Performance comparison: which is faster?
Intel Arc A310 4GB (Intel, 2023) and UHD Graphics 620 (Intel, 2017) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: Arc A310 4GB is about 359.8% faster
For generative AI, the higher-VRAM Arc A310 4GB（4GB） 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 A310 4GB | UHD Graphics 620 |
|---|---|---|
| Performance Score | 4,000 | 870 |
| VRAM | 4GB | Shared |
| Manufacturer | Intel | Intel |
| Series | Arc | Integrated |
| Release Year | 2023 | 2017 |
| Compatible CPU Example | AMD Phenom II X4 945 | Core 2 Quad Q6600 |
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 A310 4GB also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | Arc A310 4GB |
| Run larger generative AI and LLM models | Arc A310 4GB |
| Prioritize value and adequate performance | UHD Graphics 620 (the lower model is often sufficient) |
Arc A310 4GB is about 359.8% higher by score (Arc A310 4GB: 4000 points / UHD Graphics 620: 870 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 A310 4GB has 4GB of VRAM, while UHD Graphics 620 has Shared; Arc A310 4GB has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, AMD Phenom II X4 945 pairs well with Arc A310 4GB and Core 2 Quad Q6600 with UHD Graphics 620 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
