Performance comparison: which is faster?
Intel Arc B580 (Intel, 2024) and Intel Arc A770 16GB (Intel, 2022) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: Arc B580 is about 10% faster
For generative AI, the higher-VRAM Arc A770 16GB（16GB） 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 B580 | Arc A770 16GB |
|---|---|---|
| Performance Score | 16,500 | 15,000 |
| VRAM | 12GB | 16GB |
| Manufacturer | Intel | Intel |
| Series | Arc B | Arc |
| Release Year | 2024 | 2022 |
| Compatible CPU Example | Ryzen 7 2700 | Ryzen 7 1800X |
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 A770 16GB also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | Arc B580 |
| Run larger generative AI and LLM models | Arc A770 16GB |
| Prioritize value and adequate performance | Arc A770 16GB (the lower model is often sufficient) |
Arc B580 is about 10% higher by score (Arc B580: 16500 points / Arc A770 16GB: 15000 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 B580 has 12GB of VRAM, while Arc A770 16GB has 16GB; Arc A770 16GB 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 2700 pairs well with Arc B580 and Ryzen 7 1800X with Arc A770 16GB (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
