Measured FPS Breakdown

At 3840x2160, the Intel Core i5-13400F paired with the Intel Arc B390 delivers a measured average of 52 FPS on High settings. The Low preset at this resolution pushes the average to 64 FPS, while Medium lands at 59 FPS with a minimum of 50 FPS and a maximum of 67 FPS. Ultra is the most demanding option here, producing an average of 42 FPS. The data shows a clear drop-off as settings climb, with a 22 FPS gap between Low and Ultra averages at 4K.

Moving to 2560x1440, the same hardware combination shows substantially stronger results. Low settings produce an average of 114 FPS, Medium follows at 104 FPS with a minimum of 88 FPS and a maximum of 119 FPS, High reaches 92 FPS, and Ultra still maintains an average of 74 FPS. The spread from Low to Ultra is 40 FPS, which indicates that the GPU handles the resolution well even at maximum quality presets.

At 1920x1080, the system performs best overall. Low settings yield an average of 171 FPS, Medium delivers 155 FPS with a minimum of 132 FPS and a maximum of 179 FPS, High produces 137 FPS, and Ultra remains playable at 111 FPS. The difference between Low and Ultra here is 60 FPS, showing that even the heaviest preset at 1080p leaves significant headroom above the 60 FPS playability threshold. The recorded data does not include minimum or maximum values for the Low, High, or Ultra presets at 1080p, but the averages alone indicate a smooth experience across the board.

When comparing resolutions, the scaling is consistent. At 4K, only the Low preset crosses the 60 FPS line, and even then it barely does so at 64 FPS. At 1440p, every preset clears 60 FPS, with Ultra sitting at 74 FPS and Low at 114 FPS. At 1080p, all presets exceed 100 FPS, with Ultra at 111 FPS and Low at 171 FPS. The performance drop from 1080p to 1440p is roughly 33 percent for Low settings, from 171 to 114 FPS, and about 33 percent for Ultra, from 111 to 74 FPS. The drop from 1440p to 4K is steeper: Low falls from 114 to 64 FPS, a 44 percent reduction, and Ultra falls from 74 to 42 FPS, a 43 percent reduction.

The Medium preset provides the only complete FPS profile across all resolutions. At 4K, the minimum of 50 FPS and maximum of 67 FPS show that the average of 59 FPS sits near the lower bound, meaning frame times are not entirely consistent. At 1440p, the Medium minimum of 88 FPS and maximum of 119 FPS bracket an average of 104 FPS, indicating a tighter distribution. At 1080p, Medium ranges from 132 to 179 FPS around a 155 FPS average, which is a wider relative spread but still well above the playability threshold.

CPU and GPU Roles

The benchmark results indicate that the Intel Arc B390 is the primary constraint at higher resolutions. The GPU's measured performance profile, with a 3DMark Steel Nomad DX12 score of 1482 and a percentile ranking of 9 among all GPUs, places it in the lower tier of graphics hardware. Its nearest rivals include the NVIDIA GeForce GT 520MX with a score of 1463 and a delta of 1.3 percent, the NVIDIA GeForce 800M at 1460 and a delta of 1.5 percent, the NVIDIA GeForce GT 625 OEM at 1446 and a delta of 2.5 percent, and the NVIDIA GeForce GT 710 at 1443 and a delta of 2.7 percent. These comparisons show that the Arc B390 sits just above these older, low-end parts in raw graphics compute.

At 4K, the GPU's limits become apparent. The difference between Low and Ultra averages is only 22 FPS, from 64 to 42, which suggests that the render pipeline is saturated regardless of settings. The CPU, by contrast, has substantial headroom. The Intel Core i5-13400F scores 25292 on average in CPU benchmarks, ranking in the 77th percentile among all CPUs. Its nearest rivals include the AMD Ryzen 9 6900HS at 25284 with a delta of 0 percent, the Intel Core 5 120 at 25362 with a delta of -0.3 percent, the AMD Ryzen 5 5600X3D at 25365 with a delta of -0.3 percent, and the AMD Ryzen 7 6800H at 25201 with a delta of 0.4 percent. This CPU has 10 cores, 16 threads, and a boost clock of 4.60 GHz, making it far more capable than the GPU in relative terms.

At 1440p, the GPU still dominates the performance picture. The fact that Low averages 114 FPS while Ultra averages 74 FPS shows that the GPU's shading units, 1536 in total, are the bottleneck when settings increase. The CPU's single-thread score of 960 in 3DMark and 3634 in PassMark single-thread tests is more than adequate for Roblox's typical load, which is not heavily threaded. The 10-core, 16-thread configuration with a 20 MB shared L3 cache provides plenty of parallel capacity for any background tasks, but the game itself likely uses only a few threads.

At 1080p, the balance shifts slightly. The GPU still matters, as evidenced by the 60 FPS gap between Low and Ultra, but the CPU's role becomes more visible. The 171 FPS average on Low settings approaches the practical ceiling for the GPU's pixel output at this resolution. The Arc B390's pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s set hard limits on how many frames can be rendered per second, regardless of CPU speed. The CPU's high single-thread performance, with a Cinebench R23 single-core score of 3191, ensures that it does not become the limiting factor even at high frame rates.

The scaling between resolutions confirms this division of labor. Going from 1080p to 1440p reduces Low FPS by 33 percent, from 171 to 114, which matches the increase in pixel count from roughly 2.07 million to 3.69 million, a 78 percent increase. The fact that FPS does not drop proportionally with pixel count suggests that some other limit, likely the CPU or memory bandwidth, is partially binding at 1080p. Going from 1440p to 4K reduces Low FPS by 44 percent, from 114 to 64, while pixel count increases by 125 percent. The GPU's fill rate and shader throughput become the dominant constraints at 4K, where the system can only manage 64 FPS on the least demanding preset.

Similar Performance Alternatives

Based on the nearest rivals in the database, the Intel Core i5-13400F performs nearly identically to several other processors. The AMD Ryzen 9 6900HS matches the i5-13400F with an average score of 25284 and a delta of 0 percent. The Intel Core 5 120 scores 25362, which is 0.3 percent higher, and the AMD Ryzen 5 5600X3D also scores 25365, also 0.3 percent higher. The AMD Ryzen 7 6800H trails slightly at 25201, a 0.4 percent difference. In practical terms, any of these CPUs would deliver virtually the same frame rates in Roblox, meaning the choice between them would come down to platform features rather than gaming performance.

The Intel Arc B390 has a much more limited set of comparable parts. Its 3DMark Steel Nomad DX12 score of 1482 places it just ahead of the NVIDIA GeForce GT 520MX at 1463, a 1.3 percent lead, and the NVIDIA GeForce 800M at 1460, a 1.5 percent lead. The NVIDIA GeForce GT 625 OEM scores 1446, which is 2.5 percent lower, and the NVIDIA GeForce GT 710 scores 1443, which is 2.7 percent lower. These are all very old, low-end discrete GPUs, so the Arc B390's performance class is clear: it is a budget-level graphics solution, not a mid-range or high-end part.

For a system using this CPU and GPU combination, the database indicates that swapping the CPU for any of its nearest rivals would not change Roblox performance in any meaningful way. The GPU is the limiting factor at all resolutions, so the CPU's 0.3 to 0.4 percent differences in synthetic benchmarks would translate to negligible FPS changes in-game. Conversely, upgrading the GPU to a part with a higher Steel Nomad score would yield immediate improvements, but the database does not list any such alternatives for the Arc B390 beyond the four low-end rivals mentioned.

The CPU's broader benchmark suite shows a well-rounded part. Its PassMark multithread score of 25032, Cinebench R23 multicore score of 22604, and Geekbench multicore score of 11068 all indicate strong productivity performance. The single-thread scores, including 3634 in PassMark and 3191 in Cinebench R23, are competitive for its generation. These figures matter because Roblox can be sensitive to single-thread performance in complex scenes, but the data shows that the CPU is not the bottleneck in this pairing.

The GPU's only benchmark entry is the 3DMark Steel Nomad DX12 score, which offers a narrow view of its capabilities. The architecture, Xe3-LPG on a 3 nm process, supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so it is modern in API support. However, the hardware specifications are modest: 1536 shading units, 48 texture mapping units, 24 ROPs, and 12 ray tracing cores. The FP32 compute of 7.680 TFLOPS and FP16 of 15.36 TFLOPS place it in the entry-level category. Any of the four rival GPUs listed would behave similarly, which means users upgrading from a GT 710 or GT 520MX would see a modest improvement, not a transformative one.

The Verdict

The recorded data shows that this PC can run Roblox, but the experience depends heavily on resolution and settings. At 1920x1080, every preset clears the 60 FPS playability threshold. The Ultra preset averages 111 FPS, High averages 137 FPS, Medium averages 155 FPS, and Low averages 171 FPS. This resolution is fully playable with no compromises needed.

At 2560x1440, the system also clears 60 FPS on all presets. Ultra averages 74 FPS, High averages 92 FPS, Medium averages 104 FPS, and Low averages 114 FPS. The minimum recorded frame rate at Medium is 88 FPS, which remains well above the threshold. This resolution is playable even at maximum quality, though the margin at Ultra is moderate.

At 3840x2160, the situation changes. Only the Low preset averages above 60 FPS, at 64 FPS. Medium averages 59 FPS, which is just below the threshold, and it has a minimum of 50 FPS, meaning frame drops are likely. High averages 52 FPS, and Ultra averages 42 FPS. For a consistent 60 FPS experience at 4K, users must select the Low preset, and even then, the margin is slim at 4 FPS above the threshold.

The verdict by resolution is clear: 1080p and 1440p are fully playable at all settings, while 4K requires Low settings to stay at or above 60 FPS. The system's combo rank of 3289 out of 3711 tested combinations in Roblox indicates that most other hardware configurations in the database perform better, but that does not negate the fact that this setup meets the playability threshold at two of three resolutions.

Best Settings per Resolution

At 3840x2160, the best settings that stay at or above 60 FPS are Low, with an average of 64 FPS. The Medium preset averages 59 FPS, which fails the 60 FPS requirement, so it cannot be recommended for this resolution. Low is the only option that clears the bar.

At 2560x1440, the best settings are Ultra, with an average of 74 FPS. This is the most demanding preset, and it still maintains a comfortable margin above the threshold. Users who prefer higher frame rates can choose Medium for 104 FPS or Low for 114 FPS, but Ultra is the optimal choice for visual quality without sacrificing playability.

At 1920x1080, the best settings are also Ultra, with an average of 111 FPS. All presets clear 60 FPS here, so there is no reason to reduce quality. The Ultra preset offers the highest visual fidelity while still delivering nearly double the playability threshold.
