Minecraft: Java Edition

Minecraft: Java Edition is notoriously CPU-bound, and this dataset for the AMD Ryzen 5 4600G paired with an NVIDIA GeForce RTX 4090 confirms that dynamic in a dramatic way. The measured frame rates across resolutions and settings reveal a system where the graphics card is rarely the limiting factor, and the processor’s single-threaded performance dictates the ceiling. This analysis breaks down the measured FPS data to show what you can expect from this specific combination, how to configure it, and where the real bottlenecks lie.

Resolution Scaling

The frame rate drop from 1080p to 4K is surprisingly shallow, which is a clear indicator that the CPU is the primary constraint. At High settings, the average FPS moves from 421.8 at 1920x1080 to 359.7 at 2560x1440, and then to 185.2 at 3840x2160. The 1440p to 4K transition represents a 48.5% performance loss, while the 1080p to 1440p step only costs about 14.7%. This pattern is typical of a CPU-bound scenario: as resolution increases, the GPU has more work to do, but the CPU still has to feed it the same number of draw calls and game logic updates.

The Low preset tells an even clearer story. At 1920x1080, the system pushes 497.5 FPS, which drops to 429.0 at 1440p and 297.6 at 4K. The 4K result is still remarkably high, but the scaling is not linear with pixel count. If the RTX 4090 were the limiter, you would expect a much steeper decline at 4K, especially with its 24 GB of GDDR6X memory and 1.01 TB/s bandwidth. Instead, the data suggests that even at 4K, the Ryzen 5 4600G’s Zen 2 architecture, with its 3.70 GHz base clock and 4.20 GHz boost clock, is holding the card back.

The Ultra preset shows the most significant resolution sensitivity, with scores falling from 349.9 at 1080p to 221.7 at 1440p and finally 115.4 at 4K. This indicates that Ultra settings introduce enough GPU load (likely through rendering distance and shadow quality) to start shifting the balance toward the graphics card. Still, the fact that 4K Ultra manages 115.4 FPS average shows that the RTX 4090 is never truly idle, but the CPU’s 6 cores and 12 threads are not enough to keep it fully saturated in lighter settings.

Settings Recommendations

The measured data points to Medium as the sweet spot for this pairing, particularly if you are targeting high refresh rates. At 1920x1080, Medium delivers 459.6 FPS, which is only 7.6% lower than Low’s 497.5 FPS but a substantial 9.0% higher than High’s 421.8 FPS. The jump from Medium to High at 1080p costs you 37.8 FPS, which is a meaningful drop for competitive play. At 1440p, Medium hits 390.6 FPS, still far above the 360 Hz class of monitors, and it is only 8.4% behind Low’s 429.0 FPS.

For 4K, the choice is more nuanced. High settings at 185.2 FPS is playable, but Ultra at 115.4 FPS is the only preset that dips below 144 FPS. If you have a 144 Hz 4K panel, High is the practical ceiling, as it provides a 60.5% performance advantage over Ultra. Low at 4K is technically the fastest at 297.6 FPS, but the visual compromises in Minecraft are likely not worth the extra frames when Medium still offers 238.0 FPS. The data suggests that Medium is the default recommendation for this build, as it balances the CPU’s single-threaded limitations against the GPU’s raw power without hitting the steep diminishing returns seen at Ultra.

GPU Role

The RTX 4090’s role in this benchmark is more about providing headroom than being taxed. With a boost clock of 2520 MHz and 16384 shading units, the card is capable of massive throughput, but Minecraft’s Java engine often fails to utilize it fully. The 24 GB of VRAM is irrelevant here, as the game’s texture requirements are modest even at Ultra. The measured FPS differences between presets at the same resolution are more attributable to CPU-side draw calls than to GPU fill rate.

The GPU’s 82.58 TFLOPS of FP32 performance and 1,290.2 GTexel/s texture rate are not the bottlenecks in any of the 12 measured rows. Instead, the data shows that the RTX 4090 is waiting on the CPU. The near-500 FPS results at 1080p Low are a testament to the card’s ability to process frames as fast as the Ryzen 5 4600G can generate them. However, the fact that 4K Ultra only reaches 115.4 FPS, despite the card’s 91st percentile ranking among all GPUs, underscores that this is a CPU-limited pairing. The GPU’s 24 GB of GDDR6X memory and 384-bit bus width are simply overkill for a title that does not scale with those resources.

Measured FPS Breakdown

At 1920x1080, the full spectrum of settings shows a clear hierarchy. Low leads at 497.5 FPS, followed by Medium at 459.6, High at 421.8, and Ultra at 349.9. The delta between Low and Ultra is 147.6 FPS, or 29.7% of the Low score. This is a tight band, indicating that even the heaviest preset cannot fully engage the RTX 4090. The 1080p results are all above 300 FPS, meaning any modern high-refresh monitor will be saturated.

At 2560x1440, the same order persists but with compressed margins. Low drops to 429.0 FPS, Medium to 390.6, High to 359.7, and Ultra to 221.7. The gap between Low and Ultra widens to 207.3 FPS, but the relative drop from 1080p is smaller for Low (13.8%) than for Ultra (36.6%). This suggests that Ultra at 1440p is starting to engage the GPU more, but the CPU still limits the lower presets.

At 3840x2160, the scaling becomes more pronounced. Low is 297.6 FPS, Medium is 238.0, High is 185.2, and Ultra is 115.4. The 4K Ultra result is the only one below 144 FPS in the entire dataset. The drop from High to Ultra at 4K is 69.8 FPS, a 37.7% reduction, which is the largest single-step penalty across all resolutions. This indicates that Ultra settings at 4K finally push the RTX 4090 into a position where its performance matters, but the CPU still prevents it from reaching the 200 FPS territory seen at lower resolutions.

FAQ

Q: Is this system better for 1080p or 4K gaming in Minecraft?

A: The data shows 1080p produces the highest frame rates, with Low hitting 497.5 FPS versus 297.6 at 4K. However, even 4K High at 185.2 FPS is above 144 Hz, so the system is viable for 4K, but it is clearly optimized for lower resolutions.

Q: Why does the RTX 4090 not produce higher FPS at 4K Ultra?

A: The 115.4 FPS result at 4K Ultra is limited by the Ryzen 5 4600G’s single-threaded performance. The CPU’s 3.70 GHz base clock and 4.20 GHz boost clock are insufficient to feed the GPU’s 16384 shading units at maximum load.

Q: What is the best preset for competitive play?

A: Low at 1080p offers the highest average at 497.5 FPS, but Medium at 459.6 FPS is only 7.6% slower and likely offers better visual clarity for spotting enemies. The trade-off is minimal.

Q: Does the 24 GB VRAM matter for Minecraft?

A: No. The measured FPS differences are not correlated with VRAM usage. The 24 GB GDDR6X is unused overhead for this title, as the game’s textures do not scale to that capacity.

Q: How does the CPU compare to its nearest rivals in this context?

A: The Ryzen 5 4600G has an average benchmark score of 17489, which is within 0.1% of the Intel Core i5-12450H (17475) and 0.8% below the Intel Core i3-14100T (17636). This indicates it is a mid-pack performer, and the FPS data reflects that.

Q: Is the 4K Ultra result playable?

A: At 115.4 FPS, it is above 60 FPS and suitable for most single-player scenarios. However, it is below 144 Hz, so competitive players should use High at 185.2 FPS for smoother motion.

CPU Role

The AMD Ryzen 5 4600G is the clear bottleneck in this configuration. With 6 cores and 12 threads based on Zen 2 architecture, it has a base clock of 3.70 GHz and a boost clock of 4.20 GHz. Its Cinebench R23 single-core score of 1919 and multi-core score of 13593 place it in the 75th percentile of all CPUs. However, Minecraft’s Java engine is heavily reliant on single-thread performance, and the 4600G’s 3dmark single-thread score of 726 is modest.

The measured FPS data shows that the CPU’s limits are hit early. At 1080p Low, the system reaches 497.5 FPS, but this is likely the ceiling for this processor, not the GPU. The 3dmark 2-thread score of 1430 indicates that the CPU can handle two threads reasonably well, but the game’s primary thread is the limiting factor. The nearest rivals, such as the Intel Core i3-13100F with a deltaPct of -1.0% (average score 17665), would likely produce similar or slightly better FPS due to better single-thread performance, but the data here is specific to this CPU.

The 8 MB of shared L3 cache is another factor. While it is sufficient for many tasks, Minecraft’s world generation and entity processing can benefit from larger caches. The 4600G’s cache is not a bottleneck in the measured rows, but it does not help push past the 500 FPS barrier. The CPU’s 65 W TDP and 7 nm process are efficient, but efficiency does not translate to raw FPS in this title. The conclusion is straightforward: the RTX 4090 is overkill for this CPU in Minecraft, and the Ryzen 5 4600G is the component that defines the performance envelope.
