Intel has detailed some of the features of its new Iris Xe Max DG1 discrete GPU solution for Tiger Lake laptops. Xe Max works together with the Xe iGPU in Tiger Lake processors to offer accelerated AI and media encode performance for creative workflows. While it does not work in an SLI-esque mode for gaming, Intel says Xe Max does offer great 1080p gaming performance that rivals an NVIDIA GeForce MX350 for thin and light gaming notebooks.
