Performance comparison: which is faster?
HD Graphics 630 (Intel, 2017) 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: HD Graphics 630 is about 9.2% faster
Both have Shared of VRAM, so they support a similar range of generative AI models. 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 | HD Graphics 630 | UHD Graphics 620 |
|---|---|---|
| Performance Score | 950 | 870 |
| VRAM | Shared | Shared |
| Manufacturer | Intel | Intel |
| Series | Integrated | Integrated |
| Release Year | 2017 | 2017 |
| Compatible CPU Example | Core 2 Quad Q6600 | Core 2 Quad Q6600 |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | HD Graphics 630 |
| Run larger generative AI and LLM models | HD Graphics 630 |
| Prioritize value and adequate performance | UHD Graphics 620 (the lower model is often sufficient) |
HD Graphics 630 is about 9.2% higher by score (HD Graphics 630: 950 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.
Both have Shared of VRAM, so the range of generative AI models they can run is nearly the same.
Using our guideline, Core 2 Quad Q6600 pairs well with HD Graphics 630 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.
