Which source says "retail availity in November 2020"? Everything I've seen says "launch", which could just mean a paper launch with retail availability in 2021, and given AMD's recent past history with "launching" with only a few hundred cards worldwide, I wouldn't expect anything until 2021. Also rumors suggest that the AIBs do not even have the GPUs in their labs yet, so only reference cards will be available in 2020. Although AMD claims to be abandoning the blower coolers on reference editions starting with RDNA2, I'm not sure how much stock I put in that statement, and the performance of dual/triple fan stock coolers will be questionable since even custom AIB versions of Navi cards, especially the lower end ones, have really horrid coolers Cough XFX Cough.
