Lockdown Protocol

The pairing of the AMD Ryzen 5 4600G with the NVIDIA GeForce RTX 5090 creates an enormous performance gap between the processor and the graphics card. The RTX 5090 sits in the 94th percentile of all GPUs, while the 4600G is a 6-core, 12-thread Zen 2 part with a base clock of 3.70 GHz and a boost of 4.20 GHz. This is a combination where the GPU is clearly the dominant component, and the measured frame rates in Lockdown Protocol reflect that imbalance at every resolution and settings level.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep but not catastrophic, which tells you the GPU is doing most of the heavy lifting even at lower resolutions. At High settings, the average FPS falls from 175.9 at 1920x1080 to 158.1 at 2560x1440, a reduction of roughly 10%. Moving to 3840x2160 drops the average to 111.6, which is a 37% decrease from the 1080p figure. This scaling pattern is typical of a GPU-bound scenario, but the fact that the 1080p number is not dramatically higher than the 1440p number suggests the CPU is starting to impose a ceiling at the lower resolution.

The Low settings preset shows a similar but compressed curve: 209.1 at 1080p, 187.4 at 1440p, and 162.6 at 4K. The gap between 1080p and 4K is only 22% here, which is smaller than the High preset’s 37% drop. This indicates that at Low settings, the CPU is more likely to be the limiting factor at 1080p, preventing the GPU from stretching its legs. At 4K Low, the GPU still has enough headroom to push 162.6 FPS, which is well above what most displays can show.

Ultra settings produce the most dramatic scaling, with 159.5 FPS at 1080p, 131.2 at 1440p, and 84.3 at 4K. The 4K Ultra result is less than half of the 1080p Low figure, showing how the combination of high resolution and maximum quality settings saturates the GPU. The data suggests that the RTX 5090 is the primary driver of performance at 4K, while the Ryzen 5 4600G becomes more relevant at 1080p, especially on Low presets.

Settings Recommendations

The measured rows show that Medium settings at 1440p offer a strong balance, delivering 163.7 FPS average. This is only 4.6% lower than the Low preset at the same resolution, but it should provide a visibly better image quality in a fast-paced FPS. At 1080p, Medium hits 186.1 FPS, which is close to the 209.1 Low result and still far above the refresh rate of most monitors. High settings at 1440p drop to 158.1 FPS, which remains playable but starts to close the gap with the Medium preset.

For 4K, the choice is starker. High settings yield 111.6 FPS, which is smooth for most players, while Ultra drops to 84.3 FPS. The difference between Medium and High at 4K is only 20.2 FPS (131.8 vs 111.6), so stepping down from High to Medium is a reasonable trade for a more consistent frame rate. Low at 4K reaches 162.6 FPS, but that preset likely sacrifices too much visual fidelity for a game like this. The data indicates that Medium is the safe default for 4K, while High is acceptable if you prefer quality over a small margin of FPS headroom.

CPU Role

The Ryzen 5 4600G is a 6-core, 12-thread processor built on the Zen 2 architecture, with a 65W TDP and 8 MB of shared L3 cache. Its benchmark scores place it in the 75th percentile of all CPUs, with a Cinebench R23 multicore score of 13593 and a single-core score of 1919. The nearest rivals in the CPU benchmark database include the Intel Core i3-14100T, which scores 17636 on average, a 0.8% advantage, and the Intel Core i3-13100F at 17665, a 1% lead. These are small deltas, meaning the 4600G is competitive with modern low-power quad-core parts in synthetic tests.

In Lockdown Protocol, the CPU’s impact is most visible in the 1080p Low result, where the average FPS of 209.1 appears to be capped by the processor rather than the GPU. The 4.20 GHz boost clock helps, but the 3.70 GHz base clock and modest IPC of Zen 2 limit how many frames the CPU can feed to the RTX 5090. The delta between 1080p Low and 4K Low is 46.5 FPS, which is smaller than the same comparison on the High preset (64.3 FPS). This suggests that at Low settings, the CPU is holding the combo back at lower resolutions, preventing the GPU from reaching its true potential. The 12 threads do provide enough parallelism for the game’s engine, but the per-core performance is the bottleneck.

How This Combo Ranks

This specific combination of the AMD Ryzen 5 4600G and NVIDIA GeForce RTX 5090 ranks 208th out of 1637 tested combos in Lockdown Protocol. That places it in the top 13% of all configurations, which is respectable given the CPU’s age, but the ranking is heavily influenced by the GPU’s strength. The RTX 5090 alone is in the 94th percentile of GPUs, so the combo’s overall position is dragged down by the CPU’s lower percentile standing. The data shows that the GPU is doing most of the work to secure this rank, and a stronger processor would likely push this combo much higher.

The ranking also reflects the game’s sensitivity to CPU performance. At 1080p, the combo delivers 209.1 FPS on Low, but the RTX 5090 is capable of far more in a CPU-unlimited scenario. The measured results show that the CPU is the constraining factor at lower resolutions, which is why the combo does not crack the top 100. Still, a rank of 208 out of 1637 means this pairing is faster than the vast majority of systems tested, and the GPU ensures high frame rates at 4K where the CPU’s limitations are less pronounced.

GPU Role

The NVIDIA GeForce RTX 5090 is the clear star of this pairing. It features 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth, which is more than enough for 4K textures in Lockdown Protocol. The GPU has 21760 shading units and a boost clock of 2407 MHz, with a FP32 performance of 104.8 TFLOPS. It sits in the 94th percentile of all GPUs, with an average benchmark score of 84306. Its nearest rivals include the RTX 5090 D, which is 0.1% faster, and the RTX 5050 Mobile, which is 0.2% faster, though those are likely not direct competitors in this context.

In the measured FPS data, the GPU’s dominance is clear at 4K. At High settings, the combo averages 111.6 FPS, and at Low it reaches 162.6 FPS. These are high numbers for 4K, but they are not as high as the GPU’s raw compute would suggest, because the CPU is limiting the frame rate at lower settings. The 32 GB VRAM is not a factor in these tests, as the game’s memory usage is unlikely to exceed that capacity at any resolution. The GPU’s role is to provide the massive fill rate and shader throughput needed to maintain playable frame rates at 4K Ultra, which it does at 84.3 FPS, though that is the weakest result in the entire dataset.

Measured FPS Breakdown

At 1920x1080, the combo achieves 209.1 FPS on Low, 186.1 FPS on Medium, 175.9 FPS on High, and 159.5 FPS on Ultra. The spread from Low to Ultra is 49.6 FPS, which is the largest of any resolution, indicating that the CPU is the limiting factor at the lowest settings. Moving to 2560x1440, the results are 187.4 FPS on Low, 163.7 on Medium, 158.1 on High, and 131.2 on Ultra. The gap between Low and Ultra narrows to 56.2 FPS, showing the GPU taking on more of the workload.

At 3840x2160, the averages are 162.6 FPS on Low, 131.8 on Medium, 111.6 on High, and 84.3 on Ultra. The difference between Low and Ultra here is 78.3 FPS, the largest of all resolutions, which confirms that the GPU is fully engaged at 4K. The 1440p Medium result of 163.7 FPS is the most balanced figure in the dataset, offering a high frame rate with a moderate settings preset. The 1080p Low result of 209.1 FPS is the highest average across all tests, but it is likely CPU-bound, as the GPU has much more to give. The 4K Ultra result of 84.3 FPS is the lowest, but it remains above 60 FPS, making it playable for most users. The data as a whole shows a system that is GPU-heavy, with the CPU capping performance at lower resolutions and the GPU delivering strong 4K results.
