Lockdown Protocol

The Intel Core i5-12400F paired with the AMD Radeon RX 7900 XTX delivers an outstanding experience in Lockdown Protocol, securing a rank of 239 out of 1637 tested combos, placing it comfortably in the top 15% of all configurations. This is a high-end pairing where the GPU's raw power dominates the performance envelope, ensuring that the system is rarely the bottleneck at any resolution. The data indicates a combination that excels at high refresh rate gaming, with the only notable compromise appearing at the extreme 4K Ultra preset where playability dips below the 70 FPS threshold.

How This Combo Ranks

The combo's rank of 239 out of 1637 tested combinations signals a top-tier placement, outperforming the vast majority of systems in the database. This ranking is driven by the synergy between a strong multi-threaded CPU and an exceptionally fast graphics card. The CPU itself, the Intel Core i5-12400F, holds a percentile of 77 against all CPUs, and its benchmark scores show it trading blows with near-identical rivals; it is 0.1% ahead of the Intel Core i7-8700K and 0.3% ahead of the Intel Core i5-1335U, while being only 0.7% behind the AMD Ryzen 5 7533HS. This indicates the processor is more than capable of feeding the GPU. The overall result is a system that is not just fast, but consistently fast, with no single component dragging down the other in most gaming scenarios.

GPU Role

The AMD Radeon RX 7900 XTX is the undisputed performance leader in this pairing, and its specifications explain why. With a massive 24 GB of GDDR6 memory on a 384-bit bus, it offers a bandwidth of 960.0 GB/s, which is crucial for handling the high-resolution textures and complex scenes in a modern FPS. Its RDNA 3.0 architecture, built on a 5 nm process at TSMC, features 6144 shading units and 96 ray accelerators. The clock speeds are equally impressive, with a base of 1929 MHz and a boost of 2498 MHz. These figures translate directly into the measured frame rates, where even at 4K High settings the card pushes an average of 87.4 FPS. This is a GPU designed to obliterate resolution barriers, and the benchmark results confirm that it does so with authority.

Resolution Scaling

The FPS scaling across resolutions reveals the typical pattern of a GPU-bound system, but with a twist. From 1080p to 1440p, the average FPS across all settings drops by roughly 22-24%, which is a moderate decline. However, the jump from 1440p to 4K is more punishing. For instance, at High settings, the system loses about 49 FPS going from 1080p (186.4) to 1440p (136.7), and then loses another 49 FPS going from 1440p to 4K (87.4). This indicates that while the RX 7900 XTX is incredibly powerful, the transition to 4K still places a significant load on the GPU. Interestingly, the Low preset shows the most extreme scaling, from 272.5 FPS at 1080p to 140.7 FPS at 4K, a drop of nearly half, which confirms that the CPU is powerful enough to allow the GPU to be the sole limiting factor even at lower settings.

Settings Recommendations

The measured data provides a clear hierarchy for the best experience. At 1080p and 1440p, the Ultra preset delivers exceptional frame rates of 140.1 and 105.9 FPS respectively, making it the ideal choice for those with high-refresh-rate monitors. However, at 4K, the Ultra preset falls to 64.8 FPS, which is below the 70 FPS threshold many consider smooth for a fast-paced shooter. Therefore, for 4K gaming, the High preset is the recommended sweet spot, as it provides a solid 87.4 FPS while maintaining a higher level of visual fidelity than the Medium preset's 102.3 FPS. The Low preset, while offering the highest frame rates, sacrifices too much visual quality for a marginal gain over Medium at 4K. Ultimately, the best experience is either Ultra at 1440p or High at 4K, depending on the user's display.

Measured FPS Breakdown

The benchmark data paints a comprehensive picture of performance across all settings and resolutions. At 1920x1080, the system is exceptionally fast, with the Low preset hitting an average of 272.5 FPS, Medium at 216.1 FPS, and High at 186.4 FPS. Even the demanding Ultra preset manages a very playable 140.1 FPS at this resolution. Moving to 2560x1440, the frame rates remain high, with Low at 222.1 FPS, Medium at 157 FPS, High at 136.7 FPS, and Ultra at 105.9 FPS. The story changes somewhat at 3840x2160, where the GPU's limits are more apparent. The Low preset still delivers a strong 140.7 FPS, but the Medium preset drops to 102.3 FPS, High to 87.4 FPS, and Ultra to 64.8 FPS. These numbers show a consistent and predictable scaling pattern, with the 1440p High/Ultra settings being the performance sweet spot for this hardware combination.

CPU Role

The Intel Core i5-12400F plays a supporting but critical role in this combo. With 6 cores and 12 threads based on the Alder Lake architecture, it provides a solid foundation for gaming. Its boost clock of 4.40 GHz and a base clock of 2.50 GHz allow it to keep up with the GPU's demands, as evidenced by the high frame rates at 1080p. The CPU's benchmark scores, such as a Cinebench R23 multicore score of 16518 and a single-core score of 2332, indicate that it is not a bottleneck in this system. Its average benchmark score of 19221 is nearly identical to its closest rivals, showing it is a well-balanced mid-range processor. While it doesn't possess the raw multi-core muscle of higher-end chips, its single-thread performance is adequate to push the RX 7900 XTX to its limits in Lockdown Protocol, proving that a 6-core processor can still be a perfect match for a top-tier GPU.
