AMD has very recently ... and again, re-iterated, that
Zen3 will be launching in Q4 ... the recent delay rumours were based on some silly notion that AMD was delaying Zen3 to move it to 5nm --- AMD has clarified that this is not true at all - Zen3 is on 7nm, the original roadmap has never changed, except AMD now has RDNA2 for mobile phones (samsung) to make -- those will likely be going into 5nm - so that's where that silly rumour came from.
Q4 begins in three months. Intel won't be releasing anything between now and then so nothing changes in the dynamic between the two company's parts between now and then.
