Similar Performance Alternatives

The Intel Core i5-12400F sits in a tightly packed performance cluster. Its average benchmark score of 19039 places it within a fraction of a percent of several other processors. The closest match is the AMD Ryzen 5 7535HS, which scores 19047, a negligible 0% delta. The Intel Core 3 201E trails by a hair at 19056, with a delta of -0.1%. On the other side, the Intel Core i5-1335U scores 18982, which is 0.3% behind, and the AMD EPYC 7773X also comes in at 18979, another 0.3% gap. For practical purposes, any of these CPUs would deliver near-identical frame pacing in CPU-bound scenarios, though the i5-12400F holds a slight edge over the last two options.

For the graphics side, the Intel Arc B390 is in a much more isolated position. Its benchmark score of 1482 places it in the 9th percentile of all GPUs, meaning most other graphics cards outperform it. The closest measured rival is the NVIDIA GeForce GT 520MX at 1463, which is 1.3% slower. The NVIDIA GeForce 800M follows at 1460, a 1.5% gap, then the NVIDIA GeForce GT 625 OEM at 1446 (2.5% behind) and the NVIDIA GeForce GT 710 at 1443 (2.7% behind). These rivals are all in the same performance tier, so swapping between them would produce similar frame rates, but the Arc B390 does lead this specific group.

Best Settings per Resolution

At 4K (3840x2160), the database shows that only the Low preset clears the 60 FPS threshold. It averages 64 FPS. The Medium preset comes close at 59 FPS average, but it dips to 50 FPS on the minimum frame side, so it does not hold a steady 60. High averages 52 FPS, and Ultra drops to 42 FPS. So the best settings for a smooth experience at this resolution are Low, with a recorded average of 64 FPS.

Moving to 1440p (2560x1440), the situation becomes more comfortable. The database records the Ultra preset averaging 74 FPS, which is above the playable threshold. High averages 92 FPS, Medium 104 FPS, and Low 114 FPS. Since all four presets clear 60 FPS, the best setting is Ultra, as it is the most demanding option that still maintains a 74 FPS average.

At 1080p (1920x1080), every preset is far above the threshold. Low averages 171 FPS, Medium 155 FPS, High 137 FPS, and Ultra 111 FPS. The best setting is Ultra, which delivers a 111 FPS average, leaving ample headroom.

CPU and GPU Roles

The data reveals how the balance shifts across resolutions. At 1080p, the GPU is clearly the limiting factor. The jump from Low (171 FPS) to Medium (155 FPS) is a 16 FPS drop, then to High (137 FPS) is another 18 FPS drop, and to Ultra (111 FPS) is a 26 FPS drop. These are large percentage differences relative to the resolution scaling, suggesting the workload is heavily GPU-bound at this setting level. The CPU has plenty of headroom at 1080p, as the i5-12400F is a strong performer.

At 1440p, the same pattern holds but with slightly smaller margins. Low (114 FPS) to Medium (104 FPS) is a 10 FPS drop, Medium to High (92 FPS) is 12 FPS, and High to Ultra (74 FPS) is 18 FPS. The GPU is still the dominant factor, but the CPU is starting to contribute more as the resolution increases.

At 4K, the GPU is overwhelmingly the bottleneck. The difference between Low (64 FPS) and Medium (59 FPS) is only 5 FPS, Medium to High (52 FPS) is 7 FPS, and High to Ultra (42 FPS) is 10 FPS. The absolute frame rates are much lower, and the scaling between presets is narrower, which indicates that the GPU is saturated. The CPU can process the data quickly enough, but the Arc B390 cannot push more frames at this resolution.

Looking across resolutions, the CPU matters most at 1080p, where its speed influences the high frame ceiling. At 4K, the GPU role is far more critical, as the frame rates drop below 60 FPS for all but the lowest preset. The recorded data shows a clear shift: the CPU is never the primary constraint, but the GPU becomes more limiting as resolution increases. The fact that the 4K Medium has a minimum FPS of 50 confirms that the GPU struggles to sustain frame timing under load.

The Verdict

This PC can run Roblox, but the experience depends heavily on the resolution. At 1920x1080, the system clears the 60 FPS threshold on every preset. The Ultra setting delivers 111 FPS average, which is more than sufficient. At 2560x1440, all four presets are playable, with Ultra at 74 FPS average. At 3840x2160, only the Low preset maintains a 60 FPS average, hitting 64 FPS. The Medium preset at 4K stays at 59 FPS average, but its minimum of 50 FPS means it falls below the playable threshold at times. Therefore, for a strict 60 FPS target, the verdict is: playable at 1080p and 1440p on any settings, and only playable at 4K when using Low settings.

Measured FPS Breakdown

The database provides exact measurements for each resolution and preset. At 3840x2160, the Low preset averages 64 FPS (min and max not recorded). Medium averages 59 FPS, with a minimum of 50 and a maximum of 67. High averages 52 FPS, and Ultra averages 42 FPS, with no min or max recorded for these two.

At 2560x1440, Low averages 114 FPS, Medium averages 104 FPS (min 88, max 119), High averages 92 FPS, and Ultra averages 74 FPS. The min and max for Low, High, and Ultra are not recorded.

At 1920x1080, Low averages 171 FPS, Medium averages 155 FPS (min 132, max 179), High averages 137 FPS, and Ultra averages 111 FPS. Again, only Medium has the full min/max data.

These numbers show that the Medium preset at each resolution has the most complete dataset, but the average FPS values are consistent across the board. The gap between the best and worst preset is largest at 1080p (60 FPS difference from Low to Ultra) and smallest at 4K (22 FPS difference), reinforcing the GPU-bound nature at higher resolutions.

FAQ

Q: What is the highest playable setting at 4K?

Q: Can this combo run the game at Ultra preset on a 2560x1440 monitor?

A: Yes. The Ultra preset at 2560x1440 averages 74 FPS, which is above the 60 FPS playable threshold.

Q: Which component is more limiting at 1080p?

A: The frame drop from Medium (155 FPS) to High (137 FPS) and then to Ultra (111 FPS) is significant, and the CPU has ample headroom. The data suggests the GPU is the primary bottleneck at 1080p.

Q: What is the minimum FPS recorded for the Medium preset at 1080p?

A: The database records a minimum of 132 FPS for the Medium preset at 1920x1080.

Q: How many frames per second does the Ultra preset achieve at 4K?

A: The Ultra preset at 3840x2160 averages 42 FPS, which is well below the 60 FPS threshold.

Q: Is the Arc B390 weaker than the GeForce GT 710?

A: No. The Intel Arc B390 scores 1482 in the database, while the NVIDIA GeForce GT 710 scores 1443. The Arc B390 is 2.7% faster in this metric.

How This Combo Ranks

The database ranks this combination at 3289 out of 3711 tested combos for Roblox. That places it in the lower percentile of all tested systems. The ranking suggests that while the CPU is capable (73rd percentile), the GPU is a serious limitation (9th percentile). Over half of the tested combos perform better. The frame data confirms this: the GPU holds back the system at 4K, and even at 1080p, the Ultra preset only reaches 111 FPS, which is far from the top of the spectrum. The i5-12400F is a strong processor, but the Arc B390 is the weakest link in this pairing, and the overall rank reflects that imbalance.
