It is good for that information to come out. More specific information would be better, but we will get that with reviews.
AMD and Nvidia already have performance differentials in different APIs with AMD still lagging, but improving recently with the older ones on their RDNA2 arch.
Some like AMD gpus better because they are a better value in the games, settings they play, and others who like different games, settings that are a better performance value with Nvidia can't understand why somebody would prefer AMD.
Looks like Intel will be similar to AMD in this, only with the driver deficiencies and improvements being relatively larger.
Reviews will give more information and buyers can then better choose based on the performance value in the games they play and expect to play.
Edit: I also think that Intel releasing cheaper, smaller gpus initially works out well with these deficiencies. It gives people an opportunity to take a smaller chance (in terms of money) to check them out and increases the userbase to better detect problems to be solved. I hope they release them soon.
