Often these are delayed so you've been hearing about "such-and-such Lake" for three years and by the time it arrives you are so sick of hearing it that it sounds like it is something old and obsolete.
It looks like Rocket Lake is an advanced chip on the 14nm node which is not so bad as it sounds because the process of things getting better when you shrink has been derailed as of late. Before 2005 you had explosive progress in hardware because the clock speed and power consumption both go down. Until recently the cost per transistor went down, but now it is heading up which is one of the reasons why the 4090 is as crazy expensive as it is. I've seen 22nm parts still running strong after 10 years, I think 14nm parts will hold up, but it might be 7nm parts won't have that kind of lifespan.
