Minecraft: Java Edition

# CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-9400 is a 6-core, 6-thread desktop processor built on the Coffee Lake architecture using Intel's 14 nm process. It runs at a 2.90 GHz base clock and boosts up to 4.10 GHz, with a 65 W TDP. The chip carries 9 MB of shared L3 cache, 256 KB L2 per core, and 64 KB L1 per core, and it supports DDR4 memory over a dual-channel interface with 42.7 GB/s of bandwidth. This is a locked multiplier part (overclocking is not supported) and it is now end-of-life, having launched in October 2018.

In Minecraft: Java Edition, the CPU's 6 physical threads matter because the game's core logic — world generation, entity updates, and redstone simulation — is heavily single-threaded and latency-sensitive. The 4.10 GHz boost clock is the key figure here; higher single-core frequency translates directly into faster chunk updates and smoother block interactions. The Cinebench R23 scores place this chip at 7969 multi-core and 1125 single-core, with an average benchmark score of 2305, which lands it at the 50th percentile among all CPUs — squarely mid-pack.

The nearest rivals show how tight the competition is around this chip. The Intel Core i3-10305 scores 2300, just 0.2% behind, and the Core i3-1125G4 also scores 2299, also 0.2% behind. The Intel Xeon E-2134 trails by 0.4% at 2295, while the Intel Core i7-8809G leads by 0.6% at 2319. This tells you the i5-9400 is not a performance outlier — it is squarely in a cluster of similarly capable CPUs, and the differences are within noise territory. For Minecraft, this means the CPU will not be a bottleneck at lower resolutions, but it also will not provide headroom for massive modded servers or extreme view distances, given its 6 threads and no hyper-threading.

# GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4060 Ti 8 GB is built on the Ada Lovelace architecture using TSMC's 5 nm process, with a chip size of 188 mm² and 22,900 million transistors. It runs at a 2310 MHz base clock and boosts to 2535 MHz, with memory clocked at 2250 MHz (18 Gbps effective). The 8 GB of GDDR6 memory sits on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The card has 4352 shading units, 136 TMUs, 48 ROPs, 34 RT cores, and 136 tensor cores, with pixel rate of 121.7 GPixel/s and texture rate of 344.8 GTexel/s. FP32 throughput is 22.06 TFLOPS, and the card draws 160 W TDP with a suggested 450 W PSU.

For Minecraft: Java Edition, the GPU's job is primarily rendering the scene and handling shaders, but the game is not traditionally GPU-bound at lower settings — that changes at 4K Ultra. The 8 GB VRAM is ample for this game's blocky textures, even with high-resolution texture packs, and the 288.0 GB/s bandwidth ensures texture streaming is not a constraint. The 3DMark Steel Nomad DX12 score of 2913 places this GPU at the 17th percentile among all GPUs, which seems low but is misleading for this game.

The nearest GPU rivals are a mixed bag. The GeForce GT 555M matches at 2913 with 0% delta, and the RTX 4060 Ti 16 GB scores 2907, just 0.2% behind. The GT 650M is 0.7% behind at 2893, and the GTX 860M is 1.5% ahead at 2959. This cluster of scores, spanning mobile and desktop parts from different eras, suggests the 3DMark benchmark is not a pure measure of this card's rasterization power in a game like Minecraft. The launch MSRP is 399 USD.

# Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of GPU-bound behavior at higher resolutions and CPU-bound behavior at lower ones. At 1080p Low, the combo hits 452.4 FPS; at 1440p Low it drops to 338.2 FPS; and at 4K Low it falls to 179.2 FPS. That is a 60% drop from 1080p to 4K at Low settings. But at 1080p Ultra the FPS is 209, and at 4K Ultra it drops to 67.4 — a 68% reduction. The fact that the Low setting still loses 60% from 1080p to 4K indicates the GPU is becoming the limiter even at Low, because the game is pushing more pixels regardless of shader complexity.

Look closer at the Medium and High settings. At 1080p Medium the combo produces 417.3 FPS; at 1440p Medium it drops to 265.8 FPS; at 4K Medium it falls to 142.8 FPS. The drop from 1080p to 1440p is 36%, and from 1440p to 4K is another 46%. At High settings, 1080p gives 338 FPS, 1440p gives 215.1 FPS, and 4K gives 112.8 FPS — drops of 36% and 48% respectively. These percentages are nearly identical across Medium and High, suggesting the scaling is resolution-driven, not setting-driven, which points squarely at the GPU as the bottleneck as resolution climbs.

The Ultra setting tells a different story. From 1080p Ultra at 209 FPS to 1440p Ultra at 131.4 FPS is a 37% drop, but from 1440p to 4K Ultra the drop is 49% down to 67.4 FPS. The absolute numbers at 1080p Ultra (209 FPS) are still far above 60 Hz, but the relative scaling shows the GPU is working progressively harder. This is a GPU that is overkill for 1080p in this game, but at 4K Ultra it is clearly pushed to its limits. The data indicates a balanced system at 1440p, where neither component dominates, but at 4K the GPU is the definitive limiter.

# Settings Recommendations — which preset gives the best experience per the measured rows

For a 1080p display, the data shows that even High settings deliver 338 FPS, which is beyond any high-refresh monitor's capability, and Low pushes to 452.4 FPS. The jump from Medium to High at 1080p costs only 79.3 FPS (417.3 to 338), whereas the jump from High to Ultra costs 129 FPS (338 to 209). The sweet spot at 1080p is High: you get near-identical performance to Medium with better visual quality, and the drop to Ultra is too steep for the marginal visual gain in a block-based game.

At 1440p, High settings produce 215.1 FPS, which still exceeds 144 Hz refresh rates. Medium gives 265.8 FPS, and Low hits 338.2 FPS. The Ultra preset drops to 131.4 FPS, which is below 144 Hz but still smooth for 120 Hz panels. The recommendation here is High: it maintains 215.1 FPS, comfortably above 144 Hz, while offering better shadows and lighting than Medium without the steep cost of Ultra.

At 4K, the picture changes. High settings yield 112.8 FPS, which is above 60 Hz but not by a huge margin. Medium gives 142.8 FPS, a 27% improvement over High, and Low reaches 179.2 FPS. Ultra at 4K drops to 67.4 FPS, which is barely above 60 Hz and not a comfortable experience for a game that often has frame-time spikes during chunk loading. The best choice at 4K is Medium: it delivers 142.8 FPS, which is 27% faster than High and still looks substantially better than Low, with the Ultra preset providing no playable benefit at this resolution.

# How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of the Intel Core i5-9400 and the NVIDIA GeForce RTX 4060 Ti 8 GB ranks 784th out of 1727 tested combos in Minecraft: Java Edition. That places it in the 45th percentile of all tested system pairings — meaning roughly 55% of combos tested by this database outperform it. At first glance, that seems low for a GPU that is only two generations old, but the context matters.

The rank reflects the CPU's age more than the GPU's capability. The i5-9400's 50th percentile standing among CPUs drags the combo down, because Minecraft at lower resolutions is heavily CPU-bound, and the 6-thread processor cannot push the RTX 4060 Ti to its full potential. The GPU's 17th percentile in 3DMark is misleading here; the 3DMark score is a synthetic DX12 test that does not reflect Minecraft's older OpenGL 4.6 rendering path, which is more sensitive to CPU draw call throughput.

Compared to the nearest CPU rivals, the i5-9400 is essentially tied with the i3-10305 and i3-1125G4, all within 0.2% — so swapping to those chips would not change the ranking materially. The GPU's nearest rivals also show a tight cluster, with the RTX 4060 Ti 8 GB being within 1.5% of mobile GTX 860M-class parts in 3DMark, though in real Minecraft terms the 8 GB VRAM and Ada Lovelace architecture should give it a large practical advantage that the synthetic benchmark does not capture.

# FAQ

Q: Is the Intel Core i5-9400 a bottleneck for the RTX 4060 Ti in this game?

A: Yes, at 1080p and 1440p. The CPU's 6 threads and 4.10 GHz boost clock produce 452.4 FPS at 1080p Low and 338.2 FPS at 1440p Low, but the GPU is clearly not the limiting factor at those resolutions — the CPU's 50th percentile standing among all CPUs caps the combo's rank at 784 out of 1727.

Q: What is the best setting for a 144 Hz 1440p monitor?

A: High settings give 215.1 FPS at 1440p, which is above 144 Hz. Ultra drops to 131.4 FPS, which is below 144 Hz. Medium gives 265.8 FPS, so High is the optimal choice for visual quality while staying above the refresh rate.

Q: Why does the GPU rank only 17th percentile in 3DMark but perform well here?

A: The 3DMark Steel Nomad DX12 score of 2913 is a synthetic benchmark that places the card at the 17th percentile, but Minecraft: Java Edition uses OpenGL 4.6, and the game's rendering is less GPU-bound at lower resolutions. At 4K Ultra, the card still manages 67.4 FPS, showing it is not a weak GPU.

Q: How does the i5-9400 compare to its nearest CPU rivals?

A: The i5-9400 scores 2305 average, essentially tied with the i3-10305 (2300, 0.2% behind) and the i3-1125G4 (2299, 0.2% behind). The Xeon E-2134 is 0.4% behind at 2295, and the i7-8809G is 0.6% ahead at 2319.

Q: Is 8 GB of VRAM enough for Minecraft at 4K?

A: Yes. The 8 GB GDDR6 memory on a 128-bit bus with 288.0 GB/s bandwidth is sufficient for the game's textures. At 4K Ultra, the combo still produces 67.4 FPS, and the bottleneck is the GPU's compute, not its memory capacity.

Q: What FPS can I expect at 1080p with this combo?

A: The measured range is from 452.4 FPS at Low to 209 FPS at Ultra. High settings give 338 FPS, and Medium gives 417.3 FPS. All presets far exceed 144 Hz at 1080p.

# Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

1920x1080 (1080p):

• Low: 452.4 FPS
• Medium: 417.3 FPS
• High: 338 FPS
• Ultra: 209 FPS

2560x1440 (1440p):

• Low: 338.2 FPS
• Medium: 265.8 FPS
• High: 215.1 FPS
• Ultra: 131.4 FPS

3840x2160 (4K):

• Low: 179.2 FPS
• Medium: 142.8 FPS
• High: 112.8 FPS
• Ultra: 67.4 FPS

The data shows a consistent hierarchy: Low is always fastest, Ultra always slowest, and the gaps between settings narrow as resolution increases. At 1080p, the difference between Low and Ultra is 243.4 FPS; at 4K, that gap shrinks to 111.8 FPS. This compression of performance spread at higher resolutions confirms the transition from a CPU-bound to a GPU-bound scenario. The minimum FPS values are not recorded in the data, so frame-time consistency cannot be assessed, but the average FPS figures alone indicate that this combo is capable of high refresh rates at 1080p and 1440p, and solid 60+ FPS at 4K on Medium and High settings. The Ultra preset at 4K, at 67.4 FPS, is the only configuration that approaches the 60 FPS floor, and even it clears that threshold.
