Minecraft: Java Edition

Resolution Scaling

The measured frame rates for this Intel Core i5-9400 + AMD Radeon RX 6750 XT combination in Minecraft: Java Edition show a clear pattern of GPU-bound scaling as resolution increases. At 1920x1080 with High settings, the combo delivers 307.7 FPS. Moving to 2560x1440 at the same preset drops the average to 196.2 FPS, a reduction of roughly 36%. Pushing further to 3840x2160 brings the average down to 103.5 FPS, which is about 66% below the 1080p figure. This substantial drop across resolution steps indicates that the rendering workload scales heavily with pixel count, a typical signature for a game that becomes increasingly GPU-limited at higher resolutions.

The Low settings preset tells a similar story but with higher absolute numbers. At 1080p Low, the system reaches 452.8 FPS. At 1440p Low, it drops to 305.8 FPS, a 32% decrease. At 4K Low, the average falls to 160.1 FPS, which is 65% lower than the 1080p result. The consistency of these percentage drops across different presets suggests that the limiting component remains the same throughout — the GPU is doing the heavy lifting as resolution climbs, and the CPU has enough headroom to feed it even at lower settings where frame rates exceed 450 FPS.

Ultra settings amplify the resolution sensitivity further. At 1080p Ultra, the combo manages 193.2 FPS. At 1440p Ultra, it drops to 118.6 FPS, a 39% reduction. At 4K Ultra, the average plummets to 60.7 FPS, which is only 31% of the 1080p Ultra figure. The Ultra preset at 4K appears to be the most demanding configuration measured, and the frame rate there suggests the GPU is nearing its practical limit for this game. The jump from Medium to Ultra at any given resolution is also steep — at 1080p, Medium delivers 386.2 FPS while Ultra delivers 193.2 FPS, a 50% penalty for the highest preset.

The data indicates that at 1080p and 1440p, the system is capable of very high frame rates even on High settings, with 307.7 FPS and 196.2 FPS respectively. At 4K, the frame rates remain playable on Low and Medium presets, but the Ultra preset falls to 60.7 FPS, which is borderline for competitive play. This suggests that for players targeting 4K, the limiting factor is squarely the GPU's rendering throughput, not the CPU's processing capability.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with a 7 nm process from TSMC. It features 2560 shading units, 160 texture mapping units, and 64 raster operation units. The GPU has a base clock of 2150 MHz, a game clock of 2495 MHz, and a boost clock of 2600 MHz. Memory consists of 12 GB of GDDR6 on a 192-bit bus, providing 432.0 GB/s of bandwidth. These specifications place the GPU in the 79th percentile against all GPUs in the benchmark database, with an average benchmark score of 35327.

The GPU's nearest rivals in aggregate benchmarks include the AMD Radeon RX 5600M with an average score of 35264 (a 0.2% difference), the NVIDIA GeForce RTX 5070 Ti Mobile at 35435 (0.3% ahead), the AMD Radeon 880M at 35646 (0.9% ahead), and the NVIDIA GeForce RTX 3080 at 35787 (1.3% ahead). This clustering indicates that the RX 6750 XT sits in a tightly competitive performance band, with all four rivals within a 1.3% margin of its average score.

In Minecraft: Java Edition specifically, the GPU's role becomes evident when examining the frame rate deltas between presets. At 1080p, the difference between Low and Ultra is 259.6 FPS (452.8 vs 193.2), which is a massive range that underscores how much the GPU's rendering workload varies with settings. The Medium preset at 1080p delivers 386.2 FPS, which is 85% of the Low preset's output, while High delivers 307.7 FPS, or 68% of Low. These ratios suggest that the GPU has ample compute headroom at lower presets, and the CPU is not the primary bottleneck even at 452.8 FPS.

The GPU's memory bandwidth of 432.0 GB/s and 12 GB capacity are more than sufficient for Minecraft's texture and chunk data at any of the tested settings. The fact that frame rates scale so dramatically with resolution — from 452.8 FPS at 1080p Low to 160.1 FPS at 4K Low — points to the GPU's pixel throughput as the constraining factor. The RX 6750 XT's pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s are the relevant metrics here, and the measured results align with a GPU that becomes progressively more saturated as pixel count rises.

How This Combo Ranks

The Intel Core i5-9400 + AMD Radeon RX 6750 XT combination ranks 870th out of 1727 tested combos in Minecraft: Java Edition. This places it slightly below the median of the tested pool, which is notable given the GPU's strong aggregate benchmark position at the 79th percentile. The CPU, by contrast, sits at the 50th percentile against all CPUs, with an average benchmark score of 2305. The CPU's nearest rivals include the Intel Core i3-10305 at 2300 (0.2% behind), the Intel Core i3-1125G4 at 2299 (0.2% behind), the Intel Xeon E-2134 at 2295 (0.4% behind), and the Intel Core i7-8809G at 2319 (0.6% ahead).

The mid-pack ranking of 870/1727 suggests that while the GPU is capable of high frame rates in isolation, the overall combo does not outperform a significant portion of the tested field in this specific game. This could be due to the CPU's modest single-threaded performance — its Cinebench R23 single-core score is 1125 — which may limit frame rates in Minecraft's CPU-bound scenarios, particularly at lower resolutions where the GPU has spare capacity. The data shows that at 1080p Low, the combo reaches 452.8 FPS, but many other combos in the database presumably exceed that figure, pushing this setup to the 50th percentile rank.

Comparatively, the GPU's nearest rivals in aggregate benchmarks — the RTX 3080 at 1.3% higher average score — would likely place higher in Minecraft's rankings due to superior raw throughput. However, the RX 6750 XT's 12 GB of memory and 432.0 GB/s bandwidth are competitive, and the measured frame rates at 1440p and 4K are respectable. The combo's ranking reflects a balance where the GPU does its part, but the CPU's six cores and six threads at a base clock of 2.90 GHz and boost of 4.10 GHz may not be enough to push this setup into the upper quartile of tested combinations.

Settings Recommendations

For players using this Intel Core i5-9400 + AMD Radeon RX 6750 XT combo, the measured data provides clear guidance on which preset to choose based on target resolution and frame rate goals. At 1920x1080, all four presets deliver playable frame rates, but the differences are stark. Low settings yield 452.8 FPS, which is far beyond what any display can show, so the extra headroom is wasted. Medium at 386.2 FPS and High at 307.7 FPS are both excellent for high-refresh-rate monitors. Ultra at 193.2 FPS is still very smooth, so at 1080p, the choice comes down to visual preference rather than performance necessity.

At 2560x1440, the situation is similar but with a tighter margin. Low delivers 305.8 FPS, Medium 247.2 FPS, and High 196.2 FPS — all suitable for 144Hz or even 240Hz displays. Ultra drops to 118.6 FPS, which is still above 60 FPS and acceptable for most players, but the jump from High to Ultra costs about 40% of the frame rate. For competitive play at 1440p, High is the sweet spot, offering 196.2 FPS with better visuals than Medium. For a more balanced experience, Medium at 247.2 FPS provides a comfortable cushion.

At 3840x2160, the recommendations change significantly. Low delivers 160.1 FPS, Medium 130.2 FPS, and High 103.5 FPS — all playable for 60Hz displays and even some 120Hz panels. Ultra, however, drops to 60.7 FPS, which is just above the 60 FPS threshold but leaves no headroom for frame-time spikes. For 4K gaming, High settings at 103.5 FPS offer the best balance of visual fidelity and smoothness, as the drop from High to Medium only gains about 26 FPS, while the drop from High to Ultra loses about 43 FPS. The data clearly shows that Ultra at 4K is the least efficient preset for this combo.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are as follows: Low settings produce 452.8 FPS, Medium produces 386.2 FPS, High produces 307.7 FPS, and Ultra produces 193.2 FPS. The progression from Low to Medium represents a 15% decrease, from Medium to High a 20% decrease, and from High to Ultra a 37% decrease. This indicates that the Ultra preset imposes a disproportionately large performance penalty compared to the step from Medium to High.

At 2560x1440, the averages are 305.8 FPS for Low, 247.2 FPS for Medium, 196.2 FPS for High, and 118.6 FPS for Ultra. The relative drops are similar: 19% from Low to Medium, 21% from Medium to High, and 40% from High to Ultra. The Ultra penalty becomes slightly more pronounced at this resolution, suggesting that the GPU's shading and texture resources are being taxed more heavily.

At 3840x2160, the averages are 160.1 FPS for Low, 130.2 FPS for Medium, 103.5 FPS for High, and 60.7 FPS for Ultra. The drop from Low to Medium is 19%, Medium to High is 20%, and High to Ultra is 41%. The Ultra preset at 4K produces a frame rate that is only 38% of the Low preset's output, which underscores the extreme cost of the highest settings at this resolution. Across all resolutions, the Ultra preset consistently exacts the largest relative penalty, and at 4K it brings the system to the edge of playability.
