Intel driver reveals four Xe discrete GPUs

Intel accidentally published a developer version of its 26.20.16.9999 graphics driver that revealed a bit too much information about its future GPU lineup. The driver, which has since been taken down, contained references to four discrete Xe series GPUs as well as various upcoming processors like Lakefield, Elkhart Lake, Tiger Lake, Rocket Lake, and Alder Lake. TechSpot has all the details and some speculation over here:

The highlight, of course, is the references to Intel’s new Xe discrete GPUs, which are mentioned five times. Three mentions are thick with detail; “iDG2HP512,” “iDG2HP256,” and “iDG2HP128.” All Intel graphics processors feature the “i,” “DG” is thought to mean discrete graphics and the “2” is the variant. “HP” could mean high-power, implying these are fully-fledged desktop GPUs, and the following three-digit number could be the number of execution units, Intel’s equivalent to CUDA cores.

...

The last two mentions of discrete GPUs are vaguer. An “iDG1LPDEV” suggests that a “1” low-power variant is in the works and might arrive later, due to the “dev” status. It could be a separate GPU for laptops. An “iATSHPDEV” name references the Arctic Sound code-name, which Intel is using for its first-generation discrete GPUs. Code relating to it describes it as using Gen12 architecture in a high-power configuration. It might be initial testing of a second-gen component.

Intel expects to launch its discrete GPUs in 2020.
