Yep, wccftech interprets this now as DG1 is tigerlake's iGPU in a discrete form factor, with 96EUs.
It's more or less known for quite some time that DG1 is basically TGL GT2. A lot of people may have missed that DG1 is Gen12LP based and DG2 Gen12HP. DG1 never was going into the mainstream or higher because it uses the Gen12LP architecture. They still could reach 2 Tflop with 1.5 Ghz GPU clock which is comparable to an GTX 1050 Ti/GTX 1050 when it comes to raw power. I do hope Intel releases DG1 for the desktop and not only for mobile, I'm curious about the Quicksync and media capabilities of Gen12LP.
