Roblox

The Intel Core i5-9400 and AMD Radeon RX 9060 combination ranks 1,729th out of 3,010 tested combos for Roblox, placing it in the lower-middle tier of the database. This rank is primarily constrained by the aging six-core processor, which sits at the 47th percentile among all CPUs, while the GPU holds a stronger 59th percentile position. The pairing produces playable frame rates across all tested settings, but the data indicates the CPU becomes the limiting factor at lower resolutions, where the GPU's headroom is left on the table.

How This Combo Ranks

The combo's 1,729th place out of 3,010 tested combinations reflects a system that is capable but not exceptional for Roblox. The ranking suggests that roughly 57% of tested combos deliver better performance, which aligns with the component mix of a mid-range GPU paired with an older mainstream CPU. The GPU's 59th percentile ranking among all GPUs is notably higher than the CPU's 47th percentile, indicating the processor is the weaker link in this pairing for this game.

Benchmark results for the individual components reinforce this assessment. The Radeon RX 9060 posts an average benchmark score of 16,014, placing it within 0.7% of the NVIDIA GeForce RTX 3060 Ti, which scores 16,129. The i5-9400's average score of 2,254 puts it within 0.2% of the Intel Core i7-1068NG7, which scores 2,259, and within 0.3% of the Intel Core i7-10710U at 2,248. These tight margins show the CPU is competitive with its immediate peers, but those peers are themselves older or lower-power parts.

The measured frame rates show the combo does not struggle in absolute terms. At 1080p Ultra, the system produces 221 FPS on average, and at 4K High it still manages 103 FPS. The ranking therefore reflects relative standing against other combinations in the database rather than a playability problem, as the frame rates are well above typical display refresh rates even at the most demanding settings tested.

GPU Role

The AMD Radeon RX 9060 brings 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The GPU's architecture is RDNA 4.0 on a 4 nm process, with a base clock of 1700 MHz and a boost clock of 2990 MHz. The memory clock runs at 2250 MHz, which the fact pack lists as 18 Gbps effective. These specifications place the card firmly in the mid-range tier, and its benchmark scores confirm this positioning.

The GPU's 3DMark Steel Nomad DX12 score of 3,322 and PassMark G3D score of 17,631 are consistent with its 59th percentile rank. Its nearest rival, the RTX 3060 Ti, scores 1% higher on average, while the Radeon RX 7700 scores 1% lower. In Roblox specifically, the GPU's capabilities are more than sufficient, as even the most demanding setting tested (4K Ultra) produces 83 FPS, which is above the 60 FPS threshold most players consider smooth.

The GPU's memory configuration of 8 GB is adequate for Roblox's relatively modest texture requirements. The 288.0 GB/s bandwidth is not taxed heavily by this game, as evidenced by the small performance gaps between settings at each resolution. At 1440p, the difference between Low and Ultra settings is 79 FPS (226 vs 147), while at 1080p the same comparison shows a 117 FPS gap (338 vs 221). These differences are more attributable to the CPU's ability to feed frames at lower resolutions than to any GPU memory limitation.

Resolution Scaling

The frame rate scaling across resolutions reveals a system that becomes increasingly CPU-bound as resolution drops. At 1080p High, the combo delivers 272 FPS, which drops to 182 FPS at 1440p High and 103 FPS at 4K High. This represents a 33% reduction from 1080p to 1440p and a 62% reduction from 1080p to 4K. The scaling is not linear, which is typical for a system where the CPU cannot keep up with the GPU at lower resolutions.

The Low settings tell a similar story. At 1080p Low, the system reaches 338 FPS, but at 1440p Low it drops to 226 FPS, and at 4K Low it falls to 128 FPS. The 4K Low result is particularly telling: the GPU is clearly capable of rendering this game at 4K, but the CPU is holding back the frame rate even at the lowest settings. The gap between 1080p Low (338 FPS) and 1440p Low (226 FPS) is 112 FPS, while the gap between 1440p Low and 4K Low is 98 FPS, showing that the CPU bottleneck persists across all resolutions.

Ultra settings show the most dramatic scaling. At 1080p Ultra, the system produces 221 FPS, dropping to 147 FPS at 1440p Ultra and 83 FPS at 4K Ultra. The 4K Ultra result is 62% lower than the 1080p Ultra result, which is a larger drop than the High setting's 62% reduction. This suggests that the Ultra preset adds enough GPU workload that the graphics card becomes more of a limiting factor at 4K, though the CPU still constrains performance at lower resolutions. The data indicates the i5-9400 is the primary bottleneck at 1080p and 1440p, while the RX 9060 becomes more relevant at 4K.

Settings Recommendations

The measured data shows the Medium preset offers the best balance of performance and visual quality for this combo. At 1080p Medium, the system achieves 308 FPS average with a minimum of 262 FPS and a maximum of 354 FPS. The minimum frame rate of 262 FPS is well above any display's refresh rate, ensuring smooth gameplay without drops. At 1440p Medium, the average drops to 205 FPS with a minimum of 175 FPS, still providing a comfortable margin above 144 Hz displays.

The High preset is also viable, delivering 272 FPS at 1080p and 182 FPS at 1440p. The gap between Medium and High is 36 FPS at 1080p and 23 FPS at 1440p, which is modest and may justify the visual upgrade for players with high-refresh monitors. However, the Ultra preset shows diminishing returns: at 1080p, Ultra produces 221 FPS, which is 87 FPS lower than Medium, and at 1440p, Ultra drops to 147 FPS, which is 58 FPS lower than Medium.

For 4K gaming, the High preset is the recommended choice, delivering 103 FPS. The Medium preset at 4K produces 116 FPS, but the minimum frame rate of 99 FPS indicates occasional dips below 100 FPS. The Ultra preset at 4K drops to 83 FPS, which remains playable but leaves less headroom. The Low preset at 4K produces 128 FPS, but the visual compromise is substantial for a game where the Medium preset already delivers high frame rates. Players targeting 4K should use High settings, while those at 1080p or 1440p can comfortably use Medium or High depending on their refresh rate preferences.

CPU Role

The Intel Core i5-9400 provides six cores and six threads with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. The processor is built on the Coffee Lake architecture using a 14 nm process, with 9 MB of shared L3 cache. Its memory support is DDR4 in a dual-channel configuration, providing 42.7 GB/s of bandwidth. The CPU's 65 W TDP and PCIe Gen 3 with 16 lanes make it a conventional desktop part from the 2018 era.

The CPU's benchmark results show it is a modest performer by current standards. Its Cinebench R23 scores are 6,629 for multi-core and 935 for single-core, while Geekbench scores are 5,141 multi-core and 1,389 single-core. The 47th percentile ranking among all CPUs places it squarely in the middle of the pack, and its nearest rivals all score within 0.4% of its average, indicating a cluster of similarly performing processors.

In Roblox, the CPU's six cores without hyper-threading are sufficient for the game's workload, but the processor's single-thread performance limits frame rates at lower resolutions. The data shows that at 1080p, the difference between Low and Ultra settings is 117 FPS, which is a 53% reduction. This large gap indicates the CPU cannot maintain its maximum frame rate when the GPU adds more work, even though the GPU is capable of rendering the scene faster. At 4K, the same comparison shows a 45 FPS difference, or 35%, because the GPU workload increases and the CPU has more time to feed frames.

The i5-9400's aging architecture is the main reason this combo ranks at 1,729th out of 3,010. The GPU is a modern part with the 59th percentile ranking, but the CPU's 47th percentile ranking drags the overall combination down. Players with high-refresh monitors at 1080p will see frame rates above 220 FPS on Ultra, but the CPU prevents the system from reaching the 338 FPS that the Low preset can achieve. For Roblox specifically, this CPU is adequate, but it does not allow the RX 9060 to fully stretch its legs at lower resolutions.
