Intel Iris, that is, GT3 desktop!

Fourth-generation Intel Core processors have more powerful IGPs than ever before. The engineers have set up 3 categories: GT1 with 10 executive units, GT2 with double that, and GT3, which again offers twice as many processing units. Intel has installed an L4 eDRAM cache (Multi-Chip Modules) alongside the most powerful IGP, so its performance really outperforms the current generation.

The GT3 integrated graphics processor has been (partly) renamed Intel: the flagship is the Iris Pro 5200, followed by the Iris 5100 and finally the HD 5000. The common point is the 40 executive units, but there may be differences in clock speeds.

The “R” indicator also comes in color for easier identification - such as the Core i7-4770R. With this letter, Intel wants to present that the product has the strongest IGP.
