Lockdown Protocol

Lockdown Protocol presents a clear performance scaling pattern for the Intel Core i5-12400 and NVIDIA GeForce RTX 3080 combination, with the GPU becoming the dominant limiting factor as resolution increases. At 1920x1080 with Low settings, the combo produces 251.3 FPS, which drops to 175.6 FPS at Medium, 157.7 FPS at High, and 118.7 FPS at Ultra. The jump from Low to Medium represents a 30.2% reduction in frame rate, while the progression from Medium to High is a more modest 10.2% drop, and High to Ultra costs another 24.7%. This pattern suggests that even at 1080p, the higher presets begin to tax the graphics pipeline substantially, though the CPU still has headroom to push beyond 250 FPS at the lowest settings.

Moving to 2560x1440, the same settings hierarchy shows 182 FPS at Low, 129 FPS at Medium, 115.3 FPS at High, and 87.7 FPS at Ultra. The resolution increase from 1080p to 1440p costs roughly 27.6% performance at Low settings, but the penalty grows to 31.6% at Medium, 26.9% at High, and 26.1% at Ultra. This relatively uniform scaling across presets indicates that pixel throughput is becoming a consistent bottleneck, with the RTX 3080's 760.3 GB/s memory bandwidth and 320-bit bus being exercised more heavily. At 4K, the picture changes dramatically: Low settings deliver 117.1 FPS, Medium drops to 84.7 FPS, High falls to 73.8 FPS, and Ultra bottoms out at 57.2 FPS. The gap between 1440p and 2160p is substantial, 64.9 FPS at Low, 44.3 FPS at Medium, 41.5 FPS at High, and 30.5 FPS at Ultra, demonstrating that the 10 GB GDDR6X frame buffer and 29.77 TFLOPS of FP32 compute are fully saturated at 4K.

Resolution Scaling

The data reveals a classic GPU-bound scenario at higher resolutions, but with an interesting twist at 1080p. At 1920x1080, the spread between Low and Ultra is 132.6 FPS, indicating that the RTX 3080 has ample compute headroom and the i5-12400's 6 cores and 12 threads are keeping pace with frame generation. The 251.3 FPS at Low suggests the CPU is nearing its practical limit for this game's engine, as even a significantly more powerful GPU would likely not push much beyond this figure without a faster processor. However, the 118.7 FPS at Ultra shows that graphics settings have a profound impact, with the GPU's shading units and texture mapping units becoming the deciding factor.

At 2560x1440, the scaling becomes more linear, with each settings tier reducing performance by approximately 20-30 FPS. The 182 FPS at Low remains highly playable, but the 87.7 FPS at Ultra indicates that 1440p Ultra is approaching the edge of what this combo can sustain for competitive play. The 4K results tell a clearer story: the RTX 3080 is the unequivocal bottleneck, with even Low settings producing only 117.1 FPS, a 53.4% reduction from the 1080p Low figure. The 57.2 FPS at 4K Ultra is below the threshold for smooth competitive gaming, and the 73.8 FPS at High suggests users seeking 60+ FPS at 4K should stick to Medium or below. The resolution scaling data indicates that this combo is best suited for 1080p and 1440p gaming, with 4K reserved for less demanding titles or lower presets.

How This Combo Ranks

The Intel Core i5-12400 and NVIDIA GeForce RTX 3080 combination ranks 473rd out of 1637 tested combos in Lockdown Protocol, placing it in the 71st percentile of all possible pairings. This is a strong showing, but not exceptional, given the hardware involved. The CPU alone sits at the 77th percentile vs all CPUs, with an average benchmark score of 19850. Its nearest rivals include the Intel Core i7-9700 at 19831 (0.1% faster), the Intel Core i7-8700 at 19894 (0.2% slower), and the AMD Ryzen Threadripper PRO 5995WX at 19928 (0.4% slower). The i5-12400 essentially trades blows with these older and more expensive processors, which speaks to the efficiency of its Alder Lake architecture.

The GPU positions even higher, at the 80th percentile vs all GPUs, with an average benchmark score of 35787. Its nearest rivals are the AMD Radeon Pro Duo at 35860 (0.2% faster), the AMD Radeon 880M at 35646 (0.4% slower), and the AMD Radeon RX 7900 GRE at 36101 (0.9% faster). The RTX 3080's performance is remarkably close to these competitors, despite being from an earlier generation, which underscores the longevity of its Ampere architecture. The combo's rank of 473 suggests that while both components are individually strong, there are 472 other pairings that achieve higher frame rates in this specific title. This likely reflects the game's sensitivity to both CPU single-thread performance and GPU rasterization power, where newer GPUs with higher clock speeds and more efficient architectures gain an edge.

Settings Recommendations

For 1080p gaming, the data supports using High settings as the sweet spot, delivering 157.7 FPS while maintaining visual quality. The jump from Medium to High costs only 17.9 FPS, but the visual improvements are typically substantial. Ultra at 118.7 FPS is still playable, but the 39 FPS penalty over High is hard to justify unless visual fidelity is paramount. At 1440p, Medium settings at 129 FPS provide the best balance, as High drops to 115.3 FPS and Ultra falls to 87.7 FPS, the latter approaching the threshold where competitive players might notice input lag. The 182 FPS at Low is excessive for most users, but could be valuable for esports scenarios where frame rate trumps visuals.

At 4K, the recommendations shift dramatically. Low settings at 117.1 FPS are the only preset that comfortably exceeds 100 FPS, while Medium at 84.7 FPS and High at 73.8 FPS are acceptable for casual play. Ultra at 57.2 FPS should be avoided, as it dips below the 60 FPS threshold that most gamers consider minimum for smooth motion. The data suggests that users with 4K displays should either accept Low settings for competitive play or drop to 1440p and use High or Ultra presets. The RTX 3080's 10 GB VRAM is sufficient for 4K textures, but the 320-bit bus and 760.3 GB/s bandwidth struggle to feed the GPU's 8704 shading units at this resolution with high settings.

GPU Role

The NVIDIA GeForce RTX 3080 is the primary driver of performance in this combo, particularly at higher resolutions. Its 8704 shading units, 272 texture mapping units, and 96 raster operation units provide substantial rasterization power, evidenced by the 251.3 FPS at 1080p Low. The 10 GB GDDR6X memory operates at 19 Gbps effective across a 320-bit bus, yielding 760.3 GB/s of bandwidth, a figure that becomes critical at 4K, where the 57.2 FPS at Ultra shows the memory subsystem struggling to keep up with the GPU's compute demands. The boost clock of 1710 MHz, combined with the 29.77 TFLOPS of FP32 throughput, allows the card to handle Lockdown Protocol's visual effects at Medium and High settings without issue at 1440p.

The GPU's 80th percentile ranking vs all GPUs, with an average benchmark score of 35787, places it slightly above the AMD Radeon Pro Duo (35860, 0.2% slower) and ahead of the AMD Radeon 880M (35646, 0.4% faster) by a narrow margin. Its 28,300 million transistors on an 8 nm Samsung process give it a transistor density of 45.1M per mm², which is modest by modern standards but sufficient for the 628 mm² die size. The 68 RT cores and 272 tensor cores provide hardware acceleration for ray tracing and DLSS, though the measured FPS data does not include these features. The pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s are the theoretical maxima that explain the 4K performance ceiling, at 3840x2160, fill rate becomes the limiting factor, particularly at Ultra where the 57.2 FPS result indicates the GPU is fully saturated.

CPU Role

The Intel Core i5-12400 serves as a capable partner for the RTX 3080, providing sufficient single-thread performance to avoid severe bottlenecks at lower resolutions. Its 6 cores and 12 threads, based on Alder Lake architecture, operate at a base clock of 2.50 GHz and boost up to 4.40 GHz. The single-thread benchmark scores, 910 in 3dmark, 226 in Cinebench R15, and 3456 in Passmark, indicate strong per-core performance that is essential for Lockdown Protocol's frame pacing. The 18 MB shared L3 cache and 1.25 MB L2 per core help reduce memory latency, which is critical for maintaining high FPS in fast-paced FPS titles. The 65 W TDP and dual-channel DDR4/DDR5 memory support ensure the CPU does not throttle under sustained load, though the 163 mm² die size and 10 nm process node are modest by 2024 standards.

The CPU's 77th percentile ranking vs all CPUs, with an average benchmark score of 19850, shows it rivals the Intel Core i7-9700 (19831, 0.1% slower) and Intel Core i7-8700 (19894, 0.2% faster) despite being a lower-tier part. Its multi-threaded performance, demonstrated by 15935 in Cinebench R23, is sufficient to feed the RTX 3080 at 1080p, as evidenced by the 251.3 FPS at Low settings. However, the data suggests the CPU becomes a secondary bottleneck at 1080p Low, where frame rates exceed 250 FPS, a threshold that challenges even the fastest processors. At 1440p and 4K, the GPU takes over as the primary limiter, and the i5-12400's 12 threads provide enough headroom to avoid stuttering or frame drops. The CPU's 2.50 GHz base clock is conservative, but the 4.40 GHz boost clock ensures responsive performance in single-threaded game logic, which is crucial for maintaining consistent frame times in Lockdown Protocol.
