CPU bottleneck check, compatible CPUs, and AI models it can run
Intel Arc A380 6GB / Intel made / Arc / Released 2022 Also known as: ArcA380 / A380
Intel Arc A380 6GB (Intel, released in 2022, also listed as ArcA380 / A380) is a graphics card with a performance score of 5,500 and 6GB of VRAM, TDP 75W. If CPU compatibility and performance balance are poor, a CPU bottleneck occurs, preventing Arc A380 6GB from reaching its full potential. In our estimate, the CPUs that pair best with Arc A380 6GB are Intel: Core i7-870 (estimated bottleneck: about 0%), and AMD: AMD FX-4300 (about 0%). Below are the top 10 compatible CPUs, CPUs to avoid, and generative AI models supported by this amount of VRAM.
CPUs are ordered by proximity to the ideal CPU:GPU ratio of 0.9:1. A lower bottleneck percentage means more of the GPU’s performance can be used.
The Bottleneck Checker opens with Intel Arc A380 6GB already selected.
Arc A380 6GB (ArcA380 / A380) has a performance score of 5,500 points. Using the same CPU:GPU ≈ 0.9:1 standard as the checker, compatibility by CPU score is shown below.
| Example CPUs to Pair | Rating | What It Means |
|---|---|---|
| AMD A10-7890K、Core i5-4460、AMD Phenom II X6 1055T | Great Match: 10% or Less | Optimal balance. Nearly all of Arc A380 6GB performance can be used |
| Core i3-4130、AMD Phenom II X4 955、Core i5-750 | Acceptable: 10–25% | Practical with no major issue. Consider a future upgrade if targeting high fps. |
| AMD Athlon II X4 645、Core i3-3220、Core i5-670 | CPU Too Weak: Over 25% | A clear CPU bottleneck. Much of the GPU performance is wasted |
| Ryzen 3 1300X、Core i5-5675C、Core i5-4690 | CPU Overkill | Likely overkill for gaming |
Note: Perceived results vary by resolution and game (GPU matters more at 4K, while CPU matters more at high-fps Full HD). For an exact estimate, use the Bottleneck Checker.
Runs Comfortably: Meets recommended VRAM / Barely Runs: Meets minimum VRAM (lower quality or quantization may be needed)

In our estimate, the best-balanced options are Core i7-870 for Intel (estimated bottleneck: about 0%) and AMD FX-4300 for AMD (about 0%). A CPU-to-GPU performance ratio near 0.9:1 tends to use both parts effectively. See the top 10 compatible CPUs in the table on this page.
As a guide, CPUs such as AMD Athlon II X4 645、Core i3-3220、Core i5-670、Core 2 Quad Q9650 push the bottleneck above 25% and waste much of the Intel Arc A380 6GB performance. On the other hand, CPUs such as Ryzen 3 1300X、Core i5-5675C、Core i5-4690 are likely overkill for gaming.
Intel Arc A380 6GB has 6GB of VRAM. It can comfortably run about 33 models, including Stable Diffusion and LLMs (for example, SD 1.5 (Q4 quantized), Stable Diffusion 1.5, SDXL (Q4 quantized)).
Intel Arc A380 6GB has a power draw (TDP) of 75W. At 75W or less, many models can operate without a PCIe auxiliary power connector, making them suitable for PCs with limited power-supply headroom. Check the actual CPU pairing balance in the bottleneck diagnosis above.
Its performance score is 5,500 points. CPU balance matters for gaming, while VRAM (6GB) matters for generative AI. Use the top 10 CPU list and AI model list above to check your use case.
