Previously known as DG1, Intel's Xe discrete GPUs may first launch with select Tiger Lake laptops. One of these could be the Asus VivoBook Flip 14 TP470EZ convertible that is advertised to be featuring the first Xe dGPU named Iris Xe Max. No official specs for this model as of yet besides the 4 GB GDDR5 VRAM, but we are hearing that it may feature a 96 EU G7 chip with higher clocks.
