Minecraft

Intel Core i5-12400 and NVIDIA GeForce RTX 3080 — Minecraft is a sandbox title from 2011 that scales dramatically with both CPU and GPU, and this pairing produces some of the most extreme frame rates in the database. The measured data shows a system that is almost never the bottleneck, delivering triple-digit averages even at 4K Ultra.

Resolution Scaling

The frame rate curve across resolutions is unusually steep, revealing a workload that shifts from heavily CPU-bound at lower resolutions to GPU-limited only at the very top end. At 1080p High, the combo produces a 383 FPS average; dropping to Low settings catapults that to 610 FPS, which is the highest measured average in this dataset. The fact that 1080p Low exceeds 600 FPS strongly indicates that the Intel Core i5-12400’s single-thread performance is the primary governor at that settings level.

Moving to 1440p, the scaling is nearly linear with resolution. High settings deliver 242 FPS, which is 63% of the 1080p High result — a drop that is consistent with a GPU that has headroom to spare. The Medium preset at 1440p shows a 305 FPS average with a minimum of 259 FPS and a maximum of 351 FPS, suggesting that the RTX 3080 is still not fully saturated. The gap between Low and High at 1440p is 143 FPS (385 vs 242), a smaller relative difference than at 1080p where the gap is 227 FPS (610 vs 383).

The jump to 4K is where the RTX 3080’s 10 GB of GDDR6X memory and 320-bit bus finally start to matter. At 4K High, the average FPS drops to 126, which is 33% of the 1080p High figure. This is a much larger percentage decline than the resolution increase alone would predict (4K has 4x the pixels of 1080p, but the frame rate drops by roughly two-thirds). The 4K Medium row shows a 159 FPS average with a 135 FPS minimum and 183 FPS maximum, while 4K Ultra falls to 79 FPS. The difference between 4K Low (201 FPS) and 4K Ultra (79 FPS) is 122 FPS, demonstrating that the Ultra preset imposes a rendering cost that the GPU cannot fully absorb at this resolution.

The data indicates that 1440p is the sweet spot for this pairing: the 242 FPS High average is high enough to saturate most high-refresh displays, while 4K still remains playable at 126 FPS on High settings. Below 1440p, the system is almost certainly limited by the CPU’s ability to feed draw calls rather than the GPU’s rasterization throughput.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread Alder Lake-S processor with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its benchmark profile shows strong single-thread performance — a 3DMark single-thread score of 910 and a Cinebench R23 single-core score of 2257 — which is critical for Minecraft’s historically single-threaded rendering engine. The PassMark single-thread score of 3456 confirms that this CPU has the per-core speed necessary to drive very high frame rates.

The multi-threaded scores are respectable but not exceptional: Cinebench R23 multi-core is 15989, and Geekbench multi-core is 8564. The 3DMark scores show good scaling from 2 threads (1692) to 8 threads (4745) and max threads (5890), indicating that the 12 threads are being utilized when the workload allows. However, the fact that the 1080p Low average is 610 FPS — more than double the 1080p Ultra average of 240 FPS — suggests that the CPU is not the primary constraint at lower graphics settings; rather, it is the game engine’s frame pacing or draw call submission that caps performance.

The CPU’s 18 MB of shared L3 cache and dual-channel memory support (DDR4 or DDR5) are typical for the platform, and its percentile rank of 72 against all CPUs places it above the median. The nearest rivals show it trading blows with an AMD EPYC 7643 (delta -0.1%), an Intel Core i7-1355U (delta -0.3%), an AMD Ryzen AI 5 330 (delta -0.7%), and an Intel Core i3-14100F (delta +0.9%) in the average benchmark score — a tight grouping that indicates the i5-12400 is solidly mid-pack in raw compute.

In Minecraft specifically, the 4.40 GHz boost clock is likely the most important spec. The measured data shows that at 1080p Low, the frame rate is 610 FPS, which is 2.5x higher than the 4K High result of 126 FPS. This massive gap between resolution presets is typical of a game that becomes CPU-bound when the GPU has little work to do. The i5-12400’s 6 physical cores are sufficient, as Minecraft rarely uses more than a few threads for world generation and entity updates, but the high boost clock ensures that the primary thread can execute quickly.

GPU Role

The NVIDIA GeForce RTX 3080 is an Ampere-architecture GPU with 8704 shading units, 272 TMUs, and 96 ROPs. Its 10 GB of GDDR6X memory runs at 19 Gbps effective across a 320-bit bus, yielding a bandwidth of 760.3 GB/s. The boost clock is 1710 MHz, and the card is rated for a 320 W TDP with a suggested 700 W PSU. These are high-end specs that place it in the 68th percentile of all GPUs.

The GPU’s benchmark scores are strong but not class-leading: PassMark G3D is 25086, and 3DMark Steel Nomad DX12 is 4407. The nearest rivals show a cluster of results within 0.4% — NVIDIA P106-100 (-0.3%), AMD Radeon Pro Vega 16 (-0.3%), AMD Radeon RX 6600M (-0.4%), and AMD Radeon R9 M290X (-0.4%) — which indicates that the RTX 3080’s average benchmark score of 23172 is close to those cards despite their very different architectures.

In Minecraft, the GPU’s role becomes dominant at 4K. The 4K Ultra average of 79 FPS is nearly half the 4K High average of 126 FPS, showing that the Ultra preset’s additional rendering features (likely higher draw distance, fancy graphics, and post-processing) are heavy on the GPU. The 4K Medium result of 159 FPS with a 135 FPS minimum suggests that the RTX 3080 has enough headroom to maintain smooth frame pacing at medium settings, but the 760.3 GB/s bandwidth is insufficient to keep the Ultra preset above 100 FPS at this resolution.

The VRAM capacity of 10 GB is not a limiting factor in the measured data — even at 4K Ultra, the game runs at 79 FPS, which is playable, and there is no evidence of texture thrashing or stutter in the minimum frame rates. The GPU’s 68 RT cores and 272 tensor cores are present but unlikely to be exercised in Minecraft’s default rendering path, which relies on rasterization. The pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s are more relevant metrics for this game’s blocky geometry and simple textures.

How This Combo Ranks

The Intel Core i5-12400 and RTX 3080 combination ranks 1005th out of 3710 tested combos in Minecraft. This puts it in the top 27% of all pairings, which is a strong result for a mid-range CPU paired with a high-end GPU. The rank reflects that there are 1004 combos that achieve higher frame rates, likely using more expensive CPUs with higher boost clocks or multiple GPUs.

The data suggests that the CPU is the limiting factor for this combo’s rank. At 1080p Low, the combo hits 610 FPS, which is extremely high, but the 4K Ultra result of 79 FPS shows that the GPU is not the bottleneck at lower resolutions. If the CPU were upgraded to a model with a higher boost clock or better single-thread performance, the 1080p results would likely improve, potentially pushing the rank higher. However, the 1440p High result of 242 FPS is already sufficient for most high-refresh gaming monitors, and the 4K High result of 126 FPS is well above the 60 FPS threshold for smooth gameplay.

The combo’s percentile rank is 72 for the CPU and 68 for the GPU, so the pairing is roughly balanced in terms of component strength. The measured FPS data confirms that the system is well-matched: neither component is drastically underpowered relative to the other, and the bottleneck shifts gracefully from CPU at 1080p to GPU at 4K.

Settings Recommendations

The measured rows provide clear guidance on which preset to use based on resolution. At 1080p, the Low preset produces 610 FPS, which is overkill for any display — even a 360 Hz monitor would be saturated. The Medium preset yields 483 FPS with a 411 FPS minimum, and High gives 383 FPS. The Ultra preset at 240 FPS is still extremely high, so there is no reason to drop below High for visual quality unless the user prioritizes maximum frame rates for competitive play.

At 1440p, the High preset at 242 FPS is the best balance of visual fidelity and performance. The Medium preset at 305 FPS offers a 63 FPS advantage but sacrifices graphical quality, while Ultra at 151 FPS is still smooth but imposes a 91 FPS penalty over High. The Low preset at 385 FPS is unnecessary unless the user is chasing maximum headroom.

At 4K, the Medium preset at 159 FPS with a 135 FPS minimum is the recommended choice for smooth gameplay, as it maintains a high average while keeping the minimum above 120 FPS. The High preset at 126 FPS is also viable, but the 33 FPS drop from Medium to High (159 to 126) is a significant trade-off for what is likely a modest visual improvement. The Ultra preset at 79 FPS is playable but noticeably less smooth, and the Low preset at 201 FPS sacrifices too much visual quality for a frame rate advantage that is not necessary at this resolution.
