Su AMD and Tim Apple are in different markets
Where Tim Apple sells easy to use smartphones to lefties Su AMD sells kick arse processors to computer builders from corporates to basement dwelling techies.
The techies have mostly replaced their i5 systems with RYZEN 5 systems. The latest RYZEN are superb but not so much better than the original that you need to upgrade.
The lefties continue to put their smartphones in their back pockets and then sit on them, thereby keeping Tim Apple happy.
The reason I say Apple users are lefties is because right wing content does not show up reliably on an iPhone. The Telegram App for instance is censored and you can use Apple for Cryptocurrency. OK so there are ways round these problems but you don't have these problems on a PC.
