FAQ

Q: Can this system run Roblox at 4K Ultra settings?

A: Yes. The measured average frame rate at 3840x2160 with Ultra settings is 65 FPS, which clears the 60 FPS playable threshold. The minimum frame rate at this setting was not recorded, but the average indicates consistent usability.

Q: What is the highest average frame rate recorded at 1080p?

A: The highest average at 1920x1080 is 262 FPS, achieved with Low settings. Medium settings produce 239 FPS, High produces 211 FPS, and Ultra produces 171 FPS. All comfortably exceed the 60 FPS threshold.

Q: How does the CPU compare to its closest rivals?

A: The Intel Core i5-9400's average benchmark score of 2254 is within 0.4 percent of all four nearest rivals. The Intel Core i3-10305 is the fastest at 2264, while the AMD Ryzen 5 PRO 1500 is the slowest at 2246. This means swapping to any of these CPUs would yield nearly indistinguishable performance in Roblox.

Q: Is the GPU or CPU more important for reaching high frame rates?

A: The data shows the GPU is the primary driver. At 1920x1080, dropping from Ultra to Low increases the average from 171 to 262 FPS, a 91 FPS gain. At 3840x2160, the same settings change yields only a 34 FPS gain (65 to 99 FPS). This resolution-dependent scaling indicates the GPU dominates at lower resolutions, while the CPU becomes relatively more relevant at higher resolutions.

Q: What is the minimum recorded frame rate across all tests?

A: The lowest minimum frame rate recorded is 77 FPS, occurring at 3840x2160 with Medium settings. The other two minimums are 135 FPS at 2560x1440 Medium and 203 FPS at 1920x1080 Medium. No minimum dips below the 60 FPS threshold.

Q: How does this system rank among all tested combinations?

A: This specific CPU and GPU pairing ranks 2972 out of 3711 tested combinations, placing it in the lower 20 percent of all possible configurations. However, this ranking reflects the full spectrum of hardware, not Roblox-specific performance, where this system clearly excels.

CPU and GPU Roles

The division of labor between the Intel Core i5-9400 and Intel Arc B570 becomes clear when examining frame rate scaling across resolutions and presets. At 1920x1080, the GPU is the dominant factor. Moving from Low to Ultra settings increases the rendering load substantially, and the average frame rate drops from 262 to 171 FPS, a 35 percent reduction. This steep decline indicates the GPU is working near its capacity at higher presets, while the CPU has ample headroom to feed frames at this resolution.

At 2560x1440, the pattern shifts. Low settings produce 175 FPS, while Ultra produces 114 FPS, a 35 percent reduction from the Low baseline. The absolute numbers are lower than at 1080p, but the proportional drop is similar. This suggests the GPU remains the bottleneck, but the CPU's contribution is becoming more noticeable as the resolution increases.

At 3840x2160, the balance changes again. Low settings yield 99 FPS, while Ultra yields 65 FPS, a 34 percent reduction. The absolute frame rates are significantly lower across all presets, indicating the GPU is now the primary constraint. The CPU's six cores and six threads, while sufficient, cannot compensate for the increased pixel throughput demanded at 4K. The measured data shows that the gap between Low and Ultra narrows slightly in percentage terms at higher resolutions, but the absolute frame rate drops more steeply, confirming the GPU's growing importance.

The preset scaling also reveals the CPU's role. At 1080p Low, the system reaches 262 FPS, which is near the practical limit for many display refresh rates. This high ceiling suggests the CPU can sustain very high frame rates when the GPU is not overloaded. At 4K Ultra, the 65 FPS average indicates the CPU is not the limiting factor; the GPU is struggling to keep pace with the pixel count. The verdict data confirms this: all four settings at all three resolutions are playable, meaning the CPU never becomes a hard bottleneck below 60 FPS.

The Verdict

This system can run Roblox with complete success across all tested configurations. The verdict by resolution shows that every setting at every resolution clears the 60 FPS playable threshold. At 1920x1080, the best playable setting is Ultra with an average of 171 FPS. At 2560x1440, Ultra also achieves the top spot with 114 FPS. At 3840x2160, Ultra remains playable at 65 FPS, and it is the best setting as well. The lowest average frame rate recorded anywhere is 65 FPS at 4K Ultra, which still exceeds the 60 FPS requirement by a comfortable margin. Users can enable maximum graphical fidelity at any resolution without worrying about playability. The system's performance headroom is substantial: even the most demanding preset at the highest resolution leaves 5 FPS of buffer above the threshold, and at lower resolutions the buffer grows to over 100 FPS.

Measured FPS Breakdown

At 1920x1080, the recorded data shows exceptional performance across all presets. Low settings deliver an average of 262 FPS, with no minimum or maximum recorded. Medium settings produce 239 FPS on average, with a minimum of 203 FPS and a maximum of 275 FPS. High settings drop to 211 FPS average, while Ultra settings maintain 171 FPS average. The minimum values, where recorded, never approach the 60 FPS threshold.

At 2560x1440, the system continues to perform strongly. Low settings achieve 175 FPS average, Medium settings reach 159 FPS with a minimum of 135 FPS and a maximum of 183 FPS, High settings yield 141 FPS, and Ultra settings produce 114 FPS. The minimum frame rate at Medium is 135 FPS, which is more than double the playable threshold.

At 3840x2160, performance remains solid but the margins tighten. Low settings average 99 FPS, Medium settings average 90 FPS with a minimum of 77 FPS and a maximum of 104 FPS, High settings average 80 FPS, and Ultra settings average 65 FPS. The minimum recorded at 4K is 77 FPS at Medium, which still leaves a 17 FPS buffer above the 60 FPS playable line. The data shows a consistent progression: as resolution increases, the average frame rates decline across all presets, but the system never falls below playable.

How This Combo Ranks

The Intel Core i5-9400 paired with the Intel Arc B570 ranks 2972 out of 3711 tested combinations in Roblox. This places the system in the bottom 20 percent of all possible hardware pairings in the database. However, this ranking must be interpreted with caution. The database includes combinations ranging from entry-level integrated graphics to flagship multi-thousand-dollar components. A rank of 2972 indicates that many more powerful systems exist, but the actual Roblox performance data tells a different story: this system achieves playable frame rates at every resolution and preset combination tested. The ranking reflects the hardware's position in the overall distribution, not its suitability for this specific game. In fact, the measured FPS data shows that even the weakest configuration (4K Ultra at 65 FPS) exceeds the playable threshold by 5 FPS, meaning the system is effectively overqualified for Roblox's demands.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 171 FPS. This leaves 111 FPS of headroom above the threshold, indicating the system could potentially handle even more demanding workloads.

At 2560x1440, Ultra is again the best setting, achieving 114 FPS average. This provides 54 FPS of buffer above the 60 FPS line, which is still a comfortable margin for competitive gameplay or high refresh rate displays.

At 3840x2160, Ultra remains the top choice, with an average of 65 FPS. This is the tightest margin in the dataset, but it still clears the 60 FPS requirement by 5 FPS. Players who prefer a larger safety margin could drop to High settings at 80 FPS, but the data confirms that Ultra is playable at 4K.

The recommendation across all resolutions is unambiguous: enable Ultra settings. The system's performance headroom at 1080p and 1440p is so large that reducing settings provides no practical benefit, and at 4K the Ultra preset still meets the playability standard. The data indicates that this hardware combination is well-matched to Roblox's requirements, delivering high frame rates even at maximum graphical fidelity.
