Minecraft: Java Edition

Minecraft: Java Edition with an AMD Ryzen 9 5900X and NVIDIA GeForce GTX 1660 SUPER produces a wide spread of frame rates depending on how you balance resolution and quality. The data shows a system that is exceptionally strong at 1080p, capable at 1440p, and still playable at 4K with the right settings, though the GPU becomes the primary constraint as pixel count rises.

Resolution Scaling

The measured FPS numbers reveal a clear pattern: the GTX 1660 SUPER is the limiting component at higher resolutions, while the Ryzen 9 5900X keeps frame rates high at 1080p. At High settings, the average frame rate drops from 187.5 FPS at 1920x1080 to 119.3 FPS at 2560x1440, a 36% reduction. Moving to 3840x2160 at High settings yields just 61.7 FPS, a further 48% drop from 1440p. This steep scaling curve indicates that the GPU is running out of pixel throughput, not that the CPU is holding things back.

The performance gap between Low and Ultra settings widens as resolution increases, which further confirms the GPU bottleneck. At 1080p, the spread from Low (298.8 FPS) to Ultra (118 FPS) is 180.8 FPS. At 1440p, the spread narrows to 112.4 FPS (188 FPS on Low versus 75.6 FPS on Ultra). At 4K, the spread compresses to 59.5 FPS (100.5 FPS on Low versus 41 FPS on Ultra). This compression happens because at 4K the GPU is already saturated even at Low settings, leaving less headroom for quality increases to cost more performance.

For players targeting 60 FPS, the data shows that 4K is achievable only at High settings (61.7 FPS) or Medium settings (76.2 FPS). Dropping to Low at 4K pushes the average to 100.5 FPS, which suggests the game is highly scalable when the GPU is the limiting factor. At 1440p, even Ultra settings maintain a comfortable 75.6 FPS average, while High (119.3 FPS) and Medium (152.7 FPS) offer substantial headroom for monitors with higher refresh rates. At 1080p, the only setting that dips below 118 FPS is Ultra, and even that remains well above typical 60 Hz refresh rates.

FAQ

Q: Can this system run Minecraft at 4K with playable frame rates?

A: Yes. The measured data shows 61.7 FPS average at 3840x2160 with High settings and 76.2 FPS at Medium. Even at Ultra, the average is 41 FPS, which is borderline but workable for less demanding play.

Q: What is the best resolution for high-refresh-rate monitors?

A: At 1920x1080, Low settings produce 298.8 FPS and Medium produces 237.2 FPS, both suitable for 240 Hz displays. At 2560x1440, Low settings hit 188 FPS, which covers most 144 Hz monitors, while High settings at 119.3 FPS suit 120 Hz panels.

Q: How much performance is lost going from Low to Ultra at 1080p?

A: The average frame rate drops from 298.8 FPS on Low to 118 FPS on Ultra, a reduction of 180.8 FPS. This represents a 60% loss in performance for the highest quality preset.

Q: Is the GTX 1660 SUPER the bottleneck in this system?

A: Yes, particularly at higher resolutions. The frame rate drops of 36% from 1080p to 1440p and 48% from 1440p to 4K at High settings point to GPU limits. The Ryzen 9 5900X has ample headroom, as shown by the high 1080p frame rates.

Q: What is the performance difference between High and Ultra settings at 1440p?

A: High settings average 119.3 FPS, while Ultra averages 75.6 FPS. That is a 43.7 FPS difference, making Ultra a significant sacrifice for marginal visual gains at this resolution.

Q: Does the system perform better at 1440p High than at 1080p Ultra?

A: Yes. At 2560x1440 with High settings, the average is 119.3 FPS, which is slightly higher than the 118 FPS average at 1920x1080 with Ultra settings. This suggests the higher resolution at High quality is a better trade-off.

Settings Recommendations

The measured data points to High settings as the sweet spot for this combination of CPU and GPU. At 1080p, High delivers 187.5 FPS, which is sufficient for most high-refresh displays while still offering better visual quality than Medium (237.2 FPS) or Low (298.8 FPS) — those lower presets sacrifice too much visual fidelity for frame rates that exceed what most monitors can display. At 1440p, High produces 119.3 FPS, ideal for 120 Hz panels, and it remains far ahead of Ultra’s 75.6 FPS. At 4K, High is the only preset that clears 60 FPS at 61.7 FPS, making it the default choice for 4K play.

For players who prioritize maximum frame rates over visuals, Medium settings at 1080p (237.2 FPS) or Low at 1440p (188 FPS) are the best alternatives. Ultra settings are difficult to recommend: at every resolution, they cost more than 40% of the frame rate compared to High — 187.5 to 118 FPS at 1080p, 119.3 to 75.6 FPS at 1440p, and 61.7 to 41 FPS at 4K — without delivering a proportional visual improvement in most Minecraft scenarios. The data clearly favors High as the balanced choice across all tested resolutions.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across the board. Low settings average 298.8 FPS, Medium averages 237.2 FPS, High averages 187.5 FPS, and Ultra averages 118 FPS. The gap between Low and Medium is 61.6 FPS, while the gap between Medium and High is 49.7 FPS, and the gap between High and Ultra is 69.5 FPS. This shows diminishing returns are not linear — the jump from High to Ultra is the most punishing in absolute terms.

At 2560x1440, the averages drop across all presets. Low averages 188 FPS, Medium averages 152.7 FPS, High averages 119.3 FPS, and Ultra averages 75.6 FPS. The drop from 1080p to 1440p is consistent: Low loses 110.8 FPS, Medium loses 84.5 FPS, High loses 68.2 FPS, and Ultra loses 42.4 FPS. Notably, the absolute loss shrinks as settings increase, because lower-quality presets are more frame-rate-bound and thus more sensitive to resolution scaling.

At 3840x2160, the system falls below 100 FPS on every preset. Low averages 100.5 FPS, Medium averages 76.2 FPS, High averages 61.7 FPS, and Ultra averages 41 FPS. The drop from 1440p to 4K is severe: Low loses 87.5 FPS, Medium loses 76.5 FPS, High loses 57.6 FPS, and Ultra loses 34.6 FPS. At this resolution, even Low settings cannot maintain the frame rates seen at 1440p Medium, which highlights the GPU’s limits.

GPU Role

The NVIDIA GeForce GTX 1660 SUPER is the decisive factor in this system’s frame rates, especially at 1440p and 4K. It has 6 GB of GDDR6 memory on a 192-bit bus, providing 336.0 GB/s of bandwidth. Its base clock is 1530 MHz with a boost clock of 1785 MHz, and it carries 1408 shading units, 88 texture mapping units, and 48 ROPs. The GPU’s 55th percentile ranking among all GPUs, with an average benchmark score of 14286, places it in the mid-range, and the nearest rivals are integrated or entry-level parts like the AMD Radeon RX Vega 11 (deltaPct -0.2) and Intel Iris Xe MAX Graphics (deltaPct -0.2).

The measured FPS data aligns with this mid-range positioning. At 1080p, the GTX 1660 SUPER has enough raw throughput to feed high-refresh displays, but at 4K the 6 GB VRAM and 192-bit bus become constraints. The 41 FPS at 4K Ultra and 61.7 FPS at 4K High suggest that the GPU is hitting memory bandwidth limits, as the frame rate drops disproportionately compared to the resolution increase. The GPU’s FP32 performance of 5.027 TFLOPS and texture rate of 157.1 GTexel/s are adequate for Minecraft’s block-based rendering, but they are not enough to sustain high frame rates at 4K with heavy settings.

CPU Role

The AMD Ryzen 9 5900X provides more than enough processing power for Minecraft: Java Edition, which is evident from the high frame rates at 1080p. This CPU has 12 cores and 24 threads, with a base clock of 3.70 GHz and a boost clock of 4.80 GHz. It uses the Zen 3 architecture on a 7 nm process, with 64 MB of L3 cache. Its 90th percentile ranking among all CPUs, with an average benchmark score of 39453, puts it in the top tier, and the nearest rivals include the AMD Ryzen 7 PRO 8845HS (deltaPct -0.7) and Intel Core i7-13700 (deltaPct -1).

The CPU’s single-thread performance is particularly relevant for Minecraft, which is largely single-threaded in its core simulation. The Cinebench R23 single-core score of 4680 and Geekbench single-core score of 2202 indicate strong per-core performance, which explains why the system can achieve 298.8 FPS at 1080p Low without the CPU becoming a bottleneck. The multi-threaded scores, such as Cinebench R23 multicore at 33150 and Passmark multithread at 39002, show that the CPU has massive headroom for background tasks or heavily modded instances. The 64 MB L3 cache helps with world data, and the dual-channel DDR4 memory bandwidth of 51.2 GB/s is sufficient for this game. In this pairing, the CPU is never the limiting factor — the GPU starts to struggle first at 1440p and 4K, while the 5900X continues to deliver frame rates that exceed what the GTX 1660 SUPER can output.
