Intel had accidentally posted a new graphics driver (18.104.22.16899) that references four of its upcoming “Arctic Sound” discrete GPUs. The code names suggest that three could be high-performance (HP) parts, while one could be lower ended (LP).
The leaked driver also reveals the graphics configurations for Intel’s 14 nm Rocket Lake chips, which are slated for release in mid-2020. These will utilize both 10 nm and 14 nm graphics chiplets.
We’re not entirely sure what the numbers at the end of the codenames mean at this time. If we had to make an educated guess, the numbers could represent the number of execution units (EUs) for each product. In that case, the DG2 family would have up to three members with 128, 256 and 512 EUs each. Judging by the number of EUs, the DG2 products are probably aimed at the mid-range segment.
