Roblox

The Intel Core i5-13400F paired with the Intel Arc B570 delivers playable frame rates in Roblox across every resolution and preset tested. The combo averages 65 FPS at 4K Ultra, 114 FPS at 1440p Ultra, and 171 FPS at 1080p Ultra, all above the 60 FPS playability threshold. The combination ranks 2972nd out of 3711 tested combos for this game, placing it in the lower portion of the database despite strong individual component benchmark scores.

How This Combo Ranks

The combo’s overall rank in Roblox is 2972 out of 3711 tested combinations. That means roughly 80% of tested systems produce higher frame rates in this title, with only 739 combos ranking below it. The individual components, however, sit higher in their respective percentile rankings: the Core i5-13400F is in the 77th percentile of all CPUs, and the Arc B570 is in the 65th percentile of all GPUs. The gap between component percentiles and the low combo rank suggests that Roblox’s performance is sensitive to the specific pairing, not just raw component scores.

The CPU’s average benchmark score is 25292. Its nearest rivals in the database are extremely close: the AMD Ryzen 9 6900HS scores 25284 (0% delta), the Intel Core 5 120 scores 25362 (0.3% slower than the i5-13400F), the AMD Ryzen 5 5600X3D scores 25365 (0.3% slower), and the AMD Ryzen 7 6800H scores 25201 (0.4% faster than the i5-13400F). In practical terms, the i5-13400F is effectively tied with all four of these processors, with no single rival more than 0.4% ahead or behind.

The GPU’s average benchmark score is 20556. Its nearest rivals are similarly clustered: the NVIDIA GeForce RTX 3070 Mobile scores 20534 (0.1% slower than the Arc B570), the Intel Arc A750 scores 20582 (0.1% faster), the NVIDIA Quadro M4000M scores 20480 (0.4% slower), and the AMD Radeon R9 M390X scores 20662 (0.5% faster). The Arc B570 sits within a 0.5% band of all four rivals, making it a mid-pack performer in raw GPU benchmarks.

The low combo rank is not a reflection of weak individual parts. Rather, it shows that many other CPU/GPU pairings in the database achieve higher Roblox-specific frame rates, even though the i5-13400F and Arc B570 each hold their own against direct competitors.

CPU and GPU Roles

The measured frame rates show a clear pattern: FPS drops steadily as resolution increases, which points to the GPU becoming the dominant performance limiter at higher resolutions. At Low settings, the average FPS goes from 262 at 1080p to 175 at 1440p and 99 at 4K. That is a 33% drop from 1080p to 1440p, and a 43% drop from 1440p to 4K. At Ultra settings, the same trend appears: 171 FPS at 1080p, 114 FPS at 1440p, and 65 FPS at 4K, with drops of 33% and 43% respectively.

The consistency of these resolution-based drops indicates that the GPU is the primary constraint when moving to higher pixel counts. If the CPU were the main bottleneck, frame rates would remain relatively flat across resolutions, since the same CPU work would be required regardless of output resolution. The data shows the opposite: every doubling of pixel count from 1080p to 4K roughly halves the frame rate, which is characteristic of GPU-bound performance.

The impact of graphics presets is also consistent across resolutions. At 1080p, Low averages 262 FPS and Ultra averages 171 FPS, a 35% reduction. At 1440p, Low averages 175 FPS and Ultra averages 114 FPS, also a 35% reduction. At 4K, Low averages 99 FPS and Ultra averages 65 FPS, a 34% reduction. This uniform preset scaling suggests that the GPU is handling the extra shading and texture work at every resolution, while the CPU maintains enough headroom to keep feeding it.

At 1080p, the CPU’s role is more prominent because the GPU is less stressed. The i5-13400F’s 10 cores, 16 threads, and 4.60 GHz boost clock provide substantial processing power, and the 262 FPS result at 1080p Low shows no obvious CPU cap. At 4K, however, the GPU is clearly the limiting factor: even at Low settings the average is only 99 FPS, while at Ultra it falls to 65 FPS. The CPU has more than enough single-thread and multi-thread performance for Roblox, but the Arc B570’s workload scales heavily with both resolution and preset level.

The Verdict

This PC can run Roblox at all tested resolutions and presets. The verdict by resolution lists every setting — Low, Medium, High, and Ultra — as playable at 3840x2160, 2560x1440, and 1920x1080. The best settings preset at each resolution is Ultra, with average FPS of 65 at 4K, 114 at 1440p, and 171 at 1080p.

The 4K Ultra result is the closest to the 60 FPS threshold, but it still clears it. At 1440p and 1080p, there is substantial headroom, with Ultra averaging nearly double the threshold at 1440p and nearly triple at 1080p. For players targeting 60 FPS, this combo delivers at every resolution and every preset tested.

The Medium preset is the only one with reported min/max values. At 4K Medium, the minimum is 77 FPS, which is still well above 60. At 1440p Medium, the minimum is 135 FPS, and at 1080p Medium, the minimum is 203 FPS. These minimums confirm that even the lowest dips in the Medium preset stay far above the playability threshold.

Best Settings per Resolution

The most demanding preset that stays at or above 60 FPS is Ultra at every resolution. This is the highest preset tested, and it clears the threshold with room to spare in all three cases.

• 1920x1080: Ultra — 171 FPS average
• 2560x1440: Ultra — 114 FPS average
• 3840x2160: Ultra — 65 FPS average

At 1080p and 1440p, the Ultra preset provides a high-refresh-rate experience, with averages well above 100 FPS. At 4K, Ultra still maintains 65 FPS, making it a viable choice for players who prioritize visual quality over maximum frame rate. Since even the heaviest preset remains playable, there is no need to drop to lower settings to hit 60 FPS.
