Roblox

Measured FPS Breakdown

At 3840x2160, the Intel Core i3-12100F and Intel Arc B390 combination delivers 52 FPS average on High settings, 64 FPS average on Low settings, 59 FPS average on Medium settings with a minimum of 50 FPS and a maximum of 67 FPS, and 42 FPS average on Ultra settings. The 4K results show a clear pattern: only the Low preset crosses the 60 FPS playability threshold, while Medium falls just one frame short at 59 FPS. The spread from Low to Ultra is 22 FPS, indicating that the GPU is the limiting factor at this resolution, as each step up in quality costs a noticeable chunk of performance.

Moving to 2560x1440, the numbers improve substantially. High settings produce 92 FPS average, Low settings reach 114 FPS average, Medium settings hit 104 FPS average with a minimum of 88 FPS and a maximum of 119 FPS, and Ultra settings deliver 74 FPS average. This resolution shows a much healthier performance envelope, with all four presets comfortably above the 60 FPS threshold. The gap between the fastest preset (Low at 114 FPS) and the slowest (Ultra at 74 FPS) is 40 FPS, which suggests that visual quality settings have a meaningful impact on frame rates even at 1440p.

At 1920x1080, this combination really stretches its legs. High settings average 137 FPS, Low settings average 171 FPS, Medium settings average 155 FPS with a minimum of 132 FPS and a maximum of 179 FPS, and Ultra settings average 111 FPS. The 1080p results are uniformly strong, with every preset delivering well above the 60 FPS playability threshold. Even the most demanding Ultra preset maintains a 111 FPS average, which leaves plenty of headroom for competitive play or high-refresh-rate displays. The minimum recorded frame rate across all 1080p presets is 132 FPS (on Medium), indicating excellent frame pacing with no dips below the playability threshold.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Low, which produces an average of 64 FPS. Medium falls just short at 59 FPS, so if you have a 4K display, you will need to run the game on Low to maintain smooth gameplay. The data does not show any 4K preset above Low that reaches 60 FPS, so this is the only viable option at this resolution.

At 2560x1440, every preset is playable, and the best choice is Ultra, which delivers 74 FPS average. This gives you the full visual experience while still maintaining a comfortable margin above the 60 FPS threshold. If you prefer higher frame rates, Medium offers 104 FPS and Low offers 114 FPS, but the Ultra preset is the highest quality option that stays playable.

At 1920x1080, the best settings are also Ultra, with an average of 111 FPS. This is the most demanding preset available, and it still delivers nearly double the playability threshold. For esports-style play, Low at 171 FPS or Medium at 155 FPS would be preferable, but Ultra is the top choice for visual fidelity without sacrificing smoothness.

CPU and GPU Roles

The data shows a clear division of labor between the CPU and GPU across resolutions. At 3840x2160, the performance drop from Low (64 FPS) to Ultra (42 FPS) is 22 FPS, a 34% reduction. This steep decline indicates that the Intel Arc B390, which ranks in the 9th percentile of all GPUs, is the primary bottleneck at 4K. The GPU's 3DMark Steel Nomad DX12 score of 1482 places it near very old discrete GPUs, so it simply lacks the raw throughput for high-quality 4K rendering.

At 2560x1440, the scaling pattern changes. The difference between Low (114 FPS) and Ultra (74 FPS) is 40 FPS, a 35% reduction, which is similar proportionally to 4K. However, the absolute frame rates are much higher, suggesting that the GPU is still the main constraint but has enough headroom at this resolution to keep all presets playable. The CPU, with its 4 cores and 8 threads and a 68th percentile ranking among all CPUs, is likely providing adequate single-thread performance (Cinebench R23 single-core score of 1674) without becoming a limiting factor.

At 1920x1080, the CPU becomes more relevant. The frame rates range from 111 FPS (Ultra) to 171 FPS (Low), a 60 FPS spread. This larger gap indicates that at lower resolutions, the GPU is less stressed and the CPU's performance ceiling starts to matter. The Core i3-12100F's strong single-thread results (Geekbench single-core score of 1932, PassMark single-thread score of 3444) help push frame rates higher at 1080p, but the GPU still dictates the scaling between presets. The fact that Ultra at 1080p (111 FPS) is faster than Low at 1440p (114 FPS) suggests that resolution scaling has a larger impact than preset scaling, which is typical for a GPU-bound scenario.

Similar Performance Alternatives

Looking at the CPU's nearest rivals, the Intel Core 3 N355 has an average benchmark score of 13492, which is 0% different from the Core i3-12100F's 13494. This means the N355 would deliver nearly identical CPU-bound performance in Roblox. The Intel Core i5-9500 scores 13452, a 0.3% difference, making it another close match. The Intel Core 5 120UL scores 13594, which is 0.7% higher, and the Intel Core i7-1250U scores 13351, which is 1.1% lower. All four alternatives fall within a narrow band of roughly 1.1% performance difference, so any of these CPUs would behave similarly in terms of frame delivery.

For the GPU, the closest rival is the NVIDIA GeForce GT 520MX with an average score of 1463, a 1.3% difference from the Arc B390's 1482. The NVIDIA GeForce 800M scores 1460, a 1.5% difference, and the NVIDIA GeForce GT 625 OEM scores 1446, a 2.5% difference. The NVIDIA GeForce GT 710 scores 1443, a 2.7% difference. These are all very old, low-end GPUs, so the Arc B390's performance class is clear. Users coming from any of these GPUs would see similar Roblox frame rates, though the Arc B390 has a slight edge over each of them.

FAQ

Q: Can this combination run Roblox at 4K?

A: Yes, but only on Low settings, which delivers 64 FPS average. Medium settings produce 59 FPS, just below the 60 FPS playability threshold, while High and Ultra drop to 52 FPS and 42 FPS respectively.

Q: What is the best settings preset at 1440p?

A: Ultra settings at 2560x1440 produce 74 FPS average, making it both the highest quality option and a playable one. All four presets at this resolution exceed 60 FPS, so you have full freedom to choose based on preference.

Q: Is the CPU or GPU more important for this game?

A: The GPU is the primary constraint at higher resolutions. The Arc B390 ranks in the 9th percentile of all GPUs, and the frame rate drops by 34% from Low to Ultra at 4K and by 35% at 1440p. At 1080p, the CPU's strong single-thread performance (Cinebench R23 single-core score of 1674) helps push frame rates higher, but the GPU still governs preset scaling.

Q: How does this combo compare to other tested combos?

A: This combination ranks 3289 out of 3711 tested combos for Roblox, placing it in the lower portion of the database. The rank reflects the GPU's low percentile standing, even though the CPU is above average.

Q: What frame rates can I expect at 1080p on High settings?

A: High settings at 1920x1080 deliver 137 FPS average. This is well above the 60 FPS threshold and provides smooth gameplay. For higher frame rates, Low settings reach 171 FPS, while Ultra still maintains 111 FPS.

Q: Are there any settings where this combo struggles?

A: At 3840x2160 on Ultra, the average FPS drops to 42, which is below the playability threshold. High at 4K also falls short at 52 FPS. At 1440p and 1080p, all settings remain playable, so the only problematic scenario is 4K with high or ultra quality presets.

How This Combo Ranks

The Intel Core i3-12100F and Intel Arc B390 combination ranks 3289 out of 3711 tested combos for Roblox, placing it in the 89th percentile of the database, meaning it sits below most other configurations. This low ranking is driven almost entirely by the GPU: the Arc B390's 3DMark Steel Nomad DX12 score of 1482 puts it in the 9th percentile of all GPUs, alongside ancient discrete cards like the GeForce GT 710 and GT 520MX. The CPU, in contrast, is a solid mid-range performer at the 68th percentile of all CPUs, with an average benchmark score of 13494.

The practical implication is that this combo is playable at 1080p and 1440p across all presets, and even at 4K on Low settings. However, the ranking reflects that most other tested combinations deliver higher frame rates, particularly at higher resolutions and quality settings. For a game like Roblox, which is not particularly demanding, this combo can still provide a smooth experience at mainstream resolutions, but the GPU's low percentile position means it will struggle to compete with even modest discrete graphics cards. The CPU has enough headroom to handle the game's physics and logic, but the Arc B390's performance class limits the overall result to the lower end of the database.
