Zero surprises there, the leaks were bang on by the sounds of it. An interesting thing is that bang for buck is similar to 7900 XT according to Techpowerup graphs although technically I guess you could have worked that out before the review (I just didn't!)
Also interesting that it's on 5nm rather than 4nm like the 4090 - no wonder the it seems badly positioned by comparison, it's like a refresh behind.
TSMC 4N is an improved 5NM process. Just like TSMC 6NM is an improved 7NM.
