Your computer always has been limited by the intentions of the system designer. It’s not malice, it’s market-fit and optimization.

Look at those x3d variants that amd has been putting out. Fantastic for gamers, but relatively niche for general computing tasks. If I were an OEM, would I pick those parts for my workstation prebuilts? Fuck no, they’re overpriced for someone using office and a web browser. But for my gaming line, maybe, if I could get a deal.

All computers have many of these price/performance/size/power draw/availability decisions to make, and portables even more so. Apple knows that most of their users need xyz, and they build for that. Everyone else’s needs go into the pile of lower priority, some of which will be supported if they feel like it.
