Roblox

Measured FPS Breakdown

The recorded data for Roblox on this Intel Core i5-12600KF and Intel Arc B390 combination shows a clear progression from 4K to 1080p. At 3840x2160, the average frame rates are the lowest of the three tested resolutions. The Low preset averages 64 FPS, Medium averages 59 FPS with a minimum of 50 and maximum of 67, High averages 52 FPS, and Ultra drops to 42 FPS. These figures indicate that 4K is demanding for this hardware, as only the Low preset clears the 60 FPS threshold, while Medium falls just one frame short on average.

Moving to 2560x1440, the performance improves substantially. Low settings average 114 FPS, Medium averages 104 FPS with a minimum of 88 and maximum of 119, High averages 92 FPS, and Ultra averages 74 FPS. Every preset at this resolution exceeds the 60 FPS playable threshold, with even the most demanding setting holding a comfortable margin above the target. The gap between Low and Ultra here is 40 FPS, which shows that the visual settings have a significant impact on the frame rate at this resolution.

At 1920x1080, the combination delivers its best results. Low settings reach an average of 171 FPS, Medium averages 155 FPS with a minimum of 132 and maximum of 179, High averages 137 FPS, and Ultra averages 111 FPS. All presets at 1080p are far above the 60 FPS mark, and the minimum recorded frame time for the Medium preset still sits at 132 FPS, which is more than double the playable threshold. The scaling from 4K to 1080p is steep: the Ultra preset jumps from 42 FPS to 111 FPS, a 69 FPS increase, while the Low preset climbs from 64 FPS to 171 FPS.

The data also shows that the Medium preset is the only one with recorded minimum and maximum values across all resolutions. At 1080p Medium, the spread from minimum to maximum is 47 FPS, at 1440p Medium it is 31 FPS, and at 4K Medium it is 17 FPS. This suggests that frame pacing becomes more consistent as resolution decreases, which is typical for a system where the GPU is less stressed at lower pixel counts.

Q: What is the highest resolution where all presets are playable?

A: 2560x1440 is the highest resolution where every preset, from Low to Ultra, averages at or above 60 FPS. At 3840x2160, only the Low preset meets the threshold, while at 1920x1080 and 1440p, all presets are playable.

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. The Medium preset comes close at 59 FPS, but it does not meet the playable threshold, so Low is the only viable option for 4K.

For 2560x1440, the Ultra preset is the best choice, averaging 74 FPS. This is the highest visual quality available, and it still provides a comfortable margin above the 60 FPS target. Users who prefer higher frame rates can select High at 92 FPS, Medium at 104 FPS, or Low at 114 FPS, but Ultra offers the best balance of quality and performance.

At 1920x1080, the Ultra preset averages 111 FPS, making it the most demanding setting that remains playable. The lower presets, High at 137 FPS, Medium at 155 FPS, and Low at 171 FPS, all deliver even higher averages, but Ultra is the recommended setting for maximum visual fidelity without dropping below the threshold.

The Verdict

This PC combination can run Roblox, and the data shows that it does so comfortably at most resolutions. At 1920x1080, all presets clear the 60 FPS threshold by a wide margin, with Ultra averaging 111 FPS and Low reaching 171 FPS. At 2560x1440, every preset also stays above 60 FPS, with Ultra averaging 74 FPS, which means users can play at the highest settings without any performance concerns.

The situation changes at 3840x2160. The verdict data lists Low as the only playable setting, averaging 64 FPS. Medium falls to 59 FPS, High drops to 52 FPS, and Ultra bottoms out at 42 FPS. For 4K gaming, the user must accept reduced visual quality to maintain smooth gameplay. The overall picture is that this combo is well suited for 1080p and 1440p gaming, where it can handle maximum settings, but 4K requires compromises.

The playable threshold is defined as 60 FPS, and the recorded numbers show that the system exceeds this at 1440p and 1080p for all presets. At 4K, only the Low preset meets the requirement. The data suggests that the ideal experience is at 1440p with Ultra settings, which offers a high frame rate of 74 FPS while preserving visual detail.

CPU and GPU Roles

The interaction between the Intel Core i5-12600KF and the Intel Arc B390 becomes clear when examining the frame rate scaling across resolutions. The GPU, which has a benchmark score of 1482 and sits in the 9th percentile of all GPUs, appears to be the limiting factor at higher resolutions. At 4K, the average frame rates are significantly lower than at 1440p, with the Ultra preset dropping from 74 FPS to 42 FPS as resolution increases. This pattern indicates that the GPU is struggling to fill the larger pixel count.

The CPU, by contrast, is a much stronger component. It has an average benchmark score of 27799 and ranks in the 79th percentile of all CPUs. Its multi-threaded performance, as measured by Cinebench R23 at 23391, and single-thread performance at 3302, are robust. At 1080p, where the GPU has less work to do, the frame rates are very high, reaching 171 FPS on Low and 111 FPS on Ultra. This suggests that the CPU is not holding back the system at lower resolutions.

The scaling between presets reveals the GPU's role more precisely. At 1080p, moving from Low to Ultra reduces the average FPS from 171 to 111, a drop of 60 FPS. At 1440p, the same preset change reduces FPS from 114 to 74, a drop of 40 FPS. At 4K, the drop is from 64 to 42, a 22 FPS difference. The absolute impact of preset changes shrinks as resolution increases, which is consistent with a GPU that becomes more saturated at higher pixel counts.

At 4K, the GPU is almost certainly the bottleneck, as even the Low preset only manages 64 FPS, and the Ultra preset falls to 42 FPS. The CPU has plenty of headroom, given its strong benchmark scores, but the GPU cannot keep up with the demand. At 1080p and 1440p, the GPU is still the primary driver of performance differences between presets, but the CPU provides enough throughput to keep the frame rates high. The data indicates that for this game, the GPU matters more at 4K, while the CPU becomes less critical as resolution decreases.

How This Combo Ranks

The database places this Intel Core i5-12600KF and Intel Arc B390 combination at rank 3289 out of 3711 tested combos for Roblox. This puts it in the lower portion of the rankings, specifically in the 11th percentile of all tested systems. The low rank is largely attributable to the GPU, which itself ranks in the 9th percentile of all GPUs and has an average benchmark score of 1482. Its nearest rivals, the NVIDIA GeForce GT 520MX with a score of 1463 and a delta of 1.3%, the NVIDIA GeForce 800M at 1460 with a delta of 1.5%, the NVIDIA GeForce GT 625 OEM at 1446 with a delta of 2.5%, and the NVIDIA GeForce GT 710 at 1443 with a delta of 2.7%, are all older or lower-end parts.

The CPU, on the other hand, ranks much higher, in the 79th percentile of all CPUs. Its nearest rivals include the Intel Core i9-10900K with an average score of 27872 and a delta of -0.3%, the AMD Ryzen 7 6800U at 27887 with a delta of -0.3%, the AMD Ryzen 7 5800X3D at 27896 with a delta of -0.3%, and the AMD Ryzen 5 8500GE at 27712 with a delta of 0.3%. This shows that the CPU is competitive with high-end processors from previous generations, but the GPU drags the overall combo down.

Despite the low rank, the measured FPS in Roblox are playable at 1080p and 1440p, because the game is not particularly demanding on the GPU at those resolutions. The rank reflects the hardware's raw compute capabilities relative to other tested systems, not the actual gaming experience in this specific title. The data shows that a powerful CPU paired with a weak GPU can still deliver smooth frame rates in less demanding games, even if the combo ranks poorly overall. For users who prioritize 1440p gaming in Roblox, this combination is acceptable, but for more graphically intensive titles, the GPU would likely become a significant limitation.
