GPU Role

The Intel Arc B390 is an integrated GPU based on the Xe3-LPG architecture and a 3 nm process node. Its role in this Roblox configuration is singular, as it is the only graphics processor available. The data shows it relies on System Shared memory, with the memory type, bus width, and bandwidth all listed as system-dependent. This means the GPU's performance is tied directly to the system's main memory and CPU.

The GPU's clock speeds are listed as a 300 MHz base and a 2500 MHz boost, which allows for a significant dynamic range depending on thermal and power headroom. In terms of raw specifications, it has 1536 shading units, 48 TMUs, and 24 ROPs. The data also shows 12 ray tracing cores and a DirectX 12 Ultimate (12_2) API support, which is a modern feature set. Its theoretical pixel rate is 60.00 GPixel/s, and its texture rate is 120.0 GTexel/s.

When looking at its performance, the Arc B390 has an average benchmark score of 1482, placing it in the 9th percentile of all GPUs. This low percentile is reflected in its closest rivals, which are older, entry-level dedicated GPUs like the NVIDIA GeForce GT 520MX and the GT 710, from which it leads by 1.3% and 2.7%, respectively. These figures suggest that while the Arc B390 has modern architecture, its integrated nature and shared memory configuration limit its absolute performance to a level comparable to very old, low-end discrete solutions. The 12 GB of VRAM is not a factor, as the memory size is listed as System Shared, meaning it draws from the main system memory rather than having its own dedicated pool.

How This Combo Ranks

The combination of the Intel Core i5-12400F and the Intel Arc B390 achieves a rank of 2661 out of 3010 tested combos in Roblox. This places the system in the lower 12% of the performance spectrum, a position that aligns with the GPU's low 9th percentile standing. The CPU, in contrast, performs much better relative to its peers, sitting in the 73rd percentile of all CPUs. This mismatch suggests that the GPU is the primary bottleneck in this pairing.

The fact that the combo ranks lower than the CPU's percentile might indicate that the CPU is capable of more, but the GPU cannot deliver the frames to take advantage of it. The data implies that the Arc B390 is the limiting factor. The CPU, with a strong multicore score of 12380 in Cinebench R23, is being held back by a GPU that performs on par with GPUs from over a decade ago. This rank is a direct consequence of the GPU's performance ceiling, which is evident in the measured FPS where even at 1080p Low, the system only manages to average 171 FPS, a number that, while smooth, is not exceptionally high for such a low-end preset.

Measured FPS Breakdown

The measured FPS data provides a clear picture of the system's capabilities across different resolutions and settings. At 1920x1080, the system shows a range of performance. With Low settings, the average FPS is 171. Moving to Medium, the average drops to 155 FPS, with a minimum of 132 and a maximum of 179. High settings yield an average of 137 FPS, and Ultra averages 111 FPS. This shows that at 1080p, the system can easily handle the game, maintaining high frame rates even on Ultra.

At 2560x1440, the performance scales down as expected. Low settings average 114 FPS, Medium averages 104 FPS with a min/max of 88 and 119, High averages 92 FPS, and Ultra averages 74 FPS. These numbers indicate a solid experience at 1440p, with even the Ultra preset staying comfortably above 60 FPS.

The 3840x2160 results show the system being pushed harder. The Low preset averages 64 FPS, which is still playable. Medium averages 59 FPS with a min of 50 and a max of 67. High settings average 52 FPS, and the Ultra preset drops to an average of 42 FPS. The data shows that at 4K, the system struggles to maintain a smooth 60 FPS on anything above the Low preset, and the Ultra preset's 42 FPS average would likely present noticeable stutter in a fast-paced game. The difference between the 1080p and 4K results highlights the GPU's limitations when the resolution demands more from it.

CPU Role

The Intel Core i5-12400F is a 6-core, 12-thread processor from Intel's Core 12th Gen series, based on the Alder Lake architecture. It has a base clock of 2.50 GHz and a boost clock of 4.40 GHz. The CPU's cache configuration includes an 80 KB L1 cache per core, a 1.25 MB L2 cache per core, and a shared 18 MB L3 cache. It supports both DDR4 and DDR5 memory across a dual-channel bus.

In synthetic benchmarks, the i5-12400F shows strong results. Its Cinebench R23 multi-core score is 12380, and its single-core score is 1680. The Geekbench multi-core score is 9472, and the single-core score is 1964. These scores place the CPU in the 73rd percentile of all CPUs, indicating it is a solid mid-range performer. Its nearest rivals, like the AMD Ryzen 5 7535HS, score nearly identically in average benchmarks, confirming its position.

For a game like Roblox, which can be sensitive to single-thread performance, the i5-12400F's single-core capabilities are more than adequate. The data suggests that the CPU is not the bottleneck in this system. The 3DMark scores for 2 threads (1699) and 4 threads (3067) are respectable, and the Passmark single-thread score of 3481 is strong. The CPU can clearly keep up with the demands of the game, as evidenced by the fact that the FPS drops are much more pronounced when resolution increases, pointing to the GPU as the limiting factor. The CPU has the headroom to feed the Arc B390, but the GPU cannot process the frames fast enough to fully utilize the CPU's potential.

Settings Recommendations

Based on the measured FPS data, the best experience depends on the user's resolution and preference for frame rate versus visual fidelity. At 1920x1080, the Ultra preset is a viable option, as it still averages 111 FPS, which is well above the 60 FPS target for smooth gameplay. For users who prioritize a higher refresh rate, the Low preset at 171 FPS would be preferable, but Ultra offers a significant visual upgrade for a moderate FPS cost.

At 2560x1440, the High preset appears to be the sweet spot. It averages 92 FPS, which is a good balance between visual quality and performance. The Ultra preset drops to 74 FPS, which is still playable, but the High preset offers a safer margin above the 60 FPS threshold. For those who want the highest frame rates, the Low preset at 114 FPS is an option, but Medium at 104 FPS provides a better visual experience with a minimal performance hit.

At 3840x2160, the data suggests that the Low preset is the most consistent choice for a smooth experience, with an average of 64 FPS. The Medium preset at 59 FPS is also a reasonable option, but it is just below the 60 FPS mark. The High and Ultra presets, with averages of 52 and 42 FPS, respectively, are likely to feel less fluid. Therefore, for 4K gaming, the Low preset is recommended to maintain a stable frame rate, as the visual difference between Low and Medium may not be worth the drop in performance. Overall, the data indicates that the system is best suited for 1080p and 1440p gaming, where it can handle higher settings with ease.

Resolution Scaling

The FPS data from 1080p to 4K reveals a clear scaling pattern that points to the GPU as the primary limiting component. At 1080p Low, the system averages 171 FPS. Moving to 1440p Low, the average drops to 114 FPS, a 33% decrease. At 4K Low, the average is 64 FPS, which is a 63% decrease from the 1080p result and a 44% decrease from the 1440p result.

This pattern is consistent across all settings. For example, with the Ultra preset, the 1080p average is 111 FPS. At 1440p, it drops 33% to 74 FPS. At 4K, it drops a further 43% to 42 FPS. The percentage drops are significant, indicating that the GPU's rendering capabilities are being saturated as the pixel count increases.

The fact that the FPS scales so heavily with resolution points to the GPU being the bottleneck. A CPU-limited scenario would show a flatter FPS curve across resolutions, as the CPU would be the limiting factor regardless of the number of pixels. Here, the FPS drops sharply as resolution increases, which is a classic sign of a GPU that is running out of fill rate or memory bandwidth. The Arc B390's reliance on System Shared memory is likely a major contributor to this, as the bandwidth is not dedicated and can become a constraint at higher resolutions. The data strongly suggests that while the i5-12400F has enough power to drive high frame rates, the Intel Arc B390 is simply not powerful enough to maintain those frame rates when the resolution demands more from it.
