Worthless. One is efficient and did not launch an over-powered processor but a super-efficient one, the other launched a power-hungry but does more performance than the competition. Just go Intel if you don't care about power and wanted RTX 3080Tis. I hope AMD gets RTX 3080Ti laptops.

AMD's GPU is sooo much ahead of Intel's i9. More than double the speed.
