You will be wrong most likely, they confirmed some days ago volume ramp will start in H2 2021. Also it's a desktop release initially this time and not mobile only which will accelerate it, a standalone CPU release has a faster market ramp. To me it sounds like you and other people are really hoping it will be delayed because in hope for a better AMD. Intel is the first with DDR5 and PCIe5 and the IPC crown will go back to Intel as well most likely, no new core for AMD this year on the other side. AMD supporters desperately hoping for ADL-S delays therefore. Not long ago many of these people called 10nm desktop dead and 10nm never will clock high and things like that.
I am sorry if my post came off as anti Intel and pro AMD. That was not my intention. As I have written many times before I have no dog in this fight.
I am a fan of both Intel and AMD. Intel has a long and quite extraordinary history of microprocessor (and other) technical achievements. During the last few years they seem to have stumbled a bit, allowing a very well-organized AMD to catch up. Intel has enormous resources and I believe the new leadership it going to put emphasis back on technological innovation, which I think is needed right now.
Finally, my basis for Alder Lake's release is just my best guess based on the problems Intel has been having getting new products and processes out the door in a timely manner. Specifically a competitive node across the product stack, and new cores. In addition, it just seems unlikely that they would release Rocket Lake and then savage that release a few months later with was will hopefully be a better performing and more efficient design.
If I am wrong then I will be happy for them (and for me) as I will buy it. Rocket Lake could be a stopgap measure until Alder Lake arrives.
I have been building PC's since the early '90's and have yet to own an AMD system. But I can't deny the technological achievement that is Zen 3.
