I don't think thats accurate, AMD had like ~62% mobile discrete while Nvidia lost down to ~38% in mobile discrete while the numbers where nearly the same for desktop discrete but with Nvidia getting the majority.

AMD actually performed very strong in mobile discrete against Nvidia but lost a chunk of mobile marketshare volume to Intel.

Nvidia took the biggest hit in the mobile sector really.
