Performance comparison: which is faster?
Intel Arc B570 (Intel, 2025) and Intel Arc A580 8GB (Intel, 2023) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: Arc B570 is about 38.1% faster
For generative AI, the higher-VRAM Arc B570（10GB） has the advantage. For gaming, prioritize performance score and CPU compatibility; for AI, prioritize VRAM.
Relative performance score (higher is faster). Actual fps varies by resolution, game, and CPU configuration.
| Item | Arc B570 | Arc A580 8GB |
|---|---|---|
| Performance Score | 14,500 | 10,500 |
| VRAM | 10GB | 8GB |
| Manufacturer | Intel | Intel |
| Series | Arc B | Arc |
| Release Year | 2025 | 2023 |
| Compatible CPU Example | Ryzen 7 1700X | Core i7-5775C |
These generative AI models can run on only one GPU because of the VRAM difference (Stable Diffusion, Flux, LLMs, and others).
— None (all models that run on Arc B570 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | Arc B570 |
| Run larger generative AI and LLM models | Arc B570 |
| Prioritize value and adequate performance | Arc A580 8GB (the lower model is often sufficient) |
Arc B570 is about 38.1% higher by score (Arc B570: 14500 points / Arc A580 8GB: 10500 points). Actual fps also varies by resolution, game, and CPU, so price is a reasonable deciding factor when the gap is only a few percent.
Arc B570 has 10GB of VRAM, while Arc A580 8GB has 8GB; Arc B570 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Ryzen 7 1700X pairs well with Arc B570 and Core i7-5775C with Arc A580 8GB (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
