CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on the Raptor Lake architecture. It operates with a base clock of 2.50 GHz and can boost up to 4.60 GHz, which provides the responsiveness needed for Roblox's often physics-heavy and script-driven gameplay. The processor's substantial L3 cache of 20 MB (shared) is crucial for keeping game data readily accessible, reducing latency and ensuring smooth frame delivery.

Benchmark results confirm the CPU's strength. In Cinebench R23, it scores 22604 points in the multicore test and 3191 points in the single-core test, showing a balanced capability for both multi-threaded workloads and the single-threaded tasks that often dominate game logic. Its Passmark single-thread score of 3634 is particularly relevant for a game like Roblox, where a single core frequently handles the primary game simulation.

The CPU's performance relative to its rivals is remarkably tight. Its average benchmark score of 25292 is virtually identical to that of the AMD Ryzen 9 6900HS (25284), with a deltaPct of 0. It is also on par with the Intel Core 5 120 (25362) and the AMD Ryzen 5 5600X3D (25365), both of which are only 0.3% faster. This suggests that in CPU-bound scenarios, this processor is a highly consistent performer, delivering a predictable level of performance that is competitive with a range of popular alternatives.

Given the high frame rates observed at lower resolutions, the CPU is clearly capable of feeding the GPU with enough data to exceed 170 FPS in Roblox. The 16 threads provide ample headroom for background tasks and the game's various subsystems, ensuring that the processor does not become a bottleneck until frame rates reach very high levels. The data indicates a well-balanced platform where the CPU's capabilities are more than sufficient for the game's demands.

Settings Recommendations

For the best experience, the data points to the Medium preset at 2560x1440 as the optimal choice. This configuration delivers an average of 104 FPS with a minimum of 88 FPS and a maximum of 119 FPS, providing a smooth and responsive experience that stays comfortably above the 60 FPS threshold. The frame time consistency, implied by the min/max figures, is solid, making this the sweet spot for balancing visual quality and performance.

At 1920x1080, the Medium preset is also highly recommended, boasting an average of 155 FPS with a minimum of 132 FPS and a maximum of 179 FPS. This is an excellent option for gamers with high refresh rate monitors, as it provides a very fluid experience. The Low preset at 1080p reaches an even higher 171 FPS average, but the visual compromise is likely unnecessary given the Medium preset's strong performance.

The High and Ultra presets are viable but come with significant performance costs. At 1440p, High drops to 92 FPS, which is still playable, but Ultra falls to 74 FPS. At 4K, the High preset manages only 52 FPS, and Ultra drops to 42 FPS, which is below the ideal threshold for smooth gameplay. Therefore, for 4K gaming, the Low preset, with a 64 FPS average, is the only option that provides a consistently playable frame rate.

Ultimately, the measured data suggests that users should prioritize the Medium preset for the best overall experience. It offers a significant visual upgrade over Low while maintaining frame rates that are high enough for competitive play. The Ultra preset, while visually demanding, does not provide a proportional performance benefit, making it a less attractive option for this hardware configuration.

How This Combo Ranks

The configuration places 2661st out of 3010 tested combos in the Roblox benchmark database, positioning it in the lower 12th percentile of all systems tested. This ranking is a direct result of the Intel Arc B390's low performance tier. While the CPU is a solid mid-range performer, the GPU's 9th percentile ranking among all GPUs significantly drags down the overall combo's standing in the game.

The GPU's average benchmark score of 1482 is its primary weakness. This score is only slightly above that of the NVIDIA GeForce GT 520MX (1463), a product from a much older generation. The deltaPct values of 1.3%, 1.5%, 2.5%, and 2.7% against its nearest rivals show that it is only marginally faster than some of the weakest GPUs in the database, highlighting its entry-level positioning.

This ranking has practical implications. While the system can handle Roblox, it will not compete with high-end configurations that occupy the top ranks. The data indicates that the user will be limited to lower resolutions and settings to achieve high frame rates. The combo is functional but not competitive, and the ranking accurately reflects the hardware's overall performance capabilities in this specific title. It is a clear case where the CPU's strength cannot compensate for the GPU's limitations.

GPU Role

The Intel Arc B390 is an integrated GPU based on the Xe3-LPG architecture, built on a 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. Its performance is fundamentally constrained by its "System Shared" memory configuration, meaning it relies on system RAM instead of dedicated VRAM, with bandwidth that is "System Dependent" on the rest of the platform.

The GPU's benchmark data is stark. It has a single 3DMark Steel Nomad DX12 score of 1482, which places it in the 9th percentile of all GPUs. This is a very low score, and its nearest rivals are the NVIDIA GeForce GT 520MX (1463), GeForce 800M (1460), GT 625 OEM (1446), and GT 710 (1443). The fact that it is only a few percentage points faster than these legacy parts underscores its position as a very basic graphics solution.

In Roblox, the GPU's role becomes increasingly critical as resolution increases. At 1920x1080, the GPU is less stressed, allowing the CPU to push frame rates to 171 FPS on Low settings. However, the performance drops sharply with resolution. The difference between the 1080p and 4K results on High settings (137 FPS vs 52 FPS) shows that the GPU struggles with the increased pixel count, making it the primary bottleneck in higher resolution scenarios. Its 7.680 TFLOPS of FP32 compute power is simply not sufficient for demanding 4K workloads in this game.

Measured FPS Breakdown

The measured frame rate data reveals a consistent scaling pattern across resolutions and settings. At 1920x1080, the combo delivers its best results. The Low preset achieves an average of 171 FPS. The Medium preset averages 155 FPS, with a minimum of 132 FPS and a maximum of 179 FPS, showing a stable performance range. High settings drop to 137 FPS, while the Ultra preset brings the average down to 111 FPS.

Moving to 2560x1440, performance remains strong but shows a clear step down. The Low preset leads with an average of 114 FPS. Medium follows at 104 FPS, with a minimum of 88 FPS and a maximum of 119 FPS, still a very smooth experience. High settings average 92 FPS, and the Ultra preset falls to 74 FPS, which is the first point where the experience could start to feel less fluid for some users.

At 3840x2160, the GPU becomes the dominant limiting factor. The Low preset is the only setting that maintains a playable average, at 64 FPS. Medium follows at 59 FPS, with a minimum of 50 FPS and a maximum of 67 FPS. High settings drop to 52 FPS, and the Ultra preset yields an average of just 42 FPS. The data shows a clear trend: the system is ideal for 1080p, very good for 1440p, but only marginally playable at 4K, requiring the lowest settings for a consistent experience.
