Minecraft

Minecraft with an Intel Core Ultra 5 225 and AMD Radeon RX 6650 XT produces a wide spread of frame rates depending on resolution and settings. The data shows a system that is clearly capable of high refresh rates at mainstream resolutions but starts to show its limits when pushed to 4K Ultra. The following analysis breaks down the measured performance to help determine the best way to configure this combo.

Resolution Scaling

The frame rate drop from 1080p to 4K is dramatic and reveals a shift in the bottleneck. At 1080p Low, the combo delivers 405 FPS average. Moving to 1440p Low drops that to 255 FPS, a reduction of 150 FPS or roughly 37%. At 4K Low, the average falls further to 133 FPS. The scaling from 1440p to 4K at Low settings shows a 122 FPS drop, which is a larger absolute loss than the 1080p to 1440p step. This indicates that the GPU is becoming the primary limiting factor as the pixel count rises.

The pattern persists across other settings. At Medium settings, the average FPS goes from 321 at 1080p, to 202 at 1440p, to 106 at 4K. The percentage drop from 1440p to 4K is about 48%, while the drop from 1080p to 1440p is about 37%. This steeper decline at higher resolutions is a classic sign of a GPU-bound scenario. The RX 6650 XT, with its 8 GB of memory and 128-bit bus, is being tasked with filling increasingly more pixels.

At High settings, the averages are 254 FPS at 1080p, 161 FPS at 1440p, and 84 FPS at 4K. The gap between 1080p and 1440p is 93 FPS, while the gap between 1440p and 4K is 77 FPS. While the absolute numbers differ, the trend is consistent: the GPU's workload scales non-linearly with resolution. The most demanding scenario, 4K Ultra, yields just 52 FPS average. This is a 353 FPS drop from the 1080p Low result, showing a massive performance range within a single game.

The data suggests that for 1080p and 1440p gaming, this CPU-GPU pairing is well-balanced. The CPU has enough headroom to feed the GPU at these resolutions. However, at 4K, the GPU's raw throughput becomes the wall. The 133 FPS at 4K Low versus the 52 FPS at 4K Ultra underscores how much overhead is consumed by higher graphical fidelity. Users targeting 4K will need to make significant compromises in settings to maintain playable frame rates.

Settings Recommendations

For 1080p, the measured results show that even the Ultra preset is highly playable. The 159 FPS average at 1080p Ultra is well above the threshold for smooth gameplay on high refresh rate monitors. There is no reason to drop below High settings at this resolution, as the 254 FPS average at High is already far beyond what most displays can show. The Medium preset at 321 FPS and Low at 405 FPS are technically impressive but offer diminishing returns for most users, as the visual quality loss is not justified by the frame rate increase.

At 1440p, the Ultra preset produces a 100 FPS average, which is still smooth for most titles. However, the High preset at 161 FPS provides a more comfortable margin for 144Hz displays. The data suggests that High is the sweet spot for 1440p, offering a significant boost over Ultra without a major visual penalty. The Medium preset at 202 FPS is an option for competitive play, but the jump from Medium to High is only a 41 FPS loss, making High the more balanced choice.

At 4K, the situation changes. The Ultra preset at 52 FPS is borderline for a game like Minecraft, which can be sensitive to input latency. The High preset at 84 FPS is a much better experience, and the Medium preset at 106 FPS is even better. The Low preset at 133 FPS is the only way to achieve a high refresh rate experience at 4K, but it comes with a substantial visual downgrade. For the best balance of visual quality and smoothness at 4K, the Medium preset appears to be the recommended choice, as it provides an average FPS in the triple digits while retaining some graphical features.

The measured minimum FPS data supports these recommendations. At 1440p Medium, the minimum FPS is 172, which is a strong guarantee of consistent performance. At 4K Medium, the minimum FPS is 90, which is still acceptable, but the margin for error is smaller. The Ultra presets have no recorded minimum FPS, but the average values suggest they are more likely to produce stutter or frame drops in complex scenes.

GPU Role

The AMD Radeon RX 6650 XT is the decisive factor in this game's higher-resolution performance. Its specifications, including 2048 shading units, 128 texture mapping units, and 64 raster output units, are modest by modern standards. The GPU's memory configuration of 8 GB GDDR6 on a 128-bit bus provides 280.3 GB/s of bandwidth, which is adequate for 1080p and 1440p but becomes a constraint at 4K with higher presets. The boost clock of 2635 MHz and game clock of 2410 MHz are high, but they cannot compensate for the limited memory bandwidth when rendering large view distances.

The GPU's compute capability of 10.79 TFLOPS is the raw throughput that drives the FPS numbers. The results show that this throughput is sufficient for 1080p and 1440p gaming, with even Ultra presets yielding playable frame rates. However, at 4K, the GPU is clearly overworked. The 52 FPS average at 4K Ultra indicates that the pixel fill rate and memory bandwidth are insufficient for that workload. The pixel rate of 168.6 GPixel/s and texture rate of 337.3 GTexel/s are the theoretical limits, and the measured results show the GPU approaching those limits at 4K.

The GPU's performance percentile of 65 versus all GPUs places it in the mid-range tier. Its average benchmark score of 19765 is closely matched by its nearest rivals, including the NVIDIA Tesla K40m and AMD FirePro W7000, which are older professional cards. This context explains why the RX 6650 XT performs well at 1080p but struggles at 4K. It is a solid 1080p and capable 1440p card, but it is not designed for 4K Ultra gaming. The 8 GB of VRAM is also a limiting factor, as modern games with high-resolution textures can exceed this capacity, leading to texture streaming issues.

Measured FPS Breakdown

The following table summarizes the measured average FPS for each resolution and settings combination:

• 1920x1080: Low 405, Medium 321 (min 272, max 369), High 254, Ultra 159
• 2560x1440: Low 255, Medium 202 (min 172, max 233), High 161, Ultra 100
• 3840x2160: Low 133, Medium 106 (min 90, max 122), High 84, Ultra 52

At 1080p, the progression from Low to Ultra shows a steady decline. The step from Low to Medium is 84 FPS, from Medium to High is 67 FPS, and from High to Ultra is 95 FPS. The largest drop is between High and Ultra, indicating that the Ultra preset includes features that are disproportionately expensive on this GPU. The 1080p Medium result of 321 FPS with a minimum of 272 FPS shows excellent consistency, with the maximum FPS reaching 369.

At 1440p, the drops are more pronounced. Low to Medium is 53 FPS, Medium to High is 41 FPS, and High to Ultra is 61 FPS. The Ultra preset at 100 FPS is the first time this combo dips below the 120 FPS mark at 1440p. The Medium preset's minimum of 172 FPS is still very high, suggesting that the GPU has enough headroom to handle most scenes without dropping below the average.

At 4K, the scaling is severe. Low to Medium is 27 FPS, Medium to High is 22 FPS, and High to Ultra is 32 FPS. The Ultra preset at 52 FPS is barely playable, and the High preset at 84 FPS is the minimum recommended for a smooth experience. The Medium preset at 106 FPS is the best option for those who want a balance of quality and performance, with a minimum FPS of 90 that should prevent most noticeable stutters. The Low preset at 133 FPS is the only way to get a high refresh rate experience at 4K, but it sacrifices nearly all graphical enhancements.

How This Combo Ranks

The combo rank for this CPU-GPU pairing in Minecraft is 748 out of 1176 tested combinations. This places it in the lower-middle portion of the ranking, which is somewhat surprising given the high frame rates at 1080p. The rank is likely dragged down by the GPU's performance at 4K, where it falls behind many other combinations. The CPU's performance percentile of 85 is high, but the GPU's percentile of 65 is lower, creating an imbalance that hurts the overall ranking.

The rank of 748 suggests that while this combo is perfectly playable in most scenarios, there are many other pairings that deliver better overall performance across all resolutions. The GPU is the weaker link, and its limitations at 4K are the primary reason for the rank. At 1080p and 1440p, this combo would likely rank much higher, but the comprehensive ranking includes 4K results, which penalize the RX 6650 XT.

Compared to other combos, the data shows that this pairing is best suited for 1080p high refresh rate gaming. The 254 FPS average at 1080p High is a strong result that would satisfy most gamers. At 1440p, the 161 FPS average at High is also competitive. The rank of 748 is a reminder that the RX 6650 XT is a mid-range GPU, and pairing it with a high-end CPU like the Core Ultra 5 225 does not boost its 4K capabilities. The CPU is not the limiting factor in this combo; the GPU is.

CPU Role

The Intel Core Ultra 5 225 provides the compute foundation for this combo. With 10 cores and 10 threads, it has sufficient parallelism for modern games. The base clock of 3.30 GHz and boost clock of 4.90 GHz are strong for single-threaded performance, which is critical for Minecraft's primary game logic. The CPU's L3 cache of 20 MB shared and L2 cache of 3 MB per core help reduce memory latency, which is beneficial for the game's block-based world generation.

The CPU's benchmark results show it is a capable processor. Its Cinebench R23 multi-core score of 25891 and single-core score of 3655 indicate a strong balance of multi-threaded and single-threaded performance. The PassMark single-thread score of 4412 is particularly relevant for Minecraft, as the game's main thread often becomes a bottleneck at high frame rates. However, the measured FPS data shows that this CPU is not the bottleneck at any resolution in this test.

The CPU's percentile versus all CPUs is 85, placing it well above average. Its average benchmark score of 36938 is nearly identical to its nearest rival, the AMD Ryzen 5 5600F, with a delta of 0%. This means the Core Ultra 5 225 performs essentially the same as the Ryzen 5 5600F in general benchmarks. The CPU's role in this combo is to feed the GPU with enough data to maintain the high frame rates seen at 1080p and 1440p.

The evidence of the CPU's non-limiting role is the scaling pattern. At 1080p Low, the 405 FPS result shows that the CPU can handle very high frame rates without being a constraint. If the CPU were the bottleneck, the frame rate would plateau regardless of settings or resolution. Instead, the frame rates scale predictably with resolution and settings, confirming that the GPU is the limiting factor. The CPU's 10 threads are sufficient for Minecraft, which typically uses only a few threads, leaving the rest of the CPU's capacity available for background tasks. The high boost clock of 4.90 GHz ensures that the primary game thread runs as fast as possible, preventing CPU-related stutters.
