Possible reasons for about 3 month delay of Zen2 compared to what we thought. (6 months between demo and launch)
- New chip set motherboards are not ready. (PCIe4)
- Extra silicon stepping required to fix some problems in hardware.
(will the I/O die get a stepping?)
- Improving latency related things.
- Time needed to optimizing some new AI/ML or other fancy feature.
- Waiting for MS, maybe requiring some fancy new Core/Thread Handling for games and >8 core models.
- They will not have enough CPU's to launch in April, need more stock. (Who does NOT want a 7nm ZEN2?)
- Emptying the Ryzen 2000 stock.
- No need to launch early, and later launch means cheaper production, while they can fine tune and be sure of it.
-They feel a bit sorry for intel
