Performance comparison: which is faster?
UHD Graphics 770 (Intel, 2021) and UHD Graphics 630 (Intel, 2017) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: UHD Graphics 770 is about 100% 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 | UHD Graphics 770 | UHD Graphics 630 |
|---|---|---|
| Performance Score | 2,000 | 1,000 |
| VRAM | Shared | Shared |
| Manufacturer | Intel | Intel |
| Series | Integrated | Integrated |
| Release Year | 2021 | 2017 |
| Compatible CPU Example | Core 2 Duo E6750 | Core 2 Quad Q6600 |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | UHD Graphics 770 |
| Run larger generative AI and LLM models | UHD Graphics 770 |
| Prioritize value and adequate performance | UHD Graphics 630 (the lower model is often sufficient) |
UHD Graphics 770 is about 100% higher by score (UHD Graphics 770: 2000 points / UHD Graphics 630: 1000 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 Duo E6750 pairs well with UHD Graphics 770 and Core 2 Quad Q6600 with UHD Graphics 630 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
