Roblox

Intel Core i5-9400 paired with Intel Arc B370 delivers a highly variable experience in Roblox, heavily dependent on resolution. At 1920x1080, the combination is exceptionally strong, with all tested presets comfortably exceeding the 60 FPS threshold. The data shows a clear trend: as resolution climbs to 2560x1440, performance remains solid but begins to compress, while 3840x2160 pushes the system past its limits for smooth play.

Measured FPS Breakdown

At 1920x1080, the recorded data shows a robust performance envelope. The Low preset averages 154 FPS, which is the highest recorded for this combination. Medium settings produce an average of 140 FPS, with a minimum of 119 FPS and a maximum of 161 FPS, indicating a very stable experience. High settings average 124 FPS, while the demanding Ultra preset still manages an average of 101 FPS. Every setting at this resolution clears the 60 FPS playability bar with considerable headroom.

Moving to 2560x1440, the average frame rates step down noticeably but remain playable across the board. The Low preset averages 103 FPS. Medium settings deliver 94 FPS on average, with recorded minimums of 80 FPS and maximums of 108 FPS. High settings average 83 FPS, and Ultra drops to an average of 67 FPS. The gap between Low and Ultra shrinks at this resolution, going from a 53 FPS difference at 1080p to a 36 FPS difference at 1440p, showing that the system becomes more uniformly constrained.

At 3840x2160, none of the tested presets reach the 60 FPS average threshold. The Low preset comes closest with an average of 58 FPS. Medium settings average 53 FPS, with a minimum of 45 FPS and a maximum of 61 FPS, which shows occasional dips below comfortable playability. High settings average 47 FPS, while Ultra averages just 38 FPS. The data reveals a steep drop-off at 4K, where even the least demanding preset struggles to maintain a consistent 60 FPS.

How This Combo Ranks

In the database of tested combinations for Roblox, this pairing sits at rank 3417 out of 3711 combos. That places it in the lower percentile of all recorded systems, which is surprising given the strong 1080p results. The ranking suggests that while this combo handles Roblox adequately at lower resolutions, many other hardware pairings deliver higher overall performance in this specific title.

The rank reflects a system that is capable but not exceptional. The Intel Core i5-9400 scores in the 47th percentile among all CPUs, meaning it sits near the middle of the pack for general processing tasks. The Intel Arc B370, however, ranks in the 5th percentile among all GPUs, indicating that the graphics component is far less competitive relative to the broader hardware landscape. This imbalance helps explain why the combo ranks so low overall, despite producing playable frame rates at 1080p and 1440p. The data implies that the GPU is the limiting factor for this game, particularly as resolution demands increase.

FAQ

Q: How much performance is lost between 1080p and 1440p on Medium settings?

A: The average FPS drops from 140 at 1920x1080 to 94 at 2560x1440, a decrease of 46 FPS.

Q: What are the minimum and maximum FPS recorded at 3840x2160 on Medium?

A: The minimum is 45 FPS and the maximum is 61 FPS, showing significant frame time variability at 4K.

Similar Performance Alternatives

Looking at the nearest rivals for the Intel Core i5-9400, the database shows several CPUs with nearly identical average benchmark scores. The Intel Core i7-1068NG7 scores 2259, which is 0.2% higher. The Intel Core i3-10305 scores 2264, 0.4% higher. The Intel Core i7-10710U scores 2248, 0.3% lower, and the AMD Ryzen 5 PRO 1500 scores 2246, 0.4% lower. These processors would likely produce very similar CPU-bound performance in Roblox, meaning the frame rates would be nearly indistinguishable at the same resolution and settings.

On the GPU side, the Intel Arc B370 has an average 3DMark Steel Nomad score of 1184. Its nearest rivals include the ATI Mobility Radeon HD 5570 at 1186 (0.2% higher), the ATI Radeon HD 5770 at 1190 (0.5% higher), the AMD Radeon HD 7650M at 1192 (0.7% higher), and the AMD FirePro M2000 at 1168 (1.4% lower). These graphics solutions fall within a tight performance band, so swapping the Arc B370 for any of them would likely yield similar Roblox frame rates, with the FirePro M2000 being slightly weaker and the Radeon HD 7650M marginally stronger.

For users seeking similar overall behavior, pairing the i5-9400 with any of the listed rival GPUs would produce comparable results. The data suggests that the exact choice among these near-identical components matters little for Roblox, as the performance deltas are all under 1.5%.

CPU and GPU Roles

The benchmark data reveals a clear division of labor between the CPU and GPU for this game. At 1920x1080, the system shows strong scaling across presets, with the average FPS dropping from 154 on Low to 101 on Ultra. This 34% reduction indicates that the GPU is being increasingly taxed as visual fidelity rises. The CPU, with its 6 cores and 6 threads, appears sufficient to feed the GPU at this resolution, as even the most demanding preset maintains a high average.

At 2560x1440, the performance gap between presets narrows. Low averages 103 FPS while Ultra averages 67 FPS, a 35% reduction. The absolute numbers are lower across the board, but the proportional scaling is similar to 1080p. This suggests that both the CPU and GPU are being pushed harder, but the GPU is still the primary bottleneck. The 83 FPS average on High at 1440p versus the 124 FPS at 1080p shows a 33% drop, which aligns with the increased pixel count.

The picture changes dramatically at 3840x2160. Low averages 58 FPS, while Ultra averages just 38 FPS, a 34% reduction from Low to Ultra. However, the absolute performance is much lower, with even the least demanding preset failing to hit 60 FPS. The data implies that the GPU is severely overtaxed at 4K, as the rendering load grows exponentially with resolution. The CPU likely has headroom to spare, but the Arc B370 cannot keep up with the pixel throughput demands. The scaling between 1440p and 4K on Low settings (103 FPS to 58 FPS) represents a 44% drop, which is disproportionately large compared to the resolution increase, further confirming the GPU as the limiting factor at high resolutions.

The Verdict

This system can run Roblox, but the playable range depends entirely on the target resolution. At 1920x1080, every tested preset clears the 60 FPS threshold, making this an excellent setup for high-refresh-rate monitors. The Ultra preset averages 101 FPS, providing a fully smooth experience. At 2560x1440, all presets also clear 60 FPS, with Ultra averaging 67 FPS, which is playable but with less margin for complex scenes. At 3840x2160, no preset reaches the 60 FPS average, with Low falling just short at 58 FPS. The verdict by resolution is clear: 1080p and 1440p are fully playable at all settings, while 4K is not recommended for smooth gameplay.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 101 FPS. This allows users to enable maximum visual quality without sacrificing playability. At 2560x1440, Ultra also remains the best choice, averaging 67 FPS, which still clears the threshold by a reasonable margin. At 3840x2160, no preset achieves the required 60 FPS average, so the data does not recommend any setting for this resolution. Users targeting 4K would need to accept sub-60 FPS performance or lower the resolution to achieve smoother frame rates. For the best balance of visual fidelity and performance, the database points to Ultra at 1440p as the sweet spot, delivering strong visuals while maintaining a playable frame rate.
