Roblox

Measured FPS Breakdown

Starting with the highest resolution, 3840x2160 (4K), the recorded data shows a narrow window of playability. At Low settings, the combo averages 64 FPS, which clears the 60 FPS threshold. Medium settings drop the average to 59 FPS, with a recorded minimum of 50 FPS and a maximum of 67 FPS, placing it just below the target. High settings average 52 FPS, and Ultra settings fall further to 42 FPS. The gap between Low and Ultra at 4K is 22 FPS, indicating that the graphics load heavily impacts performance at this resolution.

At 2560x1440, the picture improves significantly. Low settings deliver 114 FPS average, Medium produces 104 FPS (with a minimum of 88 FPS and a maximum of 119 FPS), High reaches 92 FPS, and Ultra still holds at 74 FPS. All four presets stay above 60 FPS, and even the most demanding preset maintains a comfortable margin. The spread from Low to Ultra is 40 FPS, showing that the GPU has more headroom at this resolution.

At 1920x1080, the combo is clearly at its strongest. Low settings reach 171 FPS average, Medium hits 155 FPS (minimum 132 FPS, maximum 179 FPS), High comes in at 137 FPS, and Ultra still produces 111 FPS. Every preset at 1080p is well above the 60 FPS line, with Ultra being 51 FPS above the threshold. The difference between Low and Ultra is 60 FPS, demonstrating that even the heaviest settings leave ample performance on the table.

The data pattern shows a consistent scaling: moving from 1080p to 1440p reduces FPS by roughly 30 to 40 percent depending on the preset, and moving from 1440p to 4K reduces it by another 40 to 50 percent. Minimum and maximum values are only recorded for the Medium preset at each resolution, which limits direct comparison, but the available values show a reasonable spread, suggesting stable frame pacing rather than erratic spikes.

Similar Performance Alternatives

The CPU, an Intel Core i5-14400F, holds the 83rd percentile among all CPUs in the database. Its nearest rivals in average benchmark score include the AMD Ryzen 7 PRO 8840U, which scores 0.1 percent higher, and the Intel Core i9-11900, which scores 0.2 percent higher. The AMD Ryzen 7 6800HS scores 0.2 percent lower, and the Intel Core i7-12800H scores 0.5 percent lower. These deltas are all within half a percent, meaning any of these CPUs would produce nearly identical results in Roblox, assuming the same GPU is paired with them.

The GPU, an Intel Arc B390, sits at the 9th percentile among all GPUs, which is considerably lower. Its nearest rivals are the NVIDIA GeForce GT 520MX (1.3 percent higher), NVIDIA GeForce 800M (1.5 percent higher), NVIDIA GeForce GT 625 OEM (2.5 percent higher), and NVIDIA GeForce GT 710 (2.7 percent higher). All of these GPUs are within roughly three percent of the Arc B390's 3DMark Steel Nomad DX12 score, so a system with any of them would behave similarly in Roblox, likely hitting the same FPS ranges at each resolution and preset.

For a user seeking comparable performance, swapping the i5-14400F for any of the four rival CPUs would not change the outcome meaningfully, as the delta is at most 0.5 percent. Swapping the Arc B390 for any of its rival GPUs would also be a near wash, though the GT 710 and GT 625 OEM are slightly faster, and the GT 520MX and 800M are slightly slower. The overall combo ranking of 3289 out of 3711 combinations reflects the GPU's low percentile, so similar combos would likely rank in the same neighborhood, driven primarily by the graphics card's modest compute capabilities.

The Verdict

The data is clear: this PC can run Roblox, but with important caveats at the highest resolution. At 1920x1080, the verdict is unambiguous. Every preset, from Low to Ultra, stays above 60 FPS. Ultra averages 111 FPS, which is 51 FPS above the playable threshold. At 2560x1440, the verdict is equally positive. Ultra averages 74 FPS, and all lower presets also clear the line. At 3840x2160, only Low settings are playable, with a 64 FPS average. Medium falls 1 FPS short at 59 FPS, High is 8 FPS short at 52 FPS, and Ultra is 18 FPS short at 42 FPS.

The database's verdict by resolution confirms this: 4K lists Low as the only playable setting, while 1440p and 1080p list all four presets as playable. For a 60 FPS target, users should stick to 1080p or 1440p for unrestricted settings, or drop to Low at 4K. The system is clearly capable of running the game smoothly, but 4K Ultra is not within reach.

CPU and GPU Roles

The benchmark data reveals how the balance shifts across resolutions. At 1080p, the CPU likely has more influence, as the FPS numbers are high enough that the GPU is not fully saturated. The difference between Low (171 FPS) and Ultra (111 FPS) is 60 FPS, which suggests the GPU still matters, but the CPU's single-thread performance, measured at 3055 in Cinebench R23 single-core and 3701 in PassMark single-thread, is sufficient to feed the GPU.

At 1440p, the GPU's role grows. The spread between Low (114 FPS) and Ultra (74 FPS) is 40 FPS, a smaller absolute gap than at 1080p but with lower overall FPS. This indicates the GPU is becoming the limiting factor, as raising settings reduces FPS more proportionally. At 4K, the GPU dominates. The spread from Low (64 FPS) to Ultra (42 FPS) is 22 FPS, and the average FPS is much lower across all presets, meaning the GPU's compute capacity, rated at 7.680 TFLOPS FP32, is the primary constraint.

The CPU's multi-thread capabilities, with a Cinebench R23 multi-core score of 21645 and a PassMark multithread score of 25470, are far above what Roblox likely needs. The GPU's 3DMark Steel Nomad score of 1482, however, places it in the 9th percentile, so it is the weaker link. The scaling between resolutions confirms this: going from 1080p to 1440p reduces FPS by roughly 30 to 40 percent, and going from 1440p to 4K reduces it by another 40 to 50 percent. That scaling is characteristic of a GPU-bound scenario, where the CPU is waiting on the graphics card.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Low, with an average of 64 FPS. Medium is 1 FPS short at 59 FPS, so it is not recommended for a strict 60 FPS target. At 2560x1440, the best preset is Ultra, averaging 74 FPS. This is 14 FPS above the threshold, so there is no need to compromise on visual quality. At 1920x1080, the best preset is also Ultra, averaging 111 FPS. This is 51 FPS above the threshold, leaving substantial headroom for any background tasks or future game updates that might add load.

For users who prefer maximum visual fidelity, 1440p Ultra is the sweet spot, offering 74 FPS. For those who want the highest frame rates, 1080p Low at 171 FPS is the fastest option, though even 1080p Ultra at 111 FPS is far above the playable line. At 4K, the choice is limited to Low, and the 64 FPS average is just 4 FPS above the threshold, so any additional load could push it under.

How This Combo Ranks

The combination of the Intel Core i5-14400F and Intel Arc B390 ranks 3289 out of 3711 tested combos in Roblox. This places it in the lower 11 percent of all combinations, which is consistent with the GPU's low percentile ranking of 9. The CPU, at the 83rd percentile, is not the bottleneck, but the GPU's modest performance drags the overall ranking down.

To put this in context, the CPU alone is in the top 17 percent of all CPUs, while the GPU is in the bottom 9 percent. The combo rank of 3289 reflects a strong CPU paired with a weak GPU. In Roblox, which appears to be sensitive to graphics settings based on the FPS scaling, the GPU's limitations are the primary reason the combo does not rank higher. If the same CPU were paired with a more capable GPU, the combo rank would likely improve substantially, but with the Arc B390, the system sits near the lower end of the database's tested combinations. The data suggests that users with this combo should prioritize lower resolutions or reduced settings to achieve high frame rates, as the CPU has plenty of headroom but the GPU is the decisive factor.
