX 1660 SUPER achieves 90 FPS at 1440p and 58 FPS at 4K – the latter falls just below the 60- FPS target. The performance is thus limited by pixel fillrate and memory bandwidth rather than shader complexity, as evidenced by the fact that moving from Low to High at 1080p costs only 32% performance, but moving from 1080p to 4K Low costs 53% performance.

The GTX 1660 SUPER also supports Vulkan 1.4 and DX12, though the 6 GB pool is a constraint for official textures. In Lockout Protocol, the engine's resource management may be CPU-dependent, but the observed scalability is not. At 1080p Medium, the average FPS is 87, with a min of 74 and max of 100. These are exactly the kind of numbers a 192-bit, 6 GB card maintains in a modern FPS. Given that the average frame times are consistent, there is no sign of CPU throttling, but the GPU power is the constraining factor.

Resolution Scaling

The measured frames reveal how the bottleneck shifts with resolution. At 1080p Low, the system reaches 123 FPS; at 1440p it falls to 90, and at 4K it drops to 58. This is an efficiency scale of about 1.37x between 1080p and 1440p and 2.12x between 1080p and 4K. For High presets, the numbers are 76, 56, and 36 respectively – a decline of 26% from 1080p to 1440p and 53% from 1080p to 4K. The absolute drop in FPS is nearly linear with pixel count, which is characteristic of a GPU-limited scenario: the CPU is idle waiting for the renderer to finish. At 1080p Ultra, 42 FPS is minimum, and 4K Ultra brings it down to 27 – next to a 40% reduction.

Looking at the difference between Low and High within the same resolution, several things are notable. At 1080p, the low-to-ultra range drops by 66 FPS (123 to 57), a 54% reduction. At 4K, the platform of low to high is much harder: from 58 to 36 – a 38% reduction. This points to a non-constant pixel benefit: the GPU's fill rate and memory bandwidth become the limiting factor at high pixel counts even if the render quality is reduced. The same pattern appears when we examine the medium settings, which are the only ones with documented floor and ceiling: at 1920x1080 at Medium we get 74 FPS min and 100 max; at 2560x1440, 54-73; at 3840x2160, 35-47. The intervals are thus wider than the midpoint
