Roblox

Roblox is a uniquely scalable title, and the data for the Intel Core i5-13400F paired with the NVIDIA GeForce GTX 1650 shows a system that is clearly bound by the graphics card at higher resolutions. The measured frames per second (FPS) reveal a predictable pattern: the gap between 1080p and 4K is substantial, but the CPU keeps the game playable even at the most demanding settings. This combination ranks in the 1751st position out of 1800 tested combos, placing it in the lower percentile of systems, yet the raw numbers indicate it still delivers a smooth experience for the majority of Roblox's content.

Resolution Scaling

The FPS drop from 1920x1080 to 3840x2160 is significant, but not catastrophic. At High settings, the system averages 119.1 FPS at 1080p, drops to 76.8 FPS at 1440p, and then falls to 47.6 FPS at 4K. This represents a 60% reduction in frame rate from 1080p to 4K, which clearly illustrates that the GTX 1650 is the limiting component. The scaling is consistent with a GPU that has a 128-bit memory bus and 4 GB of GDDR5 memory, as the pixel fill rate requirements quadruple when moving from 1440p to 4K.

The story changes slightly when looking at the Low preset. At 1080p Low, the system hits 149.4 FPS, which is a strong indicator that the CPU can push well beyond the 144 Hz mark for esports-style play. At 1440p Low, the average stays high at 95.7 FPS, and even at 4K Low, it maintains a respectable 54.3 FPS. The delta between Low and Ultra at 4K is 18.2 FPS (54.3 vs 36.1), which is a smaller absolute gap than at 1080p, where the difference is 54.8 FPS (149.4 vs 94.6). This narrowing gap at higher resolutions confirms that the GPU is saturated, while the i5-13400F has headroom to spare.

GPU Role

The GTX 1650 is a Turing-architecture part built on a 12 nm process, with a die size of 200 mm² and 4,700 million transistors. Its memory configuration is the most critical factor in Roblox: 4 GB of GDDR5 on a 128-bit bus yields a bandwidth of 128.1 GB/s. The base clock is 1485 MHz with a boost of 1665 MHz, and the card has a pixel rate of 53.28 GPixel/s. These specifications explain why the card performs adequately at 1080p but struggles to maintain high frame rates at 4K, as the texture rate of 93.24 GTexel/s becomes a bottleneck.

The GPU's benchmark scores reinforce this analysis. Its Passmark G3D score is 7880, placing it in the 43rd percentile of all GPUs. This is a low-to-mid range result, but the card's performance in Roblox is relatively better than its raw compute would suggest, because the game is not heavily dependent on the FP32 throughput of 2.984 TFLOPS. The card's nearest rivals in the benchmark database are the NVIDIA GeForce RTX 3050 A Mobile (deltaPct -0.4) and the AMD Radeon 550X (deltaPct -0.4), which shows that the GTX 1650 sits in a performance tier where small clock differences matter more than architectural changes.

Settings Recommendations

The measured data points to the Medium preset as the optimal balance for this combo. At 1080p Medium, the system produces 135 FPS, which is only 14.4 FPS lower than Low and 24.4 FPS higher than Ultra. At 1440p Medium, the average is 88.1 FPS, which is still smooth for most displays, and it is only 7.6 FPS behind Low. The jump from Medium to High at 1440p costs 11.3 FPS (88.1 to 76.8), which may not be worth the visual fidelity gain for players who prioritize frame rate.

For 4K users, the choice is stark. Low settings yield 54.3 FPS, which is playable, but Medium drops to 51.8 FPS, and High falls to 47.6 FPS. Ultra is not recommended at this resolution, as it produces just 36.1 FPS, which is below the threshold for a comfortable experience in a game that can have fast camera movements. The data suggests that 4K is only viable on Low for this GPU, while 1440p is the sweet spot for a mix of quality and performance. At 1080p, all presets are playable, but Medium offers the best combination of visual clarity and headroom for frame drops.

How This Combo Ranks

The i5-13400F + GTX 1650 combination ranks 1751 out of 1800 tested combos in Roblox. This places it in the bottom 3% of systems, which is expected given the GPU's age and market position. However, the ranking does not tell the whole story. The CPU is not the limiting factor; the i5-13400F has a Passmark multithread score of 25032 and a single-thread score of 3634, placing it in the 82nd percentile of all CPUs. Its nearest rivals include the Intel Core i7-13620H (deltaPct 0.1) and the AMD Ryzen 5 5600X3D (deltaPct -0.5), which shows the CPU is punching well above its weight class.

The issue is the GPU pairing. The GTX 1650's average benchmark score is 8713, and its nearest rivals are the RTX 3050 A Mobile (deltaPct -0.4) and the Quadro P2200 (deltaPct 0.5). This suggests that the GPU is performing as expected for its tier. The combo rank of 1751 is a direct consequence of the GPU's 43rd percentile standing. If the same CPU were paired with a higher-tier GPU, the rank would improve dramatically, as Roblox is largely GPU-bound at the resolutions tested. For a builder looking at this data, the takeaway is that the CPU has longevity, but the GPU is the ceiling for performance.

FAQ

Q: Can this system run Roblox at 1080p 144Hz?

A: Yes, on Low and Medium settings. The measured average at 1080p Low is 149.4 FPS, and at Medium it is 135 FPS. High settings produce 119.1 FPS, which is close to the 144Hz mark but may not sustain it in heavy scenes.

Q: Is the CPU or GPU the bottleneck in this combo?

A: The GPU is the clear bottleneck. The CPU has a Passmark multithread score of 25032 and ranks in the 82nd percentile, while the GPU's Passmark G3D score is 7880, ranking in the 43rd percentile. The FPS scaling from 1080p to 4K confirms this, as frame rates drop by over 60% at higher resolutions.

Q: What is the best resolution for this system?

A: 1440p offers the best balance. At Medium settings, the average is 88.1 FPS, which is smooth and looks significantly better than 1080p. 4K is only playable on Low settings, with 54.3 FPS average.

Q: How does the GTX 1650 compare to its nearest rivals in the database?

A: The GTX 1650 has an average benchmark score of 8713. Its nearest rival, the NVIDIA GeForce RTX 3050 A Mobile, scores 8746, which is a deltaPct of -0.4. The AMD Radeon 550X scores 8749, also a deltaPct of -0.4. This means the GTX 1650 is essentially tied with these cards.

Q: Should I use Ultra settings on this system?

A: Only at 1080p. Ultra at 1080p yields 94.6 FPS, which is playable. At 1440p Ultra, the average drops to 66.2 FPS, and at 4K Ultra it falls to 36.1 FPS, which is not recommended.

Q: Does the 4 GB VRAM limit performance in Roblox?

A: The data suggests it does at higher resolutions. The 4 GB GDDR5 memory with a bandwidth of 128.1 GB/s is sufficient for 1080p, but the 60% FPS drop from 1080p to 4K indicates that memory bandwidth and capacity are strained at higher pixel counts.

Measured FPS Breakdown

The following table details the exact measured average FPS for each resolution and settings preset:

| Resolution | Settings | Avg FPS |

|------------|----------|---------|

| 3840x2160 | High | 47.6 |

| 3840x2160 | Low | 54.3 |

| 3840x2160 | Medium | 51.8 |

| 3840x2160 | Ultra | 36.1 |

| 2560x1440 | High | 76.8 |

| 2560x1440 | Low | 95.7 |

| 2560x1440 | Medium | 88.1 |

| 2560x1440 | Ultra | 66.2 |

| 1920x1080 | High | 119.1 |

| 1920x1080 | Low | 149.4 |

| 1920x1080 | Medium | 135 |

| 1920x1080 | Ultra | 94.6 |

The data confirms that the GTX 1650 can handle Roblox at 1080p with ease, providing a high-refresh experience on lower presets. At 1440p, the system remains viable for 60 FPS gaming on Medium settings, but users must be prepared to lower settings at 4K to maintain playable frame rates. The i5-13400F's strong single-thread performance, evidenced by a Geekbench single-core score of 2301, ensures that the CPU never becomes a limiting factor in this GPU-bound scenario.
