Lockdown Protocol

The pairing of an AMD Ryzen 5 4600G with an NVIDIA GeForce RTX 5080 is an unusual asymmetry, and the measured frame rates in Lockdown Protocol reflect that tension clearly. The RTX 5080 is a top-tier Blackwell part with a PassMark G3D score of 36565, placing it in the 89th percentile of all GPUs, while the Ryzen 5 4600G is a Zen 2 desktop chip whose multi-threaded PassMark score of 15992 sits in the 75th percentile. Across the twelve measured configurations, the data shows a system that is consistently capable of high frame rates but whose scaling behavior reveals where the bottleneck shifts as resolution and settings change.

Resolution Scaling

The frame rate deltas between 1080p and 4K are the clearest indicator of where this combination's limits lie. At Low settings, the drop from 205.6 FPS at 1920x1080 to 161.1 FPS at 3840x2160 represents a 21.6% reduction in throughput. This is a relatively modest decline for a 4x increase in pixel count, which suggests that at Low settings the CPU is still heavily involved in limiting performance at 1080p; the RTX 5080 is not being fully exercised at the lower resolution, so moving to 4K does not punish it as severely as it would in a GPU-bound scenario.

At Ultra settings, the scaling curve changes shape. The 1080p result is 156 FPS, while 1440p yields 120.9 FPS and 4K falls to 81.2 FPS. The step from 1440p to 4K is a 32.8% drop, which is a much steeper decline than the Low-settings path. This pattern is classic GPU-bound behavior: as the preset becomes more demanding, the RTX 5080's work per frame increases, and the pixel-count penalty grows accordingly. The data indicates that Ultra at 4K is the only configuration where the GPU is clearly the limiting component, whereas at 1080p Ultra the CPU is still holding the system back.

The Medium preset shows a similar but less extreme version of the Ultra curve: 182.9 FPS at 1080p, 166.1 FPS at 1440p, and 117.1 FPS at 4K. The 1440p-to-4K drop here is 29.5%, confirming that the GPU's role expands with settings quality. High settings sit between the extremes, with 176.6 FPS at 1080p, 157.5 FPS at 1440p, and 106.6 FPS at 4K. Across all presets, the 1080p-to-1440p transition is always smaller than the 1440p-to-4K transition, which is consistent with a system that becomes progressively more GPU-limited at higher pixel counts.

GPU Role

The NVIDIA GeForce RTX 5080 brings 16 GB of GDDR7 memory on a 256-bit bus, delivering 960.0 GB/s of bandwidth. Its boost clock is 2617 MHz, and the FP32 throughput is 56.28 TFLOPS. These specifications position it far above its nearest rivals in the database: the Intel Arc A570M scores 58239 in average benchmarks, which is 1.6% lower than the RTX 5080's 59188 average, while the AMD Radeon Pro W5500X trails by 2.6%. The RTX 5080's 89th percentile ranking among all GPUs is reflected in the measured Lockdown Protocol results, where even the weakest configuration (4K Ultra at 81.2 FPS) remains playable.

The VRAM allocation is generous for this title. The 16 GB capacity is unlikely to be a limiting factor at any of the tested resolutions, as Lockdown Protocol's highest measured load occurs at 4K Ultra, where the average FPS is still above 80. The memory clock of 1875 MHz (30 Gbps effective) and the 256-bit bus width explain why the GPU maintains strong performance as resolution scales; the bandwidth headroom is sufficient to feed the 112 ROPs and 10752 shading units without causing a memory-side stall in the measured data.

The GPU's role becomes most apparent when comparing the Low and Ultra presets at the same resolution. At 1080p, the difference between Low (205.6 FPS) and Ultra (156 FPS) is 24.1%, but at 4K the same comparison shows Low at 161.1 FPS versus Ultra at 81.2 FPS, a 49.6% gap. This widening delta is direct evidence that the RTX 5080's compute resources are being more fully utilized as the preset becomes heavier, and the CPU's relative importance diminishes correspondingly.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread Zen 2 part with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. Its Cinebench R23 multi-core score is 13593, and single-core is 1919. These numbers place it in the 75th percentile of all CPUs, with nearest rivals including the Intel Core i5-12450H (0.1% higher average score) and the Intel Core i3-13100F (1% higher). The CPU's 8 MB of shared L3 cache and dual-channel DDR4 support at 51.2 GB/s are modest by modern standards, and the data suggests this limits the system at lower resolutions.

At 1080p Low, the system achieves 205.6 FPS, but the fact that this is only 24.1% higher than 1080p Ultra (156 FPS) — while the GPU is far more capable than the CPU — indicates that the Ryzen 5 4600G is the primary constraint in this region. The single-thread score of 726 in 3DMark and 1919 in Cinebench R23 are respectable but not exceptional, and Lockdown Protocol's frame generation at high FPS likely depends on per-core performance that this chip cannot fully supply to the RTX 5080. The measured 1080p numbers across all presets cluster within a 49.6 FPS range (156 to 205.6), which is a narrow spread for a GPU of this caliber.

The CPU's influence wanes at 4K, where the GPU's workload dominates. At 4K Low, the system produces 161.1 FPS, which is only 21.6% lower than the 1080p Low result. This relatively small penalty suggests that at 4K Low, the RTX 5080 is still not fully saturated, but the CPU is no longer the sole bottleneck either. The 4K Ultra result of 81.2 FPS is where the CPU's limitations are least relevant; here the GPU is clearly the limiting component, and the CPU has ample headroom to feed it.

Measured FPS Breakdown

At 1920x1080, the results span from 156 FPS at Ultra to 205.6 FPS at Low. Medium produces 182.9 FPS, and High lands at 176.6 FPS. The spread between the lowest and highest settings at this resolution is 49.6 FPS, which is the smallest absolute range across all resolutions, reinforcing the CPU-bound nature of 1080p operation.

At 2560x1440, the values compress slightly: Low yields 184.9 FPS, Medium 166.1 FPS, High 157.5 FPS, and Ultra 120.9 FPS. The gap between Low and Ultra here is 64 FPS, which is larger than at 1080p, indicating that the GPU's contribution is growing as pixel count rises. The 1440p Medium result of 166.1 FPS is notable because it is only 9.6% lower than the 1080p Medium result, showing that the system can absorb a substantial resolution increase at moderate settings without a proportional FPS loss.

At 3840x2160, the measurements are 161.1 FPS at Low, 117.1 FPS at Medium, 106.6 FPS at High, and 81.2 FPS at Ultra. The Low setting at 4K is remarkably close to the 1080p Low result (a 21.6% drop), which suggests that at Low settings the RTX 5080 is still not the primary constraint even at 4K. The Ultra setting, however, shows a 47.9% drop from the 1080p Ultra result, confirming that the heaviest preset fully engages the GPU.

The overall pattern across all 12 measurements is consistent: the Ryzen 5 4600G holds back the RTX 5080 at 1080p and at Low/Medium settings, while the GPU's capabilities become the dominant factor at 4K Ultra and, to a lesser extent, 4K High.

Settings Recommendations

For players targeting the highest frame rates, the data shows that 1920x1080 Low delivers 205.6 FPS, which is the maximum measured performance in this configuration. However, this comes at the cost of visual fidelity. The 1080p Medium preset at 182.9 FPS is only 11% slower than Low and likely provides a more balanced experience for competitive play, as the extra settings overhead is negligible given the CPU-bound nature of this resolution.

At 2560x1440, the Medium preset stands out as the most efficient choice. Its 166.1 FPS average is 10.2% higher than the High preset's 157.5 FPS and 27.4% higher than Ultra's 120.9 FPS. Given that the CPU is still a factor at this resolution, Medium avoids the diminishing returns of High and Ultra while maintaining a comfortable margin above 144 Hz refresh rates.

For 4K gaming, the data supports High settings as the sweet spot. The 106.6 FPS average at High is playable on high-refresh displays, while Ultra drops to 81.2 FPS — a 23.8% penalty for what is typically a marginal visual improvement. The 4K Low preset at 161.1 FPS is an option for players who prioritize smoothness over detail, but the High preset's balance of 106.6 FPS with better visuals is more defensible. The Medium preset at 4K (117.1 FPS) is a viable alternative if the 10.6 FPS difference between Medium and High is meaningful for the target display.

Across all resolutions, the Low preset consistently yields the highest FPS, but the Medium preset offers the best compromise between frame rate and visual quality, particularly at 1080p and 1440p. The Ultra preset is only recommended for 1080p, where 156 FPS remains above typical 144 Hz thresholds, and should be avoided at 4K where the 81.2 FPS result leaves little headroom for frame time spikes.
