I don't think so. There are only 2 Rembrandt-U models and one of them has only 6CUs which is a joke. So there is only 1 model left who crushes Intel in the iGPU department.
In the overall scheme this is nothing. And by the way, Meteor Lake 2 years away, seriously? Meteor Lake is coming in H1 2023. You wil lose this bet easily.
1.5 year or two doesn't make a difference because it's a long time either way. And I don't know why you have such confidence when they never released mobile early for so long. Every year it's been late fall/early winter since the Haswell generation when the releases got delayed.
Raptorlake doesn't seem to do anything on the GPU department either so it's a solid 50%+ win from AMD for 1.5 years. Tell me you really think they'll just stay with one SKU?
Even Tigerlake's iGPU win has lots of fine prints and astericks. As long as you set it at 28W, as long as you have LPDDR4X, as long as it's not artifacting due to drivers.
You are also assuming AMD will do nothing when Meteorlake comes out. Yes, Phoenix is a small iGPU gain but what about after that?
