Lockdown Protocol

The Intel Core i5-12400 paired with the AMD Radeon RX 6750 XT delivers a fundamentally smooth experience in Lockdown Protocol, but with a clear caveat: 4K Ultra is out of reach. Measured data shows the combo ranks 1709th out of 3714 tested configurations, placing it in the upper half of the field. While the CPU and GPU both sit near the 71st-72nd percentile against all other parts, their combined performance in this FPS is defined by resolution scaling. At 1080p and 1440p, the system is overwhelmingly capable; at 4K, it becomes a choice between fluidity and visual fidelity.

Measured FPS Breakdown

The measured FPS data provides a complete picture across three resolutions and four presets. At 1920x1080, the system is never challenged. Low settings produce an average of 200 FPS, Medium averages 142 FPS with a minimum of 121 and a maximum of 164, High averages 124 FPS, and even Ultra holds a solid 93 FPS average. Every preset at 1080p clears the 60 FPS playability threshold by a wide margin, with the gap between Low and Ultra representing a 107 FPS drop.

Moving to 2560x1440, performance remains strong but the scaling begins to show. Low averages 147 FPS, Medium hits 104 FPS with a range of 89 to 120, High delivers 91 FPS, and Ultra drops to 68 FPS. The delta between Low and Ultra here is 79 FPS, narrower than at 1080p, indicating that the GPU is starting to feel the increased pixel load. Still, every 1440p preset clears 60 FPS, with Ultra just 8 FPS above the threshold.

3840x2160 is where the RX 6750 XT hits its limits. Low averages 95 FPS, which remains playable, but Medium drops to 67 FPS with a minimum of 57 and a maximum of 77. High falls to 59 FPS, just below the playable threshold, and Ultra averages 44 FPS. The 51 FPS difference between Low and Ultra at 4K is the largest absolute spread across all resolutions. Notably, only Medium at 4K provides min/max data, showing a 57 FPS minimum that dips below the 60 FPS target even when the average clears it.

CPU and GPU Roles

The data indicates that this pairing is GPU-bound at higher resolutions, while the CPU has ample headroom at 1080p. The i5-12400’s synthetic scores support this: it achieves 15,989 in Cinebench R23 multi-core and 2,257 in single-core, with a 72nd percentile ranking against all CPUs. In Lockdown Protocol, the 1080p Low result of 200 FPS suggests the CPU can feed the GPU well beyond typical refresh rates, as the GPU is not the bottleneck at such low graphical loads.

At 1440p and 4K, the GPU takes on the primary role. The RX 6750 XT’s 13.31 TFLOPS FP32 throughput and 432.0 GB/s memory bandwidth are the limiting factors. The scaling from 1080p Low (200 FPS) to 1440p Low (147 FPS) is a 26.5% drop, while the drop from 1440p to 4K Low (95 FPS) is 35.4%. These diminishing returns are classic signs of GPU-bound rendering, where each pixel costs more compute. The CPU’s role diminishes further at Ultra presets, where the GPU’s 12 GB of GDDR6 memory and 2560 shading units become the deciding factor.

The preset scaling reinforces this. At 1080p, going from Low to Ultra reduces FPS by 53.5%, but at 4K, the same preset change reduces FPS by 53.7%. The near-identical percentage drops across resolutions suggest the CPU is not introducing a bottleneck at any tested setting; the GPU is consistently the primary constraint. The i5-12400’s 12 threads and 18 MB of shared L3 cache appear sufficient for the game’s CPU demands, as no resolution shows a sudden FPS collapse that would indicate thread starvation.

FAQ

*Q: Can this PC run Lockdown Protocol at 4K with playable frame rates?*

A: Yes, but only at Low or Medium settings. At 4K Low, the average is 95 FPS, while 4K Medium averages 67 FPS with a 57 FPS minimum. High (59 FPS) and Ultra (44 FPS) fall below the 60 FPS playable threshold.

Q: What is the best preset for 1440p gaming?

A: Ultra is the best setting at 2560x1440, averaging 68 FPS. This clears the 60 FPS threshold, and all other presets (Low at 147, Medium at 104, High at 91) are also playable.

Q: How does the RX 6750 XT compare to its nearest rivals in synthetic benchmarks?

A: The GPU’s average benchmark score is 26,011. The AMD Radeon R9 M395X scores 25,891 (0.5% slower), the AMD FirePro W7100 scores 25,856 (0.6% slower), and the AMD FirePro D700 scores 25,842 (0.7% slower). The NVIDIA GeForce RTX 3080 Ti Mobile is 1.1% slower with a score of 25,740.

Q: Is the CPU or GPU more important for 1080p performance?

A: The data shows the GPU is the limiting factor even at 1080p. Low settings produce 200 FPS, but Ultra drops to 93 FPS, a 53.5% reduction. The CPU’s 72nd percentile ranking and 15,989 Cinebench R23 multi-core score suggest it can handle the game’s processing demands, but the GPU’s workload scaling dictates the final frame rate.

Q: What is the lowest FPS recorded for any preset in the measured data?

A: The lowest average is 44 FPS at 4K Ultra. The only min/max data provided is for Medium presets: 57 FPS minimum at 4K, 89 FPS at 1440p, and 121 FPS at 1080p.

Q: Does the system maintain 60 FPS in the most demanding settings?

A: At 1080p and 1440p, every preset including Ultra averages above 60 FPS. At 4K, only Low and Medium clear the threshold; High averages 59 FPS and Ultra averages 44 FPS.

The Verdict

This PC can run Lockdown Protocol successfully, but the definition of "success" depends entirely on the target resolution. The verdict data is clear: at 1920x1080, all four presets are playable, with Ultra averaging 93 FPS. At 2560x1440, all four presets are also playable, with Ultra at 68 FPS. At 3840x2160, only Low (95 FPS) and Medium (67 FPS) are playable; High falls just short at 59 FPS, and Ultra is not viable at 44 FPS.

For gamers with a 1080p or 1440p display, this combination offers complete freedom to max out settings. The 1440p Ultra result of 68 FPS is particularly notable, as it provides high-fidelity visuals while staying above the 60 FPS target. At 4K, users must make a compromise: either accept Medium settings with a 67 FPS average (and a 57 FPS minimum that may cause occasional stutter) or drop to Low for a safer 95 FPS average. The 4K High preset’s 59 FPS average is a statistical miss, so the playable ceiling is effectively Medium.

The system’s overall ranking of 1709th out of 3714 combos indicates it sits in the upper half of all tested configurations, which aligns with the CPU’s 72nd and GPU’s 71st percentile standings. This is a well-balanced pairing for 1080p and 1440p gaming, with 4K requiring preset compromises.

Similar Performance Alternatives

Looking at the CPU’s nearest rivals by average benchmark score, the i5-12400 (18,683 average) is nearly identical in performance to the AMD EPYC 7643 (18,697, 0.1% faster) and the Intel Core i7-1355U (18,730, 0.3% faster). The AMD Ryzen AI 5 330 (18,811) is 0.7% faster, while the Intel Core i3-14100F (18,519) is 0.9% slower. Any of these CPUs would deliver effectively the same frame rates in Lockdown Protocol, though the EPYC 7643 and i7-1355U are from different market segments (server and mobile, respectively).

On the GPU side, the RX 6750 XT (26,011 average) is closely matched by the AMD Radeon R9 M395X (25,891, 0.5% slower), AMD FirePro W7100 (25,856, 0.6% slower), and AMD FirePro D700 (25,842, 0.7% slower). The NVIDIA GeForce RTX 3080 Ti Mobile (25,740) is 1.1% slower. These rivals would produce nearly identical FPS numbers, though the FirePro and R9 series are older workstation/mobile parts without modern driver optimizations for gaming. The RTX 3080 Ti Mobile is the closest gaming-oriented alternative, but its 1.1% deficit means it would perform within a few FPS of the RX 6750 XT.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, averaging 93 FPS. This is the maximum visual quality available without compromise.

At 2560x1440, the best setting is also Ultra, averaging 68 FPS. This clears the 60 FPS threshold with 8 FPS of headroom, making it the optimal choice for high-refresh 1440p monitors.

At 3840x2160, the most demanding playable preset is Medium, averaging 67 FPS. However, the 57 FPS minimum recorded for this setting is below the 60 FPS target, so users sensitive to frame pacing may prefer Low settings, which average 95 FPS. High (59 FPS) and Ultra (44 FPS) are not recommended for 4K play.
