I guess I was thinking of this review: 6800/6800XT, not 6900XT - this was back before the Radeon drivers matured and had bumped performance quite noticeably (they really took off this summer). He was very forgiving of driver bugs in "Control" the game. He was really excited for what was coming to AMD.
His 6900XT review was a month later in Dec 2020, when the Radeon drivers were holding it back - and he was still fair to it. He stayed to the facts. He noted that the drivers weren't even "release versions"and the card was power limited. And despite the issues, he still recommended an AMD card, the 6800 instead, until AMD fixed the issues. He praised the hardware as "solid".
AMD has been improving more over time than Nvidia. The 3090 was scoring 20,286 on his Time Spy GPU portion back then, and even now the best my son sees with his EK water blocked Gaming X Trio 3090 is just over 21,000 on the latest Nvidia driver (I get 21013 with my 3080Ti). Back then Jayz 6900XT scored 18,559 due t poor drivers, and now my air cooled Sapphire hits 22,081 with the latest drivers on Dec 3rd, which is 3500 points higher for me since I got it 6 months ago, but I can still almost keep up with my son's 3090 without any OC if I just turn up power limit to +15 for 303W (mine does 264W otherwise, lame).
He still didn't give up on AMD, by doing an overclocking 6900XT video in April 2021 - but he didn't bump the power limit with something like MPT, so he didn't have a chance. Heck, I'm still at 303W power limit myself, and I'm beating my son's watercooled 3090:
