Why it's so hard for AMD to break through

It is the users that need help, not the OEMs. When you buy a desktop replacement laptop and some of thr usb ports dont work it isn't becsuse Intel didn't help The OEM it is because the OEM just doean't care.

It mostly works the other way. Intel mad a batxh of Xe 'graphics' cards that can't be put in front of consumers so Dell will fill a warehouse in Texas with them until they landfill them in Louisiana like the Atari E.T. cartridges.
