How This Combo Ranks

The composite ranking for this specific CPU-GPU combination in Roblox is 2661 out of 3010 tested combinations. This places the system in the 11th percentile of all tested combos, indicating that most other pairings in the database will outperform it in this specific game. This low ranking is almost entirely attributable to the graphics processor's performance tier.

The Intel Arc B390 is the limiting factor. As an integrated GPU, its performance is at the lower end of the spectrum. Its average benchmark score of 1482 puts it in the 9th percentile of all GPUs. The nearest rivals are all older, entry-level discrete graphics cards. It is 1.3% faster than the NVIDIA GeForce GT 520MX, 1.5% faster than the NVIDIA GeForce 800M, and 2.7% faster than the NVIDIA GeForce GT 625 OEM and 2.7% faster than the NVIDIA GeForce GT 710.

In contrast, the CPU is a top-tier performer. The Ryzen 7 5800X3D has an average benchmark score of 27896, placing it in the 80th percentile of all CPUs. Its nearest rivals include the Intel Core i9-10900K, which it matches with a 0.1% delta, and the AMD Ryzen 7 6800U, which it exactly ties with at a 0% delta. This massive disparity in CPU and GPU performance classes explains the combo's overall ranking; the system is heavily held back by its graphics solution.

GPU Role

The Intel Arc B390 is the decisive component in this pairing, and its specifications and benchmark data clearly define its role. It is an integrated graphics processor (IGP) based on the Xe3-LPG architecture and built on Intel's 3 nm process node. Its performance is firmly in the entry-level category, as confirmed by its 9th percentile ranking among all GPUs.

The GPU's clock speeds are notable, with a base clock of 300 MHz and a boost clock of 2500 MHz. This boost clock is a key factor in the performance it does deliver, allowing it to reach a peak throughput of 7.680 TFLOPS for FP32 operations. However, the most significant limitation is its memory configuration. The Arc B390 uses "System Shared" memory, meaning it relies on the system's main RAM rather than dedicated VRAM. The bandwidth is listed as "System Dependent," which means performance is directly tied to the speed and architecture of the host system's memory.

This shared memory architecture explains the performance scaling observed in the measured FPS data. In a game like Roblox, which is not heavily GPU-bound at lower settings, the Arc B390 manages respectable frame rates. However, the system is likely constrained by memory bandwidth, which is why higher resolutions and more demanding presets cause a significant drop in performance. The data shows that while it can handle 1080p with ease, it begins to struggle at 1440p and 4K, where the need for faster memory access increases dramatically. The GPU's capabilities are sufficient for the game's demands, but its shared-memory design is a clear bottleneck for higher-fidelity settings.

Settings Recommendations

Based on the measured FPS data, the Medium settings preset offers the most balanced experience for this hardware combination across all tested resolutions. It provides a substantial visual improvement over the Low preset while maintaining average frame rates that are significantly higher than High or Ultra.

At 1920x1080, the Medium preset yields an average of 155 FPS. This is 16 FPS faster than High (137 FPS) and 44 FPS faster than Ultra (111 FPS), while still being only 16 FPS slower than Low (171 FPS). The frame time consistency is also good, with a minimum of 132 FPS and a maximum of 179 FPS. This makes it an excellent choice for high-refresh-rate monitors.

At 2560x1440, the Medium preset's advantage becomes clearer. It delivers an average of 104 FPS, which is a full 30 FPS more than the High preset (92 FPS) and 30 FPS more than Ultra (74 FPS). The minimum FPS is 88, ensuring a consistently smooth experience. This is the only preset at this resolution that comfortably exceeds the 100 FPS mark.

At 3840x2160, the Medium preset is the only one that approaches a playable 60 FPS average. It hits 59 FPS, with a minimum of 50 FPS and a maximum of 67 FPS. The Low preset is the only other option that breaks 60 FPS, at 64 FPS, but it sacrifices visual quality. The High and Ultra presets drop to 52 FPS and 42 FPS respectively, which are not ideal for a smooth experience.

For users targeting 1080p or 1440p, Medium is the optimal choice. For 4K gaming, users will have to choose between the slightly higher average frame rate of Low (64 FPS) or the better visuals of Medium (59 FPS), depending on their preference for smoothness versus fidelity.

Measured FPS Breakdown

The measured FPS data provides a clear picture of how this system scales across different resolutions and settings in Roblox.

1920x1080:

• Low: The highest average frame rate recorded at 171 FPS.
• Medium: A strong average of 155 FPS, with a range of 132 to 179 FPS.
• High: Delivers a solid 137 FPS average.
• Ultra: The most demanding preset at this resolution, producing an average of 111 FPS.

2560x1440:

• Low: The best performer here, achieving an average of 114 FPS.
• Medium: A very good average of 104 FPS, with a range of 88 to 119 FPS.
• High: Drops to an average of 92 FPS.
• Ultra: The largest performance hit, with an average of 74 FPS.

3840x2160:

• Low: The only preset to hit 64 FPS on average.
• Medium: Just misses the 60 FPS mark with an average of 59 FPS, ranging from 50 to 67 FPS.
• High: The average falls to 52 FPS.
• Ultra: The most demanding configuration, yielding an average of 42 FPS.

The data reveals a clear pattern. The performance drop from 1080p to 1440p is significant, and the drop from 1440p to 4K is even more pronounced. The system is most comfortable at 1080p, where it can max out all settings well above 100 FPS. At 1440p, it remains playable on all presets, but the Ultra preset dips to 74 FPS. At 4K, the system is only suitable for Low or Medium settings if a 60 FPS average is the target.

CPU Role

The AMD Ryzen 7 5800X3D plays a supporting role in this combo, ensuring that the system never becomes CPU-bound in Roblox. Its specifications and benchmark scores indicate that it has more than enough processing power to feed the Intel Arc B390.

The CPU is an 8-core, 16-thread processor based on the Zen 3 architecture (Vermeer). It has a base clock of 3.40 GHz and a boost clock of 4.50 GHz. A key feature is its large 96 MB shared L3 cache, which is designed to reduce memory latency and improve gaming performance. Its benchmark results reflect its strength. It scores 14317 in Cinebench R23 multi-core and 1452 in single-core. It also achieves 11765 in Geekbench multi-core and 2017 in single-core. These scores place it in the 80th percentile of all CPUs, showing it is a high-end processor.

In the context of this game, the CPU's role is to maintain a high minimum frame rate and ensure smooth frame pacing. The measured data shows that the average FPS drops significantly as resolution increases, which is a classic sign of a GPU bottleneck. The CPU is capable of far higher frame rates than the GPU can render, as evidenced by the 171 FPS average at 1080p Low. If the CPU were the limiting factor, the frame rates would be more consistent across different resolutions.

The Ryzen 7 5800X3D's robust performance means that the user can enable higher graphics settings without worrying about a CPU-induced stutter. The bottleneck is always the Arc B390's integrated graphics. The CPU's performance headroom is so large that it is effectively idle in this scenario, making the GPU's capabilities the sole determinant of the final frame rate. This pairing demonstrates a case where a top-tier CPU is completely held back by an entry-level GPU.
