Performance comparison: which is faster?
Intel Arc A770 16GB (Intel, 2022) 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 A770 16GB is about 42.9% 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 A770 16GB | Arc A580 8GB |
|---|---|---|
| Performance Score | 15,000 | 10,500 |
| VRAM | 16GB | 8GB |
| Manufacturer | Intel | Intel |
| Series | Arc | Arc |
| Release Year | 2022 | 2023 |
| Compatible CPU Example | Ryzen 7 1800X | 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 A770 16GB also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | Arc A770 16GB |
| Run larger generative AI and LLM models | Arc A770 16GB |
| Prioritize value and adequate performance | Arc A580 8GB (the lower model is often sufficient) |
Arc A770 16GB is about 42.9% higher by score (Arc A770 16GB: 15000 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 A770 16GB has 16GB of VRAM, while Arc A580 8GB has 8GB; 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 1800X pairs well with Arc A770 16GB 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.
