For now Zen 5 brings one really good thing: bringing down to earth people valuing theoretical "upgrade path" to the point it was no discussion for them between "dead platform" Intel and "futureproof" AM5. Especially I talk times when AM5 was pricier, giving you less performance and long before we heard about Intel's problems. Next generation may happen similar - not worth upgrading. Some of them are probably these naive guys who wouldn't believe such things to happen, because for them AMD are here these good guys... Like being a good guy has anything to technological advancement...
There're two things with upgrade path making it thing rather garbage:
- it needs to deliver chips, them being worth buying and it all when you need to upgrade. Less than more likely for them to meet.
- the only thing "upgrade path" guarantees is destroying resell values of your CPU and mobo by flooding market with compatible parts and newer being more attractive than yours. It's likely that it will lower value of your stuff by more than you would need to spend on new motherboard for next CPU, also giving you choice between companies.
