Roblox

The Intel Core i5-10400F paired with the Intel Arc B390 presents a specific performance profile for Roblox, a sandbox title with a long history of updates. This analysis pulls directly from recorded benchmark data to break down how this combination handles different resolutions and quality presets. The data shows a clear pattern: the system is comfortably capable at 1080p and 1440p, but struggles to maintain smooth frame rates at 4K with higher settings. The following sections provide a detailed breakdown of the measured FPS, component roles, and practical recommendations based solely on the numbers in the database.

Measured FPS Breakdown

The database records average FPS for this combo at three resolutions (1920x1080, 2560x1440, 3840x2160) across four settings presets (Low, Medium, High, Ultra). Some entries include minimum and maximum FPS values, while others only list the average. All numbers below come directly from the recorded data.

At 1920x1080, the system delivers strong performance across the board. The Low preset hits an average of 171 FPS, the highest recorded for this combo. Medium averages 155 FPS, with a minimum of 132 FPS and a maximum of 179 FPS. High drops slightly to an average of 137 FPS. The most demanding preset, Ultra, still manages an average of 111 FPS. No minimum or maximum values are recorded for Low, High, or Ultra at this resolution, but the averages alone indicate that all presets clear the 60 FPS playable threshold by a wide margin.

At 2560x1440, performance remains strong but shows a noticeable step down. Low averages 114 FPS. Medium averages 104 FPS, with a minimum of 88 FPS and a maximum of 119 FPS. High averages 92 FPS. Ultra averages 74 FPS, which is still above the 60 FPS threshold. Again, only Medium has recorded min/max values, with the 88 FPS minimum being the lowest recorded frame rate at this resolution across any preset.

At 3840x2160, the picture changes significantly. Low averages 64 FPS, just clearing the playable threshold. Medium averages 59 FPS, with a minimum of 50 FPS and a maximum of 67 FPS. This is the only 4K preset with full min/max data, and the 50 FPS minimum shows that the system can dip below 60 FPS during demanding scenes. High averages 52 FPS, and Ultra averages 42 FPS. None of the 4K presets except Low reach an average of 60 FPS or higher. The gap between Low and Ultra at 4K is 22 FPS, from 64 down to 42.

Looking at the scaling from 1080p to 1440p, the average FPS drops roughly 33% to 35% across all presets. For example, High goes from 137 FPS at 1080p to 92 FPS at 1440p, a reduction of 45 FPS. From 1440p to 4K, the drop is even steeper. High goes from 92 FPS to 52 FPS, a reduction of 40 FPS. Medium goes from 104 FPS to 59 FPS, a reduction of 45 FPS. The data indicates that the system's performance degrades rapidly as pixel count increases, particularly beyond 1440p.

CPU and GPU Roles

The recorded data suggests that the GPU is the primary limiting factor at higher resolutions, while the CPU provides sufficient headroom at lower resolutions. The Intel Core i5-10400F is a 6-core, 12-thread processor with a boost clock of 4.30 GHz and a 12 MB shared L3 cache. Its benchmark scores, including a Cinebench R23 multicore score of 10283 and a single-core score of 1451, indicate a capable mid-range CPU. The Intel Arc B390, by contrast, has a much lower performance profile. Its only recorded benchmark is a 3DMark Steel Nomad DX12 score of 1482, and it ranks in the 9th percentile of all GPUs.

The FPS scaling between resolutions points directly to GPU saturation. At 1080p, the CPU can feed frames quickly enough to reach 171 FPS on Low, but the GPU still manages to deliver 111 FPS on Ultra. The difference between Low and Ultra at 1080p is 60 FPS, which shows that the GPU is not the bottleneck at this resolution; the CPU is likely the limit for the higher frame rates seen on Low. At 1440p, the gap between Low and Ultra narrows to 40 FPS (114 vs. 74), indicating that the GPU is starting to take on more load. At 4K, the gap between Low and Ultra is just 22 FPS (64 vs. 42), and neither reaches 60 FPS except Low. This compression of FPS across presets as resolution increases is a classic sign of GPU-bound behavior.

The CPU's role is more evident at 1080p, where the system can push well above 100 FPS even on Ultra. The i5-10400F's single-thread performance, reflected in a Geekbench single-core score of 1420 and a Passmark single-thread score of 2541, is sufficient to handle Roblox's physics and game logic at these frame rates. However, at 4K, the GPU's compute throughput becomes the limiting factor. The Arc B390's FP32 performance of 7.680 TFLOPS and its 24 ROPs are modest, and the data shows that it cannot maintain 60 FPS at 4K on Medium or higher. The GPU's memory bandwidth is listed as "System Dependent" and its memory type is "System Shared," which further suggests that at 4K, memory bandwidth constraints could be exacerbating the performance drop.

In summary, the CPU is not the bottleneck at any resolution tested. The GPU dictates the playable settings at 4K, while at 1080p and 1440p, the combination of CPU and GPU is sufficient for high frame rates. The steep FPS decline from 1440p to 4K (e.g., Medium drops from 104 to 59 FPS) confirms that the Arc B390 is the component that limits this combo at higher pixel counts.

Similar Performance Alternatives

The database provides nearest rival comparisons for both the CPU and GPU, based on average benchmark scores. These are not direct gaming comparisons but indicate which components would perform similarly in synthetic benchmarks.

For the Intel Core i5-10400F, the nearest rivals are:

• Intel Xeon 6756E, with an average score of 14163, which is 0.2% lower than the i5-10400F's 14185.
• Intel Core 7 160UL, with an average score of 14232, which is 0.3% higher.
• AMD EPYC 7552, with an average score of 14115, which is 0.5% lower.
• AMD Ryzen 3 7320C, with an average score of 14277, which is 0.6% higher.

These deltas are all within 1% of the i5-10400F's average benchmark score, meaning that swapping to any of these CPUs would likely result in nearly identical CPU-bound performance in Roblox. The EPYC 7552 and Xeon 6756E are server-class parts, but their benchmark similarity suggests they would handle the CPU load similarly for this game.

For the Intel Arc B390, the nearest rivals are:

• NVIDIA GeForce GT 520MX, with an average score of 1463, which is 1.3% higher.
• NVIDIA GeForce 800M, with an average score of 1460, which is 1.5% higher.
• NVIDIA GeForce GT 625 OEM, with an average score of 1446, which is 2.5% higher.
• NVIDIA GeForce GT 710, with an average score of 1443, which is 2.7% higher.

These are all older, low-end GPUs. The GT 710 and GT 520MX are entry-level cards from previous generations. The deltas range from 1.3% to 2.7%, which means the Arc B390's performance is closely matched by these GPUs in the 3DMark Steel Nomad test. In practical terms, a system with a GT 710 or GT 625 OEM would likely produce very similar FPS in Roblox at the same settings and resolutions, though the Arc B390 supports newer APIs like DirectX 12 Ultimate and Vulkan 1.4, which could affect compatibility in other titles. For Roblox, which is not graphically demanding, the FPS differences between these GPUs would be marginal, so the recorded data for this combo should be a reliable guide for what to expect from those alternatives.

Q: Does this combo rank high among all tested combinations?

A: No, it ranks 3289 out of 3711 combinations in the database, placing it in the lower portion of tested systems.

How This Combo Ranks

The database ranks this specific CPU and GPU combination at 3289 out of 3711 tested combos. This places it in the bottom 12% of all recorded systems. The ranking reflects the overall performance of the pair across all games, not just Roblox. Given that the Arc B390 sits in the 9th percentile of all GPUs and has a single benchmark score of 1482, the low rank is expected. The i5-10400F, by contrast, ranks in the 68th percentile of all CPUs, indicating that the GPU is dragging the combo down. For Roblox specifically, the ranking still holds relevance because the game's performance is heavily GPU-bound at higher resolutions, as shown by the FPS scaling. A better GPU would likely push this combo much higher in the rankings, but with the Arc B390, the overall system performance is limited.

Best Settings per Resolution

Based on the recorded data, the most demanding preset that stays at or above 60 FPS average is as follows:

At 1920x1080, all presets clear 60 FPS. The most demanding preset is Ultra, which averages 111 FPS. This is the recommended setting for 1080p.

At 2560x1440, all presets also clear 60 FPS. Ultra averages 74 FPS, making it the best choice. The minimum recorded FPS for Medium is 88, so Ultra likely stays above 60 for most of the session, though no minimum is recorded for Ultra.

At 3840x2160, only Low averages 64 FPS, which is above 60. Medium averages 59 FPS, just below the threshold, and its minimum is 50 FPS. Therefore, Low is the only acceptable preset for 4K if the goal is to stay at or above 60 FPS on average.

The data shows a clear progression: Ultra is viable at 1080p and 1440p, but at 4K, the user must drop to Low to maintain smooth gameplay.

The Verdict

Yes, this PC can run Roblox, but the playable experience depends heavily on resolution. At 1920x1080, the system clears 60 FPS on all presets, with Ultra averaging 111 FPS. At 2560x1440, Ultra averages 74 FPS, so the full quality range is available. At 3840x2160, only the Low preset averages 64 FPS, which is above the playable threshold, but Medium and higher all fall below 60 FPS. The verdict by resolution is clear: 1080p and 1440p are fully playable at maximum settings, while 4K requires a significant reduction to Low settings to avoid frame rate drops. The recorded minimum of 50 FPS at 4K Medium indicates that even the 59 FPS average includes dips below 60, so users should stick to Low at 4K for consistent performance. For anyone playing at 1080p or 1440p, this combo delivers a smooth experience with headroom for high refresh rates. At 4K, the Arc B390 becomes the limiting factor, and the system is not suitable for high-quality 4K gameplay.
