Performance comparison: which is faster?
Iris Xe Graphics G7 (Intel, 2022) 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: Iris Xe Graphics G7 is about 302.3% 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 | Iris Xe Graphics G7 | UHD Graphics 620 |
|---|---|---|
| Performance Score | 3,500 | 870 |
| VRAM | Shared | Shared |
| Manufacturer | Intel | Intel |
| Series | Integrated | Integrated |
| Release Year | 2022 | 2017 |
| Compatible CPU Example | AMD A6-7470K | Core 2 Quad Q6600 |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | Iris Xe Graphics G7 |
| Run larger generative AI and LLM models | Iris Xe Graphics G7 |
| Prioritize value and adequate performance | UHD Graphics 620 (the lower model is often sufficient) |
Iris Xe Graphics G7 is about 302.3% higher by score (Iris Xe Graphics G7: 3500 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, AMD A6-7470K pairs well with Iris Xe Graphics G7 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.
